AI Technical Summary

Technical Problem

Existing technologies are inaccurate, time-consuming, and inefficient when measuring irregular skin areas, making it difficult to achieve quantitative drug treatment.

Method used

A flexible film with a uniformly distributed grid is used to trace and cut out a film that matches the contour of the skin in the target area. The area of ​​the film is calculated by weighing and scanning, combined with computer analysis software, and the average value is taken to obtain the skin area of ​​the target area.

Benefits of technology

It improves the accuracy and speed of irregular skin area measurement, enabling more precise measurement of irregular skin areas, and is suitable for skin area measurement in patients with postherpetic neuralgia.

Abstract

This invention relates to the field of medical measurement technology, specifically to a method for measuring the area of ​​irregular skin, comprising the following steps: using a flexible film printed with a uniformly distributed grid to trace and cut out a film sheet that matches the contour of the target area of ​​skin; obtaining the film sheet area S1 based on the weight per unit area of ​​the flexible film and the weight of the film sheet; obtaining the film sheet area S2 based on the number of grids per unit area of ​​the flexible film and the number of grids on the film sheet; and averaging S1 and S2 to obtain the skin area of ​​the target area. This invention, by using a flexible film that more easily conforms to irregular skin and by averaging two measurement methods, can significantly improve the calculation accuracy and increase the accuracy of measuring irregular skin area. Compared to existing technologies, it is faster and more accurate, and can effectively measure the area of ​​skin with abnormal pain sensation, such as in patients with postherpetic neuralgia.
