AI Technical Summary

Technical Problem

Existing hemostatic sponges cannot effectively cover irregular wounds, and additional cutting tools are required in emergencies, increasing operation time and complexity, and affecting hemostasis and emergency response efficiency.

Method used

A medical polyvinyl alcohol sponge strip that can expand axially and radially is designed. Combined with a solid syringe, the sponge strip is designed with segments, a push plate, and an arc groove to ensure stable and all-round pressure hemostasis, adapting to different wound shapes and sizes.

Benefits of technology

It achieves comprehensive coverage of irregular wounds, significantly improves hemostasis, simplifies operation procedures, shortens treatment time, reduces patient risk and discomfort, and increases the success rate of emergency treatment.

Abstract

The application discloses a hemostatic device applied to various irregular wounds and belongs to the technical field of medical first-aid equipment, which comprises a solid syringe and a medical polyvinyl alcohol sponge strip; the medical polyvinyl alcohol sponge strip can be axially and radially expanded and is punched into a wound by the device, and the sponge strip is used for omnibearing compression hemostasis; meanwhile, the segmented design of the sponge strip allows the selection of a proper number of segments according to the actual length of the wound, so that the wound can be completely covered; after the sponge strip enters the wound, the sponge strip rapidly absorbs blood and expands, generates uniform pressure, effectively seals blood vessels and achieves the purpose of hemostasis; the radial and lateral expansion of the hemostatic sponge strip is realized, the irregular wound is fully covered, the hemostasis effect is remarkably improved, the segmented design makes the hemostatic device capable of flexibly adapting to wounds of different sizes and shapes, the use of additional cutting tools is reduced, the operation process is simplified, the efficient hemostasis mechanism shortens the treatment time, reduces the risk and discomfort of patients and improves the success rate of first aid.
