Ventilation treatment device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation-treatment apparatuses face issues with reliability and comfort during nighttime use due to unconscious patient movements and the need for cumbersome operations to pause and resume treatment, leading to gas leakage noise and discomfort.
Innovation Solution
A ventilation-treatment apparatus featuring a headrest with a first chamber and a patient-interface device with a second chamber, both equipped with valve assemblies that open and close to control gas flow, allowing seamless communication and prevention of gas leakage when the headband and headrest contact or separate, simplifying operations and enhancing comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the patient pauses treatment by shutting down the mainframe and taking down the breathing mask, then the treatment can be stopped, but gas leakage noise occurs and the operation becomes cumbersome
Solution Approach 1:
The system automatically detects when the patient needs to pause treatment through sensors monitoring patient state, and autonomously controls the valve assembly to close the gas passage and stop gas flow, eliminating the need for manual shutdown operations by the patient
Solution Approach 2:
A valve assembly is introduced as an intermediary component between the mainframe and the patient interface. This valve assembly includes a valve body that can close the gas passage, preventing gas leakage noise when treatment is paused while maintaining the connection between components
2Adaptability or versatility
If the patient turns over or rotates head during sleep, then the patient can change position, but the reliability of ventilation treatment is affected
Solution Approach 1:
The headrest is designed with movable and adjustable components that can dynamically adapt to different patient positions. The valve assembly and gas passage are configured to maintain proper connection and gas flow regardless of head orientation or patient movement during sleep
Solution Approach 2:
The patient interface device is designed to function effectively in multiple patient positions (supine, side-lying, etc.). The gas passage and valve assembly are configured to maintain sealing and flow control across various orientations, making the system universally applicable regardless of patient posture
3Reliability
If the mainframe generates treatment gas continuously, then the ventilation treatment can be maintained, but gas leakage noise disturbs the rest of the family when treatment is paused
Solution Approach 1:
The valve assembly serves as a mediator that controls gas flow between the mainframe and the patient interface. When treatment is paused, the valve body closes the gas passage, blocking gas flow and preventing leakage noise while allowing the mainframe to remain connected and ready for resumption
Solution Approach 2:
The gas flow control function is extracted from the mainframe's continuous operation and delegated to the local valve assembly at the patient interface. This allows the mainframe to maintain readiness while the valve assembly locally prevents gas leakage noise during pauses

AI summary
A ventilation treatment device and a ventilation treatment method. During use, when a headband (22) contacts a headrest (10), a first valve assembly contacts a second valve assembly to open first air holes (12) and second air holes (222), thereby communicating a first chamber (11) with a second chamber (221), such that air from an air source into the first chamber (11) enters the second chamber (221) and further enters a respiratory chamber of a patient connecting apparatus (20) for inhalation by a patient; and when the headband (22) is separated from the headrest (10), the first valve assembly and the second value assembly are separated to close the first air holes (12) and the second air holes (222), thereby preventing the air in the first chamber (11) and the second chamber (221) from flowing out through the first air holes (12) and the second air holes (222), respectively. Thus, when a treatment is suspended, the operations on a host, the patient connecting apparatus (20) and a ventilation pipeline can be omitted, achieving usage and stopping at any time, having simple operation and being easy to use; in addition, the reliability of the ventilation treatment and the comfort during treatment on a patient can also be improved.
