Dorsal Forearm Plate with Anatomical Contours and Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radial artery compression systems lack precise and adjustable pressure application, stability during procedures, and comfort for patients, leading to potential bleeding complications and venous stasis.
Innovation Solution
A dorsal forearm plate with a flexible, transparent compression unit that fits the anatomy of the forearm, providing controlled pressure and visibility over the puncture site, and attachment bands for secure fixation, allowing for adjustable pressure and reduced wrist movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid compression device is used to apply pressure to the radial artery, then haemostasis effectiveness is improved, but patient comfort and adaptability to forearm anatomy deteriorate
Solution Approach 1:
The compression device uses a flexible plate instead of a rigid structure. The plate can conform to the curved surface of the forearm while maintaining compression force application capability, thus resolving the contradiction between maintaining haemostasis effectiveness and adapting to anatomical variations.
Solution Approach 2:
The device allows adjustment of compression pressure parameters to match different patients and anatomical conditions. By making the compression force adjustable, the device can adapt to various forearm sizes and shapes while maintaining effective haemostasis.
2Difficulty of detecting and measuring
If a transparent compression element is used to monitor the puncture site, then visibility and detection capability are improved, but structural strength and compression effectiveness deteriorate
Solution Approach 1:
The compression element is made from a transparent material that combines optical transparency with mechanical strength. This composite material property allows simultaneous achievement of puncture site visibility and effective compression force application.
3Stability of the object's composition
If multiple straps are used to secure the compression device, then fixation stability is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
Multiple compression functions are merged into a single integrated plate structure. The plate itself provides both compression and stabilization functions, eliminating the need for multiple separate straps and buckles, thus reducing device complexity while maintaining fixation stability.
4Manufacturing precision
If the compression device is designed to be adjustable for pressure control, then haemostasis precision is improved, but ease of operation and manufacturing complexity worsen
Solution Approach 1:
The device incorporates adjustable elements that allow dynamic pressure control. The adjustment mechanism is designed to be simple and intuitive, enabling precise pressure control without significantly increasing manufacturing complexity.

AI summary
Dorsal forearm plate having a three-dimensional concave shape adapted to the shape of the dorsal forearm such that the dorsal forearm may rest on the forearm plate, the dorsal forearm plate has an essentially rectangular extension having opposing long sides and opposing short sides and has a substantially rigid unitary body adapted to underlie the posterior of the patient's hand, wrist and forearm, the plate is provided with two attachment bands, a distal and a proximal attachment band, adapted to attach the plate at the dorsal forearm of a patient. The shape of the side of the plate adapted to face the forearm during use, is adapted to the anatomy of the forearm in that it comprises two elongated depressions running in the longitudinal direction of the plate such that, during use of the plate, the ulnar bone and radius bone of the patient rest in the respective depression and that an elongated ridge, formed between the depressions, is adapted to extend into the softer tissue between the bones in order to orient and stabilize the forearm when attached to the plate. The invention also relates to a radial artery compression system comprising a dorsal forearm plate and a compression unit.
