Description

Single-leg auxiliary moving medical support capable of controlling single moving distance

Technical Field

The invention relates to the technical field of medical equipment, in particular to a single-leg auxiliary moving medical support capable of controlling a single moving distance.

Background

The existing body injuries, such as leg injuries and other patients, can be bedridden for a long time, chronic diseases such as pneumonia, bedsore and the like can be easily caused, frequent activities are needed, all parts of the body need to be moved during rehabilitation, particularly, when the patient cannot stand, in order to prevent all joints and muscles of the body from being stiff and powerless due to incapability of moving, the patient needs to be moved all the time, the existing mode is to move through a crutch of the patient, then recover the joint through the gradual movement of the leg, and the effect is limited.

So when the single shank of the patient is injured and can't touch the ground and walk appearing, just need to provide supplementary walking instrument to injured leg, present shank assists mobile device, through the tire that the below set up, drives the shank and removes, but it can't realize fine control displacement distance, because the shank removes, the distance of taking a step the leg is limited, so when unable fine control shank assists mobile device, the condition that the leg distance of just appearing uncontrollably leads to the patient to fall down easily.

Therefore, in the prior art, in order to provide an auxiliary moving device for a leg, the leg moving medical auxiliary device of application number "201520727326.4" includes two supporting side plates, the outer walls of the two supporting side plates are fixed with clamping portions, the two ends of a front elastic belt are fixed at the front portions of the two clamping portions, the two ends of a rear elastic belt are fixed at the rear portions of the two clamping portions, the lower portions of the two supporting side plates are provided with connecting portions extending backwards, the two connecting portions are respectively fixed at the two ends of a connecting beam, a rotating shaft is hinged in the two connecting portions, the two ends of the rotating shaft extend out of the connecting portions and are fixed with rollers, a driving motor and a control housing are fixed on the connecting beam, a transmission bevel gear is fixed on an output shaft of the driving motor, a bevel gear is fixed at the middle portion of the rotating shaft. It can be installed on the leg that patient is injured, rotates through control roller, realizes removing to help patient to remove, improve recovered speed and effect.

Although the leg movement medical assistance device can assist the movement of the leg, the device still has the following obvious defects in the use process: adopt motor control gyro wheel to rotate, realize removing, although can control gyro wheel rotation distance, the mode of adopting the motor, on the one hand need provide the electric energy, runs away from with energy-concerving and environment-protective, and on the other hand motor drive gyro wheel rotates, and the condition such as motor trouble appears easily, then needs to maintain, and is very troublesome.
