Description

Technical Field

[0001] The utility model relates to the technical field of aseptic sampling, in particular to a probiotics aseptic sampling device. Background Art

[0002] Probiotics are active microorganisms that are beneficial to the human body. They exist in the human intestines, help maintain the balance of intestinal flora, inhibit the growth of harmful bacteria, promote digestion and absorption, and enhance immunity. In the fields of pharmaceuticals, biotechnology, food and beverages, etc., a sterile sampling device is usually required to quickly and safely remove samples from samples containing probiotics, ensure the sterility of the sampling process, avoid cross contamination, and reduce the loss of sample activity during sampling, transportation and testing, thereby improving the accuracy of the test results.

[0003] According to the search, Chinese patent literature, announcement number: CN220907487U, discloses an aseptic sampling device, which is provided with a sealing mechanism to increase the sealing performance of the aseptic sampling device, ensure that the sampled stock solution is not contaminated, and by providing multiple sampling heads on the sampler, the device can take out multiple groups of sample liquids at a time, thereby improving the efficiency of stock solution sampling. However, in actual use, the device squeezes the stock solution into the inside of the collection hose by pressing the squeezer. Therefore, after the device completes sampling, the liquid inlet is in an open state, so the stock solution cannot be sealed, and the stock solution will flow into the inside of the liquid inlet and other parts, which not only causes certain pollution, but also wastes part of the stock solution and loses its activity. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a probiotic aseptic sampling device, which has the advantages of good sealing, avoiding pollution, easy operation, and improved work efficiency, and solves the above technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a probiotic aseptic sampling device, comprising a sampler body, a through hole is opened inside the sampler body, a first groove and a second groove are opened inside the through hole, an extrusion sleeve is installed inside the first groove, a spring and a sampling needle tube are fixedly installed on the right side of the extrusion sleeve, a sealing rubber ring is fixedly installed inside the second groove, a limiter is installed on the outer side of the extrusion sleeve, a liquid outlet pipe is fixedly connected to the left side of the extrusion sleeve, a metal sleeve is fixedly installed on the end of the liquid outlet pipe away from the extrusion sleeve, a sampling bag is fixedly connected to the bottom end of the metal sleeve, a connecting seat is installed on the right side of the sampler body, and a silicone needle sleeve is installed inside the connecting seat.

[0008] Preferably, the number of the through hole, the first groove, the extrusion sleeve and the spring is four, and one end of the spring away from the extrusion sleeve is fixedly connected to the inside of the first groove.

[0009] Through the above technical solution, when the four extrusion sleeves are pressed separately, the extrusion sleeve can drive the sampling needle to move to the right for sampling, and the spring will be compressed at the same time. Then, when the sampling is completed, the extrusion sleeve is released, and the extrusion sleeve, the sampling needle and other parts can be restored to their original positions under the reaction force of the spring, thereby improving the overall practicality of the device and ensuring the sterility of the sampling process.

[0010] Preferably, the number of the sampling needle tubes is four, and a fixing plate is provided inside each of the four through holes, and the four sampling needle tubes are correspondingly installed inside the four fixing plates.

[0011] Through the above technical solution, when the extrusion sleeve drives the sampling needle tube to move inside the through hole, the fixing plate can effectively limit the position of the sampling needle tube, so that it remains in the correct direction when inserted or withdrawn, thereby improving the safety and stability of the sampling process.

[0012] Preferably, the number of the second groove, the sealing rubber ring and the silicone needle sleeve is four.

[0013] Through the above technical solution, when the extrusion sleeve drives the sampling needle tube to move to the right, the sampling needle tube can pierce the silicone needle tube and take samples. After the sampling is completed, the sampling needle tube leaves the position of the silicone needle tube. Since silicone has good elasticity and a certain self-healing ability, it can fill the small gaps to a certain extent for such small-area damage, so that the silicone needle tube can maintain a certain sealing performance even after damage, thereby preventing sample leakage; on the other hand, even if the sample leaks from the silicone needle tube, the four sealing rubber rings can prevent it from leaking again, providing double protection for the device, avoiding cross contamination, and improving the overall sealing.

[0014] Preferably, the number of the limiter, the liquid outlet pipe, the metal sleeve and the sampling bag are all four.

[0015] Through the above technical solution, when sampling, the limiter can be removed from the outer side of the extrusion sleeve to press it and take samples. However, when installing the entire device, or for the extrusion sleeve after sampling, the limiter can be installed on its outer side, thereby effectively preventing damage to the device or sample leakage due to accidental touch and other operations, thereby improving the overall practicality of the device; in addition, after the sampling is completed, the sampling bag can be sealed and separated by using tools such as disconnecting pliers to clamp off the corresponding metal sleeve, thereby improving the convenience and sterility of the entire device.

[0016] Preferably, a mounting hole is provided on the left side surface of the connecting seat, and a sealing gasket is installed inside the connecting seat.

[0017] Through the above technical solution, parts such as bolts are installed inside the mounting hole, and parts such as the connecting seat can be installed on the sampling container together, thereby realizing the connection between the devices, and the sealing gasket can effectively prevent the sample liquid from leaking from the connecting seat, thereby improving the overall sealing of the device.

Since silicone has good elasticity and a certain self-repairing ability, it can fill the small gaps in such small areas to a certain extent for such small-area damage, so that the silicone needle sleeve can maintain a certain sealing performance even after damage, thereby preventing sample leakage; on the other hand, even if the sample leaks from the silicone needle sleeve, the four sealing rubber rings can prevent it from leaking again, providing double protection for the device, avoiding cross contamination, and improving the overall sealing.
