A hemostatic device for trunk bleeding

Abstract

The invention relates to a hemostatic device for trunk bleeding, which comprises a hemostatic block, an inflatable tube, an inflatable connector and a pressure regulating component. The hemostatic block includes an inflatable cavity and a hollow around the center of the inflatable cavity; the inflatable The chamber communicates with one end of the inflatable tube; the other end of the inflatable tube communicates with one end of the inflatable joint; the other end of the inflatable joint communicates with the pressure regulating part; The above-mentioned inflatable cavity is filled with gas, and after the gas enters the inflatable cavity, the inflatable cavity expands toward the hollow part, so that the skin tissue on both sides of the wound pressed under the hollow part moves closer to the middle; at the same time, the inflatable cavity also faces toward the wound perpendicular to the wound. The direction of expansion to help stop bleeding; the pressure regulating part is also used to automatically drive the pressure regulating part to stop filling the inflatable chamber when the air pressure inside the inflatable chamber reaches a predetermined value.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a hemostatic device for trunk bleeding. Background technique [0002] The torso of the human body is not easy to bandage the wound caused by surgery or accidental injury. In the prior art, the wound is usually covered with gauze, which needs to be fixed in place, and the gauze is pressed tightly on the wound with medical tape. However, there are many problems in this method in the prior art, such as: the medical adhesive tape itself cannot apply enough pressure to the wound, and cannot achieve a sufficient hemostatic effect. [0003] In addition, the field hopes that the pressure applied to the wound should not be too large or too small. If the pressure is too high, it will cause unnecessary damage to the patient's wound, and if the pressure is too small, it will not be able to effectively stop bleeding. The prior art cannot realize the adjustment and controllabilit...

However, there are many problems in this method in the prior art, such as: the medical tape itself cannot apply enough pressure to the wound, and cannot achieve sufficient hemostatic effect

[0003] In addition, the field hopes that the pressure applied to the wound should not be too large or too small. Too much pressure will cause unnecessary damage to the patient's wound, and too little pressure will not be able to effectively stop bleeding.

The existing technology can not achieve this kind of pressure regulation and controllable
