Abstract
Methods of and devices for testing medical pumps via tracking induced bubble trajectories within a fluid flow conduit comprising a valve and methods of synchronized corrections of flow data estimates.
Claims16
A method comprising:
- moving, by a signal processing unit, a tracking point aligned with a first edge of a bubble moving in a first direction and present in a fluid flow in a conduit having a trackable area;
- determining, by the signal processing unit, when the tracking point reaches an optimal direction switch point, wherein the optimal direction switch point is one direction switch margin from the end of the trackable area;
- stopping the fluid flow when the tracking point reaches the determined optimal direction switch point;
- moving, by the signal processing unit, the tracking point a direction switch margin in the first direction, wherein the direction switch margin is based on at least one variable;
- aligning, by the signal processing unit, the tracking point with a second edge of the bubble, wherein the second edge of the bubble is an edge that is opposite of the first edge of the bubble;
- initiating the fluid flow in a second direction, wherein the second direction is a direction that is a reverse direction of the first direction;
- and
- moving, by the signal processing unit, the tracking point aligned with the second edge of the bubble moving in the second direction.
