METHODS, DEVICES, AND SYSTEMS FOR MOVING A FLUID ALONG A FLUID PATH FOR TREATMENT

摘要

The devices and systems are medical fluid treatment therapies. The device and systems are configured and capable of operating based on small volumes of fluids. The devices and systems include a pump configured for small volume of a fluid. The pump may include a first conduit configured for inflow of the fluid; a second conduit configured for outflow of the fluid; a fluid chamber configured to move the fluid through the pump; a diaphragm configured to force the fluid through the fluid chamber by indirectly exerting force on the fluid chamber; and a connector configured to removably attach the pump to a motor.

1. A method for moving a fluid along a fluid path, comprising:
flowing a fluid into a fluid chamber disposed in a first section of a fluid pump, the fluid chamber including a lower surface; driving an actuator to move a diaphragm toward the fluid chamber into the first section of the fluid pump to transfer a force through a cavity filled with an incompressible fluid or material to the fluid chamber; and expelling the fluid from the fluid chamber when at least the lower surface is deflected by the force.
