How many parts can wheelchairs be divided into? Introduction to wheelchair suppliers

brake

The large wheels should have brakes on each wheel. Of course, for hemiplegic individuals who can only use one hand, only one hand brakes can be used. However, extension rods can also be installed to operate the brakes on both sides. There are two types of brakes: (1) notch brakes. This brake is safe and reliable, but it requires more effort. After adjustment, it can also brake on slopes. If it cannot brake on flat ground when adjusted to level 1, it is considered invalid. (2) Elbow brake. By utilizing the lever principle and braking through several joints, its mechanical advantages are stronger than notch brakes, but it fails faster. To increase the braking force of the patient, an extension rod is often added to the brake, but this rod is prone to damage and may affect safety if not checked regularly.

seat 

Its height, depth, and width depend on the patient's body shape, and the material texture also depends on the disease type. Generally, the depth is 41cm and 43cm, the width is 40cm and 46cm, and the height is 45cm and 50cm.

Foot and leg rests

Leg supports can be either side spanning or side separated, both of which are ideal for swinging to one side and being detachable. Attention must be paid to the height of the footrest. If the foot support is too high, the hip flexion angle will be too large, and more weight will be added to the ischial tuberosity, which can easily cause pressure ulcers in that area.

backrest

The backrest can be of different heights and can be tilted or not tilted. If the patient has good balance and control of the torso, a low back wheelchair can be used to provide greater mobility for the patient. On the contrary, a high back wheelchair should be chosen.
