Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a drug detection and identification device and identification method.

[0024] Example 1, a typical implementation of this application, such as Figure 1 As shown, a drug detection and identification device and identification method include a base 1, a detection mechanism 2 disposed on the base 1, and an auxiliary mechanism 3 disposed on the detection mechanism 2. The detection mechanism 2 includes a central shaft 24 and a dissolution cup 27. The dissolution cup 27 is disposed on the base 1, and the central shaft 24 is disposed on the base 1. The central shaft 24 is located above the dissolution cup 27, and the bottom end of the central shaft 24 extends to the inner bottom end of the dissolution cup 27. The auxiliary mechanism 3 includes a control box 33 and a sampling tube 315. The control box 33 is installed on the base 1 and is connected to the central shaft 24. The control box 33 extracts the sample from the dissolution cup 27 through the central shaft 24. The sampling tube 315 is installed on the base 1 and the sample extracted by the control box 33 is sent into the sampling tube 315.

[0025] When using this invention: The sampling tube 315 is moved to the bottom of the control box 33, and then water and drugs are put into the dissolution cup 27. The drugs in the dissolution cup 27 are processed by rotating the central shaft 24. Whenever a sample needs to be extracted, some drugs in the dissolution cup 27 are extracted by the control box 33 and sent into the sampling tube 315. The sampling tube 315 is replaced after each sampling, so that the device does not need to be stopped at each sampling point in the detection process, thus improving the processing efficiency of the drug detection and identification device.

[0026] Example 2, as Figures 2-6 As shown, the difference from the above embodiment is that the detection mechanism 2 also includes a housing 21. The housing 21 is fixedly installed on the base 1. Multiple electric telescopic rods 22 are fixedly installed inside the housing 21. The electric telescopic rods 22 are evenly distributed in a straight line. The extension rods of the electric telescopic rods 22 penetrate through the top surface of the housing 21. An equipment box 23 is provided above the housing 21. The equipment box 23 is fixedly connected to the extension rods of the electric telescopic rods 22. The equipment box 23 is located directly above the dissolution cup 27.

[0027] Furthermore, multiple central shafts 24 are rotatably fitted on the equipment box 23. The central shafts 24 are vertically arranged and evenly distributed in a straight line. The central shafts 24 penetrate the equipment box 23. Stirring elements 25 are fixedly installed on the bottom side wall of each central shaft 24. The stirring elements 25 include stirring blades and stirring rods. The stirring blades and stirring rods of the stirring elements 25 are spaced apart on the central shafts 24. A water bath 26 is fixedly installed next to the base 1. The water bath 26 is at the same height as the shell 21. Multiple dissolution cups 27 are installed in the water bath 26. The dissolution cups 27 are evenly distributed in a straight line. The top of each dissolution cup 27 penetrates the top surface of the water bath 26. The top of each dissolution cup 27 is an open end. Each central shaft 24 extends into each dissolution cup 27.

[0028] Furthermore, a first gear 28 is fixedly installed on the central shaft 24. The first gear 28 is located inside the equipment box 23 and is at the same height. Multiple stepper motors 29 are fixedly installed inside the equipment box 23. Each stepper motor 29 is adjacent to a first gear 28. A second gear 210 is fixedly installed on the shaft of each stepper motor 29. The second gear 210 meshes with the first gear 28.

[0029] First, the electric telescopic rod 22 is activated, which lifts the equipment box 23, causing the central shaft 24 to detach from the dissolution cup 27. Then, the drug and water are added to the dissolution cup 27, and water is simultaneously added to and heated in the water bath 26. The water level in the water bath 26 needs to be higher than the liquid level in the dissolution cup 27. Then, the electric telescopic rod 22 lowers the equipment box 23, causing the central shaft 24 to re-enter the dissolution cup 27. The stepper motor 29 is then activated, which drives the second gear 210 to rotate. The second gear 210 drives the first gear 28 to rotate, which in turn drives the central shaft 24 to rotate. The central shaft 24 then drives the stirring element 25 to rotate, allowing the stirring element 25 to process the drug in the dissolution cup 27.

