Twin-Pouch Parturition Drape for Separate Fluid Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical procedures face challenges in efficiently collecting and measuring fluids such as amniotic fluid and placenta fluid during childbirth, as current methods do not allow for accurate separation and measurement, leading to difficulties in assessing blood loss and requiring further medical attention.
Innovation Solution
A parturition drape with a twin pouch assembly is designed, featuring a flap to guide fluids into separate pouches for amniotic and placenta fluids, equipped with a graduated fluid measurement device for precise volume assessment, allowing healthcare providers to distinguish and measure each fluid type accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single collection method is used for all fluids during childbirth, then the device complexity is reduced, but the measurement precision of different fluid types deteriorates
Solution Approach 1:
The collection system is divided into multiple separate pouches (first pouch for amniotic fluid, second pouch for placental fluid) instead of using a single collection container. This segmentation allows each pouch to collect and measure specific fluid types separately, thereby improving measurement precision while maintaining relatively simple device structure through modular design.
2Measurement precision
If fluids are collected separately in multiple pouches, then the measurement precision of different fluid types is improved, but the device complexity increases
Solution Approach 1:
Multiple pouches with different functions (collection pouches, measurement pouches) are merged into a single integrated twin pouch assembly that attaches to the drape. This combining approach allows separate collection and measurement of different fluids while presenting a unified, manageable device structure, thus improving fluid type differentiation without excessively increasing operational complexity.
Solution Approach 2:
The twin pouch assembly serves multiple functions simultaneously: it collects different fluid types, measures their volumes, and provides visual differentiation. This multi-functionality is achieved through a single integrated assembly that combines collection and measurement capabilities, thereby improving measurement precision while keeping the device structure relatively compact and manageable.
3Productivity
If fluid collection and measurement are performed simultaneously, then the productivity of fluid assessment is improved, but the measurement precision may deteriorate due to lack of separation
Solution Approach 1:
The system performs preliminary separation of fluids into different pouches based on their source (amniotic fluid vs. placental fluid) before measurement occurs. This preliminary action ensures that each fluid type is already separated and identified before the measurement process begins, thereby maintaining high measurement precision for blood loss assessment while enabling simultaneous collection and measurement through the integrated assembly.

AI summary
A parturition drape (100) includes a drape (101) and a twin pouch assembly (102). The twin pouch assembly defines a first pouch (1101) and a second pouch (1301) attached to a major face of the drape. A flap (103) is attached to the major face of the drape. The flap (103) is selectively insertable into an open end of either the first pouch or the second pouch.
