Description

Clinical simple auxiliary intravenous injection booster

Technical Field

The utility model relates to a boost motor, in particular to clinical simple auxiliary intravenous injection boost motor.

Background

Syringes are a common medical device. As early as the 15 th century, kathler, italian, proposed the principle of the syringe. Gas or liquid is primarily drawn or injected with a needle. Syringes may also be used for injection through rubber septa in medical devices, containers, scientific instruments such as in some chromatography.

The existing injector generally carries out injection by pushing a piston rod by hand, but the existing injector is difficult to control generally and cannot keep uniform motion, so that a booster is required for auxiliary control.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a clinical simple and easy supplementary intravenous route boost motor to the current syringe that provides generally injects through the hand push piston rod among the solution above-mentioned background art, but general control is comparatively difficult, can not keep the uniform velocity motion, so needs the boost motor to carry out supplementary problem.

In order to achieve the above object, the utility model provides a following technical scheme: a clinical simple auxiliary intravenous injection booster comprises a first clamping hand, wherein the middle part of the first clamping hand is movably connected with the middle part of a second clamping hand through a rotating shaft, a mechanical timer is fixedly arranged at the clamping part of the first clamping hand, a gear is fixedly arranged at one side of the inner wall of the mechanical timer, a main push rod is meshed and connected with one side of the gear, the main push rod is in threaded connection with the mechanical timer, a fixed block is fixedly arranged at one end of the main push rod, a bearing is fixedly arranged inside the fixed block, the inner ring of the bearing is fixedly connected with the end of the fixed rod, a mounting groove is formed in one side of the fixed block, a fixed rod is fixedly arranged on one side of the mounting groove through a spring, clamping parts of the first clamping hand and clamping parts of the second clamping hand are fixedly provided with clamping plates, and an injector body is arranged between the clamping plates, the inside movable mounting of syringe body has the piston rod.

As an optimized technical scheme of the utility model, the inner wall fixed mounting of splint has the rubber pad.

As an optimized technical solution of the present invention, one end of the piston rod is connected with the fixing rod.

As an optimized technical scheme of the utility model, the trompil has been seted up to one side on second tong top.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model relates to a clinical simple and easy supplementary intravenous route boost motor, the gear working method and the steel tape measure through mechanical timer return the working method that contracts, through the timing of timer, make the afterbody of retrieving the syringe section of thick bamboo at the uniform velocity to the main push rod of syringe piston handle extending direction, make the liquid in the syringe section of thick bamboo at the uniform velocity of pushing in the fixed time finish.
