Abstract
Description
Technical Field
[0001] The utility model relates to the field of biological sampling, in particular to a biological sampler. Background Art
[0002] Currently, sampling, culturing, observing and studying the microorganisms in research samples are common tasks in medical testing. Cultivation and analysis of microorganisms help medical personnel determine the type of disease and provide assistance for medical treatment research. When performing various testing operations on microorganisms, it is first necessary to sample the microorganisms.
[0003] At present, the commonly used sampling device is a sampling tube, and a rubber ball is installed at the upper end of the sampling tube. When it is necessary to take out, the rubber ball is pressed to make the inside of the sampling tube a negative pressure state, so that the sample can be sucked for sampling. However, in the actual use process, it is found that: due to the different amounts of samples taken out and discharged each time, it is impossible to sample completely and accurately with a rubber ball of a certain size, which leads to sample waste and affects the accuracy of the test. For this reason, a biological sampler is proposed. Utility Model Content
[0004] In view of the above problems existing in the existing biological samplers, the present utility model is proposed.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:
[0015] 1. The utility model is provided with a plurality of rubber airbags, and each rubber airbag has a different size. The rubber airbag of the corresponding size can be selected according to the amount of sampling required, and the sample can be accurately taken out or discharged, thereby avoiding sample waste and improving the accuracy of the inspection.
[0016] 2. The utility model provides switch valves on a plurality of suction tubes. When one of the rubber airbags is used, the switch valves corresponding to the other rubber airbags can be closed to ensure that the sampling operation is completed.
[0017] 3. The utility model provides a gripping handle on the sampling tube, and the gripping handle is composed of an inner ring, an outer ring and a fixing rod. During the sampling operation, the inspector can hold the outer ring tightly with his hand, so that the sampling tube can be vertically inserted into the sample. BRIEF DESCRIPTION OF THE DRAWINGS
