2 Claims, 3 Drawing Figures PATENTEDJUN 1 7 m5 SHEET im ow mm Eu 0% mm TIP ASSEMBLY FOR SYRINGES SUMMARY OF THE INVENTION This invention relates to apparatus in the syringe field and, more particularly, to a tip assembly for use in conjunction with a syringe.

In this age of specialization in the medical field, it is imperative that some action be taken to cut down the high number of component requirements, particularly with regard to syringes and related apparatus. It is with this in mind that the present tip assembly has been developed.

In view of the foregoing, it is an object of this invention to provide a tip assembly for syringes which has great adaptability both with regard to the syringes on which it is used and to the use to which the syringes are put.

It is yet another object of this invention to provide a tip assembly which will provide safer means for storage ofthe syringe with inserted cannula, ready for use upon removal of the cap or cap and body depending upon the use prescribed.

The above and additional objects and advantages will become more apparent when taken in conjunction with the following detailed description and drawings.

IN THE DRAWINGS FIG. I is a plan view partly in section illustrating the tip assembly and its attachment to a syringe,

FIG. 2 is a view showing the use of the tip assembly with a flexible dispensing bag, and

FIG. 3 is a view depicting the use of the tip assembly wherein the cap and main body have been removed and the needle has been introduced into a bottle of medicament.

DETAILED DESCRIPTION As best illustrated in FIG. 1, the tip assembly comprises a cylindrical main body 12 having an open forward end I4 and a partly closed back end 16. The inner surface I8 of the main body 12 is provided with a pair of axially spaced annular sealing rings adjacent the back end I6. An integral cylindrical inner body 22 is coaxially positioned within the main body 12 forwardly of the sealing rings 20. This inner body 22 is attached to the main body I2 by means of a flangelike member 24 extending inwardly from the inner surface 18 of the main body 12. The outer surface 26 of the inner body 22 is equidistant from the inner surface 18 of the main body. The inner surface 28 of the inner body 22 is hexagonal in cross section for cooperation with the needle hub as will be described later.

Referring to FIGS. I and 2, the inner surface 18 of the main body I2 is provided with a retaining groove 34 adjacent the forward end of said body. A cap 36 fits into the open forward end I4 and is provided with locking ring 38 on its outer cylindrical surface for engagement with the retaining ring 34 to hold the cap in position on the main body. In addition, the cap 36 is provided with a plurality of longitudinally extending spacing bars 40 equispaced around the outer surface 42 of the cap 36. The length of the spacing bars 40 is such that the end opposite of the cap head 44 will abut the front extremity 45 of the main body 12.

A needle assembly 48 is carried by the inner body 22 with the hexagonal portion 50 ofthe needle hub 52 fitting into the hexagonal opening 28 in the inner body 22. More specifically, the needle hub 52 comprises an enlarged rear portion 54, a hexagonally shaped midportion 50 and a forward portion 56 having a diameter smaller than that of the mid or rear portion 50 and 54., respectively. The hub 52 is provided with a longitudinal throughbore into which needle 60 is introduced at the forward hub end. The needle is conventionally held in the hub by swaging, however, any other suitable means may be used for the purpose of fastening the needle to the hub in an operational manner. The length of the needle 60 is such that a portion of same extends out wardly beyond the open end 14 of the main body 12. The rear enlarged hub portion 54 is formed with an upstanding outward lip 64 on its open end while the inner surface 66 of the rear hub portion 54 is provided with the conventional Luer taper.

The tip assembly of this invention can be used with a large capacity syringe of the type disclosed in pending application Ser. No. 40l,272. filed Sept. 27, I973. in the names of Elliot Bartner, Edward M. Curley. She]- don Kaplan and Stanley J. Sarnoff.

The tip assembly 10 is received by the syringe barrel 70 in the following manner. The tip assembly mounting arrangement comprises a threaded body portion 72 threadedly carried in an appropriately threaded portion 74 of the syringe barrel 70. A horizontal hexagonally shaped portion 76 extends outwardly from the threaded body portion 72 for wrench use when assemblying the unit. An outer sleeve 78 projects forwardly from the horizontal portion 76 and has its inner surface 80 formed with conventional Luer-Lek threads 82. An inner sleeve extends forwardly from the body 81 coaxially within the outer sleeve 78. The outer surface 92 of the inner surface 90 is provided with the usual Luer taper to cooperate with the Luer taper of inner surface 66 of the needle hub rear portion 54.

In applying the tip assembly 10 of this invention to the syringe unit disclosed in FIG. 1 and more fully covered in copending application Ser. No. 401,272, filed Sept. 27, I973, the tip assembly is slipped onto the syringe body passing the sealing rings 20 of the main body 12 over the outer sleeve 78 and simultaneously causing the hub flange 64 to engage the Luer Lok threads 82 and the tapered outer surface 92 of inner sleeve 90 to snugly engage the inner tapered surface 66 of the rear hub portion 54. Thus the syringe unit complete with re movable tip assembly is ready for use.

One of the conventional uses of a syringe unit such as this is in intravenous apparatus and, more particularly, wherein it is desired to add a medicament to the receptacle from which the liquid is being dispensed. One form of such receptacle is a flexible bag having a plurality of nipple connections extending therefrom which are adapted to accommodate con entional connecting devices.

As illustrated in FIG. 2, the cap 36 has been removed from the tip assembly I0 and the needle 60 has been introduced into and through flexible stopper carried on the bag nipple 102.

As illustrated in FIG. 3, the cap 36 and main body 12 with integral inner body 22 have been removed from the tip assembly 10 so that the long shank of the needle 60 is available for insertion in various types of medicament containing units 110. As shown, the needle 60 is passed through a flexible stopper 112 to reach the medicament 114.

As might be expected, the body of the tip assembly can most advantageously be made from a plastic material. The cannula and hub should be made from con ventional materials which are well known to the art. Adaptability and versatility of cannula size with regard to different types of syringes make the tip assembly aforedescribed a very useful and necessary piece of apparatus.
