Wound Dressing Assembly With Inward Clot Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of separating a molded blood clot from the walls of a mold cavity without damaging its integrity, as described in existing wound treatment methods, is addressed by pushing the clot inwardly within the cavity using an auxiliary device with a circumferential member to engage and displace it from the walls.
Innovation Solution
An auxiliary device with a circumferential member is used to push the molded blood clot inwardly within the mold cavity, allowing it to separate from the walls without significant damage, facilitating easy extraction and application onto a wound.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the molded blood clot is extracted directly from the mold cavity, then the extraction process is simple, but the clot sticks to the walls and its integrity is damaged
Solution Approach 1:
Instead of pulling the clot outward for extraction, the invention pushes the clot inward toward the interior of the mold cavity. This reverse action causes the clot to separate from the walls naturally, allowing easy extraction while preserving integrity. The circumferential member pushes the clot inward, making separation occur in the opposite direction of traditional extraction.
Solution Approach 2:
A circumferential member is introduced as an intermediary tool between the operator and the blood clot. This member engages the clot and pushes it inward, mediating the separation process from the mold walls without direct manual manipulation that could damage the clot's integrity.
2Stability of the object's composition
If the clot is pushed inward to separate from walls, then the clot integrity is preserved, but an auxiliary device is required increasing complexity
Solution Approach 1:
The auxiliary device is segmented into a body and a circumferential member that can be held manually. This segmentation allows the device to be simple enough for manual operation while still providing the necessary function of pushing the clot inward without requiring complex mechanical systems.
3Productivity
If the clot is extracted without inward pushing, then the process is faster, but the clot adheres to walls causing damage
Solution Approach 1:
The inward pushing action is performed as a preliminary step before extraction. By pushing the clot inward first to separate it from the walls, the subsequent extraction becomes fast and simple without compromising integrity. This preliminary action prevents the adhesion problem that would otherwise slow down or complicate the extraction process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method ensures the integrity of the blood clot is preserved during extraction, enabling its safe application onto a wound, either alone or combined with dressing materials.
Implementation Method 1
pushing the clot in a direction towards the interior of the mold cavity... By pushing this device against the molded blood clot, it displaces towards the interior of the mold cavity
Implementation Method 2
the blood is clotted in said mold and after clotting, the clotted blood mass is transferred onto a wound

AI summary
The present disclosure provides a wound dressing assembly comprising (i) a blood-clotting mold device with a mold cavity for forming a molded blood clot for use in dressing a wound. Prior to extraction, the molded blood clot is pushed towards the mold cavity's interior, which causes the molded blood clot to disassociate from the cavity walls and thereafter it can be removed with none or only minimal damage to its integrity.
