How to buy a wheelchair? What kind of wheelchair buy good? Buy wheelchairs should pay attention to what? Said that the first inventor of the original wheelchair Zhuge Liang ah! The first design three wheel wheelchair wheelchairs are an important tool for rehabilitation, it is not only physical injury disabled person of means of transport, more importantly, to make them wheelchair by means of physical exercise and participate in social activities. Ordinary wheelchairs generally consists of wheelchair frame, wheels, brakes and seat against four parts. 1. Large wheel bearing major weight. Diameter wheels have 51,56,61,66cm several species. Apart from a few environmental requirements and the tire with a solid, multi-pneumatic tires. 2. Small wheel diameter 12,15,18,20cm several large diameter easy to cross the small ferry obstacles and special carpets. However, too large a diameter so that the entire wheelchair becomes larger footprint, reduced mobility. Normal small round before the big wheel, but in those with paraplegia wheelchair, often after the small wheel on the big wheel. The operation should be noted that the direction of Ferry's best big wheel with vertical, or easy dumping. Hand wheels for wheelchair unique to the rim diameter is generally larger than the small 5cm. Hemiplegia with one hand while driving, coupled with a smaller diameter are to choose from. Hand wheels generally directly driven by the patient, if dysfunction, is easy to drive, may have altered the following way: (1) increase in the surface of the rubber hand wheels, etc. in order to increase frictions force. (2) along the rim four weeks to increase hand pushes the knob (knob). Push the following: â‘ level push to. C5 spinal cord injury when used. Consequently, the biceps sound, push the upper hand on, by the elbow force can advance carts. Without pushing the level, you can not push. â‘¡ Push the vertical. Used for rheumatoid arthritis hand shoulder joint mobility. So when you can not push the level of use. â‘¢ bold push to. Patients for finger movements severely restricted and difficult to make a fist, and also applies to osteoarthritis, heart disease or elderly patients. Its seat height and depth, width depends on the patient's body, the texture of the material also depends on the disease. Usually deep 41,43cm, width 40,46cm, high 45,50cm. By back to back has height and tilt and non-tilt points. If the patient's torso better balance and control, the choice of low-back wheelchair, so that patients have a greater activity. On the other hand, to use high back wheelchair. The selection of the wheelchair most important factor to consider is the size of the wheelchair. Wheelchair who bear the weight of the main part of the ischial tuberosity around the hips, around the femur, Elaine nest around and around the shoulder blades. Wheelchair dimensions, especially the seat width, depth and backrest height and distance from the pedals to the seat cushion is appropriate, the relevant rider will make efforts to affected parts of the blood circulation and skin abrasion occurs, even pressure sores. Also, consider the patient's safety, operational capacity, weight wheelchair, place of use, appearance, and other issues.

Also, consider the patient's safety, operational capacity, weight wheelchair, place of use, appearance, and other issues. Selection attention: (1) Seat Width: Measure the distance between the two buttocks when shares or two sit down, sit down later in Canada that is 5cm 2.5cm on each side of the gap. The seat is too narrow, and down the wheelchair more difficult to organize buttocks and thighs are oppressed; the seat is too wide is not easy to sit tight, inconvenient to manipulate wheelchairs, two limbs, fatigue, out the door too difficult. (2) Seat length: buttocks to sit down when measuring the horizontal distance between the gastrocnemius, the measurement result minus 6.5cm. If the seat is too short, the weight will fall mainly on the ischial, could easily lead to excessive pressure on the local Yi; if the seat is too long will oppress the popliteal fossa affect local blood circulation, and easy to stimulate the skin. Shorter thigh or hip, knee flexion contracture patients, the use of short seat better. (3) Seat height: Measure sit down heel (or heels) to the distance from the popliteal fossa, plus 4cm, when placing the foot pedal, the board off the ground at least 5cm. The seat is too high, a wheelchair can not enter the table; the seat is too low, the ischial bear excessive weight. (4) cushions for comfort and to prevent bedsores, wheelchairs sit chair cushion should be placed. Common cushion foam rubber pad (5 ~ 10cm thick) or gel pads. In order to prevent subsidence can be delegated a seat 0.6cm thick plywood in cushion. (5) Back height: back higher, more stable, lower back, upper body and upper limb activities will be. Low * Back: take the measurement surface distance to the armpit (the arm or arms forward Stretch), the result of this subtraction 10cm. High * Back: sit face to measure the actual height of the shoulder or occipital. (6) The armrest height: When you sit down, upper arm vertical, forearms flat on the armrest, measuring the seat to the height of the lower edge of the forearm, plus 2.5cm. Appropriate armrest height helps maintain proper posture and balance, and make the upper limb is placed in a comfortable position. Armrest is too high, the upper arm forced swarmed susceptible to fatigue. Armrest is too low, you will need to maintain the balance of the upper body leaning forward, not only fatigue, may also affect breathing. (7) wheelchairs Other aid: in order to meet the needs of a particular patient and design, such as increasing the handle friction surface, car cassette extends shock device, handrail mounting arm bracket, or the convenience of patients eat, write wheelchair tables and the like.
