Abstract: A pressure sensing assembly for an infusion pump, including: a tubing guide arranged to receive tubing; a displaceable load assembly at least partially disposed within the tubing guide and with a first surface facing in a first direction; a load cell facing the load assembly in the first direction; and a displacement assembly engaged with the tubing guide, facing the first surface in a second direction, opposite the first direction, and exerting a first force on the load assembly in the first direction. The load cell is arranged to detect a second force, greater than the first force, acting on the load cell in the second direction.

Abstract: An infusion pump, including: a specially programmed microprocessor; a drip chamber for connection to a source of fluid and to an output tubing; a pumping section including a plurality of fingers and a first actuator, controllable using the microprocessor, for sequentially displacing the plurality of finger to compress a first portion of the output tubing to displace fluid from the drip chamber through the output tubing; an inlet valve disposed between the drip chamber and the pumping section and arranged to compress the output tubing to restrict or block flow through the output tubing; and a second actuator, controllable using the microprocessor, for opening or closing the inlet valve independent of the displacement of the plurality of fingers; or for operating the inlet valve to control a rate of flow of fluid from the drip chamber to the portion of the output tubing.

Abstract: A system for managing an infusion therapy, including: a server in communication with a central server; and an infusion pump in wireless communication with the server and for: uploading respective label data from respective labels for at least one medication, the respective label data including respective label pump programming data for infusion of the at least one medication by the pump; wirelessly transmitting the uploaded label data to the server; and wirelessly transmitting pump data identifying the pump to the server. The server is for transmitting the pump data and the respective label data to the server; and receiving, from the central server and in response to receipt of the pump data and the respective label data by the central server, second pump programming data regarding a second medication. The server is for comparing the first pump programming data with the second pump programming data.

Abstract: An infusion pump, including: a microprocessor; a drip chamber; a drip tube with an end in the drip chamber; and an illumination system: with a light source for transmitting light through the drip chamber to a drop of fluid suspended from the drip tube; and for controlling illumination properties of the light transmitted to the drop. The pump includes an optical system for: receiving light transmitted through the drop; and transmitting, to the microprocessor, data regarding the received light. The microprocessor: generates, using the data, an image of the drop; locates, using the image, an outer edge of the drop to define a boundary of the drop; integrates an area enclosed by the boundary; and calculates a volume of revolution for the drop with respect to an axis for the drop that intersects the end of the drip tube, assuming symmetry of the drop with respect to the axis.

Abstract: An infusion pump including an interface unit for receiving first data for a first infusion regimen for a medication, the first regimen including a first unit of measure in which the first regimen is executed and after receipt of the first data, second data for a second infusion regimen for the medication, the second regimen including a second unit of measure in which the second regimen is executed. The pump also includes a processor for comparing the first and second units of measure. In one embodiment, the pump includes a graphical user interface, and the processor identifies a difference between the first and second units of measure; generates, using the processor, a warning message; and displays the message on the graphical user interface. In another embodiment, the processor holds in abeyance initiation of the second infusion regimen in response to identifying the difference between the units of measure.
