Knee joint later-period rehabilitation training chair

Abstract

The invention discloses a knee joint later-period rehabilitation training chair which comprises a base, two guide grooves, two lifting devices, a base plate, assisting armrests and a backrest. The two guide grooves are fixed to the upper side face of the base. The left side and the right side of the upper side face of the base are each provided with a row of lead screw fixing holes at equal intervals. Two long slots transversely distributed in parallel are formed in the middle of the upper side face of the base. The guide grooves and the long slots are distributed in a crossed mode. Four corners of the lower side face of the base are each provided with an antiskid leg. Each lifting device comprises a nut type ball screw and a transmission rod. The two lifting devices are connected through the transmission rods. The base plate is located on the base. Insert connection is adopted for the backrest, the two sides of the backrest are provided with metal rods, and the two metal rods penetrate through penetrating holes of the base plate and are inserted in backrest fixing holes in the base. The knee joint later-period rehabilitation training chair has the advantages of being user-friendly in design, simple in structure, easy to operate, low in price and the like and is suitable for a patient who rests at home and has a knee joint bending problem.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a late-stage training device for recovery of knee joint motion function. Background technique [0002] After knee joint or lower limb surgery, the patient cannot move for a long time, resulting in adhesions in the knee joint cavity, contracture and stiffness of muscles and ligaments, etc., which affects the range of motion of the knee joint and brings great inconvenience to the work and life of the patient. Usually, there are two main methods for the recovery of knee joint function: one is surgery, which can only deal with the adhesion and contracture of some tissues. It is very likely to re-adhesive, resulting in secondary stiffness; the second method is to perform rehabilitation training on the knee joint, by applying external force to make the knee joint move passively, through long-term rehabilitation training, the shortened soft tissue can undergo physiological chang...

AI Technical Summary

Problems solved by technology

When training with knee tuck in sitting position, a lot of force needs to be exerted, and the patient is prone to fatigue and it is difficult to persist; when training in kneeling and squatting, the knee joint needs to bear a lot of force, especially for patients with femoral fractures. prone to secondary fractures

[0004] At present, the existing knee joint rehabilitation training devices on the market are expensive, bulky, unsuitable for home use or only suitable for early rehabilitation training of the knee joint, etc.

Chinese patent application CN104800046A discloses a knee joint flexion trainer for knee joint rehabilitation training. It needs to fix the thigh and calf on the training device, and the knee joint can be passively trained with the device by changing the bending degree of the device. However, the patient Limited degree of voluntary control of exercise volume and intensity
