Sampling device for regularly detecting microorganisms

[0036] This embodiment provides a sampling device for periodic detection of microorganisms, including an injection tube 1, the head end of the injection tube 1 is connected with a detachable needle 2, and the injection tube 1 is made of a steel pipe, a ceramic tube or a transparent glass tube. The needle 2 is used for direct contact with the microbial sample liquid. There is a push rod 3 inside the injection tube 1. Push the push rod 3 in the direction of the needle 2 to discharge the air in the injection tube 1, and then pull the push rod 3 to the outside of the injection tube 1. , the microbial sample liquid enters the interior of the injection tube 1, and the side wall of the injection tube 1 is provided with a liquid separation hole 11 at 1-4 cm from the tail end of the needle 2, and a sampling bag 4 is detachably connected to the liquid separation hole 11. 4 is located outside the injection tube 1, and the outside of the injection tube 1 is provided with a extrusion assemb...

[0044] A sampling device for periodic detection of microorganisms, basically the same structure as in Example 1, the difference is that see Figure 5 , in order to reduce the work of cleaning the instrument and improve the utilization rate of the instrument, the present invention also includes a head end installation sleeve 9 and a tail end installation sleeve 91. Externally, one end of the pressure plate 5 is rotatably connected to the head-end mounting sleeve 9 instead of being mounted on the injection tube 1, the tail-end mounting sleeve 91 is sleeved and clamped on the tail end of the push rod 3, and the other end of the pressure plate 5 is rotatably connected to the The tail end is installed on the sleeve 91, but not on the push rod 3. Before sampling, install the head end installation sleeve 9 and the tail end installation sleeve 91 according to Figure 5 The shown structure is installed in the corresponding position, and then samples are taken according to the working ...
