Compression Device Liquid Guide Member Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compression devices struggle with easy detachment from the living body surface after hemostasis, potentially causing skin damage due to high adhesive forces.
Innovation Solution
A compression device with an adhesive sheet, an expandable expansion member, and a liquid guide member that allows release liquid to permeate, facilitating easy detachment by weakening the adhesive force through the capillary action of the liquid guide member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a compression device uses a strong adhesive sheet to ensure secure attachment during hemostasis, then the attachment reliability is improved, but the ease of detachment deteriorates and skin damage risk increases
Solution Approach 1:
The release liquid is applied in advance to the liquid guide member before the compression device is attached to the patient's body. This preliminary action allows the release liquid to be positioned exactly where needed, enabling easy detachment later without requiring additional application steps or causing skin damage.
Solution Approach 2:
The liquid guide member acts as an intermediary component between the adhesive sheet and the patient's skin. It channels the release liquid to the interface between the adhesive and skin, mediating the detachment process by weakening the adhesive bond in a controlled manner, thus enabling easy removal without direct skin damage.
2Stability of the object's composition
If the adhesive sheet maintains strong adhesion to ensure stable compression, then the compression stability is improved, but the skin irritation risk worsens during detachment
Solution Approach 1:
The release liquid is applied in advance to the liquid guide member before compression begins. This ensures that when detachment is needed, the release liquid is already in position to immediately weaken the adhesive bond, reducing skin irritation risk while maintaining compression stability during the compression phase.
Solution Approach 2:
The liquid guide member serves as an intermediary that delivers the release liquid precisely to the adhesive-skin interface. This controlled delivery mechanism allows the adhesive to maintain strong bonding during compression while providing a safe detachment path that minimizes skin irritation when removal is required.
