Elbow joint function rehabilitation device with medicine applying function

Abstract

The invention relates to the field of auxiliary medical apparatus and instruments, and aims to provide an elbow joint function rehabilitation device with a medicine applying function. The technical scheme includes that the elbow joint function rehabilitation device comprises a base, an upper arm fixing plate and a forearm fixing plate are arranged on the base, a connection lug is arranged on the back of each of the forearm fixing plate and the upper arm fixing plate, and the forearm fixing plate and the upper arm fixing plate are hinged to the base through hinge shafts arranged at the positions of the connection lugs. A first connection plate is arranged on the back side of an end portion, close to a gap, of the forearm fixing plate. A driving mechanism is arranged on the base and comprises a linear electric motor and a flexible connection component. The flexible connection component comprises a spiral spring and a short rod, one end of the short rod is hinged to an output end of the linear electric motor, the other end of the short rod is fixedly connected with one end of the spiral spring, and the other end of the spiral spring is fixedly connected with the first connection plate. The elbow joint function rehabilitation device is more adaptive to rehabilitation requirements in early rehabilitation stage and has the advantages that injury to the elbow joint can be avoided, and rehabilitation effect is improved greatly.

Description

technical field [0001] The invention relates to the field of auxiliary medical devices, in particular to an elbow joint function rehabilitation device with a drug application function. Background technique [0002] The elbow joint is an important functional joint of the upper limb. Elbow joint or upper extremity surgery, such as orthopedic cross-joint surgery or neurosurgery peripheral nerve repair surgery, requires external fixation of the elbow joint after the operation, but after the fixation is completed, the elbow is often left unable to bend, stretch or flexibly. Sequelae of bent-angle foot. At present, the conventional method for this sequela is to achieve the purpose of gradual rehabilitation by artificially assisting and repeating the upper limbs of the patient. This method is time-consuming and labor-intensive, and the labor intensity is too high for the nursing staff. For this reason, there have been auxiliary devices aimed at the recovery of elbow joint functio...

AI Technical Summary

Problems solved by technology

[0003] However, there are still many defects in this type of device. For example, in the existing rehabilitation aids, since the big arm plate is fixed and the driving force for driving the forearm plate is too mechanized, the forearm plate is rigid during bending. Too large, easy to cause damage to the elbow joint

Especially for patients in the early stage of rehabilitation, the amount of bending of the elbow joint should not be too large, and the forearm plate of the existing rehabilitation aid device lacks a bending buffer during the bending process (the forearm plate bends as much as the motor rotates), resulting in Not applicable in the early stages of recovery

At the same time, in the process of recovering the function of the elbow joint, it is often necessary to cooperate with certain drugs for external application to achieve better results, and there is no similar device in the prior art.
