Solution Overview

Problem

Existing medical implement dispensing and disposal systems are inconvenient as they require separate locations for obtaining and disposing of medical implements, leading to inefficiencies in handling and storage.

Innovation Solution

A medical implement dispensing and disposal system with a dual-chamber design, where a dispensing chamber for sterile implements and a disposal chamber for soiled implements are integrated within an enclosure, allowing for centralized management and separate access points for both functions, optionally housed in a locking enclosure for security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate locations are used for dispensing and disposing of medical implements, then functional separation is achieved, but convenience and operational efficiency deteriorate

Engineering Contradiction:
Improvefunctional separationVSAvoidconvenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent combines the dispensing chamber and disposal chamber into a single integrated container unit. The dispensing chamber contains sterile medical implements while the disposal chamber collects used implements. Both chambers are housed within one container that can be placed at a single location, eliminating the need for separate dispensing and disposal stations while maintaining functional separation through internal chamber division.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If a single integrated system is used for dispensing and disposing, then convenience is improved, but risk of cross-contamination increases

Engineering Contradiction:
ImproveconvenienceVSAvoidcross-contamination risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The container is divided into distinct dispensing and disposal chambers separated by an internal wall. The dispensing chamber maintains sterile implements while the disposal chamber collects used implements. This physical segmentation prevents cross-contamination between clean and soiled areas while allowing both functions to coexist in a single location.

Inventive Principle:
Principle #1Segmentation

3Reliability

If separate containers are used for sterile and soiled implements, then contamination prevention is achieved, but device complexity and space requirements increase

Engineering Contradiction:
Improvecontamination preventionVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The dispensing chamber and disposal chamber are nested within a single outer container structure. Each chamber is a self-contained unit with its own opening, but both are housed within the same protective enclosure. This nesting approach maintains the separation and contamination prevention of separate containers while reducing overall system complexity and space requirements compared to using two fully independent containers.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A medical implement dispensing and disposal system is configured for mounting within an interior of an enclosure having a first opening for receiving soiled medical implements and a second opening for dispensing medical implements. The system comprises a dispensing chamber configured to be substantially enclosed within the interior of the enclosure and removed from the interior of the enclosure. The dispensing chamber is configured to contain medical implements and has an access opening for passage of medical implements from the dispensing chamber. The access opening is positioned for alignment with the second opening of the enclosure to facilitate passage of medical implements from the enclosure. The system further comprises a disposal chamber configured to be substantially enclosed within the interior of the enclosure adjacent the dispensing chamber and removed from the interior of the enclosure. The disposal chamber is further configured to collect soiled medical implements and has an inlet opening for passage of soiled medical implements into the disposal chamber. The inlet opening is positioned for alignment with the first opening of the enclosure to facilitate passage of soiled medical implements into the enclosure.
