With the development of rehabilitation assist devices, outdoor electric wheelchairs have been given more caring designs. In addition to the basic mobility functions, the design has started to take more into consideration for the actual use of the elderly. When choosing an electric wheelchair, the elderly and disabled should take into account the environment they use and choose the right style. At the same time, they should also consider their actual needs and add more functions.
There are many types of electric wheelchairs on the market, which can be divided into aluminum, light materials and steel by material. Steel wheelchairs are relatively heavy in weight and the main structure is made of carbon steel, alloy steel or stainless steel. The process of steel tube wheelchairs is constantly improving and is now very mature. Many wheelchair manufacturers still choose steel tubes for the body of the wheelchair but its weight still does not reach the desired effect. With the demand for higher light weight, it is difficult to make a breakthrough in steel wheelchairs.
The weight of aluminum wheelchairs is about 10 pounds less than that of steel tubes, the strength is comparable to that of steel, and the density is 1/3 of that of steel. Compared with other materials, the lightweight effect is good, and it has good corrosion resistance, good recyclability, easy processing and shaping, and the surface spraying and anodizing processes are mature. Its relatively low production cost, perfect process technology and no need for professional production equipment and technology make aluminum alloy the most ideal and popular material for lightweight comprehensive performance at present. Aluminum alloy electric wheelchairs are more suitable for users with high floors, humid environments and frequent moving.
Electric wheelchairs can be divided into lead-acid battery-driven and aluminum battery-driven electric wheelchairs according to their batteries.
The lead-acid battery electric wheelchair adopts the latest electromagnetic brake technology, so it does not slip backwards uphill and has no inertia downhill. It is equipped with technically mature universal controller for more precise direction, easy driving and flexible control.
Another kind of electric wheelchair adopts large-capacity lithium battery as the power source, with stronger power. And it adopts aluminum alloy tube frame and ergonomic design to realize the structure of electric wheelchair with high strength, high load-bearing, light weight, small volume, and ready to fold. Lithium batteries are more environmentally friendly and have a longer service life than their plumbing counterparts.
Outdoor Electric wheelchairs can be divided into ordinary wheelchairs and special wheelchairs according to the type of use. Special wheelchairs can be divided into leisure sports wheelchairs, electric wheelchairs, stair climbing wheelchairs and so on, which are designed according to the different needs of users. There are also some special electric wheelchairs, depending on the condition of the patient, with a variety of different accessories, such as enhanced load capacity, special cushions or backrests, neck support systems and so on. In use, it is also different from the general electric wheelchair, because of the wide range of accessories, the operation is more troublesome, and is usually used for patients with serious illness or severe limb or trunk deformation. For the specific needs of patients with certain disabilities, there are a variety of special wheelchairs. Such as unilateral passive wheelchair, special wheelchair for going to the toilet, some wheelchairs with lifting devices, etc.
There are also special wheelchair docking carts that can be adjusted in width to accommodate a wide range of wheelchair sizes and used in conjunction with wheelchairs to help with stair access.
According to the usage scenarios, three different applications have been developed in the category of electric wheelchairs, namely indoor, outdoor and indoor/outdoor wheelchairs.
Indoor wheelchairs are suitable for indoor or outdoor use in close proximity. They are generally lightweight, with small front wheels and a small radius of rotation, and are mainly used by paraplegics or hemiplegics.
Outdoor wheelchairs can be used on unstable surfaces and have a large battery capacity and long battery life. Even on uneven surfaces, this type of wheelchair can travel, usually at a faster speed than indoor power wheelchairs.
Indoor and outdoor general-purpose wheelchairs combine the advantages of the above two types of wheelchairs, and they are general-purpose products that take into account lightness while ensuring range. This type of electric wheelchair usually needs to move on smooth and solid ground, and the battery capacity is usually not too large and the distance traveled is limited.
Nowadays, the pursuit of electric wheelchairs is not only about mobility, but also about meeting the emotional needs of users. Automation and information technology are the inevitable direction of wheelchair development.

