The embodiments of the present invention will be described below according to the overall structure of the present invention.

[0039] Refer to Figures 1 to 7, in the embodiment of the present invention, a gynecological medicine application device capable of realizing uniform medicine application includes: a medicine storage member 1 for temporarily storing medicine, a closing device 2 is rotatably connected to the bottom end of the medicine storage member 1, and a medicine outlet cylinder 3 is inserted into the bottom end of the closing device 2. Through the closing device 2, the medicine storage member 1 can be switched between a discharging state communicating with the medicine outlet cylinder 3 and a closed state not communicating with the medicine outlet cylinder 3. A feeding member 4 for transporting the medicine in the medicine storage member 1 into the medicine outlet cylinder 3 is rotatably arranged in the medicine storage member 1. The feeding member 4 penetrates through the closing device 2 and the medicine outlet cylinder 3. A medicine application device 5 for discharging the medicine in the medicine outlet cylinder 3 and applying it to the affected area is arranged on the medicine outlet cylinder 3;

[0040] The medicine storage member 1 is composed of a first cylinder body 11, a connecting cylinder 12 and a second cylinder body 13. The first cylinder body 11 and the second cylinder body 13 have the same diameter, and the inner diameter of the connecting cylinder 12 is the same as the outer diameter of the first cylinder body 11. Among them, the inner wall of the connecting cylinder 12 is fixedly connected to the outer wall of the first cylinder body 11, and the inner wall of the connecting cylinder 12 is threadedly connected to the outer wall of the second cylinder body 13;

[0041] The closing device 2 includes a lower baffle 22 inserted into the top end of the medicine outlet cylinder 3. The cross-section of the lower baffle 22 is U-shaped. An upper baffle 21 is rotatably connected to the top end of the lower baffle 22. The upper baffle 21 is annular. The feeding member 4 penetrates through the upper baffle 21 and the lower baffle 22. A first discharge groove 215 is formed through the upper baffle 21. The first discharge groove 215 is C-shaped. A limiting block 216 is fixedly connected in the first discharge groove 215. The limiting block 216 is C-shaped. A second discharge groove 222 is formed through the lower baffle 22. The second discharge groove 222 has the same size as the first discharge groove 215.

[0042] A limiting groove 223 is formed at the bottom end of the lower baffle 22. The limiting groove 223 is C-shaped, and the limiting groove 223 communicates with the second discharge groove 222 and is slidably inserted with the limiting block 216;

[0043] Among them, when the medicine in the medicine storage member 1 is used up, rotate the feeding member 4 to drive the upper baffle 21 to rotate, so that the limiting block 216 is inserted into the limiting groove 223 to the limit position. At this time, the first discharge groove 215 and the second discharge groove 222 are misaligned, so that the medicine storage member 1 is in a closed state. Then, pull the medicine storage member 1 to separate the closing device 2 from the medicine outlet cylinder 3. Then, rotate the connecting cylinder 12 to release the threaded connection between the connecting cylinder 12 and the second cylinder body 13, separate the connecting cylinder 12 from the second cylinder body 13, fill the medicine into the first cylinder body 11, and then reconnect the connecting cylinder 12 and the second cylinder body 13 to restore the medicine storage member 1 and the closing device 2 into a whole, and connect the closing device 2 to the medicine outlet cylinder 3, and then the medicine application can be continued.

