[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] Reference Figures 1 to 10 The technical solution provides a drug delivery device for gynecological care, which includes an insertion mechanism, an extension mechanism and a recovery mechanism, which can apply medicine according to the actual diseased area inside the patient's vagina, avoid wasting medicine liquid, and after the patient's drug delivery is completed, the excess medicine liquid can be collected.

[0031] Furthermore, the insertion mechanism can achieve the effect of infusing fluid into the patient's vagina, which includes a cannula 10, a strip groove 11, a first through-port 12, a slide groove 13, a limiting groove 14, a first arc groove 15 and a second arc groove 16 of the cannula 10, the strip groove 11 is respectively interconnected with the first arc groove 15 and the second arc groove 16, the strip groove 11 is located between the first arc groove 15 and the second arc groove 16, the strip groove 11 and the first through-port 12 are interconnected, the first through-port 12 is located directly below the strip groove 11, slide grooves 13 are provided on both sides of the strip groove 11, the limiting groove 14 is interconnected with the slide groove 13, and the limiting groove 14 is located at the top of the slide groove 13, and a liquid inlet 17 is provided inside the cannula 10.

[0032] Furthermore, the liquid inlet part 17 includes a pressing rod 171 inside the insertion tube 10, a sealing plug 172 is provided at one end of the pressing rod 171, and a one-way tube 173 is provided at the center position of one end of the pressing rod 171 away from the sealing plug 172, so that the liquid inside the one-way tube 173 can only flow in one direction, and one end of the one-way tube 173 passes through the sealing plug 172.

[0033] When in use, the staff pumps the liquid medicine into the interior of the cannula 10 through the one-way tube 173 . As the liquid medicine in the cannula 10 gradually increases, the sealing plug 172 drives the pressing rod 171 to move to the outside of the cannula 10 .

[0034] Furthermore, the extending mechanism can prevent the lifting block 20 from causing damage to the patient's vagina during the insertion of the cannula 10 into the vagina when the lifting block 20 is not extended. After the cannula 10 is inserted, the lifting block 20 with the absorbent sponge 252 can be extended to apply medicine to the patient's affected area. The lifting block 20 includes a lifting block 20 inside the strip groove 11, and sliders 21 are installed on both sides of the lifting block 20. The sliders 21 are located inside the slide groove 13. The lifting block 20 is provided with a V-shaped groove 22, a second through-hole 23 and a liquid collecting groove 24. The V-shaped groove 22 is located at the top of the lifting block 20. There are multiple liquid collecting grooves 24, which are respectively located on both sides of the second through-hole 23. The lifting block 20 is provided with a liquid absorbing part 25 and a driving part 26. The second through-hole 23 is provided with an infusion part 27, and the infusion part 27 is provided with a follower part 28.

[0035] Furthermore, the liquid absorption part 25 includes an L-shaped block 251 on the V-shaped groove 22. There are two L-shaped blocks 251, which are opposite to each other. A liquid absorption sponge 252 is arranged on the L-shaped block 251, and an L-shaped groove adapted to the L-shaped block 251 is opened at the bottom of the liquid absorption sponge 252.

[0036] Furthermore, the length of the L-shaped block 251 is half of the length of the lifting block 20 .

[0037] During use, after the absorbent sponge 252 has been used, the absorbency of the absorbent sponge 252 decreases. For subsequent application of medicine, the absorbent sponge 252 can be removed from the lifting block 20 and replaced.

[0038] Furthermore, the driving part 26 includes a first spring 261 at the bottom of the lifting block 20. There are two first springs 261, which are respectively located on both sides of the bottom of the lifting block 20. The bottom of the first spring 261 is connected to a fixing plate 262, which is installed on the inner wall of the strip groove 11.

[0039] Specifically, when the sliding block 21 is located on the bottom surface of the sliding groove 13 , the first spring 261 is in a contracted state, and the first spring 261 is used to drive the lifting block 20 to rise.

[0040] Furthermore, the infusion part 27 includes a lifting tube 271 inside the second through-port 23, the top of the lifting tube 271 is located inside the lifting block 20, the bottom of the lifting tube 271 is located inside the first through-port 12, a liquid inlet 272 is opened on the side wall of the lifting tube 271, a rubber ring 273 and a conical plug 274 are fixedly provided on the side wall of the lifting tube 271, the rubber ring 273 is located above the conical plug 274, the liquid inlet 272 is located at one end adjacent to the conical plug 274, and the liquid inlet 272 is located between the rubber ring 273 and the conical plug 274.

[0041] Specifically, the lifting block 20 can be lifted and lowered on the side wall of the lifting tube 271. The lifting block 20 and the lifting tube 271 do not affect each other. When the conical plug 274 follows the lifting tube 271 to descend to the interior of the cannula 10, the conical plug 274 is detached from the interior of the first through-hole 12. At this time, the first through-hole 12 and the interior of the cannula 10 are interconnected. At this time, the medicine inside the cannula 10 can enter the interior of the lifting tube 271 through the liquid inlet 272. When the medicine contacts the absorbent sponge 252, it will be absorbed by the absorbent sponge 252. After the absorption, the absorbent sponge 252 is used to apply to the patient's diseased area.

