Adaptor for hypodermic syringe
US 3822701 A
Abstract
An adaptor for a hypodermic syringe with a central outlet comprising a hypodermic needle having an inlet section at one end, an outlet section at the other end laterally offset from the inlet section and terminating in an insertion point and an intermediate section transverse to and connecting the inlet and outlet sections and a plastic body embedding the inlet, intermediate, and outlet sections with the insertion point exposed at one end of the body and with an integral fitting at the other end of the body surrounding the inlet end of the needle for mounting the needle on said discharge outlet and for connecting said discharge outlet to the needle.

1 ADAPTOR FOR HYPODERMIC SYRINGE This invention is a hypodermic needle adaptor constructed to keep the needle point parallel to the vein during intravenous injection. The hypodermic needle has an inlet section, an outlet section laterally offset from the inlet section and terminating in an injection point, and an intermediate section transverse to and connecting the inlet and outlet sections, all of which except the injection point are embedded in a plastic body having an integral fitting at the inlet end of the needle for mounting the adaptor on and connecting it to the discharge of the hypodermic syringe.

In the drawing, the single FIGURE is a fragmentary section through a hypodermic syringe with a preferred form of adaptor mounted thereon.

The syringe has a hub l with a Luer fitting 2 and a discharge duct 3 extending through the fitting. The hub is centrally located on the axis of the body 4. .The particular syringe illustrated is described in greater detail in application Ser. No. 98,226, incorporated by reference. Other syringes may be substituted for the syringe shown. Such syringes have been equipped with axially extending straight hypodermic needles.

The adaptor has a one piece bent metal hypodermic needle of substantially uniform cross section with a generally horizontal inlet section 5, an outlet section 6 laterally offset from and parallel to the inlet section. The connection between the inlet and outlet sections is made through the transverse section 7 substantially at right angles to the inlet and outlet sections and connected to the inlet and outlet sections by bends 8 and 9. The outlet section 6 terminates in an injection point 10 which lies substantially in the plane of the lower side of the body 4 of the syringe so that the point can be easily inserted substantially parallel to the vein and avoid penetration of the side walls of the vain. While the needle so far described is desirable from the point of view of injection, it lacks rigidity and is difiicult to mount on the hypodermic syringe.

To overcome both of these problems, a thermoplastic body 11 is injection molded around the inlet section 5, the intermediate section 7, the bends 8 and 9 and a substantial portion of outlet section 6. One end of the body terminates in the hub 12 surrounding the outlet section 6 and receiving a needle protector 13. The other end of the body terminates in a Luer fitting l4 surrounding the inlet end 15 of the needle and complementary to the fitting 2 on the syringe.

The adaptor is adapted to injection molded plastics. Because the intermediate section 7 is at right angles to the inlet and outlet sections 5 and 6, molding is simplified. The bends 8, 9 positively anchor the needle in the body 11. The rigidity imparted to the needle by the body eliminates deflection which could interfere with the accuracy of insertion of the needle.

What is claimed is:

1. In combination, a hypodermic syringe means having an axially extending body with an integral centrally located hub at one end providing a discharge fitting with an axially extending discharge duct extending through the fitting, said syringe being capable of hypodermic injection when a straight axially extending hypodermic needle is mounted on said discharge fitting, a hypodermic needle of substantially uniform cross section and bent to provide an inlet section at one end coaxial with said discharge fitting, an outlet section at the other end laterally offset from and generally parallel to the inlet section and terminating in an insertion point for insertion into a vein substantially parallel to the vein to avoid penetration of the side walls of the vein, an intermediate section transverse to the inlet and outlet sections, a bend connecting the inlet section to the intermediate section, and another bend connecting the intermediate section to the outlet section, and structure for increasing the rigidity of said needle when mounted on said discharge fitting, said structure comprising an injection molded thermoplastic body molded about and embedding the inlet, intennediate and outlet sections and the bends of said needle with the insertion point exposed atone end of the body, said body having a fitting complementary to said discharge fitting integral with the other end of the body and surrounding the inlet end of the needle rigidly mounting the needle on said discharge fitting and connecting said discharge duct to the inlet end of the needle, said body anchoring and imparting rigidity to the needle and eliminating deflection which could interfere with the accuracy of insertion of the needle.

2. The combination of claim 1 in which the discharge fitting on the hub of the syringe is a Luer fitting.

3. The combination of claim I in which said body has a hub at said one end for receiving a cover for said exposed point.

4. The combination of claim 1 in which said intermediate section of the needle is at right angles to said inlet and outlet sections.
