Multi-Container Suction Pump System for Simultaneous Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current suction pump systems are inadequate for simultaneously suctioning body fluids from multiple locations, as they often lead to hose blockages due to branched connections and require multiple devices, increasing treatment costs and operational complexity.
Innovation Solution
A suction pump system with multiple fluid collection containers and corresponding drainage hoses, allowing for simultaneous suction from different body locations without the need for Y-connectors, and featuring a single or multiple pump units with dedicated vacuum lines and control electronics for each container, enabling flexible and efficient fluid collection and monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single pump is used with a branched hose to suction from multiple locations, then device complexity is reduced, but the hose becomes more prone to blockages at the Y-connector
Solution Approach 1:
The patent divides the single suction system into multiple independent suction paths, each with its own pump unit and collection container. This segmentation eliminates the Y-connector and branched hose configuration, allowing each drainage hose to connect directly to its own pump unit, thereby preventing blockages at connection points while maintaining manageable system complexity through modular design
2Reliability
If multiple separate suction devices are used to suction from different locations, then hose blockage risk is reduced, but treatment cost and operational complexity increase
Solution Approach 1:
The patent combines multiple pump units and collection containers into a single integrated housing structure. The housing accommodates multiple pump units arranged side-by-side, with each having its own control electronics and display. This merging approach maintains the reliability benefits of separate suction paths while consolidating the system into one operable unit, reducing the number of separate devices nursing staff must manage
Solution Approach 2:
The housing serves multiple functions: it contains and protects multiple pump units, provides mounting structures for all components, offers integrated power supply connections, and houses the control electronics and displays for all pump units. This multi-functionality reduces the need for additional supporting structures and simplifies the overall system configuration
3Quantity of substance
If multiple fluid collection containers are added to the housing, then the capacity for body fluid collection is increased, but the housing size and weight increase
Solution Approach 1:
The patent positions the collection containers within or adjacent to the housing structure in a space-efficient arrangement. The containers are configured to nestle into available spaces within the housing footprint, utilizing vertical and lateral space optimization. This nesting approach maximizes fluid collection capacity while minimizing the overall housing volume and weight increase
