Dual-Mode Veterinary Hyperbaric Chamber Oxygen Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current veterinary hyperbaric oxygen therapy methods are cumbersome and require the use of masks, hoods, or cages for delivering enriched oxygen gas mixtures to animals, lacking an efficient and adjustable solution for hyperbaric and supplemental oxygen therapy.
Innovation Solution
A dual-mode veterinary hyperbaric chamber system that operates in two modes: one for hyperbaric therapy at elevated pressures and another for delivering adjustable supplemental oxygen at ambient pressure, using a high flow gas mixer to maintain accurate gas mixture concentrations and incorporating an alarm/bypass module for gas supply failures, allowing for emergency venting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If masks, hoods, or cages are used to deliver enriched oxygen gas mixtures to animals, then oxygen delivery can be achieved, but the treatment becomes cumbersome and difficult to operate
Solution Approach 1:
The patent extracts the oxygen delivery function from traditional masks, hoods, or cages and integrates it directly into the hyperbaric chamber environment. The chamber itself becomes the delivery medium, eliminating the need for separate oxygen administration equipment and simplifying the overall treatment process while maintaining effective oxygen delivery to the animal.
Solution Approach 2:
The patent merges the hyperbaric therapy function with supplemental oxygen delivery into a single integrated system. The chamber simultaneously provides both the pressurized environment and the enriched oxygen gas mixture, combining what were previously separate treatment modalities into one unified apparatus that improves ease of operation.
2Reliability
If a dedicated hyperbaric chamber is used for hyperbaric oxygen therapy, then hyperbaric treatment can be provided, but the chamber cannot deliver adjustable supplemental oxygen at ambient pressure
Solution Approach 1:
The patent designs the hyperbaric chamber to perform multiple functions: it can operate in hyperbaric mode for pressurized oxygen therapy and in ambient pressure mode for adjustable supplemental oxygen delivery. This multi-functionality allows a single apparatus to replace what would traditionally require separate equipment, thereby improving adaptability while maintaining hyperbaric therapy effectiveness.
Solution Approach 2:
The patent incorporates dynamic control capabilities that allow the chamber to transition between different operational modes (hyperbaric and ambient pressure) and adjust oxygen concentration levels. This dynamic adaptability enables the system to respond to different treatment requirements, enhancing versatility without compromising the reliability of hyperbaric therapy when that mode is selected.
3Measurement precision
If adjustable enriched oxygen gas mixture delivery is implemented, then oxygen concentration can be controlled, but the system becomes more complex requiring additional equipment
Solution Approach 1:
The patent combines the gas mixing and delivery functions within the existing chamber infrastructure, utilizing the chamber's existing fluid delivery network and control systems. By integrating supplemental oxygen delivery into the hyperbaric chamber's existing architecture rather than adding completely separate equipment, the system achieves adjustable oxygen concentration control while minimizing the increase in overall device complexity.

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 efficient and adjustable delivery of enriched oxygen gas mixtures to animals without the need for masks, hoods, or cages, ensuring safe and effective hyperbaric and supplemental oxygen therapy while providing a failsafe mechanism for gas supply failures.
Implementation Method 1
A high flow gas mixer is utilized to maintain accurate gas mixture concentrations with fluctuating supply pressures of medical air and medical oxygen gases
Implementation Method 2
hyperbaric therapies refer to medical treatments in which the pressure applied to the patient is greater than sea level atmospheric pressure. delivering oxygen under pressure into the chamber
Implementation Method 3
The alarm/bypass module monitors gas supply pressures, sounds an alarm, and bypasses the remaining gas supply in the event of a supply gas failure

AI summary
A system and method of administrating conventional hyperbaric chamber therapy as well as supplemental oxygen therapy at ambient conditions to an animal using a veterinary hyperbaric chamber. The hyperbaric chamber can function in its usual mode of operation; i.e., providing oxygen at greater than atmospheric pressure and also in a second mode of operation to administer supplemental oxygen thereafter at ambient pressure conditions. In the second mode of operation, the method and apparatus may deliver approximately 80 liters per minute continuous flow of 0.21 through 1.0 FI02 adjustable oxygen gas mixture. The mixture is delivered at ambient pressure from one end of the chamber, flows across the animal positioned within the hyperbaric chamber, and exits at the opposite end for exhaust to ambient conditions. A high flow gas mixture is utilized to maintain accurate gas mixture concentrations with fluctuating supply pressures of medical air and medical oxygen gases.
