Expansion pressurization band-aid/plaster and preparation method thereof

Abstract

The invention discloses an expansion pressurization band-aid/plaster, which belongs to the technical field of medicine and health. According to the invention, a continuous compression hemostasis effect can be easily obtained after one-time pressurization, so operation is simple, use is convenient, hemostasis compression force is fully improved, and an effective hemostasis effect can be achieved on various wound surfaces and bleeding conditions. The invention further provides a preparation method of the expansion pressurization band-aid/plaster. According to the invention, graphene fibers used in the method have excellent broad-spectrum antibacterial and antiviral capacity, and a preparation process is simple; while the prepared band-aid/plaster can provide pressure continuously, better bacteriostasis and virus resistance can be achieved, and the healing efficiency of a wound is improved; and graphene nanoplatelets tightly cover the surfaces of the fibers, so the elastic strength of the fibers is improved, the graphene nanoplatelets are not easy to fall off, the risk of graphene falling off under the conditions of water, blood and other special solutions is greatly reduced, the band-aid/plaster is not easy to damage and prolonged in service life. The band-aid/plaster of the invention has obvious effect and is suitable for wide popularization.

Description

Technical field [0001] The present invention relates to the field of medical and health technique, and particularly relates to a Band-Aid / applicator and a method for preparing expandable pressure. Background technique [0002] When the skin is cut, or injection, blood, etc. after the operation, the skin puncture site of the bleeding wound will typically occur continuously, cotton or attached to the pressing need for a disposable adhesive bandage to stop bleeding oppressive. However, the conventional disposable bandage only functions as an external surface of the skin surrounding the wound is formed and attached to functionality, pressure is weak, or patient in need of treatment a bandage art is continuously pressed in the vertical direction of the outer surface of the bleeding site in order to achieve the desired hemostatic effect, causing great inconvenience to the patient and treatment personnel. Since the hemostasis time is usually 15-30 minutes, if the case of the large amo...

Problems solved by technology

[0004] In view of the above-mentioned defects, the technical problem to be solved by the present invention is to provide an inflatable pressurized band-aid / applicator and a preparation method to solve the problems existing in the current technology that it is difficult to maintain the pressed state for a long time by pressing the wound for hemostasis, repeated contact is unhygienic, and it is easy to Delayed healing speed; due to unstable pressing pressure, blood vessel overpressure and congestion at the wound are prone to occur, or the effect of hemostasis is not good if the pressure is too low; it needs the assistance of others and is not easy to operate alone
