Compared with prior art, the advantages and positive effects of the utility model are as follows: in use, rotation driven by rotary disc screw rod turns
Dynamic, screw rod rotation is moved with piston to the direction of turntable, and piston is moved to top, backs out sealing cover, contrast agent is led to
It crosses liquid inlet joint to pour into injection tube, tightens sealing cover, liquid inlet joint opening upwards go out the orifice of contrast agent injection needle
Liquid head, rotates backward the rotation of driven by rotary disc screw rod, and screw rod rotation pushes piston to squeeze the contrast agent in injection tube to reverse movement
Enter patient's body through liqiud outlet head and contrast agent injection needle, is played in the sliding slot of the guide ledges insertion injection tube inner wall on piston
Guiding role injects speed for what piston promotion same displacement can easier control contrast agent by screw rod per revolution
Degree, screw rod rotation is disc-rotated, since cylindrical slider is arranged in curve chute, as disk rotational drives each circle
Cylindrical slide is in the gliding in tracks of curve chute, simultaneously because cylindrical slider is fixed in rectangular block, rectangular block limit exists
In trapezoidal slide block, therefore cylindrical slider drives rectangular block to move back and forth under the limitation of corresponding trapezoidal slide block, and rectangular block is mobile
Corresponding plectrum is driven to move back and forth, plectrum moves back and forth the contrast agent in agitation injection tube, prevents because bolus administration of contrast agent is excessively slow
And the phenomenon that causing contrast agent Density inhomogeneity or precipitating.This puncture outfit can be realized in a rotating manner that bolus administration of contrast agent is simultaneously
Contrast agent is stirred in bolus infusion processes, prevents contrast agent precipitating or density unevenness.

Specific embodiment
With reference to the accompanying drawing, a specific embodiment of the utility model is described in detail, it is to be understood that this
The protection scope of utility model is not limited by the specific implementation.
As shown in Fig. 1-Fig. 7, the utility model includes injection tube 5, and liquid inlet joint 2 is fixed on the injection tube 5, described
One end of injection tube 5 is equipped with liqiud outlet head 7, and turntable 3 is fixed on 4 one end of screw rod, and the 4 of the screw rod hingedly pass through the injection tube 5
The other end and end be hinged on the leading inside of the injection tube 5, piston 9 is threaded on the screw rod 4, the piston
Two guide ledges 10 symmetrically fixed are embedded in the symmetrical sliding slot 8 that 5 inner wall of injection tube is equipped in 9 cambered surface, disk
11 center is fixed on the end of the screw rod 4, and the side of the disk 11 is equipped with the curve chute 18 of closure, and the curve is sliding
Slot 18 is embedded with one group of cylindrical slider 16, and each cylindrical slider 16 is respectively fixedly connected with rectangular block 12, each described
The two sides of rectangular block 12 are respectively fixed with one group of evenly arranged plectrum 13, are respectively equipped with ladder on the downside of each rectangular block 12
Shape sliding slot 14 is respectively equipped with trapezoidal slide block 17 in each ladder chute 14, and each trapezoidal slide block 17 passes through company respectively
Block 15 is fixedly connected in 5 front inner wall of injection tube.
Handle 6 is fixed on the injection tube 5.
Sealing cover 1 has been threadedly engaged in the liquid inlet joint 2.
Curve chute 18 is irregular symmetrical circular orbit, so that during curve chute 18 follows disk 11 to rotate
Cylindrical slider 16 can be pushed to move back and forth, and because cylindrical slider 16 is fixedly connected with rectangular block 12, rectangular block 12 due to
The position-limiting action of trapezoidal slide block 17, so that rectangular block 12 is moved back and forth along trapezoidal slide block 17.The track of curve chute 18 pushes circle
The mobile displacement of cylindrical slide 16 is appropriate, and rectangular block 12 will not be made to be detached from the limitation of trapezoidal slide block 17.
The workflow of the utility model are as follows: in use, rotation turntable 3 drives screw rod 4 to rotate, the rotation of screw rod 4, which drives, lives
Plug 9 is moved to the direction of turntable 3, and piston 9 is moved to top, backs out sealing cover 1, and contrast agent is filled by liquid inlet joint 2
Enter in injection tube 5, tightens sealing cover 1,2 opening upwards of liquid inlet joint, by the orifice liqiud outlet head 7 of contrast agent injection needle, instead
Screw rod 4 is driven to rotate to rotation turntable 3, the rotation of screw rod 4 pushes piston 9 to squeeze the contrast agent warp in injection tube 5 to reverse movement
Liqiud outlet head 7 and contrast agent injection needle enter patient's body, and the guide ledges 10 on piston 9 are embedded in the sliding slot 8 of 5 inner wall of injection tube
Guiding role is played, the promotion of piston 9 same displacement can easier be controlled by pushing away for contrast agent by 4 per revolution of screw rod
Speed is infused, the rotation of screw rod 4 drives disk 11 to rotate, since cylindrical slider 16 is arranged in curve chute 18, with disk 11
Rotation drives each cylindrical slider 16 in the gliding in tracks of curve chute 18, simultaneously because cylindrical slider 16 is fixed on square
In shape block 12, rectangular block 12 is limited in trapezoidal slide block 17, therefore cylindrical slider 16 drives rectangular block 12 in the trapezoidal cunning of correspondence
It is moved back and forth under the limitation of block 17, rectangular block 12 is mobile to drive corresponding plectrum 13 to move back and forth, and plectrum 13 moves back and forth agitation
Contrast agent in injection tube 5, prevent because bolus administration of contrast agent is excessively slow cause contrast agent Density inhomogeneity or precipitating the phenomenon that.
Disclosed above is only a specific embodiment of the utility model, and still, the utility model is not limited to this,
The changes that any person skilled in the art can think of should all fall into the protection scope of the utility model.
