AI Technical Summary

Technical Problem

In existing technologies, the pressure bandaging device after puncture cannot adjust the pressure as needed, and changing the cotton swab requires removing the bandage, which makes it inconvenient to use.

Method used

An adjustable pressure bandaging device was designed, comprising a tension patch, a binding component, a traction and pulling component, and a medicated cap component. Through the bandaging structure composed of the tension patch and the binding component, multiple movable patches are used to apply pressure to the puncture site, and the medicated cotton can be replaced without removing the bandage.

Benefits of technology

It allows for adjustment of the pressure as needed and replacement of the cotton swabs without removing the bandage, improving the convenience and comfort of use.

Abstract

The application discloses a post-puncture adjustable pressure bandaging device, which comprises a tension patch, a binding part, two converging pulling parts and a medicine cover part. The tension patch is used for being attached to the periphery of a puncture and is capable of exposing the puncture. The binding part is arranged on the tension patch and is used for being bound on a limb together with the tension patch. The two converging pulling parts are symmetrically distributed on the two sides of the tension patch and are connected with the tension patch. The two converging pulling parts are capable of providing two opposite pulling directions to the tension patch, so that the tension patch is uniformly converged to the central position to compress the puncture. The medicine cover part is movably connected with the binding part and is used for covering the puncture in the central region of the binding part. The inside of the tension patch is hollowed out and a plurality of movable patches are arranged for being adhered to the outside of the puncture. After the bandaging structure composed of the tension patch and the binding part is bandaged, the plurality of patches together with the adhered skin can be converged to the puncture by control.
