Abstract
Abstract A needle and hub unit having a beveled needle or canula point for insertion into a patient, the unit having indicia thereon indicating the orientation of the beveled insertion point; and a method and apparatus of orienting the marketing such beveled needle units by combined vibrational and camming of the canula and thereupon marking the assembled unit.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
70 words
The method of forming an oriented bevel needle unit comprising, inserting a bevel-pointed canula into a guide orifice vibrating said canula in said guide orifice and against a rotation-effecting camming surface to exert a rotational force thereon to bring the bevel point of said canula into a desired rotationally oriented position, securing said canula to a hub, and marking said unit to indicate the angular position of said bevel point.
Claim 2
Independent Claim
70 words
The method of forming an oriented bevel needle unit comprising, inserting a bevel-pointed canula into a guide orifice vibrating said canula in said guide orifice and against a rotation-effecting camming surface to exert a rotational force thereon to bring the bevel point of said canula into a desired rotationally oriented position, securing said canula to a hub, and marking said unit to indicate the angular position of said bevel point.
Claim 3
Dependent Claim
22 words
The method according to claim 1, said canula being inserted into an upstanding guide orifice within which is disposed said camming surface.
Claim 4
Dependent Claim
41 words
The method according to claim 2, said rotational force being exerted on said needle as a component of an upwardly slanted reaction force resulting from vibrational contact of the beveled butt end of said needle with an upwardly facing camming surface.
Claim 5
Dependent Claim
45 words
The method according to claim 3, said upwardly extending camming surface being substantially flat and of substantially constant affective inclination to the horizontal and the vertical and being inclined to substantially the same angle as the angle of the beveled butt end of said canula.
Claim 6
Dependent Claim
35 words
The method according to claim 3, said upwardly facing camming surface being formed by an upstanding knife edge disposed off-center with respect to the longitudinal axis of said canula during contact of said canula therewith.
Claim 7
Dependent Claim
64 words
The method according to claim 2, further comprising retaining said hub on an upstanding male guide while downwardly inserting said canula loosely through said male guide and into said guide orifice, and thereafter effecting crimping of said hub and oriented bevel-pointed canula onto said canula and marking the exterior of said hub to indicate the angular position of the bevel forming said bevel point.
Claim 8
Independent Claim
56 words
The method of forming an oriented bevel needle unit comprising, inserting a bevel-pointed canula into a guide vibrating said canula in said guide and against a rotation-effecting camming surface to exert a rotational force thereon to bring the bevel point of said canula into a desired rotationally oriented position, and securing said canula to a hub.
Claim 9
Independent Claim
56 words
The method of forming an oriented bevel needle unit comprising, inserting a bevel-pointed canula into a guide vibrating said canula in said guide and against a rotation-effecting camming surface to exert a rotational force thereon to bring the bevel point of said canula into a desired rotationally oriented position, and securing said canula to a hub.
Claim 10
Dependent Claim
37 words
A method according to claim 7, said canula being inserted into an upstanding guide, said vibrating said canula against said rotation-effecting camming surface by contact therewith at a position disposed beneath the upper extent of said guide.
