compression hemostatic device

Abstract

The invention relates to a medical device, especially a compression hemostatic device, which provides a structure with a transparent light path, which can more clearly observe the bleeding condition and more effectively compress and stop bleeding according to the patient's condition, including: a base body; a belt, and its two ends respectively connected to the two ends of the base body to form a ring shape; the pressing mechanism, which is arranged on the inner side of the base body facing the belt, includes a pressing chamber and a pressing piece, and the pressing piece is movable by a movable part The compression cavity is sealed tightly and a transparent lens is arranged at the compression end facing the belt, and the base body is at least partially transparent to form a transparent light path penetrating the base body from the transparent lens; an adjustment mechanism includes an adjustment A chamber and an adjustment member, the adjustment chamber communicates with the compression chamber, the adjustment member movably seals the adjustment chamber with a movable body, the movement of the adjustment member changes the volume of the adjustment chamber and changes the volume of the adjustment chamber through the The compression chamber transmits the pressure to the compression member.

Description

technical field [0001] The invention relates to a medical device, in particular to a compression hemostatic device. Background technique [0002] In the existing compression hemostatic devices, the bleeding point is mostly compressed by an air bag or a pressing plate to achieve the purpose of hemostasis. Such compression hemostatic devices usually require an external gas or liquid source (such as an injection syringe used for a balloon-type compression hemostatic device) to operate, and are connected by medical personnel through a connecting tube. The operation is quite complicated and requires operators to have quite high professionalism experience. Especially when it is necessary to reduce the hemostatic compression force, medical personnel need to manually pump out excess gas or liquid, which is very inconvenient to operate. In addition, the corresponding pneumatic or hydraulic drive device is installed outside the existing compression hemostatic device, which is not on...

Problems solved by technology

Such compression hemostatic devices usually require an external gas or liquid source (such as an injection syringe used for a balloon-type compression hemostatic device) to operate, and are connected by medical personnel through a connecting tube. The operation is quite complicated and requires operators to have quite high professionalism experience

Especially when it is necessary to reduce the hemostatic pressure, the medical staff also need to manually reduce the excess gas or liquid, which is very inconvenient to operate

In addition, the corresponding pneumatic or hydraulic drive device is installed outside the existing compression hemostatic device, which is not only large in size and complex in structure, but also prone to accidental collisions, and it is not conducive to timely observation of patients' conditions and timely adjustment of treatment methods
