Needle device for use with subcutaneous catheter assemblies
First Claim
1. A needle device adapted for use with a subcutaneous implanted assembly having a fluid reservoir, said device comprising:
- (a) a tubular needle shank of the type used with a subcutaneous implanted fluid reservoir and having a tip portion adapted to extend through the skin and into the fluid reservoir, said shank having a bore through which fluid may enter or be withdrawn from said reservoir;
(b) a tubular arm angularly located with respect to said shank and being integrally connected to said shank, said arm having a bore in fluid communication with the bore of said shank,(c) a mounting jacket extending partially around a portion of said arm and being secured to said arm, said jacket extending outwardly transversely from said arm and which is capable of being flatwise disposed on the surface of the skin adjacent to the region where the shank penetrates the skin so that tape may be adhesively secured to the jacket and to the skin to retentively hold the needle device in a fixed position onto the user without the necessity of independently tapeing the arm to the user'"'"'s skin, and(d) an upstanding section on said jacket and being substantially rigid so that it can be grasped by an attendant with one hand and positioned with respect to a user and properly maneuvered to insert the tip portion through the user'"'"'s skin and into the fluid reservoir.

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.

13. A needle device adapted for use with a subcutaneously implanted assembly having a fluid reservoir, said device comprising:
-
(a) a tubular needle shank of the type used with a subcutaneous implanted fluid reservoir and having a tip portion adapted to extend through the skin and into the fluid reservoir, said shank having a bore through which fluid may enter or be withdrawn from said reservoir, (b) a tubular arm angularly located with respect to said shank and being integrally connected to said shank, said arm having a bore in fluid communication with the bore of said shank, and (c) a mounting jacket extending partially around a portion of said arm and being secured to said arm, said jacket extending outwardly transversly from said arm and which is capable of being flatwise disposed on the surface of the skin adjacent to the region where the shank penetrates the skin so that tape may be adhesively secured to the jacket and to the skin to retentively hold the needle device in a fixed position onto the user without the necessity of independently tapeing the arm to the users skin, said jacket being configured so that it can be grasped by an attendant and positioned with respect to a user and properly maneuvered to insert the tip portion through the users skin and into the fluid reservoir. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
