Solution Overview
Problem
Current vascular access procedures face challenges in achieving effective and efficient hemostasis, as manual compression is painful for patients, inefficient for healthcare providers, and existing vascular closure devices are costly and prone to complications.
Innovation Solution
A vascular hemostasis system comprising a first and second compression member with a compression mechanism and a control system that includes a detecting system and controller to automatically adjust compression based on detected conditions, such as pulse, to facilitate hemostasis without requiring continuous healthcare worker presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual compression is used by healthcare practitioners, then hemostasis can be achieved, but the process is painful for patients and occupies healthcare provider time inefficiently
Solution Approach 1:
The system enables automated hemostasis through a robotic arm that applies compression independently, eliminating the need for continuous healthcare provider presence and reducing patient discomfort associated with manual finger pressure
2Reliability
If manual compression is used by healthcare practitioners, then hemostasis can be achieved, but the healthcare provider must spend more than thirty minutes with the patient
Solution Approach 1:
The automated robotic system performs hemostasis independently without requiring continuous healthcare provider involvement, significantly reducing the time healthcare providers must spend on this routine procedure
Solution Approach 2:
The system replaces manual mechanical compression by healthcare providers with an automated robotic mechanical system, enabling unattended operation and freeing up provider time
3Ease of operation
If vascular closure devices are used, then hemostasis can be achieved without manual compression, but they are expensive and prone to complications
Solution Approach 1:
The system replaces expensive mechanical vascular closure devices with an automated robotic compression system that uses software-controlled mechanical pressure, achieving similar hemostasis results without the cost and complication risks of implantable devices
4Productivity
If automated compression system is implemented, then healthcare worker occupation time is reduced, but system complexity increases
Solution Approach 1:
The system uses a pulse detector as an intermediary sensor to monitor blood flow and provide feedback to the control system, enabling automated adjustment of compression levels without requiring complex direct monitoring of hemostasis completion
Applied Scientific Principles

AI summary
A vascular hemostasis system includes a first compression member and a second compression member separated from the first compression member to create a body part receiving space that is adapted to receive a body part having a vascular opening in need of hemostasis. A compression mechanism connects the first compression member to the second compression member, and the compression mechanism is configured to selectively move the first compression member towards or away from the second compression member to adjust the size of the space and thereby provide varying amounts of compression to the body part. An optional control system includes a detecting system, such as a pulse sensor, and a controller. The controller may be adapted to control the compression mechanism in response to the detecting system. In one version, the compression mechanism includes a locking mechanism that can selectively prevent the first compression member from moving away from the second compression member. The vascular hemostasis system may be used in process to provide hemostasis.
