Abstract

A system for receiving a disposable bag ( 44 ) has a receiving container ( 10 ) with a container interior for receiving the disposable bag ( 44 ) and a temperature-control hollow wall ( 20 ) that at least partially surrounds the container interior of the receiving container ( 10 ). A temperature-control unit controls the temperature of the container interior by will a temperature-control medium arranged in the temperature-control hollow wall ( 20 ) at a maximum pressure of about 1 bar.

First claim

The invention claimed is:

1. An apparatus ( 1 ) for controlling a temperature of a biological medium, comprising:
a receptacle ( 10 ) with a receptacle wall ( 16 ) defining a receptacle interior,
a disposable bioreactor bag ( 44 ) disposed in the receptacle interior and being configured to receive the biological medium therein, a shape of the disposable bioreactor bag ( 44 ) being defined by the receptacle wall ( 16 ) of the receptacle ( 10 ),
a hollow temperature control wall ( 20 ) that at least partially surrounds the receptacle interior of the receptacle ( 10 ), the hollow temperature control wall ( 20 ) having an interior that contains a temperature control medium, and
an adjusting means configured to adjust a pressure of the temperature control medium in the interior of the hollow temperature control wall ( 20 ) to a maximum pressure of about 1 bar,

wherein the hollow temperature control wall ( 20 ) holds the temperature control medium at the maximum pressure of about 1 bar, and wherein the temperature control medium controls the temperature in the disposable bioreactor bag ( 44 ) that is disposed in the receptacle interior.

2. The apparatus according to claim 1 , wherein the adjusting means holds the temperature control medium in the interior of the hollow temperature control wall ( 20 ) at a pressure of about 0.20 bar to about 0.45 bar.

3. The apparatus according to claim 1 , further comprising at least one flow guide element ( 21 ; 22 ) arranged in the hollow temperature control wall ( 20 ) for guiding the flow of the temperature control medium through the hollow temperature control wall ( 20 ).

4. The apparatus according to claim 3 , wherein the at least one flow guide element ( 22 ) is inclined so that the temperature control medium flows through the hollow temperature control wall ( 20 ) with a continuous, vertical direction component.

5. The apparatus according to claim 1 , further comprising a collecting chamber ( 23 ) with a ventilation outlet ( 24 ) and a temperature control medium outlet ( 28 ) that is separate from the ventilation outlet ( 24 ), the ventilation outlet ( 24 ) and the temperature control medium outlet ( 28 ) are arranged on an upper end of the hollow temperature control wall ( 20 ).

6. The apparatus according to claim 1 , wherein the hollow temperature control wall ( 20 ) completely surrounds at least a lower third of the receptacle interior.

7. The apparatus according to claim 1 , wherein the hollow temperature control wall ( 20 ) controls the temperature of, and/or surrounds, the receptacle interior to above a predetermined fill level ( 40 ) in the receptacle ( 10 ).

8. The apparatus according to claim 1 , further comprising a relief valve for adjusting and/or limiting the pressure of the temperature control medium in the hollow temperature control wall ( 20 ).

9. The apparatus according to claim 1 , further comprising an electric heater that exchanges heat with the temperature control medium.

10. The apparatus according to claim 1 , further comprising tubing that conveys the temperature control medium through an external heat exchanger.

11. The apparatus according to claim 1 , further comprising an insulation at least partially formed on a side of the hollow temperature control wall ( 20 ) facing away from the receptacle interior, the insulation insulating the hollow temperature control wall ( 20 ) from the outside.

12. The apparatus according to claim 11 , wherein the insulation is at least partially arranged in a hollow insulation wall ( 25 ) formed on the side of the hollow temperature control wall ( 20 ) facing away from the receptacle interior.

13. The apparatus according to claim 1 , wherein the receptacle ( 10 ) has an openable door ( 30 ) through which the disposable bag ( 44 ) can be inserted into the receptacle interior in a substantially horizontal plane.

14. The apparatus according to claim 13 , wherein the receptacle ( 10 ) is a substantially vertical cylinder, and the door ( 30 ) of the receptacle ( 10 ) is constructed over a cylindrical sector of about 80° to about 150°.
