Description

Technical Field

[0001] The present invention relates to the technical field of post-operative care for femoral artery puncture, and in particular to a foot activity device. Background Art

[0002] Femoral artery puncture is a technique performed under local anesthesia, where a needle is used to percutaneously puncture the femoral artery, allowing the insertion of a guidewire, catheter, or other device for angiography and interventional procedures. It is commonly used to diagnose and treat various vascular diseases, such as coronary artery disease and peripheral vascular disease. It can also be used to collect arterial blood for tests such as blood gas analysis.

[0003] After surgery, the patient is generally required to straighten the limb on the puncture side and immobilize it for a period of time, usually 6-12 hours, depending on the puncture situation and the doctor's instructions. This is to prevent bleeding or thrombosis at the puncture site and to avoid changes in intravascular pressure caused by limb movement, which could affect the healing of the puncture site.

[0004] However, prolonged immobilization of the legs not only causes discomfort to the patient but also impedes blood circulation and may lead to the formation of blood clots. Therefore, patients can perform appropriate ankle exercises to promote blood circulation and alleviate discomfort. However, when patients independently move their ankles, they tend to move their legs, which is detrimental to the recovery of the puncture site and is difficult for others to assist.
