Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 3, semi-automatic sample presentation needle of the invention, it includes needle tubing 1 and syringe needle 2, it further includes cylinder type ontology 3,
1 one end of needle tubing is connect with syringe needle 2, and rotating needle 2, replacement is easier, and 1 other end of needle tubing is connect with cylinder type ontology 3, needle tubing 1
The other end protrudes into cylinder type ontology 3, and the two is fastenedly connected, and passes through the quick compression bar of a balance bracket 4 and top outside cylinder type ontology 3
5 connections, quick compression bar 5 are fastened, and nonvoluntary movement, quick compression bar 5 is located at the top of needle tubing 1 and cylinder type ontology 3, and and needle tubing
1 is parallel with cylinder type ontology 3, and the front end of quick compression bar 5 is provided with tripping spring 6,6 upper end of tripping spring and quick 5 bottom surface of compression bar
Wall connection, the tripping spring 6 act on downwards 3 outer wall of cylinder type ontology, the one speed regulation guide rod 7 of rear end setting of quick compression bar 5, speed regulation
The lower end of guide rod 7 acts on inside cylinder type ontology 3, and the liquid measure pull rod 8 for pull medical fluid is provided in cylinder type ontology 3.
The liquid measure pull rod 8 includes aspiration needle 81, piston boit 82 and pull rod handle end 83, and needle tubing 1 is protruded into 81 one end of aspiration needle
Interior, 81 other end of aspiration needle is connect with 82 one end of piston boit in cylinder type ontology 3, outside 82 other end of piston boit and cylinder type ontology 3
Pull rod handle end 83 connect.When hand holds pull rod handle end 83, by pull power by liquid the pull from medicinal liquid bottle
Enter needle tubing 1 from syringe needle out.
Piston boit 82 includes cylinder 821, is placed on the piston head 822 of 821 one end of cylinder and is placed on the system of 821 other end of cylinder
Determine ring 823, is cased with interior pressure spring 824 on the cylinder 821 between piston head 822 and formulation ring 823.When pull, interior pressure spring 824
It is extruded, after pull, medical fluid is transferred to (when animals), only needs flicking pull rod handle end 83, so that it may
It automatically resets.
3 end of cylinder type ontology is provided with fixed knob 9, covers on formulating the cylinder 821 between ring 823 and fixed knob 9
There is insurance fixed ring 825, fixed ring end 83 is against 9 inside of fixed knob.
The effect of fixed knob 9: after liquid measure pull rod completes drawing liquid, the ring 825 that is locked of fixed knob 9 is fixed, to be used
When just open fixed ring 825, press quick 5 drug delivery of compression bar.(discharge cock of such as pistol, in experimentation, there are many beam workers
Make, or there are multiple drug delivery processes, therefore insurance in advance is needed to fasten).
