The reflux of contrast agent, while the corresponding micro one-way valve 504 of each aspirating needle 502 and a conduit are enough prevented, that is, shares six
A conduit is pierced by from the inside of sleeve 505.
The lower end surface of needle tubing storage unit case 1 is provided with the foot pad of different-thickness, and the foot pad close to 103 side of regulating tank is high
Degree is greater than the height close to 106 side foot pad of mounting groove.Needle tubing is set to be put into slot 101 and needle tubing discharge slot 107 and ground in certain
Angle, due to gravity when being put into, needle tubing 4 slides into holding tank 102 automatically, when discharge, slot 107 can also be discharged from needle tubing and skid off.
The system carries out contrast agent injection and realizes the process of needle tubing 4 and conduit replaced automatically:
The installation of S1, needle tubing 4: the needle tubing 4 after multiple heating is successively filled in into needle tubing in the same direction and is put into slot 101, by identical
The needle tubing of shape is put into slot 101 and needle tubing 4, realize it is simple and fast be put into needle tubing 4, so that needle tubing 4 is slid into holding tank 102 and stack
Together, and to needle tubing 4 it keeps the temperature.
The connection of S2, needle tubing 4 and conduit: the first electrical retractor 201 of control starts and extends, and makes pushing component 203
Across actuated syringes unit link slot 105, pushing component 203 pushes the needle tubing 4 of bottom to adjust component 5 to aspirating needle and moves,
Until aspirating needle 502 is pierced into fluid hole 410, realize that needle tubing 4 adjusts component 5 with aspirating needle and is connected to, i.e., needle tubing 4 and conduit are completed
Connection；
S3, air in pipeline is excluded: due to the corresponding first electric expansion dress of two actuated syringes units of injection module
Set 201 it is inactive when, mandril 2033 is on the no longer same straight line of corresponding first through hole 404, and magnetic posts 409 will be longer than grafting set
408, therefore one end can stretch out liquid storage box 401, therefore when needle tubing 4 adjusts component 5 with aspirating needle and is connected to, magnetic shaft 2032 can be first
It is contradicted with magnetic posts 409, pushes needle tubing 4 to adjust component 5 to aspirating needle and move, until aspirating needle 502 is pierced into fluid hole 410,
At this time due to needle tubing 4 and pipeline connection, continue movement magnetic shaft 2032 can make piston plate 407 from the left end of liquid storage box 401 to
Right end moves a distance, until mandril 2033 and 4 outer wall of needle tubing contradict, the first electrical retractor 201 no longer extends at this time,
A part of contrast agent is discharged piston plate 407 from fluid hole 410, flows into aspirating needle 502, after being then passed through micro one-way valve 504,
So that contrast agent is filled conduit, completes the discharge of circuit air；
The injection of S4, contrast agent: the needle tubing 4 of two 1 bottoms of needle tubing storage unit case is connected to aspirating needle and adjusts component 5
Afterwards, select any one needle tubing storage unit case 1 as main dispensing end, another needle tubing storage unit case 1 is used as ready for injection
End, first controls the first electrical retractor 201 and shortens to the left, so that magnetic shaft 2032 is extracted liquid storage box 401 out, then control main dispensing end
Corresponding first stepper motor 202 turns an angle, and such as rotates clockwise 45 °, keeps mandril 2033 and first through hole 404 total
Line controls the first electrical retractor 201 again at this time and continues to extend, and magnetic shaft 2032 and mandril 2033 are each passed through second at this time
Through-hole 405 and first through hole 404, and be connected to magnetic posts 409 and grafting set 408 in, the first electrical retractor 201 after
It is continuous that piston plate 407 is pushed to move to the right, the contrast agent on 407 right side of piston plate is discharged from fluid hole 410, flows into aspirating needle
In 502, after being then passed through micro one-way valve 504, inflow catheter eventually arrives at the internal of patient；
The replacement of S5, needle tubing 4: the step of passing through S1-S3 is connected to the needle tubing 4 at ready for injection end with conduit, when main injection
When 4 surplus of needle tubing of end connection is less than preset value, the needle tubing if specification is 10ml then stops when the amount of remaining contrast agent is 1ml
Only main dispensing end injection, and the step of according to S4, use ready for injection end instead and inject to patient；It is infused at ready for injection end
While penetrating, the first electrical retractor 201 of main dispensing end shortens, until magnetic shaft 2032 all takes in actuated syringes unit
In shell 2, the needle tubing 4 of bottom is located in actuated syringes unit link slot 105 at this time, and aspirating needle is made to adjust component 5 and be finished
Needle tubing 4 separate, while magnetic shaft 2032 is separated with magnetic posts 409, such as use magnetic shaft 2032 for magnet plunger, pass through control it is electric
Stream is realized magnetic shaft 2032 and the absorption of magnetic posts 409 and is separated, while the not used needle tubing 4 in top is fallen, and controls the at this time
The elongation of two electrical retractors 601, the push plate 602 positioned at 4 lower section of needle tubing to be discharged push up needle tubing 4 to be discharged to needle
Pipe is discharged in slot 107, and needle tubing 4 to be discharged is discharged along needle tubing discharge slot 107, completes the replacement of needle tubing 4；
