Removable Ventilator Gas Sensor Holder for Airtight Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilators face challenges in easily mounting and disassembling gas sensors for maintenance, cleaning, or repair without requiring the removal of the housing.
Innovation Solution
A holder with a base body that includes an attachment section for securing to the ventilator housing, a gas inlet, a gas outlet, and receptacles for accommodating the coupling device and gas sensor, forming a breathing gas chamber for easy installation and airtight connection, with screw or snap-lock mechanisms for attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gas sensor is integrated into the ventilator housing, then the oxygen calibration module can determine oxygen concentration in the breathing gas flow, but the gas sensor becomes difficult to remove for maintenance, cleaning, or repair without removing the housing
Solution Approach 1:
The holder is designed as a separate, removable component that can be detached from the ventilator housing without removing the housing itself. This segmentation allows the gas sensor and its mounting structure to be independently accessed, removed, and serviced while maintaining the integrated function within the housing during operation.
Solution Approach 2:
The holder acts as an intermediary component between the gas sensor and the ventilator housing. It provides a mounting interface that enables the gas sensor to be securely installed in the housing while also facilitating easy removal for maintenance, thus mediating between the need for integrated operation and accessible maintenance.
2Ease of repair
If the gas sensor is easily removable from the housing, then maintenance and cleaning become simple, but the connection may compromise the airtightness and operational integrity of the ventilator
Solution Approach 1:
The holder is pre-configured with integrated sealing elements and mounting features that ensure airtight connections are established before the gas sensor is installed. The sealing structures are built into the holder design, so that when the holder is attached to the housing and the gas sensor is mounted on the holder, the airtight connection is automatically established without requiring additional sealing steps.
3Ease of operation
If the holder includes multiple receptacles for coupling device and gas sensor, then the gas sensor can be securely positioned and connected, but the device complexity increases
Solution Approach 1:
The holder merges multiple functions into a single integrated component: it provides the mounting interface to the housing, contains the coupling device receptacle for fluidic connections, and includes the gas sensor receptacle for secure positioning. By combining these separate functions into one unified holder structure, the overall device complexity is reduced while maintaining ease of operation.

AI summary
A holder for attaching a gas sensor to and/or in a housing of a ventilator which comprises a base body having an attachment section for attaching the base body to and/or in the housing, a gas inlet, a gas outlet, a first receptacle for accommodating a coupling device such that an exit opening in the coupling device is fluidically coupled to the gas inlet, and a second receptacle for accommodating the gas sensor, the base body delimiting, together with the gas sensor accommodated by the second receptacle, a breathing gas chamber connected to the gas inlet and the gas outlet such that when the coupling device is accommodated by the first receptacle, breathing gas can flow from the exit opening via the gas inlet into the breathing gas chamber and from there via the gas outlet into an environment of the base body.
