Wheelchair size

In the choice of wheelchair is also a very troublesome thing, but in order to use the convenience and safety, choose a suitable wheelchair is necessary in the purchase of a wheelchair is to pay attention to the seat width of the measurement, the best width is the user to sit down The distance between the two hips or between the two shares plus 5cm that sit on both sides after each have a gap of 2.5cm.

Wheelchair structure

Ordinary wheelchair is generally composed of wheelchair frame, wheel, brake device and seat by four parts, the following brief description of the main components of the wheelchair function.

1. The large wheel carries the main weight. Round the diameter of 51,56,61,66 cm several. In addition to the use of a small number of environmental requirements with solid tires, the use of pneumatic tires.

2. Small wheel diameter of 12,15,18,20 cm several, large diameter wheels easy to cross the small obstacles and special carpets. But the diameter is too large to make the entire wheelchair occupied space, action is not convenient. Normal ferry in front of the big round, but in the lower extremity paralyzed with a wheelchair, often the small wheel after the big round. Operation should pay attention to the direction of the best wheel can be perpendicular to the big wheel, or easy to dump.

3. Hand wheel rims are unique for wheelchairs, and are generally 5cm smaller than large wheels. Hemiplegia with one hand drive, plus a smaller diameter to choose from. Hand wheel rims are generally driven directly by the patient.

4. Tires are solid, with inflatable inner tube and no tubing inflatable three. Solid type in the ground to go faster and not easy to blasting, easy to push, but in the uneven road vibration, and with the trough with the tire width is not easy to pull out; inflatable inner tube more difficult to push, but also easy to puncture, but Vibration is smaller than the solid; no tubing inflatable type because no tubeless puncture, and the internal also inflatable, sit up comfortable, but harder than the solid push.

5. Brake wheel should have a brake every round, of course, like hemiplegia can only use one hand, had to use one hand brakes, but can be installed extension rod, manipulation of both sides of the brakes. There are two kinds of brakes: (1) notch brakes. This brake is safe and reliable, but more laborious. Adjusted on the slope can also be stopped, if transferred to a level in the ground can not stop for the failure. (2) toggle brakes. The use of lever principle, through several joints and then brake, the mechanical advantages than the concave brake strong, but the failure faster. In order to increase the patient's braking force, often in the brakes to extend the pole, but the rod easy to damage, if not often check will affect the safety.

6. The seat height, depth and width depends on the patient's body, the material texture also depends on the disease. Generally deep 41,43 cm, width 40,46 cm, height 45,50 cm.

7. cushion to avoid pressure sores, cushion is an indispensable element, the choice of the mat should also be a high degree of attention.

8. Foot and leg care can be crossed on both sides of the type, or both sides of the separate, both of which are able to use to swing to the side and can be removed for the best. Must pay attention to the height of the foot. Foot care is too high, then the hip hip angle is too large, more weight added to the calcaneal tubercle, easy to cause the Department of pressure sores.

9. backrest back with high and can be tilted and can not tilt the points. Such as the balance of the trunk of the patient and better control, can choose a low-back wheelchair, so that patients have a greater degree of activity. On the contrary, to use high-back wheelchair.

10. armrest or arm support generally higher than the seat surface 22.5 ~ 25cm, some arm can adjust the height. But also in the arm on the shelf shelves, for reading, dining.
