  • Publication number: 20210282390
    Abstract: A perfusion lumen is connected to at least one perfusion blood vessel among a plurality of blood vessels that extends from a branch of a plurality of blood vessels protruding from a liver, the branch existing on a distal side viewed from the liver, to a further distal side viewed from the liver. The perfusion lumen is supplied with perfusate to perfuse the liver and maintain the condition of the liver. Among blood vessels that are not connected to the perfusion lumen, at least one conserved blood vessel is obstructed and conserved for anastomosis to a blood vessel of the living body. Accordingly, the perfusion state of the liver is maintained even during anastomosis to the blood vessels of the living body. This enables anastomosis to the blood vessels of the living body while maintaining the perfusion state of the liver.

  • Patent number: 10365368
    Abstract: An object detecting device includes a detector and a determination unit. The detector detects presence or absence of an object based on whether a receiving unit that converts a mechanical vibration into an electric signal receives a reflected ultrasonic wave transmitted intermittently from a transmitting unit. The determination unit determines that the transmitting unit is normal when the electric signal is not detected in a determination section set within a predetermined time from a starting time point of the transmission of the ultrasonic wave. The determination unit determines that the transmitting unit is abnormal when a correlation value of waveforms of a plurality of electric signals detected in the plurality of determination sections is greater than or equal to a specified value. The determination unit determines that the transmitting unit is normal when the correlation value is less than the specified value.
