Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hyperbaric oxygen treatment apparatuses are bulky, require the entire body to be enclosed, and lack pressure control, making them unsafe and costly for localized treatments like diabetic foot care, with insufficient therapeutic effects due to inadequate pressure levels.
Innovation Solution
A localized topical hyperbaric therapeutic instrument featuring a primary airbag with an oxygen generator and pressure controller, a massage device, heating element, and treatment unit, which provides a controlled hyperbaric oxygen environment (1-10 KPa) combined with massage and thermal therapy, using Chinese herbs for enhanced therapeutic effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bulky hyperbaric oxygen chamber is used for treatment, then the therapeutic effect can be achieved, but the device size becomes large and requires the entire body to be enclosed
Solution Approach 1:
The patent divides the treatment system into a wearable compression garment that applies localized pressure and a separate oxygen delivery system. This segmentation allows the oxygen therapy to be delivered locally to the treatment area without requiring a large hyperbaric chamber, thus reducing device size while maintaining therapeutic effectiveness.
Solution Approach 2:
The patent applies hyperbaric oxygen therapy locally to specific body areas rather than requiring whole-body treatment. The compression garment is designed to apply pressure to specific regions (e.g., limbs, torso) while the oxygen is delivered directly to the compressed area, enabling localized treatment that reduces the overall device footprint.
2Volume of moving object
If a portablehyperbaric oxygen chamber is used, then the device size is reduced, but the patient still needs to be enclosed in a closed oxygen environment which brings unfavorable factors
Solution Approach 1:
The system separates the oxygen delivery function from the compression function, allowing oxygen to be delivered through a controlled interface (mask or nasal cannula) rather than enclosing the entire body in an oxygen-rich environment. This reduces the risk of oxygen poisoning while maintaining the benefits of hyperbaric oxygen therapy.
Solution Approach 2:
The patent delivers oxygen at concentrations and pressures that are sufficient for therapeutic effect but below levels that would cause oxygen toxicity. The controlled pressure range (1-10 KPa) and regulated oxygen flow ensure therapeutic effectiveness while avoiding harmful effects of excessive oxygen exposure.
3Ease of operation
If pleats are arranged at the outlet and entire body of the bag without pressure control system, then the bag can be sealed, but the pressure value cannot be controlled to reach effective therapeutic effects
Solution Approach 1:
The patent incorporates pressure sensors that continuously monitor the pressure within the compression garment and provide feedback to a control system. This closed-loop control ensures that the pressure remains within the therapeutic range (1-10 KPa), maintaining effective treatment while allowing easy donning and doffing of the garment.
Solution Approach 2:
The system automatically adjusts and maintains the optimal pressure range through integrated pressure control mechanisms, eliminating the need for manual pressure regulation by the user. The garment self-regulates pressure to ensure therapeutic effectiveness while remaining easy to operate.
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 instrument safely and effectively delivers hyperbaric oxygen therapy to localized areas, improving tissue oxygenation, wound healing, and reducing toxin generation, while being convenient and cost-effective by maintaining a controlled pressure range and integrating massage and thermal therapy for enhanced treatment outcomes.
Implementation Method 1
the first pressure controller controls an amount of oxygen supplied to the primary airbag by the oxygen generator, and keeps a value of gas pressure in the primary airbag in a range of 1 KPa-10 KPa
Implementation Method 2
the second pressure controller is connected with the air pump and the massage airbag, respectively, so that the value of gas pressure in the massage airbag changes regularly between 0 and 20 KPa
Implementation Method 3
a heating piece, which is arranged in the primary airbag and generates heat
