Ventilation treatment device and ventilation-control method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation-treatment apparatuses face issues with reliability and comfort due to unconscious patient movements during sleep and the need for cumbersome operations to pause and restart treatment, leading to gas leakage noise and discomfort.
Innovation Solution
A ventilation-treatment apparatus with a headrest and patient-interface device featuring valve assemblies that automatically open and close gas holes to maintain gas flow, allowing seamless operation and comfort by eliminating the need for manual adjustments during treatment pauses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the mainframe is shut down and the breathing mask is taken down to pause treatment, then the treatment can be paused, but gas leakage noise occurs and affects the rest of the company
Solution Approach 1:
The system automatically detects patient presence through the valve assembly contact signal and autonomously controls the mainframe to switch between working and standby states, eliminating the need for manual operation and preventing gas leakage noise during patient absence
Solution Approach 2:
The valve assembly contact between the headrest and head band generates an electrical signal that serves as feedback to the mainframe control system, enabling automatic detection of patient presence and triggering appropriate mainframe state changes to prevent noise
2Reliability
If the mainframe is shut down to pause treatment, then treatment can be paused, but the overall comfort of the patient is seriously affected due to tedious operations
Solution Approach 1:
The system uses the valve assembly contact signal to automatically control the mainframe's working and standby states, enabling the treatment system to serve itself by detecting patient presence and adjusting operation mode without manual intervention
Solution Approach 2:
The valve assembly is pre-configured to generate contact signals that trigger mainframe state changes in advance, so when the patient removes the head band, the system is already prepared to switch to standby mode, ensuring seamless treatment pauses
3Adaptability or versatility
If the head band and headrest are separated during sleep, then patient movement freedom is improved, but gas flow is interrupted and treatment reliability deteriorates
Solution Approach 1:
The system automatically detects head band separation through loss of valve assembly contact signal and self-adjusts to standby mode, maintaining treatment readiness while allowing patient movement freedom during sleep
Solution Approach 2:
The system dynamically switches between working and standby modes based on real-time valve assembly contact status, adapting to patient movement during sleep while ensuring treatment can resume immediately when the head band is repositioned

AI summary
A ventilation treatment device and a ventilation-control method are provided. During use, when a headband contacts a headrest, a first valve assembly contacts a second valve assembly to open first air holes and second air holes, thereby communicating a first chamber with a second chamber, such that air from an air source into the first chamber enters the second chamber and further enters a respiratory chamber of a patient connecting apparatus for inhalation by a patient; and when the headband is separated from the headrest, the first valve assembly and the second value assembly are separated to close the first air holes and the second air holes, thereby preventing the air in the first chamber and the second chamber from flowing out through the first air holes and the second air holes, respectively.
