Inflatable Device for Passive Leg Raise in Shock Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical treatments for shock patients, such as IV fluids, are inefficient in providing blood flow and nutrient exchange to vital organs, and are not suitable for remote or emergency locations where trained professionals may be limited.
Innovation Solution
An inflatable one-time use device that elevates and secures a patient's appendages, providing passive leg raise to enhance venous circulation and core blood flow, utilizing a pre-charged CO2 cartridge for rapid inflation and adjustable to different pressures and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If IV fluids are used to treat shock patients, then fluid volume is provided to patients, but the treatment contributes to hypothermia and cannot provide nutrient exchange
Solution Approach 1:
The patent uses an inflatable device with a gas-filled chamber to elevate the patient's legs. The hydraulic principle is applied through the inflation mechanism that uses gas pressure to lift and position the leg elevation device, providing passive leg raise without requiring IV fluids.
2Quantity of substance
If IV fluids are used to treat shock patients, then fluid replacement is achieved, but nutrient exchange cannot be provided to vital organs
Solution Approach 1:
The patent employs passive leg raise that utilizes the patient's own venous return mechanism to shunt blood to the core. This self-service approach allows the patient's circulatory system to naturally perform nutrient exchange without requiring external IV fluid administration or active pumping mechanisms.
3Reliability
If trained medical professionals perform limb raising in remote locations, then proper shock treatment is provided, but the limited number of professionals reduces treatment availability
Solution Approach 1:
The patent employs a disposable inflatable device that can be quickly deployed by any trained personnel without requiring specialized medical equipment or expertise. The device is designed for single-use in emergency situations, making it widely deployable in remote locations where resources are limited.
4Ease of operation
If a portable inflatable device is used for appendage elevation, then ease of operation and portability are improved, but device complexity increases
Solution Approach 1:
The device comes pre-assembled in a compact bag with all components ready for deployment. The inflatable mechanism is pre-configured and requires only activation by the user, eliminating the need for complex assembly or setup procedures in the field.
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
The inflatable device effectively increases blood circulation and nutrient delivery to vital organs, is portable and easy to use, even in remote locations, and can rapidly initiate passive leg raise, potentially reducing morbidity and mortality rates in shock patients.
