Summary
A new 3D-printed syringer device speeds up allergic contact dermatitis patch test preparation by dispensing 10 haptens simultaneously. This novel method improves precision and reduces errors in patch testing.
Area of Science:
- Dermatology
- Allergy and Immunology
- Medical Device Technology
Background:
- Traditional patch test preparation for allergic contact dermatitis is time-consuming and prone to errors.
- Accurate allergen dispensing is crucial for reliable diagnostic results.
Purpose of the Study:
- To introduce and evaluate a novel syringer device for simultaneous dispensing of 10 petroleum-based haptens.
- To assess the device's impact on preparation time and dispensing accuracy.
Main Methods:
- A custom syringer was designed and fabricated using 3D printing with polylactic acid.
- The syringer was used to dispense 10 unique haptens simultaneously for patch testing.
Main Results:
- The syringer significantly reduced preparation time, averaging 6.9 seconds compared to 29.6 seconds for the traditional method (P < 0.05).
- The device demonstrated significantly lower average deviation in mass dispensed per well compared to the traditional method (P < 0.05).
Conclusions:
- The 3D-printed syringer is an effective tool for rapidly preparing patient-ready patch tests.
- This device enhances precision and efficiency in the diagnostic process for allergic contact dermatitis.