[0042] Furthermore, the follower 28 includes a tooth groove 281 on the outer wall of the lifting tube 271. The number of the tooth grooves 281 is two, and the two tooth grooves 281 are respectively located on both sides of the lifting tube 271. A tooth block 282 is provided on the side wall of the slider 21, and a gear 283 is installed on the inner wall of the strip groove 11. The gear 283 is respectively engaged with the tooth block 282 and the tooth groove 281. A first inclined surface 284 is provided on the side of the slider 21 adjacent to the outlet of the cannula 10.

[0043] During use, when the slider 21 rises under the recovery of the first spring 261, the slider 21 can drive the tooth block 282 to rise, and when the tooth block 282 rises, it can drive the gear 283 to rotate, and when the gear 283 rotates, the gear 283 can drive the lifting tube 271 to move downward, thereby causing the conical plug 274 to detach from the inside of the first through-port 12, so that the medicine liquid contacts the absorbent sponge 252.

[0044] Specifically, through the arrangement of the conical plug 274 and the rubber ring 273, when the first spring 261 recovers, the resistance of the conical plug 274 and the rubber ring 273 can slow down the recovery speed of the first spring 261, thereby preventing the first spring 261 from quickly driving the lifting block 20 to rise and impacting the inside of the patient's vagina, thereby preventing the patient from feeling pain from being hit.

[0045] Furthermore, the recovery mechanism can collect the absorbent sponge 252 into the strip groove 11 after applying the medicine to the affected area, and squeeze the medicine liquid on the absorbent sponge 252 to collect it to avoid waste of the medicine liquid. It includes a second spring 30 inside the first arc groove 15, and a sealing part 31 is provided on the second spring 30. A push-pull part 32 is provided inside the limiting groove 14, and a pressing part 33 is connected to the push-pull part 32.

[0046] Furthermore, the sealing portion 31 includes an arc block 311 on the second spring 30 , and one end of the arc block 311 away from the second spring 30 is connected to an arc plate 312 , and a second inclined surface 313 is provided on the arc plate 312 .

[0047] Specifically, when one side of the arc block 311 contacts the inner wall of the first arc groove 15, the second spring 30 is in an extended state. At this time, one end of the arc plate 312 is located inside the second arc groove 16. At the same time, the inner walls of the arc plate 312 contact the top of the lifting block 20 respectively to seal the V-shaped groove 22.

[0048] During use, when the arc block 311 drives the arc plate 312 to move into the second arc groove 16, the second inclined surface 313 is set so that the bottom of the arc plate 312 can squeeze the absorbent sponge 252, so that the medicine inside the absorbent sponge 252 enters the liquid collecting tank 24 or the interior of the lifting tube 271. At the same time, the V-shaped groove 22 is sealed, and the arc plate 312 can prevent the medicine from leaking to the outside of the strip groove 11.

[0049] Furthermore, the push-pull portion 32 includes a first push rod 321 inside the limiting groove 14. The first push rod 321 is located at the top of the slider 21. Since the lifting block 20 is connected to the slider 21, when the slider 21 is restricted, the lifting block 20 will also be restricted. One end of the first push rod 321 is connected to a pull ring 322, and the pull ring 322 is sleeved on the outside of the pressing rod 171.

[0050] Specifically, when the first push rod 321 is completely located inside the limiting groove 14 , the lifting block 20 drives the liquid absorbing sponge 252 to be located inside the strip groove 11 , and at the same time, the arc block 311 drives the arc plate 312 to seal the strip groove 11 .

[0051] During use, when the user drives the pull ring 322, the pull ring 322 can drive the first push rod 321 to be gradually pulled out from the limit groove 14. As the first push rod 321 is pulled out, the restriction on the slider 21 can be gradually released, so that the first spring 261 can resume driving the lifting block 20 to rise. When the first push rod 321 is reinserted, the first inclined surface 284 on the slider 21 can be used to guide the slider 21 to descend.

[0052] Furthermore, the pressing portion 33 includes a second push rod 331 on the pull ring 322 , and an arc-shaped slope groove 332 is formed on the arc block 311 , and the highest point of the arc-shaped slope groove 332 is adjacent to the arc-shaped plate 312 .

[0053] Specifically, when the second push rod 331 is located at the rightmost side of the arc-shaped slope groove 332, the arc block 311 drives the arc plate 312 to seal the strip groove 11; when the second push rod 331 is located at the leftmost side of the arc-shaped slope groove 332, the lifting block 20 drives the absorbent sponge 252 to contact the inner wall of the patient's vagina.

