Abstract
Description
Technical Field
[0001] This utility model relates to the field of vaginal medication technology, specifically to a vaginal medication device. Background Technology
[0002] For patients with vaginitis, regular application of medication to the inflamed area is necessary. The procedure typically involves first thoroughly rinsing the vagina before applying the medication. Metronidazole is a commonly used medication for vaginitis; it is in powder form and primarily used to treat or prevent systemic or local infections caused by anaerobic bacteria. Currently, when applying metronidazole, the vagina is usually opened with speculum forceps, and then a cotton swab is repeatedly dipped in the medication and inserted into the vagina for application. This procedure is cumbersome and increases patient discomfort. Utility Model Content
[0003] In view of the shortcomings of the existing technology, this utility model proposes a vaginal medication device to solve the above problems.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] This utility model provides a vaginal medication application device, comprising:
[0006] holding handle;
[0007] A slider is slidably mounted on the handle, one end of the slider is provided with an insertion tube, and the distal end of the insertion tube is provided with a dispensing part;
[0008] The medicine chamber is mounted on the slider, and a connecting tube communicating with the insertion tube is installed on the medicine chamber. An elastic diaphragm is provided at the bottom of the medicine chamber.
[0009] The pressing mechanism can repeatedly press the elastic diaphragm so that the drug in the drug chamber can be pushed out of the dispensing part under pressure.
[0010] Furthermore, the pressing mechanism includes a rack and a rotating column. The rack is mounted on the handle and parallel to the sliding direction of the slider. The rotating column is rotatably mounted on one side of the slider. A gear that meshes with the rack is mounted on the rotating column. A cam is also mounted on the rotating column below the elastic tympanic membrane. When the protruding part of the cam rotates toward the elastic tympanic membrane, it will push the elastic tympanic membrane into the medicine container.
[0011] Furthermore, two baffles are spaced apart on the rotating column, and the cam is axially slidably mounted on the rotating column between the two baffles. The cam can move closer to or further away from the area directly below the elastic tympanic membrane.
[0012] Furthermore, a sealing cap is detachably connected to the medicine compartment.
[0013] Furthermore, a retaining ring is installed on the slider.
[0014] Furthermore, an external vaginal baffle is provided at one end of the handle near the insertion tube, and a through hole is provided on the external vaginal baffle for the insertion tube to pass through.
[0015] Furthermore, the dispensing section has multiple dispensing ports circumferentially.
[0016] As can be seen from the above technical solution, this utility model provides a vaginal medication application device:
[0017] After the insertion tube reaches the deepest part of the patient's vagina, it is slowly pulled out while the elastic diaphragm is repeatedly pressed by a pressing mechanism. This creates periodic pressure inside the medication cartridge, causing the powdered medication to be continuously ejected during the tube's movement. This ensures that the medication is fully applied to the patient's vagina in one go during the tube's back-and-forth movement, significantly improving medication efficiency and reducing patient discomfort. This invention is easy to operate, prevents medication from falling off during application, and allows patients to operate it themselves, avoiding embarrassment. Attached Figure Description

[0028] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0031] like Figure 1-4 As shown, this embodiment provides a vaginal medication device, including a handle 1, a slider 2, a medication container 3, and a pressing mechanism 4.
[0032] The handle 1 is elongated for the user to grip. A slider 2 is slidably mounted on the handle 1 along its length. One end of the slider 2 has an insertion tube 21, and the distal end of the insertion tube 21 has a dispensing part 22. Specifically, as shown... Figure 4 As shown, the dispensing section 22 has multiple dispensing ports 221 circumferentially arranged, allowing the medication to be sprayed out in all directions, repeatedly covering the vaginal wall. The insertion tube 21 can be smoothly slid into the patient's vagina by sliding the slider 2. A buckle 23 is installed on the slider 2 for easy pushing and pulling by the user.
[0033] Preferably, the insertion tube 21 can be made of rubber or silicone to give it a certain degree of elasticity, which can reduce the pressure and stimulation on the vaginal wall and allow it to bend appropriately along the vaginal path, thus improving comfort. Furthermore, the distal end of the insertion tube 21 gradually decreases in size to reduce resistance when it is inserted into the vagina, thereby minimizing patient discomfort.
