Solution Overview

Problem

Current methods for cleaning reusable medical/surgical devices, particularly tubular items like endoscopes, are labor-intensive, ergonomically challenging, and prone to errors due to variability in cleaning liquid concentration and waste of additives, with deep sinks causing physical strain and inefficiency.

Innovation Solution

A modular, one-piece sink insert with a calibrated measurement system, electrically powered pumps, and a thermometer, designed to fit standard medical sinks, providing accurate dilution of additives and ergonomic improvements, reducing the need for manual mixing and minimizing additive waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of stationary object

If a deep sink is used to accommodate large medical devices, then the sink can hold large items, but the technician experiences ergonomic problems and physical strain

Engineering Contradiction:
Improvesink capacityVSAvoidtechnician ergonomics
Core Design Contradiction:
Volume of stationary objectVSEase of operation

Solution Approach 1:

The invention divides the cleaning function into two separate components: a deep sink for holding large devices and a portable basin for actual cleaning operations. This segmentation allows the technician to work with the portable basin at an ergonomic height while the deep sink remains available for storing large medical devices that require immersion.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cleaning process is extracted from the deep sink by using a separate portable basin. This extraction allows the cleaning operation to be performed at a convenient height without requiring the technician to bend over the deep sink, thereby resolving the ergonomic problem while maintaining the sink's capacity to hold large devices.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of manufacture

If manual mixing of additives is used to prepare cleaning liquid, then the process is simple, but the concentration accuracy varies and additives are wasted

Engineering Contradiction:
Improvemixing simplicityVSAvoidadditive concentration
Core Design Contradiction:
Ease of manufactureVSMeasurement precision

Solution Approach 1:

The portable basin incorporates an integrated electric pump that automatically draws cleaning liquid from the deep sink and pumps it through the medical device lumen. This self-service mechanism eliminates the need for manual mixing and syringe filling, ensuring consistent additive concentration while reducing technician labor and additive waste.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical process of mixing additives and filling syringes is replaced with an electric pump system. This substitution provides precise control over cleaning liquid delivery, ensuring accurate additive concentration and eliminating the variability and waste associated with manual mixing methods.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If syringe flushing is used to clean device lumens, then the method is straightforward, but the process is labor-intensive and time-consuming

Engineering Contradiction:
Improvecleaning simplicityVSAvoidcleaning efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The portable basin with integrated electric pump performs the flushing operation automatically. The pump draws cleaning liquid from the basin and forces it through the medical device lumen without requiring the technician to manually operate syringes, thereby maintaining operational simplicity while dramatically improving productivity by eliminating repetitive manual actions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The electric pump enables continuous delivery of cleaning liquid through the device lumen, replacing the intermittent manual syringe filling and flushing process. This continuous action maintains the simplicity of the cleaning method while significantly reducing the time and labor required, thereby improving overall productivity.

Inventive Principle:
Principle #20Continuity of useful action

4Weight of moving object

If small syringes are used for copious flushing, then the syringe size is manageable, but the process becomes labor-intensive and additives are wasted

Engineering Contradiction:
Improvesyringe sizeVSAvoidflushing efficiency
Core Design Contradiction:
Weight of moving objectVSProductivity

Solution Approach 1:

The electric pump system in the portable basin performs the copious flushing operation automatically, eliminating the need for multiple manual syringe fillings. This self-service approach maintains the manageability of the system while dramatically improving flushing efficiency by delivering large volumes of cleaning liquid without repetitive manual labor or additive waste.

Inventive Principle:
Principle #25Self-service

AI summary

A sink insert for cleaning medical or surgical devices having lumens includes a basin and at least two pumps. The basin is shaped to be inserted into a sink and to hold cleaning liquid, and includes an additive reservoir integrally formed in its floor, having additive fill lines defining a plurality of pre-calibrated volume measurement areas for measurement of additives. Basin fill lines positioned on one or more side walls of the basin define a plurality of pre-calibrated volume measurement areas for measurement of a liquid filled into the basin to form the cleaning liquid. At least one of the two pumps has an inlet tube for drawing the cleaning liquid from the basin into the pump, and an outlet tube for pressurized output of the cleaning liquid directed to the medical or surgical device. One or more of the pumps is removable from the sink insert.
