Manifold Sleeve System for Bone Tissue Pressure Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reduced pressure systems for tissue treatment face challenges in effectively applying and maintaining reduced pressure, particularly in bone tissue sites, which can lead to inefficiencies in healing and tissue growth due to clogging issues and limited accessibility.
Innovation Solution
A reduced-pressure treatment system comprising a manifold and sleeve configuration that allows for easy insertion, removal, and repositioning of the manifold, with features like apertures for fluid delivery and purging, and a flexible sleeve for subcutaneous use, facilitating the application of reduced pressure to bone tissue sites while minimizing disruption and promoting tissue growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reduced pressure source is applied to tissue through a porous pad or manifold device, then reduced pressure therapy benefits (tissue migration, blood flow, granulation tissue development) are achieved, but clogging issues occur that reduce system reliability
Solution Approach 1:
The system divides the manifold device into multiple segments or channels, each with its own aperture array. This segmentation prevents complete clogging by providing alternative flow paths if one segment becomes blocked, thereby maintaining system reliability while continuing to deliver reduced pressure therapy benefits.
Solution Approach 2:
A filter or protective layer is introduced as an intermediary between the tissue site and the manifold apertures. This intermediary layer prevents debris and exudate from directly clogging the apertures while still allowing reduced pressure to be effectively transmitted to the tissue, resolving the contradiction between maintaining reliable pressure delivery and preventing clogging.
2Ease of operation
If the manifold device is fixed in position, then stable reduced pressure application is maintained, but accessibility for insertion, removal, and repositioning is limited
Solution Approach 1:
The manifold device incorporates dynamic positioning capabilities, allowing it to be easily inserted, removed, and repositioned within the tissue site. The device maintains stability during operation through secure anchoring mechanisms while enabling operational flexibility, thus achieving both ease of operation and position stability.
Solution Approach 2:
The manifold device is designed with a nested structure that allows it to be inserted into or along with the sleeve. This nesting arrangement facilitates easy insertion and removal while maintaining stable positioning once deployed, as the nested components work together to secure the manifold in place while allowing for operational access.
3Ease of operation
If the manifold is repeatedly inserted and removed from the sleeve, then accessibility and repositioning are improved, but tissue disruption and damage may occur
Solution Approach 1:
The system is designed to achieve the desired therapeutic effect within a predetermined treatment period, minimizing the need for repeated insertion and removal of the manifold. The preliminary design of the aperture distribution and pressure delivery ensures effective tissue treatment is achieved during the initial placement, reducing subsequent manipulations that could cause tissue disruption.
Solution Approach 2:
The sleeve and manifold design incorporates cushioning or protective features that minimize tissue disruption during insertion, removal, and repositioning operations. These beforehand protective measures reduce mechanical stress and trauma to the surrounding tissue while maintaining the ability to reposition the device as needed for optimal therapy delivery.
