Abstract

The utility model relates to a good safe one-off filter injector comprising a syringe, a pintle glide connected with the syringe, the front-end of the pintle is fixedly connected with the sealed rubber band and the back-end is disposed with the handle, the front-end wall of the pintle is connected with the movable dust gauze by the rotation of the pin roll. The utility model has the advantages of that as the front-end wall of the pintle is connected with the movable dust gauze by the rotation of the pin roll, when to be extracted the drugs, the movable dust gauze can be opened, can not afford filtering role; when to be injected the drugs, the movable dust gauze can not be opened, can afford filtering role, the impurity of the syringe can be filtered, the safety of the injection and the vein injection can be improved.

Description

The disposable filtering syringe

Technical field

This utility model relates to a kind of armarium, relates in particular to a kind of disposable filtering syringe.

Background technology

At present, the disposable syringe that hospital or community medicine outpatient service are used mainly comprise syringe, with the pintle that syringe is slidingly connected, the pintle front end is fixedly connected with sealing rubber ring, the rear end of pintle has the pintle handle.When using this kind syringe to extract medicine, small impurities such as cullet etc. can be drawn in the syringe, be easy to small impurities is injected in patient's body by intramuscular injection or quiet pushing away then, therefore, use present syringe intramuscular injection or quiet to push away drug safety poor.

Summary of the invention

The disposable filtering syringe that safety was good when the purpose of this utility model provided a kind of the use.

For achieving the above object, the technical scheme that this utility model adopted is:

A kind of disposable filtering syringe, comprising: syringe, with the pintle that syringe is slidingly connected, the pintle front end is fixedly connected with sealing rubber ring, the rear end of pintle has the pintle handle, its characteristics are; On the needle cylinder wall of the front end in the syringe by the bearing pin active filters net that has been rotatably connected.

The utility model has the advantages that: when using this utility model to take out medicine, since on the needle cylinder wall of the front end in the syringe in this utility model by the bearing pin active filters net that has been rotatably connected, the active filters net can be opened when taking out medicine, not filtration, and when injectable drug, the active filters gateway closes, and plays filtering effect, so just the contaminant filter in the syringe can be fallen the safety when having increased syringe intramuscular injection or vein and pushing away medicine.

Description of drawings

Fig. 1 is this utility model structural representation:

Fig. 2 is Figure 1A-A cross-sectional schematic.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment this utility model is further described:

A kind of disposable filtering syringe, as shown in Figure 1, 2, the pintle 4 that is slidingly connected comprising: syringe 3, with syringe 3, pintle 4 front ends are fixedly connected with sealing rubber ring 5, the rear end of pintle 4 has the pintle handle, on the needle cylinder wall of the front end in the syringe 3 by the bearing pin 1 active filters net 2 that has been rotatably connected.

This utility model beneficial effect is: since on the needle cylinder wall of front end in the syringe in this utility model by the bearing pin active filters net that has been rotatably connected, when using this utility model to take out medicine, the active filters net can be opened, not filtration, and when injectable drug, the active filters gateway closes, and plays filtering effect, so just the contaminant filter in the syringe can be fallen the safety when having increased syringe intramuscular injection or vein and pushing away medicine.
