Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical sensor attachment devices for respiratory monitoring often obstruct nasal passages and interfere with fluid delivery in patients, requiring frequent adjustments and manual checks, especially in unconscious or semi-conscious individuals.
Innovation Solution
A connection assembly that integrates respiration sensors with nasal cannulas or masks, featuring parallel nasal exhalation flow passages and inhalation flow paths to minimize interference, allowing continuous monitoring while maintaining fluid delivery, with adjustable straps and bands for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate sensor device and fluid delivery device are used, then respiration monitoring and fluid delivery functions are achieved, but device complexity increases and requires frequent manual adjustment
Solution Approach 1:
The patent combines the respiration sensor device and fluid delivery device into a single integrated assembly where the sensor housing and fluid delivery components work together as one unit. This merging eliminates the need for separate devices and reduces manual adjustment requirements while maintaining both monitoring and fluid delivery functions.
Solution Approach 2:
The integrated device performs multiple functions simultaneously - it monitors respiration through the sensor element while also delivering fluid through the same housing structure. The universal design allows the device to serve both as a monitoring tool and a fluid delivery system, reducing overall system complexity.
2Measurement precision
If sensor device is positioned on patient's face, then respiration measurement is enabled, but may obstruct nasal passages and interfere with fluid delivery
Solution Approach 1:
The sensor element is positioned in a specific location within the housing that allows it to measure respiration while minimizing obstruction of nasal passages. The local quality of the sensor placement is optimized to capture breath signals without blocking the patient's airway or interfering with fluid delivery to the nasal cavity.
Solution Approach 2:
The patent positions the sensor element in a three-dimensional arrangement that separates the measurement function from the potential obstruction. By orienting the sensor in a specific spatial dimension relative to the nasal passages, the system achieves measurement capability without direct obstruction of the airway or fluid delivery paths.
3Reliability
If nurse manually places and adjusts separate sensor and fluid delivery devices, then proper positioning is achieved, but time consumption and labor requirements increase
Solution Approach 1:
By integrating the sensor and fluid delivery components into a single assembly, the patent reduces the number of separate positioning operations required. The unified device can be placed and adjusted as one unit, significantly reducing the time and labor needed compared to manually positioning separate devices while maintaining positioning accuracy.
4Reliability
If nurse frequently checks sensor placement and movement, then interference with fluid delivery is prevented, but productivity decreases
Solution Approach 1:
The integrated design ensures that the sensor and fluid delivery components are fixed in a predetermined non-interfering relationship, eliminating the need for frequent checks. The unified structure prevents relative movement between components, allowing the nurse to focus on patient care without repeatedly verifying device positioning.
