Description

Technical Field

[0001] The present invention relates to the technical field of drug detection, in particular to a method and device for microscopic photography of Chinese herbal medicine slices and a portable identification device. Background Art

[0002] The quality of Chinese herbal medicine slices directly affects clinical efficacy and patient safety. In the production and application of Chinese herbal medicine slices, accurate identification of the quality and authenticity of the slices is of vital importance. Due to the wide variety of Chinese herbal medicine slices and large differences in quality, the traditional method of relying on professional technicians to identify through visual and microscopic observation still has problems such as low identification efficiency, poor accuracy, and strong subjectivity in operation, which makes it difficult to meet the needs of efficient and standardized control and management of modern production. Microscopic identification technology can accurately identify the source and type of Chinese herbal medicine slices by analyzing the microstructural characteristics of the slices. However, the existing microscopic identification methods still face problems such as complex operation, low degree of automation, low degree of informatization, and large restrictions on usage scenarios, which makes it difficult to meet the needs of large-scale production and rapid testing.

[0003] A Chinese invention patent (publication number: CN117491358B, publication date: March 22, 2024) discloses a microscopically observed Chinese medicinal material identification device and method. The device comprises an identification platform with a protective scanning mechanism on its top; a sample loading recess formed in the top of the identification platform; and a sample loading mechanism movably extending through the inner wall of one side of the sample loading recess. This invention controls the rotation of a screw, which, through a threaded connection between the screw and the slider, drives a motorized turntable for horizontal movement. The turntable then drives the microscopic identification mechanism to rotate above the Chinese medicinal material sample. A third motorized slide then drives the microscopic identification mechanism downward, allowing the sample to be sampled for microscopic examination. Accurate identification of the Chinese medicinal material is achieved through microscopic observation of the sample's epidermis, hypodermis, and other tissue structures. The sampling process does not affect the planting and growth of the sample, thus improving the effectiveness of the identification device. However, the device is aimed at the identification of Chinese medicinal materials, and the device is not portable enough to meet the needs of rapid identification of Chinese medicinal materials in the wild, on-site and other scenarios.

A shaft is fixedly connected to the crushing box, one end of which is coaxially fixedly connected to gear 1, which can mesh with a sector-shaped geared disc. A screen drum is fixedly connected to the crushing box, with a first crushing bar fixed to the inner wall of the screen drum. A second crushing bar is fixed to the outer wall of the shaft, which is located inside the screen drum. The bottom of the crushing box is fixed and connected to a discharge pipe. A feed hopper is fixed to the side wall of the crushing box and connected to the inner side of the screen drum.

[0024] like Figures 1-13 The present invention schematically illustrates a portable device for microscopic identification of Chinese herbal medicine slices. The device comprises a chassis 11 and four functional units integrated within the chassis 11: a crushing and screening unit, a kinetic energy and mass transfer unit, a spraying and imaging unit, and a control and analysis unit. The combination of the crushing and screening unit and the kinetic energy and mass transfer unit constitutes a Chinese herbal medicine slice dyeing device provided by the present invention. In this embodiment, each unit is arranged on the bottom plate inside the chassis 11 and is connected and interconnected by a hard pipe 12, a flexible pipe 13, and a cable 14, thereby achieving material transportation and signal transmission.

[0025] like Figure 1 、 Figure 2 、 Figure 13 As shown, the chassis 11 is a rounded rectangular shape with a regular quadrilateral shape. The size and shape design of the chassis 11 enable it to be adapted to the shell of a standard suitcase, meeting the requirements of easy carrying and storage, and adapting to various usage scenarios, such as on-site work, outdoor operations, etc.

[0026] like Figure 1-Figure 3 、 Figure 8 As shown, the top cover of the chassis 11 is equipped with a sliding compartment cover 111 and a folding cover 112. Under the compartment cover is the crushing and screening unit. The folding cover 112 integrates the touch screen 75 of the display mechanism. The front panel of the chassis 11 is equipped with a glass slide compartment door for the feed carrier mechanism and a switch 10 for the feed carrier mechanism. The back panel of the chassis 11 is equipped with a grille 113, a chassis cover 114, and a power supply interface 17 that passes through the back panel from the inside. The grille 113 is used for active air intake and heat dissipation, which can facilitate the replenishment or replacement of fluid media. The right side panel of the chassis 11 is equipped with a peripheral interface 16 that penetrates the right side panel to facilitate system updates and data transmission.

[0027] like Figure 3 、 Figure 4 、 Figure 7As shown, the crushing and screening unit includes a grinding chamber 21, a plurality of screening chambers 22, and a gas-solid mixing chamber 23 which are sequentially arranged and connected from top to bottom.

