Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a foot ring for preventing foot drop in bed for hemiplegic patients. Background Art

[0002] With the development of society, there are more and more patients with hemiplegic foot drop. There are limited choices for fixation methods for hemiplegic foot drop. Currently, external fixator fixation is commonly used. Because external fixator is used for fracture fixation, this external fixation method often leads to foot drop, which causes certain troubles for the rehabilitation of patients in the later stage. In severe cases, it will affect the patient's normal life. Currently, there are limited methods to prevent foot drop. The common ones are to pull the forefoot with elastic tension band, or to penetrate the forefoot with Kirschner wire to keep the ankle dorsiflexion fixed on the external fixator. The above methods have limited effects and may cause secondary injuries to patients. Therefore, how to adopt economical, effective and non-invasive methods and achieve good prevention and treatment effects to develop ankle dorsiflexion system so that patients who have been lying in bed for a long time and cannot move can avoid foot drop during treatment has become a technical problem that has been difficult to solve for a long time.

[0003] For example, a device for preventing foot drop for bedridden patients with publication number 215020968U comprises a wide support band, an installation rope, a connecting block, a connecting tube, a clamping assembly, a foot plate, an antibacterial cloth pad and a rotating assembly, both ends of the wide support band are connected and installed with the installation rope, one end of the installation rope is connected and installed with the connecting block, and the outer side of the connecting block is clamped and installed with the connecting tube, the outer side of the connecting tube is provided with a clamping assembly, both ends of the wide support band are sleeved and installed with foot plates, and the top end surface of the foot plate is fitted with an antibacterial cloth pad; the device for preventing foot drop for bedridden patients has a simple structure, a small size and is easy to install; when in use, it can achieve good prevention and treatment effects by adopting an economical, effective and non-invasive method, and is convenient for patients to dorsiflex their ankle joints, so that patients who have been lying in bed for a long time and cannot move can effectively avoid foot drop during treatment.

[0004] The above patent proposes that the existing foot rings for preventing foot drop in bed for hemiplegic patients are usually devices for preventing foot drop in bed for long-term patients. They have a simple structure, a small size, and are easy to install, but are not convenient for patient training and rehabilitation, which reduces the practicality of the device and is not convenient for adjusting the size of the foot ring. Therefore, the utility model provides a foot ring for preventing foot drop in bed for hemiplegic patients. Utility Model Content
