Abstract

The invention relates to a dermatological external medicine smearing device, comprising a horizontally arranged piston cylinder, a piston, a piston push rod and a smearing head arranged on the right side of the piston, the left end of the piston cylinder is provided with a horizontally arranged extrusion hole, and the piston There is a vertical chute with an upward opening on the cylinder. The vertical chute and the extrusion hole intersect each other and pass through each other. In the vertical chute, there is a baffle that can slide vertically and a spring placed under the baffle. Under the action of the elastic force, it slides upward and completely closes the extrusion hole; the smear head has a horizontally arranged medicine outlet and a vertically arranged vertical plate placed on the right side of the medicine outlet, and the vertical plate is provided with the medicine outlet. The holes are coaxial and correspond to the through holes; the present invention is easy to operate, which can not only prevent the infection or cross infection of pathogens, but also prevent the medicine from being accidentally squeezed out or swallowed.

Description

technical field [0001] The invention relates to the technical field of dermatology medical tools, in particular to a dermatology external medicine applicator.
