Abstract
Abstract An endermic application kit for external medicines comprises a container for retaining liquid containing drug, a device for supplying the liquid containing drug into the container, a drug permeable layer attached to the container to cover a bottom opening of the container, and an ultrasonic oscillator situated inside the container. When the ultrasonic oscillator and supplying device are actuated, the liquid containing drug is continuously supplied to the container, and the drug contained in the liquid is applied to a skin of a patient through the drug permeable layer by means of the ultrasonic oscillator.
