Abstract
An elongated tubular needle for injecting a fluid into a human body or retracting a fluid from the human body, comprising; a tubular needle cannula (1) having a skin piercing distal end (4), an opposite proximal end (5), and a tubular sidewall (2) there between having an outside diameter at the skin piercing end (4) which is smaller than the outside diameter at the opposite proximal end (5) thereof, and a cylindrical lumen (3) extending through the needle cannula (1) and having approximately the same uniform inside diameter through the needle cannula (1).
Claims (14)
1. An elongated tubular needle cannula (1) for injecting a fluid into a human body or retract-ing a fluid from the human body, comprising;
a skin piercing distal end (4), an opposite proximal end (5) and a side wall (2) there between, a lumen (3) extending through said needle cannula (1) from the skin piercing distal end (4) to the opposite proximal end (5) along a longitudinal axis of said needle cannula (1), said nee-dle cannula (1) having an outside diameter at the skin piercing distal end (4) which is smaller than the outside diameter at the opposite proximal end (5), Characterized in that, the longitudinal lumen (3) is cylindrical and has approximately the same uniform inside di-ameter through said needle cannula (1) from the skin piercing distal end (4) to the opposite proximal end (5).
a skin piercing distal end (4), an opposite proximal end (5) and a side wall (2) there between, a lumen (3) extending through said needle cannula (1) from the skin piercing distal end (4) to the opposite proximal end (5) along a longitudinal axis of said needle cannula (1), said nee-dle cannula (1) having an outside diameter at the skin piercing distal end (4) which is smaller than the outside diameter at the opposite proximal end (5), Characterized in that, the longitudinal lumen (3) is cylindrical and has approximately the same uniform inside di-ameter through said needle cannula (1) from the skin piercing distal end (4) to the opposite proximal end (5).
2. An elongated tubular needle cannula according to claim 1, characterized in that, the out-side sidewall (2) is conically tapered towards the skin piercing distal end (4).
3. An elongated tubular needle cannula according to claim 1, characterized in that, the out-side sidewall (2) comprises two elongated tubular portions (6, 7) interfacing each other in a peripheral transition zone (8), namely a first elongated tubular portion (6) extending from the peripheral transition zone (8) to the skin piercing distal end (4) of said needle cannula (1), and a second tubular portion (7) extending from the peripheral transition zone (8) to the op-posite proximal end (5) of said needle cannula (1).
4. An elongated tubular needle cannula according to claim 3, characterized in that, the first elongated tubular portion (6) is conically tapered from the peripheral transition zone (8) to the skin piercing distal end (4), and that the second portion (7) has approximately the same uniform outside diameter from the peripheral transition zone (8) to the opposite proximal end (5) of said cannula (1).
5. An elongated tubular needle cannula according to anyone of the claims 1 to 4, character-ized in that the skin piercing distal end (4) has an outside diameter equal to or smaller than a G 31 needle, the opposite proximal end (5) has an outside diameter equal to or larger than a G 30 needle, and the longitudinal lumen (3) has an uniform inside diameter equal to or larger than the inside diameter of a G 30 needle.
