Extraction Arm Filter Housing for Hygienic Suction Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extraction devices face challenges in maintaining the cleanliness and hygiene of suction pipes, especially when dealing with bioactive pollutants like viruses and bacteria, as they require frequent cleaning or disinfection to prevent health risks.
Innovation Solution
An extraction arm with a suction pipe and a filter housed within the suction path, allowing for easy replacement of the filter to maintain a clean suction path, potentially eliminating the need for frequent cleaning or disinfection, and ensuring the suction pipe remains germ-free.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter system is located in the extraction device, then the extraction device can filter pollutants, but the suction pipe becomes soiled and requires frequent cleaning or disinfection
Solution Approach 1:
The filter is extracted from the extraction device and placed within the suction path instead. This allows the filter to be positioned upstream, filtering pollutants before they reach and soil the suction pipe, thereby maintaining filtration effectiveness while eliminating the need for frequent cleaning or disinfection of the suction pipe.
2Productivity
If the suction pipe is exposed to pollutants, then the extraction device can function, but the suction pipe becomes soiled and poses health risks
Solution Approach 1:
The filter acts as an intermediary element placed within the suction path. It intercepts and removes pollutants from the air stream before the air enters the suction pipe, thereby maintaining extraction productivity while preventing health risks associated with bioactive pollutants depositing on the suction pipe.
3Object-affected harmful factors
If the suction pipe requires frequent cleaning or disinfection, then health risks can be managed, but maintenance time and costs increase
Solution Approach 1:
The filter performs preliminary action by removing pollutants from the air stream before the air reaches the suction pipe. This preliminary filtration prevents pollutant deposition on the suction pipe, thereby controlling health risks while eliminating or significantly reducing the need for subsequent cleaning or disinfection maintenance activities.
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
The use of an exchangeable filter within the suction path enhances the extraction arm's capacity, reduces maintenance intervals, and increases confidence in the medical extraction device by ensuring continuous filtration of pollutants, thereby maintaining a clean and hygienic environment.
Implementation Method 1
a filter system is usually provided, which is located in the extraction device. Extracted air containing pollutants is then fed to the extraction device by means of the suction pipe and filtered there

AI summary
An extraction arm for an extraction device includes a suction pipe and a suction head and defines a suction path that extends from an extraction region in the surroundings of the suction head through the suction pipe to the extraction device. The extraction arm includes an exchangeable filter which is arranged within the suction path. The filter is located in a filter housing which has a main body and a closable cover. The filter is exchangeable, which makes it very easy to prepare the extraction arm for a new application. Since the filter is arranged in front of the suction pipe, the suction pipe remains clean. The filter can easily be changed, whereby disinfection or cleaning of the suction pipe is not necessary.
