Description

Intermittent inflation pressurizing device for deep vein thrombosis prevention Technical Field The invention relates to the technical field of pressurizing devices, in particular to an intermittent inflation pressurizing device for deep vein thrombosis prevention. Background The intermittent inflation pressurization device (IPC) is non-invasive physical medical equipment for preventing Deep Vein Thrombosis (DVT), and has the core functions of simulating the muscle pumping action of a human body through periodic inflation and deflation, promoting venous blood reflux and reducing the risk of thrombosis. The inflatable cuff is mainly composed of an inflatable cuff (parts of a lower limb, an upper limb and the like are adapted to), an air pressure control host and a connecting pipeline, and is widely applied to high-risk groups such as postoperative patients and long-term bedridden patients; after 10-15 seconds of maintenance, the air is rapidly released, allowing the vasodilation to complete a cycle every 1-2 minutes. The device does not need the initiative cooperation of the patient, can make up the defect of insufficient muscle activity of bedridden patients, enhances the activity of a fibrinolytic system, double prevents thrombus from the aspect of mechanics and biology, has high safety and fewer complications, is an important auxiliary means for preventing medicines, and the intermittent inflation pressurizing device for deep vein thrombosis prevention needs to be adapted to the limb circumference and body position of different patients, and simultaneously needs to ensure the pressurizing accuracy, wearing comfort and long-term use safety, and promotes vein reflux by simulating the muscle pump effect.
