Cell suspension rotating fluidic pump

A method for dispensing a fluid containing substantially uniformly distributed particulates entrained therein, comprising the steps of:

• (a) providing a container having a longitudinal axis, the container including a volume of fluid in which is entrained a plurality of particulates;
• (b) rotating the container in which the fluid is disposed about its longitudinal axis using a first prime mover and a rate of rotation that results in the particulates in the fluid tracing a substantially circular pathway;
• and
• (c) dispensing the fluid independently of rotating the container using a second prime mover to manipulate a member introduced into the container to displace the fluid, such that dispensing occurs without requiring the container to be rotating.

A method for dispensing a fluid containing substantially uniformly distributed particulates entrained therein, comprising the steps of:

• (a) providing a container having a longitudinal axis, the container including a volume of fluid in which is entrained a plurality of particles, the container including a member configured to dispense fluid from the container when the member is manipulated;
• (b) rotating the container in which the fluid is disposed about its longitudinal axis before dispensing the fluid in the container using a first prime mover, such that the particulates become substantially uniformly distributed within the fluid in the container;
• (c) halting the rotation of the container;
• (d) dispensing the fluid when the container is not rotating using a second prime mover to manipulate the member to displace the fluid;
• and
• (e) repeating steps (b), (c), and (d).

A method for dispensing a fluid containing substantially uniformly distributed particulates entrained therein with reduced pulsatility, comprising the steps of:

• (a) providing a container having a longitudinal axis, the container including a volume of fluid in which is entrained a plurality of particles, the container including a member configured to dispense fluid from the container when the member is manipulated;
• (b) rotating the container in which the fluid is disposed about its longitudinal axis before dispensing the fluid in the container, such that the particulates become substantially uniformly distributed within the fluid in the container, using a first prime mover whose frequency modulation and phase characteristics are matched to a rate at which the container is rotated, to reduce a pulsatility induced in the fluid;
• (c) halting the rotation of the container;
• (d) dispensing the fluid when the container is not rotating;
• and
• (e) repeating steps (b), (c), and (d).