The condition of critically ill patients is complex, dangerous and rapidly changing, and there may be different degrees of complications and some unexpected situations during the transfer. Therefore, accurate and comprehensive assessment of the patient's condition by nurses before transporting the patient is the key to safe transfer. Before transporting all patients, emergency physicians and nurses together fully assess the possibility of transport, including the patient's consciousness, vital signs, medication, respiratory condition, and potential safety hazards that may occur during transport according to the patient's condition. According to the assessment, make appropriate preparations.
First, obtain the consent of the family When the nurse receives the medical order to transport the patient, she will contact the patient's family in the first time, explaining where the patient is to be transported, the purpose and how many family members need to accompany the patient, and how to cooperate, and informing the patient of the possible problems on the way, so as to avoid the doctor-patient dispute caused by the patient's lack of understanding when the patient has an accident on the way, which will affect the safe transport. Then sign the informed consent form for patient transport. Next, keep the patient's airway open and check whether the artificial airway is firmly fixed to prevent the catheter from slipping out during the transfer. Prevent asphyxia and misaspiration, and ensure adequate oxygen supply. Aspirate the secretions in the airway before transport. In addition, keep all kinds of tubes smooth, tightly connected and properly fixed to prevent distortion, pressure and dislodgement. Ensure that the infusion pipeline is smooth and the drug input is uniform so that the treatment is uninterrupted during the transfer.
Proper use of transfer tools including China Transport Chair for sale Preparation of items, drugs and instruments required for transfer Prepare different resuscitation drugs according to the patient's condition, such as epinephrine, atropine, lidocaine hydrochloride, niclosamide, loperine, diazepam, sodium lactate Ringer's solution, etc. At the same time, prepare cardiac monitors, oxygen bags, simple breathing airbags, aspirators, etc., and if necessary, prepare portable ventilators. When using portable oxygen cylinders to give oxygen, check whether the oxygen device is smooth, and try to avoid using oxygen bags for oxygen supply, because the oxygen concentration and oxygen flow rate of oxygen bags are difficult to estimate.
There are great risks in the transfer and examination of critically ill patients. Medical staff should contact the receiving department well before transferring patients to ensure that the receiving department has been informed of the patient's condition and is prepared. Nurses should estimate the distance to the department and the time required and contact the special elevator for emergency patients. In case of various tests, make an appointment in advance to ensure that the patient arrives in time for the various tests. The entire transfer process should be escorted by medical staff, and the nursing staff should keep records of the patient's consciousness, vital signs and accidental treatment during the transfer to prevent medical disputes.
The qualification and ability of the escorting personnel are related to the safety of the patient. In addition to the general staff, physicians and senior nurses with on-site cardiopulmonary resuscitation (CPR) skills should be available for the transport of critically ill patients, and they should have certain experience in resuscitation and emergency response capabilities. During transportation, timely and accurate judgment and treatment should be made according to changes in the condition.
The rapid onset and change of the condition of the critically ill patients in emergency medicine is a negative event for the patients, which must cause psychological stress, and the patients should be guided to respond positively to this stimulus so that they can adapt to the role change as soon as possible. Therefore, the psychological care of patients and their families should be done at the beginning of the transport work, so that patients feel safe. During the transfer process, nurses should work in an orderly manner and be skilled in their movements, place the patient in a comfortable position, accompany the patient at the end, and give careful, patient and thorough services to eliminate fear.
