Abstract
The invention discloses a syringe with a filtering net. The syringe structurally comprises a piston cylinder, a piston and the filtering net, wherein the filtering net is arranged in the piston cylinder, and the filtering net is arranged at the front end of the inside of the piston cylinder. The syringe has the beneficial effect that foreign matters are prevented from entering the syringe and human body.
Description
Technical field
The present invention relates to a kind of syringe, relate in particular to a kind of syringe with drainage screen.
Background technology
Traditional syringe does not have drainage screen, and the shortcoming of this syringe is to stop the foreign body in the medicinal liquid to enter syringe, also can't stop the foreign body in the medicinal liquid to enter in the human body.
Summary of the invention
For above problem, technical problem to be solved by this invention is to provide a kind of syringe with drainage screen, and it is practical, and cost is low.
In order to solve above technical problem, technical scheme of the present invention is as follows:
A kind of syringe with drainage screen, its structure comprises piston cylinder, piston and drainage screen, and described drainage screen is located in the described piston cylinder, and described drainage screen is located at the front end in the described piston cylinder.
The invention has the beneficial effects as follows: can prevent that foreign body from entering in syringe and the human body.
Description of drawings
Fig. 1 is that the central shaft of the embodiment of the invention is to cutaway view.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in Figure 1, its structure of the present invention comprises piston cylinder 1, piston 2 and drainage screen 3, and drainage screen 3 is located in the piston cylinder 1, and drainage screen 3 is located at the front end of piston cylinder interior 1.
The present invention stops foreign body to enter in the syringe like this: be drawn in the syringe because medicinal liquid is front end from piston cylinder, be provided with drainage screen because the front end in piston cylinder is pressed close to the place of medicinal liquid entrance, can't enter outward so foreign body just is stopped in syringe.
