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.
Smart electric wheelchairs are one of the special transportation tools for the elderly with disabilities with reduced mobility. For such people, mobility is the actual need, and safety is the first factor. Many people have this concern: Is it safe for the elderly to drive electric wheelchairs? DRAGON will talk to you today about why smart electric wheelchairs are safe and reliable transportation tools for the elderly.
As a 10-year practitioner in the wheelchair industry, DRAGON is here to popularize a qualified smart electric wheelchair for everyone today. Why is it a safe and reliable transportation tool for the elderly? What are the advantages of electric wheelchairs over other mobility tools for the elderly? This article is only analyzed from the perspective of the user's own control.
A qualified smart electric wheelchair first has electromagnetic brakes, releases automatic brakes, and does not slip uphill and downhill.
Smart electric wheelchairs eliminate the hassle of traditional electric wheelchairs and electric tricycles when braking, and the safety factor is higher; however, polish your eyes when purchasing. At present, many electric wheelchairs on the market do not have electromagnetic brakes, and their braking effect and driving experience are relatively poor;
When driving on a flat and smooth road, any wheelchair can walk very smoothly, but for any wheelchair user, as long as they go out, they will inevitably encounter slopes, potholes and other road scenes. In order to cope with this situation, anti-tipping wheels should be used to ensure safety.
The anti-tipping wheels of electric wheelchairs are installed on the rear wheels. This design can effectively avoid the danger of falling back due to unstable center of gravity during uphill.
Safe wheelchairs can easily brake on slippery surfaces such as rainy days, or when going up and down steep slopes, which is related to the non-slip performance of the tire. The stronger the grip of the tire, the smoother the brake, and it is not easy to fail to brake and slide on the ground. Generally, outdoor wheelchairs have wider rear wheels and more tread patterns.
National standards stipulate that the speed of ordinary intelligent electric wheelchairs should not exceed 6 kilometers per hour. The reason why the speed is set at 6 kilometers per hour is due to the different road conditions and the number of users varies greatly, so that every elderly person with disabilities with reduced mobility can travel safely.
Smart electric wheelchairs are generally rear-wheel drive, and electric wheelchairs usually use dual motors, whether dual motors or single motors are controlled by controllers to control forward and backward, steering all operations. Just move the controller joystick gently, effortless and easy to learn to operate.
When turning, the left and right motors rotate at different speeds, and the speed is adjusted according to the turning direction, avoiding the wheelchair rollover, so in theory, the electric wheelchair will never roll over.
Many people have learned about the price of smart electric wheelchairs, especially the prices of high-end smart electric wheelchairs, and shook their heads straight after shaking their heads. Some people even said that this price could add a little money to buy a car, but don't forget, no matter how good or cheap it is for the elderly, he can't drive a car, are you right?
If you understand the above aspects, you know why smart electric wheelchairs are safe and reliable travel tools for the elderly and disabled with reduced mobility.
Speaking of first aid blanket, often outdoor friends are definitely no strangers. The first aid blanket is an international emergency life-saving essential product, suitable for use in field exploration, inspection, tourism, and disasters. It is easy to carry, compact and practical.
First aid blanket are also called first aid blankets, survival blankets, cold blankets, thermal blankets and sunscreen blankets. Generally made of tin foil or aluminum film, it is divided into three types: double-sided gold, double-sided silver and double-sided gold and silver. In an emergency, the principle of reflection is used to protect against cold and keep warm.
First aid blanket are mainly used in cold places to prevent death due to hypothermia and hypothermia.
At times, once the weather changes and the temperature of the sleeping bag is not enough, on the one hand, you can spread the emergency blanket in the tent. Another option is to include a first aid blanket on the outside of your sleeping bag to give you a good night's sleep.
If you accidentally fall into the water in summer, or encounter a heavy rain and your whole body is soaked, the advantage of the first aid blanket is that even if it is completely soaked in water, as long as you open it and shake off the water droplets when you use it, it will not affect the warmth retention effect at all.
When it rains, it can also be used urgently to set up a temporary tent or a temporary rain poncho. And no matter whether it is winter or summer, in the event of an accident and you need to spend the night in the mountains without any equipment, the first aid blanket is your sleeping bag. It can provide more protection for life.
A piece of film, which is only the size of a palm after being folded, may save you and the crisis at a critical moment. In a low temperature environment, putting it on can keep 80% of its own heat from dissipating; the strong reflection makes it easier for rescuers Find. It can be used as a poncho canopy in rainy days. It can be directly covered or put on the ground as a moisture-proof pad when sleeping.
Tianjia thermal insulation layer: The thermal insulation layer is generally some fluffy material, which uses the air mixed with the fluffy to form a non-flowing air layer on the surface of the object. The air itself is a poor conductor of heat, so it can play a certain role in keeping warm. General down and cotton use this method to keep warm.
Heat-reflecting heat preservation: the use of high-reflection materials to reflect heat radiation back. The first aid blanket is a combination of these two principles. One function of the aluminum film in the aluminum-plastic film is to ensure that a layer of air on the surface of the human body is stable and does not flow. Its main function is that aluminum is a highly reflective material, which can reflect the heat radiation emitted by the human body back, and its heat reflection efficiency is as high as 90%. %above. This effectively reduces the rate of heat dissipation of the human body. Because aluminum is a metal, it is easier to tear and the strength is not high. Therefore, the main purpose of the composite plastic film is to increase the toughness and strength of the emergency blanket.
