Abstract: A heater-cooler apparatus of an extracorporeal perfusion system comprises at least one fluid circuit 102, 104 providing a supply of a heat transfer fluid to the perfusion system, a cold storage unit 266, and a refrigeration unit 250 for charging the cold storage unit 266. The cold storage unit 266 comprises a chamber 312 containing a liquid that freezes at a temperature above that to which the heat transfer fluid is cooled by the refrigeration unit 250, and a passage through which the heat transfer fluid is conveyed, the passage extending through the chamber 312. This allows a more effective cold storage unit to be provided.

Abstract: A baby bouncer with assistance having a base, a seat to receive a baby, a joint connecting the seat with the base and configured to support the seat above the base, and an actuator connected between the base and the seat. The joint permits reciprocating motion of the seat relative to the base. The actuator can impart a driving force on the seat.

Abstract: A method of controlling thermal transfer in a perfusion system heat exchanger of an extracorporeal fluid treatment device for conditioning an extracorporeal patient fluid for administration to a patient comprises a step of providing a perfusion system heat exchanger, wherein the perfusion system heat exchanger comprises a first fluid passage for a liquid heat transfer medium and a second fluid passage for the extracorporeal patient fluid to be temperature-controlled via exchange of thermal energy with the heat transfer medium, and a step of providing the heat transfer medium through the first fluid passage. The heat transfer medium comprises a component with anti-microbial properties, such as glycol. The provision of antimicrobial fluid reduces the risk of microbe contamination of the extracorporeal fluid, and hence the risk of clinical complications.

Abstract: An exhaust gas flow control system for an oxygenator of an extracorporeal ventilation system connected to an oxygenation gas supply line and to an exhaust line for removal of exhaust gas comprises a flow control path, a pressure control path, an exhaust flow regulator responsive to the controller, and an exhaust gas pressure regulator responsive to a controller configured to maintain a pre-determined pressure level in the exhaust line. This provides a better degree of control over the pressure across the oxygenator from oxygenation gas inlet to exhaust.
