Description
Technical field
Medical instruments field is the utility model is related to, more particularly to a kind of fixed-quantity injector.
Background technology
The syringe that medical treatment at present uses can not be according to clinical requirement dosed administration, and the needing of needle tube type syringe uses finger
Clamp and squeeze and push away, it is necessary to which larger exerts oneself.Calibrated shot needs to be quantified come positioning retainer ring on mobile putter with hand, and one
Secondary positioning can only calibrated shot once, if necessary to continuously carry out once quantitative injection again, it is necessary to moved once with hand again
Positioning retainer ring, so continuously continual a calibrated shot can not be carried out again.In radiography operation, doctor's calibrated shot is made
During shadow agent, be frequently not once, radiography according to the observation image situation, it is necessary to which continuously calibrated shot is one or many again makes
Shadow agent, until reaching optimal contrasting effects.It is very inconvenient using in general syringe, it is impossible to realize determining for continuous several times
Amount injection, and injection medicine is usually needed in medical field, when in use, different dosages can play completely these medicines
Different effects.Such as：Dopamine, the medicine can play angiectatic effect in 5g/kg/min；And more than 15g/kg/
During min, then vasoconstrictive effect can be played.Two kinds of drug effects completely contradicted, life-and-death effect can be played to patient.Cause
This, and existing syringe, injected mostly using manual operation, it is necessary to which manual control drug flux, control are got up very
Difficulty, flow is often unstable, and fluctuation is very big, it is easy to patient is produced adverse reaction, or even patients ' lives can be caused
It is dangerous.
Utility model content
Technical problem to be solved in the utility model be solve current syringe can not dosed administration, and manual control
Injection can not ensure the accuracy of injection volume.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of fixed-quantity injector, including housing and note
Emitter, the syringe include syringe shell and the push rod stretched into from syringe shell one end in syringe shell, and the push rod stretches into
One end in syringe shell is provided with piston, and the push rod promotes piston to be slided in syringe shell, and the syringe shell is another
End is provided with injection head, and described syringe one end is placed in housing；Motor and motor power are provided with the housing；It is described to push away
Dentation is arranged at intervals with bar；The gear being engaged with the dentation is provided with the motor shaft；Outside the housing
Power switch is provided with, the power switch respectively electrically connects with motor and motor power.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement.
Further, the housing is made up of anti-rust metal material.
It is using the above-mentioned further beneficial effect of scheme：Ensure the health of syringe, prevent syringe corrosion from causing to note
Hygienic issues when penetrating.
Further, the motor is stepper motor.
It is using the above-mentioned further beneficial effect of scheme：Using the characteristic of stepper motor, an electric current arteries and veins is being received
When rushing, stepper motor can rotate fixed angle, so as to reach accurate quantitative analysis injection.
Further, the motor power is stepper motor driver.
It is using the above-mentioned further beneficial effect of scheme：Multiphase SECO electric current is provided for stepper motor, ensures step
The operation of stepper motor.
The beneficial effects of the utility model are：Facilitate user to carry and operate, arduously injected without user, it is convenient continuous
The operation of interruption calibrated shot, the purpose of calibrated shot is reached by Mechanical course.
Brief description of the drawings
Fig. 1 is a kind of fixed-quantity injector structural representation of the utility model.
In accompanying drawing, the list of parts representated by each label is as follows：
1st, housing, 2, syringe shell, 3, piston, 4, push rod, 5, motor, 6, motor power, 7, dentation, 8, gear,
9th, power switch.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As shown in figure 1, a kind of fixed-quantity injector, including housing 1 and syringe, syringe includes syringe shell 2 and from note
The push rod 4 that the one end of emitter shell 2 is stretched into syringe shell 2, one end that push rod 4 is stretched into syringe shell 2 are provided with piston 3, push rod 4
Piston 2 is promoted to be slided in syringe shell 2, the other end of syringe shell 2 is provided with injection head, and the one end of syringe 2 is placed in housing 1
It is interior；Motor 5 and motor power 6 are provided with housing 1；Dentation 7 is arranged at intervals with push rod 4；Be provided with the axle of motor 5 with
The gear 8 that dentation 7 is engaged；Power switch 9, power switch 9 and motor 5 and motor power 6 are provided with outside housing 1 respectively
Electrical connection.
Preferably, housing 1 is made up of anti-rust metal material, prevents corrosion from being impacted to the health of medicine equipment.
Preferably, motor 5 is stepper motor；Stepper motor is that electric impulse signal is changed into opening for angular displacement or displacement of the lines
Ring controlled motor, its rotation are run step by step with fixed angle, and the rotating speed of motor, the position stopped being solely dependent upon
The frequency and umber of pulse of pulse signal.
Preferably, motor power 6 is stepper motor driver, and stepper motor can not be directly connected in AC or DC power
Work, stepper motor driver is exactly the multiphase time schedule controller for stepper motor time sharing power supply.
Embodiment：User pulls push rod to retreat, and by decoction out of syringe needle inhalation syringe, during injection, presses power switch,
Stepper motor electric impulse signal just is given by stepper motor driver, stepper motor is rotated fixed time with fixed angle
Number, drive push rod to promote fixed distance by the dentation on gear and push rod, reached the purpose of calibrated shot.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
