Abstract

A needle device includes a multi-component housing assembled about a needle having angularly disposed segments. The housing immobilizes the needle during insertion and is adapted for subsequent disassembly and removal from the needle.

Claims

1. 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 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.

2. A device as claimed in claim 1, wherein said components include cavities for receiving said insertion and inlet sections.

3. A device as claimed in claim 2, wherein said components further include surfaces coacting with said cavities to capture said sections.

4. A device as claimed in claim 1, wherein said angularly disposed sections are disposed at a substantially right angle to one another.

5. A device as claimed in claim 1, wherein said releasably coupled components are releasably coupled along a linear direction defined by said inlet section of said tubular needle assembly.

6. A device as claimed in claim 1, wherein said releasably coupled components include resilient locking members for releasably locking said components together in a snap fit engagement.

7. A device as claimed in claim 1, wherein said housing includes a gripping portion on a side of said housing for facilitating manual control and manipulation of said assembly.

8. A device as claimed in claim 7, wherein said gripping portion includes a concave surface.

9. A device as claimed in claim 1, wherein said device further includes a flexible tube having a distal end connected to an inlet section of said needle.

10. A device as claimed in claim 9, wherein said device further includes a luer connector attached to a proximal end of said flexible tube.

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.
