At.It can be fixed on wall, ceiling, instrument table, cart and movable stand.High pressure enhanced CT angiographic procedure at present
In, contrast agent is sucked in high pressure injector syringe generally by the mode of suction pipe, angiography catheter is then reconnected, works as high pressure
When the contrast agent of injector syringe is finished, angiography catheter need to be removed, then suck contrast agent with suction pipe, in angiographic procedure very not
It is convenient.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of high pressure injectors, for solving high pressure injector syringe
Contrast agent need to remove angiography catheter when being finished, then suck contrast agent with suction pipe, it is very inconvenient in angiographic procedure to ask
Topic.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
A kind of high pressure injector, including syringe, the syringe have syringe needle, and piston and guide rod are equipped in syringe, and piston will
Syringe is separated into the first cavity and the second cavity, and guide rod is located in the second cavity, and guide rod is connect with piston, separate in syringe
Guide sleeve is fixedly connected in syringe needle one end, guide rod is arranged in guide sleeve, seals, lead by multi-turn sealing ring between guide rod and guide sleeve
Bar is fixedly connected far from piston one end with one piece of baffle, is cased with plastic telescopic pipe outside guide rod, telescoping tube both ends respectively with baffle
It is fixedly connected with syringe nozzle；It further include flexible tonic bag, tonic bag is connected to the second cavity by hose, is equipped on piston
Multiple check valves are equipped with the first valve on hose.
It is communicated with tonic pipe on tonic bag, the second valve is installed on tonic pipe.
It is equipped in syringe between syringe needle and piston and is fixedly connected with a block baffle, through-hole is offered on baffle,
Through-hole is equipped with one piece of cover plate, cover plate one end and panel hinge towards syringe needle end face.
The flexibility tonic bag is made of using polypropylene material.
The beneficial effects of the utility model are: piston will while piston pushes the contrast agent in the cavity of syringe side
Spare contrast agent in tonic bag is pumped into piston other side cavity, and when retracting piston, syringe is again filled with contrast agent,
It realizes the lasting supplement to contrast agent, and then does not have to remove angiography catheter, use safe ready.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing:
Fig. 1 is the schematic diagram of the section structure of the utility model.
Fig. 2 is the partial enlargement structural representation of the utility model.
In figure: syringe 1, piston 2, guide sleeve 4, guide rod 5, telescoping tube 6, tonic bag 7, baffle 8, the first cavity 11, second are empty
Chamber 12, syringe needle 13, check valve 21, baffle 51, the first valve 71, the second valve 72, hose 73, tonic pipe 74, cover plate 81.
Specific embodiment
As illustrated in fig. 1 and 2, a kind of high pressure injector, including syringe 1, the syringe 1 have syringe needle 13, are equipped in syringe 1
Syringe 1 is separated into the first cavity 11 and the second cavity 12 by piston 2 and guide rod 5, piston 2, and guide rod 5 is located in the second cavity 12,
5 one end of guide rod is connect with piston 2, is arranged far from guide sleeve 4, guide rod 5 is fixedly connected in 13 one end of syringe needle in guide sleeve 4 in syringe 1
It is interior, it is sealed between guide rod 5 and guide sleeve 4 by multi-turn sealing ring, guide rod 5 is fixedly connected far from 2 one end of piston with one piece of baffle 51,
Plastic telescopic pipe 6 is cased with outside guide rod 5,6 both ends of telescoping tube are fixedly connected with baffle 51 and 1 nozzle of syringe respectively；It further include soft
Property tonic bag 7, tonic bag 7 is connected to by hose 73 with the second cavity 12, on the piston 2 equipped with multiple check valves 21, in hose
First valve 71 is installed on 73.
The application method of the utility model are as follows: after high pressure injector is installed in injector, injector pushes guide rod 5 to move
Dynamic, guide rod 5 is exported the contrast agent in the first cavity 11 by syringe needle 13 by piston 2, at the same time, can open the first valve
71, the contrast agent in tonic bag 7 is entered in the second cavity 12 by hose 73, and plastic telescopic pipe 6 is compressed, when the first cavity
After contrast agent push in 11, the first valve 71 is closed, guide rod 5 is retracted, and the contrast agent in the second cavity 12 passes through each list
It being entered in the first cavity 11 to valve 21, plastic telescopic pipe 6 is elongated, thus can be with biphasic injection contrast agent, and then it can be with
Supplement to contrast agent can be completed without removing syringe 1；On the other hand, when twitching guide rod 5 back and forth, guide rod 5 can be moulded
Expect that telescoping tube 6 surrounds, effectively avoids avoiding contrast agent from being contaminated in extraneous dust contamination to guide rod 5；On the other hand, soft
Property tonic bag 7 can be shunk with the supplement of contrast agent, prevent its from forming negative pressure, it is ensured that contrast agent can smoothly enter into second
Cavity 12.
It is communicated with tonic pipe 74 on tonic bag 7, the second valve 72 is installed on tonic pipe 74.When flexible tonic bag 7
In contrast agent be finished after, medical fluid can will be filled into tonic bag 7 by tonic pipe 74.
