Description

Skin adhesive applicator

Technical Field

The utility model belongs to the technical field of external application medicine applicators, and particularly relates to a skin adhesive applicator.

Background

At present, the clinically used skin adhesive is mostly filled and sealed by a glass ampoule bottle to improve the performance stability of the product and prolong the shelf life of the medical adhesive product to the maximum extent, so the glass sealing of the product is a main primary packaging form. The clinical traditional use mode is that a glass ampoule bottle is matched with a pasteur pipette for combined use, the ampoule bottle is directly broken off in the use process, and the pasteur pipette is used for sucking the skin adhesive to be smeared at a wound, so that the mode is inconvenient to operate, long in use time and difficult to control the smearing uniformity, and meanwhile, the broken glass ampoule bottle can fall in the skin adhesive, so that certain potential safety hazards exist; emerging packing is put glass ampoule in silica gel or soft plastics paint the bottle, presses during the use and kneads the ampoule and make ampoule breakage, and liquid flows, but this kind of mode is higher to the dynamics requirement of operator's hand, and difficult broken ampoule in the general doctor nurse use, and has broken ampoule to puncture the shell, punctures the risk of finger.

SUMMERY OF THE UTILITY MODEL
