AI Technical Summary

Technical Problem

Existing hemostatic devices require a dedicated syringe for adjusting the expansion amount of the pressing member, imposing a heavy workload on surgeons and making it difficult to apply an appropriate compression force to the puncture site over time.

Method used

A hemostatic device with a support member, pressing member, fixing member, and clamping members that allow for the adjustment of compression force by changing the distance between clamping members, eliminating the need for specialized instruments like syringes.

Benefits of technology

Enables simple operation to adjust the compression force applied to a puncture site, allowing for reversible increase or decrease of compressive force by altering the distance between clamping members, thereby facilitating appropriate hemostasis without the need for additional tools.

Abstract

To provide a hemostatic device capable of adjusting compression force to be applied to a puncture site formed on a patient with simple operation without using a dedicated instrument such as a syringe.SOLUTION: A hemostatic device 10 includes a support member 100 configured to cover a puncture site p formed on a patient, a balloon 210 connected to the support member and configured to compress the puncture site, a fixing member 300 extending from the support member and configured to fix the support member to the puncture part p, and a pair of clamping members 400 facing each other on both sides of the balloon. The pair of clamping members includes a first clamping member 410 and a second clamping member 420 facing the first holding member, with the balloon interposed therebetween. The first clamping member and the second clamping member are configured to be movable close to and away from each other such that a breadth of the balloon can be controlled by changing a distance between the first clamping member and the second clamping member.SELECTED DRAWING: Figure 1
