[0037] The specific preparation process of the Chinese medicine spray comprises the following steps:

[0038] Step 1: first remove the tank cover 2, weigh the raw materials of Panax notoginseng, safflower, Corydalis yanhusuo, Galla chinensis, clove, Bletilla striata, and mint in proportion to each other by weight, grind them into coarse powder, filter the raw materials through the filter plate 11 for the first time and then put them into the tank body 1, and put another package of Indigo naturalis into the tank body 1 through the delivery port 6;

[0039] Step 2: Then pour 20000 ml of 38-40% ethanol solution into the tank body 1 and reinstall the tank cover 2 to the bottom of the tank body 1;

[0040] Step 3: Then soak the raw materials, and drive the rotating shaft 7 and the rotating plate to rotate through the first motor 5, fully stir the raw materials, weigh the proportion of borneol and borax in the middle, pour them into the tank 1 after dissolving, and add 0.3% mogroside to the solution in the later stage of soaking, mix well and filter the solution;

[0041] Step 4: Then, at the later stage of soaking, 0.3% mogroside is added to the solution so that the solution inside the tank 1 is mixed evenly;

[0042] Step 5: Finally, the moving port is exposed by moving the sealing plate 14, the raw material is transported to the temporal part of the delivery pipe 17, and filtered through the first filter screen 18 and the second filter screen 19 in the delivery pipe 17, and squeezed through the squeezing plate 16. The raw material is turned over by the adjusting structure 20 to the top of the first filter plate 11, and the turned raw material is squeezed again. After all the solution in the raw material is squeezed out, it is discharged from the discharge pipe 3 and packaged in spray bottles to obtain a Chinese medicine spray.

[0043] The ratio of Panax notoginseng, safflower, Corydalis yanhusuo, Galla chinensis, clove, Bletilla striata, mint and Indigo naturalis is as follows: Panax notoginseng: 360 parts, safflower: 360 parts, Corydalis yanhusuo: 300 parts, Galla chinensis: 360 parts, clove: 300 parts, Bletilla striata: 300 parts, mint: 300 parts, Indigo naturalis: 360 parts, borneol: 360 parts, borax: 280 parts and mogroside 30 parts.

[0044] When preparing the Chinese medicine spray, first weigh the proportion of Panax notoginseng, safflower, Corydalis yanhusuo, Chinese gallnut, clove, Bletilla striata and mint raw materials, then coarsely grind the above raw materials, when the raw materials are ground into coarse powder, open the tank cover 2, pour the ground raw materials into the tank body 1, filter through the filter plate 11 to filter the impurities inside the raw materials, and then put another package of Indigo into the tank body 1 through the conveying port 6, after the tank cover 2 is installed on the top of the tank body 1, soak the raw materials, and start the first motor 5 to drive the rotating shaft 7 and the first movable plate 8, the second movable plate 9 and the scraper 10 to rotate during the soaking process, so as to stir the soaked raw materials. When the second movable plate 9 rotates, the second electric push rod 15 and the squeezing plate 16 are driven to rotate on the top of the partition plate 12 to fully stir the soaked raw materials. When the soaking is completed, the squeezing plate 16 is rotated to separate from the moving port, and the sealing plate 14 is driven to move by starting the first electric push rod 13 to expose the moving port, so that the solution and raw materials inside the tank body 1 enter the inside of the conveying pipe 17, and are filtered through the first filter screen 18 and the second filter screen 19. The control valve 4 is controlled to discharge the solution from the discharge pipe 3 for collection. When the raw materials fall on the first filter screen 18 in the conveying pipe 17, the first motor 5 and the rotating shaft 7 are rotated to make the first filter screen 18 and the second filter screen 19 be filtered. The movable plate 8 and the second movable plate 9 drive the second electric push rod 15 to rotate, so that the extrusion plate 16 moves to the top of the movable port, and then the first electric push rod 13 is started to make the extrusion plate 16 move to the inside of the conveying pipe 17 through the movable port, so that the extrusion plate 16 moves to the top of the second filter plate 11, and the raw materials remaining on the second filter plate 11 are squeezed. After the solution is squeezed out, the second filter screen 19 is rotated through the adjustment structure 20 to separate the first magnetic block 21 from the second magnetic block 24. After the second filter screen 19 is turned over, the first magnetic block 21 connected to the adjustment structure 20 on one side of the second magnetic block 24 is attracted to each other, so that the residual The raw material falls onto the first filter screen 18, and then the second filter screen 19 is squeezed by the squeezing plate 16. The second filter screen 19 squeezes the first filter screen 18 downward, so that the telescopic rod is extended, and the fixing frame 203 drives the dual-axis motor 201 and the connecting rod 202 to move downward, so that the connecting spring 31 at the bottom of the first magnetic block 21 is compressed, and the sliders 25 on both sides of the movable plate 23 move along the slide groove. When the movable plate 23 moves to the bottom of the movable opening, the second filter screen 19 can squeeze the raw material on the first filter screen 18, so that the raw material can be fully squeezed, and the solution can be fully squeezed out, thereby improving the effect of solution leaching and facilitating use.

