[0026] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the gynecological medication applicator proposed in this invention. The advantages and features of this invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention.

[0027] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the state, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0029] like Figures 1-6 As shown, a gynecological medication applicator includes a medication cartridge 1 and a plunger 2 disposed within the medication cartridge 1. The front end of the medication cartridge 1 is provided with an extension 3, an expansion section 4, and a limiting ring 5. The medication cartridge 1 also has an operating part 6 for horizontally moving the limiting ring 5. The extension 3 includes a receiving body 31 and a hemisphere 32. The hemisphere 32 is connected to the medication cartridge 1 via the receiving body 31. The diameter of the hemisphere 32 is smaller than the diameter of the medication cartridge 1, so that when the expansion section 4 supports the vaginal wall, the hemisphere 32 is no longer supported on the vaginal wall, thereby preventing the hemisphere 32 from pushing secretions deeper into the vagina. The receiving body 31 has a cylindrical structure. The expansion section 4 includes an elastic support ring 41 and an absorbent layer 42. The elastic support ring 41 is larger on the left and smaller on the right. The structure is funnel-shaped, with an elastic support ring 41 fitted around the outer periphery of the receiving body 31 and connected to the front end of the cartridge 1. An absorbent layer 42 is provided on the inner wall of the elastic support ring 41. The elastic support ring 41 expands and supports itself against the vaginal wall when not under force, and retracts after being squeezed by the limiting ring 5, so that the diameter of the funnel opening of the elastic support ring 41 is smaller than the diameter of the hemisphere 32. The limiting ring 5 is fitted around the outer side of the elastic support ring 41. When the limiting ring 5 moves to the left, it compresses the elastic support ring 41, causing the elastic support ring 41 to retract. When the limiting ring 5 moves to the right, it releases the limitation on the elastic support ring 41, and the left end of the elastic support ring 41 expands and supports itself against the vaginal wall. To facilitate insertion, the upper side of the limiting ring 5 is designed with an arc transition.

[0030] In the initial state, the limiting ring 5 is close to the hemisphere 32, and the elastic support ring 41 is retracted under the limiting action of the limiting ring 5, and the gynecological medicine pusher is in a state convenient for insertion into the vagina. The hemisphere 32, the limiting ring 5, and the medicine cartridge 1 are sequentially inserted into the vagina. When the front end of the medicine cartridge 1 is inserted into the vagina, the control operation part 6 is operated to move the limiting ring 5 to the right, release the elastic support ring 41, and support the elastic support ring 41 on the vaginal wall. The vaginal wall secretions are scraped off, and the scraped secretions are absorbed by the liquid absorption layer 42. The vaginal secretions can be greatly reduced and pushed into the deep part of the vagina. Specifically, the liquid absorption layer 42 is made of sponge, water-absorbing resin, water-absorbing gel, and other materials that can absorb water and deform.

[0031] The gynecological medicine pusher has two medicine delivery forms, including front-end delivery and side delivery. In some embodiments, as shown in Figure 7 , the gynecological medicine pusher is front-end delivery, and the front end of the medicine cartridge 1 is provided with a push channel 101, which penetrates the receiving body 31 and the hemisphere 32. During use, the medicine in the medicine cartridge 1 is pushed into the vagina through the push channel 101 by pushing the medicine plunger 2; in other embodiments, as shown in Figures 1-5 , the gynecological medicine pusher is side delivery, and the side of the medicine cartridge 1 is provided with a plurality of side holes 102. During use, the medicine in the medicine cartridge 1 is squeezed onto the vaginal wall through the side holes 102 to complete the medicine application by pushing the medicine plunger 2. Further, since the vaginal wall has folds, the medicine cartridge 1 includes a medicine delivery section 11 and a non-medicine delivery section 12. The plurality of side holes 102 are arranged on the medicine delivery section 11, and the medicine delivery section 11 is located at the front end of the medicine cartridge 1. An outer cylinder 13 is arranged on the non-medicine delivery section 12, and a limiting channel for the movement of the operation part 6 is arranged between the outer cylinder 13 and the non-medicine delivery section 12. The outer cylinder 13 is used to support the vaginal wall and cooperate with the expansion part 4 to support the vaginal wall corresponding to the medicine delivery section 11, so that the medicine can be squeezed into the folds of the vaginal wall, thereby improving the medicine delivery effect.

[0032] In some embodiments, the outer ring of the receiving body 31 is provided with an annular groove 311 for placing the liquid-absorbing layer 42, and a plurality of micro-holes 312 are arranged on the annular groove 311. The receiving body 31 and the inner part of the hemispherical body 32 are provided with a cavity 313 in communication. The liquid-absorbing layer 42 is a sponge. When the limiting ring 5 is located on the left side of the elastic supporting ring 41, the sponge is in a compressed state in the annular groove 311. In use, the limiting ring 5 moves to the right, and the elastic supporting ring 41 releases the sponge to absorb the secretion. During the advancement of the cartridge 1, the water absorption capacity of the sponge decreases due to the increase of the absorbed secretion. The limiting ring 5 is pushed to the left by the operation part 6, so that the elastic supporting ring 41 compresses the sponge in the annular groove 311, and the secretion is squeezed into the cavity 313 through the micro-holes 312 for collection. The secretion is difficult to be discharged from the lower micro-holes 312 by gravity alone. The limiting ring 5 is moved to the right again to make the elastic supporting ring 41 enter the working state, thereby ensuring the performance of the sponge in absorbing the secretion.

[0033] In some embodiments, the operation part 6 includes a connecting plate 61 and an operation ring 62. The connecting plate 61 passes through the limiting channel, and the two ends of the connecting plate 61 are connected with the operation ring 62 and the limiting ring 5, respectively. The operation ring 62 is arranged at the rear end of the cartridge 1, and the outer ring of the operation ring 62 is bent to form a disc structure, thereby avoiding the problem that it is difficult to operate manually when the operation ring 62 is close to the cartridge 1.

[0034] In some embodiments, the elastic supporting ring 41 includes a trumpet-shaped medical silica gel ring 411 and a plurality of elastic rods 412. The plurality of elastic rods 412 are arranged on the inner side of the medical silica gel ring 411, and the end portions of the elastic rods 412 are connected to the front end of the cartridge 1. The elastic rods 412 maintain the medical silica gel ring 411 in a raised state in a natural state.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application rather than limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
