AI Technical Summary

Technical Problem

Existing medical puncture point compression hemostatic dressings cannot accurately determine the compression time and lack an effective anti-displacement structure, which makes the compression position easy to shift and affects the hemostatic effect.

Method used

A multi-layer composite medical dressing is designed, comprising a pre-colored flexible substrate layer, a temperature-sensitive indicator unit, a pressure function layer, and an elastic positioning layer. The color change of the temperature-sensitive indicator unit intuitively indicates the pressure time, and the elastic positioning layer adapts to the movement of the skin and blood vessels to prevent the dressing from shifting.

Benefits of technology

It provides a visual indication of compression time, ensuring the accuracy and effectiveness of compression location, improving hemostasis and ease of operation, and keeping the wound clean.

Abstract

The invention discloses a medical puncture point protection application and a preparation method and application thereof, and relates to the field of medical dressing pastes.The protection application is configured to be a multi-layer composite basic protection application which is used for compression hemostasis of a puncture point and has a temperature sensing color changing indication function. The multi-layer composite basic protective application comprises a second protective layer, a compression function layer, a pre-coloring flexible base material layer and a peelable protective layer which are sequentially arranged in a stacked mode. According to the medical puncture point protection application, the preparation method and the application thereof, visual objective indication of compression time is achieved through visual comparison of the temperature-sensitive color-changing material and the pre-coloring background layer, and meanwhile the application is prevented from shifting through the elastic positioning layer.
