Hemostasis device for vascular surgery

Abstract

The invention discloses a hemostasis device for a vascular surgery. The technical scheme is that a waterproof layer is arranged in an outer layer, a liquid storage bag and an airbag are arranged between the waterproof layer and the inner top surface of the outer layer, a hose is arranged on the liquid storage bag, the hose penetrates through the outer layer to be connected to the bottom of the waterproof layer, a pressure sensor is arranged above the liquid storage bag, and an electric heating wire is arranged in the liquid storage bag; a gauze fixing block is arranged at the inner bottom of the outer layer; and a control panel and a zipper are arranged on the outer layer. By use of the zipper structure, gauze and the waterproof layer can be separated conveniently, and replacement of the gauze is facilitated; by use of the pressure sensor, the pressure of the airbag to a wound is visual, and secondary injury of overlarge pressure to the wound is avoided; the resistance wire is adoptedto properly heat the wound to improve activity of clotting factors and accelerate hemostasis; a CaCl2 solution contained in the liquid storage bag is used to moisten the gauze, and Ca2+ is used to accelerate blood coagulation and improve the efficiency of hemostasis; and a liquid in the storage bag is more accurately directed to the top of the gauze at the wound through the hose to improve the hemostatic effect.

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...