[0028] The grinding chamber 21 includes a chamber body, an electric drive module 27, a cutting blade 28, and a transmission mechanism 29 mounted thereon. A material valve 210 is located at the bottom of the chamber, and a chamber sealing cover 26 is located at the top. The electric drive module 27 is mounted on the outside of the chamber and is equipped with a drive motor 271. The cutting blade 28 is located on the inside of the chamber and penetrates the chamber and is mounted on the electric drive module 27. The electric drive module 27 drives the cutting blade 28 to crush the Chinese medicinal pieces within the grinding chamber 21. The transmission mechanism 29 is mounted on the electric drive module 27 and connected to the material valve 210, allowing it to adjust the opening and closing of the material valve 210 at the bottom of the grinding chamber 21.

[0029] Furthermore, the grinding chamber 21 is also provided with a flexible pipe 13, which extends from the inside of the cavity to the outside and is connected to a two-way solenoid valve 32. The two-way solenoid valve 32 is also connected to the first micro-scroll compressor 31. The first micro-scroll compressor 31 can generate a stable airflow of a certain pressure, and the two-way solenoid valve 32 can adjust the direction and flow rate of the airflow. A one-way air guide valve 211 is also provided on the flexible pipe 13 outside the grinding chamber 21. The connection of the above pipes can provide a stable airflow for the crushing and screening units. On the one hand, the airflow can participate in the process of crushing the Chinese medicinal materials, which is conducive to the Chinese medicinal materials being fully cut by the cutting blade 28; on the other hand, the airflow can propel the crushed particles 20 of the Chinese medicinal materials to be screened, provide stable power for the mass transfer process, and also clean the cavity to a certain extent.

[0030] Several screening chambers 22 are stacked up and down to form a screening mechanism, which can be screwed by threads; the screening chamber 22 at the top is connected to the grinding chamber 21, and the screening chamber 22 at the bottom is connected to the gas-solid mixing chamber 23, and each screening chamber 22 is provided with a screening net 221, 222 of different specifications fixed therein. The crushed particles 20 of the Chinese herbal medicine slices will enter the gas-solid mixing chamber 23 after particle size separation through the screening nets 221, 222.

[0031] Briefly, the crushing and screening unit consists of a grinding chamber 21, a screening chamber 22, and a gas-solid mixing chamber 23, all connected along the center. The entire unit is cylindrical. A bracket 24 is provided on the side of the crushing and screening unit, with a pulley at the end. A slide rail 25 is provided on the bottom plate of the chassis 11. The bracket 24 is compatible with and positioned in a corresponding manner to the slide rail 25. The bracket 24 is moved and fixed along the phase of the slide rail 25, enabling the unit to be erected vertically or placed horizontally.

[0032] The working mode of the crushing and screening unit is as follows: the Chinese herbal medicine slices are put into the grinding chamber 21. Figure 4As shown, the material valve 210 is in a closed state, the driving motor 271 of the electric drive module 27 is started, and the cutting blade 28 is driven by the electric drive module 27 to cut and crush the Chinese herbal medicine pieces to obtain the Chinese herbal medicine pieces crushed particles 20. In this process, the introduction of air flow can improve the crushing rate; the material valve 210 is under the control of the transmission mechanism 29, as shown in FIG. Figure 4 After the state is changed from closed to open, the crushed particles 20 of the Chinese herbal medicine enter the screening chamber 22 and are separated by particle size through multiple layers of screens 221 and 222. In this process, the introduction of airflow can promote screening, provide stable power for the mass transfer process and clean the cavity to a certain extent; finally, under the action of gravity and airflow, the crushed particles 20 of the Chinese herbal medicine enter the gas-solid mixing chamber 23.

[0033] like Figure 5-Figure 7 As shown, the kinetic energy and mass transfer unit includes a first micro-scroll compressor 31, a two-way solenoid valve 32, a color developer storage tank 34, a venturi ejector 36, a tubular static mixer 37, and a medicinal material suspension storage tank 38, which are connected in sequence through pipelines, wherein the venturi ejector 36 is also connected to the gas-solid mixing chamber 23, and a branch pipeline one-way solenoid valve 331 and a loop pipeline one-way solenoid valve 332 are also provided between the color developer storage tank 34 and the venturi ejector 36.

