Oxygenated Hemoglobin Wound Therapy System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oxygen therapies for wound healing, such as hyperbaric oxygen therapy, face inefficiencies in oxygen absorption by wounds and red blood cells, leading to prolonged healing times due to excess positive pressure restricting blood flow and requiring time to restore pressure or oxygen after leaks.
Innovation Solution
The use of oxygenated hemoglobin, where oxygen is mixed with hemoglobin to form a mixture that is applied to wounds, leveraging hemoglobin's natural oxygen transport mechanism for more efficient oxygen delivery, reducing recovery times and improving wound healing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional hyperbaric oxygen therapy is used to deliver oxygen to wounds, then oxygen therapy benefits are achieved, but oxygen absorption efficiency is low and healing time is prolonged
Solution Approach 1:
The patent uses hemoglobin as an intermediary substance to transport oxygen to the wound site. Instead of delivering pure oxygen gas directly, the system mixes oxygen with hemoglobin (which has high oxygen affinity) to create an oxygen-hemoglobin mixture that can be efficiently absorbed by tissues, thereby accelerating wound healing and reducing treatment time.
Solution Approach 2:
The patent changes the physical and chemical parameters of oxygen delivery by converting it from a gaseous state to a solution containing hemoglobin. This parameter change enables the oxygen to be delivered in a form that mimics natural blood oxygen transport, significantly improving absorption efficiency and reducing healing time.
2Reliability
If excess positive pressure is applied to maintain oxygen therapy, then oxygen delivery is maintained, but capillary blood flow is restricted
Solution Approach 1:
Hemoglobin acts as a mediator that allows oxygen to be delivered at lower pressures. The hemoglobin-oxygen mixture can be administered without requiring excessive positive pressure, thus maintaining reliable oxygen delivery while avoiding capillary restriction and associated harmful effects.
3Quantity of substance
If conventional oxygen therapy is used, then oxygen is provided to wounds, but oxygen absorption by red blood cells is inefficient
Solution Approach 1:
The patent introduces hemoglobin as an intermediary that facilitates efficient oxygen absorption. Hemoglobin has a high affinity for oxygen and can bind and transport it effectively, allowing red blood cells at the wound site to absorb oxygen much more efficiently than from gaseous oxygen alone.
Solution Approach 2:
The patent changes the chemical form of oxygen from free gas to hemoglobin-bound oxygen, which fundamentally alters how oxygen is absorbed by tissues. This parameter change transforms an inefficient absorption process into an efficient one by leveraging hemoglobin's natural oxygen-carrying capabilities.
