Pump tester
Methods and devices for testing medical pumps via tracking the travel of at least one of: the leading edge and the trailing edge of induced single or multiple bubble trajectories within a light-transmissive fluid flow conduit by a photo-detector output of a first photo-detector disposed on a controlled, translatable carriage and methods of synchronized corrections of fluid flow data estimates.
1. A method of measuring fluid flow within a light-transmissive conduit comprising:
inserting, by a bubble pump, a first bubble into the fluid flow; and
tracking, by a signal processor unit configured to send at least one signal to a motor having a linkage configured to translate a controlled, translatable carriage, the travel of at least one of: the leading edge of the inserted first bubble and the trailing edge of the inserted first bubble, the tracking based on received emission levels of a photo-detector output by a first photo-detector disposed on the controlled, translatable carriage, wherein the translatable carriage is configured to move in a translational motion relative to the fluid flow.
2. The method of claim 1 wherein the signal processor unit comprises a central processing unit and addressable memory.
3. The method of claim 1 further comprising inserting, by the bubble pump, a second bubble into the fluid flow; and
tracking, by the signal processor unit configured to send at least one signal to the motor having the linkage configured to translate the controlled, translatable carriage, the travel of at least one of: the leading edge of the inserted second bubble and the trailing edge of the inserted second bubble, the tracking based on at least one of: received emission levels of the photo-detector output by the first photo-detector disposed on the controlled, translatable carriage and received emission levels of a second photo-detector output by a second photo detector disposed on the controlled, translatable carriage.
