Rotational Fluid Collection Container for Portable Suction Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable suction pump systems face issues with fluid collection container contamination during tipping movements and difficulty in releasing the container due to residual underpressure, leading to increased force requirements and inefficient disposal practices.
Innovation Solution
A portable suction pump unit design featuring a fluid collection container with a rotationally releasable connection to the pump module housing, allowing for easy attachment and detachment without tilting, thus minimizing fluid sloshing and escape, and enabling easy handling even with residual vacuum, using a leaktight suction line connection that eliminates the need for external hoses and simplifies production with integral fixing elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fluid collection container is connected to the pump module housing using conventional fixing mechanisms, then the connection is secure, but the container cannot be easily released due to residual underpressure requiring considerable force
Solution Approach 1:
The connection mechanism transitions from a static fixed state to a dynamic release state through rotational movement. The container can be easily detached by rotating it approximately 45 degrees, converting the static suction connection into a disconnected state without requiring force to overcome residual underpressure.
Solution Approach 2:
The suction connection is segmented from the main container body through a separate rotatable connection element. This allows the connection to be independently controlled and released without affecting the entire container structure or requiring forceful separation against vacuum pressure.
2Ease of manufacture
If the fluid collection container is designed for disposable use to simplify disposal, then production costs are reduced, but the connection mechanism must be simple and inexpensive
Solution Approach 1:
The connection mechanism is merged into the container lid structure rather than being a separate component. The rotatable connection element is integrated into the lid, eliminating the need for additional fixing elements and reducing overall manufacturing complexity while maintaining secure connection during use.
Solution Approach 2:
The container lid serves multiple functions: it closes the container, provides the rotatable connection to the pump module, and enables easy release through rotation. This multi-functionality eliminates the need for separate disposal mechanisms and simplifies the overall structure for disposable use.
3Ease of operation
If the suction connectors are positioned to allow easy connection, then assembly is simplified, but tilting movements during connection can cause fluid contamination
Solution Approach 1:
The connection process uses controlled rotational movement instead of tilting. The container is rotated approximately 45 degrees to establish or release the connection, preventing fluid sloshing and contamination while maintaining ease of operation. This dynamic approach replaces problematic tilting with a controlled rotational path.

Implementation Method 1
a pump module housing for a pump module and a fluid collection container... for aspirating body fluids and/or air from a patient
Implementation Method 2
The two suction connectors define a common axis... leaktight connection to the pump-side suction connector... when there is still a low underpressure present in the container

AI summary
A portable suction pump unit for aspirating body fluids and/or air from a patient has a pump module housing for a pump module and a fluid collection container. The pump module housing has a pump-side suction connector, and the fluid collection container has a container-side suction connector for leaktight connection to the pump-side suction connector. The two suction connectors define a common axis. The fluid collection container can be secured on the pump module housing via a repeatedly releasable and restorable connection. This connection is releasable and/or restorable by means of a rotation movement of the fluid collection container relative to the pump module housing about said axis. The suction unit according to the invention is inexpensive to produce and permits an easily manageable connection between housing and container.
