Sensor-Controlled Respiratory Hood for Infant Oxygen Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oxygen delivery systems for infants and children, such as nasal cannulas and oxygen masks, are uncomfortable and prone to removal, while oxygen tents and hoods are limited to hospital settings and suffer from humidity and gas buildup issues, making them unsuitable for home use.
Innovation Solution
A respiratory treatment system with gas delivery ports that direct therapeutic gases towards a patient without physical contact, using a partial hood for increased oxygen concentration and adjustable design to reduce gas buildup, and sensor-controlled gas flow optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a nasal cannula system is used to deliver oxygen, then precise oxygen control is achieved, but patient comfort deteriorates and removal resistance decreases
Solution Approach 1:
The patent extracts the oxygen delivery function from direct patient contact devices (cannulas, masks) and relocates it to a non-contact hood system. The hood delivers oxygen without requiring tubing or attachments that contact the patient's nose or mouth, thereby maintaining precise oxygen control while eliminating discomfort and removal issues associated with traditional contact-based systems.
Solution Approach 2:
The patent introduces a hood as an intermediary structure between the oxygen source and the patient. This hood acts as a mediator that distributes oxygen throughout the enclosed space, allowing precise oxygen delivery without direct contact with the patient's respiratory tract, thus resolving the contradiction between precision and comfort.
2Reliability
If a nasal cannula system is used, then oxygen delivery is reliable, but skin injury risk increases due to tape burns
Solution Approach 1:
The patent removes the tape and direct contact components from the oxygen delivery system. By extracting the harmful tape attachment method and replacing it with a hood-based non-contact delivery system, reliable oxygen delivery is maintained while eliminating the source of skin burns and irritation.
3Productivity
If an oxygen mask is used, then oxygen delivery is effective, but device complexity and tubing requirements increase
Solution Approach 1:
The patent merges the oxygen delivery function with a hood structure, combining multiple functions (oxygen delivery, patient containment, comfort) into a single integrated system. This eliminates the need for separate tubing, masks, and attachment components, reducing device complexity while maintaining effective oxygen delivery.
4Ease of operation
If oxygen tents or hoods are used, then patient comfort improves, but gas buildup and humidity control become problematic
Solution Approach 1:
The patent implements a dynamic hood system that can be adjusted and positioned to optimize oxygen distribution while preventing gas and humidity buildup. The hood's flexible design allows for proper ventilation and gas exchange, maintaining patient comfort without creating harmful enclosed environments.

AI summary
Embodiments relate to systems and methods for delivery of oxygen or other treatment gases to a patient without requiring physical contact or enclosure of the patient. Embodiments can include a delivery hood, sensing components, and a gas distribution system including one or more gas delivery ports. Gas delivery ports may be individually controlled based on input from the sensing components to alter the volume and orientation of treatment gas flow directed at a patient. Sensing components can include cameras or other sensors that detect the position of a patient's head, and gas delivery ports may then be controlled to direct treatment gas flow in the direction of the patient's head. Embodiments and methods described thereby allow for efficient oxygen or other gas delivery to a patient without requiring contact or enclosure of the patient.
