Pneumatic automatic hemostasis equipment and pneumatic automatic hemostasis method

Abstract

The invention discloses pneumatic automatic hemostasis equipment and a pneumatic automatic hemostasis method. The method includes the steps of starting a timer to compute hemostasis time of a tourniquet acting on a wound surface; controlling a miniature air pump to suck in air via air inlet holes to inflate the tourniquet and acquiring an air pressure value in the tourniquet by an air pressure sensor; when the air pressure value is smaller than a first preset value, continuing controlling the miniature air pump to suck in the air via the air inlet holes to inflate the tourniquet; when the air pressure value is larger than a second preset value, controlling the miniature air pump to deflate the tourniquet via air outlet holes; when the air pressure value is between the first preset value and the second preset value, judging whether the hemostasis time reaches preset time or not; when the hemostasis time reaches the preset time, controlling a loudspeaker to play voice information to inform medical personnel of checking hemostasis conditions of the wound surface. The pneumatic automatic hemostasis equipment and the pneumatic automatic hemostasis method have the advantages that the problems of poor hemostatic effects caused by too high or too low hemostasis pressure of the tourniquet acting on the wound surface and wound tissue necrosis caused by long-time continuous vascular compression can be avoided effectively.

Description

Technical field [0001] The invention relates to the field of life emergency rescue, in particular to a pneumatic automatic hemostatic equipment and method. Background technique [0002] Tourniquet is a simple and effective hemostatic device used in the first aid of massive bleeding in extremities. It blocks blood flow by compressing blood vessels to achieve the purpose of hemostasis. Tourniquets are widely used in general surgery to stop bleeding from arteriovenous trauma or surgical limb surgery. The common tourniquets are mainly rubber tube tourniquets, snap-type tourniquets and inflatable tourniquets. The inflatable tourniquets currently appearing are all capsule tourniquets, which are composed of tourniquets with internal airbags. Although it can stop bleeding, the whole tourniquet is thicker because the airbags are wrapped in the tourniquet and need to be used. The airbag of the hemostatic belt is inflated as a whole, so the inflation time is long and it is not convenient f...

Problems solved by technology

[0004] The main purpose of the present invention is to provide a pneumatic automatic hemostasis device and method, aiming to solve the problem of poor hemostatic effect caused by excessive or too low hemostatic pressure and the long-term persistence of the tourniquet when the existing tourniquet stops bleeding on the wound surface. The problem of tissue necrosis caused by compression of blood vessels on the wound surface
