DETAILED DESCRIPTION OF THE PRESENT INVENTION

To teach the technical solutions of the present invention, some conventional aspects have been simplified or omitted. It should be understood by those skilled in the art that variants or substitutions derived from these embodiments shall fall within the scope of the present invention. It should be understood by those skilled in the art that the following features can be combined in various ways to form various variants of the present invention. Therefore, the present invention is not limited to the following optional embodiments, but is only defined by the appended claims and equivalents thereof.

EXAMPLE 1

[0026] FIG. 1 schematically shows a structure of an integrated system of cell culture and operation according to an embodiment of the present invention. As shown in FIG. 1, the integrated system of cell culture and operation includes: a housing, a transport module, a plurality of heating modules, a filter, a regulation device, a sensor and a processor.

[0027] The housing is provided with a gas inlet, a gas outlet and a humidifying port. The housing has a double-layer structure consisting of an inner layer and an outer layer. An upper wall and a lower wall of the inner layer both are provided with through holes. A front side of the housing is provided with operating gloves.

[0028] The transport module, such as a fan, is arranged on the upper wall of the inner layer at a position where the through hole is provided or arranged at a lower side of the through hole to transport the gas in the inner layer to the regulation device so that the gas circulates in the inner layer and an interlayer.

[0029] The heating modules such as heating sheets are arranged in the interlayer, for example, on an inner wall of the outer layer and in a side, an upper portion and a lower portion of the interlayer. The heating module at a front side of the interlayer is transparent, which is convenient for observing the inner layer and improves the heating uniformity.

[0030] The filter is arranged on a lower portion of the transport module. A projection of the filter in a horizontal plane overlaps with a pattern formed by the surrounding inner wall of the inner layer in the horizontal plane.

[0031] The regulation device is in a state of storing or releasing the target gas according to different working parameters. The regulation device is arranged in the upper portion of the interlayer. Here, two regulation devices, including an oxygen molecular sieve and a carbon dioxide molecular sieve, are provided in this embodiment, so that gaseous molecules are adsorbed and desorbed using Pressure Swing Adsorption (PSA) to store or release the target gas.

[0032] The sensor is configured to detect contents of oxygen and carbon dioxide in the inner layer and send the detected contents to the processor.

[0033] The processor is configured to regulate the working states of the two regulation devices according to the detected contents. If the detected contents are less than a target value, the regulation devices are controlled to be in a state of releasing the target gas; if the detected contents are greater than the target value, the regulation devices are controlled to be in a state of storing the target gas.

[0034] This embodiment of the present invention further provides a working method of the integrated system of cell culture and operation, including the following steps.

[0035] (A1) The gas is transported by the transport module to flow downward in the inner layer.

[0036] (A2) The gas enters the interlayer through a through hole of the lower wall of the inner layer to flow in a lower portion, a side and an upper portion of the interlayer. The gas is then heated by the heating module.

[0037] Condensed water is not formed on an inner wall of the inner layer.

[0038] (A3) The gas enters the inner layer through a through hole on the upper wall of the inner layer.

[0039] A method for controlling the contents of target gases in the inner layer, includes the following steps.

[0040] (B1) Contents of target gases, including oxygen and carbon dioxide in the inner layer of the integrated system of cell culture and operation, are detected by a gas sensor. The detected contents are sent to the processor.

[0041] (B2) Working states of the regulation devices are controlled by the processor. If the contents of the target gases are to be reduced, proceed to step (B3). If the contents of the target gases are to be increased, proceed to step (B4). If no adjustment is required, proceed to step (B5).

[0042] (B3) The regulation devices are controlled to a state of storing the target gas by controlling the parameters of the regulation devices. The gas is transported by the transport module from the lower wall of the inner layer into the interlayer. The gas flows upward to an upper wall of the interlayer along a side wall of the interlayer. The target gases in the gas is stored by the regulating device to finally enter the inner layer from the upper wall of the inner layer. Proceed to step (B1).

[0043] (B4) The regulation devices are controlled to a state of releasing the target gas by controlling the parameters of the regulation devices. The gas is transported by the transport module from the lower wall of the inner layer into the interlayer. The gas flows upward flow upward to the upper wall of the interlayer along the side wall of the interlayer. The target gases stored by the regulation devices are released into the gas to finally enter the inner layer from the upper wall of the inner layer. Proceed to step (B1).

[0044] (B5) Ends.

[0045] In the above process, if the content of the target gas in the inner layer still cannot reach the target value within several cycles, external gas is injected into the housing through a gas inlet thereon. If the content of the target gas in the housing is always less than the target value, gas with the content of the target gas greater than the target value is injected to increase the content of the target gas in the housing. If the content of the target gas in the housing is always greater than the target value, gas with the content of the target gas less than the target value is injected to reduce the content of the target gas in the housing.

[0046] The present invention provides an integrated system of cell culture and operation which differs from Example 1. In this example:

[0047] 1. The regulation devices are arranged outside the housing. An input end and an output end of the regulation device is in communication with the sidewall of the interlayer of the double-layer housing, respectively.

[0048] 2. Additional transport module is provided to transport the gas in the interlayer to the regulation devices.
