Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical supplies, in particular to a vaginal drug delivery device. Background Art
[0002] Gynecological diseases often require vaginal medication. Common medication devices are mainly composed of a syringe connected to a medication tube. When giving gynecological medication to a patient, the medication tube is inserted into the vagina and the syringe is pushed to inject the drug.
[0003] Due to differences in human physique, different patients have different body shapes and vaginal depths. For certain obese patients with deep vaginas, due to permeability limitations: the drug permeability of vaginal injection applicators is limited by the vaginal wall. Due to the physiological structure of the vaginal wall and the characteristics of the mucosal layer, some drugs may be difficult to fully penetrate into the target area, thus affecting the treatment effect. Commonly used vaginal applicators (injection applicators, extrusion applicators) are not enough to meet the space required for operation. For thinner patients, those with shallow vaginas, or those who have received certain treatments, it is difficult to inject the drug into the designated location. Even many novices often cause uneven drug injection during injection. The accurate position and easy slip of the syringe out of the vaginal opening make it difficult to fix, which will also hinder treatment. Utility Model Content
