Two-Part Gas Supply Probe for Hygienic Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current probe configurations in anesthesia and ventilator systems do not adequately incorporate hygienic processing, leading to potential contamination risks during the reuse of breathing system components.
Innovation Solution
A two-part probe configuration comprising a probe element and a conduit element, enabling gas exchange and allowing for the transmission of pneumatic and physical situations to sensors while providing a hygienic interface for gas supply and continuation, with features such as a rounded probe head and detachable screw connections to facilitate easy assembly and disassembly for cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the probe is configured as a single integrated component, then the structure is simple and manufacturing is easier, but the probe cannot be separated for hygienic processing
Solution Approach 1:
The probe is divided into two separate components: a probe element and a conduit element. The probe element can be detached from the conduit element, allowing the probe element to be removed for hygienic processing while the conduit element remains in the device. This segmentation enables hygienic processing capability without requiring complete redesign of the entire probe system.
2Reliability
If the probe uses special connection mechanisms for detachment, then hygienic processing is enabled, but special tools are required for assembly and disassembly
Solution Approach 1:
The probe connection is segmented into a detachable interface between the probe element and conduit element. This interface uses a simple bayonet-style coupling that can be connected and disconnected by hand without requiring special tools, enabling easy assembly and disassembly for hygienic processing.
Solution Approach 2:
The connection mechanism is designed to be operated without external tools or assistance. The probe element can be manually inserted into and removed from the conduit element by the user, making the system self-servicing for assembly and disassembly operations.
3Reliability
If the probe is designed as a two-part configuration, then hygienic processing is enabled, but the connection between parts may introduce leakage risks
Solution Approach 1:
The probe is segmented into two parts with a connection interface designed to maintain gas-tight sealing. The interface includes sealing elements that ensure no gas leakage occurs during operation, while still allowing the parts to be detached for hygienic processing.
Solution Approach 2:
A sealing element acts as an intermediary between the probe element and conduit element at the connection interface. This sealing component ensures gas-tight connection while allowing the detachable design needed for hygienic processing.
