Vessel Clamping Pressure Device for Continuous Bleeding Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vascular closure devices fail to effectively manage continuous bleeding at vascular access sites post-procedure, necessitating caregiver presence to apply pressure for extended periods, which delays patient transfer to the recovery area.
Innovation Solution
A vessel clamping pressure device that applies mechanical tension to suture threads using a mechanism with a pressure-applying surface, allowing for continuous pressure application on the vascular vessel closure site, facilitating clotting and reducing bleeding without the need for prolonged caregiver presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual pressure application by caregiver is used to close vascular vessel, then bleeding control is achieved, but surgery room occupation time increases and patient transfer is delayed
Solution Approach 1:
The device applies pressure to the vascular vessel closure site through its own weight and mechanical structure, eliminating the need for continuous caregiver intervention. The self-retaining design allows the device to maintain pressure independently, enabling patient transfer to recovery area while ensuring reliable bleeding control throughout the required compression period.
2Reliability
If prolonged caregiver presence is required for pressure application, then continuous monitoring of closure site is possible, but procedural throughput decreases
Solution Approach 1:
The device autonomously maintains pressure on the closure site through its weighted design and mechanical retention mechanisms, providing continuous monitoring capability without requiring caregiver presence. This self-sustaining approach enables multiple procedures to be performed in parallel, significantly improving procedural throughput while maintaining reliable closure site monitoring.
3Ease of operation
If weighted bags or finger pressure are used for vessel closure, then pressure application is simple, but device complexity increases when automation is introduced
Solution Approach 1:
The device employs a weighted structure with self-retaining mechanical features that automatically maintain pressure on the vascular closure site. The design incorporates simple yet effective mechanisms such as weighted compression surfaces and self-locking features that require minimal operator intervention while providing consistent, reliable pressure application throughout the healing period.

AI summary
Various embodiments include a vessel clamping pressure device that is configured to receive suture threads extending from the closure of a vascular vessel of a patient, and maintaining tension on suture threads between the patient and the vessel clamping pressure device to apply pressure to the patient so as to apply a clamping pressure to the vascular vessel to facilitate clotting. In some embodiments, a pressure applying surface may include a cushioning material configured to cushion application of the pressure applying surface the patient.
