Abstract
Embodiments are described that relate to flow rate measuring systems that may be used in cell expansion systems (CES) and in methods for controlling fluid input into systems such as a CES.
Claims20
A system comprising:
- a cell growth chamber;
- a flow rate measuring system comprising:
- a first weight measuring device adapted to weigh a container of fluid;
- a holding assembly adapted to connect the container of fluid to the weight measurement device;
- at least one processor, wherein the at least one processor is connected to the flow rate measuring system;
- and
- a pump connected to the at least one processor and adapted to move the fluid from the container into the cell growth chamber.
4 more elements
A flow rate measuring system comprising:
- a holding assembly;
- a first weight measuring device;
- a spacer attaching the holding assembly to the first weight measuring device;
- and
- a beam attached to the first weight measuring device and adapted to connect to a pole.
2 more elements
A method of controlling fluid input into a cell expansion system, the method comprising:
- receiving, by at least one processor, an initial weight of a fluid for pumping into a cell expansion system;
- receiving, by the at least one processor, a first pump flow rate;
- starting a pump at the first pump flow rate;
- receiving, by the at least one processor, a current weight of the fluid;
- calculating, by the at least one processor, an actual pump flow rate;
- determining, by the at least one processor, that the actual flow pump rate differs from the first pump flow rate by more than a predetermined amount;
- and
- adjusting the pump flow rate based on the determining.
