Description

Medical crutch convenient to put to side face of bearing object

Technical Field

The utility model relates to a crutch, in particular to a medical crutch which is convenient to put on the side surface of a bearing object.

Background

With the increasing number of the elderly, the life of the elderly is also getting more and more attention from the public.

When a person enters the elderly, the body functions and metabolism are gradually reduced, and the actions become inconvenient, so that many elderly people can use a crutch, which is a traditional and practical device, to help the person walk and get up.

The disadvantages of the above-mentioned techniques are:

1. when the crutch is not used, a patient can lean against the crutch on the wall surface, but the crutch leaned against the wall surface is extremely easy to slip on the ground, and when the crutch is used, the patient needs to bend over to pick up the crutch which is fallen on the ground, and the crutch is inconvenient to pick up due to poor body functions of the patient.

2. After the crutch is fallen on the ground, a patient can usually help medical staff or family members to pick up the crutch and then submit the crutch to the patient, but the family members cannot accompany the patient at any time, the work of the medical staff is busy, the patient cannot be helped to pick up the crutch in time, and the work intensity of the medical staff is increased; when a passer-by passes by the crutch, the passer-by is also easy to stumble over the crutch and hurt.

The chinese patent of CN215779652U, published in year 2022, month 11, discloses a fixing device for a medical crutch, which comprises a fixing plate and a controller, wherein the fixing plate is provided with an upper clamp, a second sliding groove and a lower clamp, one end of the second sliding groove, which is away from the lower clamp, is provided with a spring, two ends of the spring are respectively connected with the second sliding groove and the upper clamp, the upper clamp moves in the second sliding groove, a clamping opening is arranged between the upper clamp and the lower clamp, the controller is provided with a first sliding groove and a control handle, one end of the control handle moves in the first sliding groove, the other end of the control handle is provided with a pull rope, two ends of the pull rope are respectively connected with the control handle and the upper clamp, when the crutch is not used, the control handle moves upwards, the pull rope drives the upper clamp to move along with the control handle in the same direction, the spring is compressed, the clamping opening between the upper clamp and the lower clamp is enlarged, the bed board is placed in the clamping opening, then the control handle is released, the spring is reset, the clamping opening between the upper clamp and the lower clamp is reduced, the upper clamp faces the bed board, so that the crutch body is fixed on the ground in a vertical state, and the crutch body is prevented from falling down on the ground. Although the utility model solves the technical problems, the utility model still has the following defects:

1. the fixing device can only fix the crutch on the transverse plate of the bearing object and can not be fixed on the vertical plate of the bearing object.

2. When the clamping opening between the upper clamp and the lower clamp is opened, a patient holds the handle by hands, and the control handle is pushed upwards by thumb forcefully, so that the control handle drives the upper clamp to move upwards through the pull rope, and for a patient with smaller palm, the thumb is difficult to reach the control handle at the lower end of the first chute, and force is not conveniently applied.
