An adhesion promotion device is disclosed, which is capable of reducing risk factors of an anastomotic leakage after surgery. The adhesion promotion device has a main body portion disposed between biological organs serving as a joint object. The main body portion has a first region and a second region formed along an outer edge of the first region. The second region includes an adhesion promotion portion that promotes adhesion of a biological tissue. The first region includes a holding portion having a holding force with respect to the biological tissue which is stronger than that of the adhesion promotion portion.

Adhesion promotion device

An extracorporeal blood circulation system monitors blood level in a reservoir which temporarily stores the blood. A memory storage unit stores blood pressure measurements from a pressure sensor monitoring a blood pressure within a tube unit conveying blood from the reservoir relative to atmosphere. A processing unit that detects a height of a top surface of the blood stored in the reservoir based on changes in the blood pressure measurements and a conservation of mechanical energy of a blood flow inside the tube unit. A notification is generated if an abnormality is detected in the height of the blood in the reservoir.

Extracorporeal circulation management device with blood level detection in a reservoir without a sensor

An extracorporeal circulation apparatus has a blood reservoir temporarily storing blood and a presence information acquisition unit to detect presence or absence of blood at respective wall locations in a two-dimensional array. A control unit determines the position of a blood surface on the basis of consecutive elements in the array having detected blood along at least one of a first direction parallel to the blood surface and a second direction perpendicular to the blood surface.

Extracorporeal circulation apparatus

An extracorporeal circulation management device pumps blood in synchronization with heartbeats of a patient based on measurements of blood flow. Maximum and minimum blood flow measurement samples are compared with upper and lower threshold values to identify candidate timing for a systolic phase and diastolic phase of the heartbeat. During pulsatile pumping of the blood using the candidate timing, differences in the pulsatile flow measurements are determined. Based on the size of the difference, a final correction may be made to identification of the systolic and diastolic phases, and the corrected phase information is used to start and stop the motor unit.

Extracorporeal circulation management device with heartbeat synchronizaton

An extracorporeal blood circulation system reduces the risk of generation of air bubbles entering the circulation circuit associated with placement of a pressure sensor that detects a patient's blood pressure at a blood removal line. Instead of directly measuring pressure at the blood removal line where suction exists, an intermediate part pressure sensor detects pressure between a centrifugal pump and an oxygenator. A controller identifies a discharge pressure specific to the centrifugal pump based on a rotation speed of the pump and a blood flow rate. The discharge pressure and the intermediate pressure values are combined to estimate the pressure at the blood removal line.
