Reusable Medical Test Slide Frame With Position Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical test slide units face inaccuracies in specimen positioning, leading to inefficiencies and contamination during microscopic examination, and are costly due to single-use surface-treated glass with fixed specimen positions.
Innovation Solution
A medical test slide unit with a frame main body featuring position indicating markers and a detachable slide, allowing precise specimen placement and easy identification, reducing contamination and enabling cost-effective reuse of the frame main body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a slide unit with surface-treated glass position identifiers is used, then specimen placement positions can be identified, but the product becomes expensive and must be disposed after single use
Solution Approach 1:
The slide unit is divided into two separate components: a reusable frame main body containing position indicating markers, and a disposable slide for specimen placement. This segmentation allows the expensive marker system to be reused while only the inexpensive slide is discarded, resolving the contradiction between identification precision and manufacturing cost.
Solution Approach 2:
The position indicating markers are extracted from the slide and placed in a separate reusable frame main body. This extraction allows the markers to be reused across multiple slides, eliminating the need for expensive surface treatment on each individual slide while maintaining accurate position identification.
2Ease of operation
If specimen positions are fixed on a glass slide, then placement is simple, but relative positions between specimens cannot be modified and contamination occurs frequently
Solution Approach 1:
The system transitions from fixed specimen positions on glass to a dynamic configuration where slides can be selectively placed and removed from the frame main body. The position indicating markers remain fixed in the frame, while the slide containing specimens can be easily inserted or removed, allowing flexible modification of relative positions without contamination risks.
3Measurement precision
If a complete slide unit with integrated markers is used, then position identification is available, but the entire unit must be replaced after single use increasing costs
Solution Approach 1:
The slide unit is segmented into a reusable frame main body containing the position indicating markers and a disposable slide for specimens. This allows the valuable marker system to be preserved and reused while only the inexpensive slide is discarded, dramatically reducing material waste and operational costs.
Solution Approach 2:
The design enables selective discarding of only the slide portion after use, while the frame main body with position indicating markers is recovered and reused for subsequent slides. This selective discarding approach minimizes material waste while maintaining position identification accuracy.

AI summary
Provided is a medical test slide unit including a frame main body including: a marker part which has a thin plate shape and in which a plurality of position indicating markers are formed longitudinally and transversely; and a border part arranged to surround the marker part, wherein a step is formed between the border part and the marker part to form a seating recess, and wherein a slide, on which a specimen to be examined using a microscope is placed, is selectively seated in the seating recess.
