Discrete Bioelectrical Impedance Device Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bioelectrical impedance identification devices used in surgery, especially in spinal and neurosurgery, are often cumbersome and difficult to sterilize due to their integral design, leading to increased waste and surgical costs, as they are typically disposable due to the challenge of cleaning and reusing the probe and probe shell after contact with human skin.
Innovation Solution
A discrete bioelectrical impedance identification device is developed with a detachable connection between the control and detection modules, allowing the control module to be reused after disinfection while the detection module is used as a disposable consumable, and the use of different detachable connections (snap, transverse insertion, or threaded) to accommodate various surgical needs and reduce waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bioelectrical impedance identification device is designed as an integral one-piece structure, then the device is complete and functional, but it becomes difficult to clean and sterilize after use, requiring it to be disposable
Solution Approach 1:
The device is divided into two separable modules: a control module containing the control shell and control processing circuit, and a detection module containing the detection shell, probe, and power supply. The detection module can be detached and disposed of after use, while the control module can be reused, thus resolving the contradiction between maintaining complete functionality and enabling easy sterilization.
2Ease of manufacture
If the device is designed as disposable to ensure sterility, then cleaning and sterilization is simple, but it causes large waste and increases surgical cost
Solution Approach 1:
By segmenting the device into reusable control module and disposable detection module, only the detection module that contacts the patient is disposed of, while the expensive control module with electronic circuits is reused. This reduces waste and surgical costs while maintaining sterility requirements.
Solution Approach 2:
The detection module is designed as a disposable component that is discarded after use, while the control module is recovered and reused for subsequent procedures. This selective discarding and recovering approach minimizes waste while ensuring proper disposal of contaminated components.
3Reliability
If the device is designed as disposable, then sterilization is not needed, but it increases surgical cost
Solution Approach 1:
The device is segmented such that only the detection module requiring sterility is disposable, while the control module is reused. This reduces overall surgical costs while maintaining sterility assurance for the patient-contact components.

Function Achieved in This Case
This design enhances the utilization rate of the control module, reduces surgical costs, minimizes waste, and provides a more environmentally friendly solution by allowing the control module to be reused multiple times while the detection module is discarded after use, improving surgical efficiency and reducing surgical costs.
