. mwe 00,, 0E PHILADELPHIA, v ENNsYLv NIA, A CORPORATION 0E PENNSYLVANIA t V g DAET E NEEDLE My inventionrelates to a new and useful a as Well as for use on collapsible tubes. a

My invention more particularly relates to a novel needle adapter for syringes and collapsible tubes of the character, whereby'neeldles, of different sizes may. be ,employed interchangeably andw-hereby a'broken, damaged, clogged or contaminated needle can be removed and replaced by a new one instan taneously' so that notime is lost in cases of emergency. 7

One object of my invention is to provide'a novel adapter which may be operativelycoln nected with or inserted into the interior of a l syringe or collapsible tube near-the ejection I end thereof, instantaneously and-in aliquid tight manner, and to which, in turn, any size mn'eedlemay be coupled or, secured also instantaneously and without any elaborate'fastenling or securing devices. I

A further objectof my invention is to facilitate the introduction of theinjection fluid 'from the syringe or collapsible tube through the hollow needle to the point of application andto eliminate the liability ofthe needle bewardly or inwardly extendingstemfm piercing thejrubber'or other closure on the ejeczle'of collapsible tube, said adapterbeing frictionally or -threadedly retained in position, and a peridantexterision adapted tofit 7 into a correspondingseat in the upper end of a needle, there being' a passage extending through said adapter and forming a ,commu nication from the interiorof the syringe,'to said hollow needle, the passage in said adapt er being much larger thanthe passage in said needle.

'For the purpose of illustrating invention, I have shown in the accompanying drawings,-forms-thereof which are at 'pres' I ent preferred by me since they will give in practice, satisfactoryand reliable'results, al

described.

Inithe accompanying drawings, inwhich -like.'reference characters indicate like parts,

Fig. '1 represents alongitudinal sectional though'itis to .be understood that the'various 'instrumentalities of which my invention consi'sts can be variously arranged and organized and that my invention is not limited to the precisejarrangement] and organization" of these 'instrumentalities as herein shown and vi'ewof an adapter needle and its adjuncts and a hypodermic syringe to which the same is'applicable, certain parts being shown in I elevation.

Fig. 2'represents on an enlarged scale an adapter needle and its adjuncts in detached position.

Fig. 3 represents a longitudinal section view of another embodiment. ofmy inventhejoutlet end of the barrel or cylinder lot the hypodermicsyringewith a narrowedor a tightly engaged by the rubber cap 5 having a I rearwardly extending fiange6, which encloses the bead 4and tightly and snugly engages the tion, Fig. 4 represents a detail View and Figs '75) 5 and 6 represent a modifiedconstruction. l. y

In carrying out my invention I construct" wall 3. H The adapter needle 7 is composed of conical, pendant extension 11' and the oppositely extending needle portion 12,there' bethe members 8 and 9, the member 8 compris-' 1 ting the head or-body portion 10, having a ing apassage 13 through said needle portion, 7 body and conical extension 11 The member 9 is provided with an upper he'adlfZ", having a conicalseat 13 therein, whose contour conforms with the ,outer contour of the conical pendantportion 11, so that the latter is frictionallyand tightly held within the seat 13 when the members" are assembled. ll'desjig' nate's the needle, which is integral with the head 12 and providedwith a passage 15 -there-1 1,00 i I alreadydescribed, but differs from. the construction seen in Figs. 1 and 2 .by the addition of the annular upwardly extending flange 17 which is adapted tightly and frictionallyto engage the rubber cap 5 already described as will be understood from Fig. 3; The bypodermic syringe contains the serum or solution 21 and is provided with a piston or plunger 1801" the usual construction, which is actuated by the piston rod 19 which passes through the closure 20, these parts being of the usual construction. The needle and adapter members 9 and 8 are made of steel or the like and the cap 5 of rubber or similar material.

By the provision of a substantial and rigid adapter member having the upper pointed stem 12, the'piercing of the rubber cap or closure 5 at the ejection end of the syringe is easily and quickly effected and the risk of breakage of the needle is eliminated. The

relatively large passage 13 in the stem 12 facilitates the passage or flow of thefiuid 12 from the cylinder into the relatively restricted passage 15 in the needle 14, and this is especially true when a rather dense or viscous fluid, such as serum or vaccine is being inj ected, since capillary attraction as well as mechanical friction would otherwise tend to retard the free flow of the fluid to its destination. Especial attention is called to the employment of the relatively large passage 13 in the member 8, since by this construction an elon ated'relatively large auxiliary reservoir for the fluid or serum is provided, which in practice enables my novel adapter needle to be readily and instantaneously operative under all conditions of use, which is not always the case when the passages 13 and 15 are of the same restricted area in cross section. It is desirable in emergency cases, where sometimes a patients life is dependent upon the needle functionin instantaneously and positively under all conditions that the needle be instantly operative orcapable of instantly performing its desired function,-and I have found from practical use of my device that it is essential to have the elongated passage orauxiliary reservoir 13 relatively large as compared to the restricted passage 15 particularly when a. rather dense or viscous fluid, as

above explained, is to be handled or injected.

My novel constructionof the adapter member 8 serves to permit of the employment of any size needle, since the extension 11 thereof as well as the coacting seat 13 can be made of needle, all ofwhich can be done in a very little time and with a minimum effort.

It is also. easyfor the operator to use any.

special. standardLuertype slip or screw thread needle, if he desires to use a special size or shape needle for intravenous, intramuscular, subcutaneous and intracutaneous injections. V

It is within the scope of my invention to provide an adapter needle particularly suited for use on collapsible tubes and the like, comprising a body portion having a stem projecting therefrom, an internally threaded "annular flange surrounding said stem and adapted to engage the threaded outlet of a conventional collapsible tube, and a pendant threaded extension adapted to engage a-correspondingly threaded cup shaped seat on one end of'a needle, said stem, extension, and needle having aligning passages upwardly extending, annular, internally.

threaded flange 28 and the pendant externally threaded extension 27 which is engaged by the internally threaded cup-shaped ,head 29 on-one end of a needle 14, the passage 30 in said adapter 25 being in alignment with and Y much larger than the passage 15 in said needle. 31 designates an upwardly projecting stem adapted to project into or enter the nozzle 24 of the tube 22, while 32 designates a gasket ofrubber or other material disposed around the base ofsaid stem 31 to prevent any leakage of the contents of said tube, said gasket being compressed between the nozzle 24 and-the seat in the adapter 25, when the parts are assembled as seen in Fig. 5.

It will also be apparent that I have devised a novel and useful adapter needle construction which is inexpensive to produce and easy to assemblesince the same comprises but two parts and is adapted for a variety of uses. a

It will now be apparent that I have devised a novel and useful construction of adapter needle which embodies the features of advant ge enumerated as desirable in the statement of the invention and the above description and while I have in the present instance shown and described the preferred embodiment thereof which beeni found in practice to give satisfactory'and reliable result s, ,it is to beunderstood that the same is susceptibleof modification in various particulars without departing-from the spirit or scope of the invention or sacrificing any f its advantages.