[0034] The medicine chamber 3 contains metronidazole powder. The medicine chamber 3 is mounted on the slider 2. The medicine chamber 3 is equipped with a connecting tube 31 that communicates with the insertion tube 21. An elastic diaphragm 32 is provided at the bottom of the medicine chamber 3. The elastic diaphragm 32 protrudes outward from the medicine chamber 3. The elastic diaphragm 32 can be made of elastic rubber so that it can automatically return to its original position after being pressed. When the elastic diaphragm 32 is pressed, it will generate instantaneous pressure in the medicine chamber 3, so that the metronidazole powder can be sprayed into the insertion tube 21 through the connecting tube 31 and sprayed out from the medicine outlet 22.
[0035] Preferably, a sealing cover 33 is detachably connected to the medicine compartment 3. The sealing cover 33 can be connected to the medicine compartment 3 by means of threaded connection or other means, so as to facilitate the replenishment of medicine.
[0036] The pressing mechanism 4 can repeatedly press the elastic diaphragm 32 so that the medicine in the medicine chamber 3 can be pushed out of the dispensing part 22 under pressure.
[0037] In practical use, the user holds the handle 1, aligning the distal end of the insertion tube 21 with the patient's vaginal opening. The insertion tube 21 is then gently inserted into the vagina until it reaches its deepest point. While slowly pulling the insertion tube 21 out, the user repeatedly presses the elastic diaphragm 32 using the pressing mechanism 4. This creates periodic pressure inside the medication cartridge 3, causing the powdered medication to be continuously ejected during the movement of the insertion tube 21. This ensures that the medication is fully applied to the patient's vagina during the reciprocating motion of the insertion tube 21, significantly improving application efficiency and reducing patient discomfort. This invention is easy to operate, prevents medication from falling during application, and allows the patient to operate it independently, avoiding embarrassment.
[0038] like Figure 2 As shown, in one embodiment, the pressing mechanism 4 includes a rack 41 and a rotating column 42. The rack 41 is mounted on the handle 1 and parallel to the sliding direction of the slider 2. The rotating column 42 is rotatably mounted on one side of the slider 2. A gear 43 that meshes with the rack 41 is mounted on the rotating column 42. A cam 44 is also mounted on the rotating column 42 below the elastic diaphragm 32. During the process of pulling the slider 2 to pull the insertion tube 21 out of the patient's vagina, the rotating column 42 rotates through the meshing of the gear 43 and the rack 41, thereby causing the cam 44 to rotate. When the protruding part of the cam 44 rotates towards the elastic diaphragm 32, it pushes the elastic diaphragm 32 into the medicine container 3. This allows the cam 44 to continuously rotate and push the elastic diaphragm 32 as the slider 2 moves, so that the powdered medicine can be continuously sprayed out from the medicine outlet 22 as the insertion tube 21 moves. The operation of applying medicine and pulling out the insertion tube 21 is performed simultaneously, simplifying the operation and further improving the efficiency of medicine application.
[0039] Preferably, two baffles 45 are spaced apart on the rotating column 42, and the cam 44 is axially slidably mounted on the rotating column 42 between the two baffles 45. The cam 44 can move closer to or further away from the underside of the elastic tympanic membrane 32. When the cam 44 abuts against one of the baffles 45, it will be located directly below the elastic tympanic membrane 32, and when the cam 44 abuts against the other baffle 45, it will be moved away from the underside of the elastic tympanic membrane 32. This allows the linkage between the cam 44 and the elastic tympanic membrane 32 to be cut off before the insertion tube 21 is inserted into the vagina, preventing the drug from being sprayed out from the dispensing part 22 at the wrong time.
[0040] Preferably, a vulvar baffle 11 is provided at one end of the handle 1 near the insertion tube 21. The vulvar baffle 11 has a through hole for the insertion tube 21 to pass through. When in use, the vulvar baffle 11 can be aligned with the vaginal opening of the patient to prevent the patient's vulva from being injured.
[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
