Electric Skin Allergy Test Device With Controlled Pulse Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The prick test for skin allergy diagnosis faces challenges in standardization due to variability in lancet penetration depth and location, leading to diffusion and contamination issues, and can cause patient anxiety and discomfort.
Innovation Solution
An electric medical device that prints ink marks on the skin and emits a controlled electric pulse to create small surface holes, allowing for precise allergen application and observation of reactions, with adjustable pulse intensity and duration, and a brush dispenser to minimize diffusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a lancet is used to scratch the skin in the prick test, then the allergen can penetrate under the skin surface layers, but the penetration depth and location cannot be standardized by different lancets
Solution Approach 1:
The patent replaces the manual mechanical lancet scratching system with an automated electric pulse delivery system. The electric device prints precise locations on the skin and delivers controlled electric pulses through electrodes, eliminating the variability of manual lancet application while maintaining effective allergen penetration.
Solution Approach 2:
The device performs preliminary actions by first printing the exact locations where tests will be conducted, then applying allergens to those marked areas, and finally delivering electric pulses at precisely controlled moments. This sequential preliminary positioning ensures standardization before the actual penetration occurs.
2Quantity of substance
If drops of allergen are applied at one point during the prick test, then the allergen can be delivered to the skin, but diffusion and contamination of adjacent application sites occurs
Solution Approach 1:
The device segments the allergen delivery process by printing distinct separated locations on the skin before applying allergens. Each test area is clearly demarcated and isolated, preventing diffusion and contamination between adjacent application sites while ensuring adequate allergen delivery to each location.
Solution Approach 2:
The printed marks serve as an intermediary guide layer between the allergen application and the skin surface. These marks define precise boundaries and locations, acting as a mediator that ensures allergens are applied to correct areas without spreading to adjacent sites.
3Quantity of substance
If a lancet is used to penetrate the skin in the prick test, then the allergen can be delivered under the skin, but patient anxiety and discomfort increase
Solution Approach 1:
The patent substitutes the painful mechanical lancet penetration with a non-invasive electric pulse delivery system. The electric device uses electrical fields to facilitate allergen penetration through the skin without physical puncture, eliminating pain and bleeding while reducing patient anxiety and belonephobia.
Solution Approach 2:
The invention converts the potentially harmful mechanical puncture into a beneficial electric field application. The electric pulse, which could be harmful at high intensities, is used at controlled levels to achieve gentle, painless allergen delivery while maintaining effective skin penetration.
