Assignee:

Luther M. King - Grapeland TX

International Classification:

A61M 136

US Classification:

422 44, 422 46, 2101951, 210260, 604 613, 604113, 165261

Abstract:

A blood heating system for use in open heart surgery including an arterial/venous fluid circuit, a cardioplegia fluid circuit independent of the arterial/venous fluid circuit, a first heater in heat exchange relationship with the arterial/venous fluid circuit, a second heater in heat exchange relationship with the cardioplegia fluid circuit, a power supply connected to the first and second heaters so as to supply a desired electrical power, to the first and second heaters, and a controller electrically interconnected to the power supply and to the first and second heaters such that the first and second heaters cannot be activated simultaneously. A relay is electrically interconnected between the first and second heaters and the power supply so as to deactivate one of the heaters when the other of the heaters is activated. A timer is connected to the relay so as to alternately activate and deactivate the respective heaters after a desired period of time.

Inventors:

- College Station TX, US
William STEWART - College Station TX, US
Douglas PLATT - College Station TX, US
Jon Lowrey GARDNER - College Station TX, US

Assignee:

CardioQuip, LLC - College Station TX

International Classification:

G01N 21/59
G01N 21/33
G01N 33/18

Abstract:

A water monitoring system comprising a hydrogen peroxide sensor configured to determine a concentration of hydrogen peroxide in water in a conduit. The hydrogen peroxide sensor further comprises an ultraviolet light sensor configured to determine an ultraviolet light absorbance level of the water in the conduit. The ultraviolet light absorbance level is used to determine the concentration of hydrogen peroxide. The hydrogen peroxide sensor may further comprise a visible light sensor configured to determine a turbidity level of the water in the conduit. The turbidity level also is used to determine the concentration of hydrogen peroxide.
