Description

Technical Field

[0001] The invention belongs to the technical field of restraint tools, in particular to a leg restraint for preventing knee joint bending. Background Art

[0002] In medical care, the use of leg restraints is a common medical treatment for patients who need to restrict lower limb activity to prevent knee flexion, such as postoperative rehabilitation, fracture treatment, muscle spasms caused by neurological diseases, etc. However, the design of traditional leg restraints often focuses on the fixation effect, but ignores the comfort and safety of patients when wearing them for a long time, especially the function of preventing strangulation.

[0003] After searching, in a leg restraint belt with announcement number CN218075396U, the utility model relates to a leg restraint belt, including a seat body and two restraint components, the two restraint components are arranged on the seat body in sequence, the restraint component includes a support plate, a plurality of restraint belt bodies and a plurality of fixing units, the support plate is fixedly connected to the seat body and is located on the outside of the seat body, the support plate has a plurality of first grooves and a plurality of second grooves, one ends of the plurality of restraint belt bodies are fixedly connected to the support plate and are respectively located on the inner walls of the corresponding first grooves, and the other ends of the plurality of restraint belt bodies are respectively adapted to the corresponding second grooves.

[0004] The above-mentioned leg restraint belt has too many restraint belt bodies, which can fully restrain the patient's legs and restrain the patient's legs on the support board, making it impossible for them to bend and move. At the same time, multiple restraint belt bodies make the contact area with the patient larger, reducing the situation of strangulation, which is more suitable for restraining psychiatric patients, so as to facilitate doctors to examine. However, there are still some problems in specific use:

[0005] When in use, the above-mentioned leg restraint can only fix the patient's legs at a single angle and cannot adapt to the limited fixation of other postures of the patient's legs, resulting in its low practicality; the above-mentioned leg restraint directly binds the patient's legs with straps, although it can achieve the function of binding and fixing, but the narrow straps are tied around the patient's legs, and long-term compression can easily cause compressive injuries to the patient.

[0006] Therefore, in view of the above problem, a leg restraint for preventing knee joint bending is proposed. Summary of the invention

[0007] 1. Technical issues to be resolved

[0008] In view of the shortcomings of the prior art, the present invention provides a leg restraint that prevents knee joint bending, which solves the problem that the existing leg restraint belt has a relatively single fixed posture for the patient's legs when in use, and the problem that the existing leg restraint belt is prone to cause pressure injuries to the patient when restraining the patient's legs.

The micro air pump 15 in the restraint component can be controlled by an external controller to inflate and deflate the airbag cushions therein. When the airbag cushions are inflated, they will clamp the patient's legs to achieve the operation of fixing the device and the patient's legs. During use, multiple airbag cushions will be alternately inflated and then deflated by the micro air pump 15, massaging the patient's legs and helping the patient's legs with blood circulation.