Sun protection: In the hot sun, wearing the first aid blanket can protect the body from direct sunlight.
Keep warm: When encountering cold weather in the wild, wrapping the first aid blanket can absorb the temperature and reduce the loss of body heat.
Reflective: In the event of a disaster in the wild, wrap the emergency blanket around your body, and use its reflective effect to help rescuers find the target.
Stretcher: The emergency blanket has good toughness, light weight, softness and strong plasticity, and can be used as a stretcher. A 200-pound person lay flat on the unfolded emergency blanket, and six people picked up the four corners of the emergency blanket and the middle of the edge of the blanket at the same time, which would not be damaged.
First aid blanket is mainly used in cold places, the purpose is to prevent the death of the human body due to hypothermia and hypothermia. When going out in winter, once the weather changes and the temperature of the sleeping bag is not enough, on the one hand, the first aid blanket can be spread in the tent.
Another way is to wrap the sleeping bag with a first aid blanket, which can make you sleep comfortably.

Nowadays, in terms of material selection, stretchers are made of high-quality aluminum alloy materials, and plush foam cushions, so they are not only more suitable for rescuing patients when using them but are also more convenient to use and relatively simple to operate. In particular, the current use of stretchers with ambulances can better reflect its value and characteristics. If you want to buy safe ambulance stretchers in large quantities, you can learn about the performance and characteristics of this stretcher, as well as the scope of application, including how to choose the manufacturer when buying.
The ambulance stretcher is different from other stretchers because the ambulance has a relatively small space. In selecting the stretcher-making materials, stretcher length and width, it must be light and dexterous in terms of structure, so that it is more convenient to use when going up and down the ambulance. Therefore, the stretchers used in ambulances today are all made of aluminum alloy materials, which are relatively light in weight, and appear more flexible and convenient throughout the use process.
ambulance stretchers are mainly used to pick up sick patients or patients with severe trauma. When choosing a stretcher like this, it is important to consider the patient's comfort in lying down, so that the patient can rest quietly while lying on it. Especially for patients with limb injuries, if they are not comfortable lying on the stretcher themselves, it will cause patients with severe physical injuries to be more impatient. Therefore, foam cushions will be laid on this stretcher, and lying on it will not look like a hard board will hurt people. Even if the limb injury is serious, or the patient himself is thin due to malnutrition due to illness, he will not feel uncomfortable.
The ambulance stretcher used today is relatively scientific in design, so telescopic handles are provided on both ends of the stretcher because the stretcher needs to enter the patient's room, and even cross stairways or elevators. If we treat some seriously injured people, the environment is worse, so if possible, both ends should be designed with shrink handles, which will be more convenient and practical when lifting patients.
There are no wheels on urban rescue stretchers. If the distance is relatively long, it will be more difficult to lift patients, and it will take longer. Therefore, when designing a stretcher, it is necessary to have wheels underneath, so that it can be pushed and walked when rescuing patients. This is faster than carrying and walking, shortens the time to save people, and will do a better job of saving the patient's life.
ambulance stretchers are one of the most commonly used in hospitals because when patients have heart infarction, or other need first aid, they need to call 120, then the ambulance will come to the scene with the stretcher, so now hospital ambulances will be equipped with stretchers, which can transport patients faster and more practical, directly when the ambulance to the patient area, can be pushed to the patient's room by pushing the stretcher. When you arrive at the hospital, you can push the stretcher directly to the hospital ward.
Some competitive sports are also prone to severe collisions between limbs and fractures. Stadiums such as stadiums can also be equipped with ambulance stretchers. Of course, this kind of stretcher will also be used in the field, and an ambulance can be driven directly to the scene so that it can be faster when rescuing the wounded.
When buying an reliable ambulance stretcher, since there are many manufacturers like this, you should also look at the manufacturer's production capacity through multiple comparisons before purchasing. If the manufacturer itself has a strong production capacity, it can also guarantee the quality of the stretcher.
Currently, the number of manufacturers producing stretchers is relatively large, so competition is fierce, not only in terms of technology but also in terms of price. To ensure that the stretcher purchased is highly practical and of guaranteed quality, we also need to take a look at the cost-performance ratio. If the manufacturer can sell according to direct sales, since direct sales do not have middlemen earn, and the price is cheaper, the user can make the price lower when buying.
If the manufacturer you choose cannot follow up on after-sales service, it proves that they do not dare to take responsibility for the quality of the stretchers they produce. When choosing a manufacturer to buy, you must see if after-sales service is in place. Anything that has after-sales service in place proves that the stretcher quality is relatively excellent. Buying from such manufacturers, because they have good after-sales service, users can only buy without worries.
Users, who need to buy an high performance ambulance stretcher, especially when buying a relatively large amount at a time, have learned the performance characteristics, the scope of application, and how to choose a manufacturer when purchasing this stretcher? As long as you buy stretchers according to your own needs at the time of purchase, and when selecting manufacturers, you can buy medical stretchers from approved manufacturers with confidence through comparison to see which one is in place in terms of production capacity, cost performance, and after-sales service.
