Description

A kind of non-injection syringe

Technical field

The utility model relates to a kind of syringes, more specifically to a kind of non-injection syringe.

Background technique

Syringe is a kind of common medical instruments, is mainly used for pumping liquid or injects immediately after injecting liquid, is infused Emitter can be used for Medical Devices, container, the scientific instrument in such as some chromatographies and inject across diaphragm of rubber, clinical at present On the syringe interface that uses all be it is general, do not distinguish injection and non-injection syringe, therefore, non-injection injection It is easily used as injection syringe after device aspiration medicinal liquid, patient is caused to injure.

Utility model content

The utility model provides a kind of non-injection syringe for externally applied drug suction, can effectively inject with injection Device is distinguished.

To achieve the above object, a kind of non-injection syringe provided by the utility model, including transparent outer housing and Push-pull device at fixed, the outer housing include the stack shell equipped with graduation mark, and described stack shell one end is equipped with nipple, outside the nipple Diameter and length are greater than the outer diameter and length of injection syringe nipple, and the stack shell other end is additionally provided with end cap；Described pushes away Drawing device include can in the outer housing along the piston that move of passage direction, the piston successively with piston shaft, piston Handle is connected.

Further, the piston is red.

Further, the nipple outer diameter is 5~7mm, and length is 23~27mm.

Further, it is connected with the rubber plug for preventing leakage on the outside of the nipple, is equipped with groove in the rubber plug And it is adapted with nipple.

Beneficial effect

Compared with prior art, the utility model has the advantage that

1, the utility model increases nipple outer diameter and length, in this way neither by the size of change syringe nipple The use for influencing non-injection syringe, also prevents it from docking with the syringe needle of injection syringe, to inject with injection Device differentiates, and prevents from damaging patient；

2, the utility model is further distinguished from injection syringe, prevents to infuse by the color of change syringe piston Emitter is obscured using and is damaged to patient；

3, because syringe nipple becomes larger, after drawing liquid, the surface tension of liquid may be not enough to prevent in syringe Liquid outflow, the rubber plug being arranged outside nipple can make hydraulic seal in non-injection syringe, at the same also further with injection It is distinguished with syringe.

Specific embodiment

With reference to the accompanying drawing, specific embodiment of the present utility model is described in detail, it is to be understood that this is practical Novel protection scope is not limited by the specific implementation.

The embodiments of the present invention are such that as shown in Fig. 1~2, a kind of non-injection syringe, including transparent Outer housing 1 and push-pull device at fixed 2, the outer housing 1 include the stack shell 11 equipped with graduation mark 111, and described 11 one end of stack shell is set There is nipple 12,12 outer diameter of nipple and length are greater than the outer diameter and length of injection syringe nipple, the stack shell 11 The other end is additionally provided with end cap 13；The push-pull device at fixed 2 includes the piston that can be moved in the outer housing 1 along passage direction 21, the piston 21 is successively connected with piston shaft 22, piston handle 23.The utility model is by changing syringe nipple 12 Size, that is, increase nipple 12 outer diameter and length, so neither influence non-injection syringe use, also prevent its from note It penetrates and is docked with the syringe needle of syringe, to differentiate with injection syringe, prevent from damaging patient.

In the present embodiment one, the piston 21 is red.The face that the utility model passes through change syringe piston 21 Color is further distinguished from injection syringe, prevents syringe and obscures using and damage to patient.Outside the nipple 12 Diameter is set as 6mm, and length is set as 25mm.

Embodiment two and the difference of embodiment one are: the rubber plug for preventing leakage is connected on the outside of the nipple 12 14, the rubber plug 14 is interior to be equipped with groove and is adapted with nipple 12.Because syringe nipple 12 becomes larger, the utility model is used After drawing liquid, the surface tension of liquid may be not enough to prevent the liquid in syringe from flowing out, the rubber plug being arranged outside nipple 12 14, it is adapted by its internal groove structure with nipple 12, can preferably cover tightly, make hydraulic seal in non-injection syringe It is interior, while also further being distinguished with injection syringe.

Above are merely preferred embodiments of the utility model, it should be pointed out that for those skilled in the art, Under the premise of not departing from the utility model structure, several modifications and improvements can also be made, it is practical new that these all will not influence this The effect and patent practicability that type is implemented.
