Abstract

An improved method for formulating a couplant for transmission of ultrasound therapy or sonic imaging consisting of a super absorbent polymer which rapidly hydrates when added to water thus allowing transmission of ultrasonic therapy or sonogram imaging when resulting hydrated polymer gel is applied to the skin of a mammal, and the appropriate ultrasonic or sonogram imaging device is used.

Claims

1. An improved method of providing a couplant allowing the transmission of ultrasonic or sonogram images consisting essentially of:

a rapid hydrating super absorbent acrylamide/sodium acrylate copolymer concentrate suspended in medical grade mineral oil with an active content of about 57.5 percent with a viscosity as supplied 400-1,400 cps (Brookfield LVT sp.3;

30 rpm) and a viscosity in a 1 percent solution of 10,000-15,000 cps (Brookfield RVT sp 6;

50 rpm) and a pH in a 1 percent solution of 5.8-6.2 having the ability to hydrate in tap water with a pH of about 4.8 to 8.2 within five minutes after combining the water and the copolymer concentrate and requiring no additional thickeners, preservatives or ingredients.
