The first thing we have to take into account is that electric wheelchairs are all for the user, and each user's situation is different. From the user's point of view, we must make a comprehensive and detailed assessment based on the individual's limb consciousness condition, basic data such as height and weight, daily needs, usage environment and special surrounding factors, etc., in order to make an effective selection and gradually subtract until we choose a suitable electric wheelchair.
In fact, the conditions for selecting an electric wheelchair and an ordinary wheelchair are basically similar. When selecting the seat back height and seat width, the following selection method can be used: the user sits on the electric wheelchair without hooked knees and can naturally lower the lower legs at a 90° right angle is most appropriate. The appropriate width of the seat surface is the widest position of the hips, plus 1-2cm on each side.
If the user sits, knees slightly high, there will be curled legs, sitting is very uncomfortable, if the selection of the seat surface is narrow, sitting will be more crowded, wide, long-term sedentary will cause secondary injuries such as spinal deformation.
Then also consider the weight of the user, if the weight is light, the use of environmental road flat, brushless motor cost-effective; if the weight is heavy, road conditions are not very good, the need for long-distance travel, it is recommended to choose worm gear motor (brush motor).
The easiest way to test the power of the motor is to climb the test, climbing to test the motor is easy or slightly strained. Try not to choose a small horse-drawn motor, there will be many failure problems later, if the user is more hilly, worm gear motor is recommended.
Electric wheelchair range is also a lot of users concerned about the link, to understand the properties of the battery, and AH capacity, if the commodity description of about 25 km, it is recommended that the budget range of 20 km, because the test environment and the actual use of the environment will be different. For example, the northern winter range are reduced, and the colder hours try not to drive the electric wheelchair out, will cause great and irreversible damage to the battery.
Generally speaking, the battery in AH capacity and range is approx.
- 6AH range 8-10km
- 12AH 15-20km range
- 20AH 30-35km range
- 40AH range of 60-70 km
The battery range is related to the battery quality, the weight of the electric wheelchair, the weight of the rider and the road conditions.
Long-term users of electric wheelchairs may find that the battery range is slowly shortened, and a check reveals that the battery is bulging. Either a full charge on a run on no power, or how to charge is not charged. Do not worry, today will tell you how to properly maintain the battery.
Electric wheelchair in the driving state, the battery itself will be hot, coupled with the hot weather, the temperature of the battery is even up to about 70 ℃, the battery has not yet cooled to the ambient temperature situation, electric wheelchair as soon as it stops charging, will intensify the battery's lack of liquid water loss, reduce the service life of the battery, and intensify the risk of battery charging drum.
It is recommended to stop the electric wheelchair for more than half an hour and wait for the battery to cool sufficiently before charging. If the battery and motor are abnormally hot during the driving process of the electric wheelchair, please go to the professional electric wheelchair maintenance department for testing and repair in time.
The battery will also heat up during the charging process, and if it is charged in direct sunlight, it will also cause the battery to lose water and cause a bulge on the battery. Try to charge the battery in the shade or choose to charge the electric wheelchair in the evening.
Using a mismatched charger to charge the electric wheelchair 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 is very likely to cause the battery to bulge.
It is recommended to go to a professional electric wheelchair after-sales repair store to replace the matching quality brand charger to ensure the quality of charging and extend the life of the battery.
Many electric wheelchair users often charge throughout the night for convenience, charging time often exceeds 12 hours, and sometimes even forget to cut off the power charging time of more than 20 hours, this is bound to cause great damage to the battery. Multiple long-time charging can easily lead to the battery being filled with drums due to overcharging. The general electric wheelchair can be charged for 8 hours using a matching charger.
Try to keep the electric wheelchair battery in a fully charged state before traveling, and according to the actual electric wheelchair range activities, long-distance travel can choose to take public transportation.
Many cities have fast-charging stations. Using fast-charging stations for high-current charging can easily lead to water loss and bulging of the battery, thus affecting the battery life, so try to reduce the number of times you use fast-charging stations for charging.
Multifunctional chest decompression and handle-operated exhaust gas drainage
Needle for puncture, including pen tube, needle for decompression and abduction and drainage cannula, decompression
The expiratory decompression needle from China factory consists of a needle base for expiratory and decompression puncture and a needle body.
The drainage cannula consists of the base of the drainage cannula and the body of the cannula.
Pneumatic needle for puncture and positioning in the drainage cannula, needle for decompression and abduction and drainage
The bushings are inserted together and positioned in the handle tube as one unit. Less
At the base of the pressure relieving puncture needle is a one-way air valve chamber and the one-way air valve chamber has
Valve type One-way valve • Insert the drain cannula into the front of the base of the decompression / extraction needle.
The center hole of the base, in the center, the utility model uses the handle tube type packaging.
It has good damage resistance, can be sterilized repeatedly and can simultaneously decompress and exhale from the chest cavity.
And drainage function, very suitable for quick rescue of the injured in the field。
The purpose of the China decompression needle manufacturer, if not sharp, is to decompress by converting a tension pneumothorax into an open pneumothorax. If you can do this quickly enough, a direct tube thoracostomy is a reasonable alternative. In a pinch, anything that opens that side of the chest will do its job - you can stick a knife in and find something to hold the hole open, maybe even a knife handle. Just a 14-hole China decompression needle is typically used ubiquitous in emergency rooms and hospitals, so it's the first helpful tool to get the job done quickly. You usually don't have time to scratch your head waiting for MacGyver's inspiration.
