Abstract

The invention provides a special hemostasis pressing mechanism for internal arteriovenous fistula, belongs to the technical field of medical instruments, and aims to solve the problems that according to a traditional hemostasis method, repeated utilization cannot be achieved, a lot of tourniquets are wasted, and the pressing force cannot be effectively controlled. The connecting assemblies are fixedly mounted at the left and right ends of the supporting device; the left end and the right end of the pressing hemostasis assembly are connected with the supporting device. The pressure auxiliary control device is in sliding connection with the supporting device; the replaceable adhesive sheet and the replaceable hemostatic cotton are arranged in the device and can be repeatedly used, and waste of the tourniquet is effectively reduced; a pressure auxiliary control device is arranged in the device, a rubber pressing block can be directly inflated and expanded through a sliding column, then the effect of controlling the pressing pressure is achieved, and the device is simple, practical, low in manufacturing cost and suitable for large-scale production and use.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more particularly relates to a special hemostasis pressing mechanism for an arteriovenous fistula. Background technique [0002] Arteriovenous fistula is one of the surgical operations, mainly used for hemodialysis treatment; arteriovenous fistula is a small operation of vascular anastomosis. The arteries and adjacent veins of the forearm near the wrist are sutured, so that the anastomotic arteries and adjacent veins are sutured. Arterial blood flows in the veins, forming an arteriovenous fistula. At the end of each dialysis treatment, it is crucial for the patient to choose an appropriate method for puncturing the injured fistula blood vessels to compress and stop the bleeding. [0003] Based on the above, the traditional method of hemostasis is to stop the bleeding by manually pressing and pasting a tourniquet. The tourniquet must be discarded after it is used up, and cannot be reus...
