Maquet HCU 40

Maquet HCU 40 Heater/Cooler System

The Maquet HCU 40 Heater/Cooler System from the Getinge Group is designed for precise thermal regulation during cardiovascular interventions. It efficiently warms or cools the water that flows through a blood oxygenator/heat exchanger or a warming/cooling blanket, ensuring that patient blood temperature is maintained or adjusted as needed during cardiopulmonary bypass procedures. The system operates independently of the water supply in the operating room and features dual water circuits—one dedicated to the heat exchanger and one to the warming/cooling blanket—allowing for independent temperature control. With an operating temperature range from 33.8°F to 104.9°F (1°C to 40.5°C), fast temperature adjustment via an automatically controlled mixing valve, and a user-friendly touchscreen interface, the HCU 40 delivers both performance and reliability.

Key Features

• Precise Temperature Regulation:

  • Independently control water temperatures for the heat exchanger and the warming/cooling blanket.
  • Temperature range from 33.8°F to 104.9°F (1°C to 40.5°C) with high accuracy (±0.3°C).

• Dual Water Circuits:

  • Two separate water circuits allow simultaneous management of cardioplegia and patient warming/cooling.
  • Integrated automatically controlled mixing valve and split tank enable rapid temperature adjustments.

• Efficient Thermal Performance:

  • High water flow rates at low pressures improve heat exchange efficiency.
  • Great heat capacity reduces patient rewarming time.
  • Ice-building system helps further reduce patient cooling times.

• User-Friendly Operation:

  • Intuitive touchscreen graphical user interface simplifies programming and monitoring.
  • Fast priming and automatic de-airing capabilities ensure quick setup and safe operation.
  • Compact design with independent flow controls permits remote placement of the unit outside the operating room.
