An anti-pollution ointment applicator

Abstract

The invention relates to an anti-contamination ointment applicator, which comprises a horizontal piston barrel, a piston, a piston push rod and an applying head. The piston push rod is arranged on theright side of the piston, the left end of the piston barrel is provided with a horizontal extruding hole, the piston barrel is provided with a stop valve for controlling circulation direction of theextruding hole, and a plurality of connecting rods distributed axially and peripherally along the extruding hole are arranged on the piston barrel. One end, away from the stop valve, of each connecting rod is in rotational connection with the piston barrel through a torsion spring. The other end of each connecting rod is arranged on the right half portion of a rotating circumference of the corresponding connecting rod. The piston barrel is provided with rotating limiting grooves matched with the connecting rods, and when the connecting rods rotate in the limiting grooves, the other end of eachconnecting rod contacts with or separates from a valve element of the stop valve. The left end face of the piston barrel is provided with a plurality of horizontal insertion holes in one-to-one corresponding communication with the rotating limiting grooves, the applying head is provided with a plurality of ejection rods on the right side of the applying head, the ejection rods are matched with the horizontal insertion holes in a one-to-one correspondence manner, and the applying head is provided with an ointment outlet hole corresponding to the extruding hole.

Description

technical field [0001] The invention relates to the technical field of dermatological medical tools, in particular to an anti-pollution ointment 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 th...
