INTEGRATED ULTRASOUND IMAGING DEVICE WITH PULSE OXIMETER WAVEFORM DISPLAY FOR APPLICATION OF REGIONAL ANESTHESIA

摘要

The various embodiments of the present invention provide an integrated ultrasound imaging device with pulse oximeter waveform display for application of regional anesthesia. The device has an ultrasound probe (11) and a Saturation of Hemoglobin with Oxygen as measured by Pulse Oximetry (SpO2) probe (12) connected to a display unit (15) through a beam former (13) and a pulse oximeter (14) respectively. A processor (40) is connected to the ultrasound probe (11), the SpO2 probe (12) and the display unit (15) to receive the output signals from the ultrasound probe (11) and the SpO2 probe (12) to display a real time ultrasound image of the scanned area and the measured SpO2 values on the same display unit (15). It provides a color doppler imaging mode to differentiate between the nerves and blood vessels to avoid puncture the blood vessel.
