Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described.Based on reality of the present utility model
Example is applied, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is all belonged to
In the scope of the utility model protection.
A kind of micro-sampler for medical inspection, as shown in Figure 1 to Figure 3, including syringe 1, piston rod 2, light-resistant sleeve 3,
The piston rod 2 is provided with the syringe 1, the piston rod 2 is provided with positioning strip 201, and the end of piston rod 2 is provided with push rod
202, the front end of syringe 1 connection is provided with light-resistant suction pipe 4, and the light-resistant sleeve 3 is arranged with outside the syringe 1, described to keep away
Bar groove side 301, scale line side 302 are arranged with the outer wall of light type sleeve 3, cunning is arranged with the outer wall of light-resistant sleeve 3
Dynamic cutting ferrule 5, the slip outer wall of cutting ferrule 5 are provided with locating rod 501, and the top of locating rod 501 is rotatably provided with location-plate
