[0046] Refer to the following Figure 1-Figure 12 To describe a gynecological care applicator provided by the present invention.

[0047] A gynecological care applicator is suitable for gynecological disease care, including a drug delivery tube 100, the interior of the drug delivery tube 100 can be filled with liquid medicine, a plurality of drug delivery holes 110 are opened on the side wall of the drug delivery tube 100, one end of the drug delivery tube 100 is sealed, and a piston rod 200 capable of axial movement is inserted into the other end of the drug delivery tube 100, the piston rod 200 can increase the pressure inside the drug delivery tube 100, and the liquid medicine in the drug delivery tube 100 is sprayed out from the plurality of drug delivery holes 110. The end of the dosing tube 100 inserted into the piston column 200 is rotatably connected to a holding handle 150, and the operator can limit the axial movement of the dosing tube 100 by using the holding handle 150. At the same time, the piston column 200 is spirally connected to the holding handle 150. The operator pushes the piston column 200 to squeeze out the liquid medicine inside the dosing tube 100 (with the same principle as a syringe). The piston column 200 can drive the dosing tube 100 to rotate around its own axis. A support frame 300 is connected to the holding handle 150, and the support frame 300 surrounds the outer circumference of the dosing tube 100. When the gynecological care dosing device is inserted into the vagina, the support frame 300 can support the inner wall of the vagina, thereby preventing the inner wall of the vagina from blocking several dosing holes 110 of the dosing tube 100. At the same time, the support frame 300 can open the folds of the inner wall of the vagina to avoid dead corners for spraying the liquid medicine.

[0048] A pushing ring 140 is arranged between the outer periphery of the dosing tube 100 and the inner periphery of the support frame 300. The outer periphery of the pushing ring 140 has continuous wavy protrusions 141, and grooves 142 are formed between two adjacent protrusions 141. The pushing ring 140 is specifically fixed on the outer periphery of the dosing tube 100. The dosing tube 100 can drive the pushing ring 140 to rotate around its own axis. The pushing ring 140 rotates relative to the support frame 300. The protrusions 141 and the grooves 142 on the outer periphery of the pushing ring 140 continuously change the supporting position of the support frame 300 supporting the inner wall of the vagina, so that the inner wall of the vagina can be evenly contacted with the medicine solution, thereby playing a good nursing role.

[0049] For example, when the dosing tube 100 is inserted into the inner wall of the vagina, the support frame 300 outside the dosing tube 100 props up the inner wall of the vagina, and the operator pushes the piston column 200, the piston column 200 drives the dosing tube 100, and the dosing tube 100 drives the pushing ring 140, and the pushing ring 140 rotates relative to the support frame 300. Since the pushing ring 140 is provided with a protrusion 141 and a groove 142, the supporting position of the support frame 300 and the inner wall of the vagina is constantly changing, so that the supporting position before the change can also be evenly in contact with the medicine after the change.

[0050] It should be noted that if the supporting position of the support frame 300 remains unchanged, the supporting position is in close contact with the support frame 300, resulting in the inability of the drug liquid to contact this position, thereby causing the problem of uneven contact between the inner wall of the vagina and the drug liquid. Continuously changing the supporting position can allow the original supporting position to contact the drug liquid, so that the drug liquid can contact the inner wall of the vagina more evenly, ensuring the care effect of the drug liquid.

[0051] Specifically, the support frame 300 in this embodiment includes an even number of support rods 310, which are surrounded by the outer circumference of the drug delivery tube 100, and the axis of each support rod 310 is parallel to the axis of the drug delivery tube 100. There is a gap between two adjacent support rods 310 and an elastic plate 320 is connected. The elastic plate 320 elastically connects the even number of support rods 310 together. The even number of support rods 310 have two states when supporting the inner wall of the vagina, namely, a first state and a second state, and the rotation of the push ring 140 can push the even number of support rods 310 to reciprocate along the radial direction of the drug delivery tube 100 to continuously switch between the first state and the second state, thereby continuously changing the support positions of multiple support rods 310.

[0052] In this embodiment, the number of support rods 310 is twelve. When in the first state, Fig.11As shown, two adjacent support rods 310 form a group, and each group of support rods 310 is respectively located in the groove 142 of the push ring 140. The push ring 140 in this embodiment has six grooves 142, and each support rod 310 is respectively located on both sides of the protrusion 141, and there are two support rods 310 in one groove 142. When the support rods 310 prop up the inner wall of the vagina, the twelve support rods 310 are in contact with the inner wall of the vagina. Under the action of the elastic plate 320, the twelve support rods 310 form a shape similar to a regular dodecagon, so as to better prop up the inner wall of the vagina, and the liquid medicine can contact the inner wall of the vagina through the intervals between adjacent support rods 310; when in the second state, such as Fig.12 As shown, one support rod 310 in each group of support rods 310 is located on the protrusion 141, while the other support rod 310 is located in the middle position of the groove 142. This is the case for each group of support rods 310. The support rod 310 located on the protrusion 141 contacts the inner wall of the vagina and supports the inner wall of the vagina, while the support rod 310 located in the groove 142 does not contact the inner wall of the vagina and cannot support the inner wall of the vagina. At this time, the twelve support rods 310 form a shape similar to a regular hexagon under the elastic force of the elastic plate 320. From the original regular dodecagon to the regular hexagon, the number of support points and the support position of the support rod 310 on the inner wall of the vagina change, so that the liquid medicine can be evenly sprayed onto the inner wall of the vagina.

