Description

Technical Field

[0001] This utility model relates to the field of microbial collection instruments, specifically a quantitative device for microbial collection instruments. Background Technology

[0002] A microbial collector, also known as a microbial culture device or sterility testing device, is a specialized piece of equipment used under sterile conditions for microbial limit testing and sterility testing of pharmaceuticals, biological products, etc. It uses a filtration system to trap microorganisms in the sample on the filter membrane inside the filter tank, and then incubates them to detect the presence and quantity of microorganisms in the sample. This equipment is widely used in the pharmaceutical industry, clinical medicine, food safety and other fields.

[0003] When a sample enters the filter tank, it passes through the filter membrane to filter microorganisms and impurities. The traditional method of rinsing the filter membrane in the filter tank is to manually pour the cleaning solution directly into the filter tank to rinse the filter membrane. The cleaning solution dissolves the impurities and leaves the microorganisms. However, it is difficult to ensure that the amount of cleaning solution used is consistent when manually pouring it. If too little cleaning solution is used, the filter membrane will not be rinsed sufficiently, which will affect the test results. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a quantitative device for a microbial collection instrument. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A quantitative device for a microbial collector includes a microbial collector body 1, a filter tank 2 disposed on the surface of the microbial collector body 1, and a quantitative cleaning mechanism 3 disposed on one side of the microbial collector body 1.

[0025] The quantitative cleaning mechanism 3 includes a liquid storage tank 310, which is fixedly connected to one side of the bacteria collector body 1. A mounting box 301 is installed on the top of the liquid storage tank 310, and a motor 302 is installed on the top of the liquid storage tank 310. A rotating rod 303 is rotatably connected to the inner wall of the mounting box 301, with one end of the rotating rod 303 penetrating through the inner wall of the mounting box 301. One end of the rotating rod 303 is fixedly connected to the output end of the motor 302. Three support frames 305 are fixedly connected to the surface of the rotating rod 303, and rollers 306 are rotatably connected to the inner walls of each of the three support frames 305. A flexible hose 304 is installed on the inner wall of the mounting box 301, with both ends of the flexible hose 304 penetrating through the inner wall of the mounting box 301. One end of the hose 304 extends through the inner wall of the storage tank 310, and the other end of the hose 304 is fixedly connected to a corrugated telescopic tube 307. One end of the corrugated telescopic tube 307 is fixedly connected to a diversion tube 308, and a nozzle 309 is fixedly connected to the surface of the diversion tube 308. The nozzle 309 works in conjunction with the filter tank 2. By setting a quantitative cleaning mechanism 3, the motor 302 drives the roller 306 to squeeze the hose 304, controlling the extraction volume and transmission rate of the cleaning liquid, ensuring the accuracy of the cleaning liquid dosage. The position of the nozzle 309 is adjusted by using the corrugated telescopic tube 307 so that it can be flexibly inserted into the filter tank 2, ensuring that the cleaning liquid can evenly cover the entire filter membrane surface. This not only ensures the quantitative nature of the rinsing process but also improves the rinsing efficiency and quality.

[0026] Reference Figure 1 The top of the liquid storage tank 310 is fixedly connected to a water inlet pipe 4, and the top of the water inlet pipe 4 is threadedly connected to a sealing cap 5. By setting the water inlet pipe 4, the cleaning liquid can be safely and efficiently injected into the liquid storage tank 310. The sealing cap 5 is used to ensure the sealing of the liquid storage tank 310 and prevent the cleaning liquid from leaking.

[0027] Reference Figure 1 A drain pipe 7 is fixedly connected to one side of the liquid storage tank 310. A valve 8 is rotatably connected to the inner wall of the drain pipe 7. By setting the drain pipe 7 and the valve 8, it is convenient to clean the liquid storage tank 310 with clean water after the cleaning liquid is used up, and to facilitate the drainage of clean water.

[0028] Reference Figure 2The top of the liquid storage tank 310 is fixedly connected to the first support block 9 and the second support block 10 respectively. The bottom of the motor 302 is fixedly connected to the top of the first support block 9, and the bottom of the mounting box 301 is fixedly connected to the top of the second support block 10. One end of the hose 304 passes through the inner wall of the second support block 10. By setting the first support block 9 and the second support block 10, the motor 302 and the mounting box 301 can be supported and fixed to prevent displacement and ensure the stability of the motor 302 and the mounting box 301.

[0029] Reference Figure 2 The inner wall of the mounting box 301 is fixedly connected to a bearing 11. The inner ring of the bearing 11 is fixedly connected to the surface of the rotating rod 303. By setting the bearing 11, the friction and resistance when the rotating rod 303 rotates can be reduced, making the rotating rod 303 rotate more smoothly.

[0030] Reference Figure 3 The inner wall of the mounting box 301 is fixedly connected to the mounting base 12, and the hose 304 is fixedly connected to the inner wall of the mounting base 12. By setting the mounting base 12, the hose 304 in the mounting box 301 can be limited to prevent the hose 304 from shifting and ensure that the roller 306 can squeeze the hose 304.

[0031] Reference Figure 1 and Figure 4 The top of the liquid storage tank 310 is fixedly connected to the positioning frame 6, and the hose 304 passes through the inner wall of the positioning frame 6. By setting the positioning frame 6, the hose 304 can be supported and fixed, and the hose 304 can be fixed to the top of the filter tank 2, so that the cleaning liquid can clean the filter membrane in the filter tank 2.

[0032] Reference Figure 4 A connecting frame 13 is fixedly connected to one side of the positioning frame 6, and an elastic block 14 is fixedly connected to one side of the connecting frame 13. There are two elastic blocks 14. The elastic blocks 14 are used in conjunction with the diversion pipe 308. By setting the connecting frame 13, the elastic blocks 14 can be provided with support force to ensure the stability of the elastic blocks 14. The idle diversion pipe 308 can be fixed by the elastic blocks 14.

[0033] Working Principle: The sample to be tested is drawn into the filter tank 2 through a squeezing pipe and filtered through a filter membrane. Microorganisms are trapped on the filter membrane. The filter membrane is rinsed with cleaning solution to remove impurities or residues that may affect subsequent culture. An appropriate amount of nutrient culture medium is added to the filter membrane to provide nutrients for microbial growth. The device with the filter membrane and culture medium is placed in a constant temperature incubator and cultured at a suitable temperature for a period of time. After culture, the colony-forming units on the filter membrane are observed under a microscope and counted to determine the microbial content in the sample. When the sample is injected into the filter tank 2, it will be filtered through the filter membrane. Impurities in the sample need to be removed with cleaning solution. The user injects the cleaning solution into the storage tank 310 through the water inlet pipe 4. The user can start the motor 302 through an external control switch. The motor 302 is powered by an external power supply, and the output of the motor 302 drives the rotation. Rotating rod 303 rotates, which in turn drives support frame 305 to rotate. Roller 306 mounted on support frame 305 moves with the rotation of support frame 305, thereby periodically squeezing hose 304 located in mounting base 12, pushing cleaning liquid forward. Mounting base 12 can prevent hose 304 from shifting when squeezed. Through continuous squeezing of hose 304 by roller 306, the pressure change inside hose 304 causes cleaning liquid in storage tank 310 to be drawn out and move along the path of hose 304 to corrugated telescopic tube 307, and then flow into diversion tube 308 through corrugated telescopic tube 307. Diversion tube 308 is inserted into filter tank 2, and cleaning liquid is sprayed into filter tank 2 through nozzle 309 on diversion tube 308 to rinse impurities in filter membrane, avoiding excessive or insufficient cleaning liquid, and ensuring the quantitative and stable rinsing process.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
