ABSTRACT:
A needle device which is designed for use with subcutaneous access catheter assemblies of the type having an interior chamber in which a needle provides fluid access thereto. The needle device of the invention comprises a needle having a vertical shank which is capable of puncturing the skin of a patient and extending into the fluid chamber of the subcutaneous device. An arm is connected to the needle shank through a generally right angled bend and has a fitting adapted for connection to a source of fluid to be introduced into or removed from the chamber of the subcutaneous catheter assembly. A mounting jacket is affixed to the perpendicularly located arm and has a section which extends over the fitting on the end of the arm as well as an integrally formed surface section extending outwardly therefrom and which is capable of being secured to the of the patient by means of a suitable surgical tape or the like. In this way, the needle device can be affixed to the patient for long term use, as for example, intravenous feeding, without the attendant danger of injury to the patient by inadvertent contact with an extended end of the needle device.