When determining the transfer of patients, handling requires accurate movements, and light, steady and fast, avoiding vibration. Patients with critical conditions or cervical and lumbar fractures should be transported by 3 to 4 people at the same time, keeping the head and trunk in a straight position. Patients should be transported with a restraint belt to prevent falling injuries, covered with good clothing, pay attention to warmth, position placement according to the condition and injury, general light casualties to take the supine position, cranial injury to the lateral position or head to the side to prevent the back of the tongue or secretions blocking the respiratory tract, chest injuries to take a semi-recumbent position or injury side down the low slope position to reduce respiratory distress, abdominal injuries to take the supine position knee pad high, so that the abdomen relaxed, shock patients to take supine in a concave position, etc. Patients with infusion should fix the needle to prevent it from coming out and causing extravasation of medicine; those with drainage tube should be fixed properly to prevent poor drainage caused by folding, twisting and pressure of drainage tube. Ensure that the intravenous infusion is smooth during the transfer so that the medication can be used during resuscitation. Keep the head at the end of the big wheel, which can reduce the vibration because of the slow and steady speed of the big wheel. The head is always at the high end when going up and down the slope to avoid causing discomfort to the patient. Medical personnel always guard the patient's upper body near the head end during the transfer process to facilitate observation of the patient's face color, pupils, respiratory changes, etc. Effective monitoring, bring a good transfer monitor during the transfer process, and closely monitor the patient's vital signs and mental status. Pay particular attention to the patient's respiratory rate, rhythm and depth. Patients with clear consciousness should have brief conversations at regular intervals to determine changes in consciousness. Patients with impaired consciousness should keep track of pupil changes by carrying a flashlight with them and make corresponding monitoring records. The therapeutic care measures that should be done on the way are not missed, and various therapeutic measures are kept effective. If the patient suddenly appears in respiratory cardiac arrest during the transfer, the patient should be immediately resuscitated in place, while calling nearby medical personnel to prepare drugs and instruments to assist in the resuscitation work, so as to win the first opportunity for the patient's resuscitation.
When transferring patients, after escorting the patients to the destination, medical and nursing staff of the receiving department will place the patients together, including lying position, liquid, drainage tube, oxygen, etc., and then make detailed bedside handover, including the handover of medical records, condition before and after the transfer and during the journey, vital signs, medication, special treatment measures, psychological state of the patients, etc. After the medical and nursing staff of the receiving department understand the handover content is correct, they will make the handover records. After the medical and nursing staff of the receiving department understand the content of the handover is correct, they will record the handover, and finally the medical and nursing staff of both sides will sign their full names to complete the handover process. This prevents the safe transfer of patients from being affected by errors during the handover.
To ensure that patients can be safely transported, nurses play a leading role, not only to fully assess the condition, but also to have excellent professional knowledge about China transport chair for sale, and to be able to deal with patients in a timely and correct manner when complications occur. It is necessary to establish a set of nursing routines for safe in-hospital transfer of critically ill patients.
How to choose an electric wheelchair? The first thing we need to consider is that electric wheelchairs are for users, and each user's situation is different. From the perspective of the user, based on basic data such as height and weight, daily needs, use environment and special surrounding factors, etc., a comprehensive and detailed assessment should be carried out from the perspective of the user, so that effective selection can be carried out, gradually subtracted until a suitable electric wheelchair is selected.
How to choose an electric wheelchair? In fact, the conditions for selecting electric wheelchairs and ordinary wheelchairs are basically similar. When selecting the seat back height and seat width, the user can sit on the electric wheelchair, the knees are not curved, and the calf can be naturally lowered at a 90° right angle. The appropriate width of the seat is, at the widest position of the hips, add 1-2cm to the left and right.
If the user sits, the knees are slightly high, and the legs will be curled, and it is very uncomfortable to sit for a long time. If the seat surface is narrow, the sitting will be crowded and wide, and long-term sedentary will cause secondary injuries such as spinal deformation.
Then consider the weight of the user. If the weight is low, the use environment is flat, and the brushless motor is cost-effective; if the weight is heavy, the road condition is not very good and needs to drive long distances, it is recommended to choose a worm gear motor (brushed motor).
The easiest way to detect the power of a motor is a climbing test, whether the climbing test motor is easy or slightly strenuous. Try not to choose the motor of the horse-drawn cart. There will be many faults in the later stages. If the user has more mountain roads, it is recommended to use a worm motor.
The battery life of an electric wheelchair is also a concern for many users. To understand the properties of the battery and the AH capacity, if the product description is about 25 kilometers, it is recommended that the budget life be 20 kilometers, because the test environment and the actual use environment will differ. For example, the battery life in the north will be reduced in winter, and try not to drive an electric wheelchair out during colder times, which will cause great and irreversible damage to the battery.
6AH battery life 8-10 km
12AH battery life 15-20 km
20AH battery life 30-35 km
40AH battery life 60-70 km
Battery life is related to battery quality, weight of electric wheelchairs, passenger weight, and road conditions.
How to choose an electric wheelchair? It is also important to note the overall width of the electric wheelchair. Some families have narrow doors and need to measure the width and choose an electric wheelchair that can be freely accessed. Most electric wheelchairs have a width of 55-63cm, and some have made it more than 63cm.