[0034] The developer liquid storage tank 34 has a sealing cover 341 at the top, with an air pressure valve 3411 installed on the sealing cover. An air inlet and two liquid outlets are located on the side of the tank body. The air inlet and the two liquid outlets are not on the same side, and the two liquid outlets are at different elevations. The air inlet is connected to a two-way solenoid valve 32 via a pipe. The two liquid outlets form a pipe loop and branch lines via pipes and one-way solenoid valves 331 and 332. Specifically, a first branch pipe and a second branch pipe are provided on the pipeline between the developer liquid storage tank 34 and the venturi ejector 36. The first branch pipe is connected to the venturi ejector 36 and the lower-elevation liquid outlet, respectively, while the second branch pipe is connected to the higher-elevation liquid outlet of the developer liquid storage tank 34 to form a loop.

An ultrasonic vibrator 39 is mounted on the top of the medicinal material suspension storage tank 38, passing through the tank body and into the tank to further homogenize the suspension.

[0037] The kinetic energy and mass transfer unit works as follows: the first micro-scroll compressor 31 operates to generate a stable airflow of a certain pressure, which is injected into the color developer storage tank 34 through the two-way solenoid valve 32 to adjust the airflow direction and flow rate, and the color-developing solution in the color developer storage tank 34 is pressed into the pipeline. During the material transmission process, the loop pipeline one-way solenoid valve 332 is in a closed state, and the branch pipeline one-way solenoid valve 331 is in an open state, thereby pushing the color developer solution into the Venturi ejector 36, and mixing it with the crushed particles of Chinese herbal medicine 20 ejected from the gas-solid mixing chamber 23 to obtain a suspension. The suspension is rushed into the tubular static mixer 37 for further mixing, and then flows into the medicinal material suspension storage tank 38, and is vibrated and homogenized by the ultrasonic vibrator 39 to enhance the mixing uniformity, and then flows to the pressure regulating valve 43.

The dual-fluid nozzle 44 can be positioned below the pressure regulating valve 43.

[0040] The spraying unit works as follows: the second micro-scroll compressor 41 operates to generate a stable airflow of a certain pressure, which is injected into the air tank 42 for collection and controlled by the pressure regulating valve 43; when the suspension in the medicinal material suspension storage tank 38 flows into the pressure regulating valve 43, the airflow in the air tank 42 evenly sprays the suspension onto the disc-shaped slide 50 directly below, and then the pressure regulating valve 43 is closed.

First, the slide compartment door switch 10 is opened, and the feed motor 52 drives the push rod 522, allowing the glass tray holder 51 to exit the compartment under the guidance of the guide pulley 521. After the glass tray holder 51 exits the compartment, the disc-shaped slide 50 is placed on the positioning ring 533 through the central rotating shaft 531. The slide compartment door switch 10 is then pressed, and the glass tray holder 51 drives the fixed disc-shaped slide 50 into the compartment. After the dual-fluid nozzle 44 evenly sprays the test suspension onto the surface of the disc-shaped slide 50, the spindle motor 53, in conjunction with the servo control system, drives the disc-shaped slide 50 in spindle rotation. First, according to the detection needs, the electric heating module 56 supplies power to the electric heating plate 57 to generate heat, thereby temperature-controlled heating of the disc-shaped slide 50. Then, the tracking motor 63 drives the phase guide rod 62 to move the camera module 61 to above the LED light group 54 controlled by the light control module 55 and adjust it to a suitable detection height and radial position.

[0049] like Figure 9 、 Figure 11 As shown, during microscopic inspection, the spindle motor 53 drives the disc-shaped glass slide 50 to rotate. Depending on the inspection requirements, the camera turret 64 can be rotated to call up a microscope camera 651 with different magnifications or functions. After the image focal length is determined, a circular scan or dot-matrix scan is performed on the microscopic structure of the crushed Chinese herbal medicine particles 20 on the entire disc-shaped glass slide 50 as needed, and a captured image 83 is obtained. During circular scanning, after each circular scan cycle image 811 is captured, the tracking motor 63 and phase guide rod 62 drive the camera module 61 to move radially to the next circular track 81. During dot-matrix scanning, the camera module 61 randomly captures dot-matrix scan sectors 82 or site images 821 within the inspection circular track 81.

[0050] For example, Figure 6 、 Figure 7 As shown, the control and analysis unit includes a control mainboard 71 , a power supply mechanism, and a touch display screen 75 .

[0051] The control board 71 contains the central processing unit (CPU), graphics processing unit (GPU), random access memory (RAM), hard drive (HDD), communication module, Beidou module, and peripheral interface 16 required for data transmission, storage, and analysis. Peripheral interface 16, which penetrates the right side panel of the chassis 11 and is located outside the chassis 11, supports high-speed data transmission and high-definition video output. It can connect to external hardware devices such as storage devices, printers, and displays, facilitating system updates and data transmission.

