Wheelchair is an important tool for rehabilitation. It is not only a walking tool for the physically disabled and the disabled, but also a tool for them to take part in physical exercise and social activities with the help of wheelchair. There are many wheelchair accessories, different wheelchair accessories have different functions. Among them, manual wheelchair accessories and electric wheelchair accessories also have certain differences, and different wheelchair brand accessories will also have certain differences. What are the wheelchair accessories? What are their respective functions?
6. Chair seat
Its height,
depth and width depend on the patient's body shape, and its material texture also depends on the disease type. Generally, the depth is 41, 43cm, the width is 40, 46cm, and the height is 45, 50cm.
7. Cushion
In order to avoid pressure sores,
great attention should be paid to the cushion. Egg crate or roto cushion may be used as far as possible. This kind of cushion is composed of a large piece of plastic with a large number of papillary plastic hollow columns about 5cm in diameter. Each column is soft and easy to move. After the patient sits on it, the pressure surface becomes a large number of pressure points. When the patient moves a little, the pressure points change with the movement of the nipple, In this way, the pressure point can be changed continuously to avoid pressure sore caused by pressing the same part frequently. If there is no such cushion, then it is required to use a layer of foam plastic. The thickness should be 10cm, the upper layer is 0.5cm thick high density polychloroformate (polyarethane) foam plastic, the lower layer is the same density plastic with medium density, the high-density support is strong, the middle density is soft and comfortable. In the sitting position, the pressure of the ischial tubercle is very high, often 1-16 times higher than the normal capillary pressure, which is easy to form pressure sores due to ischemia. In order to avoid excessive pressure here, we often dig a piece on the corresponding cushion to make the ischial tubercle overhead. When digging, the front should be 2.5cm in front of the ischial tubercle, and the side should be 2.5cm outside the tubercle, with a depth of about 7.5cm. After digging, the cushion is concave, and the gap is behind. If we use the above cushion and incision, we can effectively prevent the occurrence of pressure sore.
8. Foot support and leg support
Leg support can be across the two sides, or separated from the two sides, both of which can swing to one side and can be removed for the best. Pay attention to the height of the foot rest. If the foot support is too high, the hip flexion angle will be too large, and the weight will be more added to the ischial tubercle, which is easy to cause pressure sores.
9. Back rest
The back can be divided into height, tilting and non tilting. If the patient has a good balance and control of the trunk, the wheelchair with low back can be selected to make the patient have a greater range of motion. On the contrary, we should choose high back wheelchair.
10. Armrest or armrest
Generally,
it is 22.5 ~ 25cm higher than the seat surface, and some arm brackets can adjust the height. In addition, a lapboard can be built on the arm bracket for reading and dining. Different wheelchair brands use different styles and materials of armrest or armrest. You can choose according to your own needs.
