Electric wheelchair purchase skills are very important, the correct purchase will make the legs and feet inconvenient people feel comfortable, electric wheelchair purchase skills is a science, it is also divided into many kinds, next Xiaoyuan elderly mobility scooter Xiaobian take you to understand electric wheelchair purchase skills in detail.

Seat width: Measure the distance between the two hips or two strands when sitting down. Add 5cm, that is, there is a 2.5cm gap on each side after sitting down. The seat is too narrow, which makes it difficult to get in and out of the wheelchair. If the seat is too wide, it is not easy to sit firmly. It is not convenient to maneuver the wheelchair, and the limbs are easy to tire. It is also difficult to enter and exit the door.

Seat length: Measure the horizontal distance between rear buttocks and calf gastrocnemius muscle when sitting, and reduce the measured result by 6.5 cm. If the seat is too short, the weight will mainly fall on the ischium, easy to cause local easy pressure too much; If the seat is too long, it will compress the popliteal fossa and affect the local blood circulation. For patients with short thighs or flexion contracture of hips and knees, it is better to use short seats.

Seat height: Measure the distance between the heel (or heel) and the popliteal socket when sitting, and add 4cm. When placing the foot pedal, the board surface shall be at least 5cm above the ground. The seat is too high for the wheelchair to enter the table; If the seat is too low, the sitting bones bear too much weight.

Cushion For comfort and to prevent bedsores, the chair of the wheelchair should be placed on the cushion. Common cushions are foam rubber pads (5 ~ 10cm thick) or gel pads. A sheet of 0.6cm thick plywood can be placed under the seat cushion to prevent the seat from sinking.

Back height: The higher the back, the more stable, and the lower the back, the greater the movement of the upper body and upper limbs. Low chair back: Measure the distance from the sitting surface to the armpits (one or both arms flat forward) and subtract 10cm from this result. High back: Measure the actual height of the sitting surface to the shoulders or back occipital.

Armrest height: When sitting down, the upper arm is vertical, the forearm is flat on the armrest, measure the height from the chair surface to the lower edge of the forearm, and add 2.5cm. Proper armrest height helps maintain proper body posture and allows the upper limbs to be placed in a comfortable position. Armrest is too high, the upper arm is forced to lift, prone to fatigue. If the armrest is too low, the upper body needs to lean forward to maintain balance, which is not only easy to fatigue, but also can affect breathing.
