Description

Technical Field

[0001] The utility model belongs to the technical field of microbiology, and in particular relates to a sampling device for detecting microbial agents. Background Art

[0002] The sampling device for microbial agent testing plays a vital role in the microbial testing process. The sampling device is used to evenly collect samples from the microbial agent sample to ensure that the sample can represent the characteristics of the entire sample population. The sampling device is usually operated aseptically to prevent contamination by external microorganisms and ensure the purity of the sample. Samples are collected in sterile containers or sterile bags to prevent contamination during transportation and storage.

[0003] Some sampling devices for microbial agent detection in the prior art usually require manual pulling of the piston for sampling. Manual operation is prone to human errors, affecting the accuracy of the sampling results. In addition, the sampling speed of manually pulling the piston is slow, especially when multiple or large-scale sampling is required, the efficiency is relatively low. At the same time, manually pulling the piston is more difficult when sampling high-viscosity liquid microbial agents, and it is easy to get stuck or difficult to completely pull out.

The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Example

[0025] Reference Figures 1 to 4 , is an embodiment of the present utility model, which provides a sampling device for microbial agent detection, which can achieve the effect of accurately controlling the flow rate and sampling volume of the microbial agent without manual sampling, and effectively sampling high-viscosity liquid microbial agents.

[0026] The supporting mechanism 100 includes a sampling platform 101, a microbial agent bottle 102 mounted on top of the sampling platform 101, a support frame 103 and a test tube rack 104 fixedly mounted on the top of the other side of the sampling platform 101, a glass test tube 105 mounted on the inner surface of the test tube rack 104, and a sterile bag 106 mounted on one side of the glass test tube 105;

[0027] It should be noted that the inoculant bottle 102 is used to hold microbial inoculant samples. The inoculant bottle 102 is made of low-borosilicate glass that has good corrosion resistance to most chemicals. The support frame 103 is used to support the sampling mechanism 200. The user can choose a glass test tube 105 or a sterile bag 106 as the inoculant container according to the actual sampling needs. The glass test tube 105 has good heat resistance and can be sterilized at high temperature, which is suitable for routine operations in the laboratory. The sterile bag 106 has a large capacity and is easy to carry and transport. It is suitable for samples that need to be transported and stored for a long time to ensure the sterility and stability of the sample.

[0028] And, a sampling mechanism 200 is provided on the outer surface of the support frame 103 and is used in conjunction with the inoculant bottle 102 .

[0029] It should be noted that, through the coordination of the various components in the sampling mechanism 200 , it is possible to achieve the effect of accurately controlling the flow rate and sampling volume of the inoculum without manual sampling, and effectively sampling high-viscosity liquid inoculum.

[0030] Specifically, there are a plurality of glass test tubes 105 , and outer surfaces of the plurality of glass test tubes 105 are in sliding contact with the inner surface of the test tube rack 104 .

[0031] Furthermore, the sampling mechanism 200 includes a fixing box 201 fixedly connected to the top of the support frame 103 , and a protective cover 202 fixedly installed on the outer surface of the fixing box 201 .

[0032] Preferably, the sampling mechanism 200 further includes a servo motor 203 adapted to be mounted at the bottom of the support frame 103 , a connecting shaft 204 fixedly connected to the output end of the servo motor 203 via a coupling, and a turntable 205 fixedly mounted at the through end of the connecting shaft 204 .

[0033] It should be noted that the positioning accuracy and speed control accuracy of the servo motor 203 are relatively high, and the user can adjust the speed of the servo motor 203 according to the sampling amount of the bacterial agent required.

[0034] It should be noted that squeezing rollers 206 are fixedly mounted on the inner walls of both sides of the turntable 205 via bearings, and a sampling hose 207 is provided in the inner cavity of the fixed box 201 .

[0035] The squeezing roller 206 can periodically squeeze the hose 207 to force the inoculant liquid in the hose 207 to flow forward. Each squeezing pushes the inoculant liquid in one section of the hose 207 to the next unsqueezed section. The hose 207 quickly returns to its original shape after being squeezed, and negative pressure is formed in the tube to absorb new inoculant liquid, ensuring the continuous flow of the inoculant liquid, thereby achieving continuous liquid transmission.

[0036] Furthermore, the sampling mechanism 200 further includes a tube sleeve 208 which is mounted on the outer surface of the sampling hose 207 , and a motor frame 209 which is fixedly connected to the bottom of the support frame 103 and cooperates with the servo motor 203 .

[0037] It should be explained that the sleeve 208 is used to fix the hose 207 to prevent the position of the hose 207 from shifting, and the motor frame 209 is used to fix the servo motor 203.

[0038] Specifically, the outer surface of the squeezing roller 206 is in sliding contact with the outer surface of the sampling hose 207 , the through end of the sampling hose 207 is connected to the inner cavity of the microbial agent bottle 102 , the outer end surface of the tube sleeve 208 is fixedly connected to the outer surface of the fixed box 201 , and the outer surface of the servo motor 203 is fixedly connected to the inner surface of the motor frame 209 .

[0039] During use, one end of the hose 207 is inserted into the inoculant bottle 102, and the other end is inserted into the glass test tube 105 according to actual sampling requirements, or fixedly connected to the bag opening of the sterile bag 106. The servo motor 203 is turned on to drive the connecting shaft 204 to rotate, so that the connecting shaft 204 drives the turntable 205 and the squeezing roller 206 to rotate synchronously. The squeezing roller 206 periodically squeezes the hose 207, forcing the inoculant liquid in the hose 207 to flow forward. Each squeezing pushes the inoculant liquid in one section of the hose 207 to the next unsqueezed section. After being squeezed, the hose 207 quickly returns to its original shape and forms a negative pressure in the tube to absorb new inoculant liquid, ensuring the continuous flow of the inoculant liquid, thereby achieving continuous liquid transmission.

[0040] In summary, the carrying mechanism 100 can facilitate the user to flexibly adjust the sampling container according to actual sampling needs. Through the cooperation between the various components in the sampling mechanism 200, the flow rate and sampling volume of the microbial agent can be accurately controlled without manual sampling, and high-viscosity liquid microbial agents can be effectively sampled to achieve automated sampling, reduce the user's labor intensity, improve the accuracy of sampling, and adapt to the effects of multiple sampling or large-scale sampling. It can also effectively protect the microbial agents in the high-viscosity liquid microbial agent from damage and maintain its activity and integrity.
