Inflatable Hemostasis Compression for Foot Artery Punctures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for achieving hemostasis at vascular access puncture sites in the lower leg and foot, particularly in arteries like the anterior tibial, dorsalis pedis, and peroneal arteries, are inefficient and require significant manual effort, leading to potential blood loss and prolonged recovery times.
Innovation Solution
A hemostasis device comprising a body with adjustable coupling tabs, flexible straps, and an inflatable compression member that applies controlled pressure to the puncture site, allowing for quick and secure hemostasis through adjustable securement mechanisms and mechanical compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual compression methods are used to achieve hemostasis at vascular access puncture sites, then hemostasis can be achieved, but significant manual effort is required and blood loss increases
Solution Approach 1:
The compression device is designed to maintain hemostasis automatically after initial application. The ratchet mechanism allows one-way tightening while preventing loosening, and the elastic band automatically maintains compression force without requiring continuous manual adjustment or monitoring by healthcare providers.
Solution Approach 2:
The invention replaces manual mechanical compression with a self-regulating mechanical system. The spring-loaded ratchet mechanism automatically maintains compression force through mechanical means, eliminating the need for continuous manual pressure application while ensuring reliable hemostasis.
2Reliability
If manual compression methods are used to achieve hemostasis, then hemostasis can be achieved, but recovery time is prolonged
Solution Approach 1:
The device allows for rapid initial application and securement of compression. The ratchet mechanism enables quick tightening to the required compression level, and the elastic band is pre-configured to maintain appropriate force, eliminating the need for prolonged manual compression adjustments during the critical hemostasis establishment phase.
3Adaptability or versatility
If adjustable securement mechanisms are implemented in the hemostasis device, then adaptability to different patients is improved, but device complexity increases
Solution Approach 1:
The device is divided into functional modules: an adjustable elastic band for circumferential measurement and customization, a ratchet mechanism for compression control, and a compression element for hemostasis. This segmentation allows each component to perform its specific function independently while contributing to overall adaptability.
Solution Approach 2:
The elastic band incorporates adjustable length and tension capabilities, allowing the device to adapt to different patient anatomies and compression requirements. The dynamic adjustment mechanism enables customization without requiring multiple different device sizes or complex assembly procedures.

AI summary
A hemostasis device configured to apply a compressive force to a puncture site of a patient's vessel, such as an artery of the foot, is disclosed. The hemostasis device may include a compression member having a plurality of tabs and an inflatable bladder. A plurality of bands may be used to position and maintain the compression member over the puncture site until hemostasis is achieved are releasably coupled to the plurality of tabs. A first band can wrap around the ankle, a second band can wrap around the foot, and a third band can extend between two toes or around a toe. The hemostasis device may also comprise an inflation port in fluid communication with the inflatable bladder.
