Synchronized HFCWO and MIE Respiratory Therapy Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current respiratory therapy systems for conditions like cystic fibrosis and chronic bronchitis require caregiver assistance and lack efficient synchronization of high frequency chest wall oscillation (HFCWO) and Mechanical Insufflation/Exsufflation (MIE) therapies to effectively clear lung mucus.
Innovation Solution
A respiratory therapy apparatus integrating a high frequency chest wall oscillator and a mechanical insufflator/exsufflator, controlled by a synchronized controller, which applies baseline pressures and oscillations to a patient's torso and airway, respectively, to enhance mucus clearance through coordinated insufflation, exsufflation, and rest cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If HFCWO and MIE therapies are applied separately without synchronization, then each therapy can be delivered independently, but the effectiveness of mucus clearance is reduced and caregiver dependency increases
Solution Approach 1:
The patent combines HFCWO and MIE therapies into a single integrated system with a unified controller that coordinates both therapies simultaneously. The controller synchronizes the HFCWO device (which applies oscillatory pressure to the chest wall) with the MIE device (which provides mechanical insufflation and exsufflation), allowing the therapies to work together synergistically for enhanced mucus clearance without requiring separate caregiver coordination
Solution Approach 2:
The integrated controller serves multiple functions by managing both HFCWO and MIE therapies through a single control unit. This multi-functional approach allows the system to deliver coordinated bronchopulmonary hygiene therapy while reducing the need for multiple separate devices and caregiver interventions
2Extent of automation
If caregiver assistance is required for respiratory therapy, then therapy can be administered manually, but patient independence is reduced and caregiver burden increases
Solution Approach 1:
The integrated respiratory therapy system enables patients to receive coordinated HFCWO and MIE therapies through automated control, reducing dependency on caregiver assistance. The unified controller automatically manages the timing and coordination of both therapies, allowing patients to maintain independence while receiving comprehensive airway clearance treatment
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 apparatus provides a more effective and independent method for airway clearance by synchronizing HFCWO and MIE therapies, enhancing mucus removal and inducing deeper sputum expulsion with reduced caregiver dependency.
Implementation Method 1
The HFCWO therapy may include application to the garment of a first baseline positive pressure and pressure oscillations relative to the first baseline positive pressure
Implementation Method 2
The MIE therapy may include cycles of a positive insufflation pressure and a negative exsufflation pressure applied to the patient's airway
Implementation Method 3
The MIE therapy may include cycles of a positive insufflation pressure and a negative exsufflation pressure applied to the patient's airway
Implementation Method 4
During application of the negative exsufflation pressure to the patient's airway, the controller may signal the HFCWO to apply a second baseline positive pressure to the garment thereby to provide an extra squeeze to the patient's torso

AI summary
A respiratory therapy apparatus includes components operable to simultaneously provide a High Frequency Chest Wall Oscillation (HFCWO) therapy and a Mechanical Insufflation/Exsufflation (MIE) therapy to a patient. The respiratory therapy apparatus includes a controller that controls a synchronization of the HFCWO therapy and the MIE therapy to provide respiratory therapy to the patient to effectively clear mucous or induce deep sputum from the lungs of patient.