[0044] Refer to Figures 2 to 8, the feeding member 4 is composed of a rotating head 41, a first feeding rod 42, a second feeding rod 43 and a third feeding rod 44 connected in sequence. The first feeding rod 42, the second feeding rod 43 and the third feeding rod 44 are each composed of a group of straight rods and spiral pushing plates wound around the outside. The three groups of spiral pushing plates are respectively in contact with the inner walls of the first cylinder body 11, the second cylinder body 13 and the medicine discharging cylinder 3. Anti-slip grooves are evenly arranged on the outside of the rotating head 41. Among them, a connecting groove 431 is arranged at the bottom end of the second feeding rod 43. The connecting groove 431 is cross-shaped. A connecting rod 432 is fixedly connected to the top end of the second feeding rod 43. The connecting rod 432 is cross-shaped. The cross-shaped connecting groove 431 and the cross-shaped connecting rod 432 have the same size. And a connecting groove 431 is also arranged at the bottom end of the first feeding rod 42. A connecting rod 432 is also fixedly connected to the top end of the third feeding rod 44. The top end of the first feeding rod 42 penetrates through the first cylinder body 11 and is fixedly connected to the rotating head 41. And the first feeding rod 42 is rotatably connected to the first cylinder body 11. The connecting rod 432 at the top end of the second feeding rod 43 is inserted into the connecting groove 431 at the bottom end of the first feeding rod 42. The connecting rod 432 at the top end of the third feeding rod 44 is inserted into the connecting groove 431 at the bottom end of the second feeding rod 43. The straight rod in the second feeding rod 43 penetrates through the upper baffle 21 and the lower baffle 22 and is rotatably connected to the upper baffle 21 and the lower baffle 22. When the rotating head 41 drives the feeding rod to rotate, the spiral pushing plate will push the medicine in the first cylinder body 11 towards the bottom end inside the medicine discharging cylinder 3. In this process, the medicine continuously moves towards the bottom of the medicine discharging cylinder 3 under the action of the spiral pushing plate, thereby realizing the feeding function.

[0045] Adopting the above solution: By controlling the rotation of the feeding member 4 through the rotating head 41, the user can, according to needs, precisely control the dosage of medicine by controlling the rotation angle and speed of the rotating head 41, so as to meet different treatment requirements. The design of the spiral pushing plate can make the medicine move more evenly towards the bottom of the medicine discharging cylinder 3 during the pushing process, ensure that the medicine can continuously and stably enter the medicine discharging cylinder 3, and further ensure that the medicine applying device 5 can evenly apply the medicine to the affected area.

[0046] Refer to Figures 5 to 8, the closing device 2 further includes a cavity 211 formed on the outer side of the second feeding rod 43. There are four groups of cavities 211, which are evenly distributed on the outer side of the second feeding rod 43. A linkage block 212 is slidably inserted into each cavity 211. The linkage block 212 is V-shaped. One end of each group of linkage blocks 212 is fixedly connected to a first spring 213, and one end of the first spring 213 is fixedly connected to the inner wall of the cavity 211. A linkage groove 214 is formed on the inner side of the upper baffle 21. There are four groups of linkage grooves 214. The linkage block 212 is adapted to the linkage groove 214. A synchronization block 224 is fixedly connected to the outer side of the medicine delivery cylinder 3. There are four groups of synchronization blocks 224, which are evenly distributed on the outer side of the medicine delivery cylinder 3. A synchronization groove 221 is formed on the inner side of the lower baffle 22. There are four groups of synchronization grooves 221. Each synchronization block 224 is inserted into a synchronization groove 221. An expansion ring 31 is rotatably connected to the outer side of the medicine delivery cylinder 3. A spreading block 32 is rotatably connected to the bottom end of the medicine delivery cylinder 3. The spreading block 32 is circular, and the outer diameter of the expansion ring 31 is the same as the outer diameter of the spreading block 32. When the linkage block 212 drives the upper baffle 21 to rotate under the action of the linkage groove 214, the limiting block 216 in the limiting groove 223 exits the limiting groove 223 until the first discharge groove 215 is aligned with the second discharge groove 222. At this time, the limiting block 216 abuts against the inner wall of the second discharge groove 222, generating a reverse force, causing the linkage block 212 to move towards the inside of the cavity 211, and the first spring 213 is compressed under force. The alignment state of the first discharge groove 215 and the second discharge groove 222 is maintained by the spring force, enabling the medicine storage member 1 to communicate with the medicine delivery cylinder 3, and the medicine can enter the medicine delivery cylinder 3 from the medicine storage member 1.

[0047] Adopting the above solution: Through the cooperation of the upper baffle 21 and the lower baffle 22, by utilizing the structures of the first discharge groove 215, the second discharge groove 222, the limiting block 216 and the limiting groove 223, the closing and opening functions of the medicine storage member 1 can be effectively realized. When not in use or when the medicine in the medicine storage member 1 is used up, it can be well sealed to prevent medicine leakage and ensure the preservation quality and safety of the medicine.

