Pollute.
In above-mentioned technical proposal, needle point line and the needle tubing 200 of the syringe needle 400 of the first syringe needle 300 and second
Length direction is consistent, and the needle point opening of the syringe needle 400 of the first syringe needle 300 and second is back to setting, that is to say, that the first syringe needle
300 and second syringe needle 400 needle point on same axis, be on the one hand easy to needle tubing to be inserted into cillin bottle, meanwhile, can subtract
It is small to be retained in the hole diameter that cillin bottle is covered, it is to avoid the liquid in cillin bottle overflows or diffused out from bottle cap, causes dirt
Dye.
In above-mentioned technical proposal, as shown in figs. 1 and 3, offered if being spaced to run through on the lateral wall of second syringe needle 400
Dry through hole 410, the through hole 410 connects the second channel 420, when the liquid level in cillin bottle is higher than the of second channel 420
During two ends, now, if do not open up the air in through hole 410, cillin bottle be in the same old way can not be by the water conservancy diversion of second channel 420 to outer
Boundary, in the present invention, no matter the second syringe needle insertion depth is how many, or how liquid level changes in cillin bottle, as long as having one
Individual through hole is retained in the cillin bottle external world, while another through hole is in the cavity in cillin bottle, you can with by cillin bottle
Gas flow guiding is to outside cillin bottle, it is ensured that injection needle balances the function of cillin bottle inner and outer air pressure.
Embodiment two
As viewed in figures 5-8, different from embodiment one to be, the needle tubing 200 is interior crosspointer header structure, the needle tubing
It is divided into 200 and is disposed in parallel in the first syringe needle 300 and the second syringe needle 400, second syringe needle 400 is arranged on first syringe needle
300 outsides, equivalent to independent double pipe structure, the tube wall of the upper and lower ends of the second syringe needle 400 are cut away so that second syringe needle
400 are located between the first end of the first syringe needle 300 and the second end, while by the madial wall of needle tubing 200 and first pin
First 300, the gap 500 between the lateral wall of the second syringe needle 400 is filled densification, it is to avoid in the madial wall of needle tubing 200 and described first
Gap is caused between syringe needle 300, the lateral wall of the second syringe needle 400, needle tubing air-tightness is influenceed.
A dividing plate 430 can also will be vertically arranged with the middle of needle tubing 200, needle tubing is divided into the first separate syringe needle
300 and second syringe needle 400, channel structure is formed, the tube wall of the upper and lower ends of the second syringe needle 400 is cut away so that described second
Syringe needle 400 is located between the first end of the first syringe needle 300 and the second end.
Other structures are identical with embodiment one.

Road 420 is spaced apart.Specifically, the first passage 310 is parallel with the length direction of second channel 420, outside the needle tubing 200
Interval is through some through holes 410 are offered on the wall of side, and the through hole 410 connects the second channel 420, second channel 420
Length is less than the length of the first passage 310, and second channel 420 is located at the first end and second of the first passage 310
Between end.
When needle tubing 200 is inserted into cillin bottle, with the increase of insertion depth, the end of second channel 420 second is just suitable
Band is inserted into cillin bottle, and the second end of second channel 420 is connected with the headroom in cillin bottle, and the of second channel 420
Open at one end is in atmosphere, that is to say, that the headroom in cillin bottle is in communication with the outside by second channel 420, works as cillin bottle
In air pressure it is too high when, you can the end of second channel 420 second is inserted into cillin bottle, the gas in cillin bottle imported into outer
Boundary, equilibration flask inner air and outer air pressure.
When needing to inject radioactive solution or physiological saline into cillin bottle, needle tubing is inserted into cillin bottle, promoted
Radioactive solution or physiological saline are injected into cillin bottle by syringe by first passage 310, in injection process, cillin bottle
Interior air surge tank must more and more higher, the liquid volume particularly injected is excessive or during too fast injection rate, it is necessary to by needle tubing after
It is continuous to be inserted downwardly into cillin bottle, the end of second channel 420 second is taken advantage of a situation and is inserted into cillin bottle, by the first end of the second syringe needle
It is retained on the outside of cillin bottle, now, the connection cillin bottle inner space of second channel 420 and ambient atmosphere, the air pressure in cillin bottle
Air in superatmospheric, cillin bottle will be by the water conservancy diversion of second channel 420 to the external world, so as to balance inside and outside cillin bottle
Air pressure, with the continuation of injection process, the air pressure inside and outside cillin bottle is equal all the time, so as to effectively prevent due to cillin bottle
Interior air compression pressure is excessive, when extracting syringe needle, and the radioactive liquid in cillin bottle oozes out or sprayed from bottle cap, causes dirt
Dye.
In above-mentioned technical proposal, when the liquid level in cillin bottle is higher than the second end of second channel 420, now, if not
Open up air in through hole 410, cillin bottle in the same old way can not by the water conservancy diversion of second channel 420 to the external world, in the present invention, no matter
Second syringe needle insertion depth is how many, or how liquid level changes in cillin bottle, as long as there is a through hole to be retained in cillin bottle
The external world, while another through hole is in the cavity in cillin bottle, you can with by outside the gas flow guiding in cillin bottle to cillin bottle,
It ensure that injection needle balances the function of cillin bottle inner and outer air pressure.
