Blood Collection Cuff and Puncture Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-specialist individuals, such as those undergoing blood collection tests for lifestyle-related diseases, often struggle to collect a sufficient amount of blood efficiently.
Innovation Solution
A blood collection system that includes a puncturing and blood collection mechanism using a puncture needle and a cuff that applies pressurized air to inflate and apply pressure to the finger, enhancing blood collection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a subject collects blood by themselves without professional assistance, then the procedure is simple and requires no specialist, but the blood collection efficiency is insufficient and cannot collect enough blood
Solution Approach 1:
The system enables self-service blood collection by providing all necessary professional functions (vein identification, puncture control, pressure application) through automated devices that the subject can operate independently, resolving the contradiction between ease of operation and blood collection efficiency
Solution Approach 2:
The patent replaces manual mechanical operations (doctor/nurse performing puncture and pressure application) with automated mechanical systems (puncture needle mechanism, cuff inflator), maintaining high collection efficiency while simplifying operation for the subject
2Device complexity
If manual blood collection by non-specialists is used, then the device complexity is low, but the measurement precision and blood collection accuracy are insufficient
Solution Approach 1:
The automated system performs precise vein identification and puncture positioning functions that would be complex for a non-specialist to master manually, while keeping the overall device simple through automation
Solution Approach 2:
The system introduces an intermediary automated mechanism between the subject and the blood collection process, where the device handles the precise technical operations (vein detection, puncture angle control, pressure regulation) while the subject simply needs to place their finger on the device
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively collects a sufficient amount of blood by improving blood collection efficiency and accuracy, allowing for more precise vein puncture and increased blood volume.
Implementation Method 1
a cuff control unit configured to supply pressurized air to the cuff so as to inflate the cuff and apply a predetermined pressure to the finger of the subject

AI summary
In order to solve such a problem, the invention provides a blood collection system used for collecting blood of a subject and a blood collection method executed in the blood collection system. The blood collection system punctures a finger of the subject with a puncture needle; and then supplies pressurized air to a cuff attached to the finger of the subject in a rolling manner so as to inflate the cuff and apply a predetermined pressure to the finger of the subject.
