Drawstring Indicator System for Medical Drape Bag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical personnel are exposed to biohazard materials during the removal and disposal of contaminated equipment and absorbent drapes in medical and surgical procedures due to the lack of a clear indication of contents within the combined drape and carrying bag unit without opening it.
Innovation Solution
A drawstring-based indicator system integrated into the combined drape and carrying bag unit, where the indicator is hidden in the mat configuration and becomes visible when the unit is converted into a carrying bag configuration, providing information on the contents through preprinted information, barcodes, or inscription space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the combined drape and carrying bag unit is designed to be closed and sealed, then medical personnel exposure to biohazard materials is reduced, but the ability to identify contents without opening the bag is lost
Solution Approach 1:
An indicator system serves as an intermediary element that communicates bag contents information without requiring the bag to be opened. The indicator is attached to the drawstring and becomes visible when pulled, providing information about contents while maintaining the sealed, protective function of the bag.
Solution Approach 2:
The indicator system provides visual feedback about the bag contents to medical personnel. When the drawstring is pulled to convert the drape into a carrying bag, the indicator becomes visible and communicates information about what is inside the bag, enabling informed handling decisions without compromising the sealed protective function.
2Loss of information
If the indicator is attached to the drawstring and positioned to be visible when pulled, then contents identification is enabled, but the indicator may be visible during the procedure in mat configuration
Solution Approach 1:
The indicator is pre-positioned on the drawstring at a specific distance from the drawstring casing opening. This preliminary positioning ensures that when the drawstring is pulled during conversion to bag configuration, the indicator will be drawn out and become visible at the appropriate time, providing contents identification without being visible during the procedure setup phase.
3Loss of information
If the indicator is made large enough to be clearly visible, then contents identification is improved, but the indicator occupies more space within the drawstring casing
Solution Approach 1:
The indicator system is segmented into functional zones: the indicator itself carries the contents information, while the drawstring and drawstring casing provide the deployment mechanism. This segmentation allows the indicator to be optimally sized for visibility without requiring excessive space in the casing, as the drawstring system efficiently manages the indicator's position and deployment.

AI summary
The present specification discloses a combined drape and carrying bag unit used in medical and surgical settings with an indicator attached to a drawstring of the unit. Conversion of the unit from a drape or mat configuration involves pulling on exposed drawstring sections and results in deployment of the identifying indicator. The indicator includes preprinted information, a barcode for scanning, and/or space for the inscription of information by medical personnel. The inclusion of an integrated indicator with the combined drape and carrying bag unit informs medical personnel of the contents of the unit when in the bag configuration and obviates the need for opening the bag and discovering its contents, thereby reducing exposure of medical personnel to biohazard waste.
