Respiratory Control Unit Sleep Detection Therapy Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inhalable therapy techniques often fail to deliver medication effectively during sleep due to manual activation requirements, leading to missed doses and worsened symptoms upon waking for patients with conditions like COPD.
Innovation Solution
A control unit for a respiratory assist device that automatically triggers the delivery of inhalable therapy based on detection of sleep onset, using predefined time intervals or sleep stages, ensuring continuous relief without disturbing the patient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual activation of inhalable therapy is used, then the subject can control when therapy is delivered, but the therapy is often missed during sleep and symptoms worsen upon waking
Solution Approach 1:
The control unit is pre-programmed with scheduled times for inhalable therapy delivery. The system automatically executes therapy delivery at these predetermined times without requiring manual activation, ensuring consistent therapy administration even during sleep periods when the subject would otherwise not activate the device.
Solution Approach 2:
The system performs self-monitoring and self-execution of therapy delivery based on pre-set parameters. The control unit automatically determines when therapy should be delivered and activates the inhalable therapy device without human intervention, making the system serve itself rather than requiring continuous manual operation by the subject.
2Reliability
If frequent manual activation is required, then therapy effectiveness is maintained, but it interrupts sleep and prevents rest
Solution Approach 1:
The optimal therapy delivery times are determined and programmed in advance before sleep occurs. This preliminary configuration allows the system to automatically deliver therapy at the most effective times without requiring the subject to be awake or actively engage with the device, thus maintaining both effectiveness and sleep continuity.
Solution Approach 2:
The system incorporates sensors that monitor the subject's respiratory parameters and sleep state. This feedback allows the control unit to automatically adjust and optimize therapy delivery timing based on real-time physiological data, ensuring effective symptom relief while minimizing disturbances to sleep patterns.
3Reliability
If inhalable therapy is delayed until peak effectiveness time, then symptom relief is optimized, but the delay reduces responsiveness to acute symptoms
Solution Approach 1:
The system employs periodic therapy delivery at multiple scheduled intervals rather than a single delayed dose. By distributing therapy administration across several time points including before sleep, during sleep, and upon waking, the system maintains continuous therapeutic effect without requiring long delays between doses, thus optimizing relief while maintaining responsiveness.

AI summary
There is provided a control unit (100) for use with a respiratory assist device (102) that assists a subject (104) with respiration. The control unit (100) configured to detect a time at which delivery of an inhalable therapy to the subject (104) is manually triggered on an inhalable therapy device (106). The control unit (100) is also configured to detect whether the subject (104) has fallen asleep and, on detecting that the subject (104) has fallen asleep, control the inhalable therapy device (106) to automatically trigger delivery of the inhalable therapy to the subject (104) at least a predefined length of time following the detected time at which delivery of the inhalable therapy to the subject (104) is manually triggered.
