Big wheel

Carry 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.

Small wheel

Diameter of 12,15,18,20 cm several, large diameter wheel 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.

Hand wheel rims

Wheelchair supplier

Ideal for wheelchairs, the diameter is generally 5cm smaller than the big rim. (Wheelchair supplier) hemiplegia with one hand drive, plus a smaller diameter to choose from. Hand wheel rims generally driven by the patient directly, if the function is poor, easy to drive, can have the following changes: ⑴ in the hand wheel surface with rubber to increase the grinding Sassafras force. ⑵ increase around the hand wheel around the knob (knob). Push to have the following: ① level push. For C5 spine injury. So, brachial biceps sound, hand on the push, the elbow can push the car forward. If there is no horizontal push, you can not push. ② vertical push to put. For rheumatoid arthritis when the shoulder joint movement is limited. So can not use the level of push. ③ bold push. For patients with severe finger movement and not easy to fist, but also for osteoarthritis, heart disease or elderly patients. (Hand wheelchair driven by hand-driven Bing on hand wheel)

Tires

There are three kinds of solid, inflatable inner tube and tubeless inflatable. 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.

brake

Large rounds should be braking each round, of course, like hemiplegia can only use one hand, had to use one hand brakes, but also can be installed extension rod, manipulation of both sides of the brakes. There are two kinds of brakes: ⑴ 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. ⑵ elbow 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.

Chair seat

Its high, deep and wide 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.

Cushions

In order to avoid pressure sores, it is necessary to pay great attention to the mat, and it is possible to use the eggcrate type or the Roto pad as much as possible. This pad consists of a large plastic with a large number of papillary plastic hollow columns with a diameter of about 5 cm. Are soft and easy to move, the patient after sitting on the pressure into a large number of pressure points, and the patient a little move, the pressure point with the nipple movement and change, so you can constantly change the pressure point, to avoid the same oppression Parts caused by pressure sores. If there is no such mat, you need to use layer foam, the thickness should be 10cm, the upper 0.5cm thick high-density poly (polyvinyl chloride) foam, the lower density of the same nature of plastic, high The density of those who support strong, medium and soft and comfortable. In the sitting position, the ischial tuberculosis pressure is very large, often beyond the normal capillary pressure of 1 to 16 times, easy to form a pressure ulcer. In order to avoid the pressure here is too large, often in the corresponding place on the mat to dig a piece, so that the ischial tubercles overhead, digging in front of the calcaneal nodules should be 2.5cm before the lateral side of the nodules should be 2.5cm, Depth of 7.5cm or so, dug after the mat was concave shape, the gap in the post, if the use of the mat with the incision, can be very effective to prevent the production of pressure sores.

Foot and leg care

Legs can be crossed on both sides, or both sides of the separate, both of which are used to be able 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.

Backrest

The backrest is tall and sloping and can not be tilted. 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.

Armrest or arm support

Generally higher than the seat seat 22.5 ~ 25cm, some arm can adjust the height. But also in the arm on the shelf on the board (lap board), for reading, dining.

Skirt (net)

According to different users, can choose to protect the skirt, skirt net, to prevent the user's skirt or clothes into the wheel.

Wheelchair size

The most important consideration when choosing a wheelchair is the size of a wheelchair. The main parts of the wheelchair who bear the weight of the hip around the sciatica around the femur, around the fossa and around the scapula. The size of the wheelchair, especially the width of the seat, the depth of the back and the height of the backrest and the foot pedal to the cushion is appropriate, will make the passengers involved in the blood of the affected parts of the affected, and skin friction, and even pressure sores. In addition, consider the safety of patients, the ability to operate, the weight of the wheelchair, the use of location, appearance and other issues.

Note the problem

⑴ seat width: measuring the distance between the two hips or between the two shares, plus 5cm that is sitting on both sides after each have a gap of 2.5cm. The seat is too narrow, the upper and lower wheelchair more difficult buttocks and thighs are oppressed; seat is too wide is not easy to sit tight, wheelchair is not convenient to operate, easy to fatigue limbs, access to the door is also difficult.

⑵ seat length: measure the distance between the buttocks to the calf gastrocnemius after sitting down, the measurement results by 6 .5cm. If the seat is too short, the weight will mainly fall on the ischium, easily lead to excessive local pressure; if the seat is too long will suppress the popliteal fossa local blood circulation, and easy to stimulate the skin. For patients with shorter thighs or hip, knee flexion contract, the use of short seats is better.

⑶ seat height: measure the distance when the heel (or heel) to the popliteal fossa distance, plus 4cm, placed in the pedal, the board at least 5cm from the ground. Sitting too high, the wheelchair can not be at the table; seat is too low, the ischium bear the weight is too large.

⑷ cushion for comfortable and prevent bed sores, wheelchair chairs should sit on the cushion. Common cushion with foam rubber pad (5 ~ 10cm thick) or gel pad. To prevent the seat subsidence can be placed in the cushion a 0.6cm thick plywood.

⑸ * back height: * back higher, more stable, * lower back, upper body and upper limb activities are greater. Low back: measure the distance from the sitting surface to the armpit (arm or arm forward), reduce the result by 10cm. High back: measure the actual height of the sitting surface to the shoulder or posterior occipital.

⑹ handrail height: sit down, the upper arm vertical, forearm flat on the armrest, measuring the chair to the forearm of the lower edge of the height, plus 2.5cm. Appropriate armrest height helps to maintain the correct body posture and balance, and can place the upper limb in a comfortable position. Handrail is too high, the upper arm was forced to lift, susceptible to fatigue. Handrails are too low, you need to lean forward to maintain balance, not only easy to fatigue, can also affect the breathing.

⑺ Wheelchair Other accessories: designed to meet the needs of special patients, such as increasing the friction surface of the handle, the box extension, the shock device, the armrest installation arm support, or the convenience of the patient to eat, write the wheelchair table
