Description
Technical Field
[0001] The utility model relates to the field of medical instruments, in particular to a novel gynecological medicine pusher. Background Art
[0002] Gynecology is a diagnostic and treatment subject in medical institutions, which is divided into Western medicine gynecology and traditional Chinese medicine gynecology. Gynecology is a branch of obstetrics and gynecology, and is a professional department that mainly treats female gynecological diseases. The gynecological diseases it treats include vulvar diseases, vaginal diseases, uterine diseases, fallopian tube diseases, and ovarian diseases. In gynecological clinical practice, vaginal medication is the most commonly used and effective means of treating vaginal inflammation. It uses a drug delivery device to deliver topical medications directly to the lesion site to achieve the purpose of treatment.
[0003] At present, the drug delivery device for gynecological external medicines such as liquid medicine, gel and paste is generally composed of a drug delivery tube, a piston and a push rod. The piston squeezes the liquid medicine so that the liquid medicine is sprayed to the inner wall of the vagina through the hole opened on the drug delivery tube. However, since the vagina has a certain contraction function, when the drug delivery tube is pushed into the vagina, the vagina will adapt to the size of the drug pusher, and then the inner wall of the vagina will wrap around the drug delivery tube, thereby blocking the hole opened on the drug delivery tube, making it difficult for the liquid medicine to be sprayed out, causing certain difficulties in applying the medicine, and reducing the effect of applying the medicine. Utility Model Content
[0004] The main purpose of the utility model is to overcome the shortcomings of the prior art and provide a new gynecological medicine pusher which can open the vagina through the opening plate on the medicine spraying barrel so that the vagina will not block the medicine spraying hole, thereby ensuring the medicine application effect.
[0005] The utility model adopts the following technical solutions:
[0006] A novel gynecological medicine pusher comprises a medicine storage cartridge, a medicine delivery cartridge, a medicine pushing mechanism and a medicine applying mechanism, wherein the medicine delivery cartridge is arranged at the front end of the medicine storage cartridge, a medicine storage cavity is provided in the medicine storage cartridge, a medicine delivery cavity is provided in the medicine delivery cartridge, the medicine storage cavity and the medicine delivery cavity are communicated with each other, a medicine delivery hole is provided on the wall of the medicine delivery cartridge, the medicine delivery hole is communicated with the medicine delivery cavity, the medicine pushing mechanism is arranged at one side of the medicine storage cartridge and can slide in the medicine storage cavity and the medicine delivery cavity, the medicine applying mechanism comprises a medicine spraying cartridge, the medicine spraying cartridge is sleeved on the outside of the medicine delivery cartridge, the medicine spraying cartridge comprises a support plate and a medicine spraying portion, the support plate and the medicine spraying portion are arranged one by one along the circumferential direction of the medicine spraying cartridge, the medicine spraying portion is communicated with the medicine delivery hole, and the support plate protrudes from the medicine spraying portion.
[0007] Furthermore, the medicine applying mechanism also includes a fixing ring, and the medicine spray barrel can be rotatably set between an open state and a closed state through the fixing ring. When the medicine spray barrel is in the open state, the medicine spray part is connected to the medicine dosing hole, and when the medicine spray barrel is in the closed state, the medicine spray part and the medicine dosing hole are staggered with each other.
[0008] Furthermore, the spraying part is provided with a plurality of spraying holes which penetrate the side wall of the spraying barrel in a radial direction, and the spraying holes correspond to the drug delivery holes one by one.
[0009] Furthermore, the medicine applying mechanism also includes a propulsion head, which is arranged on the top of the medicine spraying barrel and has a hemispherical structure.
[0010] Furthermore, it also includes a protection plate, which is arranged at the connection between the drug storage cylinder and the drug delivery cylinder, and the protection plate is an elliptical structure.
[0011] Furthermore, the edge of the protection plate protrudes toward one side of the drug delivery barrel, so that a receiving cavity is formed on the side of the protection plate facing the drug delivery barrel, and drug absorbent cotton is arranged in the receiving cavity.
[0012] Furthermore, the medicine pushing mechanism includes a medicine pushing plate, a medicine pushing rod and a medicine pushing piston, the medicine pushing rod is arranged between the medicine pushing plate and the medicine pushing piston, the medicine pushing piston is arranged in the medicine storage cavity and the medicine pushing piston can slide in the medicine storage cavity and the drug delivery cavity.

[0015] Furthermore, scale lines are arranged on the transparent cover.
[0016] From the above description of the utility model, it can be seen that compared with the prior art, the beneficial effects of the utility model are:
[0017] First, the medicine is pushed from the medicine storage cavity into the medicine administration cavity through the medicine pushing mechanism, and then sprayed into the lesion through the medicine administration hole and the medicine spray hole in sequence. By setting a spreading plate, the spreading plate is brought into contact with the inner wall of the vagina to spread the inner wall of the vagina, thereby preventing the inner wall of the vagina from being tightly attached to the medicine spray barrel and causing the medicine spray hole to be blocked, thereby ensuring the efficiency and effect of medicine application.
[0018] Second, the medicine spray hole can be rotated between an open state and a closed state through a fixed ring. When the medicine liquid inside the medicine storage cylinder needs to be dosed multiple times, the medicine spray cylinder can be rotated after each dosing to make the medicine spray hole and the dosing hole misaligned, thereby reducing the occurrence of accidental contact during storage that causes the medicine liquid to spray out.
[0019] Third, during the spraying process, the protective plate will be attached to the vaginal opening. When the liquid medicine is sprayed into the vagina, part of the liquid medicine that flows out will be absorbed by the absorbent cotton set on the protective plate, which can prevent the liquid medicine from staining the sheets or clothes and reduce the burden on the user after use.
[0020] Fourth, the consumption of the medicine liquid inside the medicine storage cartridge can be observed through the transparent cover and the scale lines, and the amount of medicine liquid used can be controlled according to the actual situation. BRIEF DESCRIPTION OF THE DRAWINGS