[0030] Example 3, as Figures 7-12 As shown, the difference from the above embodiment is that the auxiliary mechanism 3 also includes a bearing ring 31. A bearing ring 31 is provided at the top of the central shaft 24. A through pipe is opened inside the central shaft 24. The bottom end of the through pipe of the central shaft 24 opens to the bottom end of the central shaft 24, and the top end of the through pipe of the central shaft 24 opens to the top end of the central shaft 24. The outer ring of the bearing ring 31 is connected to the central shaft 24, and the inner ring of the bearing ring 31 is connected to the central shaft 24. Multiple connecting pipes 32 are fixedly installed on the equipment box 23. Each connecting pipe 32 is adjacent to each bearing ring 31. One end of the connecting pipe 32 is connected to the inner ring of the bearing ring 31, and the other end of the connecting pipe 32 passes through the top surface of the equipment box 23. Multiple control boxes 33 are fixedly installed inside the equipment box 23. The other end of each connecting pipe 32 is connected to the top end of each control box 33.

[0031] Furthermore, a detector 34 is fixedly installed at the bottom of each control box 33. The detector 34 is connected to the control box 33 and detects the flow rate of the drug sample. A sampling tube 35 is fixedly installed at the bottom of each detector 34 and is connected to the detector 34. The bottom end of the sampling tube 35 is an open end.

[0032] Furthermore, an inner shell 36 is fixedly installed inside each control box 33. The thickness of the inner shell 36 is the same as the thickness of the inside of the control box 33. Both ends of the inner shell 36 are open. A pump gear 37 is rotatably fitted inside the control box 33. The pump gear 37 includes two gears, an upper gear and an lower gear. The two gears of the pump gear 37 mesh with each other. The overall coverage area of ​​the pump gear 37 is adapted to the internal dimensions of the inner shell 36. A pump motor 38 is fixedly installed on each control box 33. The pump motor 38 is poweredly connected to the pump gear 37.

[0033] Furthermore, a first control ring 39 is rotatably fitted on one side of the control box 33. The first control ring 39 has a ring structure and its bottom end is open. The inner ring of the first control ring 39 is connected to one end of the inner shell 36. A second control ring 310 is rotatably fitted on the other side of the control box 33. The second control ring 310 has a ring structure and its top end is open. The inner ring of the second control ring 310 is connected to the other end of the inner shell 36. The first control ring 39 and the second control ring 310 cannot be connected. Servo motors 311 are fixedly installed on both sides of the control box 33. The servo motors 311 are poweredly connected to the first control ring 39 and the second control ring 310, respectively.

[0034] Furthermore, both the first control ring 39 and the second control ring 310 have toothed grooves on their sides, and the servo motor 311 has a gear on its shaft. The servo motor 311 transmits power to the first control ring 39 and the second control ring 310 using a gear ring. The position where the gear passes through the control box 33 is sealed and blocked by the first control ring 39 and the second control ring 310 themselves, so that the inside and outside of the control box 33 are not connected at this point.

[0035] Furthermore, a water tank 312 is fixedly installed on the top of the equipment box 23, and an interface 313 is fixedly installed on the side of the control box 33. The interface 313 is connected to the control box 33. When the interface 313 is adjacent to the open end of the first control ring 39, the interface 313 is connected to the first control ring 39. The interface 313 is connected to the water tank 312. A pipe rack 314 is provided inside the equipment box 23. The pipe rack 314 penetrates the equipment box 23 and is located below the sampling pipe 35. Multiple sampling tubes 315 are provided on the sampling pipe 35, and each sampling tube 315 is located directly below its respective sampling pipe 35.

[0036] Furthermore, the water tank 312 and the interface 313 are connected by a soft water pipe.

[0037] When sampling is required, the pump motor 38 is started, driving the pump gear 37 to operate. The pump gear 37 creates a suction force on the inner shell 36 from one end to the other. Simultaneously, the servo motor 311 is started, driving the open end of the first control ring 39 towards the top and the open end of the second control ring 310 towards the bottom. Due to the generated suction force, the central shaft 24's through-tube draws the drug sample from the dissolution cup 27. The drug sample first passes through the central shaft 24's through-tube into the connecting tube 32, and then enters the control box 33 from the connecting tube 32. At this time, due to the second... The blocking effect of the control ring 310 and the orientation of the open end of the first control ring 39 cause the drug sample to flow into the inner ring of the first control ring 39. Then, the drug sample flows from the first control ring 39 to one end of the inner shell 36, and then from the other end of the inner shell 36 into the second control ring 310. Then, the drug sample flows from the second control ring 310 into the detector 34, and then from the detector 34 into the sampling tube 35. Finally, the drug sample falls from the sampling tube 35 into the sampling tube 315. After sampling, the sampling tube 315 is taken out using the tube rack 314, and then a new sampling tube 315 is put in and put back in place. After the overall inspection and processing, the open end of the first control ring 39 can be turned to face the interface 313, and the open end of the second control ring 310 can be turned to face the top. The pump gear 37 can be used to draw water from the water tank 312 into the interface 313. The water then flows from the interface 313 into the first control ring 39, from the first control ring 39 into the inner shell 36, from the inner shell 36 into the second control ring 310, from the second control ring 310 into the connecting pipe 32, from the connecting pipe 32 into the through pipe of the central shaft 24, and finally the water is discharged from the through pipe of the central shaft 24 into the dissolution cup 27, so that the auxiliary mechanism 3 can be cleaned with water.

