Abstract

The present invention relates to a needle safety device for an intravenous catheterization device which includes a base capable of receiving the needle between opposite jaws which are connected to the base and can be acted upon by the needle. The jaws move between the extended position in which they interact with the obstruction in the two-wing housing of the intravenous catheter device. The jaws allow relative movement of the needle with the base when extended, lock around the tip of the needle once it has passed through the jaws, and prevent relative movement of the needle with the base when the jaws are folded. The needle for the intravenous catheter can then be placed securely with the tip of the needle inside the needle safety device.

General Description of the Invention The main objective of the present invention is to provide a means of safety for a Led needle which overcomes the disadvantages of the prior art. Another objective of the present invention is to provide an intravenous catheterization device in which a non-tapered wing housing cylinder is used which reduces the overall volume of the intravenous catheter. The AT objective of the present invention is to provide a needle safety device which has a streamlined profile and thus is less Rass when produced and used. Accordingly, the previous objectives are clarified; and objectives (RY) in addition to the advantages of the present invention; in the next disclosure. 0 The previous objectives are achieved by means of the material mentioned in the attached protection elements. The safety device for the needle of the invention includes a base capable of receiving the needle between the two opposite jaws connected to the base that has the ability to be affected by the needle. Together, the two jaws form a reversible assembly mechanism. It increases when the needle is between the jaws and the fold position when the needle is not between the jaws. The ae safety allows the needle to move relative to the base when the jaws are extended. The jaws close around the tip of the needle once the needle slides through the space between the jaws; The jaws prevent the relative movement of the needle with the base when the jaws are folded. mo

A needle safety device may be used with an intravenous catheter device containing a flexible catheter

Mounted on the wing housing. The intravenous catheter has an internal obstruction within the housing

pterygoid. The jaws on the safety device of the needle, as previously mentioned, are movable between

The extended position where the jaws are moved outwards by the needle and are prevented from moving past the internal constraint in the folded position when the jaws are closed around the tip of the needle allowing for a safety device

Allow the needle to move past the internal obstruction while wrapping the needle tip.

According to another touch of the present invention; The needle safety device shall have an inclined portion configured to allow

By moving the safety device of the needle past the obstruction inside the intravenous catheter device when placing

The expansion of the assembly. The obstruction is usually an ile on a ring inside the wing housing.

0 According to another feature of the present invention the jaws have a side perpendicular to the cylindrical side of the wing housing which prevents movement past the obstruction of the intravenous catheter device when the needle safety device is in the extended position. According to another feature of the present invention; The jaws are connected to each other by at least one bond at a distance from the base. At least one bond prevents the jaws from separating too far from each other;
