Abstract

Provided is a fluid wicking tip. The fluid wicking tipi includes a plurality of drip flanges arranged to wick fluid between narrow spaces defined between any two drip flanges. The narrow spaces are dimensioned to facilitate wicking by capillary action. Also provided is a syringe that includes the fluid wicking tip. Also provided is a modular syringe system that includes a syringe and a sleeve configured to be slidably disposed over the syringe.

First claim

1 . A fluid wicking tip, comprising a plurality of drip flanges arranged to wick fluid into narrow spaces defined between any two adjacent drip flanges, wherein the narrow spaces are dimensioned to facilitate wicking by capillary action.

2 . The fluid wicking tip of claim 1 , wherein the drip flanges are arranged in at least two tiers.

3 . The fluid wicking tip of claim 2 , wherein the at least two tiers have a different diameter.

4 . The fluid wicking tip of claim 3 , wherein a top tier, distal-most drip flange has a smaller diameter than a lower tier proximal drip flange.

5 . The fluid wicking tip of claim 3 , wherein a top tier, distal-most drip flange has a larger diameter than a lower tier proximal drip flange.

6 . The fluid wicking tip of claim 2 , wherein a top tier, distal-most drip flange has the same diameter as any lower tier drip flange.

7 . The fluid wicking tip of claim 1 , further comprising a drip cup positioned distal to the plurality of drip flanges.

8 . The fluid wicking tip of claim 1 , further comprising a drip cup positioned proximal to the plurality of drip flanges.

9 . The fluid wicking tip of claim 1 , wherein the plurality of drip flanges are flat and smooth and continuous.

10 . The fluid wicking tip of claim 1 , wherein the plurality of drip flanges are staggered relative to each other.

11 . The fluid wicking tip of claim 1 , wherein the plurality of drip flanges are ruffled.

12 . The fluid wicking tip of claim 1 , further comprising a piercing tip fluidly coupled thereto.

13 . The fluid wicking tip of claim 1 , wherein the plurality of drip flanges each comprises an opening to facilitate draining of fluid from a distal drip flange to a more proximately located drip flange.

14 . The fluid wicking tip of claim 1 , further comprising a luer fitting sized and configured to fluidly couple to a syringe.

15 . The fluid wicking tip of claim 1 , further comprising a luer fitting sized and configured to fluidly couple to a flexible tube assembly.

16 . A syringe, comprising:
a body defining a cylindrical fluid chamber having a distal end and a proximal end, a tapered portion extending from the distal end of the cylindrical fluid chamber, and a tip extending from the tapered portion; and fluid wicking tip fluidly coupled to the tip of the syringe.

17 . The syringe of claim 16 , further comprising a piercing tip fluidly coupled to the fluid wicking tip.

18 . The syringe of claim 16 , wherein the fluid wicking tip is integrally formed with an outer surface of the tapered portion of the distal end.

19 . A modular syringe system, comprising:
a syringe comprising a body defining a cylindrical fluid chamber having a distal end and a proximal end, a tapered portion extending from the distal end of the cylindrical fluid chamber, and a tip extending from the tapered portion; and a sleeve configured to be slidably disposed over the cylindrical portion of the body and fit in one of a rotational locking arrangement and a friction fit arrangement with the cylindrical portion of the body.

20 . The modular syringe system of claim 19 , wherein the sleeve further comprises a plurality of drip flanges disposed about an outer circumference of the sleeve.