[0038] Working principle of the invention: The sampling tube 315 is moved to the bottom of the control box 33, and then water and drugs are put into the dissolution cup 27. The drugs in the dissolution cup 27 are processed by the rotation of the central shaft 24. Whenever a sample needs to be extracted, some drugs in the dissolution cup 27 are extracted by the control box 33 and sent into the sampling tube 315. The sampling tube 315 is replaced after each sampling, so that the device does not need to be stopped at each sampling point in the detection process, thus improving the processing efficiency of the drug detection and identification device. First, the electric telescopic rod 22 is activated, which lifts the equipment box 23, causing the equipment box 23 and the central shaft 24 to detach from the dissolution cup 27. Then, drugs and water are added to the dissolution cup 27, and water is simultaneously added to the water bath 26 and heated. The water level in the water bath 26 needs to be higher than the liquid level in the dissolution cup 27. Then, the electric telescopic rod 22 lowers the equipment box 23, causing the central shaft 24 to re-enter the dissolution cup 27. The stepper motor 29 is then activated, which drives the second gear 210 to rotate. The second gear 210 drives the first gear 28 to rotate, which drives the central shaft 24 to rotate. The central shaft 24 drives the stirring element 25 to rotate, so that the stirring element 25 processes the drugs in the dissolution cup 27. When sampling is required, the pump motor 38 is started, driving the pump gear 37 to operate. The pump gear 37 creates a suction force from one end to the other in the inner shell 36. Simultaneously, the servo motor 311 is started, driving the open end of the first control ring 39 towards the top and the open end of the second control ring 310 towards the bottom. Due to the generated suction force, the through-tube of the central shaft 24 draws the drug sample from the dissolution cup 27. The drug sample first passes through the through-tube of the central shaft 24 into the connecting tube 32, and then enters the control box 33 from the connecting tube 32. At this time, due to the second control... The obstruction of the control ring 310 and the orientation of the open end of the first control ring 39 allow the drug sample to flow into the inner ring of the first control ring 39. Then, the drug sample flows from the first control ring 39 to one end of the inner shell 36, and then from the other end of the inner shell 36 into the second control ring 310. Then, the drug sample flows from the second control ring 310 into the detector 34, and then from the detector 34 into the sampling tube 35. Finally, the drug sample falls from the sampling tube 35 into the sampling tube 315. After sampling, the sampling tube 315 is removed using the tube rack 314, and then a new sampling tube 315 is placed back in place. After the overall inspection and processing, the open end of the first control ring 39 can be turned to face the interface 313, and the open end of the second control ring 310 can be turned to face the top. The pump gear 37 can be used to draw water from the water tank 312 into the interface 313. The water then flows from the interface 313 into the first control ring 39, from the first control ring 39 into the inner shell 36, from the inner shell 36 into the second control ring 310, from the second control ring 310 into the connecting pipe 32, from the connecting pipe 32 into the through pipe of the central shaft 24, and finally the water is discharged from the through pipe of the central shaft 24 into the dissolution cup 27, so that the auxiliary mechanism 3 can be cleaned with water.

[0039] An identification method using the aforementioned drug detection and identification device includes the following steps: S1: Move the sampling tube 315 to the bottom of the control box 33, and then put water and medicine into the dissolution cup 27; S2: The drug in the dissolution vessel 27 is processed by rotating the central shaft 24; S3: Whenever a sample needs to be taken, the control box 33 is used to extract some drug from the dissolution cup 27 and send it into the sampling tube 315. The sampling tube 315 is replaced after each sampling.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
