Hemostasis bandage

Abstract

The invention discloses a hemostasis bandage, comprising a fixing plate of which the central part is provided with a through-hole, a screw column which passes through the through-hole of the fixing plate, a silica gel press block which is fixedly connected on the lower end of the screw column, a floating nut which is screwed on the screw column, a bandage body which is fixed on the fixing plate, a fixing belt which is connected to the two end sides, an outer rotary sleeve of which the bottom surface is opened and the top surface is provided with the through-hole, wherein the screw column passes through the through-hole, and a spring which is located between the top surface of the outer rotary sleeve and the floating nut. An annular pump formed by the outer circumference of the bottom surface of the outer rotary sleeve extending outside is arranged in an annular clamp groove which is formed by fixedly connecting the fixing plate with the bandage body. The inner lateral wall of the outer rotary sleeve is provided with a plurality of grooves which are matched with the convex edges in the outer lateral wall of the floating nut. The invention buffers the pressure through arranging the spring based on adjusting the compression strength and gives some mobility to person, so it has good hemostasis effect.

Description

technical field [0001] The invention relates to a medical hemostatic bandage. Background technique [0002] At present, after pulling out the puncture needle or indwelling needle in the puncture operation, finger pressure is generally used to stop the bleeding. However, due to manual pressure to stop the bleeding, the force of the implementation is not easy to maintain stability, often resulting in failure to stop the bleeding, and it is necessary to press again to stop the bleeding. Labor intensity, on the other hand, also causes pain to patients. Therefore, the applicant applied for a patent "a hemostatic bandage" with the patent application number 201020147967.X in 2009, and obtained the authorization. [0003] The hemostatic bandage in the above-mentioned original patent is composed of a fixing plate, a fixing belt and an adjustable compressing device, which can adjust the compressing intensity and play a hemostatic effect. However, it can only rely on the experience o...

AI Technical Summary

Problems solved by technology

However, it can only rely on the experience of medical staff to adjust the compression intensity. There is no buffer, and the patient has no mobility. When the adjustment amount is relatively large, it is easy to bring pain to the patient.

At the same time, there is no pressure display on the original hemostatic bandage, and it is impossible to check whether the puncture point is bleeding
