An anti-pollution skin applicator

Abstract

The invention relates to an anti-pollution skin drug applicator, which comprises a horizontally arranged piston barrel, a piston, a piston push rod placed on the right side of the piston, and an applicator head. The left end of the piston barrel has a horizontally arranged extrusion hole, and the piston barrel has a The stop valve that controls the flow direction of the extrusion hole. There are multiple radially arranged stop rods distributed on the piston barrel. The rotation limit groove matched with the stop rod, when the stop rod rotates in the limit groove, the other end of the stop rod contacts or separates from the spool of the shut-off valve; there are multiple levels on the right side of the smear head The ejector rod, the horizontal ejector rod and the retaining rod are coaxially corresponding, the horizontal ejector rod has a cam groove set in a spiral, the retaining rod has a through hole coaxially matched with the horizontal ejector rod, and the retaining rod is placed in the through hole The cam push rod; there is a drug outlet hole corresponding to the extrusion hole on the applicator head.

Description

technical field [0001] The invention relates to the technical field of dermatological medical tools, in particular to an anti-pollution skin drug applicator. Background technique [0002] In the process of skin disease treatment, external drug therapy can directly apply the drug to the patient's lesion, so its therapeutic effect is very significant, and it is the main means of skin disease treatment; or liquid, it needs to be squeezed out from the package for smearing during use. Therefore, during the smearing process, when the drug outlet comes into contact with the operator's fingers or directly with the patient's lesion, the drug and the drug outlet of the drug package will Due to secondary pollution, it is very easy to cause cross-infection with other patients when it is used again later, which is not conducive to the treatment and complete recovery of the disease. [0003] At the same time, since the dosage of this type of medicine depends on the condition, generally t...