[0048] Refer to Figures 9 to 12, the medicine application device 5 includes a medicine application groove 51 penetratingly opened at the bottom end of the inner wall of the medicine delivery cylinder 3. There are four groups of medicine application grooves 51, which are evenly distributed on the outer side of the medicine delivery cylinder 3. Two mounting plates 52 are fixedly connected in each group of medicine application grooves 51. The two mounting plates 52 are symmetrically distributed on both sides inside the medicine application groove 51. A discharging member 53 is arranged on the mounting plate 52. The discharging member 53 includes two second springs 533 fixedly connected to the mounting plate 52. There are two groups of second springs 533, and each group of second springs 533 is fixedly connected to one mounting plate 52. One end of each group of second springs 533 is fixedly connected to a connecting plate 532. One end of the connecting plate 532 is fixedly connected to a discharging block 531. The two connecting plates 532 are symmetrically distributed on both sides of the discharging block 531. The distance between the two mounting plates 52 is the same as the length of the discharging block 531. A discharging groove 534 is penetratingly opened on each discharging block 531. The discharging groove 534 is L-shaped. One end of the discharging groove 534 penetrates the top end of the discharging block 531, and the other end penetrates the inner side of the discharging block 531. The discharging groove 534 communicates with the medicine application groove 51. When the rotating head 41 is rotated and the feeding rod rotates to push the medicine in the first cylinder body 11 towards the bottom end inside the medicine delivery cylinder 3, the medicine inside the medicine delivery cylinder 3 is pressed down and enters the discharging groove 534 inside the medicine application groove 51. As the medicine continuously enters the discharging groove 534, the medicine generates an outward thrust on the discharging block 531, pushing the discharging block 531 to move outward inside the medicine application groove 51. In this process, the second spring 533 is stretched under force. When the discharging groove 534 at the top end of the discharging block 531 is pushed out of the medicine application groove 51, the medicine is extruded from the discharging groove 534 at the top end of the discharging block 531 under the action of pressure. After a certain amount of medicine is extruded, the rotation of the feeding member 4 is stopped. At this time, since some medicine is extruded, the thrust of the medicine inside the medicine delivery cylinder 3 on the discharging block 531 is reduced, and the second spring 533 returns to its original length, driving the discharging block 531 to reset. During the reset process of the discharging block 531, the top end of the discharging block 531 abuts against the inner top end of the medicine application groove 51, scraping off the medicine at the top end of the discharging block 531 to prepare for the next discharging.

[0049] Adopting the above solution: Through the cooperation of the second spring 533 and the discharging block 531, the discharging can be automatically controlled according to the pressure of the medicine. When the pressure of the medicine reaches a certain level, the discharging block 531 will move and discharge the medicine, which can avoid discharging too much medicine at one time, realizing precise control of the discharging amount, helping to apply the medicine evenly, enabling the medicine to be applied to the affected area according to a suitable dose. The design of the L-shaped discharging groove 534 makes the medicine enter and exit more orderly. During the process of the medicine entering the discharging groove 534, the discharging groove 534 can play a guiding and buffering role to prevent the medicine from flowing too fast or disorderly and causing blockage. At the same time, the reset action of the discharging block 531 can scrape off the excess medicine at the top end, avoiding waste caused by the medicine remaining at the top end of the discharging block 531 and ensuring the effective utilization of the medicine.

