Manometer with Cadence Indicator for CPR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CPR systems require caregivers to constantly switch focus between pressure measurement devices and cadence indicators, leading to confusion and inefficiency during emergency procedures, as these components are often separate and distant from each other.
Innovation Solution
Integration of a manometer with a cadence indicator, providing simultaneous pressure readings and cadence feedback through visual or audible signals, such as flashing lights or tones, within a unified housing, allowing caregivers to maintain focus on the patient without needing to look away.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate pressure measurement devices and cadence indicators are used, then each component can be optimized independently, but the caregiver must constantly switch focus between them causing confusion and inefficiency
Solution Approach 1:
The patent combines the pressure measurement device (manometer) and cadence indicator into a single integrated unit. The manometer housing contains both the pressure sensing mechanism and the cadence display components (visual and/or audible indicators), allowing the caregiver to monitor both parameters simultaneously without shifting attention between separate devices.
2Adaptability or versatility
If separate cadence devices are placed at a distance, then device placement flexibility is improved, but the caregiver is forced to look back and forth between the manometer and the distant cadence device
Solution Approach 1:
By integrating the cadence indicator directly into the manometer housing, the invention eliminates the need for separate placement of cadence devices. Both functions are co-located, ensuring that all critical information is available in a single location within the caregiver's immediate view.
3Adaptability or versatility
If multiple separate components are used for CPR monitoring, then functional versatility is improved, but finding separate components during emergency adds to confusion
Solution Approach 1:
The invention consolidates multiple monitoring functions (pressure measurement, visual cadence indication, and audible cadence indication) into a single integrated device. This reduces the total number of separate components the caregiver must locate and manage during an emergency, while maintaining all necessary monitoring capabilities.
Solution Approach 2:
The manometer housing serves multiple functions simultaneously: it houses the pressure measurement mechanism, contains the visual cadence indicator, and incorporates the audible cadence indicator. This multi-functional design allows a single device to provide comprehensive CPR monitoring and guidance.
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 caregivers to maintain proper lung inflation pressure and chest compression cadence concurrently, enhancing the efficiency and accuracy of CPR procedures by keeping critical information readily visible and accessible.
Implementation Method 1
increases in the gas pressure above atmospheric pressure works against the bias of the resilient member, therefore rotating the hub
Implementation Method 2
The hub is biased by a resilient member such that at atmospheric pressure, the pointer indicates a zero reading
Data Source
AI summary
A manometer with a cadence indicator includes a housing and a gas pressure indicator interfaced to the housing. An input port of the housing is for connecting the manometer to a source of gas pressure, such that the gas pressure at the input port is reflected in the gas pressure indicator, providing a pressure reading. A cadence module is interfaced to the housing such that cadence is provided concurrently from the local of the gas pressure indicator. Cadence is provided by a flashing light or audible noise.
