BLOOD VOLUME MONITOR

摘要

A blood volume monitor includes a carrier mountable on a subject's body part. A measuring arrangement is mounted on the carrier. The measuring arrangement provides data relating to a change in volume of the body part, and outputs signals representative of the change. A control unit is in communication with the measuring arrangement to process data output by the measuring arrangement to determine, using the volume data, the volume of the body part and determines blood volume in the body part. The control unit uses the response signals received from the measuring arrangement and the determined volume of the part of the body to determine the blood volume.

1. A blood volume monitor comprising:
a carrier mountable about a part of a body of a subject; an array mounted on the carrier, the array comprising at least one volume sensor configured to provide volume data relating to a volume of the part of the body of the subject underlying the carrier and configured to measure change in volume of the part of the body of the subject underlying the carrier and configured to output response signals representative of the change in volume; and a controller in communication with the array, configured to process data output by the array to determine, using the volume data, the volume of the part of the body of the subject underlying the carrier and to determine blood volume in the part of the body of the subject, the controller configured to use the response signals received from the array and the determined volume of the part of the body to determine the blood volume.