When buying products, you need to carefully understand the instructions, check whether the product label brand is consistent with the manufacturer. If the product label brand is not consistent with the manufacturer, it is an OEM product.
Finally, let's talk about the warranty time. Most of them are one-year warranty for the whole vehicle, and there are also separate warranties. The controller is regular for one year, the motor is for one year, and the battery is 6-12 months.
There are also merchants who have long warranties, and ultimately follow the warranty instructions in the manual. It's worth noting that some brands have warranties based on the factory date, and some are based on the sell-by date.
When buying, try to choose a production date that is closer to the date of purchase, because most electric wheelchairs have batteries that are installed directly on the electric wheelchair and are sealed and stored and cannot be maintained separately. If left for a long time, the battery life will be affected.
Friends who have been using electric wheelchairs for a long time may find that the battery life is slowly short, and an inspection finds that the battery drum is packed. Either you run full and run out of power, or you can't charge it how you charge it. Don't be in a hurry, tell you how to properly maintain your battery today.
In the driving state of the electric wheelchair, the battery itself will heat up, plus the weather is hot, the temperature of the battery is even as high as 70 ℃. In the case of the battery not cooled to the ambient temperature, the electric wheelchair will be charged immediately as soon as it stops, which will exacerbate the battery's lack of water, reduce the service life of the battery, and increase the risk of battery charging.
It is recommended to park the electric vehicle for more than half an hour and charge it after the battery is fully cooled. If the battery or motor is abnormally heated during the driving of the electric wheelchair, please go to the professional electric wheelchair maintenance department for inspection and repair in time.
The battery also heats up during charging, and if charged under direct sunlight, it can also cause the battery to lose water and cause a drum bag to the battery. Try to charge the battery in a cool place or choose to charge an electric wheelchair in the evening.
Charging an electric wheelchair with a mismatched charger may result in damage to the charger or damage to the battery. For example, using a charger with a large output current to charge a small battery can easily cause the battery to charge the drum pack.
It is recommended to go to a professional electric wheelchair after-sales repair shop to replace the matching high-quality brand charger to ensure the charging quality and prolong the service life of the battery.
Many electric wheelchair users often charge all night for convenience. The charging time often exceeds 12 hours, and sometimes forgets to cut off the power to charge for more than 20 hours, which will inevitably cause great damage to the battery. Charging multiple times for a long time can easily cause the battery to charge the drum due to overcharging. Generally, electric wheelchairs can be charged for 8 hours with a matching charger.
Try to keep the electric wheelchair battery fully charged before traveling, and depending on the actual range of the electric wheelchair, you can choose to take public transportation for long-distance travel.
After reading this article, do you have a general understanding of how to choose an electric wheelchair?
China electric stair climbing dolly is a new type of stair climbing equipment. Electric load stair climbing machines are widely used in transportation, distribution, and other related industries. It can reduce the burden of heavy object handling at work and improve work efficiency. Without the help of others, a stair-climbing trolley, which can quickly complete the work of heavy objects upstairs, is efficient transportation and distribution equipment.
How can we find the proper stair climber? What kind of electric stair climbing car is good? Share some relevant information for your reference.
China electric stair climbing dolly is divided into two parts: the control part and the body part.
The primary function of the control part is to control the motor movement of each part of the car body, including the forward and reverse rotation of the front and rear gears and the forward and reverse process of the front and rear wheels.
The critical part of the car body is the climbing mechanism. The climbing mechanism adopts two sets of rack and pinion mechanisms, each located at the front and rear.
The principle of electric stair climbing dolly is that the front gear rotates forward to lift the front load and the front wheel when the first step is started. When the front wheel rises to a height of a degree, the rear wheel turns, and the front wheel is placed on the next step. The rear wheel stops rotating, the front gear reverses, and the rear gear rotates forward so that the middle of the car body can be lifted; at this time, the front and rear wheels move forward at the same time so that the seat of the car also falls to the upper step, and then reverse the rear gear and lift the rear wheel Level with the front wheel and move on. In this way, the car went up a step smoothly. In this way, the cycle has been continued, and the trolley can smoothly climb the stairs.
