Solution Overview

Problem

Conventional resuscitators lack real-time monitoring and feedback mechanisms, making it difficult for caregivers to avoid over-inflation of lungs, which can lead to pressure damage, gastric distension, and airway complications during resuscitation efforts.

Innovation Solution

A resuscitator equipped with sensors and a processor that continuously monitor parameters such as pressure, flow rate, temperature, and chemical markers in exhaled breath, providing real-time feedback through visual or audible alarms and verbal guidance to ensure optimal ventilation and prevent over-inflation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a mechanical pressure gauge is used to monitor inflation pressure, then pressure measurement capability is provided, but the resolution is limited and continuous monitoring is difficult

Engineering Contradiction:
Improvepressure measurement capabilityVSAvoidcontinuous monitoring capability
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent replaces the mechanical pressure gauge with an electronic pressure sensor that provides continuous, high-resolution digital measurements. This substitution eliminates the limitations of mechanical gauges by using electronic transduction to convert pressure into electrical signals that can be continuously processed and displayed, thereby achieving both precise measurement and continuous monitoring capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a microprocessor as an intermediary between the pressure sensor and the user interface. This intermediary processes the raw sensor data, converts it into meaningful information, and presents it through visual displays and audible alerts, thereby bridging the gap between continuous physical measurement and continuous informational feedback to the caregiver.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If real-time monitoring of multiple parameters is implemented, then ventilation quality is improved, but device complexity increases

Engineering Contradiction:
Improveventilation qualityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a multi-functional microprocessor-based control system that simultaneously monitors multiple parameters (pressure, flow rate, temperature, chemical markers) and performs multiple functions (data acquisition, processing, display, alarm generation). This universal approach consolidates what would otherwise require separate dedicated systems into a single integrated platform, achieving high ventilation quality monitoring while managing device complexity through functional integration.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines multiple sensing functions (pressure sensing, flow rate sensing, temperature sensing, chemical analysis) and their corresponding processing and output functions into a single integrated sensor assembly and control unit. This merging of previously separate components into unified modules reduces overall system complexity while maintaining comprehensive monitoring capabilities.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A resuscitator has a patient airway interface device, a bag, a fluid passage coupled between the bag and patient airway interface device, and a sensor module. The patient airway interface device may be a mask or an endotracheal tube. The sensor module can have a display, at least one sensor coupled to the flow passage and configured to provide a measurement of at least one parameter, and a processor coupled to the display and the at least one sensor. The processor is configured to receive the measurement from the sensor and provide information on the display based on the received measurement. The information may include a current breath rate, a pressure-vs-time curve, and guidance to the user to assist in achieving a target breath rate.
