US 5,405,330 A · Syringe needle holder

Abstract

A pivotal syringe needle holder for use with an injector includes a hub and a ball. A needle is supported by the ball which, in turn, is movably supported by the hub so as to permit the needle to be angularly displaced relative to the hub. The hub is engageable with the injector. The ball and hub are configured to form a ball and socket arrangement which cooperatively permits medicant to be communicated therethrough. A contact seal is formed between the ball and hub to prevent loss of medicant therefrom. A physical seal which may be provided supplemental to, or in place of, the contact seal. A needle may be formed as an integral element of a disposable syringe needle holder or a non-disposable syringe needle holder may support a disposable needle. The ball may be manipulated to displace the needle in a desired position relative to the hub and then may be substantially fixed in this desired position. A latch may be provided to releasably fix the ball relative to the hub which, in turn, releasably fixes the needle relative to the hub.

Dependent claims

A syringe needle holder for use in supporting a syringe needle, comprising:

a hub;
a ball movably supported by said hub, said ball including at least means for supporting a needle;
wherein said ball is further structured and configured to have a concavity therein through which the needle passes and in which the needle is enabled to be radially deflected;
said needle supporting means further including a bore passing through said ball, said bore being dimensioned and configured to tightly receive the needle so as to substantially prevent axial displacement of the needle relative to the ball;
and
means for providing a passageway for fluid communication through said hub, said ball, and said needle.

A syringe needle holder for use in supporting a syringe needle having a bore passing therethrough and for use in combination with an injector configured to carry a carpule having medicament therein, said syringe needle holder comprising:

a ball and socket arrangement including at least:
a hub having a concave surface therein;
and
a ball being supported by said hub and being matingly engageable with a concave surface within said hub, said ball including at least:
means for supporting a needle including a first bore passing through said ball, said first bore being dimensioned and configured to tightly receive the needle so as to substantially prevent axial displacement of the needle relative to the ball;
means for attaching said ball and socket arrangement to the injector;
and
means for providing a passageway for fluid communication from the carpule in the injector through said ball and socket arrangement, and further through the needle.

A syringe needle holder for use in supporting a syringe needle and in combination with an injector configured to carry a carpule having medicament therein, said syringe needle holder comprising:

a ball and socket arrangement including at least:
a hub having a concave surface therein;
and
a ball being matingly engageable with said concave surface of said ball, said ball further being captively and movably supported by said hub, said ball including at least means for supporting a needle;
means for providing a seal between said hub and said ball;
means for attaching said ball and socket arrangement to the injector;
and
means for providing a passageway for fluid communication from the carpule in the injector through said ball and socket arrangement, and further through the syringe needle, wherein said fluid communication means includes
a piercing tip being extendable from said hub into the carpule in the injector, said piercing tip having a first bore passing therethrough from said carpule to said hub;
means defining a second bore passing through said hub, said second bore being in continuous fluid communication with said first bore;
and
means defining a third bore passing through said ball, said third bore simultaneously and continuously being in fluid communication with said second bore and said bore passing through said piercing tip.
