Measurement Probe Hygiene via Detachable Quartz Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement probes for detecting advanced glycation endproducts (AGEs) in biological samples lack a hygienic configuration, requiring frequent cleaning with alcohol and posing hygiene risks during use.
Innovation Solution
A measurement probe with a radiating portion, a light-receiving unit, a support member, and a transparent protective member with a detachable quartz plate that prevents direct contact with the sample, ensuring easy hygiene maintenance and reducing stray light interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the measurement probe front end directly contacts the biological sample for fluorescence measurement, then measurement accuracy is improved, but hygiene is compromised and cleaning is required
Solution Approach 1:
A transparent protective member (cover) is introduced as an intermediary between the measurement probe front end and the biological sample. This cover allows excitation light to pass through and enables fluorescence measurement while preventing direct contact and contamination, thus maintaining both measurement accuracy and hygiene
Solution Approach 2:
The measurement probe front end is divided into separate functional zones: a light transmission zone (transparent protective member) that interfaces with the sample and a measurement zone (light-receiving unit) that remains protected. This segmentation allows the probe to maintain hygiene while performing accurate measurements
2Object-affected harmful factors
If the measurement probe front end is cleaned with alcohol after each use, then hygiene is maintained, but measurement accuracy may be affected by residual cleaning agents
Solution Approach 1:
The transparent protective member serves as a disposable or replaceable intermediary that can be easily cleaned or replaced without affecting the permanent components of the measurement probe. This eliminates the risk of cleaning agents affecting measurement accuracy while maintaining hygiene
Solution Approach 2:
The transparent protective member can be designed as a disposable component that is replaced rather than repeatedly cleaned, eliminating the risk of residual cleaning agents affecting subsequent measurements while maintaining strict hygiene standards

AI summary
Provided is a measurement probe of which hygiene can be easily secured. The measurement probe (1) receives fluorescence emitted by radiation of excitation light to a fingertip (90). The measurement probe (1) includes: a radiating portion that radiates the excitation light; a light-receiving portion that receives the fluorescence; a sleeve (16) disposed at a front end portion of the radiating portion or the light-receiving portion; and a transparent quartz plate (15) disposed at a front end surface (14I) of the radiating portion or the light-receiving portion. The sleeve (16) is provided with an opening in which the quartz plate (15) is detachably mounted.
