Integrated Ventilator With Pulsed Oxygen Delivery for Dual Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients requiring both mechanical ventilation and supplemental oxygen therapy often rely on multiple machines, reducing independence and increasing logistical burdens due to the need to switch between therapy options.
Innovation Solution
A ventilator system that integrates both ventilation and oxygen therapy capabilities, allowing for flexible therapy options including independent delivery of oxygen pulses, ventilation gases, or simultaneous delivery through separate or combined pathways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple machines (ventilator and oxygen concentrator) are used to provide different therapies, then therapy coverage is complete, but patient independence decreases and logistical burden increases
Solution Approach 1:
The patent combines a ventilator and oxygen concentrator into a single integrated machine. The oxygen concentrator generates oxygen that can be delivered through a first output, while the ventilator delivers ventilatory support through a second output. Both therapies can be administered simultaneously or independently from one device, eliminating the need for patients to manage multiple separate machines and improving ease of operation while maintaining complete therapy coverage.
2Adaptability or versatility
If multiple machines are used to provide ventilation and oxygen therapy, then therapy options are comprehensive, but device complexity increases
Solution Approach 1:
The integrated machine is designed with multi-functionality, serving both as an oxygen concentrator and a ventilator. The system includes an oxygen concentrator portion with a first output for oxygen delivery and a ventilator portion with a second output for ventilatory support. This universal design allows a single device to provide comprehensive therapy options including oxygen-only mode, ventilation-only mode, and combined mode, reducing the number of separate machines needed.
3Measurement precision
If separate oxygen delivery and ventilation pathways are used, then therapy delivery is precise, but system complexity increases
Solution Approach 1:
The system is segmented into distinct functional portions: an oxygen concentrator portion with its own output, and a ventilator portion with its own output. This segmentation allows each component to operate independently with precise control over its specific therapy parameters. The oxygen concentrator can be adjusted for oxygen concentration and flow rate separately from the ventilator's pressure and volume settings, maintaining therapy delivery precision while integrating both functions in one machine.

AI summary
The present technology is directed to ventilator systems that can provide both ventilation therapy and oxygen therapy. The systems described herein may include a ventilation assembly that can provide inspiratory gas to a patient circuit and an oxygen assembly that can provide pulses of oxygen to an oxygen delivery circuit. In some embodiments, the oxygen delivery circuit is distinct from the patient circuit. For example, the patient circuit can include a corrugated conduit coupled a ventilation mask, and the oxygen delivery circuit can include a nasal cannula. The ventilation mask can be positioned over the nasal cannula so that the patient can receive both the inspiratory gases and the pulses of oxygen.
