Description

Technical Field

[0001] The utility model relates to the technical field of medical mechanical devices. Background Art

[0002] Diseases of the female reproductive system are called gynecological diseases. Gynecological diseases include vulvar diseases, vaginal diseases, uterine diseases, fallopian tube diseases, ovarian diseases, etc. Gynecological diseases are common diseases among women and can be treated with external treatments. Many people lack proper knowledge of gynecological diseases and lack of health care. In addition, various bad living habits have caused their physical health to deteriorate, leading to some women suffering from diseases that cannot be cured for a long time, causing great inconvenience to their normal life and work. Especially when vaginal lesions occur, a flushing applicator is needed to allow the liquid medicine to act directly on the vaginal lesions.

[0003] Existing flushing applicators generally insert a needle into the vagina for cleaning, and generally a hose is inserted into the needle to allow the needle to extend further, so that the drug solution can penetrate deeper into the vagina and radiate deeper. However, the outlet end of the general hose is easily blocked by the inner wall of the vagina, making it difficult for the drug solution to be ejected from the hose. At the same time, the hose is not easy to insert deep into the vagina and is easily squeezed by the vagina, so the hose is easy to bend, thus making it difficult for the drug solution to be ejected from the hose. Utility Model Content

[0004] The utility model aims to provide a vaginal flushing medication device to overcome the defect that the medicine liquid is difficult to be sprayed out from the hose due to the resistance of the vaginal inner wall to the hose.

[0005] The technical solution to achieve the above-mentioned purpose is: a vaginal irrigation applicator, comprising a needle tube, the inner wall of the needle tube is slidably connected to a push handle, the bottom end of the needle tube is provided with a needle, the bottom end of the outer wall of the needle tube is threadedly connected to a top ring, the bottom end of the top ring is fixedly connected to four array-distributed outward expansion rods, the bottom end of the outward expansion rods is fixedly connected to a chassis, the top end of the chassis is fixedly connected to an annular nozzle, the liquid inlet end of the annular nozzle is fixedly connected to one end of a hose, the other end of the hose is fixedly connected and communicated with a fixing ring, the upper end of the fixing ring is fixedly connected to two limiting rubber blocks, and the bottom end of the needle tube is fixedly connected to a limiting member.

[0006] Preferably, the limiting member includes a slide groove, a limiting groove and a hard tube, the bottom end of the needle is fixedly connected to the hard tube, the inner side of the hard tube is connected to the needle, the outer wall of the hard tube is provided with two symmetrically distributed slide grooves, the outer wall of the hard tube is provided with two symmetrically distributed limiting grooves, and the inner wall of the fixing ring is slidably connected to the slide groove.

[0007] Preferably, a plurality of through holes are formed at the upper end of the chassis.

[0008] Preferably, a buffer block is fixedly connected to the bottom end of the chassis.

[0009] Preferably, the buffer block is hemispherical in shape.

[0010] Preferably, the outward expansion rod is in the shape of an arc.

[0011] Preferably, the outer wall of the outward expansion rod is provided with rounded corners, and the outer wall of the outward expansion rod is sleeved with a rubber sleeve.

[0012] Preferably, the diameter of the annular nozzle is larger than the diameter of the hose.

[0013] The beneficial effects of the utility model are as follows: the outer expansion rod is extended into the vagina, and the hemispherical shape of the buffer block can be used to gradually increase and expand the opening of the vagina, so that the patient's discomfort is reduced; the outer expansion rod will extend into the vagina through the chassis with the annular nozzle, and the vagina will be expanded by the outer expansion rod to avoid the inner wall of the vagina from blocking the annular nozzle; because the hose is located on the inner side of the outer expansion rod and is straightened, the hose is prevented from bending and affecting the flow of the drug solution in the hose; the push handle is pushed to make the drug solution flow from the needle into the hard tube, and then into the hose, and then sprayed out from the annular nozzle to flush and spray the vagina, thereby increasing the spraying area and improving the drug absorption efficiency.
