Abstract
Description
The present invention relates to a syringe having a stick-restricting function.
2. Description of the Related Art Generally, a disposable syringe used in a clinic or the like has a cylindrical barrel in which an injection liquid discharging portion is formed, a plunger so that the plunger can be moved inward along the longitudinal direction of the barrel, So as to provide a compressive force or a suction force while moving. A needle body having a needle body coupled to the needle at the outer side is detachably coupled to the injection liquid discharge portion and a needle protection cover is detachably coupled to the needle body so as to protect the needle in a completely wrapped state.
However, such a conventional disposable syringe has a risk that foreign substances may flow into the body when the drug solution is inhaled in various ampoules including a glass ampule during its use. Accordingly, in order to prevent such a danger, a filter type syringe having a filter or a filter is proposed.
In the conventional filter type syringe, a separate suction dedicated needle is separately provided in the case of the filter attachment type syringe, and a filter having a filtering function is mounted in the hub of the filter type syringe needle.
However, since the filter type syringe according to the related art has a structure in which a filter latching portion and a filter latching portion are additionally installed and fastened to assemble and fix the filter mounted inside the hub, the suction- And it is inconvenient to reassemble the needles for injection into the body.
In addition, the filter type syringe according to the related art has a disadvantage that it is necessary to maintain the respective disposal caps for the filter needle for inhalation of medicines and the needles for the human body. In the replacement process of the needles, And there was a possibility of contact with the body part.
1A shows a cross-sectional view of a conventional filter type syringe 1. Fig. 1B shows an exploded cross-sectional view of a conventional filter type syringe 1. 1A and 1B, the
However, the filter-type injector 1 according to the prior art also has a problem that the conventional filter-type injector 1 has a risk of sticking to the needle of the user.
Therefore, there is a demand for a syringe capable of preventing sticking while improving the filtration function.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a needle- The present invention provides a filter-type syringe having a stick preventive function capable of preventing a stick injury caused by a sticking of a stick.
It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are not intended to limit the invention to the precise form disclosed. It can be understood.
SUMMARY OF THE INVENTION An object of the present invention is to provide a syringe having a cylindrical body, a barrel head provided at an upper end of the body and protruding upward, a barrel having a mounting groove formed in an upper surface of the body and a flange at a lower end thereof; A needle unit attaching / detaching member which is inserted into the mounting groove and has a fitting hole formed at the center, a fitting protrusion formed at one side of the fitting hole, and an inner space; A needle unit having a needle attaching portion to which the needle is attached, and a fitting portion having a fitting groove to be fitted in the fitting protrusion; And a detachable cap which is inserted into the barrel and has an inner space and which is detachable to seal the upper opening in a pull-in mode and to open the opening in a safe mode and is moved by a user to provide a suction force or a compressive force, And a plunger for drawing the drug solution stored in the barrel into the barrel through the needle.
In addition, a locking protrusion formed on the inner surface of the upper end opening of the plunger, and a locking groove formed on the outer surface of the detachable locking cap and mounted by the locking protrusion.
The plunger may further include a plunger head coupled to an upper end of the plunger and compressing the needle unit detachment member after completion of the injection of the chemical liquid.
