Disposable Patient Interface with Removable Optical Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patient interfaces with reusable optical sensors are difficult to quickly insert and remove, posing challenges during emergencies where rapid sterilization or cleaning is necessary to prevent infection.
Innovation Solution
A disposable patient interface with a conformal placement element and a shoe that removably mounts a reusable optical sensor, featuring protrusions and apertures for secure locking and an actuator for easy dismounting, along with a compliant structure that conforms to the body without causing wrinkles and an instructional diagram for proper placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the patient interface uses a mechanical coupling mechanism to secure the optical sensor, then the sensor remains firmly attached during use, but the sensor becomes difficult to quickly insert and remove during emergencies
Solution Approach 1:
The patient interface is divided into separate components: a disposable patient interface and a reusable optical sensor. The sensor can be quickly detached from the interface by pulling on a cable or extension, allowing rapid removal for sterilization or cleaning while maintaining secure attachment during use through the mechanical coupling mechanism with protrusions and apertures.
2Reliability
If the patient interface uses a secure mechanical coupling mechanism, then the sensor remains firmly attached, but the time required for sterilization or cleaning increases during emergencies
Solution Approach 1:
The system separates the disposable patient interface from the reusable optical sensor, allowing the sensor to be quickly removed by pulling on a cable or extension. This enables rapid detachment for sterilization or cleaning without time-consuming disassembly, while the mechanical coupling ensures secure attachment during use.
Solution Approach 2:
The patient interface is designed as a disposable component that is discarded after use, while the optical sensor is recovered, sterilized, and reused. This allows the sensor to be quickly removed from the disposable interface for cleaning and sterilization, minimizing time loss during emergency situations.
3Reliability
If the patient interface uses a complex mechanical coupling mechanism, then the sensor attachment is secure, but the device complexity increases
Solution Approach 1:
The mechanical coupling mechanism is simplified through segmentation: protrusions on the sensor align with apertures in the patient interface to create a secure attachment. The cable or extension provides an additional simple detachment mechanism, avoiding complex multi-component coupling systems while maintaining reliability.

AI summary
A disposable patient interface includes a reusable sensor that removably mounts within a shoe of the disposable patient interface when at least one protrusion on opposite ends of the sensor removably lock with corresponding at least one aperture on opposite portions of the shoe. The patient interface includes a compliant structure which conforms to a patient's body upon placement thereon without causing wrinkles in the compliant structure so as to maximize adhesion of the compliant structure against skin on the patient's body when the compliant structure is conformed to muscle underlying skin on the patient's body.
