Drainage Tube Plaster Fixation with Support Band
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drainage tube fixing devices fail to securely fix the tube against lifting and longitudinal movement, potentially causing skin pressure and discomfort, and do not effectively prevent bacterial growth due to tube bending.
Innovation Solution
A plaster system with support pads and a detachable support band that includes holders and a protective housing to securely fix the drainage tube, preventing movement and skin contact, while accommodating the 3-way valve and connectors to maintain stability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional drainage tube fixing devices are used, then the drainage tube can be fixed to the body, but the tube cannot be firmly fixed against lifting and longitudinal movement
Solution Approach 1:
The fixing device is divided into multiple functional segments: adhesive pads for base attachment, a support band for circumferential fixation, and holders for specific tube positioning. This segmentation allows each component to address specific movement directions, achieving comprehensive stabilization against both lifting and longitudinal movement.
Solution Approach 2:
The support band wraps around the body in a circumferential direction, adding a third dimension of constraint to the traditional planar fixation. This dimensional approach prevents lifting movement by distributing fixation force around the body, while the holders constrain longitudinal movement, together providing multi-directional stability.
2Reliability
If conventional drainage tube fixing devices are used, then the tube can be secured, but skin pressure and pain occur due to lack of protective structure
Solution Approach 1:
The support band acts as an intermediary structure between the drainage tube components (3-way valve, connectors) and the patient's skin. It provides a protective barrier that distributes pressure evenly and prevents direct contact between hard tube components and the skin, thereby eliminating pressure points and pain while maintaining secure fixation.
3Ease of operation
If the drainage tube is allowed to move, then fixation flexibility is maintained, but bacterial growth occurs due to tube bending and liquid stagnation
Solution Approach 1:
Instead of allowing tube movement and accepting bending as inevitable, the invention inverts the approach by providing rigid constraints through holders and support band that actively prevent bending. This ensures liquid flows smoothly through the tube without stagnation, eliminating the condition for bacterial growth while maintaining appropriate fixation flexibility through the adjustable support band.

AI summary
A plaster for fixing a drainage tube is provided, which fixes the drainage tube that is inserted into a patient's body and discharges liquid inside the patient's body to the outside of the patient's body. The plaster includes a plurality of support pads attached to the patient's body to be spaced apart from each other, each of the plurality of support pads having a certain thickness; a support band fixed to respective upper surfaces of the support pads to cover the skin; and a plurality of holders detachably coupled to an upper surface of the support band to hold and fix the drainage tube. The plaster for fixing a drainage tube maintains a stable fixation state by blocking longitudinal movement of the drainage tube as well as lifting of the drainage tube, and protects the skin from a 3-way valve to prevent pain even when the skin is pressed.
