Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical rehabilitation equipment, in particular to a muscle electrical stimulation rehabilitation anti-atrophy device for a limb on a surgical side after cardiovascular intervention. BACKGROUND

[0002] After cardiovascular intervention, the limb on the surgical side of the patient often needs to be immobilized to ensure the healing of the puncture site, but it is easy to cause disuse atrophy and muscle strength decline. Immobilization leads to a sudden decrease in muscle activity, a decrease in muscle fiber protein synthesis, and an acceleration of decomposition. The muscle volume gradually shrinks, especially the lower limb muscle groups such as the calf gastrocnemius muscle and the quadriceps muscle. At the same time, the slow blood flow causes insufficient oxygen and nutrients to the muscles, further exacerbating muscle cell function decline, which manifests as limb weakness and limited range of motion. If not intervened in time, it may develop into permanent muscle weakness, affecting the patient's daily activity ability, and even increasing the risk of complications such as deep vein thrombosis, which adversely affects postoperative rehabilitation progress and quality of life.

[0003] After cardiovascular intervention, a specific instrument outputs a low-frequency pulse current to act on the muscles of the limb on the surgical side, simulates nerve impulses to cause muscle contraction, promotes local blood circulation, maintains muscle activity and tension, and delays or prevents atrophy.

[0004] In the prior art, electrical stimulation is usually achieved by pasting electrode patches on the patient's limbs and then connecting instrument wires to stimulate local muscles. Once the electrode patch is attached, it is difficult to adjust the position flexibly. When stimulation is needed for different muscle groups or different areas of the same muscle, the electrode patch needs to be repeatedly peeled off, which not only is cumbersome to operate, but also may cause skin allergy or damage due to frequent contact with the skin, directly affecting the effect of electrical stimulation. In addition, it cannot be combined with massage movements to promote blood circulation and relieve muscle tension, resulting in insufficient comprehensive effect in improving muscle activity and preventing atrophy, and poor overall user experience.

[0005] Therefore, we propose a muscle electrical stimulation rehabilitation anti-atrophy device for a limb on a surgical side after cardiovascular intervention. SUMMARY
