Rotating Feeding Container Seal Splitting for Liquid Medical Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for treating liquid medical waste are inconvenient and pose a risk of secondary infection due to the need to open a top cover for adding coagulants, which can block the outflow and cause material to fall into the waste, complicating the treatment process.
Innovation Solution
A feeding system with a feeding container and receiving container, featuring guide slots and lugs that allow the feeding container to rotate and split a seal to allow coagulant flow without completely cutting it, preventing blockages and seal loss, and ensuring safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the top cover is opened to feed coagulant into the liquid waste collection bag, then the coagulant can be added to treat the waste, but this causes inconvenience to the doctor's operations and might cause secondary infection due to improper operations
Solution Approach 1:
The feeding container is nested within the receiving container, with the feeding container's outlet positioned inside the receiving container's liquid waste collection bag. This allows coagulant to be fed directly into the waste without opening the top cover, eliminating exposure to bacteria while maintaining ease of operation through a simple rotational feeding mechanism
2Reliability
If a feeding container with an openable feeding outlet is used, then the operation is relatively safer, but the structure or material intended to seal the feeding outlet might block the outflow of coagulant when opened
Solution Approach 1:
The sealing structure is extracted from the feeding outlet and repositioned at the feeding container's outlet opening. When the feeding container rotates to feed coagulant, the seal automatically opens to allow outflow and then closes afterward. This separation ensures complete coagulant flow without blockage while maintaining safety through automatic sealing
3Reliability
If a feeding container with an openable feeding outlet is used, then the operation is relatively safer, but the structure or material intended to seal the feeding outlet may fall into the liquid medical waste when opened
Solution Approach 1:
The sealing structure is nested within the feeding container's outlet opening rather than being part of the openable feeding outlet. When the feeding container rotates to feed coagulant, the seal remains positioned at the outlet and automatically opens and closes without detaching. This prevents the seal from falling into the liquid medical waste while maintaining safety through automatic sealing action

AI summary
The present disclosure discloses a feeding system for treating liquid medical waste. The feeding system comprises a receiving container for storing liquid medical waste and a feeding container for accommodating a coagulant. The feeding container comprises an outlet and a seal for closing the outlet, and the receiving container comprises a feeding connector with a feeding channel. The feeding container and the receiving container are provided with a guide mechanism comprising guide lugs and guide slots, and the feeding connector is provided with a plurality of splitting portions arranged along the circumferential direction of the feeding channel and spaced apart from each other by a certain distance. The guide mechanism allows the operation of rotating the feeding container by a predetermined angle relative to the receiving container, and this operation causes the splitting portions to cut the seal along the circumference of the feeding channel to destruct the seal, thereby causing the coagulant accommodated in the feeding container flows into the receiving container through the outlet. The present disclosure provides a safe and convenient operation manner for adding a coagulant into a storage container of liquid medical waste.
