Abstract

An exemplary insulin infusion set that further provides one or more set elements including the hub, hub adhesive, fluid line tubeset, connectors, catheters and insertion needles which can be impregnated with, coated with, or otherwise configured to contain and administer an anesthetic at the insertion and set placement locations to minimize user discomfort and the risk of complications associated with the use of infusion sets. To do so, the system and method provides steps for mixing at a step (22) at least two of a solvent, an anesthetic, and a lubricant, applying the mixed compound as a coating to at least one surface of the infusion set, patch pump, or an element thereof at a step (24), and then substantially removing the solvent after coating at a step (26) to provide at least one of an anesthetic layer and a lubricant layer upon the infusion set, patch pump, or an element thereof.

Claims

1. An infusion set configured to apply or administer an anesthetic, comprising:

a hub,

a catheter connected to said hub, and

an anesthetic coating comprising an anesthetic and a coating, the anesthetic coating disposed on at least one inner surface of said hub or catheter,

wherein infusate flowing through said infusion set to a catheter insertion site contacts said at least one inner surface of said hub or catheter, and

wherein said coating remains on said inner surface of said hub or catheter and releases the anesthetic to said infusate over a period of time during use of said infusion set.

2. An infusion set configured to apply or administer an anesthetic as claimed in claim 1, wherein said coating comprises a biocompatible polymer coating, such as a hydrogel.

3. An infusion set configured to apply or administer an anesthetic as claimed in claim 1, wherein a second anesthetic coating is provided as a skin-contacting, adhesive layer on an outer surface of said hub.

4. An infusion set configured to apply or administer an anesthetic as claimed in claim 1, wherein an anesthetic is provided as part of a construction material of said hub or catheter.

5. An infusion set configured to apply or administer an anesthetic as claimed in claim 1, wherein said coating comprises a polydialkylsiloxane lubricant.

6. An infusion set configured to apply or administer an anesthetic as claimed in claim 1, wherein said anesthetic comprises at least one of amino esters and amino amides.

7. An infusion set configured to apply or administer an anesthetic as claimed in claim 1, wherein at least one surface of said hub or catheter is provided with an anesthetic combined with at least one of a lubricant material, an anti-microbial material, and an anti-inflammatory material.

8. An infusion set configured to apply or administer an anesthetic as claimed in claim 1, wherein said infusion set further comprises a fluid tube set having at least one surface provided with an anesthetic combined with at least one of a lubricant material, an anti-microbial material, and an anti-inflammatory material.
