Manual Vascular Compression Device with Off-Center Shaft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vascular compression devices are costly, difficult to maintain, consume space, and are not ideal for achieving hemostasis due to suboptimal compression methods, often leading to prolonged procedures and risk of repetitive stress injuries for healthcare professionals.
Innovation Solution
A manual vascular compression device with a handle, shaft, and pad that allows for simultaneous compression at the skin and blood vessel levels, enabling rocking motion along the catheter track for improved hemostasis, featuring a convex pad and off-center shaft for enhanced control and stability, and optionally using a disposable unit with a visual guide and alignment grooves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated compression devices are used, then hemostasis efficiency is improved, but device cost and complexity increase
Solution Approach 1:
The device allows manual operation by the user themselves without requiring external automated systems, pneumatic sources, or electrical power. The user directly applies compression force through the handle and shaft to the pad, eliminating the need for complex automated mechanisms while maintaining hemostasis effectiveness
Solution Approach 2:
The invention extracts only the essential compression function from complex automated devices, removing unnecessary automated mechanisms, control systems, and power sources. The core compression capability is retained while eliminating device complexity through manual operation
2Device complexity
If traditional manual pressure application is used, then device simplicity is maintained, but user fatigue and injury risk increase
Solution Approach 1:
The shaft acts as an intermediary mechanical lever between the user's hand on the handle and the compression pad on the patient's body. This lever arm allows the user to apply compression force with reduced direct muscle effort, decreasing fatigue and injury risk while maintaining device simplicity
Solution Approach 2:
The invention adds the dimensional aspect of mechanical leverage through the shaft and handle configuration. Instead of direct finger pressure, the user applies force at a distance from the compression point, utilizing mechanical advantage to reduce the physical effort required and minimize user fatigue
3Reliability
If prolonged compression is applied to achieve hemostasis, then hemostasis effectiveness is improved, but user fatigue and procedural time increase
Solution Approach 1:
The device enables proper positioning and alignment of the compression pad before applying force. The shaft and handle configuration allows the user to pre-position the pad correctly on the femoral artery, ensuring immediate effective compression upon application, which reduces the time needed to achieve hemostasis while maintaining effectiveness
4Device complexity
If direct finger pressure is used, then device simplicity is maintained, but exposure to patient blood and contamination risk increase
Solution Approach 1:
The shaft and handle serve as intermediary structures that transmit compression force from the user's hand to the compression pad without requiring direct contact between the user's fingers and the patient's body or blood. This maintains device simplicity while eliminating blood exposure and contamination risks

AI summary
A vascular compression apparatus and method for applying pressure onto an area of a patient generally including a blood vessel and a wound site, such as a blood vessel puncture, after a cannulated procedure for the purpose of controlling bleeding and achieving hemostasis. The vascular compression apparatus includes a handle, a shaft and a pad. The shaft extends generally downward from the center of the bottom side of the handle. The pad is connected generally off-center of its top side to the bottom end of the shaft. The bottom side of the pad is convex to allow the vascular compression device to be rocked back and forth. In use, the pad is generally placed proximal to the catheter insertion site and over the blood vessel containing the catheter. The device is rocked proximally to control blood flow while removing the catheter. After the catheter is removed from the puncture site, the device is rocked distally to the puncture site, where pressure is applied until hemostasis is achieved.
