1. A needle device comprising:
- a rigid tubular needle assembly having an insertion section disposed angularly with respect to an inlet section, anda housing enclosing said angularly disposed sections with the end of said insertion section protruding exteriorly from said housing, said housing having internal angularly disposed confinement means coacting in engagement with said angularly disposed inlet and insertion sections to immobilize said needle assembly in relation to said housing, said housing being subdivided into multiple releasably coupled components which may be separated one from the other to accommodate removal of said housing from said needle, said confinement means being located at interfaces between said components.

11. A needle device comprising:
-
a needle having a proximal end adapted to connect to a flexible tube, a sharpened distal end adapted to be inserted into a subject, and mutually angularly disposed segments between said ends, and a housing enclosing said angularly disposed segments with the sharpened distal end of said needle protruding exteriorly from said housing, said housing having stabilizing means for preventing said needle from rotating about either of the axes defined by each of said angularly disposed segments, said housing being subdivided into multiple releasably coupled components which may be separated one from the other to accommodate removal of said housing from said needle without requiring removal of said proximal end from said tubing or removal of said distal end from said subject.

12. A needle device comprising:
-
a tubular needle assembly having an insertion section disposed angularly with respect to an inlet section, and a housing enclosing said angularly disposed sections with the end of said insertion section protruding exteriorly from said housing, said housing having internal engagement means for coacting with said sections to immobilize said needle in relation to said housing, said housing being subdivided into multiple releasably coupled components which may be separated one from the other to accommodate removal of said housing from said needle, wherein said releasably coupled components include resilient locking members for releasably locking said components together in a snap fit engagement.

13. A needle device comprising:
-
a rigid tubular needle assembly having an insertion section disposed angularly with respect to an inlet section, and a housing enclosing said angularly disposed sections with the end of said insertion section protruding exteriorly from said housing, said housing having immobilizing means for immobilizing said needle thereby preventing said needle from rotating about either of the axes defined by each of said angularly disposed sections, said housing being subdivided into multiple releasably coupled components which may be separated one from the other to accommodate removal of said housing from said needle.
