Abstract:
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.

Claim (Index 18):
A blood loss measurement device for determining an amount of blood of a patient within a fluid sample, the fluid sample having a volume, the blood measurement device comprising:\n a container configured to receive blood from a patient during a medical procedure; a plurality of light sources, each configured to generate light at a wavelength different from the other plurality of light sources; at least one light sensor configured to detect a first amount of light from the plurality of light sources and to generate a signal of the first amount of light; a plurality of optical fibers comprising:\n a first plurality of optical fibers each having a first end coupled to at least one of the plurality of light sources and a second end opposite the first end configured to be disposed within the container proximate a bottom of the container; and \n a second optical fiber having a first end proximate to and spaced a distance from the second end of the first optical fiber and positioned to receive light from the first optical fiber and a second end coupled to the at least one light sensor, wherein light emanating from the first optical fiber is a least partially received by the second optical fiber, the amount of light received by the second optical fiber being detected by the at least one light sensor to determine an amount of light received by the second optical fiber from the first optical fiber; \n a processor operatively coupled to the at least one light sensor, the processor configured to receive the signal from the at least one light sensor, the signal being dependent upon an amount of absorption of light by blood in the container disposed between the first optical fiber and the second optical fiber and the processor determining a concentration of blood in the container depending on the signal; and a volume detection device for continually detecting a volume of fluid in the container as fluid is added to the fluid sample.
