A kind of syringe
Technical field
This utility model relates to a kind of syringe.
Background technology
In the process of clinical use syringe and processing syringe; because used pin medicated cap is thinner; consider from security standpoint; the pin medicated cap is forbidden back cover; and the clamping of pin medicated cap and syringe is insecure, and the pin medicated cap comes off easily, and needle point is easily stabbed medical personnel; discarded syringe needle after particularly using does not have safety precautions, cause most probably stab, safety problem such as superinfection.
Summary of the invention
This utility model is that the clamping of the pin medicated cap that run in the use of the present syringe of solution and the processing procedure and syringe is insecure; the pin medicated cap can not return cover; discarded needle point does not have safety precautions; may produce personnel and to stab etc.; cause safety problems such as superinfection, proposed a kind of disposable syringe safe in utilization.
Syringe of the present utility model comprises syringe, syringe needle and pin medicated cap, wherein, syringe needle is connected pintle with syringe close needle section is divided into conical structure, and the bottom edge of this conical structure is the stand bar structure of projection, forms depression between near the part of syringe and stand bar structure connecting pintle; The tail diameter of described pin medicated cap is slightly larger than the syringe diameter, and is provided with at least one wedge shape card base in the afterbody of pin medicated cap.
Pin medicated cap of the present utility model wraps up the entire portion of discarded syringe needle fully; firm with the syringe clamping; pin medicated cap difficult drop-off; simple in structure; in the practical application of disposable syringe, both protected the staff, prevent to be caused infection by needle sting; simultaneously used discarded syringe needle has obtained safeguard protection, has prevented harm such as stabbing in transportation and the processing procedure, superinfection.

The specific embodiment
As shown in Figure 1, 2, syringe of the present utility model, syringe needle 1 is divided into conical structure with the close needle section that is connected pintle 3 of syringe 4, and the bottom edge of this conical structure is the stand bar structure 2 of projection, forms between the part of close the syringe that connects pintle 3 and stand bar structure 2 and caves in; The tail diameter of described pin medicated cap is slightly larger than syringe 4 diameters, and is provided with 2 symmetric wedge shape card bases 6 in the afterbody of pin medicated cap 5.
As shown in Figure 1, this utility model before use, pin medicated cap 5 is enclosed within on the syringe 4 safely, but does not combine with syringe needle, can take off; And after use, as shown in Figure 2, can be with 5 times covers of pin medicated cap, and firmly push away to the syringe direction, the wedge shape card base 6 to the pin medicated cap passes through pintle portion stand bar structure 2, because the resilience force of wedge shape card base 6 and the resistance of syringe, when once more helmet being taken off, the pin medicated cap promptly is stuck in the recess of pintle portion, and complete syringe needle is wrapped up by helmet, has prevented that syringe needle from producing injury to personnel.