[0045] like Figure 1-4As shown, the filter plate 11 is located at the top of the tank body 1, the filter plate 11 is fixedly connected to the inner wall of the tank body 1, the first movable plate 8 is located on the outer surface of the rotating shaft 7 and is distributed in a linear array, the second movable plate 9 is movably connected to the inner wall of the first movable plate 8, the second movable plate 9 extends to the inside of the fixed groove away from one end of the scraper 10, a scraper block 26 is arranged at the bottom of the rotating shaft 7, the scraper block 26 and the scraper 10 are arranged in a cross shape, a fixed groove is opened inside the rotating shaft 7, and a moving structure 27 is arranged inside the fixed groove, the second electric push rod 15 and the extrusion plate 16 are located on both sides of the rotating shaft 7, and they are symmetrically arranged with the center of the rotating shaft 7, the extrusion plate 16 is located at the top of the partition plate 12, and the extrusion plate 16 is arranged corresponding to the moving port and the sealing plate 14.

[0046] The holes on the filter plate 11 are small and the raw materials are in coarse powder form, so that the coarse powder raw materials can be filtered and the impurities inside the coarse powder raw materials can be filtered out to prevent the impurities from affecting the soaking effect. The first movable plate 8 and the second movable plate 9 distributed in a linear array can drive the first movable plate 8 and the second movable plate 9 to rotate when the rotating shaft 7 rotates, so that the soaked raw materials can be stirred to facilitate full mixing. The moving structure 27 is installed through the fixed groove. When the moving structure 27 is started to make the second movable plate 9 move on the inner wall of the first movable plate 8, the second movable plate 9 pushes the scraper 10 to move toward the inner wall of the tank body 1, so that one side of the scraper 10 is in contact with the inner wall of the tank body 1, so that the raw materials adhering to the inner wall of the tank body 1 can be scraped off when the scraper 10 rotates. At the same time, the moving structure 27 moves and pushes the scraper block 26 to move to the top of the partition plate 12, so that the raw materials can be pushed to the moving port, and then moved from the moving port to the inside of the conveying pipe 17 for filtering and leakage, so as to improve the efficiency of raw material leakage and leaching.

[0047] like Figure 8-9 As shown, the adjustment structure 20 includes a dual-axis motor 201, and the output ends on both sides of the dual-axis motor 201 are fixedly connected with connecting rods 202, one end of the connecting rod 202 passes through the movable port and is fixedly connected to the second filter 19, and the top of the dual-axis motor 201 is fixedly connected with a fixing frame 203, and the two ends of the top of the fixing frame 203 are fixedly installed with telescopic columns 204, and the top of the telescopic column 204 is fixedly connected to the partition plate 12.

[0048] By starting the dual-axis motor 201 to drive the connecting rod 202 to rotate, the connecting rod 202 drives the second filter screen 19 to rotate, so that the raw material on the second filter screen 19 is flipped to the top of the first filter screen 18. When the extrusion plate 16 moves downward to extrude the second filter screen 19, the telescopic column 204 is extended to push the fixing frame 203 to drive the second filter plate 11 to move downward. Through the movement and extrusion of the second filter screen 19, the raw material can be fully and comprehensively squeezed. Since the holes on the first filter screen 18 and the second filter screen 19 are smaller than the radius of the raw material, it is convenient to filter it again, thereby improving the effect of solution leaching.

