Abstract
The present disclosure relates to a system for extracorporeal blood circulation, including an oxygenator which includes a heat exchanger configured for warming or cooling blood in extracorporeal blood circulation of a patient, and a heater/cooler configured for exchanging a quantity of heat with the heat exchanger, wherein the heater/cooler includes an thermoelectric heater/cooler and wherein the heater/cooler (14) is connected to the heat exchanger (11) by a thermal connecting element (15).
Claims10
A system for extracorporeal blood circulation, comprising:
- an oxygenator which includes a heat exchanger configured for warming or cooling blood in the extracorporeal blood circulation of a patient, and
- a heater/cooler configured for exchanging a heat quantity with the heat exchanger,
- wherein the heater/cooler comprises a cooler including a plurality of Peltier elements and a separate heater, wherein the separate heater consists of at least one heating coil and does not include any Peltier elements, wherein all Peltier elements are exclusively involved with a cooling function, and
- wherein the heater/cooler is connected to the heat exchanger by a thermal connecting element.
A system for extracorporeal blood circulation, comprising:
- an oxygenator which includes a heat exchanger configured for warming or cooling blood in the extracorporeal blood circulation of a patient,
- a heater/cooler configured for exchanging a heat quantity with the heat exchanger, and
- a reservoir configured for storing a heat exchanging medium and connected to the heat exchanger,
- wherein the heater/cooler comprises a cooler disposed outside the reservoir and including a plurality of Peltier elements and a separate heater, wherein the separate heater consists of at least one heating coil and does not include any Peltier elements, wherein all Peltier elements are exclusively involved with a cooling function, and
- the heater/cooler is connected to the reservoir and configured to heat or cool the heat exchanging medium, stored in the reservoir and circulated through the heat exchanger.
A system for extracorporeal blood circulation, comprising:
- an oxygenator which includes a heat exchanger configured for warming or cooling blood in the extracorporeal blood circulation of a patient,
- a heater/cooler configured for exchanging a heat quantity with the heat exchanger, wherein the heater/cooler comprises a cooler including a plurality of Peltier elements and a separate heater, wherein the separate heater consists of at least one heating coil and does not include any Peltier elements, wherein all Peltier elements are exclusively involved with a cooling function, and
- a thermal connecting element connected between the thermoelectric heater/cooler and the heat exchanger, the thermal connecting element comprising a thermally conductive metal for transferring heat between the thermoelectric heater/cooler and the heat exchanger such that no liquid heat exchanging medium passes between the thermodynamic heater/cooler and the heat exchanger.
