Patent number: 10743776Abstract: A system for measuring the blood loss comprises a measuring device that determines a hemoglobin concentration of fluid within a container utilizing a light source and a light detector. The container receives blood and other fluids from a patient during a medical procedure. Light from the light source is passed through the blood and other fluids in the container and is detected by the light detector. Based upon a magnitude of light detected, a hemoglobin concentration of the fluid in the container can be determined. A volume-measuring device determines the volume of blood and fluid in the container. Knowing the hemoglobin concentration and volume of fluid in the container, the volume of patient blood loss in the container can be determined. The blood loss measuring device in combination with infusion systems maintains a real-blood volume status so that proper infusion of blood, crystalloid and/or colloid solutions occurs.Type: GrantFiled: May 13, 2019Date of Patent: August 18, 2020Assignee: MAJELCO MEDICAL, INC.Inventors: Alfred Akerman, Stephen W. Allison, Matthew B. Scudiere, Michael R. Cates, David L. Beshears, Lara M. Brewer Cates, Adan James Akerman, Annette MacIntyre

Patent number: 6123455Abstract: An apparatus for measuring the temperature of a moving substrate includes an air gun with a powder inlet port in communication with the outlet port of a powder reservoir, an air inlet port in communication with a pressurized air source, and an outlet nozzle spaced from and directed toward the moving substrate. The air gun is activated by the air pulses to spray controlled amounts of the powdered phosphor onto the moving substrate, where the phosphor assumes the temperature of the moving substrate. A laser produces light pulses, and optics direct the light pulses onto the phosphor on the moving substrate, in response to which the phosphor emits a luminescence with a decay rate indicative of the temperature of the phosphor. A collection lens is disposed to focus the luminescence, and a photodetector detects the luminescence focused by the collection lens and produces an electrical signal that is characteristic of the brightness of the luminescence.Type: GrantFiled: May 2, 1997Date of Patent: September 26, 2000Assignee: American Iron and Steel InstituteInventors: David L. Beshears, David N. Sitter, Jr., William H. Andrews, Marc L. Simpson, Ruth A. Abston, Michael R. Cates, Steve W. Allison

Patent number: 5986272Abstract: A method for determining the temperature of a fluorescing phosphor is provided, together with an apparatus for performing the method. The apparatus includes a photodetector for detecting light emitted by a phosphor irradiated with an excitation pulse and for converting the detected light into an electrical signal. The apparatus further includes a differentiator for differentiating the electrical signal and a zero-crossing discrimination circuit that outputs a pulse signal having a pulse width corresponding to the time period between the start of the excitation pulse and the time when the differentiated electrical signal reaches zero. The width of the output pulse signal is proportional to the decay-time constant of the phosphor.Type: GrantFiled: April 19, 1999Date of Patent: November 16, 1999Assignee: American Iron and Steel InstituteInventors: Charles L. Britton, Jr., David L. Beshears, Marc L. Simpson, Michael R. Cates, Steve W. Allison
