Sensor Insertion Device With Real-Time Operability Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sensor inserting devices require unnecessary invasions and cause stress to patients as they do not allow real-time checking of sensor operability before insertion, leading to potential incorrect insertion operations.
Innovation Solution
A sensor inserting device with a signal processor that can be attached to the device main body, allowing for real-time signal transmission and checking of sensor operability before insertion, including an alarming unit to notify users of any issues, thereby preventing the insertion of faulty sensors and ensuring correct operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional sensor inserting device is used without real-time checking capability, then the device structure remains simple, but unnecessary invasions occur and patient stress increases due to inability to verify sensor operability before insertion
Solution Approach 1:
The patent implements preliminary checking of sensor operability through signal transmission between the sensor and signal processor before insertion. The control unit verifies sensor functionality by receiving signals from the sensor while it is still in the holder, allowing verification before the invasive procedure occurs.
Solution Approach 2:
The patent establishes a feedback mechanism where the control unit receives signals from the sensor through the signal processor and provides feedback on sensor operability. This feedback loop enables real-time verification of sensor functionality, allowing the system to indicate whether the sensor is properly functioning before insertion.
2Ease of operation
If sensor checking is performed after insertion using conventional devices, then the insertion procedure is completed, but incorrect operations cannot be detected immediately causing patient stress and requiring removal and reinsertion
Solution Approach 1:
The patent performs the verification action preliminarily by checking sensor operability before insertion rather than after. The control unit is configured to receive and process sensor signals while the sensor is still in the holder, enabling verification before the insertion procedure is completed.
3Reliability
If multiple insertion attempts are made due to undetected sensor issues, then the insertion procedure may eventually succeed, but patient stress and pain increase due to unnecessary invasions
Solution Approach 1:
The patent applies preliminary anti-action by preventing unnecessary insertions through prior verification of sensor operability. The control unit detects sensor functionality issues before insertion occurs, allowing the system to alert the user and prevent the harmful action of inserting a faulty sensor that would cause patient stress and pain.

AI summary
A sensor inserting device includes a device main body and a push handle for moving a detector of a sensor and an insertion needle, with the sensor held coupled to the insertion needle, into the body of a patient. A transmitter, for processing a signal from the sensor, is set in the device main body. A cable, allowing transmission of a signal between the sensor and the transmitter, is connected to the sensor (12) and the transmitter.
