A kind of high pressure injector inhales medicine safety detection method automatically, it is characterised in that the following steps are included:
Step1: injection device (8) carries out suction medicine, connect syringe with infusion bag (4) by multichannel electrically-controlled valve (1), with
The interface channel of conduit (3) is closed, and inhaling medicine is the piston time that injection device makes syringe by control piston motion braking system
Contracting, when the conduit between syringe and infusion bag is twisted together or blocks, due to occurring vacuum, control piston motion braking in syringe
The torsion of motor output in system can be very big, thus counter to push away, when injection device inhales medicine, by the torsion for judging motor output
Judge whether vacuum occur in syringe.
Step2: the processing of anti-vacuum: syringe judges motor torsion when bouncing back, and reminds user to check needle tubing when torsion is excessive
Whether block or twist together, and terminate motor movement, not so motor moves to always retraction and completes and (inhale medicine to complete).
Step3: motor (21) is positive, rotates backward, and motor (21) will drive small pulley (22) rotation when rotating, and then leads to
It crosses belt (23) and drives feed screw nut (24) rotation, push rod (13) is connect with feed screw nut (24), and then the circumference of feed screw nut
Conversion of motion is the linear motion (advance and retreat) of push rod.
Step4: when push rod forward impelling, claw (14) can automatic pinch in, the front end of push rod and piston contact and forward
Push piston.When push rod bounces back, claw can be stretched, and hook piston and bounce back backward with piston.
It is more acurrate the present invention generally relates to the injecting systems of the supply fluid during medical diagnosis and treatment procedure
Ground is said, more precisely, is related to for injecting contrast agent and flushing liquor, to cooperate the high-pressure injection system of radiography.

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The present invention provides a kind of drug dose calibrating installation, is able to solve the prior art poor, effect of manually preparing dose accuracy
Rate is low, the high problem of human cost.
Specific implementation of the invention is described in detail below in conjunction with specific embodiment.
If figure (1) show the high-pressure injection system bubble testing mechanism schematic diagram of redundancy, include: multichannel electrically-controlled valve 1,
2 conduit 3 of air bubble sensor, infusion bag 4, liquid level sensor 5, put inside syringe protective cover 6 syringe, bracket 7, injection device 8,
Hand control switch 9, fluid control ancillary equipment 10.
The syringe of 6 the inside of syringe protective cover is connect by conduit with multichannel electrically-controlled valve 1, using multichannel electrically-controlled valve 1
It is connect respectively with infusion bag 4, patient's (being not drawn into figure).
When injection device 8 carries out suction medicine, it connect syringe with infusion bag 4 by multichannel electrically-controlled valve 1, the company with conduit 3
Road is connected to be closed.Inhaling medicine, to be injection device make the piston of syringe bounce back by control piston motion braking system.When syringe with
When conduit between infusion bag is twisted together or blocked, due to occurring vacuum in syringe, the electricity in piston motion braking system is controlled
The torsion of machine output can be very big.Thus counter to push away, when injection device inhales medicine, by judging that the torsion of motor output judges in syringe
Whether vacuum is occurred.
For the processing logic flow of anti-vacuum as shown in figure (2), syringe judges motor torsion when bouncing back, and reminds when torsion is excessive
User checks whether needle tubing blocks or twist together, and terminates motor movement.Not so motor moves to always retraction and completes (it is complete to inhale medicine
At).
If figure (3) show the primary structure of control piston motion braking system, syringe protective cover has been removed.Motor
21 forward directions rotate backward, and motor 21 will drive the rotation of small pulley 22 when rotating, and then drive the rotation of feed screw nut 24 by belt 23
Turn, push rod 13 connect with feed screw nut 24, and then the circular motion of feed screw nut be converted into push rod linear motion (advance and after
It moves back).
As figure (4) show push rod 13 and 15 connection structure of piston.When push rod forward impelling, claw 14 can be retracted automatically
It goes, the front end of push rod and piston contact simultaneously push forward piston.When push rod bounces back, claw can be stretched, and hook piston and drive
Piston bounces back backward.
The present invention provides a kind of high pressure injector and inhales medicine safety detection method automatically, solves the injection dress of conventional syringe
When setting that disposable contrast agent needle tubing is by kink or obstruction during inhaling medicine, syringe is caused to vacuumize, and medical staff is not yet
The problem of easily realizing, excludes security risk in time.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
