In the machine, a step motor drives a screw rod in a decelerating mode and opens and closes a nut to drive a pushing block to do straight line propelling motion; a self-control injection circuit is composed of a three-position driver plate type switch control CP pulse generator, a three-phase six-beat distributor, a pulse amplifier, a limiting circuit, an overloading circuit and an early warning circuit. The machine can simultaneously carry out the speed division regulation and the path division regulation of more than two kinds of medicine, different flow quantity and different injection velocity. The utility model has the advantages of convenient operation, portability and good effect through clinical application, and is suitable for carrying out micro transfusion in the medical care of chest surgery, normal surgery, internal medicine, tumour, newborn, etc.
Description
This utility model relates to a kind of medical department that is used for, and the automatic control injector of injection trace drug liquid belongs to medical equipment.
Over surplus in the of nearly ten year, because to the applying of metabolic research and hemodynamics bedside monitoring technology, use the vasodilation medicine clinically more and new positive inotropic medicament has been obtained good result.But in application, because these drug effects are fast, the persistent period is short, especially dopamine, this drug dose difference acts on also differently, plays vasorelaxation action when 5g/kg/min, then play the vasoconstriction effect when surpassing 15g/kg/min, bad as flow-control, effect is opposite fully.Therefore, require speed permanent steady when using these medicines, not so accurate measurement easily causes blood pressure to rise and fall significantly, brings life danger to the patient.
At present domestic in the injection of vein heavy dose, the invention of the existing syringe of control automatically is born, but still adopts traditional work on the vein trace instils, and does not still have desirable device.Also there are the following problems simultaneously:
(1) flow is wayward, can't accurately regulate, and the transfusion fluctuation is big.
(2) fluid volume computation error is also big.
(3) can not use the different flow of medicine more than two kinds, and the injecting method that can accurately regulate at any time respectively.
Task of the present utility model is the weak point that solves above-mentioned existence, provides a kind of when injecting trace drug liquid clinically, both accurate, constant speed transfusion, can carry out different pharmaceutical liquid more than two kinds simultaneously respectively again, different flow, adjustable multiple tracks automatic control injector.Flow is from 0.1ml/h-99.9ml/h; the adjusting fineness is 0.1ml; during injection as taking place that syringe needle blocks and other reason when causing that syringe jacking block thrust surpasses 12kg; the automatic control machine promptly can send sound and light alarm; and shut down simultaneously; when transfusion during to last 3ml liquid, promptly send and be interrupted the indication of pre-alarm sound, report to the police with long several light when injection finishes and shut down.
This utility model, drives jacking block pushing syringe plunger and injects through deceleration screw mandrel and clasp nut by motor.Automatic control injector circuit theory by three dial-type on-off control CP pulse generators, three-phase six-beat allotter, pulse amplifier and spacing, overload, early warning circuit is formed and finish automatic control injection task.
This utility model specifically describes in conjunction with following enforcement.
Fig. 1 is this utility model sketch map.
Fig. 2 is this utility model cutaway view.
Fig. 3 is this utility model schematic diagram.
Fig. 4 is this utility model circuit theory diagrams.
According to shown in Figure 2, suction there is syringe (1) device of pharmaceutical liquid on the cylinder seat (2) of automatic control body, the automatic control micro-injection machine adopts motor (3) as power source, through i=50 reduction box (4), with outputting axial power through gear Z1(5), Z2(6) pass to screw mandrel (7), screw mandrel (7) drives the clasp nut (9) that links to each other with jacking block (8), thereby make rotatablely moving of motor (3) change the rectilinear motion of jacking block (8) into, syringe plunger motion on the left of jacking block (8) motion promotion is fixed on guide plate (10), thus reach the purpose that the automatic control constant speed is injected.The purpose that the reduction box (4) of i=50 is set is in order to improve stepper (3) rotating speed, to avoid motor (3) in low frequency ranges work, this moment motor shaft pulsation clearly.When jacking block (8) moved to early warning switch (11), touch panel (12) touched early warning switch (11), sent early warning on the machine and was interrupted sound and light signal.When touch panel (12) touched spacing alarm switch (13), early warning signal disappeared, and motor (3) quits work, and sent and injected the long sound and light alarm signal continuously that finishes.When jacking block (8) is obstructed, and back pressure spring (14) was in the promotion lower compression of screw mandrel (7) and thimble (15) when resistance surpassed 12kg, thimble (15) is made microdisplacement, this microdisplacement is through lever (16) and overload warning switch (17), cut off motor (3) power supply, and open sound light alarming circuit simultaneously and do the indication of reporting to the police.
After a shot finishes, with depression bar (18) depress, clasp nut breaks away from screw mandrel (7), promptly available hands moves to guide plate (10) left side starting point with jacking block (8), injects preparation next time.
According to Fig. 3, shown in Figure 4, the motor speed governing, driving and warning circuit principle are, by three decimal scale dial-type on-off control CP pulse generators (19) output pulse signal, behind three-phase six-beat pulsqe distributor (20) and pulse amplifier (21), drive motor rotation, by the R1-R29 resistance in the dial switch change pulse generator, can reach 999 kinds of different speed, when overload warning (17 ') spacing alarm (13 ') two switches touch respectively, switch cuts off the power supply of (19) and (20), and connects sound light alarming circuit (22) simultaneously.When touching early warning switch (11 '), early warning circuit (23) promptly does to be interrupted acousto-optic early warning indication.
According to Fig. 2, Fig. 3, Fig. 4 is comprehensively described, this utility model is the device of a kind of automatic control multiple tracks micro-injection, it is to be power source with motor (3), drive reduction box (4) final gear (5) (6), screw mandrel (7), nut (9) is formed drive system, nut (9) links to each other with jacking block (8), top fast (8) left side cylinder seats (2) are gone up fixedly syringe (1), the shaft rear end of screw mandrel (7) is put a thimble (15), back pressure spring (14), being equipped with lever between thimble (15) and overload warning switch (17 ') links, jacking block (8) walks to terminal point and puts spacing alarm switch (13 '), is disposing early warning switch (11) for 3 millimeters less than terminal point.
