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.

Claims

1. An endermic application kit for external medicines, comprising:

a container for retaining liquid containing drug, said container having a bottom opening, an inlet for the liquid, and an outlet for the liquid,

means for supplying the liquid containing drug into the container,

a drug permeable layer attached to the container to cover the bottom opening of the container, and

an ultrasonic oscillator situated inside the container so that when the ultrasonic oscillator and supplying means 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.

2. An endermic application kit according to claim 1, wherein said supplying means continuously supplies the liquid containing drug into the container through the inlet and removes the liquid in which the drug is consumed through the outlet.

3. An endermic application kit according to claim 2, further comprising an external oscillator device connected to the ultrasonic oscillator.

4. An endermic application kit according to claim 3, wherein said inlet is situated at one side of the container, and the outlet is situated at the other side away from the inlet.
