Solution Overview

Problem

Existing air resuscitation devices require manual expertise to provide repeated air inflows, which can be inadequate for patients in breathing distress, especially in emergency situations where timely and consistent oxygen delivery is critical.

Innovation Solution

An automated air resuscitation device equipped with a fan assembly, a flexible mouth and nasal opening cover, and a controller with a timer and flow controller, which delivers air in a timed and controlled manner, including a pause for air venting to prevent air stagnation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual bag squeezing is used for air resuscitation, then the device structure remains simple, but the reliability of consistent air delivery deteriorates due to operator skill requirements

Engineering Contradiction:

Improveconsistent air deliveryVSAvoiddevice structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The device performs self-service through automated fan control that independently regulates air delivery timing and volume without requiring manual intervention or operator expertise, ensuring consistent air inflow and outflow cycles

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical bag squeezing action is replaced with an automated fan-driven air delivery system controlled by electronic timing circuits, eliminating the need for manual operation while maintaining reliable air delivery

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Quantity of substance

If continuous air inflow is provided to the patient, then oxygen delivery is maximized, but air stagnation and carbon dioxide retention occur

Engineering Contradiction:

Improveoxygen deliveryVSAvoidair stagnation

Core Design Contradiction:

Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The device implements periodic action by automatically cycling the fan between air inflow mode and air outflow mode, creating rhythmic ventilation that delivers fresh oxygen while periodically evacuating stale air and carbon dioxide

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The fan rotation is reversed during the outflow phase to actively exhaust air from the patient's airway, converting the same component into a bidirectional system that both delivers and removes air as needed

Inventive Principle:

Principle #13The other way round (Inversion)

3Reliability

If the fan runs continuously to deliver air, then oxygenation is improved, but energy consumption increases and heat generation occurs

Engineering Contradiction:

ImproveoxygenationVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The fan operates periodically rather than continuously, alternating between inflow and outflow phases with timed pauses, reducing overall energy consumption while maintaining effective oxygenation through rhythmic ventilation cycles

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The device maintains continuity of useful action by ensuring that during each cycle, the fan is actively delivering or evacuating air without idle periods, maximizing the efficiency of each energy input while still providing rest cycles to reduce cumulative energy consumption

Inventive Principle:

Principle #20Continuity of useful action

AI summary

An improved air resuscitation device to provide air to a patient with impaired breathing has a fan assembly and a flexible mouth and nasal opening cover. The fan assembly includes a fan and a motor, one or more batteries to power the fan, a switch to connect to the fan to turn the fan on or off, a controller with a circuit board having a timer and flow controller. The device, when attached to the patient and switched on, powers the fan to deliver air into and through the mouth and nasal opening cover into the patient's airway for a first set period of time and the fan pauses allowing the air to vent out of the fan assembly for a second set period of time and then the fan restarts and pauses repeatedly automatically providing air.
