AI Technical Summary

Technical Problem

In the use of existing rehabilitation devices for thoracic surgery nursing, the spring tension is uneven, causing patients to feel inconsistent force, which affects their motivation and concentration during exercise, and reduces the comfort and continuity of rehabilitation training.

Method used

The design combines springs and dampers. By rotating the screw to adjust the position of the slider, the friction between the roller and the slide rail is changed, providing constant resistance and ensuring resistance stability during training. The combination of slider, spring, damper and roller achieves constant muscle stimulation.

Benefits of technology

It provides stable and continuous muscle stimulation, improves the effectiveness and quality of rehabilitation training, ensures the consistency and stability of muscle training, and enhances the rehabilitation training effect for patients.

Abstract

The rehabilitation device comprises a bottom plate, two supports are movably connected to the upper surface of the bottom plate, a sliding rail is fixedly connected to the upper surfaces of the two supports, a first sliding block is slidably connected to the inner surface of the sliding rail, a handle is rotatably connected to the upper surface of the first sliding block, a first sliding groove is formed in the sliding rail, and a second sliding groove is formed in the lower surface of the first sliding block. The inner surface of the first sliding groove is in sliding connection with a connecting block, the side surface of the connecting block is fixedly connected with the first sliding block, the connecting block is provided with a second sliding groove, the inner surface of the second sliding groove is in sliding connection with a second sliding block, and the inner surface of the second sliding groove is in threaded connection with a threaded rod in a penetrating mode. The resistance is not changed due to the change of the position of the handle, chest muscles can be subjected to the action of stable and continuous force, the consistency and stability of muscle stimulation are ensured, the effect and quality of rehabilitation training can be improved, and the rehabilitation target can be achieved more accurately.
