A wheelchair armrest

technical field

The utility model belongs to the technical field of rehabilitation devices, in particular to a wheelchair armrest.

Background technique

The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.

Stroke refers to a group of diseases that damage the brain tissue due to the sudden rupture of the blood vessels in the brain or the blockage of the blood vessels to prevent the blood from flowing into the brain.

After a stroke, when the patient sits or stands against gravity in the early stage, subluxation of the shoulder joint will occur, causing the affected arm to hang on the side for too long, and there will be a feeling of falling and pain. This pain can be relieved immediately when the upper limb is passively raised or supported on a table in front of you.

After a patient has a stroke, they need to queue up for examination and rehabilitation treatment frequently during hospitalization. During the process of examination and rehabilitation treatment, the patient cannot walk by himself and can only rely on a wheelchair. Therefore, patients spend a large part of their time in wheelchairs. In a wheelchair, patients can place their arms on the armrests of the wheelchair to relieve pain and shoulder subluxation. The existing wheelchair armrests cannot be adjusted, and the size of the wheelchairs in the hospital is basically the same, and the patients have obvious individual differences. The patient's body size is too large or the body size is too small, which will affect the comfort, and thus have a certain impact on the degree of rehabilitation.

In addition, during the spastic phase of the stroke, muscle tone gradually increases, manifesting as spastic hemiplegia, accompanied by abnormal movement patterns, such as the flexor muscles of the upper limbs being heavier than the extensor muscles, making it impossible for the patient to place the affected limb in a wheelchair. on the armrest.

SUMMARY OF THE INVENTION

In order to solve the technical problems existing in the prior art, the purpose of the present invention is to provide a wheelchair armrest.

In order to solve the above technical problems, the technical scheme of the present utility model is:

A wheelchair armrest comprising:

The beam is used for horizontal installation on the bottom of the wheelchair, and several bolt holes are processed in sequence along the length of the beam;

The telescopic support rod includes a fixed plate, rod 1 and rod 2. The rod is set inside rod 2. Through holes are machined at different heights of rod 1 and rod 2. Bolts are used to connect through holes at different positions to realize telescopic Adjustment of the length of the support rod; the fixing plate is arranged at one end of the telescopic support rod, at least two through holes are machined on the fixing plate, and the fixing plate is fixed on the beam by bolts;

The clamp is installed on the other end of the telescopic support rod;

The bottom of the support plate is provided with a base, one end of the rotating shaft is fixed on the base, and the other end extends into the clamp and is detachably installed in the clamp.

The beneficial effects of the present utility model are:

Several bolt holes are arranged in the length direction of the beam, and the fixing plate of the telescopic support rod can be installed on the bolt holes at different positions of the beam, and then the relative position of the armrest and the wheelchair body can be adjusted to improve the comfort of the patient.

The setting of the telescopic support bar makes the height of the armrest of the wheelchair adjustable to meet the requirements of patients with different heights.

The wheelchair is small, and the body of stroke patients is relatively heavy, so the process of getting into the wheelchair has certain difficulties. The support plate is installed in the clamp through the rotating shaft. When using, the clamp can be loosened first, and the support plate can be rotated to reduce the obstruction of the support plate to the patient. After the patient sits in the wheelchair, the support plate can be rotated to In the horizontal position, the clamp can be tightened to realize the fixation. Makes the process of getting into a wheelchair easier for the patient.
