Hemostatic device for vascular surgery

Abstract

The invention provides a hemostatic device for vascular surgery. The adopted technical solution is that there is a waterproof layer inside the outer layer, a liquid storage bag and an air bag are arranged between the waterproof layer and the inner top surface of the outer layer, and a soft bag is arranged on the liquid storage bag. Tubes and hoses pass through the outer layer and are connected to the bottom of the waterproof layer. There is a pressure sensor on the top of the fluid storage bag and a heating wire inside; there is a gauze fixing block at the inner bottom of the outer layer; there is a control panel and a zipper on the outer layer. By adopting the zipper structure, it is convenient to separate the gauze from the waterproof layer and facilitate the replacement of the gauze; by using the pressure sensor, the pressure of the airbag on the wound can be visualized to avoid secondary damage to the wound caused by excessive pressure; Appropriate heating can increase the activity of coagulation factors and accelerate hemostasis; by using the CaCl2 solution contained in the fluid storage bag to moisten the gauze, Ca2+ can be used to accelerate blood coagulation and improve the hemostasis efficiency; Used to guide above the gauze at the wound site to improve hemostasis.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a hemostatic device for vascular surgery. Background technique [0002] During surgical operations, it is inevitable that the blood vessels will bleed. If the blood vessels cannot be treated in time, infection will easily occur, or excessive bleeding can lead to coma, convulsions, yang collapse and other serious diseases. Emergency medical personnel use bandaging bandages to stop the bleeding of some bleeding traumas, but a lot of bleeding will still seep into the bandages, which cannot effectively stop the bleeding. They also use latex bands to tighten the bleeding upper part of the wound to stop the bleeding, which will make the patient It is very uncomfortable, and it is prone to the undesirable phenomenon of tissue necrosis caused by excessive tightening. Most of the hemostatic devices currently on the market have complex structures of fixed parts, and the steps of...
