Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] Such as Figure 1-8 The control system for the cultivation parameters of the bioreactor shown includes a main control unit 1, a sub-control unit 2, a tray 7 and a cell culture bag 8;

[0042] The main control unit 1 is used to receive the parameter information set by the user and control each sub-control unit 2 to perform corresponding operations according to the parameter information; the sub-control unit 2 includes a temperature control unit 3, a liquid control unit 4, a gas control unit 5 and a shaking control unit 6 ;

[0043] The temperature control unit 3 controls the heating device 3.4 to heat the cell culture bag 8 containing the cell mixture according to the parameter information, and adjusts the heating state of the heating device 3.4 according to the temperature data collected and fed back by the temperature probe i...

Abstract

The invention discloses a control system and method for culture parameters of a bioreactor. The system comprises a main control unit, sub-control units, a tray and a cell culture bag, wherein the maincontrol unit is used for receiving parameter information set by a user and controlling each sub-control unit to perform corresponding operations according to the parameter information; the sub-control units comprise a temperature control unit, a liquid control unit, a gas control unit and a shaking control unit; the temperature control unit, the liquid control unit, the gas control unit and the shaking control unit are controlled by one main control unit. The bioreactor is different from the existing disposable bioreactor in system architecture and structural form, and each sub-control unit belongs to closed loop control, so that the whole system has high control precision, good control stability and quick system response.

Description

technical field [0001] The invention relates to the field of biomedical technology, in particular to a control system and method for culturing parameters of a bioreactor. Background technique [0002] Disposable bioreactors can be divided into wave-type, stirring-type and track-type bioreactors according to different movement modes and platforms. Different types of disposable bioreactors have different system architectures, structural forms, and control methods. For example, in the control of temperature parameters on a stirred disposable bioreactor, the outer layer of the tank is covered with a heating jacket, and constant temperature water is circulated inside the heating jacket. During the circulation process, a heat exchanger is used to heat or cool the jacket water. The temperature of the tank is indirectly controlled by directly controlling the temperature of the jacket circulating water, which constitutes a principle similar to a constant temperature water bath. The t...