[0050] Refer to Figures 9 to 10, the medicine application device 5 further includes a medicine application plate 54 fixed to the outer side of the medicine delivery cylinder 3. The medicine application plate 54 is spiral, wound around the outer side of the medicine delivery cylinder 3, and is located between the expansion ring 31 and the expansion block 32. The diameter of the spiral medicine application plate 54 is smaller than the diameter of the expansion ring 31. The top end of the medicine application plate 54 is fixedly connected with a guide plate 55. The cross-section of the medicine application plate 54 is rectangular, and the cross-section of the guide plate 55 is triangular, so that the medicine on the guide plate 55 slides outward. The end face of the medicine application plate 54 is fixedly connected with a shovel plate 56. The shovel plate 56 is in the shape of a triangular prism, and its two straight side faces are respectively attached to the top face of the expansion block 32 and the end face of the medicine application plate 54. The end face of the guide plate 55 is fixedly connected with a scraping plate 57. The scraping plate 57 abuts against the outer side of the medicine delivery cylinder 3. The scraping plate 57 is at the same height as the medicine application groove 51, and the surface of the scraping plate 57 close to the medicine application groove 51 is arc-shaped. A cooperation groove 59 is formed on the outer side of the lower baffle 22. There are four groups of cooperation grooves 59, which are evenly distributed on the outer side of the lower baffle 22. A cooperation cylinder 58 is slidably inserted on the outer side of the cooperation groove 59. The cooperation cylinder 58 is composed of an outer cylinder and four cooperation blocks fixedly connected to the inner wall of the outer cylinder. Each cooperation block is slidably inserted into a cooperation groove 59. A plurality of anti-slip grooves are evenly formed on the outer side of the outer cylinder in the cooperation cylinder 58. After the discharging member 53 extrudes the medicine out of the medicine application groove 51, the cooperation cylinder 58 inserted into the cooperation groove 59 on the outer side of the lower baffle 22 is rotated. Under the insertion action of the synchronization groove 221 and the synchronization block 224, the cooperation cylinder 58, the lower baffle 22 and the medicine delivery cylinder 3 rotate synchronously. At this time, the arc surface of the scraping plate 57 abuts against the medicine application groove 51, and the residual medicine on the medicine application groove 51 is scraped off. The shovel plate 56 shovels up the medicine extruded out of the discharging groove 534, so that the medicine moves onto the guide plate 55 and the medicine application plate 54. The guide plate 55 uses its own inclined plane to guide the medicine onto the medicine application plate 54. As the medicine accumulates, the amount of medicine accumulated on the medicine application plate 54 is greater than the area between the expansion ring 31 and the expansion block 32. When the spiral medicine application plate 54 starts to rotate, the medicine accumulated on it is applied to the affected area. After the medicine accumulated on the medicine application plate 54 is applied, the feeding member 4 is rotated continuously, so that the medicine continues to be extruded out of the medicine delivery cylinder 3, and then the cooperation cylinder 58 is rotated continuously to allow the medicine to continue to accumulate on the medicine application plate 54. Since the diameter of the medicine application plate 54 is smaller than that of the expansion ring 31 and the expansion block 32, as the spiral medicine application plate 54 rotates, the medicine applied to the affected area will thicken. When the medicine is too thick, the medicine application plate 54 will scrape off the too thick medicine on the affected area and, as the medicine application plate 54 rotates, bring the medicine to the affected area where the medicine has not been applied, realizing the uniform application of the medicine.

[0051] Using the above solution: Through the cooperation of the scraping plate 57 and the shoveling plate 56, residual drugs can be effectively collected, avoiding waste of drugs, transferring the drugs from different positions to the drug application plate 54, ensuring that as much drug as possible can be used for applying to the affected area, improving the utilization rate of the drug. The triangular cross-section of the guiding plate 55 can guide the drugs to be evenly distributed on the drug application plate 54, making the drug accumulation on the drug application plate 54 more uniform. During the rotation of the spiral drug application plate 54, the drugs can be evenly applied to the affected area. Moreover, when the drug layer is too thick, it can be automatically scraped off and redistributed, further ensuring the uniformity of drug application and contributing to improving the treatment effect.