[0049] like Figure 8-10 As shown, the dual-axis motor 201, the telescopic column 204 and the fixed frame 203 are all located between the two conveying pipes 17, the second magnetic block 24 is fixedly connected to the bottom of the connecting rod 202 located inside the movable port, the strip port passes through the bottom end of the conveying pipe 17, and the movable plate 23 is located inside the movable port near the second filter screen 19.

[0050] Since the dual-axis motor 201, the telescopic column 204 and the fixed frame 203 are all located between the two conveying pipes 17, the dual-axis motor 201 can be easily fixed by the telescopic column 204 and the fixed frame 203. When the dual-axis motor 201 drives the connecting rod 202 to rotate, it is convenient to turn over the second filter screens 19 inside the two conveying pipes 17 at the same time, thereby improving efficiency. When the first magnetic block 21 and the second magnetic block 24 facilitate the first filter screen 18 to move up and down in the conveying pipe 17, it can drive the movable plate 23 to move in the strip opening. When the second filter screen 19 moves to the first filter screen 18 and penetrates the bottom end of the conveying pipe 17, the movable plate 23 is located inside the movable opening near the second filter screen 19. When the raw material at the bottom is squeezed, the movable plate 23 moves to the bottom of the conveying pipe 17 through the strip mouth. When the second filter screen 19 moves to its original position, the movable plate 23 moves to the inside of the movable mouth through the strip mouth, thereby blocking the movable mouth to prevent the raw material from falling from the movable mouth into the solution at the bottom of the tank body 1 after being turned over, so that when the raw material is discharged with the solution, the discharge pipe 3 is blocked.

[0051] like Figure 9-10 As shown, a movable groove is provided on the inner wall of the conveying pipe 17 away from the movable port, an electric telescopic rod 28 is fixedly installed inside the movable groove, a slot is provided on the side of the second filter screen 19 close to the movable groove, one end of the electric telescopic rod 28 passes through the inner wall of the conveying pipe 17 and is plugged into the slot, a support plate 29 is provided on one side of the movable groove, the top of the support plate 29 is located at the bottom of the second filter screen 19, a connecting plate 30 is fixedly connected to the top of the support plate 29, the connecting plate 30 is located inside the movable groove, and the top of the connecting plate 30 is fixedly connected to the electric telescopic rod 28.

[0052] The electric telescopic rod 28 is installed through the movable groove, and the electric telescopic rod 28 is plugged into the slot on one side of the second filter screen 19, so that the second filter screen 19 is fixed on the top of the conveying pipe 17. At the same time, the bottom of the filter screen is supported by the support plate 29, so that when the extrusion plate 16 squeezes the raw material on the top of the second filter screen 19, the second filter screen 19 remains stable. When the second filter screen 19 needs to be flipped, the connecting plate 30 is driven to move by the electric telescopic rod 28. When one end of the electric telescopic rod 28 moves to the inside of the movable groove, it is no longer plugged into the slot. The connecting plate 30 drives the support plate 29 to move into the movable groove, and no longer supports the bottom of the second filter screen 19, so that the second filter screen 19 is no longer limited. The second filter screen 19 is driven to flip through the action of the dual-axis motor 201 and the connecting rod 202, which is beneficial to improving the proximity effect of the raw materials.

