Accompanying drawing explanation
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in further detail.
Fig. 1 is the structural representation of Novel medical injector.
In figure: syringe 1, syringe needle 2, piston 3, piston rod 4, overhead gage 5, lower baffle plate 6, push-rod electric machine 7, push rod 8, upper rack posts 9, lower fulcrum bar 10, upper expansion link 11, lower expansion link 12, tightening knob 13, motor switch 14, LED 15, bar shaped reinforcement 16, on hold ring 17, under hold ring 18, ring 19 is held on the right side, first switch valve 20, exhaust hose 21, second switch valve 22.
Detailed description of the invention
nullAs shown in Figure 1，A kind of Novel medical injector，Including syringe 1，Left end at syringe 1 connects syringe needle 2，Piston 3 it is provided with in syringe 1，Right-hand member at piston 3 is also associated with piston rod 4，Top right-hand member at syringe 1 is provided with the overhead gage 5 extended straight up，Bottom right-hand member at syringe 1 is provided with the lower baffle plate 6 extended straight down，It is additionally provided with push-rod electric machine 7 in the right of piston rod 4，And the push rod 8 of push-rod electric machine 7 extends the most to the left，The left end of push rod 8 is connected with the right-hand member of piston rod 4 simultaneously，Push-rod electric machine 7 further respectively has the upper rack posts 9 extended straight up and the lower fulcrum bar 10 extended straight down，Expansion link 11 on horizontally disposed it are also associated with between overhead gage 5 and upper rack posts 9，Horizontally disposed lower expansion link 12 it is also associated with between lower baffle plate 6 and lower fulcrum bar 10，And on upper expansion link 11 and lower expansion link 12, further respectively have tightening knob 13；Syringe 1 is additionally provided with motor switch 14, and motor switch 14 is connected with push-rod electric machine 7, top left at syringe 1 further respectively has LED 15 simultaneously, LED switchs and for the lithium battery being powered LED 15, and LED switch is connected in series with LED 15.
Under the above constitution, by being provided with push-rod electric machine 7, the most just can effectively replace manual operation realize to medicinal liquid mild, uniformly inject.Wherein, when using push-rod electric machine 7 to operate, can first regulate expansion link 11 and the length of lower expansion link 12 so that upper rack posts 9 and lower fulcrum bar 10 closest away from overhead gage 5 and lower baffle plate 6 respectively, then screw tightening knob 13.And further, when needs are switched to manual operation by motor operation, just the push rod 8 of push-rod electric machine 7 first can be regulated to the longest, then unscrew tightening knob 13, the most just the manual operation to syringe, this serviceability being greatly improved syringe and the scope of application can have been conveniently realized.