[0052] The working principle of the present invention is as follows: When in use, first add medicine into the barrel body 11, then rotate the lower baffle 22 to make the limit block 216 insert into the limit groove 223 to the extreme position. At this time, the first discharge groove 215 and the second discharge groove 222 are misaligned. Then, threadedly connect the connecting cylinder 12 on the barrel body 11 with the barrel body 13, and make the connecting rod 432 at the top of the second feeding rod 43 in the barrel body 13 be inserted into the connecting groove 431 at the bottom of the first feeding rod 42 in the barrel body 11. At this time, the medicine is in the closed space formed by the barrel body 11, the connecting cylinder 12, the barrel body 13 and the closing device 2, and will not leak. Then, insert the connecting rod 432 at the top of the third feeding rod 44 in the medicine discharging cylinder 3 into the connecting groove 431 at the bottom of the second feeding rod 43 in the barrel body 13. At the same time, insert the synchronous block 224 at the outer top of the medicine discharging cylinder 3 into the synchronous groove 221 inside the lower baffle 22 to complete the assembly of the device. After that, place the area of the medicine discharging cylinder 3 between the expanding ring 31 and the expanding block 32 at the place in the patient's body where medicine needs to be applied. Subsequently, rotate the rotating head 41 to drive the first feeding rod 42, the second feeding rod 43 and the third feeding rod 44 to rotate. During the rotation process, the linkage block 212 on the side of the second feeding rod 43 rotates synchronously, and under the action of the linkage groove 214, drives the upper baffle 21 to rotate, so that the limit block 216 in the limit groove 223 exits the limit groove 223 until the first discharge groove 215 is aligned with the second discharge groove 222. At this time, the limit block 216 abuts against the inner wall of the second discharge groove 222. Under the acting force of the abutment, a force opposite to the rotation of the upper baffle 21 driven by the second feeding rod 43 is generated, and under the action of the reverse force, the linkage block 212 moves towards the inside of the cavity 211. During the moving process, the first spring 213 is compressed by the force, until the linkage block 212 is completely retracted into the cavity 211 to keep the first discharge groove 215 aligned with the second discharge groove 222. And when the rotating head 41 drives the first feeding rod 42, the second feeding rod 43 and the third feeding rod 44 to rotate, the spiral pushing plates in the first feeding rod 42, the second feeding rod 43 and the third feeding rod 44 push the medicine in the barrel body 11 towards the inner bottom end of the medicine discharging cylinder 3. During the continuous pushing process, the medicine in the medicine discharging cylinder 3 will be continuously pressed down until the medicine enters the discharge groove 534 and pushes the discharge block 531 to move outward in the medicine application groove 51, and the second spring 533 is stretched by the force. When the discharge groove 534 at the top of the discharge block 531 is pushed out of the medicine application groove 51, the medicine will be extruded from the discharge groove 534 at the top of the discharge block 531 under the action of the pressure. When a certain amount of medicine is extruded, stop the rotation of the feeding member 4. Since part of the medicine is extruded, the thrust of the medicine in the medicine discharging cylinder 3 on the discharge block 531 is reduced, so that the second spring 533 returns to its original length and drives the discharge block 531 to reset. During the reset process of the discharge block 531, the top of the discharge block 531 abuts against the inner top of the medicine application groove 51 to scrape off the medicine at the top of the discharge block 531. Subsequently, rotate the cooperation cylinder 58 inserted into the cooperation groove 59 outside the lower baffle 22, and under the action of the insertion of the synchronous groove 221 and the synchronous block 224,Synchronously rotate the cooperation cylinder 58, the lower baffle 22 and the medicine delivery cylinder 3. During rotation, the arc surface of the scraping plate 57 abuts against the medicine loading groove 51, scraping off the residual medicine on the medicine loading groove 51, and shoveling up the medicine extruded from the discharge chute 534 under the action of the shoveling plate 56, causing the medicine to move onto the guiding plate 55 and the medicine loading plate 54. Under the action of the inclined surface of the guiding plate 55, the medicine is guided onto the medicine loading plate 54, so that the medicine piled up on the medicine loading plate 54 is more than that between the expanding ring 31 and the expanding block 32. Under the action of its spiral shape, the medicine piled up on the medicine loading plate 54 is smeared on the affected area. When the medicine piled up on the medicine loading plate 54 is applied, continue to rotate the feeding member 4, extruding the medicine out of the medicine delivery cylinder 