[0053] like Figure 3-7 As shown, the moving structure 27 includes a second motor 271, a threaded rod 272 is fixedly connected to the conveying end of the second motor 271, the bottom of the threaded rod 272 is rotatably connected to the inner wall of the bottom of the fixed groove, a moving block 273 is threadedly connected to the outer surface of the threaded rod 272, and limiting rods 274 are movably connected at both ends of the moving block 273. Pushing plates 275 are arranged on both sides of the moving block 273, and sliding plates 276 are slidably connected to the bottom ends of the threaded rod 272 and the limiting rod 274. Two fixed rods 277 are fixedly connected to the bottom of the sliding plate 276. One end of the two fixed rods 277 passes through the bottom of the rotating shaft 7 and connects to the scraper block. 26 is fixedly connected to the top, the second motor 271 is fixedly installed on the top of the rotating shaft 7, the pushing plate 275 is fixedly connected to the second movable plate 9 on the side away from the limiting rod 274, the moving block 273 is located between the two pushing plates 275, and is located at the top of the pushing plate 275, the pushing plate 275 and the moving block 273 opposite sides are both inclined surfaces, the pushing plate 275 is located at the top of the sliding plate 276, and the bottom of the sliding plate 276 is fixedly connected with a connecting spring 31, the bottom of the connecting spring 31 is fixedly installed with the inner wall of the bottom of the fixing groove, and the connecting spring 31 is located between the fixing rod 277 and the limiting rod 274.

[0054] The threaded rod 272 is driven to rotate by the second motor 271, so that the moving block 273 moves downward under the action of the limiting rod 274. Since the opposite sides of the pushing plate 275 and the moving block 273 are both inclined surfaces, when the moving block 273 moves downward along the threaded rod 272 between the pushing plates 275, the moving block 273 squeezes the pushing plate 275, so that the pushing plate 275 pushes the second movable plate 9 to drive the scraper 10 to move and fit the inner wall of the tank body 1. At the same time, when the moving block 273 moves to the bottom of the threaded rod 272, the moving block 273 pushes the sliding plate 276 and the fixed rod 277 to move downward, and the connecting spring 31 is compressed so that the bottom of the scraper block 26 fits the top of the partition plate 12. When the soaking is completed and the soaked raw materials are discharged, the rotating shaft 7 is rotated so that the second movable plate 9 drives the scraper 10 to rotate, so that the raw materials adhered to the inner wall of the tank body 1 are scraped off, and the raw materials are pushed into the moving port through the rotation of the scraper block 26, and transported to the inside of the conveying pipe 17 for extrusion and leakage, so as to improve the effect of raw material transportation.

The Chinese medicine spray in the present invention focuses on the impact on the oral microenvironment, and comprehensively considers factors such as microbial composition, immune status, and changes in oral mucosa. Through in-depth research on the regulatory effect of the Chinese medicine spray in the present invention on the oral microenvironment, a more comprehensive and accurate solution can be provided for post-implant rehabilitation treatment.

[0083] 2. Innovation of research methods:

[0084] Combination therapy of antibiotics and antibacterial liquid: Previous studies may have focused on single treatment methods, while this study introduced the combination therapy of antibiotics and the Chinese medicine spray of the present invention. This combination therapy may have a synergistic effect and may have better effects on microcirculation indicators, periodontal indicators, and healing conditions. Compared with previous studies, the efficacy of different treatment methods can be compared.

[0085] Expected social benefits:

[0086] (1) Improving the effect of post-implantation rehabilitation treatment: The Chinese medicine spray of the present invention is a new oral antibacterial treatment method. Its application can effectively prevent post-implantation infection and promote wound healing and rehabilitation. When patients receive post-implantation rehabilitation treatment, they can obtain better treatment effects, reduce the occurrence of infection and complications, and improve their quality of life;

[0087] (2) Reduce the abuse of antibiotics: Traditional oral antibacterial treatment often relies on the use of antibiotics, while the Chinese medicine spray in the present invention is a natural antibacterial treatment method that avoids the abuse of antibiotics. This has a positive significance for reducing the formation of antibiotic resistance. By promoting the application of the Chinese medicine spray in the present invention, the dependence of patients on antibiotics after oral implant surgery can be reduced, and the potential risks caused by the abuse of antibiotics can be reduced;

[0088] (3) Promote the development of oral Chinese medicine treatment: This topic promotes the application and development of Chinese medicine treatment in the field of oral medicine by introducing the Chinese medicine spray of the present invention.

