Assistance Device With Puncture And Blood Sampling Guides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Diabetic patients with disabled hands or limited dexterity face challenges in handling puncture devices and blood glucose meters, particularly when performing skin puncture and measurement tasks, which can be stressful and difficult due to trembling hands or visual impairments.
Innovation Solution
An assistance device with a main body and lid that includes a puncture guide for aligning the puncture needle and a blood sampling guide for aligning the measurement tool, along with a bleeding accelerator and fixing means, allowing for secure and easy skin puncture and measurement, even for users with weak vision or trembling hands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a diabetic patient manually handles the puncture device and measurement tool, then the patient can perform blood glucose measurement, but patients with disabled hands or trembling hands find it difficult to handle and perform reliably
Solution Approach 1:
The patent introduces an intermediary device (the holder with positioning structures) that mediates between the user and the puncture device/measurement tool. The holder provides positioning guides that align the puncture needle and measurement tool with the fingertip, reducing the skill and stability required for manual operation. This intermediary structure enables patients with disabled hands or trembling hands to perform reliable puncture and measurement operations without requiring high manual dexterity.
Solution Approach 2:
The holder is designed to be self-positioning on the fingertip, with features that automatically align the device components with the blood sampling site. The positioning guides and alignment structures enable the device to self-correct for user instability, allowing patients with limited manual control capability to achieve reliable positioning and operation without requiring advanced manual skills.
2Manufacturing precision
If the puncture device and measurement tool are used without positioning guides, then the device structure remains simple, but accurate alignment with the skin puncture position and blood sampling region cannot be achieved
Solution Approach 1:
The holder incorporates positioning guides and alignment structures only at the specific locations where precision is needed (at the fingertip interface), while the rest of the device remains simple. The positioning guides are localized features on the holder that provide accurate alignment for the puncture needle and measurement tool without requiring the entire device to be complex. This localized approach achieves high alignment precision with minimal added complexity.
3Ease of operation
If the assistance device includes positioning guides and alignment structures, then puncture and measurement operations become reliable and easy even for patients with disabilities, but the device structure becomes more complex
Solution Approach 1:
The patent merges multiple functions into a single integrated holder structure. The holder combines the functions of positioning the puncture device, guiding the measurement tool, and stabilizing the fingertip interface, all within one component. By combining these positioning and alignment functions into a single holder rather than separate components, the device achieves ease of operation for patients with disabilities while minimizing the overall structural complexity.