Compared with other cars that can go upstairs, China electric stair climbing dolly has the following advantages:
(1) The design principle is intuitive.
(2) The trolley has a simple structure and is easy to manufacture.
(3) Stairs with variable height can be climbed.
(4) The whole climbing process can keep the body moving safely and smoothly.
(5) According to the principle of ascending, descending steps can also be performed.
The most widely used materials for electric dolly stair climbers on the market are carbon steel and aluminum alloy. The carbon steel material is economical and can achieve high-strength rigidity, making the machine more durable; the aluminum alloy material is lighter and easier to carry. Its material strength is equally strong and durable.
China electric stair climbing dolly battery recommends the use of lithium batteries. Lithium batteries have a high cost, strong energy density, and are relatively lightweight, which can better control the weight of the entire machine (lead-acid batteries are about 4-5 times heavier than lithium batteries); it can significantly reduce the labor generated by carrying.
We will inevitably encounter bad weather and environment in our daily distribution process. The electric dolly stair climber must provide a safe operation design and corresponding protection measures such as waterproof and dustproof. It can effectively avoid water splashing and dusty situations in life and prevent the machine from malfunctioning during operation.
Solid tires are wear-resistant and puncture-resistant, and are more suitable for use in harsh environments; pneumatic tires have better shock resistance. In the process of handling heavy objects such as household appliances and fragile goods, pneumatic tires can better buffer and reduce damage to goods.
The key to using a stair climbing machine is the operation skills. A good stair climbing machine should be easy to learn and master the operation quickly.
In addition to skilled operation skills, the machine operation switch adopts a touch-type (click to move) design, press to move, release to stop; the touch-type design can effectively avoid accidents during distribution and handling.
It is a mistake to blindly pursue speed without considering the safety of operators and items. The rate of the electric dolly stair climber needs to be reasonably assumed. The speed should be well designed to ensure the weight limit of the operator and the safe handling of the equipment. It is recommended to have two speeds, one fast and one slow. The slow gear setting is usually used for beginners to practice. After you are proficient, you can choose the quick file to improve work efficiency.
When working indoors, it is necessary to consider whether the noise generated during the operation of the stair climber affects people's everyday life. When the electric dolly stair climber operates, most noise comes from the motor. To better control the noise, the selection of the motor is also a knowledge. The brushless DC motor is recommended. To ensure the maximum load of 200 kg, the noise can be kept at a reasonable level and controlled below 70 decibels.
The core technology is like the human brain for electric machines like the electric dolly stair climber. The control system of the heavy object climbing operation must be stable, have a low failure rate, and durable. Therefore, it is essential to choose an experienced R&D team who can provide strong support for our core technology. This will give you more peace of mind when using the device.
The quality and function of the product itself must be considered when purchasing a suitable electric dolly stair climber, but after-sales service is also essential. Choosing a company with strength and brand protection can solve your worries.
1. If the electric stair climbing dolly works in a high temperature and high humidity environment like this summer, it is prone to performance degradation, so the workers should usually place the stair climbing dolly indoors to ensure that its metal The structure is more stable, can exert its performance, and can prolong the life of the battery at the same time!
2. Do not put the stair climber in the car's trunk. After using the electric dolly stair climber, many customers directly prevent the stair climber from the box and then park it in the sun exposure environment because of the electric dolly stair climber. The power supply is the battery. For any storm, we must be careful not to prevent it from being in a high temperature and airtight environment, which is a dangerous thing.
3. It is necessary to regularly check the parts of the electric dolly stair climber to effectively avoid the damage of the plastic parts from breaking or deforming due to the high temperature and ensure the safety of the stair climber. Before using the stair climbing machine, carefully check the screws and other parts of the stair climbing machine to ensure that there is no problem before starting to use it.
4. Pay attention to charging in time. In summer, it is necessary to change frequently to ensure that the battery is always in a "full" state to ensure the battery life and the electric dolly stair climber operate normally. At the same time, choose to charge it in a dry, ventilated, and no direct sunlight environment, but do not charge overnight, and the charging time should not be too long. It is recommended to set it at least once a month. Otherwise, it will seriously affect the battery life!