[0053] At the same time, since the rotation of the dosing tube 100 drives the rotation of the push ring 140, the several dosing holes 110 on the dosing tube 100 also rotate with the dosing tube 100. The dosing tube 100 rotates continuously when spraying the liquid medicine, thereby further improving the uniformity of the liquid medicine spraying.

[0054] More specifically, the switching between the first state and the second state is achieved through the following structure, and the specific structure is as follows:

[0055] A limiting ring 160 is fixedly disposed on the gripping handle 150. Figure 8 and Fig.10 As shown, the limiting ring 160 is sleeved on the outer circumference of the drug delivery tube 100, and the limiting ring 160 is provided with first radial grooves 161 evenly distributed in the circumferential direction. A limiting plate 170 is coaxially and rotatably provided on one end of the drug delivery tube 100 away from the gripping handle 150, as shown in FIG. Figure 7 As shown, the limiting plate 170 is provided with a second radial groove 171 evenly distributed in the circumference, the first radial groove 161 and the second radial groove 171 are the same in number and their positions correspond one to one, and the two ends of the support rod 310 are respectively slidably arranged in the first radial groove 161 and the second radial groove 171, so that an even number of support rods 310 can move radially along the dosing tube 100 under the action of the elastic plate 320 and the pushing ring 140, thereby continuously switching the first state and the second state of the even number of support rods 310.

[0056] It should be noted that, in order to facilitate the rotational connection of the limiting plate 170 to one end of the drug delivery tube 100, an annular connecting rod 172 is provided at the bottom of the limiting plate 170, and a connecting groove connected to the second radial sliding groove 171 is provided on the annular connecting rod 172, and a rotating annular groove 173 is provided at the upper end of the drug delivery tube 100, and the annular connecting rod 172 at the bottom of the limiting plate 170 is connected to the rotating annular groove 173 so that the limiting plate 170 is rotatably connected to the drug delivery tube 100. At the same time, in order to limit the even number of support rods 310 to move only along the radial direction of the drug delivery tube 100, a limiting rod 311 is fixedly connected to the support rod 310, such as Figure 8 and Fig. 9 As shown, the limiting rod 311 is vertically and fixedly connected to one end of the support rod 310 close to the limiting plate 170, and the limiting rod 311 is slidably inserted into the second radial slot 171 of the limiting plate 170, so that the support rod 310 can only move radially along the dosing tube 100.

[0057] In a further embodiment, the elastic plate 320 of the present invention is made of medical rubber or medical plastic, which has good tolerance to human tissue and physiological environment and generally does not cause immune response in the human body, such as allergic reaction, inflammatory reaction, etc.

[0058] Specifically, in the embodiment of the present invention, a spiral groove 230 is provided on the outer circumference of the piston column 200, and a rotating groove 151 is provided on the gripping handle 150. A convex column 152 is provided on the inner circumferential wall of the rotating groove 151. The piston column 200 passes through the rotating groove 151. The convex column 152 in the rotating groove 151 is located in the spiral groove 230 of the piston column 200. When the piston column 200 moves axially relative to the dosing tube 100, the piston column 200 rotates around its own axis under the action of the spiral groove 230 and the convex column 152. In order to facilitate the piston column 200 to squeeze out the medicine in the dosing tube 100, a sealing sleeve 220 is fixedly provided on the outer periphery of the piston column 200, and the sealing sleeve 220 is in close contact with the inner wall of the dosing tube 100. When the piston column 200 moves axially relative to the dosing tube 100, the piston column 200 rotates, and the friction between the sealing sleeve 220 on the piston column 200 and the dosing tube 100 enables the piston column 200 to drive the dosing tube 100 to rotate, and then the pushing ring 140 on the outer periphery of the dosing tube 100 can push an even number of support rods 310 to move along the radial direction of the dosing tube 100, thereby continuously changing the supporting position of the support rods 310.

[0059] It should be noted that the friction force between the sealing sleeve 220 and the inner wall of the drug delivery tube 100 is greater than the force required for the push ring 140 to push an even number of support rings to move radially along the drug delivery tube 100 .

[0060] In a further embodiment, the number of the push rings 140 of the present invention is at least three, and the three push rings 140 are evenly distributed on the outer circumference of the dosing tube 100, that is, the three push rings 140 are respectively distributed at the upper end, middle and lower end of the dosing tube 100, so that the force on the support rod 310 can be more uniform, which facilitates the movement of an even number of support rods 310 along the radial direction of the dosing tube 100.

