Abstract

A method of constructing an infusion set, patch pump, or element thereof, comprising the steps of mixing at least two of a solvent, an anesthetic, and a lubricant, applying said mixture as a coating to at least one surface of an infusion set, patch pump, or element thereof, and substantially removing said solvent after coating to provide at least one of an anesthetic layer and a lubricant layer upon said infusion set, patch pump, or element thereof.

First claim

What is claimed is:

1 . A method of constructing an infusion set, patch pump, or element thereof, comprising the steps of:
mixing at least two of a solvent, an anesthetic, and a lubricant; applying said mixture as a coating to at least one surface of an infusion set, patch pump, or element thereof; and substantially removing said solvent after coating to provide at least one of an anesthetic layer and a lubricant layer upon said infusion set, patch pump, or element thereof.

2 . A method of constructing an infusion set, patch pump, or element thereof, as recited in claim 1 , wherein said step of mixing comprises mixing at least two of:
a polymer solvent; an anesthetic compound, comprising at least one of amino esters, amino amides, and other anesthetic compounds; a lubricant material; an anti-microbial material; and an anti-inflammatory material.

3 . A method of constructing an infusion set, patch pump, or element thereof, as recited in claim 1 , wherein said step of applying said mixture comprises at least one of:
a spraying step wherein said mixture is sprayed onto a surface of said infusion set, patch pump, or element thereof; a dipping step wherein said infusion set, patch pump, or element thereof is dipped into said mixture; and an inkjet printing step wherein said mixture is inkjet printed onto a surface of said infusion set, patch pump, or element thereof.

4 . A method of constructing an infusion set, patch pump, or element thereof, as recited in claim 1 , wherein said step of removing said solvent comprises:
an evaporation step for allowing said solvent to evaporate from said coated infusion set, patch pump, or element thereof.

5 . A method of constructing an infusion set, patch pump, or element thereof, as recited in claim 1 , wherein said at least one of said anesthetic layer and said lubricant layer is provided as a skin-contacting adhesive of said infusion set, patch pump, or element thereof configured to release said anesthetic at an infusion site.

6 . A method of constructing an infusion set, patch pump, or element thereof, as recited in claim 1 , wherein the at least one of said anesthetic layer and said lubricant layer is provided as an external coating of a catheter of said infusion set, patch pump, or element thereof configured to release said anesthetic at any point between an infusion site and a catheter termination site within said insertion site.

7 . A method of constructing an infusion set, patch pump, or element thereof, as recited in claim 1 , wherein the at least one of said anesthetic layer and said lubricant layer is provided as an internal coating of said infusion set, patch pump, or element thereof configured to release said anesthetic at a catheter termination site within said insertion site.

8 . A method of constructing an infusion set, patch pump, or element thereof, as recited in claim 1 , wherein the at least one of said anesthetic layer and said lubricant layer upon said infusion set, patch pump, or said element thereof is provided in a biocompatible polymer coating, such as a hydrogel, configured to release said anesthetic over a period of time.

9 . A method of constructing an infusion set, patch pump, or element thereof, as recited in claim 1 , wherein said anesthetic layer and said lubricant layer comprise an anesthetic within a polydialkylsiloxane lubricant compound.

10 . A method of constructing an infusion set, patch pump, or element thereof, as recited in claim 9 , wherein the step of mixing comprises:
mixing said polydialkylsiloxanes with an organic solvent comprising at least one of aliphatic hydrocarbons, methylene chloride, and other chlorinated solvents; and dissolving said anesthetic in said solvent/polydialkylsiloxane mixture.

11 . A method of constructing an infusion set, patch pump, or element thereof, as recited in claim 1 , wherein the step of mixing comprises mixing said anesthetic with at least one of an aqueous and bioerodible polymer formulation.

12 . A method of applying or administering an anesthetic at an infusion site, comprising the steps of:
providing at least one of a hub, catheter or cannula of an infusion set or patch pump with an anesthetic; and affixing the infusion set or patch pump to the skin of a patient to release the anesthetic at an insertion site of said catheter or cannula.

13 . A method of applying or administering an anesthetic at an infusion site as claimed in claim 12 , wherein said anesthetic is provided in a biocompatible polymer coating, such as a hydrogel, configured for release at said insertion site over time.

14 . A method of applying or administering an anesthetic at an infusion site as claimed in claim 12 , wherein said anesthetic is provided as a skin-contacting, adhesive layer disposed upon an outer surface of said hub for release at said insertion site.

15 . A method of applying or administering an anesthetic at an infusion site as claimed in claim 12 , wherein said anesthetic is provided as a layer disposed upon an inner surface of said hub, catheter or cannula for release at a termination site within said insertion site.

16 . A method of applying or administering an anesthetic at an infusion site as claimed in claim 12 , wherein said anesthetic is provided as a construction material of said hub, catheter or cannula for release at both said insertion site and a termination site within said insertion site.

17 . A method of applying or administering an anesthetic at an infusion site as claimed in claim 12 , wherein said anesthetic comprises an anesthetic within a polydialkylsiloxane lubricant compound.

18 . A method of applying or administering an anesthetic at an infusion site as claimed in claim 12 , wherein said anesthetic comprises at least one of amino esters, amino amides, and other anesthetic compounds.

19 . A method of applying or administering an anesthetic at an infusion site as claimed in claim 12 , wherein said at least one surface of said hub, catheter or cannula is further provided with at least one of a lubricant material, an anti-microbial material, and an anti-inflammatory material with said anesthetic.