3 continuously. Then continue to rotate the cooperation cylinder 58, causing the medicine to continue to pile up on the medicine loading plate 54. And because the diameter of the medicine loading plate 54 is smaller than that of the expanding ring 31 and the expanding block 32, as the spiral medicine loading plate 54 rotates, the medicine smeared on the affected area will thicken. When the medicine is too thick, the medicine loading plate 54 will scrape off the too thick medicine on the affected area and, as the medicine loading plate 54 rotates, bring the medicine to the affected area where the medicine has not been smeared. When the medicine in the medicine storage member 1 is used up, reverse the feeding member 4, causing the feeding member 4 to drive the upper baffle 21 to rotate, so that the limiting block 216 is inserted into the extreme position in the limiting groove 223. At this time, the first discharge chute 215 and the second discharge chute 222 are misaligned, making the medicine storage member 1 in a closed state. Then pull the medicine storage member 1, causing the synchronous block 224 to withdraw from the synchronous groove 221, and the connecting rod 432 at the top of the third feeding rod 44 to withdraw from the connecting groove 431 at the bottom of the second feeding rod 43, separating the closing device 2 from the medicine delivery cylinder 3. Then push the cooperation cylinder 58, causing the cooperation cylinder 58 to slide outside the lower baffle 22, exposing the connecting cylinder 12. Then rotate the connecting cylinder 12, releasing the threaded connection between the connecting cylinder 12 and the second cylinder body 13, and making the connecting rod 432 at the top of the second feeding rod 43 withdraw from the connecting groove 431 at the bottom of the first feeding rod 42, so as to separate the connecting cylinder 12 from the second cylinder body 13, filling the medicine into the first cylinder body 11. After that, reconnect the connecting cylinder 12 and the second cylinder body 13, making the medicine storage member 1 and the closing device 2 restored to a whole, and connecting the closing device 2 with the medicine delivery cylinder 3, then the medicine application can continue; Through the structural design of the medicine storage member 1 and the feeding member 4, when the medicine in the first cylinder body 11 is used up, there is no need to take out the whole device from the patient's body for filling. Just disassemble the medicine storage member 1 and the feeding member 4, then the medicine filling can be carried out. This process greatly reduces the unnecessary interference to the patient, avoids the physical discomfort and psychological burden brought to the patient by taking and placing the device multiple times. At the same time, it reduces the number of contacts between the device and the external environment, effectively reducing the risk of bacteria or pathogens invading the patient's body, and maximizing the safety of the patient during the treatment process. Through the mutual cooperation of the first discharge chute 215, the second discharge chute 222, the limiting block 216 and the limiting groove 223 in the closing device 2, when the device is idle or the medicine is exhausted, it can accurately block the channel between the medicine storage member 1 and the medicine delivery cylinder 3, effectively preventing medicine leakage, whether during storage or transportation,Both can ensure the stability and safety of the drug, avoid drug waste and pollution caused by leakage. Through the cooperation of the limit block 216 and the limit groove 223 in the closing device 2, when the upper baffle 21 rotates, the limit block 216 can be separated from or docked with the limit groove 223, so that when the feeding member 4 rotates continuously, the upper baffle 21 and the lower baffle 22 can maintain a connected state, greatly improving the convenience and flexibility of the device, and effectively saving time and energy in actual application scenarios. Through the cooperation of the second spring 533, the connecting plate 532 and the discharging block 531 in the medicine applying device 5, it can be intelligently adjusted according to the change of the drug pressure in the medicine cylinder 3, effectively controlling the discharging amount each time, avoiding excessive or insufficient discharge of the drug, ensuring the accuracy of the medicine dosage, providing a stable and reliable drug supply for disease treatment, and improving the stability of the treatment effect. Through the spiral design of the medicine applying plate 54 in the medicine applying device 5 and the guiding plate 55, the drug can be evenly applied to the affected area. The triangular cross-section of the guiding plate 55 causes the drug to slide outward and be evenly distributed on the medicine applying plate 54, so that the drug will not accumulate or be omitted during application, ensuring uniform coverage of the drug on the affected area, helping to improve the absorption efficiency of the drug, promoting the smooth progress of the treatment process, and reducing problems such as poor treatment effect that may be caused by uneven drug application.,
