Abstract
The utility model provides a quantity-controllable injector. The injector mainly comprises needle tubing and a push rod which slides in the needle tubing. The injector is characterized in that a limiting apparatus is arranged on the push rod. The quantity-controllable injector has the advantages of being capable of guaranteeing that the quantity of a liquid to be injected continuously is accurate, and the injector is simple and convenient to operate.
Description
Technical field
This utility model relates to medical devices.
Background technology
At present the minimum model of disposable syringe is 1 milliliter, though minimum scale can be as accurate as 0.01 milliliter, clinical manipulation continuously during injection, often is difficult to accomplish precisely if desired under the prerequisite of not dialling pin, causes the liquid that will inject too much or very few.
Summary of the invention
The purpose of this utility model is to provide a kind of syringe of can continuous and quantitative injecting.
This utility model provides a kind of controlled amounts syringe, mainly comprises needle tubing and push rod, and push rod slides in needle tubing, it is characterized in that: stop is housed on the push rod.
The controlled amounts syringe that this utility model provides, its stop can be spring clips, limit the push rod displacement with the spring clip of required different in width.
The controlled amounts syringe that this utility model provides, its spring clip can be equipped with slide plate, and the different length that stretches out with slide plate limits the displacement of push rod.
The controlled amounts syringe that this utility model provides can have navigation button on its slide plate, on the intermediate plate of spring clip chute is arranged, the length of stretching out with the Position Control slide plate of navigation button in chute.
The controlled amounts syringe that this utility model provides, its chute can have side channel, so that the navigation button location.
The controlled amounts syringe that this utility model provides, its chute can be step-like, the navigation button location of being more convenient for.
The controlled amounts syringe that this utility model provides can have the transmission bar on its slide plate, on the intermediate plate of spring clip drive can be arranged, and adjusts the length that slide plate stretches out to rotate drive.
The controlled amounts syringe that this utility model provides, its drive and transmission bar pair can be that friction pulley and friction plate pair, gear and tooth bar pair or sprocket wheel and chain auxiliary driving wheel can be friction pulleys, and the transmission bar is friction plate, to obtain more micro-displacement.
The controlled amounts syringe that this utility model provides has scale on its stop, so that direct reading.
The controlled amounts syringe that this utility model provides, its advantage is: can guarantee that the amount of liquid that will inject continuously is very accurate, easy and simple to handle.
