Terumo Sarns TCM II Heater Cooler

Terumo Sarns TCM II Heater/Cooler System

The Terumo Sarns TCM II Heater/Cooler System is a state-of-the-art, computer-controlled device designed for precise temperature management during cardiopulmonary bypass procedures. Utilizing advanced technology, the TCM II achieves rapid and reliable cooling by melting ice, while its powerful heaters and high-efficiency mixing manifold quickly bring temperatures up. This system features dual independent channels for temperature-controlled water, ensuring both the oxygenator/heat exchanger and the cardioplegia circuits are managed optimally. With user-friendly digital controls via its main display or optional remote module, operators can accurately set temperatures from 0°C to 42°C in one-degree increments, with added safety features to protect vulnerable pediatric patients through maximum water-to-venous blood temperature gradient settings.

Key Features

• Precise Temperature Management:
  • Maintains water temperatures between 0°C and 42°C with an accuracy of ±1°C.
  • Independent control of two channels: one for the oxygenator/heat exchanger and one for cardioplegia.
• Efficient Cooling and Heating:
  • Achieves faster, more reliable cooling by melting ice, ensuring rapid reduction of blood temperature.
  • Powerful heaters and a high-efficiency mixing manifold enable quick temperature increases.
• User-Friendly Operation:
  • Digital control via a clear, simplified display panel that provides accurate temperature data.
  • Optional remote control module offers flexibility in operation.
• Advanced Safety Features:
  • Built-in alarms and failsafe mechanisms ensure that temperature settings remain within safe limits.
  • Maximum water-to-venous blood temperature gradient can be set to protect pediatric patients during rewarming.
• Automatic Air Removal:
  • Rapid priming and automatic de-airing capabilities reduce setup time and enhance safety.
• Versatile and Reliable:
  • The TCM II functions independently of the main water supply, ensuring reliable performance even in challenging operating room environments.
