Specific implementation mode
Embodiment one:
Revealed the utility model is a kind of needle tube type microbial identification micro biochemical pipe, a kind of needle tubing as shown in Figure 1
The bioassay that declines micro biochemical pipe, including injection needle 1, biochemical reaction pipe 2, needle holder 3, interior be equipped with of injection needle 1 are injected
The surface of pipe 12, injection needle 1 is equipped with several volume graduation marks 13, as shown in Fig. 2, 2 front end of biochemical reaction pipe and needle holder 3
It is connected, rear end is connected with injection needle 1, and 2 rear end of biochemical reaction pipe is equipped with sealing device, and sealing device preferably uses sealing strip
22, sealing strip 22 can directly select sterile plastic foil, in this way can be cost-effective, and sealing strip is with biochemical reaction pipe 2 using viscous
The mode of connecing connects, and has the biochemical dry powder 21 made of biochemical substrates in biochemical reaction pipe 2, which can be directly by ready-made
Solid-state biochemistry powder grind;3 front end of needle holder is equipped with syringe needle 31, and syringe needle 31 can be metal needle, can also plastic needle
Head, syringe needle 31 are equipped with needle cover 32;Biochemical reaction pipe 2, needle holder 3, syringe needle 31 are connected as one to be seeded micro- as one
Biochemical tube 4 is measured,
The application method of the utility model embodiment one is:
Before inoculation, several are first configured by biochemical reaction pipe 2, needle holder 3, the micro life made of being connected as one of syringe needle 31
Change pipe 4, configuration method is in an aseptic environment, to take out the micro biochemical pipe 4 of integrally connected, take different types of sterile life
Change dry powder 21 to be placed in biochemical reaction pipe 2, then by sterile plastic foil by adhering and sealing, preventing the biochemical dry powder in the inside
21 make moist, these micro biochemical pipes 4 are disposable, will be abandoned after being finished.After configuring, by several 4 rows of micro biochemical pipe
Row are good spare;Purebred bacterial clump to be identified is tuned into 0.5 Maxwell than turbid bacteria suspension in advance, is placed in sterile small test tube
It is spare;When inoculation, this sealing strip 22 of tearing, or sealing strip 22 is directly broken, injection needle 1 and biochemical reaction pipe 2 are connected
It connects, then pulls and inject pipe 12, the bacterium solution for carefully drawing certain scale completes operation, in order to avoid drawing the amount mistake of bacterium solution
Greatly, the volume of limit volume and certain scale that syringe can pull has been previously set, for example, four volume graduation marks of setting
13, four volume graduation marks are respectively set, can thus so that the bacterial concentration that every pipe is drawn with volume is as, to protect
The bacterial number that card is often inoculated in pipe is relatively uniform, directly pulls out injection needle 1 after being inoculated with, then with other micro biochemical pipes
It directly uses, injection needle 1 may be reused in the case that not contaminated.
Embodiment two:
It is compared as shown in Figure 3, Figure 4 with embodiment one, the sealing device in embodiment two uses sealing cover 23, such as Fig. 3 institutes
Show, which is connected with biochemical reaction pipe 2 by buckle structure, has one to be opened with what needle tubing was connected on sealing cover 23
Mouthfuls 231, in opening there are one small lid 232.
Before use, in an aseptic environment, taking out the micro biochemical pipe 4 of integrally connected, sealing cover 23 is opened, variety classes are taken
Biochemical dry powder 21 be placed in biochemical reaction pipe 2 and then cover sealing cover, while putting needle cover at syringe needle, ensure entire biochemical anti-
Should pipe 2 is sterile and leakproofness, prevent the biochemical dry powder in the inside 21 from making moist.These micro biochemical pipes 4 be it is disposable, will after being finished
It abandons.After configuring, several micro biochemical pipes 4 are arranged spare;Bacterial clump to be identified is tuned into 0.5 Maxwell ratio in advance
Turbid outstanding bacterium solution is placed in spare in sterile small test tube;When inoculation, the small lid 232 in the opening 231 of sealing cover 23 is opened, it will
Injection needle 1 is directed at the opening 231, then pulls and injects pipe 12, and the bacterium solution for carefully drawing certain scale completes operation.
