detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1-4, the utility model provides a kind of technical solution: a kind of medicine analysis microquantitative sampling preservation device, comprises medicine storage tank 1 and sealing end cap 11, and the front part of described medicine storage tank 1 is provided with transparent observation plate 9, the front portion of the transparent observation plate 9 is provided with a scale 10, and the middle part of the upper end of the medicine storage tank 1 is screwed with a medicine taking tube 6 through an internal thread 3, and a medicine suction tube 6 is arranged inside the medicine taking tube 6. Pipe 4, external thread 8 is provided on the outside of the upper end of the drug storage tank 1, a groove 7 is provided between the internal thread 3 and the external thread 8, and the sealing end cap 11 is screwed to the drug storage tank through the external thread 8 At the upper end of the tank 1 , a protrusion 13 is provided inside the sealing end cap 11 .

Further, both sides of the middle part of the medicine storage tank 1 are provided with arc-shaped grooves 2, and the surface of the arc-shaped groove 2 is provided with anti-skid protrusions.
