Abstract
An injection site apparatus is adapted to be attached to a continuous unbroken portion of a flexible tube of an intravenous delivery set. The apparatus is provided with a recessed channel for supporting and bending a portion of the flexible tube. The apparatus is provided with a piercable closure and a needle guide which are axially aligned with a portion of the recessed channel. The piercable closure and needle guide align a hypodermic needle in axial alignment with the center of said flexible tube to prevent interference therewith.
Claims28
An injection site apparatus of the type adapted to be connected to a flexible tube of an intravenous delivery set, comprising:
- a tube housing,
- a recessed channel in said tube housing for receiving and retaining a continuous unbroken portion of said flexible tube,
- said recessed channel having a straight outlet portion and an adjoining inlet portion formed at an angle thereto for retaining said flexible tube at said angle in said recessed channel,
- a piercable hypodermic needle closure receiver on said tube housing,
- a primary needle guide connecting said piercable closure receiver with a portion of said recessed channel,
- a piercable closure mounted on said piercable closure receiver adapted to be punctured by a hypodermic needle, and
- a secondary needle guide provided on said piercable closure receiver adjacent said piercable closure,
- said hypodermic needle being insertable through said piercable closure and said needle guides to be guided into the center of said flexible tube.
An injection site apparatus of the type adapted to be connected to the intermediate ends of a flexible tube of an I.V. delivery set, comprising:
- a tube housing,
- a hollow channel in said tube housing adapted to receive said intermediate ends of said flexible tube,
- said hollow channel having a cylindrical outlet portion and a connecting cylindrical inlet portion formed at an angle thereto,
- a piercable hypodermic needle closure receiver on said tube housing axially aligned with said outlet portion of said hollow channel,
- a primary needle guide formed in said tube housing between said piercable hypodermic needle closure receiver and said outlet portion of said hollow channel,
- said primary needle guide having a converging shape terminating at its small end in an outlet which is smaller than the inside diameter of said flexible tube,
- a piercable closure mounted in said piercable hypodermic needle closure receiver, and
- a secondary needle guide having an inlet axially aligned with said primary needle guide,
- said secondary needle guide forming means for aligning a hypodermic needle with the inside diameter of said flexible tube.
An injection site of the type adapted to guide a hypodermic needle into the interior of a flexible tube of an I.V. delivery set, comprising:
- a tube housing,
- a hollow channel in said tube housing adapted to receive the intermediate ends of said flexible tube,
- said hollow channel having a cylindrical outlet portion and a connecting cylindrical inlet portion formed at an angle thereto,
- a primary needle guide formed in said tube housing in axial alignment with said cylindrical outlet portion,
- said primary needle guide comprising a narrow tapered conical shape terminating at its small end in an outlet connected to said cylindrical outlet portion,
- a piercable closure mounted in said tube housing adjacent the large end of said primary needle guide, and
- a secondary needle guide mounted in said tube housing in axial alignment with said piercable closure, said primary needle guide and said cylindrical outlet portion of said hollow channel, whereby a hypodermic needle inserted through said needle guides and said piercable closure is guided into the center of said hollow channel.
