Hypoxia Treatment Device with Integrated Grip Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable devices for treating oxygen deficiency are cumbersome, require power sources, and have inflow valves that can be obstructed by user grasp, failing to protect against infection spread effectively.
Innovation Solution
A portable hypoxia treatment device featuring a facemask with an outlet valve for positive end-expiration pressure, an inlet valve within a grip to prevent obstruction, and a 360-degree air inlet, along with a method involving adjustable pressure settings and decontamination protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inflow valve is positioned externally on conventional portable devices, then the device structure is simple, but the valve is obstructed by user grasp causing blocked airflow
Solution Approach 1:
The inflow valve is nested within the grip structure itself, specifically positioned in a recess or cavity of the grip. This allows the valve to be protected from obstruction by the user's hand while maintaining a compact, integrated design. The grip serves dual purposes: holding the device and housing the valve mechanism.
2Ease of operation
If conventional portable devices are designed with headgear to hold the device, then the device can be positioned over patient's mouth and nose, but the device becomes cumbersome and requires additional components
Solution Approach 1:
The facemask is integrated directly with the main body of the device, eliminating the need for separate headgear. The device housing itself is shaped and sized to fit over the patient's mouth and nose, combining the support structure and delivery mechanism into a single unified component.
3Object-affected harmful factors
If conventional portable devices are used without decontamination protocols, then the device is simple to use, but infection spread is not protected against
Solution Approach 1:
The device is divided into removable components including the facemask, filter, and valve assemblies that can be easily separated from the main body. This segmentation allows each component to be independently decontaminated or replaced, simplifying the decontamination process while effectively preventing infection spread.
4Duration of action of moving object
If conventional portable devices require power sources and charged batteries, then the device can provide sustained treatment, but the device becomes awkward to use and requires additional components
Solution Approach 1:
The device utilizes the patient's own respiratory effort to drive airflow through the system. The patient's inhalation and exhalation movements automatically operate the valves and move air through the device, eliminating the need for external power sources, batteries, or motorized components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides effective oxygenation by reducing respiratory muscle work, decreasing atelectasis, and improving functional residual capacity, while being intuitive, easy to use, and decontaminate, suitable for treating hypoxia and preventing progression to acute respiratory distress syndrome.
Implementation Method 1
an outlet valve in fluid communication with the facemask... The outlet valve creates a positive pressure within a subject that reduces atelectasis and recruits alveoli
Implementation Method 2
a first airflow path is defined through the inlet valve when the device is in a first configuration... a second airflow path is defined through the outlet valve when the device is in a second configuration
Data Source
