114 results about "Fluid replacement" patented technology

Fluid replacement or fluid resuscitation is the medical practice of replenishing bodily fluid lost through sweating, bleeding, fluid shifts or other pathologic processes. Fluids can be replaced with oral rehydration therapy (drinking), intravenous therapy, rectally such as with a Murphy drip, or by hypodermoclysis, the direct injection of fluid into the subcutaneous tissue. Fluids administered by the oral and hypodermic routes are absorbed more slowly than those given intravenously.

Test for brake fluid age and condition

A correlation is derived between a variable, defined as "virtual age," indicative of brake fluid's service age and / or mileage and the concentration of copper in the fluid. Virtual age is utilized to estimate the degree of degradation of the fluid. A reactive test strip is used to measure the concentration of copper ions in the brake fluid in terms of a readily visible color change. The strip is immersed in the fluid and any resulting color change is compared to a color chart and a standard representative of the maximum concentration determined empirically to correspond to the desirable "virtual-age" threshold for fluid replacement. An automated embodiment of the invention includes an optical instrument to compare the color obtained from the test to a predetermined standard and determine whether a fluid change is recommended.
