Abstract
The utility model relates to an injection pushing device used for intravenous injection. The utility model has the structural characteristics that an injector is fixedly arranged above a box and a miniature motor is arranged under the box. The wheel gears on the motor shaft of the miniature motor are engaged with a drive gear which drives a gear rack. The tail end of the gear rack is provided with a push plate which is contacted with the pushing handle of the injector. When the motor starts, the pushing handle of the injector can be pushed and then medical liquor can be injected into a vein with a uniform speed. The utility model overcomes the defect caused by inhomogeneous pushing force of intravenous injection in the prior art. The utility model has the advantages of simple structure and convenient operation. The speed of the miniature motor can also be regulated so as to meet the requirements of different injection speeds.
Description
The injecting propeller that this utility model provides a kind of injection for intravenous to use belongs to the medical apparatus and instruments production technical field.
Artificial hand push mode is adopted in intravenous injection at present mostly.This kind mode is easier, but shortcoming is often firmly inhomogeneous in the hand push process, causes the medicinal liquid inlet inhomogeneous.Another kind of intravenous injection mode is to adopt rubber tube, during use rubber tube is bundled into annular, and one stretches tight in the end of syringe, other end the pushing away above the handle at syringe of stretching tight.The defective of this method is bigger, and the power that stretches tight of rubber tube is more ruthless during beginning, and the amount that enters medicinal liquid is big, the blood vessel wall of sharply making a spurt, and the injured blood vessel inwall, patient feels pain; And at back segment, then the rubber tube power of stretching tight reduces, and thrust is also little, and medicinal liquid injects slowly.In the whole injection process, injection thrust differs greatly.
The purpose of this utility model provides a kind of intravenous injection propeller of the transfusion that can remain a constant speed, and this propeller can also provide multiple speed, to adapt to some medicinal liquid, as the slowly requirement of injection of calcium gluconate, penicillin.
The purpose of this utility model is realized like this: the intravenous injection propeller, be equipped with syringe and rack and pinion drive mechanism in the middle of being characterised in that same box; The lower end of gear 1 is meshed with travelling gear 3 on micromachine 2 arbors, and the upper end of gear 1 is meshed with tooth bar 4, a terminal fixedly connected push pedal 5 of tooth bar 4, and the center of push pedal 5 is over against the central axis of the syringe 6 of horizontal positioned.Micromachine 2 can speed governing.
The utility model is described in further detail below in conjunction with accompanying drawing and using method.
Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is the A-A generalized section of Fig. 1.
The syringe that to inhale liquid medicine during use is fixed on the top of propeller box body 7, more angle of rake push pedal 5 is adjusted to syringe push away handle 8 contacted positions, open micromachine 2, liquid medicine just can inject patient's vein equably.Micromachine 2 can speed governing just can satisfy the requirement of different injection speeds.
The small and exquisite practicality of this utility model is made simple, easy to operate.
Claims (2)
1, a kind of intravenous injection propeller is characterized in that in the middle of the same box syringe and rack and pinion drive mechanism being housed; The lower end of gear (1) is meshed with travelling gear (3) on micromachine (2) arbor, the upper end of gear (1) is meshed with tooth bar (4), a terminal fixedly connected push pedal (5) of tooth bar (4), the center of push pedal (5) is over against the central axis of the syringe (6) of horizontal positioned.