[0054] During use, when the user drives the pull ring 322, the pull ring 322 can drive the first push rod 321 and the second push rod 331 to move together. When the second push rod 331 moves toward the outside of the tube 10, the restriction on the arc block 311 can be gradually released, so that the second spring 30 can drive the arc block 311 to move, so that the arc block 311 drives the arc plate 312 to open the strip groove 11, making it convenient for the subsequent conical plug 274 to enter the interior of the tube 10.

[0055] Furthermore, the thickness of the arc plate 312 is compatible with the thickness of the second arc groove 16, so that the arc plate 312 is more stable when inserted into the second arc groove 16; the outer wall of the insertion tube 10 is marked with scales to facilitate the user to control the depth of the insertion of the insertion tube 10 into the vagina.

[0056] Working principle: When it is necessary to apply medicine to the inside of the patient's vagina, the user first transports the medicine liquid to the inside of the cannula 10 through the one-way tube 173. As the medicine liquid gradually enters, the sealing plug 172 is driven to move to the outside of the cannula 10, and the sealing plug 172 drives the pressing rod 171 to move together. Then, the user determines the position and area of ​​the affected part inside the vagina according to the examination results of the hospital, and the user inserts the cannula 10 into the patient's vagina according to the scale on the cannula. When it reaches the specified position, the user drives the pull ring 322, and the pull ring 322 drives the first push rod 321 and the second push rod 331 to move to the outside of the cannula 10. According to the area of ​​the vaginal affected part, the user controls the movement distance of the driving pull ring 322. When the first push rod 321 disengages from a slider 21, the second push rod 331 is completely disengaged from the inside of the arc-shaped slope groove 332. At this time, under the action of the second spring 30 of the first spring 261, when the second spring 30 When the lifting block 20 is lifted up, the second spring 30 can drive the arc block 311 to move, and the arc block 311 drives the arc plate 312 to move, so that the arc plate 312 releases the seal of the strip groove 11. At this time, since the lifting block 20 loses the restriction of the arc plate 312, the first spring 261 can drive the lifting block 20 to rise. When the lifting block 20 is lifted up inside the strip groove 11, the lifting block 20 drives the slider 21 to rise inside the slide groove 13, and the slider 21 drives the tooth block 282 to rise, and the tooth block 282 drives the gear 283 to rotate forward, and the gear 283 drives the lifting tube 271 to descend. The lifting tube 271 is blocked by the rubber ring 273 and the tapered plug 274 and slowly descends, so that the rotation speed of the gear 283 decreases, so that the first spring 261 can only slowly recover, and finally the lifting block 20 slowly rises, and the lifting block 20 drives the liquid-absorbing sponge 252 inside the V-shaped groove 22 to contact the patient's affected part.

[0057] As the lifting block 20 gradually rises, the lifting tube 271 moves downward, allowing the conical plug 274 to enter the interior of the insertion tube 10. At this time, the medicinal liquid can contact the absorbent sponge 252 through the liquid inlet 272 and the lifting tube 271, and the medicinal liquid is absorbed by the absorbent sponge 252. When the user rotates the insertion tube 10, the insertion tube 10 drives the lifting block 20 to rotate, and the lifting block 20 drives the absorbent sponge 252 to wipe the inner wall of the vagina of the affected area to apply the medicine.

[0058] When the medication is applied, in order to avoid wasting the medicine on the absorbent sponge 252, the user can drive the pull ring 322 so that the pull ring 322 drives the first push rod 321 and the second push rod 331 to be inserted into the interior of the cannula 10, and the first push rod 321 squeezes the first inclined surface 284 so that the slider 21 drives the tooth block 282 to descend, and the tooth block 282 drives the gear 283 to rotate in the opposite direction, and the gear 283 drives the lifting tube 271 to rise. When the lifting tube 271 rises, it drives the conical plug 274 to be retracted into the interior of the first through-hole 12 to prevent the medicine inside the cannula 10 from continuing to enter the interior of the lifting tube 271. At the same time, when the first push rod 321 moves, the second push rod 331 is driven by the pull ring 322 to squeeze the arc slope groove 332, so that the arc block 311 moves The second spring 30 is squeezed and contracted, and the arc block 311 drives the arc plate 312 to be inserted into the second arc groove 16. During the movement of the arc plate 312, the second inclined surface 313 on the arc plate 312 can squeeze the liquid-absorbing sponge 252, so that the liquid-absorbing sponge 252 is retracted into the inside of the V-shaped groove 22, so that the medicine in the liquid-absorbing sponge 252 enters the inside of the lifting tube 271 and the liquid collecting tank 24. When the arc plate 312 is completely inserted into the inside of the second arc groove 16, the liquid-absorbing sponge 252 is squeezed and the V-shaped groove 22 is sealed at the same time, so as to prevent the medicine inside the liquid collecting tank 24 and the lifting tube 271 from flowing out after the cannula 10 is pulled out. When the medicine is applied next time, the medicine inside the liquid collecting tank 24 and the lifting tube 271 can continue to be used to avoid waste.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention 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 invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
