Solution Overview
Problem
Existing medical waste collection systems face challenges in ensuring safe and efficient coupling and decoupling of manifolds, which are crucial for filtering waste material without clogging or compromising system components, particularly in surgical settings.
Innovation Solution
A system is developed with a manifold that includes a first circuit with memory devices and authentication mechanisms, ensuring compatibility with surgical waste collection rovers, and a method for manufacturing and cleaning manifolds to ensure secure and efficient integration with waste collection units, using encryption and hash digests to authenticate and track usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter element is included in the manifold to filter waste material, then clogging or compromise of system components is avoided, but the device complexity increases
Solution Approach 1:
The filter element is nested within the manifold housing, with the collection chamber positioned between the filter element and the outlet. This nested arrangement integrates multiple functions (filtration, collection, and discharge) into a single compact unit, avoiding the need for separate external filter housings while protecting system components from clogging.
2Reliability
If authentication mechanisms with memory devices and encryption are implemented in the manifold, then unauthorized use is prevented and system integrity is maintained, but the device complexity and manufacturing cost increase
Solution Approach 1:
The authentication data, including encrypted identifiers and usage counters, is pre-programmed into the memory device during manifold manufacturing. This preliminary action ensures that security credentials are already in place before the manifold is deployed, eliminating the need for complex real-time authentication hardware while maintaining system security through pre-validated cryptographic credentials.
3Reliability
If the manifold is designed as single-use and disposable, then safety and contamination prevention are improved, but the loss of substance and environmental impact worsen
Solution Approach 1:
The manifold incorporates a reusable housing that can be sterilized and reconfigured, while only the internal filter element and sealing components are discarded after single use. This selective discarding approach maintains contamination prevention by ensuring the critical contact surfaces are replaced, while reducing material waste by preserving the structural housing for multiple cycles after appropriate reprocessing.

AI summary
A method of manufacturing a surgical waste collection manifold with a volume collected datum and a rover type to ensure compatibility with a surgical waste collection rover is provided. The method includes obtaining a second manifold having a second housing defining a surface, the housing defining a second manifold volume and a second outlet opening in fluid communication with the second manifold volume, and coupling a second circuit to the surface of the second manifold, comprising a second memory device including a third memory bank and a fourth memory bank, the third memory bank including a fifth memory field and the fourth memory bank including a sixth memory field. The method may further include programming the fifth memory field with an encrypted first hash digest based on the rover type and programming the sixth memory field with an encrypted second hash digest based on the volume collected datum.
