AI Technical Summary

Technical Problem

Existing transdermal drug delivery devices suffer from inaccurate temperature control, which may affect drug activity and absorption. Furthermore, the dressing plate is not fixed in place and is prone to falling off, making it difficult to achieve precise drug delivery.

Method used

Temperature is controlled by a combination of heating and temperature sensing elements, and an image sensor monitors skin condition. The negative pressure outer ring cavity adjusts the adsorption force through an independent negative pressure sub-cavity. The central drug delivery cavity and the negative pressure outer ring cavity are designed to adapt to the skin's contours, and the central convex post is used for drug pad positioning and fixation.

Benefits of technology

It ensures drug activity and absorption, prevents skin burns, and guarantees the stability and accuracy of the drug administration process.

Abstract

The utility model belongs to the technical field of medical instruments, and relates to a transdermal drug delivery device and transdermal drug delivery equipment. The application disc is provided with a central drug delivery cavity and a negative pressure outer ring cavity, the central drug delivery cavity can provide proper drug delivery temperature through heating, and the negative pressure outer ring cavity provides adsorption force to skin through connection with the host device. A temperature sensing element and an image sensor are further arranged on the application disc, so that more accurate temperature control and real-time monitoring of the skin state are achieved, and discomfort possibly occurring in the transdermal drug delivery process is avoided. After drug administration is completed, the main machine device can automatically relieve pressure so that the application disc can be taken down conveniently. According to the application, the safety and effectiveness of transdermal drug delivery are effectively improved.
