Patient Interface Moisture Extraction for Condensed Water Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current non-invasive positive pressure ventilation devices lack an automatic mechanism to remove condensed water, necessitating active medical intervention, which complicates usage and increases labor intensity.
Innovation Solution
A patient interface apparatus with integrated moisture-extraction parts, including a first moisture-extraction part on the main body and a second moisture-extraction part on the ventilation tube, designed to absorb and evaporate moisture externally, reducing the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gas cavity is provided in the patient interface apparatus to supply gas to the patient, then ventilation treatment can be provided, but water vapor in the inhaled and exhaled gas condenses in the gas cavity, creating excessive condensed water that poses a threat to the patient
Solution Approach 1:
The patent extracts the harmful condensed water from the gas cavity by providing a drainage channel that leads from the gas cavity to the outside of the patient interface apparatus. This allows the condensed water to be removed from the system, eliminating the harmful effect while maintaining the gas cavity's ventilation function.
Solution Approach 2:
The patent introduces a drainage channel as an intermediary element between the gas cavity and the external environment. This mediator provides a controlled pathway for condensed water to exit the gas cavity, preventing direct contact with the patient while safely removing the harmful substance.
2Ease of operation
If no automatic moisture removal function is provided in the patient interface apparatus, then the device structure remains simple, but active intervention of medical staff is required, increasing labor intensity and reducing convenience
Solution Approach 1:
The patent enables the patient interface apparatus to serve itself by providing an automatic drainage mechanism through the drainage channel. The condensed water is removed passively due to gravity and pressure differential, without requiring active intervention from medical staff, thus achieving self-service functionality.
Solution Approach 2:
Instead of actively pumping or heating to remove moisture, the patent inverts the approach by allowing condensed water to naturally drain outward through the drainage channel using gravity and pressure differential. This passive drainage approach simplifies the device structure while improving ease of operation.
3Productivity
If no automatic moisture removal function is provided, then the device structure remains simple, but medical staff intervention is required, increasing labor intensity
Solution Approach 1:
The drainage channel enables the apparatus to automatically manage condensed water without requiring medical staff intervention, thereby improving productivity by reducing the time and labor needed for manual moisture removal while maintaining a simple structural design.
