Description
Technical field
The utility model belongs to the field of medical instrument technology, and in particular to a kind of syringe.
Background technology
Nuclear medicine image, either SPECT/CT check or PET/CT is checked, are required for injecting medicine to patient.Especially
It is that SPECT/CT is checked, causes injection medicine different according to checking that internal organs are different, image purpose difference, the method for injection is different.
It is described below with the conventional steps of nephro-dynamic imaging drug injection：
1st, need first to carry out establishing venous access with the No.1 syringe for pumping physiological saline；
2nd, clearly establish venous access success after, first one of tubule syringe needle close to syringe is bent, then
No.1 syringe is unpluged with tubule syringe needle, changes No. two syringes, " bullet formula " injection medicine, while needs another work people
Member's start carries out dynamic acquisition renal blood flow and blood pool phase；
3rd, in order to which the medicine in tubule syringe needle is also injected into patient's body, it is necessary to again tubule syringe needle doubling, 2 are unpluged
Number syringe, changes No. 1 syringe；
4th, when sometimes patient has uronephrosis, it is also necessary in injection process, one needle tubing for pumping furosemide of prepare more, upper
, it is necessary to increase a step of step replaces furosemide needle tubing before stating the 3rd step.
There are problems with during operation：（1）Various medicines are colourless, in order to ensure that injection is correct, it is necessary to use marker pen
It is marked on needle tubing, adds task complexity, and easily take needle tubing by mistake.（2）, it is necessary to repeatedly bend in injection process
Tubule syringe needle, replaces the needle tubing equipped with different pharmaceutical, and during bending, the venous access established is easily extracted blood vessel,
Injection is caused to fail；And in replacement process, the outflow of the materials such as medicine is also inevitably had, may so cause to radiate
Property medicine contaminating examination bed, operating personnel's hand, patient's clothing etc..（3）Nephro-dynamic imaging, in order to ensure checks fie image quality, needs
Ballet Shop is wanted to inject, but during repeatedly syringe is replaced, it is desirable to staff is very skilled, even if in this way, also not
It is evitable to extend injection time, it can not ensure efficient Ballet Shop injection.
Some medicines in injection, if using needle tubing direct injection, the part of venipuncture puncture it is not very successful or
After person's intravenous injection medicine, compressing not in time, the time not enough or other reasons, the residual of injection site imaging medicament can be caused
Stay, so in imaging, analysis and the quality of image can be influenced；Injection site medicine has residual, will cause to enter internal
Dose reduce, equally can also influence picture quality.

Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
As shown in Figs. 1-3, a kind of syringe, including syringe cylinder 1 and plunger part 2 with dispensing end 5, syringe cylinder
Syringe inner cylinder 3 is cased with 1, syringe inner cylinder 3 is slidably connected with syringe cylinder 1 and plunger part 2, by pulling syringe
Inner cylinder 3 can be drawn fluid into syringe cylinder 1, and 3 bottom of syringe inner cylinder is equipped with through hole, by pulling plunger part 2 to incite somebody to action
Liquid is pumped into syringe inner cylinder 3；3 bottom of syringe inner cylinder is equipped with through hole, which connects with dispensing end 5.Syringe inner cylinder 3
Rotatable protective device 6 is equipped with, the through hole of 3 bottom of syringe inner cylinder can be blocked or expose by rotating protective device 6, from
And control the connected state of through hole and dispensing end 5.
The position of 3 bottom through-hole of syringe inner cylinder is unrestricted, its position can be blocked completely easy to protective device.
Therefore, through hole can be arranged on non-central location.
Mark is equipped with protective device 6 and syringe inner cylinder 3, can learn whether protective device 6 blocks note by mark
The through hole of 3 bottom of emitter inner cylinder.Mark can be line of weakness, can also be smeared in protective device 6 and syringe inner cylinder 3 red
Color marker, when the red-label of protective device 6 is opposite with the red-label of syringe inner cylinder 3, then it represents that protective device 6 is not kept off
Firmly through hole.Certainly, other colors can be also set or using other modes, have the function that mark.
When extracting liquid, rotate protective device 6 and expose the through hole of 3 bottom of syringe inner cylinder, pull plunger part 2, liquid
The through hole that body flows through 3 bottom of syringe inner cylinder by dispensing end 5 enters in syringe inner cylinder 3；Syringe inner cylinder 3 is hydraulically full
Afterwards, by rotating protective device 6, through hole is blocked, avoids the outflow of liquid.
Syringe inner cylinder 3 is pulled to be pumped into liquid in syringe cylinder 1, when pulling syringe inner cylinder 3, protective device 6 also with
Movement, and be to block through hole all the time.
It is opposite with extracting liquid step when injecting liquid.When needing to inject the liquid in syringe inner cylinder 3, need to rotate
Protective device 6, through hole is exposed；Otherwise, protective device 6 is not rotated.
Protective device 6 can be the empty cylinder of bottom opening, and empty cylinder can be set in outside syringe inner cylinder 3, or is sleeved on syringe
In inner cylinder 3；When its opening is connected with the through hole of 3 bottom of syringe inner cylinder, the inflow of liquid and stream in syringe inner cylinder 3 can be made
Go out.
Due to that without syringe is needed to change, uninterrupted, the orderly injection of different pharmaceutical can be completed using same syringe, is kept away
Exempted from because operate it is unskilled, or it is highly difficult operation or patient be not easy coordinate when needle tubing extract the problem of；Improve injection
Success rate.
Certainly, according to actual use situation, at least one syringe inner cylinder 3, each note can be arranged with syringe cylinder 1
Emitter inner cylinder 3 is mutually socketed, and forms more tube-in-tube structures, it is possible to achieve the pumping of multi-medicament；Two adjacent syringe inner cylinders 3
Between, it is set in outer syringe inner cylinder 3 and extracts and inject liquid by the syringe inner cylinder 3 being set in it for it.And
Rotatable protective device 6 is equipped with each syringe inner cylinder 3, each syringe inner cylinder 3 is formed relatively independent sky
Between, avoid the mixing between medicine.
Catch 4 is equipped with syringe cylinder 1, syringe inner cylinder 3 and empty cylinder, can be facilitated in pull syringe by catch 4
Cylinder 3 and the empty cylinder of rotation；Therefore, the position of catch 4 can be designed according to actual conditions, its position is in order to based on people's use.Gear
The quantity of piece 4 is also unrestricted.
The preferred embodiment only to the utility model is explained in detail above, but the utility model be not limited to it is above-mentioned
Embodiment, within the knowledge of a person skilled in the art, can also not depart from the utility model aims
