The present invention relates to syringes of the hypodermic type and embodies, more particularly, an improved` hypodermic syr inge capablel of use with-needles and other l 5 tools having varyingsizeldbases In ;)ractice,"it`f is desirablein hypodermio work to `useneedlesand other attachments l of varying sizes for a given sizeof `syringe and` in existingeconstructions, no simple and 10 effective devices are available forinterchang` i @o ing sizes, the tools being selectively 4applied tothe syringe with equal facility. l A
l further object of thevi "vention isto af-l ford a means for locking the tool tothe sy`r` inge in such manner that a predetermined relationship bet-ween portionsof thetool `and the syringe'may be maintained when securing the toolto the barrel of the syringe.
f The "attainment of the above objects is" ac` complished by "the provision of an adapter 30 upon the barrel of the syringelwhich has a fitting to receive the baseiof theneedles or other tools, the fitting being of such character that the needles and tools arev fitted-with equaldegrees of nicetygregardless of their sizes. Cooperating with this fitting isa man ually operable retaining member which holds the needle'orftoolin operative relation to ,thettingl `ing means whenwthe Further objects of the inventiomnot spe? cifically enumerated above,w1ll appear as the ingthe specific manner in which the needle is secured to the barrel of the syringe.
F1gure 3 1s a view similar to Figure 2,
showing the syringe carrying a catheter or l curved nozzle,` l l Y N Flgurelt 1s a perspective view showing the manually operable means for `securing the needle orrtool to theladapter. n F1gure 5 1s a perspective view showing the adapterwhich is carried by the syringe bar-` i e rel, and uponlwlnch the needles or tools are secured.` Incidentally, this view, taken with which it assumes with respect to the `retainlatter is applied thereto during assembly. i i Y l 1 n i Figure 6 is a view in side'zelevation of the adapter in loose position ready toreceive a needle. 1 i
` At the outset, it will invention primarilyembodies a connection for securing one` element to another, although. it has been illustrated as a means for securing a needle or other tool to the barrel-of a syr inge. i l ith a view tosettingforth theinvention specifically, reference will now be had'par` beunderstood that `the "Figure 4, shows the adapter `inthe position Y ticularly to Figures 1, 2, t and 5 whereinrl() designates the barrel of a syringe having'` aplunger 11 and a scale 12 for indicating a Adesired volumeof fluid to be injected. At the i end of the barrel .opposite from the'plunger,1a barrel tip 13 may be formed, having an aperL ture 14 through which fluid `may flow. Y
An adapter orcoupling 15 having a recess 16 is ittedfuponithe barrel, thetip of 9 the latter beinglsnugly receivedin the recessl.
An axial passage 1751s formed in the adapter;
preferably in alignment with theaperture 14 female member 23,1vithin which the nozzle ,i or male member 18 is received.` An annular Y (iii bead 2li is formed on the needle base and cooperates with a retaining means to be described hereinafter, to secure the needle to the adapter.
Cooperating with the adapter to hold the needle, is a thimble or bushing 25, threaded internally at 26 to engage the threads 19, and. knurled on its external periphery, as at 27, to facilitate manual operation.` Coaxial with the bushing is a semi-cyclindrical extension 2S having an inwardly extending gripping flange 29. The extension and flange overlie the nozzle 18 as clearly shown in Figure 2. A coaxial apron 30 serves as a keeper and is pressed or otherwise secured to the bushing. An inwardly extending rim 3l on the apron engages the threaded portion of the adapter to prevent the bushing from being` entirely removed when unscrewed from thevadapter.
In Figure 3 the needle is replaced by catheter or curved nozzle 32 having an end fitting 33 similar to the base of the needle 20. Obviously, the manner of securing this fitting to the nozzle is similar to that in which the needle base is Secured to the nozzle in the construction shown in Figures l and 2.
From the foregoing description it will be apparent that the adapter is snuglyv held on the barrel tip and carries the thimble or Vbush ing with the gripping flange'QQ. To apply a needle or other tool to the nozzle, the thimble 25 is advanced toward the end of the nozzle. lhen there is suiicient clearance between the gripping flange and the tapering` -side of the nozzle to receive the bead 24 of the needle base or fitting 33, the needle or tool is slipped over the nozzle and the thimble backed up until the gripping flange 29 thereon engages the bead 24 and securely fits the needle or tool upon the nozzlev The reverse operation is effected when the needle or tool is to be removed. i
`In applying the needle to the syringe, it willbe Vapparent that it is but a simple matter to hold the needle in any position desired, since it need only partake of axial movement during such operation. In this manner the needle is easily held so that its opening will be facing in the same direction as the scale on the barrel of the syringe, thus enabling the instrument to be used more effectively.
From the description as outlined above, it will be apparent that the invent-ion is not restricted to the specific construction'embodied herein, but may be utilized with couplings of many formsand it is not to be limited save as defined in the appended claims.
