Embodiment Construction

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0042] Currently commonly used tourniquet, the method is to apply a pressure higher than blood pressure at the proximal end of the bleeding site (such as placing a tourniquet on the upper arm when the hand is bleeding), so as to achieve the purpose of compressing hemostasis. However, this tourniquet has certain limitations; the pressure of the tourniquet is often set according to clinical experience, generally higher than normal bl...

Abstract

The invention provides a tourniquet based on blood pressure automatic adjustment, and relates to the field of medical instruments. The tourniquet based on blood pressure automatic adjustment comprisesa cuff, a blood pressure measuring device and a control device; an air room is formed in the cuff; the blood pressure measuring device measures blood pressure based on a photoplethysmography method,and the measured blood pressure is output into the control device; the control device controls pumping and discharging of air in the air room based on the measured blood pressure, so that pressure, exerted on the limbs, of the tourniquet is controlled. According to the tourniquet based on blood pressure automatic adjustment, the pressure of the tourniquet can be adjusted based on the blood pressure, and on the premise that the demand for hemostasis is met, compression injuries of the tourniquet on a patient are reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a tourniquet that is automatically adjusted based on blood pressure. Background technique [0002] Tourniquet hemostasis is a simple and effective hemostasis method for emergency treatment of massive bleeding in the extremities. It achieves the purpose of hemostasis by blocking blood vessels by compressing blood vessels. [0003] Currently commonly used tourniquet, the method is to apply a pressure higher than the blood pressure at the proximal end of the bleeding site to achieve the purpose of compressing the hemostasis. [0004] However, this tourniquet has certain limitations; the pressure of the tourniquet is often set according to clinical experience, which is generally higher than normal blood pressure, and the damage caused by the compression is relatively large; moreover, the blood pressure of many patients may not be in the normal range clinically.
