Description

Technical Field

[0001] This utility model relates to the field of microbial detection, specifically a rapid detection device for pharmaceutical microorganisms. Background Technology

[0002] A rapid detection device for pharmaceutical microorganisms is a device for efficiently and conveniently detecting the presence and quantity of microorganisms in pharmaceuticals. Its core objective is to shorten the traditional detection cycle and improve detection efficiency. It consists of sample processing and reaction components and signal detection and control components, forming an instrument with high detection efficiency and high accuracy.

[0003] During use, the microbial detection device has the problem of failing to eliminate a large number of miscellaneous bacteria. This is mainly because a large number of miscellaneous bacteria are introduced when the petri dish is placed, and the device cannot eliminate these bacteria on its own. Furthermore, only one petri dish can be tested at a time, and more miscellaneous bacteria are introduced when the dish is replaced. In addition, the petri dish cannot be rotated or shaken to ensure that the microorganisms inside are evenly distributed, which affects the test results. Utility Model Content

[0004] The purpose of this invention is to provide a rapid detection device for pharmaceutical microorganisms to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid detection device for pharmaceutical microorganisms, comprising a detection chamber, a chassis fixedly installed at the bottom of the detection chamber, a servo motor fixedly installed in the middle of the chassis, a rotating rod fixedly installed at the output end of the servo motor, a turntable fixedly installed at the top of the rotating rod, placement slots formed around the turntable, multiple sets of steel balls rotatably installed inside the placement slots, a protective ring rotatably installed on the outer wall of the placement slots, a clamp provided at the top of the protective ring, a detector fixedly installed at the top of the detection chamber, and multiple sets of ultraviolet lamps fixedly installed at the bottom of the detector.

[0006] Preferably, a servo motor is fixedly installed on the rear side of the chassis, a first magnet is fixedly installed on the output end of the servo motor, a grooved disk is fixedly installed on the outer rear wall of the chassis, a rotating shaft is rotatably installed in the middle of the grooved disk, a second magnet is fixedly installed at the bottom end of the rotating shaft, and a detection probe is fixedly installed in the middle of the rear side of the detector.

[0007] Preferably, a display screen is fixedly installed on the upper rear side of the testing box, and a controller is fixedly installed on the lower rear side of the testing box.

[0008] Preferably, a base is fixedly installed on both the left and right sides of the bottom of the testing box, and a door is rotatably installed on the front side of the testing box.

[0009] Preferably, the detector has a detection instrument inside, and a lamp slot is provided at the bottom of the detector, with the ultraviolet lamp placed inside the lamp slot.

[0010] Preferably, the bottom rear side of the detector has a groove, the detection probe is disposed in the groove, and the groove plate corresponds to the position of the groove.

[0011] Preferably, the protective ring is rotatably connected to the steel ball.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the clamps fix the culture dishes to prevent them from shifting off the center of the inspection during rotation, and multiple groups of culture dishes can be tested at the same time, which is convenient for conducting control experiments and achieves a convenient and fast effect. It also avoids the problem of bringing more bacteria into the instrument due to the need to pick up and drop the dishes multiple times for a single test. At the same time, the sterilization by irradiation with ultraviolet lamp before testing can also greatly eliminate the influence of bacteria on the test. The magnetic rotation structure used inside greatly isolates the bacteria remaining at the friction point of the motor rotor rotation. Attached Figure Description

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example 1, referring to Figures 1 to 5 This is the first embodiment of the present invention, which provides a rapid detection device for pharmaceutical microorganisms. It includes a detection chamber 1, a base 9 fixedly installed at the bottom of the chamber 1, a servo motor 10 fixedly installed in the middle of the base 9, a rotating rod 11 fixedly installed at the output end of the servo motor 10, and a turntable 12 fixedly installed at the top of the rotating rod 11. The turntable 9 and the rotating rod 11 are detachable for easy disinfection and cleaning. Placement slots are provided around the turntable 12, and culture dishes are placed in these slots. Multiple sets of steel balls 13 are rotatably installed inside the placement slots. A protective ring 14 is rotatably installed on the outer wall of the placement slots, protecting the culture dishes. Simultaneously, the culture dishes can rotate within the placement slots with the cooperation of the steel balls 13. A clamp 15 is provided at the top of the protective ring 14 to fix the culture dishes. A detector 6 is fixedly installed at the top of the chamber 1, and multiple sets of ultraviolet lamps 7, which are low-pressure mercury lamps, are fixedly installed at the bottom of the detector 6.

[0023] Specifically, a servo motor 16 is fixedly installed on the rear side of the chassis 9, and a first magnet 17 is fixedly installed on the output end of the servo motor 16. A grooved plate 18 is fixedly installed on the outer rear wall of the chassis 9. The grooved plate 18 has a downward groove in the center, and the four sides of the grooved plate 18 are sealed with the chassis 9. A rotating shaft 19 is rotatably installed in the middle of the grooved plate 18. The rotating shaft 19 is isolated from the chassis through the grooved plate 18. A second magnet 20 is fixedly installed at the bottom end of the rotating shaft 19. A detection probe 8 is fixedly installed in the middle of the rear side of the detector 6. The detection probe is the core component for realizing rapid detection of microorganisms. Through physical, chemical or biological signal conversion, the presence or activity of microorganisms is converted into quantifiable electrical signals, light signals, etc.

[0024] Furthermore, a display screen 2 is fixedly installed on the upper rear side of the testing box 1, and a controller 3 is fixedly installed on the lower rear side of the testing box 1. The testing results are displayed on the display screen 2, and the controller controls the internal components.

[0025] The bottom left and right sides of the test box 1 are fixedly installed with bases 4, and the front side of the test box 1 is rotatably installed with a door 5. The door 5 and the test box 1 are sealed together.

[0026] Preferably, the detector 6 has a detection instrument inside, a lamp slot is opened at the bottom of the detector 6, an ultraviolet lamp 7 is set in the lamp slot, a groove is opened at the rear bottom of the detector 6, a detection probe 8 is set in the groove, the groove plate 18 corresponds to the groove position, and the protective ring 14 is rotatably connected to the steel ball 13.

[0027] In use, open the door 5 and place the culture dish inside the protective ring 14. The culture dish is fixed in place by the clamp 15. Multiple culture dishes can be placed inside the protective ring 14 at the same time. After placement, close the door 5 and start the servo motor 10. Its output end drives the turntable 12 on the rotating rod 11 to rotate. The rotation of the turntable 12 causes the culture dish to rotate in a circle. During rotation, it is irradiated by the ultraviolet lamp 7 below the detector 6 and sterilized. After irradiation, rotate the culture dish to be tested to be directly below the inspection probe 8. At this time, start the servo motor 16. Its output end drives the first magnet 17 to rotate. The first magnet 17 drives the rotating shaft 19, which is equipped with the second magnet 20, to rotate through magnetic force. The friction above the rotating shaft 19 drives the culture dish to rotate slowly, making the culture dish more uniform during testing.

[0028] In summary, the clamp 15 fixes the petri dish, preventing it from shifting off-center during rotation. It also allows for the testing of multiple petri dishes, facilitating control experiments and achieving a convenient and quick result. This avoids the problem of multiple handling of individual tests, which can introduce more bacteria into the instrument. Furthermore, sterilization by irradiation with ultraviolet lamp 7 before testing can greatly eliminate the influence of bacteria on the test. The internal magnetic rotation structure greatly isolates bacteria remaining at the friction points of the motor rotor.

[0029] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
