The utility model provides a vagina medicine feeder, which is used for injecting medicine into vagina.

Referring to fig. 1, 2 and 3, the present invention provides a vaginal drug delivery device, which comprises a push rod 11 and a tube 12. The body 12 has the confession the push rod 11 stretches into first port 12a, and with the relative second port 12b of first port 12a end, the protruding sealed butt portion 121 of annular that is equipped with of inner wall of body 12, the sealed butt portion 121 of annular with be formed with the accommodation space 122 that supplies the first adaptation of extrusion of pencil between the second port 12b, work as the extrusion head of pencil stretches into during accommodation space 122, the sealed butt portion of annular with the sealed butt of terminal surface of extruding the head.

The medicine tube is usually an aluminum tube, an extrusion head of the medicine tube is provided with external threads, and after the medicine tube is matched with the vagina medicine feeder, the medicine enters the medicine tube from the extrusion head through extruding the medicine tube. In this embodiment, since the inner wall of the tube 12 is provided with the annular sealing abutting part 121, after the extrusion head of the drug tube is abutted with the vaginal administration device, the annular sealing abutting part 121 can be abutted with the extrusion head of the drug tube, so that the drug cannot leak from the end face of the extrusion head in the lateral direction.

It should be noted that although the outer wall of the extrusion head is provided with the external thread, the pipe body 12 of the present invention may not be provided with the thread, that is, the sidewall of the accommodating space 122 may not be provided with the internal thread, and of course, an internal thread 122a (refer to fig. 4a and 4b) adapted to the external thread of the outer wall of the extrusion head may also be provided, and the following will continue to describe a specific embodiment in which the sidewall of the accommodating space 122 is provided with the internal thread 122a and is not provided with the internal thread.

The technical scheme of the utility model be provided with annular seal butt portion 121 through the body 12 at the vagina ware of dosing to when the extrusion head of pencil and body 12 butt joint, annular seal butt portion 121 can with extrude the terminal surface seal butt of head, thereby can avoid when the extrusion pencil, medicine side direction seepage.

In the above embodiments, it is mentioned that the outer circumference of the extrusion head is provided with an external thread, so as to facilitate the adaptation of the extrusion head to the tube 12, in a preferred embodiment, the sidewall of the accommodating space 122 is provided with an internal thread 122a for screwing with the extrusion head of the cartridge. So, the user when butt joint pencil and body 12, only need very light dynamics rotatory pencil or body 12 can, when revolve twist to with annular seal butt portion 121 butt, can exert oneself slightly, make extrude head and annular seal butt portion 121 tight-fitting to can be very effectual prevent medicine side direction seepage.

Unlike the above embodiments, referring to fig. 5 to 8, in the present embodiment, the sidewall of the accommodating space 122 is a soft plastic layer 123. That is, the entire tube 12 can be made of flexible plastic (fig. 8); it is also possible that only the sidewall of the accommodating space 122 is the soft plastic layer 123 (fig. 6), and for this way, the tube 12 needs to be formed by two-shot molding. The forming process comprises the following steps: firstly, a hard plastic layer is adopted for injection molding to form the pipe body 12 (the accommodating space 122 of the pipe body 12 is relatively large), then the molded pipe body 12 is transferred into a mold, soft plastic is injected into the mold and fills the original accommodating space 122, after secondary injection molding, the soft plastic layer 123 is filled in the inner wall of the original accommodating space 122, so that the inner wall of the original accommodating space 122 is thickened, and the accommodating space 122 matched with the extrusion head can be formed. Of course, considering that the extrusion head needs to tap the soft plastic layer 123, in order to prevent the soft plastic layer 123 from falling off, a protrusion (not shown) may be disposed on the sidewall of the original accommodating space 122, or a rough surface may be disposed, so as to increase the stability of the soft plastic layer 123 to a great extent.

When the user aligns the extrusion head with the accommodating space 122, the user needs to screw the cartridge or the tube 12 with force, so that the external thread of the extrusion head taps the inner wall of the accommodating space 122, thereby forming an internal thread 122a adapted to the external thread until the end face of the extrusion head is screwed to be tightly abutted to the inner wall of the accommodating space 122.

