Description

Household hand function training instrument

Technical Field

The invention relates to the technical field of finger exercise devices, in particular to a household hand function training instrument.

Background

In modern society, the incidence of cardiovascular and cerebrovascular diseases is increasing year by year. In China, stroke becomes a main problem which seriously harms the life and health of middle-aged and elderly people at present, and the incidence, the death rate and the disability rate of the stroke are high. After stroke patients suffer from diseases, most of the stroke patients leave limb dysfunction with different degrees, the life, work and study of the stroke patients are seriously affected, and meanwhile, heavy burden is brought to families and society. The hand dysfunction is more difficult to recover than the lower limb dysfunction because the hand function is more delicate than the lower limb function, and the improvement of the hand dysfunction is very significant for improving the self-ability and the living ability of the patient in the rehabilitation treatment process.

The existing hand function training equipment, traditional grip ball/spring-grip and other simple fitness equipment are used for actively training a user who does not completely lose hand functions by wearing the grip equipment according to a training method of a rehabilitation teacher, so that the training purpose is achieved. However, for such products, the training mode of the user is not targeted, the requirement of the passively trained user cannot be effectively met, and in addition, the hand shape change monitoring function is not available.

Patent 201610835116.6 discloses a finger function rehabilitation training device, which can drive the fingers of a patient to perform rehabilitation training movement and adjust the movement amplitude of the proximal phalanx and the middle phalanx and the distal phalanx of the fingers to adapt to the use of patients with various hand types.

The training system has the disadvantages that ① adopts a rigid device, has the defects of complex structure, high price, limited degree of freedom and the like, has a single ② training mode, is only suitable for the requirement of passive training of patients in the early rehabilitation stage, and cannot meet the requirements of assisted training of patients with 0-2-level muscle strength and active training of patients with 3-level muscle strength.

Patent 201510220120.7 a pneumatic type rehabilitation device for hand function intelligent training, the device can carry out the rehabilitation training to patient's hand dysfunction, and the patient can use the device to carry out the helping hand and the initiative training of finger, wrist in training process, can not cause mechanical damage to the user, is diseases such as cerebral apoplexy, cardiovascular and cerebrovascular or hand joint wound as the equipment commonly used of rehabilitation training.

However, this device is not able to satisfy the power requirements of passive training and assisted training of each finger joint by the movement of driving a single finger or a combined finger with the same air pressure during assisted movement. Moreover, each joint of the finger can be trained only by adjusting the finger adhesive button and fixing a certain joint to drive other joints of the whole finger, so that other joints of the finger are easy to be injured.

Therefore, it is desirable to provide a new home-use hand function training device to solve the above problems in the prior art.
