Continuous optoacoustic monitoring of hemoglobin concentration and hematocrit |
摘要 |
An optoacoustic apparatus is disclosed which includes a radiation source of pulsed optical radiation and a probe having a front face to be placed in contact with a tissue site of an animal body. The probe further includes an optical fiber terminating at the surface of the front face of the probe and connected to a pulsed laser. The front face of the probe also has mounted therein or thereon a piezoelectric transducer for detecting an acoustic response to the radiation pulses connected to a processing unit which converts the transducer signal into a measure of hemoglobin concentration and/or hematocrit of blood.
