Lubricant Regulating Agent

Abstract

The present invention makes the insertion perception during actual surgery to be equivalent to the insertion perception of a catheter into a blood vessel model when water is used as the circulating fluid. A lubricant regulating fluid primarily composed of water is mixed with an aqueous metal salt and a surfactant as a lubricant regulating agent of the lubricant regulating fluid. A cationic surfactant, an anionic surfactant, a nonionic surfactant, or a dipolar ionic surfactant may be used as the surfactant. Also, the metal salt may be an alkaline metal salt, an alkaline earth metal salt, an aluminum salt, a ferric salt, or the like. In an example, the lubricant regulating fluid obtained by mixing an aqueous metal salt with water is prepared, and the lubrication and non-adherent properties of a catheter into a simulated blood vessel model are improved.

1 . A circulating liquid to be filled in a blood vessel model for a catheter simulator made of silicone rubber, comprising:
 water;   a surfactant; and   a water-soluble ion compound.   
     
     
         2 . The circulating liquid according to  claim 1 , wherein the ion compound is a metal salt. 
     
     
         3 . The circulating liquid according to  claim 1 , wherein the silicone rubber is a blood vessel model for catheter simulation. 
     
     
         4 . The circulating liquid according to  claim 2 , wherein the surfactant is one or two or more selected from the group consisting of a cationic surfactant, an anionic surfactant, a nonionic surfactant and a zwitterionic surfactant. 
     
     
         5 . The circulating liquid according to  claim 4 , wherein the ion compound is one or two or more selected from the group consisting of an alkali metal salt, an alkali earth metal salt, an aluminum salt and an iron salt. 
     
     
         6 . The circulating liquid according to  claim 4 , wherein the surfactant comprises at least a cationic surfactant.
