Wearable gradient pressure anti-thrombus device

Abstract

The invention discloses a wearable gradient pressure anti-thrombus device and belongs to the field of medical appliances. The wearable gradient pressure anti-thrombus device comprises a control structure and an application structure, wherein the control structure comprises a control structure body, and the control structure body comprises a gas pump, a three-way solenoid valve, a conversion jointand a transition joint; a T-shaped block structure is arranged on the control structure; the application structure comprises a pluggable connecting plate, a coating layer and a gas guide pipe; the pluggable connecting plate is fixedly arranged on the coating layer, and a T-shaped groove matched with the T-shaped block is formed in the pluggable connecting plate; and a gas bag is arranged in the coating layer and is connected with the pluggable connecting plate through the gas guide pipe. The wearable gradient pressure anti-thrombus device disclosed by the invention is capable of preventing thrombosis and reducing the probability of cross infection of patients.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a wearable gradient pressure antithrombotic device. Background technique [0002] Compression therapy refers to a therapy that applies pressure to the limbs to achieve the treatment of diseases. Its working principle is that through passive and uniform massage, with the acceleration of blood circulation, it can accelerate the absorption of metabolic waste, inflammatory factors, and pain-inducing factors in the blood. It can prevent muscle atrophy, prevent muscle atrophy, strengthen the oxygen content of limbs, and help to solve diseases caused by blood circulation disorders. The working mechanism of pressure therapy is to increase the tissue hydrostatic pressure and force the return of venous blood and lymph fluid; at the same time, by increasing the hydrostatic pressure of the interstitial fluid to about five times the normal situation, it can overcome the capillary i...

Problems solved by technology

[0004] However, the existing gradient pressure antithrombotic devices at home and abroad currently have the following defects: 1. The equipment is large in size, the patient must be fixed next to the equipment, the activity space is limited, and the control structure and application structure of the small equipment are integrated. , cannot be disassembled, and the covering layer is shared by many people, which is easy to cause cross infection; 2. The treatment data cannot be stored, and data management and analysis cannot be implemented for the patient's treatment process; 3. There is only one air pump in the air circuit to inflate the entire air bag. , the working time of one inflation cycle is long, which seriously shortens the service life of the equipment; 4. The charging time is long, usually 7 to 8 hours, and the efficiency of the equipment is greatly reduced; 5. The treatment parameters cannot be set independently according to the patient's condition, and cannot be displayed in real time Treatment parameters; 6. The airbag has only one inflatable cavity, which cannot squeeze the limbs uniformly and orderly from the distal end to the proximal end
