Flexible Extraction Bag with Pneumatic Chamber for Trauma-Free Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools used in childbirth, such as forceps and vacuum devices, pose risks of injury to newborns and mothers due to difficulties in inserting and extracting the fetus safely, particularly in uterine cavity insertion and movement during delivery.
Innovation Solution
A device comprising a flexible, hypoallergenic bag with an external air chamber connected to an air injection system and a traction handle, allowing controlled air pressure to facilitate the extraction of the fetus without traumatism, using a cannula and presostatic measuring gauge to manage pressure and prevent injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If forceps or vacuum devices are used for childbirth assistance, then extraction capability is improved, but risk of injury to newborns and mothers increases
Solution Approach 1:
The device uses an air chamber connected to an air injection system that inflates to envelop the fetus, providing gentle pneumatic support for extraction without mechanical trauma. The controlled air pressure replaces the need for forceful mechanical instruments like forceps or vacuum devices.
Solution Approach 2:
The device employs a flexible bag made of elastomeric material that can adapt its shape to envelop the fetus gently. This flexible shell conforms to the fetal contours, distributing pressure evenly and avoiding concentrated stress points that could cause injury.
2Force
If rigid mechanical tools are used for extraction, then extraction force is improved, but trauma to the mother or child increases
Solution Approach 1:
The device generates extraction force through controlled inflation of the air chamber rather than mechanical leverage. The expanding air pressure gently pushes the fetus outward, providing sufficient extraction force without the concentrated pressure points and tissue damage associated with rigid mechanical tools.
Solution Approach 2:
The invention replaces the mechanical system of forceps or vacuum extractors with a pneumatic system. Instead of using levers, clamps, or suction, the device uses controlled air pressure to achieve extraction, eliminating the trauma caused by mechanical contact points.
3Ease of operation
If air pressure is increased to facilitate extraction, then extraction ease is improved, but risk of pressure-related injury increases
Solution Approach 1:
The device incorporates a presostatic gauge that provides real-time feedback on the air pressure within the chamber. This allows the operator to monitor and adjust the pressure continuously, ensuring it remains within safe limits while still achieving effective extraction. The feedback mechanism prevents pressure from reaching dangerous levels.
Solution Approach 2:
The air pressure is not static but dynamically adjusted during the extraction process. The operator can inflate the chamber gradually, monitor the presostatic gauge, and release pressure as needed, adapting the pressure level to the specific needs of each extraction stage and avoiding excessive pressure that could cause injury.
