Problems solved by technology
[0006] However, the existing sampling system equipment has complex structure, cumbersome operation, and poor flexibility, and is not suitable for cell culture systems that require regular sampling and testing. Therefore, for cell culture fluid that requires regular sampling for quality inspection, it is necessary to design a small sampling device

The invention provides a sterile sampling device and a using method thereof. The sterile sampling device comprises a preset pipe fitting, a fixing part and a puncture assembly. The preset pipe fittingis connected into a pipeline system of a to-be-sampled material in advance, and a sampling opening of the preset pipe fitting is externally connected with the fixing part of a piston structure. The fixing part comprises a sealed fixing cavity and a fixing part penetrating into the fixing cavity, the fixing cavity is communicated with the preset pipe fitting through the sampling opening, and a limiting part is arranged on the fixing part and used for limiting one-way movement of the fixing part. Tthe puncture assembly comprises a puncture part used for blocking a sampling opening of the presetpipe fitting and a puncture needle combined with the fixing part, the fixing part drives the puncture needle to move in the puncture direction in the one-way propelling process, the puncture part ispunctured by the puncture needle and inserted into the preset pipe fitting, and the to-be-sampled materials flowing in the preset pipe fitting is collected. Internal sealing of the sampling device isachieved, and external environment pollution and leakage of pathogens in cell culture fluid in the sampling process are effectively avoided.
Description
technical field [0001] The invention belongs to the technical field of sampling equipment, and relates to an aseptic sampling device and a using method thereof, in particular to a small aseptic sampling device and a using method thereof. Background technique [0002] During the cell culture process under fully enclosed conditions, it is necessary to regularly sample the cell culture medium for quality inspection. On the one hand, it is necessary to strictly consider the aseptic requirements of the cell culture medium during the sampling process, and no external pathogens are allowed to enter the cell culture environment; Impact. [0003] CN108998365A discloses a rapid aseptic detection device and rapid detection method, that is, on the tank body, a hollow pipe column extending to the inside of the tank body is formed integrally with the tank body; a top is provided with an elastic plug at the bottom of the pipe column The sampling needle; above the sampling needle, there i...
