Disposable Breathing Device with Integrated Manometer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing breathing assistance devices often require external manometers for pressure measurement, which can be cumbersome, lead to incorrect setup, and increase the risk of dangerous errors due to additional openings and ports, making it difficult to control internal pressure accurately.
Innovation Solution
A completely disposable breathing assistance device with a built-in disposable manometer for continuous pressure measurement and a calibrated pressure relief valve, featuring a specialized supplementary respirable gas inlet design for improved pressure characteristics and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an external manometer is attached to measure internal pressure, then pressure measurement capability is improved, but device complexity and risk of harmful factors increase due to additional openings and ports
Solution Approach 1:
The patent integrates the manometer directly into the breathing assistance device by forming a port in the main tube that provides direct access to the interior space. This merging of the measurement device with the main system eliminates the need for separate external manometers and connecting tubes, thereby reducing the number of components and potential failure points while maintaining pressure measurement capability.
Solution Approach 2:
The patent extracts the pressure measurement function from the complex external manometer system and implements it through a simple integrated port design. This extraction simplifies the overall system by removing unnecessary components (external manometers, connecting tubes, multiple ports) while retaining the essential pressure measurement functionality.
2Measurement precision
If multiple parts and external manometers are used for pressure measurement, then measurement capability is improved, but ease of operation deteriorates due to cumbersome setup and sterilization requirements
Solution Approach 1:
By integrating the manometer port directly into the disposable breathing assistance device, the patent eliminates the need for separate external manometers and connecting tubes. This integration means that when the entire device is disposed of after use, all components including the pressure measurement interface are discarded together, eliminating sterilization requirements and simplifying setup procedures.
Solution Approach 2:
The patent implements a completely disposable device design where the breathing assistance device, including the integrated manometer port, is discarded after a single use. This approach eliminates the need for sterilization of reusable components and reduces setup complexity, as each new device is ready for immediate use without requiring preparation or cleaning of previous components.
3Measurement precision
If additional openings and ports are added for manometer attachment, then pressure measurement is improved, but reliability deteriorates due to increased risk of incorrect setup and dangerous errors
Solution Approach 1:
The patent merges the pressure measurement port with the main tube structure, creating a single integrated opening that provides direct access to the interior space. This design eliminates the need for multiple separate ports and connecting interfaces, thereby reducing the opportunities for incorrect assembly or connection while maintaining reliable pressure measurement capability.

AI summary
A disposable breathing assistance device with manometer for monitoring the pressure within the device is capable of providing CPAP and in some embodiments includes a deflection face to prevent injected jets of supplementary respirable gas from directly striking the patient's mucosa. The breathing assistance device further optionally includes a safety pressure relief valve as an additional safety against overpressure within the device. A specialized supplementary respirable gas inlet provides improved pressure characteristics.