[0089] Working principle: When in use, first weigh the proportion of Panax notoginseng, safflower, Corydalis yanhusuo, Chinese gallnut, clove, Bletilla striata and mint raw materials, then coarsely grind the above raw materials, when the raw materials are ground into coarse powder, open the tank cover 2, pour the ground raw materials into the tank body 1, filter through the filter plate 11 to filter the impurities inside the raw materials, and then put the indigo package into the tank body 1 through the conveying port 6, install the tank cover 2 on the top of the tank body 1, and soak the raw materials. During the soaking process, start the first motor 5 to drive the rotating shaft 7 and the first movable plate 8, the second movable plate 9 and the scraper 10 to rotate, and stir the soaked raw materials. When the second movable plate 9 rotates, it drives the second electric push rod 15 and the squeezing plate 16 to rotate on the top of the partition plate 12 to fully stir the soaked raw materials. When the soaking is completed, the squeezing plate 16 rotates to separate from the moving port, and the sealing plate 14 is driven to move by starting the first electric push rod 13 to expose the moving port, so that the solution and raw materials inside the tank body 1 enter the inside of the conveying pipe 17, and are filtered by the first filter screen 18 and the second filter screen 19. The control valve 4 is controlled to discharge the solution from the discharge pipe 3 for collection. When the raw materials fall on the first filter screen 18 in the conveying pipe 17, the first motor 5 and the rotating shaft 7 are rotated to make the first filter screen 18 and the second filter screen 19 be filtered. The first movable plate 8 and the second movable plate 9 drive the second electric push rod 15 to rotate, so that the extrusion plate 16 moves to the top of the moving port, and then the first electric push rod 13 is started to make the extrusion plate 16 move to the inside of the conveying pipe 17 through the moving port, so that the extrusion plate 16 moves to the top of the second filter plate 11, and the raw materials remaining on the second filter plate 11 are squeezed. After the solution is squeezed out, the connecting rod 202 is driven to rotate by the double-axis motor 201, and the connecting rod 202 rotates the second filter screen 19, so that the first magnetic block 21 is separated from the second magnetic block 24. After the second filter screen 19 is turned over, the first magnetic block 21 connected to the other side of the connecting rod 202 is turned over. The magnetic block 21 and the second magnetic block 24 attract each other. When the residual raw material falls onto the first filter screen 18, the second filter screen 19 is squeezed by the squeezing plate 16. The second filter screen 19 squeezes the first filter screen 18 downward, so that the telescopic rod is extended, and the fixed frame 203 drives the dual-axis motor 201 and the connecting rod 202 to move downward, so that the connecting spring 31 at the bottom of the first magnetic block 21 is compressed, and the sliders 25 on both sides of the movable plate 23 move along the slide groove. When the movable plate 23 moves to the bottom of the movable opening, the second filter screen 19 can squeeze the raw material on the first filter screen 18, so that the raw material can be fully squeezed and easily squeezed out.

[0090] When the raw material leaches and leaks, the second motor 271 drives the threaded rod 272 to rotate, so that the moving block 273 moves downward under the action of the limiting rod 274. Since the push plate 275 and the moving block 273 have inclined surfaces on the opposite sides, when the moving block 273 moves downward along the threaded rod 272 between the push plates 275, the moving block 273 squeezes the push plate 275, so that the push plate 275 pushes the second movable plate 9 to drive the scraper 10 to move and fit the inner wall of the tank body 1. At the same time, when the moving block 273 moves to the threaded rod 274, the moving block 273 moves to the threaded rod 274. When the rod 272 reaches the bottom, the moving block 273 pushes the sliding plate 276 and the fixed rod 277 to move downward, and the connecting spring 31 is compressed, so that the bottom of the scraper block 26 fits with the top of the partition plate 12. When the soaking is completed and the soaked raw materials are discharged, the rotating shaft 7 is rotated to make the second movable plate 9 drive the scraper 10 to rotate, so that the raw materials adhered to the inner wall of the tank body 1 are scraped off, and the raw materials are pushed into the moving port through the rotation of the scraper block 26, and transported to the inside of the conveying pipe 17 for extrusion and leakage, so as to improve the effect of raw material transportation.

[0091] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
