Disposable Isolation Gown with Tearable Back Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable contact isolation gowns often fail to provide full body coverage, leading to exposure risks for healthcare workers and visitors, and are difficult to put on and remove efficiently, which can compromise infection control in healthcare settings.
Innovation Solution
A disposable contact isolation gown design featuring a front and back panel with arm panels, incorporating lines of weakness for easy removal and adjustable tie members or elastic gatherings for secure fit, fabricated from nonwoven materials like polypropylene or SMS materials, allowing for easy donning and doffing while ensuring complete coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a full coverage gown design is used to ensure complete body protection, then protection effectiveness is improved, but the complexity of donning and doffing increases
Solution Approach 1:
The gown is divided into a front panel and a back panel that are detachably connected. The back panel includes a line of weakness that allows it to be easily torn into separate portions for simple removal. This segmentation enables the gown to provide full body coverage while allowing rapid donning by putting arms through sleeves and simple doffing by tearing the back panel along the line of weakness.
2Reliability
If a secure fit is achieved through adjustable tie members and elastic gatherings, then protection effectiveness is improved, but device complexity increases
Solution Approach 1:
The gown incorporates elastic gatherings at the waist and tie members that allow dynamic adjustment to different body sizes and shapes. The elastic portions provide automatic tension adjustment, while the tie members enable customization of fit. This dynamic adaptability ensures secure fit for various users without requiring multiple gown sizes or complex fastening systems.
3Ease of operation
If easy removal is implemented through lines of weakness, then ease of operation is improved, but gown strength may be compromised
Solution Approach 1:
The back panel includes a line of weakness with specific localized reduced strength properties, while the rest of the gown maintains full protective strength. The line of weakness is strategically positioned and designed with controlled tear propagation characteristics, allowing the gown to remain strong during use but enable rapid removal by tearing along this predetermined weak path without compromising overall protection during the wearing period.