[0052] The power supply mechanism includes a power management board 72 and an internal battery 73. The power management board 72 is equipped with a power supply interface 17, which supports both external power and battery power. A power indicator light 19 indicates the power supply mode through different colored lights. The power management board 72 automatically switches the power input mode, prioritizing external power. When the external power source is disconnected, it automatically switches to battery power. It also provides overvoltage and overcurrent protection to ensure the safety of the external power source, and manages the battery charge through display prompts. The power management board 72 also manages the charging of the internal battery 73 and monitors the battery status to ensure safe charging.

[0053] The control main board 71 and the power management board 72 are both disposed in a main board protective cover 74 to provide physical protection and electromagnetic shielding.

[0054] The touch screen display 75 is arranged on the foldable cover 112 outside the chassis 11.

[0055] The above-mentioned microscopic identification method for Chinese herbal medicine slices using a portable device for Chinese herbal medicine slices is carried out in the following specific steps: 1) Pulverization and screening of Chinese herbal medicine samples: The Chinese herbal medicine samples are placed in the grinding chamber 21, and the drive motor 271 of the electric drive module 27 is started. The electric drive module 27 drives the cutting blade 28 to effectively pulverize the Chinese herbal medicine slices. During the pulverization process, the first micro-scroll compressor 31 timely generates airflow and introduces it into the grinding chamber 21, so that the Chinese herbal medicine slice particles in the chamber are fully in contact with the cutting blade 28. After the grinding is completed, the electric drive module 27 drives the material valve 210 at the bottom of the grinding chamber 21 to open and close through the transmission mechanism 29, so that the crushed particles 20 of the Chinese herbal medicine slices fall fully into the screening chamber 22 under the action of gravity and airflow. After passing through the screening meshes 221 and 222 with different aperture specifications, they fall into the gas-solid mixing chamber 23 with a gradually narrowing cavity and are fully mixed with the vortex airflow. 2) TCM decoction piece sample transmission and dyeing treatment: The crushed TCM decoction piece particles 20 in the gas-solid mixing chamber 23 are finally transported to the venturi ejector 36. The first micro-scroll compressor 31 transports the color-developing solution in the color developer reservoir 34 into the venturi ejector 36. The color-developing solution can be chloral hydrate. The color-developing solution is mixed with the airflow containing the crushed TCM decoction piece particles 20 and flows into the tubular static mixer 37 for further mixing. The mixture is then transported to the medicinal material suspension storage tank 38 and vibrated and fully mixed by the ultrasonic vibrator 39. Finally, under the action of the pressure regulating valve 43, the TCM decoction piece particle suspension is evenly sprayed from the dual-fluid nozzle 44 onto the disc-shaped slide 50. 3) Loading and microscopic inspection of Chinese herbal medicine samples: Before microscopic inspection, the disc-shaped glass slide 50 is passed through the central rotating shaft 531 and placed on the positioning ring 533 in the glass plate holder 51, and then sent to the bottom of the dual-fluid nozzle 44; after the suspension of Chinese herbal medicine particles is evenly sprayed onto the disc-shaped glass slide 50, the spindle motor 53 drives the disc-shaped glass slide 50 to rotate, and the electric heating plate 57 heats the disc-shaped glass slide 50; the camera module 61 is moved to an appropriate fixed focus height by the phase guide rod 62 according to the inspection requirements, and the LED light group 54 below the disc-shaped glass slide 50 is adjusted to an appropriate light flux; Figure 11 As shown, during microscopic inspection, the disc-shaped slide 50 rotates and the microscope group 65 moves linearly, and the microscopic structure of the Chinese herbal medicine sample powder in the entire disc-shaped slide 50 is subjected to a circular scan 81 or a dot-matrix scan 82 as needed, and an image 83 is captured; 4) Data analysis and processing of Chinese herbal medicine slice samples: The image data of the powder microstructure of the Chinese herbal medicine slice samples is transmitted to the control board 71 of the integrated automatic recognition and statistical system of graphic samples. The deep learning algorithm is used to realize the efficient and accurate recognition of the input microstructure 84 graphic sample content of the Chinese herbal medicine slices, and the corresponding feature analysis and statistical analysis report 85 is automatically generated. The screen display interface of the analysis results is as follows: Figure 12 、 Figure 13 As shown; each detection data can be uploaded to the cloud database synchronously for recognition algorithm upgrade and large model training; the microstructure 84 of the Chinese herbal medicine slices and the real-time analysis results are synchronously presented on the touch screen 75, and the relevant results can be transmitted to the external storage device via the peripheral interface 16. The system and local database upgrades can also be achieved through the peripheral interface 16.
