Glucose Test Pad Spacers for Cleaner Blood Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blood glucose measurement devices are susceptible to user handling errors, leading to inaccurate readings due to contamination and improper application of blood samples.
Innovation Solution
A glucose test arrangement with spacer elements on a supporting member that provide tactile feedback and prevent direct finger contact with the test pad, ensuring that only uncontaminated blood is applied to the receiving area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user directly applies blood sample to the test pad, then the application process is simple and fast, but the measurement accuracy deteriorates due to contamination and improper handling
Solution Approach 1:
The spacer element acts as an intermediary structure between the user's finger and the test pad. It provides a designated contact area that guides proper finger placement while preventing direct contact with the test pad's receiving area, thereby eliminating contamination risks and improper handling without complicating the application process
Solution Approach 2:
The spacer element with tactile feedback features enables the user to self-correct their application technique. The tactile cues guide the user to apply the blood sample correctly without requiring external instruction or supervision, improving measurement accuracy while maintaining ease of use
2Device complexity
If the test pad is directly accessible to the user, then the device structure is simple, but the reliability deteriorates due to user handling errors
Solution Approach 1:
The spacer element serves as a protective intermediary that physically separates the user's finger from the test pad's receiving area. This simple structural addition prevents contamination and improper handling errors while maintaining overall device simplicity
Solution Approach 2:
The spacer element preemptively prevents harmful user actions by blocking direct finger contact with the test pad before contamination or handling errors can occur. The tactile feedback provides early warning to guide correct application technique

AI summary
A glucose test arrangement is provided for use in a handheld meter. The arrangement comprises a disposable test pad responsive to glucose in a body fluid, and a supporting member adapted to support the test pad at an application site for applying body fluid from a user's skin onto a receiving area of the test pad. The receiving area faces away from the supporting member. One or more spacer elements are arranged on the supporting member adjacent to the test pad, wherein the one or more spacer elements have a skin-contacting end section which protrudes above the receiving area.