For the side wall of the accommodating space 122, an elastic material layer may also be used. Such as a rubber layer, a silicone layer, a latex layer, a polyurethane layer or a polycarbonate layer. Because above-mentioned material matter is gentle, easy deformation, so when receiving to extrude the head extrusion, the elastic material layer can be by compression deformation, when revolving the pencil or body 12 soon, the dynamics of attacking the tooth is lower relatively, and sealed effect is also good.

In another preferred embodiment, referring to fig. 4a, 6 and 8, the surface of the annular sealing abutment 121 facing away from the second port 12b is an inwardly inclined annular surface 121a, so that when the user squeezes the extrusion head, the annular surface 121a guides the drug to reduce the lateral squeezing force generated by squeezing the drug, thereby further preventing lateral leakage of the drug, the inclined angle α of the annular surface 121a is not too large or too small, the angle α is too large, the drug permeability between the annular sealing abutment 121 and the extrusion head is increased, the angle is too small, the guiding effect on the drug is poor, and the drug permeability between the annular abutment and the extrusion head is also increased, in view of this, the angle α is optimal around 45 °, so that the drug permeability can be balanced, in this embodiment, the inclined angle α of the annular surface 121a is 40 ° to 50 °, such as α °, 44 °, 46 °, 48 °.

Referring to fig. 4b, the surface of the annular sealing abutment 121 facing away from the first port 12a extends obliquely toward the second port 12b in a direction from the periphery thereof toward the axis of the pipe body 12. Thus, when the user abuts the extrusion head of the cartridge with the dispenser 10, the cartridge can be rotated by force, the extrusion head of the cartridge exerts an abutting force on the annular sealing abutting portion 121, and the annular sealing abutting portion 121 deforms after being stressed, so that the annular sealing abutting portion 121 tends to be flat.

The surface of the annular sealing abutment 121 facing away from the first port 12a has an angle β with respect to a plane perpendicular to the axis of the tubular body 12. here, the size of β can be determined by the material of the annular sealing abutment 121, and if the annular sealing abutment 121 is relatively stiff, β is not likely to be too large, for example, β can be 1 ° to 40 ° (1 °, 3 °, 5 °, 8 °, 10 °, 15 °, 18 °, 20 °, 22 °, 25 °, 27 °, 30 °, 32 °, 35 °, 38 °, 40 °), and if the material of the annular sealing abutment 121 is relatively soft, the arrangement of β can be slightly larger, and β can be at 2 ° to 20 ° (2 °, 4 °, 6 °, 7 °, 9 °, 12 °, 16 °, 18 °, 20 °).

In another embodiment, referring to fig. 3, 5 and 7, the minimum inner diameter of the accommodating space 122 is r₁(in the case of a thread, the minimum internal diameter r is the internal diameter defined by the thread closure₁At a position close to the annular sealing abutting portion), the minimum inner diameter of the annular sealing abutting portion 121 facing away from the accommodating space 122 is r corresponding to the minimum inner diameter of the pipe body 12₂，r₁＜r₂. So, when extrudeing the pencil, can effectively reduce because of the extrusion medicine, and the side direction extrusion force that produces.

Referring to fig. 3, 5 and 7, it is mainly considered that when the tube 12 is pushed into the vagina, the inner vaginal membrane of the user is easily scratched due to the sharp corner of the front end of the tube 12. In view of this, in the present embodiment, the diameter of the end of the outer wall of the pipe body 12 close to the second port 12b is gradually reduced in a direction away from the first port 12 a.

Thus, the tube 12 itself has a guiding function when the tube 12 guides the injection of the medicine. In addition, because the diameter of the middle part of the tube body 12 is larger than that of the front end, when the tube body 12 is inserted into a vagina, the middle part of the tube body 12 has a certain expansion effect on the vagina, and the scraping force of the front end of the vagina at the expanded position by the corner of the front end of the tube body 12 is relatively small, so that the vagina is not easy to be injured.

Referring to fig. 3, 5 and 7, in order to facilitate the user to hold the tube 12 with his or her fingers, in this embodiment, the diameter of the end of the outer wall of the tube 12 close to the first port 12a gradually increases in a direction away from the second port 12 b.

In addition, when injecting the medicine, on one hand, to facilitate the user to hold the medicine, and on the other hand, to prevent the tube 12 from sliding into the vagina entirely, in a preferred embodiment, the first port 12a is further protruded with a side ear 124 at the periphery. The user can hold the side ear 124 for injection, and the side ear 124 can effectively prevent the tube body 12 from slipping into the vagina.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
