Description

Technical Field

[0002] The microbial limit test of drugs is a method for checking the degree of microbial contamination of non-sterile preparations and their raw materials. It is an important test for controlling and improving the quality of drugs, and is also an important indicator for controlling the quality of hospital preparations. Among them, the microbial colony counting method is a commonly used microbial detection method. The main steps are to dilute the treated sample liquid and oscillate and mix it, then take an appropriate amount of diluent and add it to the solidified culture medium plate, and evenly apply it with a sterile cotton swab to make the sample fully contact with the culture medium, and then culture it. At present, the above operations of this detection method are mainly completed manually.

[0044] The use principle of this embodiment is as follows: if the dilution using the ball cup 12 alone cannot meet the requirements and a higher degree of dilution is required, then when in use, the drug sample to be diluted is added to the dilution tube 57, the lid 2 is covered, and the working parameters of the rotating motor 33 and the water pump 25 are set through the control panel 3. At this time, the ball cup 12 is in a vertical state, the electromagnetic valve 2 62 is closed, the electromagnetic valve 3 65 is turned on, and the water pump 25 is turned on to pump a certain amount of diluent into the channel 5 64 through the channel 1 29, the channel 2 30 and the channel 4 61, so that the diluent is added to the dilution tube 57, and then the rotating motor 33 is turned on to drive the support plate 2 6 and the support plate 1 5 to move back and forth along the width direction of the detection box 1, the support plate 2 6 pushes the horizontal rod 19, and the horizontal rod 19 pushes the piston 1 21 to move. At this time, the electromagnetic valve 1 60 is in an open state, and the piston 1 21 pushes the piston 2 22 to do a meaningless action at this time. When the piston 3 58 and the piston 4 59 are moved, the piston 4 59 pushes the liquid in the dilution tube 57 to move up and down, thereby mixing the diluent and the drug sample liquid; after the mixing is completed, the alarm light 4 is turned on to remind the staff to complete the dilution work. At this time, the support plate 1 5 returns to the original position and waits for the next step; the inspector opens the cover 2, manually transfers a certain amount of liquid in the dilution tube 57 into the ball cup 12, covers the cover 2 again, sets the operation mode of the rotating motor 33 and the water pump 25 through the control panel 3, closes the solenoid valve 3 65 and the solenoid valve 1 60, opens the solenoid valve 2 62, turns on the water pump 25, pumps the diluent from the liquid storage bottle 24 into the ball cup 12, and then turns on the rotating motor 33. At this time, the rotating motor 33 plays the role of mixing the drug sample liquid in the ball cup 12, and the rotating motor 33 drives the support plate 1 5 to move back and forth, thereby driving the carrier 7 to rotate back and forth, thereby mixing the liquid in the ball cup 12;

[0045] After the mixing is completed, the rotating motor 33 drives the support plate 5 to move toward the side away from the U-shaped tube 20, and the ball cup 12 rotates clockwise. At this time, the support plate 26 and the culture dish 18 are close to the side where the ball cup 12 is located. At the same time, the liquid outlet pipe 14 rotates toward the direction of the support plate 5. When the liquid in the ball cup 12 reaches the connection between the liquid outlet pipe 14 and the ball cup 12 as the ball cup 12 rotates, the liquid in the ball cup 12 flows out from the liquid outlet pipe 14. At this time, the culture dish 18 has moved to the bottom of the end of the liquid outlet pipe 14 away from the ball cup 12. At this time, the liquid flowing out of the liquid outlet pipe 14 flows into the culture dish 18. When the liquid flowing into the culture dish 18 reaches the set amount, the rotating motor 33 drives the support plate 5 to move toward the side close to the U-shaped tube 20, and the ball cup 12 is moved straight again;

[0046] Then the rotating motor 33 drives the support plate 5 to move toward the side where the U-shaped tube 20 is located, and then drives the support plate 5 to move toward the side away from the U-shaped tube 20, and so on. During this process, the push rod 23 pushes the gear 16, driving the gear 16 to rotate, thereby pulling the annular slider 46 with the pull rope 48 to rotate, so that the disc 17360° is continuously tilted to achieve the purpose of evenly coating the diluted sample liquid in the culture dish 18 on the surface of the culture medium; after completing this step, open the cover 2, take out the culture dish 18 for culture, and then replace the next group of culture dishes 18, repeat adding the sample liquid to the next group of culture dishes 18 and evenly coating it; the water pump 25 of this embodiment controls the pumping amount of the diluent can be calculated in advance according to the pumping force, time and length and diameter of each channel of the water pump 25, and set it in the control panel 3. This measurement technology is a prior art and can be pre-measured according to the size and specifications of the actual product, so there is no need to set a flow sensor.

[0047] The above is an embodiment of the present invention. The above embodiments and the specific parameters in the embodiments are only for the purpose of clearly describing the invention verification process, and are not intended to limit the patent protection scope of the present invention. The patent protection scope of the present invention is still subject to its claims. Any equivalent structural changes made by using the contents of the description and drawings of the present invention should be included in the protection scope of the present invention.
