Problems solved by technology

[0003] Gynecological diseases are basically treated with ointments or gels. The existing drug delivery devices are either gel drug delivery devices used inside the vagina, and the gel drug delivery devices are basically disposable. It is easy to cause waste of materials, or the external ointment drug delivery device is also suitable for one-time use, and repeated use is likely to cause cross-infection. At present, there are basically no gynecological drug delivery devices that exist at the same time for internal use and external use.

Abstract

The invention discloses an ointment application apparatus, comprising a mounting barrel. A piston rod is nested movably to the inner wall of the mounting barrel; the upper surface of the piston rod is provided with a press hole; a piston sheet is connected fixedly to the lower surface of the piston rod; the inner surface of the mounting barrel is provided with a spiral groove; the lower surface of the mounting barrel is provided with a mounting groove; the surface of the lower end of the spiral groove and the upper surface of the mounting groove are collinear. The ointment application apparatus allows an external tube to be reused; in use, the external tube is mounted in the mounting groove by a user, the surface of the external tube is sleeved with a silicone sleeve, the silicone sleeve is fixed through an elastic fastening ring and is recessed inward, an ointment is extruded to the recess, the piston rod is pressed to eject the ointment which is applied to the affected part, and the silicone sleeve can be removed and discarded. Therefore, the ointment application apparatus has the advantages of low material consumption and reusability.

Description

technical field [0001] The present invention relates to the technical field of medical equipment, more specifically, it relates to a kind of ointment dispensing device. Background technique [0002] At present, in gynecological clinics, vaginal medication is the most commonly used and effective means to treat vaginal inflammation, which is to use the drug delivery device to directly deliver the drug to the lesion to achieve the purpose of treatment; [0003] Gynecological diseases are basically treated with ointments or gels. The existing drug delivery devices are either gel drug delivery devices used inside the vagina, and the gel drug delivery devices are basically disposable. It is easy to cause material waste, or the external ointment delivery device is also only suitable for one-time use, and repeated use may easily cause cross-infection. At present, there is basically no gynecological drug delivery device for internal use and external use at the same time. Contents o...
