Drainage Container Channel Filter Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drainage container devices with suction connections in the lid require frequent disconnection and reconnection of hoses, leading to inefficiencies and risks of incorrect connections, and filters exposed to body fluids become clogged quickly, reducing suction power.
Innovation Solution
A drainage container device with a one-piece lid and a channel connecting the suction bag to the suction port, featuring a protective element in a chamber that prevents overflow and contamination, allowing for easy filter installation and splash protection, enabling cost-effective and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the suction connection is located in the lid, then the drainage container can be evacuated first followed by the suction bag, but both the drainage tube connection and the connection to the vacuum source must be disconnected when changing the bag, which is time-consuming and carries the risk of incorrect connections
Solution Approach 1:
The suction connection is separated from the lid and relocated to the rigid drainage container body. This segmentation allows the lid and suction bag to be changed independently without disconnecting the vacuum source connection, thereby reducing time loss and operational complexity.
2Length of moving object
If the suction connection is located in the lid, then the channel can be shorter, but the filter is exposed to splashes of bodily fluids and becomes clogged quickly, reducing suction power
Solution Approach 1:
A protective cap is introduced as an intermediary element that covers the filter located in the channel. This cap prevents bodily fluids from reaching the filter, avoiding clogging and maintaining suction power, while the channel remains relatively short to minimize fluid exposure pathways.
3Reliability
If a U-shaped cross-section filter is used to protect the vacuum source, then the vacuum source is protected from overflow, but the filter becomes complex and expensive to manufacture
Solution Approach 1:
Instead of using a complex, expensive U-shaped filter, a simple protective cap is employed that can be easily manufactured and disposed of. This cap provides sufficient protection for the vacuum source without requiring complex filter geometries, thereby reducing manufacturing costs and complexity.
4Reliability
If a multi-part lid with a flat filter is used, then the filter is protected from splashes, but the lid becomes complex to manufacture and assemble
Solution Approach 1:
The protective cap is integrated with the channel structure to form a combined protective covering. This merging eliminates the need for separate multi-part lid constructions with embedded filters, simplifying both manufacturing and assembly while maintaining filter protection from splashes.

AI summary
The invention relates to a drainage container device for collecting aspirated bodily fluids using a vacuum source, comprising: a drainage container (3) with a suction connection (30) for connecting to said vacuum source; a substantially single-piece container cover (1) for closing and opening said drainage container (3), and that has a drainage connection (13) for connecting to a patient-side drainage line; a suction pouch (2) for receiving the aspirated bodily fluid, arranged on the container cover (1) and received by the drainage container (3); a channel (6) that at least partially extends through the container cover (1) and that connects an interior space of the suction pouch (2) to said suction connection (30) via an interior space of the drainage container (3) and is otherwise closed, and a protection element (4), particularly a filter, for avoiding overflow and/or contamination of the vacuum source with aspirated bodily fluid. According to the invention, the protection element (4) is located in the channel (6), and a chamber (14) with the protection element (4) arranged therein is present in said channel (6). This device allows simple assembly of a cost-effective filter, with preferred embodiments additionally offering spray protection.