The basic principle of emergency decompression needles is to insert a catheter into the pleural space to create a channel for the air to escape and the accumulated pressure to escape. Although this approach is not the definitive treatment for tension pneumothorax, emergency needle decompression stops its progression and helps restore cardiorespiratory function slightly. For people with large pectoral muscles, China decompression needle length can be an issue and a long needle or vascular catheter may be needed.
Usually a large diameter vascular catheter is inserted into the midclavicular line between the second or third intercostal space. The use of a large diameter catheter is important because hemothorax can be associated with pneumothorax and the patient may require immediate IV fluids. A standing position may be helpful if it is not inappropriate due to the cervical spine or injury. This is the bridge to the definitive treatment of tubular thoracostomy. The catheter remains in place until the thoracic catheter is placed.
The procedure is as follows:
Locate anatomical landmarks and quickly prepare the puncture site with an iodine-based solution
Insert a large diameter decompression needle from China factory with catheter into the second intercostal space, above the third rib along the mid-clavicular line, 1-2 cm from the edge of the sternum (i.e. to avoid injury to the internal mammary artery)
Use a catheter or needle at least 5 cm long inserted perpendicular to the chest; however, it is important to note that in some patients the chest thickness may be greater than 5 cm and the inability to relieve symptoms may be associated with insufficient needle length ; longer pots are recommended (eg 8 cm)
Once the needle is in the pleural cavity, listen for the hissing of the escaping air to confirm the diagnosis of tension pneumothorax (note this on the patient's medical record); the air outlet may not be visible in places with high ambient noise levels
Remove the needle when the catheter is in place.
Secure the conduit in place and install the flicker valve.
Immediately after decompression, the needles begin preparing for thoracostomy tube insertion. Then reassess the patient, noting major aspects of trauma management (eg, airway, breathing, circulation). The hemothorax component is characteristic of tension pneumothorax; therefore, patients may require additional thoracostomy catheters.
Follow-up chest radiographs were taken to evaluate lung re-expansion, thoracostomy tube placement, and correction of mediastinal displacement .
A follow-up blood gas test (arterial blood gas) is required. All patients with tension pneumothorax were hospitalized.
The purpose of the needle is to allow the air that created the pneumothorax to escape, thus making room for the lung to re-expand.
With the growing population base of the elderly, electric wheelchairs are becoming more and more popular. However, the steps and methods used by many elderly people or people with limited mobility when using electric wheelchairs are unscientific, and it is easy to shorten the service life of electric wheelchairs and even cause users to be injured.
The electric wheelchair is a multi-functional wheelchair with artificial intelligence manipulation based on the manual wheelchair, superimposed with high-performance power-drive devices and other configurations. Electric wheelchairs can enhance the self-care ability of users and save a lot of nursing costs for families. The main users of electric wheelchairs are the elderly and the disabled. Especially for elderly friends, they must learn scientific and reasonable using methods and steps before operating the electric wheelchair to ensure that the function of the wheelchair can be fully utilized.
It's depend on the needs of the user. If the user need to drive on uneven roads, they should choose a outdoor electric wheelchair with better obstacle-crossing function. If users often need electric wheelchairs to climb hills, they should choose a powerful model. If users want to go out frequently, they could choose a reclining wheelchair. If the user is a high paraplegic patient, he or she could choose a standing electric wheelchair.
It varies from person to person, and people can also choose to customize one. You can choose the most suitable electric wheelchair according to your specific needs.
Whether the electromagnetic brake is in the closed state. If the brakes are not closed, the wheelchair may slide back when the user tries to get into the wheelchair, creating a hazard. Accidental falls are the cause of paralysis in many elderly people, and we must also pay attention to avoid such dangers as much as possible. In addition, the electric wheelchair cannot be driven normally when the clutch is on. Please check carefully before use.
Is the tire pressure normal? When the tire pressure of the electric wheelchair is abnormal, it will deviate when driving. If the direction of the wheelchair cannot be controlled, it is very dangerous for the disabled or the elderly in the wheelchair.
The power supply should be turned off. When sitting in the electric wheelchair, make sure that the power supply is turned off, otherwise, if you accidentally touch the controller or joystick, the electric wheelchair will slide out uncontrollably, which will cause a safety accident;
The footrests must be upright before getting into the wheelchair. For safety reasons, do not step on the pedals to get on and off the wheelchair. On the one hand, it is easy to cause damage to the wheelchair pedals or other accessories, and on the other hand, it is easy to cause people to slip and fall. Standard operation is the premise of all convenience and comfort in use.
The most important is to fasten your seat belt. Seat belts are considered redundant most of the time, but it is necessary to develop a good habit of wearing seat belts and have safety awareness. In the event of an accident, the seat belt is the last guarantee of life.
Put down the pedals and place your feet flat on the pedals. Keeping your feet shoulder-width apart helps stabilize your pelvis and shares your body weight. The correct sitting posture needs to have a certain angle between the upper and lower legs, otherwise it is easy to get bedsores. If the elderly have cough, asthma, bronchitis and other diseases, when the cough is severe, please put away the pedals, step on the ground, or stand coughing is safer to prevent the elderly from suffocating due to incorrect posture. If the body is on the hips and the seat is too deep, take an additional small cushion and place it vertically behind the patient.
Turn on the power and gently push the controller joystick forward to drive the electric wheelchair forward. Be careful not to accelerate suddenly, accelerate slowly and observe the surrounding road conditions before accelerating.
Strictly abide by the traffic rules, do not run red lights, do not take the fast lane, and pay attention to avoid pedestrians and non-motor vehicles.
When encountering an obstacle or a section with a steep slope, please take a detour, or ask passers-by to assist in passing, and do not pass without certainty, so as to avoid potential safety hazards.
The above is the correct way to use the electric wheelchair.
