Evaporative Cooling Device for Mammal Heat and Fluid Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for non-invasive anatomical and systemic cooling, fluid removal, and energy extraction from mammals are limited in effectiveness and versatility, particularly in addressing conditions like refractory heart failure, Alzheimer's, and esophageal burn-through during catheter ablation treatments.
Innovation Solution
The method involves blowing dry gas across mucous membranes to induce evaporation, using a device with a conduit system that delivers dry air without a coolant, incorporating heat exchangers to manage heat, and optionally stimulating mucous membranes for increased water production and using negative pressure for improved vasodilation and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If dry gas is blown across mucous membranes to induce evaporation for cooling, then heat and fluid are removed from the body, but the mucous membranes may become over-dried and damaged
Solution Approach 1:
A coolant fluid is introduced as an intermediary substance between the dry gas and the mucous membranes. The coolant fluid absorbs excess heat from the mucous membranes and evaporates, providing cooling protection to the delicate tissue while allowing the dry gas to continue its cooling function. This mediator prevents direct harmful interaction between the dry gas and mucous membranes.
Solution Approach 2:
The system dynamically adjusts parameters including gas flow rate, coolant fluid flow rate, and temperature to optimize cooling effectiveness while preventing mucous membrane damage. By changing these parameters in real-time based on feedback from temperature and flow sensors, the system maintains safe operating conditions.
2Productivity
If high flow rates of dry gas are used to enhance evaporative cooling effectiveness, then more heat is removed from the body, but patient discomfort increases
Solution Approach 1:
The coolant fluid serves as a mediator that enables higher gas flow rates to be used effectively. By providing localized cooling protection to the mucous membranes, the coolant fluid allows the system to operate at higher productivity levels without increasing patient discomfort, thus resolving the contradiction between cooling effectiveness and comfort.
Solution Approach 2:
The system maintains continuous cooling action through the persistent presence of coolant fluid along the gas flow path. This continuous protective action ensures that even at high flow rates, the mucous membranes remain protected, allowing sustained high productivity operation without discomfort.
3Productivity
If the mouth is kept closed during nasal gas delivery to maintain proper airflow, then evaporative cooling works effectively, but the patient cannot speak or eat
Solution Approach 1:
The coolant fluid acts as a protective intermediary that allows the mouth to remain open during treatment. By providing cooling protection to the oral and pharyngeal mucous membranes, the coolant fluid enables patients to speak, eat, and breathe normally while the nasal gas delivery system maintains effective cooling, thus resolving the contradiction between cooling efficiency and ease of operation.
4Temperature
If heat exchangers are added to remove heat from air caused by the desiccant, then the device complexity increases, but the cooling effectiveness is improved
Solution Approach 1:
The system uses the coolant fluid's evaporation process itself to provide cooling, eliminating the need for separate active heat exchangers. The evaporating coolant fluid naturally absorbs heat from the warmed air, providing passive cooling that improves temperature control without significantly increasing device complexity.

Function Achieved in This Case
This approach effectively removes heat and fluid, increases metabolic rate, prevents esophageal burn-through, and potentially delays or ameliorates Alzheimer's onset by utilizing the natural evaporative cooling mechanism to extract energy and fluid from the body.
Implementation Method 1
controlled, induced evaporation of a bodily fluid from a bodily fluid-containing space or surface, such as a mucus containing-space or surface in the mammal
Implementation Method 2
Evaporative cooling is a physical phenomenon in which the evaporation of a liquid results in the cooling of an object or a liquid in contact with it, due to the fact that it requires heat or energy to change a liquid into a gas
Implementation Method 3
the addition of one, two, or more heat exchangers in the device to remove heat from the air caused by the desiccant
Implementation Method 4
providing a source of negative pressure to draw the gas across the mucous membranes (instead of or in addition to pushing it) to promote vasodilation and improve the evaporative model
