ABSTRACT:
1. A hypodermic needle support structure comprising in combination [;] : a plastic main support member having an inner end, and an outer end portion terminating in an outer end; a passage extending longitudinally [therethrough which provides] through said support member to provide access to the interior of said support member from either end thereof; said longitudinally extending passage including a smaller diameter portion adjacent said outer end and a larger diameter portion adjacent to said smaller diameter portion; means defining a shoulder between said smaller diameter portion and said larger diameter portion; [with said support member having at the outer end] ; said outer end portion of said support member including a rigid support section[,]; a generally tubular metal eyelet member ; a hypodermic needle cannula; said eyelet member being disposed in fluid-sealing engagement with said support section and forming a fixed fluid-sealing engagement with [a] said hypodermic needle cannula, said eyelet member having [at the inner end thereof a] an inner end disposed within said smaller diameter portion of said support member and an outer end extending axially through said outer end of said support member; a radially outwardly extending skirt section on said inner end of said eyelet member; said skirt section having an outer diameter which is larger than the diameter of said smaller diameter portion of said longitudinally extending passage in said support member and which is in fluid-sealing engagement with said shoulder between said smaller and larger diameter portions of said longitudinally extending passage; said skirt section [with] having a diameter larger than the outer diameter of said hypodermic needle cannula and [with] said skirt section forming said fluid-sealing engagement with said support section, and said eyelet member having extending axially from the outer end of said skirt section a tubular stem section which extends longitudinally beyond the end of said support section, and said stem section forming said fixed fluid-sealing engagement with said hypodermic needle cannula at a point spaced axially beyond said outer end of said support section the diameter of said stem section of said eyelet member being smaller, throughout its entire length, than the smallest diameter portion of said longitudinally extending passage, whereby said eyelet member may be inserted through said inner end of said support member and said stem section may pass through said outer end of said support member until said skirt section engages said shoulder between said smaller and larger portions of said longitudinally extending passage in said support member.
