Blood Sensor Reference Terminal for Automatic Connector Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blood sensors require precise adjustment of their angle of attachment to connect with the connectors of a blood test apparatus, which can be burdensome for diabetes patients, especially those with poor eyesight, due to the need to identify and connect multiple electrodes accurately.
Innovation Solution
Incorporation of a reference terminal with a predetermined electrical resistance or multiple reference terminals connected via a conductor to facilitate automatic identification of connection terminals, eliminating the need for visual adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple connection terminals are provided for working electrode, counter electrode, detecting electrode, and Hct electrode, then the functionality and measurement capability of the blood sensor is improved, but the complexity of aligning and connecting these terminals increases the burden on patients
Solution Approach 1:
The patent divides the connection terminal identification function into separate segments: a reference terminal that is electrically connected to one of the plurality of connection terminals through a conductor with predetermined resistance. This segmentation allows the blood test apparatus to automatically identify each connection terminal's function by measuring resistance from the reference terminal, eliminating the need for patients to manually align multiple terminals.
Solution Approach 2:
The patent introduces a reference terminal as an intermediary element that mediates between the plurality of connection terminals and the blood test apparatus. The reference terminal, combined with conductors having predetermined resistance values, serves as a mediator that enables automatic identification of connection terminal functions, thereby simplifying the attachment operation for patients.
2Reliability
If precise angle adjustment is required for connecting connectors to connection terminals, then the connection reliability is improved, but the attachment process becomes more complex and time-consuming
Solution Approach 1:
The patent enables the blood sensor system to self-identify the functional assignment of connection terminals through electrical resistance measurement from the reference terminal. This self-service mechanism automatically determines which connector connects to which electrode (working, counter, detecting, or Hct), eliminating the need for manual angle adjustment and ensuring reliable connections without increasing operational complexity.
Solution Approach 2:
The patent replaces the mechanical alignment system (requiring precise angle adjustment and visual positioning) with an electrical identification system. By using electrical resistance measurement from the reference terminal, the system automatically identifies connection terminal functions, substituting mechanical precision requirements with electrical measurement capabilities.
3Measurement precision
If visual alignment methods are used to position the blood sensor, then the connection accuracy is improved, but the operation becomes more difficult for patients with poor eyesight
Solution Approach 1:
The patent replaces visual alignment (optical/mechanical system) with electrical resistance measurement. The reference terminal and conductors with predetermined resistance values create an electrical identification system that automatically determines connection terminal functions, eliminating the need for visual alignment and making the operation accessible to patients with poor eyesight.
Solution Approach 2:
The reference terminal acts as an intermediary that bridges the gap between the physical connection terminals and the blood test apparatus. Through electrical resistance measurement, it provides accurate identification of connection terminal functions without requiring visual alignment, thereby maintaining measurement precision while improving ease of operation for patients.
