Abstract
The invention discloses an injection finishing control method of a syringe injection pump. The method comprises the following steps that a computer control system is used for controlling the running of a stepping motor; the stepping motor drives a screw rod to rotate through a reduction gearbox; the rotation of the screw rod drives a screw rod nut to axially and linearly move so as to drive a power rod and a push rod to linearly move synchronously; each position in the moving procedure of the push rod corresponds to each displacement signal of a linear displacement sensor, the positions where the push rod is positioned when the injection of the syringe injection pump is finished and is to be finished are exactly defined in advance; and when the push rod moves to the defined positions, the computer control system gives an alarm and prompts. By the method disclosed by the invention, the alarming function when the injection of the injection pump is finished can be realized under different conditions; even though the tail part of a syringe is relatively small and the amount of the injection is less, the alarming function can also be realized when the injection is finished and is to be finished.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of syringe is injected caliberating device and the scaling method thereof of pump capacity scale.
Background technology
Syringe is injected pump need to have a signal feedback that stops to control system when end of run; run to a specific position control system and send and be about to inject complete information or shutdown so that syringe is injected the propulsive mechanism of pump, just to control and to arrange one in pump and inject complete recognition device syringe is injected in order to realize shutting down.
At present, the complete control program of injection of using syringe to inject pump is at the terminal position that propulsion system is moved, a position detecting switch to be set mostly, and this switch can be Hall sense switch or mechanical switch or photoswitch.This scheme is that a switching point is set, the certain distance L 0 of reruning after the propulsive mechanism that promotes push rod runs to this switching point is just sent and is about to inject complete warning message, the certain distance L 1 of reruning after propulsion system runs to this switching point is just sent the complete warning message of injection, L1〉L0.
The value of tail dimension L of injecting pump push rod due to the syringe of each producer, all size is different, therefore the value of above-mentioned L1, L0 must greater than Lmax(namely this syringe inject the maximum of tail dimension L in all push rods that pump is suitable for), be L1〉L0〉Lmax, inject complete or be about to inject complete otherwise just can't detect.The position of alarm point generally is taken near Lmax, when the less and amount of liquid of the tail dimension L of the injector push-rod that uses is less, just may have the problem that realizes not that injection is complete or be about to inject complete warning.
Summary of the invention
The present invention seeks to: for the problems referred to above, the invention provides a kind of syringe and inject infusion and shoot away complete control method, the method can be guaranteed to inject in all cases infusion and shoot away the realization of finishing and being about to inject complete alarm function.

it is characterized in that: described propulsive mechanism comprises the motor that power is provided, control the computer control system of this motor running, the screw mandrel that is arranged in parallel with described push rod, and the power rail that is arranged in parallel with this screw mandrel, wherein, described motor is connected with described screw rod transmission by reduction box, on described screw mandrel, cover has the feed screw nut of threaded engagement with it, described power rail one end is connected with described feed screw nut, the other end is connected with described push rod, be equipped with in described pump case one can the described power rail run location of Real-Time Monitoring linear displacement transducer, and this linear displacement transducer is electrically connected to described computer control system,
Described computer control system is controlled described motor running, motor drives the screw mandrel rotation by reduction box, screw mandrel rotarily drive feed screw nut's axial linear movement, and then drive power rail and the push rod synchronous linear moves, a displacement signal of each the position line correspondence displacement transducer of push rod in running, in advance syringe is injected infusion and shoot away when finishing and accurate calibration is carried out in the push rod position that is about to inject when complete, sent by computer control system when push rod runs to the position of demarcating and report to the police and point out.
As preferably, described linear displacement transducer is arranged in described pump case by the displacement transducer Connection Block.
Advantage of the present invention is: syringe of the present invention is injected pump can guarantee to inject in all cases complete realization with being about to inject complete alarm function, even the tail dimension of syringe is less, when the amount of injection is less, also can guarantees to inject complete and and be about to inject the realization of complete alarm function.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is the appearance figure that in the embodiment of the present invention, syringe is injected pump;
Fig. 2 is that the E-E of Fig. 1 is to cutaway view;
Fig. 3 is that the F-F of Fig. 2 is to cutaway view;
Wherein: 1-pump case, 2-syringe, 3-push rod, 4-propulsive mechanism, 41-motor, 43-reduction box, 44-screw mandrel, 45-feed screw nut, 46-power rail, 5-linear displacement transducer, 6-displacement transducer Connection Block.
The specific embodiment
As shown in Figure 1, the syringe of the present embodiment is injected pump and is comprised: pump case 1, be fixedly installed on described pump case 1 inside, can keep in the graduation mark that is carved with the expression capacity on the barrel of this syringe of syringe 2(of injection in it, this containing mark line has just been carved by manufacturer in the syringe manufacture process), be slidably arranged in the push rod 3 in described syringe 2, and be used for driving the propulsive mechanism 4 that described push rod 3 is injected away in the axial linear slide operation of described syringe 1, with the injection of keeping in syringe.
As shown in Figures 2 and 3, described propulsive mechanism 4 comprise motor 41 that power is provided, control the computer control system (not shown) of these motor 41 runnings, the screw mandrel 44 that is arranged in parallel with described push rod 3 and the power rail 46 that is arranged in parallel with this screw mandrel 44.Wherein, motor 41 is in transmission connection by reduction box 43 and screw mandrel 44, and on screw mandrel 44, cover has the feed screw nut 45 of threaded engagement with it, and power rail 46 1 ends are connected with the feed screw nut, and the other end is connected with push rod 3.Wherein, motor 41, reduction box 43, screw mandrel 44 and feed screw nut 45 all are arranged on the inside of described pump case 1, disturb the normal operation of propulsive mechanism 4 to reduce extraneous factor.And, this example in described pump case 1 by displacement transducer Connection Block 6 be equipped with one can described push rod 3 run locations of Real-Time Monitoring linear displacement transducer 5(straight line displacement sensor 5 have fixed part and movable part, wherein movable part is arranged on described power rail 46, when power rail moves, movable part is synchronized with the movement thereupon), this linear displacement transducer 5 is electrically connected to described computer control system.
