Integrated PEP and Suction Respiratory Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients with severe airway clearance issues face challenges in self-administering respiratory treatments due to the need to manage phlegm expulsion, device contamination, and interruptions in breathing rhythms, which limits the effectiveness of Positive Exhalation Pressure (PEP) device usage.
Innovation Solution
A PEP device integrated with a suction adaptor that allows for external phlegm elimination via a flexible suction catheter and vacuum unit, enabling self-administered respiratory treatments without interrupting breathing rhythms and reducing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate vacuum unit is used to remove phlegm, then phlegm can be effectively removed from airways, but device complexity increases and treatment time is lost due to switching between devices
Solution Approach 1:
The patent combines the PEP device and vacuum suction unit into a single integrated respiratory treatment device. The vacuum suction unit is housed within the same device body as the PEP mechanism, allowing both functions to be performed without switching between separate devices. This integration maintains effective phlegm removal capability while reducing device complexity and eliminating the need to switch between separate PEP and vacuum units during treatment.
Solution Approach 2:
The integrated device performs multiple functions within a single unit: it provides both Positive Exhalation Pressure (PEP) therapy for airway clearance and vacuum suction for phlegm removal. The device can operate in different modes (PEP only, suction only, or combined) to address various respiratory treatment needs, making it a universal solution that eliminates the need for separate specialized devices.
2Reliability
If a separate vacuum unit is used to remove phlegm, then phlegm can be effectively removed from airways, but treatment time increases due to switching between devices
Solution Approach 1:
By merging the PEP device and vacuum suction unit into a single integrated unit, the patent eliminates the time required to switch between separate devices. The suction function is immediately available within the same device body, allowing phlegm removal to occur without interruption to the breathing rhythm and without the time loss associated with transferring between separate vacuum and PEP units.
3Productivity
If PEP device is contaminated with mucus, then treatment can continue, but device function may cease or require intensive cleaning to prevent bacterial growth
Solution Approach 1:
The patent extracts the suction function as a separate, integrated subsystem that can remove phlegm and mucus from the PEP device interior. The vacuum suction unit can draw contaminants from the PEP chamber and mouthpiece areas, preventing accumulation that would lead to contamination and potential bacterial growth, thereby maintaining device function and reducing the need for intensive cleaning.
Solution Approach 2:
The integrated suction system provides continuous feedback by monitoring and removing contaminants from the device interior. This prevents the buildup of mucus and phlegm that would otherwise contaminate the PEP device, allowing treatment to continue uninterrupted without compromising device reliability or requiring frequent cleaning cycles.
4Device complexity
If patient manages phlegm expulsion manually, then no additional devices are needed, but treatment rhythm is interrupted and aspiration risk increases
Solution Approach 1:
The integrated device enables self-service phlegm removal through the built-in vacuum suction unit. Patients can independently manage their own phlegm expulsion without requiring external assistance or manual manipulation, maintaining treatment rhythm continuity. The device automatically suction removes phlegm from the airways and mouthpiece area, eliminating the need for patients to manually manage phlegm while preserving the rhythmic breathing pattern essential for effective PEP therapy.
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
Enables patients to complete self-administered respiratory treatments safely and effectively, preventing aspiration and maintaining treatment rhythm, while minimizing device contamination and complexity.
Implementation Method 1
a vacuum unit that draws the phlegm through a suction catheter
Implementation Method 2
it helps strengthen the patient's lungs and second, it clears the phlegm and mucus from the to the patient's airways. This is accomplished with the patient undergoing separate regimens of positive exhalation pressure (PEP) treatments