[0061] Of course, the number of the push rings 140 can also be four, five, etc., but the number should not be too large to avoid too many push rings 140 affecting the spraying of the drug solution into the drug tube 100.

[0062] Specifically, in the embodiment of the present invention, the inner wall of the drug delivery tube 100 has a tapered section 120 and a straight tube section 130, the tapered section 120 is located at the front end of the straight tube section 130, and the large end of the tapered section 120 is connected to the straight tube section 130, and a plurality of drug delivery holes 110 are provided on the side wall of the tapered section 120 and distributed along the axial direction of the drug delivery tube 100, thereby increasing the area of ​​the drug delivery tube 100 spraying the liquid medicine and increasing the area of ​​the vaginal inner wall covered by the liquid medicine. At the same time, the piston rod 200 has a tapered tip 210 so as to fit the tapered section 120 of the drug delivery tube 100, so that the tapered tip 210 of the piston rod 200 can contact the inner wall of the tapered section 120, and the use of this structural arrangement can make all drug delivery holes 110 on the surface of the tapered section 120 spray the liquid medicine continuously and evenly.

[0063] It can be understood that if the structural setting of the tapered tip 210 and the tapered section 120 is not adopted, the several dosing holes 110 distributed axially on the dosing tube 100 will be blocked when the piston rod 200 passes over the dosing hole 110, thereby causing uneven spraying of the liquid medicine. However, by adopting the above-mentioned structure, when the piston rod 200 passes over the dosing hole 110, the piston rod 200 does not block the dosing hole 110, so that the dosing hole 110 is evenly sprayed with the liquid medicine.

[0064] Specifically, the several drug delivery holes 110 in the present invention are perpendicular to the outer wall of the drug delivery tube 100 , so that the drug solution can be sprayed vertically on the inner wall of the vagina, thereby improving the uniformity of spraying of the drug delivery holes 110 .

[0065] In a further embodiment, in order to facilitate the operator to better push the piston column 200 and not affect the rotation of the piston column 200, a pressing block 240 is rotatably provided on the end of the piston column 200 away from the dosing tube 100, that is, on the rear end of the piston column 200. When the operator pushes the piston column 200, the operator will contact the pressing block 240. The operator pushes the pressing block 240 to push the piston column 200 to move forward to squeeze out the medicine in the dosing tube 100. When the piston column 200 moves forward, the action of the spiral groove 230 and the protrusion 152 causes the piston column 200 to rotate, and the operator pushes the pressing block 240. The pressing block 240 does not limit the rotation of the piston column 200, which means that the piston column 200 moves forward and rotates at the same time, so that the dosing tube 100 rotates to spray the medicine on the inner wall of the vagina, and at the same time reciprocates to change the supporting position of the support rod 310, thereby improving the spraying area and spraying accuracy of the medicine.

[0066] The specific use method of a gynecological care applicator provided by the present invention is described in combination with the above embodiments:

[0067] Spraying liquid:

[0068] The required liquid medicine is loaded into the dosing tube 100. Since the diameter of the dosing hole 110 on the side wall of the dosing tube 100 is very small, the liquid medicine will not be discharged from the dosing tube 100 due to the tension of the liquid when the piston rod 200 does not move axially. In the initial state, the support rod 310 is in the first state, that is, the support rod 310 forms a regular dodecagon. The operator slowly inserts the gynecological care drug delivery device into the vagina, and the support rod 310 forming a regular dodecagon supports the vaginal wall, thereby stretching the folds of the inner wall of the vagina. The operator slowly pushes the pressing block 240. Since the pressing block 240 is rotatably connected to the piston column 200, the piston column 200 rotates and moves axially. The piston rod moves axially to squeeze the medicine inside the drug delivery tube 100, and the medicine is sprayed from several drug delivery holes 110. Since a sealing sleeve 220 is fixedly provided on the outer periphery of the piston column 200, there is a large friction between the sealing sleeve 220 and the drug delivery tube 100, thereby being able to drive the drug delivery tube 100 to rotate. The rotation of the drug delivery tube 100 improves the uniformity of the drug spraying.

[0069] Change support position:

[0070] At the same time, when the dosing tube 100 rotates, it drives the three pushing rings 140 on the periphery, and the protrusions 141 on the pushing ring 140 can push an even number of support rods 310. Since the two ends of the support rod 310 are respectively located in the first radial groove 161 of the limiting ring 160 and the second radial groove 171 of the limiting plate 170, when the support rod 310 is pushed by the pushing ring 140, the even number of support rods 310 are switched from the first state to the second state under the action of the elastic plate 320 and the pushing ring 140, so that the originally formed regular dodecagon is switched to a regular hexagon. As the pushing ring 140 rotates, the first state and the second state switch back and forth, thereby continuously changing the supporting position of the support rod 310 and the inner wall of the vagina, avoiding dead angles when spraying the liquid medicine. In addition, with the rotation of the dosing tube 100, the liquid medicine can be sprayed on the vaginal wall more evenly.

[0071] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
