Description

Wheelchair for hemiplegic patients

Technical Field

The utility model belongs to the technical field of medical care apparatus technique and specifically relates to a make things convenient for wheelchair that hemiplegia patient used.

Background

According to survey and display, more than 250 million new patients with cerebral apoplexy exist in China every year, hemiplegia is one of the common sequelae of patients after cerebral apoplexy, researches indicate that 76% of patients with cerebral apoplexy have dyskinesia to cause difficulty in walking and greatly influence the life of the patients, and the wheelchair serving as a daily transportation tool of the patients with hemiplegia can not only enable the patients to finish self-care of daily life, but also participate in social activities and daily simple housework through the wheelchair, so that the confidence of the patients is greatly enhanced, and the patients can return to the society in a true sense. The existing wheelchair for the hemiplegic patients is provided with a unilateral driving wheel or an electric wheelchair, the unilateral driving wheelchair is not beneficial to the training of the daily living and moving ability of the affected limb, and the electric wheelchair is relatively expensive and high in cost and is difficult for some patients to bear; meanwhile, charging is needed, and the procedure is complicated. Most patients choose a relatively inexpensive common wheelchair, as shown in figure 1. Fig. 2 and 3. However, because the hand brake handle of the ordinary wheelchair is shorter, the length of the hand brake of the wheelchair on the market at present is 8 cm-11.5 cm, and a fixed protective belt for preventing hand slippage is not provided, as shown in fig. 2; the hemiplegic patient has poor strength of most muscles of the upper limb on the hemiplegic side, the wrist side is bent and deformed, the grip is poor, a fixing protective belt is not used when the hemiplegic patient is used, the hemiplegic patient is not firmly held by the hand and is easy to slip, the hand on the affected side is inconvenient to use or cannot use a parking hand brake, the functional exercise of the upper limb on the affected side is indirectly influenced, and the exercise confidence of the patient is also influenced; meanwhile, after the safety belt of the common wheelchair is buckled, no warning sound is generated when the safety belt is unbuckled, so that the function of reminding family members or accompanying nursing cannot be achieved, many examples of falling caused by unstable standing due to insufficient muscle strength of lower limbs after the safety belt is unbuckled by many hemiplegia patients who return to the family clinically or return to the family are provided, skin trauma of light patients, fracture of heavy patients and craniocerebral injury are even endangered, and great social problems and safety problems are caused. Furthermore, the lower limbs of the hemiplegic patient are mostly in a extensor spasm mode, which is characterized in that the hip joints are extended outwards, retracted inwards, rotated inwards, the knee joints are over-extended, the ankle joints are bent inwards and inverted inwards, and when the patient is in a flaccid paralysis stage or a spasm stage, the muscle strength of the lower limbs is insufficient or the tension is too high, the two lower limbs are difficult to bend and bend at the hip and knee positions and are arranged on the pedals, usually the lower limbs droop and swing at will, meanwhile, the feet cannot be arranged on the pedals, and the pedals of the existing wheelchair, as shown in fig. 3, cannot realize effective support of the feet and the shanks, so that the danger that the feet and the lower limbs are easily; and the shank belt of the existing wheelchair is not suitable for the hemiplegic patient, firstly, the muscle strength of the early lower limb of the hemiplegic patient is poor, the muscle tension is gradually increased along with the progress of the illness state, the lower limb is in spasm and deformity, the lower limb can not be independently attached to the shank belt, the support effect of the shank belt on the affected leg is not ideal, and the improvement is needed. Simultaneously, the patient sits on the wheelchair for a long time, and the cushion texture is harder relatively, because hemiplegia patient's autonomic activity obstacle, can not decompress by oneself, when the pressurized tissue lasts the pressurized and exceeds certain time, arouses that the tissue is ischemic, forms pressure ulcer, increases patient's misery and economic burden, and serious person arouses septicemia critical patient life.
