Abstract: An artificial heart and lung apparatus includes a roller pump; a blood removal line; a first blood transfer line; a blood removal rate sensor; a control unit that performs the linked control of the roller pump in correspondence with a blood removal rate; and a blood transfer rate adjustment unit that instructs the roller pump to transfer a blood transfer rate. The blood transfer rate adjustment unit includes an operation amount input unit to which an operation amount from an arbitrary circumferential position can be input, and which outputs a pulse signal according to the input operation amount. A counter adds and subtracts pulse signals output from the operation amount input unit, and outputs a resultant as blood transfer rate adjustment data. The counter performs a counting operation with respect to the circumferential position of the operation amount input unit when blood transfer control transitions to the normal control.

Abstract: An air leak detection device is applied to a thoracic cavity drainage system which, by using negative pressure generated by a vacuum source, aspirates gas in the thoracic cavity of a patient via a water seal chamber in which liquid is received. The pressure between the vacuum source and the water seal chamber is measured by a pressure sensor, and the occurrence of air bubbles created in the water seal chamber is detected on the basis of fluctuations of this pressure.

Abstract: A speaking valve which is applied to a respiration opening of a tracheostomy tube comprises: a main body portion which has a passage portion communicating with the respiration opening; a balloon which makes a motion between an opened state for opening the passage portion of the main body portion and a closed state for closing the passage portion; a syringe which is provided away from the main body portion and accepts a pushing operation to a plunger by a patient; and a coupling tube which couples the syringe and the balloon with each other and makes the balloon in a shrink state transform to a bloat state by the operation to the syringe, so that the motion from the opened state to the closed state is made.
