Specific embodiment
As shown in FIG. 1 to 3, a kind of molecular biology test Special rat syringe, including syringe and with note
The rat fixator that emitter is slidably connected, rat fixator include cylinder 5, head bore 12 and back plate 3, the setting of 5 top center of cylinder
Injection port 8,8 top two sides of injection port are provided with syringe and place slideway, and syringe bottom, which is provided with, places slideway with syringe
The pedestal 2 matched, syringe include needle tubing 1, plunger 14, syringe needle 9 and inlet opening 15 and gas vent that 1 top of needle tubing is arranged in
20。
Syringe can be placed in slideway from syringe along pedestal 2 and be extracted out when use.
The setting of gas vent 20 is provided with exhaust valve 16, inlet opening 15 at the top of 15 front end of inlet opening, gas vent 20
It is connected by hose 19 with explosive box 17, is provided with administration pump 18 at the top of the explosive box 17.
It is provided with needle protecting cover 21 outside the syringe needle 9, needle protecting cover 21 is connected through a screw thread with needle tubing 1.
Head bore 12 is arranged in 5 front end of cylinder, and 5 rear end of cylinder is provided with back plate 3, and the diameter of back plate 3 is slightly less than cylinder 5
Diameter, 3 bottom of back plate is connected by slideway 7 with 5 bottom of cylinder.
The slideway 7 is dove tail shape or T-type, and 3 bottom of back plate is provided with the sliding block 6 matched with 7 shape of slideway.
5 rear portion of cylinder is provided at least three baffle holes 2 11, and the side of back plate 3 is provided with through back plate 3
Baffle holes 1, baffle 4 pass through baffle holes 1 and the fixed back plate 3 of baffle holes 2 11, and the length of baffle 4 is greater than the outer of cylinder 5
Diameter.
The administration pump 18 is connected with hose 19 and explosive box 17.
It is provided with scale on the needle tubing 1, is provided with uropore 13 below the back plate 3.
5 two sides of the bottom of cylinder are respectively provided with two leg holes, for fixing four legs of rat.
When the utility model is used, first baffle 4 is extracted out from baffle holes 1 and baffle holes 2 11, opens needle tubing 1 and pushes up
The plunger 14 of needle tubing 1 is pulled at the scale of required medical fluid, by syringe needle 9 by the exhaust valve 16 on the gas vent 20 at end backward
It removes, the opening of 1 front end of needle tubing is sealed up with threaded lid, then open administration pump 18, medical fluid is along hose 19 from feed liquor
