Integrated Blood Analysis Apparatus with Pressing Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing integrated bodily-fluid-component analyzing apparatuses face challenges in ensuring blood flow from a pricked site, especially in individuals with hypotension or the elderly, leading to low measurement accuracy due to contamination and evaporation issues when the apparatus is removed from the skin.
Innovation Solution
An integrated apparatus with a lancet holder and test strip design that allows for the lancet to be moved back and forth along a predetermined path, incorporating a pressing section to facilitate blood flow from the pricked site without removing the apparatus, ensuring accurate and contamination-free measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the apparatus is removed from the pricked finger to facilitate blood flow, then blood can be obtained through manual rubbing, but the blood sample becomes contaminated and measurement accuracy decreases
Solution Approach 1:
The pressing section is integrated into the apparatus body, combining the blood extraction function and blood flow facilitation function into a single integrated device. This allows the user to press the pressing section to facilitate blood flow without removing the apparatus from the pricked site, preventing contamination and maintaining measurement accuracy.
2Measurement precision
If the apparatus remains in place on the living body, then measurement continuity is maintained, but blood may not flow easily from the pricked site in hypotensive or elderly individuals
Solution Approach 1:
The apparatus provides self-service functionality by including a pressing section that allows the user to facilitate blood flow directly through the apparatus without needing to remove it or use separate manual rubbing actions. The pressing section enables the user to apply pressure to the pricked site to promote blood flow while the apparatus remains in place.
3Reliability
If manual rubbing is performed to facilitate blood flow, then blood can be obtained, but the operation becomes complex and time-consuming
Solution Approach 1:
The pressing section is integrated into the apparatus body, combining the blood extraction function and blood flow facilitation function into a single integrated device. This allows the user to press the pressing section to facilitate blood flow without removing the apparatus from the pricked site, preventing contamination and maintaining measurement accuracy.

AI summary
An integrated bodily-fluid-component analyzing apparatus includes a main body, a lancet holder connected to the main body so as to be movable back and forth along a predetermined movement path, a lancet removably attached to the lancet holder, and a test strip that is removably attached to the main body and is used to measure a component of the bodily fluid flowing from a pricked site of the living body pricked with the lancet. The movement path of the lancet holder and a bodily fluid inlet of the test strip face a specific position that is in a vicinity of the main body and at which the pricked site is to be placed. The apparatus further includes a pressing section that presses a portion of the living body adjacent to the pricked site so as to cause the bodily fluid to flow from the pricked site.
