A kind of knee joint post-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 post-training device for the recovery of knee joint movement functions. Background technique [0002] After knee or lower extremity surgery, the patient cannot exercise for a long time, resulting in contractures and stiffness of the knee joint cavity, muscle ligaments, etc., which affects the range of motion of the knee joint and brings great inconvenience to the patient's work and life. Usually, there are two main methods for the recovery of knee joint function: one is the surgical method, which can only deal with the adhesion and contracture of some tissues. Even if the knee joint function can be restored, if the recovery exercise cannot be performed in time after the operation It is very likely to re-adhesion, resulting in secondary stiffness; the second method is to perform rehabilitation training on the knee joint, by applying external force to passively move the k...

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 CN 104800046 A discloses a knee joint flexion trainer for knee joint rehabilitation training. It needs to fix the thigh and calf on the training device. By changing the bending degree of the device, the knee joint can be passively trained with the device. However, the degree to which patients can autonomously control the amount and intensity of exercise is limited.
