Drainage Pump Unit With Reusable Tube Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drainage pump systems cause unnecessary disturbance to patients as they require removal of drainage tubes from fluid collection containers for emptying, leading to complex structures and high costs due to disposable nature.
Innovation Solution
A drainage pump unit design where the drainage tube is securely attached to the pump housing, allowing the fluid collection container to be emptied or replaced without removing the tube, which remains inserted, minimizing patient disturbance and enabling reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drainage tube is made removable from the fluid collection container for emptying, then the container can be emptied, but the patient is disturbed unnecessarily and the structure becomes more complex
Solution Approach 1:
The system is divided into three independent components: the drainage tube with patient-side attachment part, the fluid collection container, and the pump housing with pump-side attachment part. This segmentation allows the container to be emptied or replaced while the tube remains connected to the patient, eliminating the need to remove the tube and reducing patient disturbance.
Solution Approach 2:
The drainage tube is extracted from the fluid collection container and reattached to the pump housing. This extraction eliminates the dependency between the tube and container, allowing the container to be emptied or replaced independently without disturbing the patient connection.
2Reliability
If disposable drainage tube units are used, then incorrect manipulations are avoided, but operating expenses increase due to continuous replacement
Solution Approach 1:
The drainage tube is designed to be reusable and recoverable. After the fluid collection container is emptied or replaced, the tube remains in place and can be reused with the next container. This eliminates the need to discard the tube after each use, significantly reducing operating expenses while maintaining safety through the attachment part design.
Solution Approach 2:
The drainage tube is designed with universal compatibility to work with multiple fluid collection containers. The attachment parts are designed to accommodate different container types, allowing the same tube to serve multiple functions across different containers rather than being single-use.
3Ease of operation
If the drainage tube remains inserted in the pump housing, then patient disturbance is minimized, but the tube must be securely held in place
Solution Approach 1:
The pump-side attachment part serves as an intermediary component between the drainage tube and the pump housing. This attachment part provides a secure retention mechanism for the tube while allowing the fluid collection container to be freely exchanged. The attachment part acts as a mediator that maintains tube stability without requiring direct integration with the container.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces patient disturbance by allowing continuous operation without tube removal, lowers operating expenses through reduced device rental time, and facilitates easy replacement of fluid collection reservoirs, enhancing mobility and cost-effectiveness.
Implementation Method 1
With an underpressure being generated in the fluid collection container by means of the suction pump or vacuum pump, the fluid or secretion from a cavity in the patient is aspirated through the drainage tube and into the collection container

AI summary
The drainage pump unit according to the invention for aspirating body fluids by means of a suction pump comprises a drainage pump device with a pump housing (4) for receiving the suction pump, and a fluid collection container (5) that can be secured releasably on the pump housing (4). The drainage pump unit also comprises a pump-side attachment part (2) which has a connection element for connection to a patient-side drainage tube (10). The attachment part (2) is held releasably on the pump housing (4). This drainage pump unit allows the fluid collection container to be replaced without removing the drainage tube and, therefore, without disturbing the patient.
