The first embodiment is suitable for the scene of pouring all nutrient solutions fast once, and the auxiliary strip which can be drawn and rotated is added on the basis, so that the sealing cover is taken out more safely, the sampling test is more rapid, convenient and environment-friendly, and the specific working process is as follows:

in the daily idle state, the sealing bulge at one end of the auxiliary strip is buckled in the through hole of the sealing cover 7, the auxiliary strip at the other end is positioned in the packaging bag body in a sagged shape because the length of the auxiliary strip is larger than the boundary size of the packaging bag, before the sealing cover is taken out, the sealing bulge is pulled out, then the sealing bulge is rotated to drive the auxiliary strip in the packaging bag to stir the culture medium solution, then the auxiliary strip is pulled outwards, so that the outside air is communicated with the internal culture medium, the packaging bag which is originally squashed by air pressure is re-bulged, in the process of pulling out the auxiliary strip, the length of the auxiliary strip positioned in the packaging bag is shortened, and because the auxiliary strip has certain flexibility, the residual length of the auxiliary strip in the packaging bag is shorter, the auxiliary strip is flatter and straight, and the sealing cover is positioned at the upper part of the bag body, therefore when the residual length of the auxiliary strip in the packaging bag which is pulled out, the auxiliary strip in the packaging bag is in a straight strip shape and is integrally attached to the upper edge of the packaging bag, the auxiliary strip in the packaging bag plays a role of a supporting frame at the moment, an operator uses one hand to clamp the tail end part of the auxiliary strip at the upper edge of the packaging bag through the packaging bag at the moment so as to integrally fix and clamp the upper edge of the packaging bag, and uses the other hand to pull out the sealing cover, so that the upper edge of the packaging bag is fixed and clamped, and the accidental situations that the packaging bag is accidentally deformed again and the internal culture solution is accidentally sprayed are avoided. After the sealing cover is pulled out, the culture solution is taken out, the sealing cover is buckled, then the auxiliary strip is pushed into the packaging bag until the sealing bulge is buckled in the through hole of the sealing cover, and therefore the complete culture medium taking operation is finished.

In addition, if micro-sampling measurement of the components in the medium is required, the following procedure is adopted: at first extract this sealed arch, thereby it stirs culture medium solution to rotate this sealed protruding interior auxiliary strip of drive wrapping bag, treat the stirring back, then press close to and counter-rotating this sealed bellied arrow head and the directional sign on the sealed lid, refer to this sealed bellied arrow head this moment, thereby make the sample check that lies in on the auxiliary strip in the wrapping bag splendid attire solution up, then outside slowly pull this auxiliary strip, avoid the rotation of auxiliary strip in the pulling in-process, thereby guarantee smooth taking out culture medium solution, when a plurality of sample check on the auxiliary strip remove to the outside of wrapping bag, utilize outside suction means such as burette to get the liquid operation this moment can. Furthermore, the volume of the sampling grid on the auxiliary strip can be a pre-support volume, for example, the volume of one sampling grid is 1ml, so that quantitative liquid taking can be realized. In addition, the auxiliary strip and the sealing bulge are detachably connected, so that the auxiliary strip of the prefabricated volume sampling grids of different specifications can be replaced, and the operation is more convenient.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
