A pulsatile fluid pump system includes a pump-valving assembly including a chamber and a diaphragm assembly coupled to the chamber and including a flexible diaphragm. The diaphragm assembly and the pump-valving assembly are configured as an integral pump assembly. The system further includes a linear motor having a magnet and a coil, the magnet moving in relation to the coil, the coil having an electrical input. The system also includes a control housing rigidly coupled to the linear motor and a controller system having an electrical output coupled to the electrical input of the coil, the controller system defining an electrical waveform at the electrical output to cause desired operation of the diaphragm. The integral pump assembly is configured to be removably coupled to the control housing, and the diaphragm assembly of the integral pump assembly is configured to be removably coupled to the linear motor.

Pulsatile fluid pump system

A pulsatile fluid pump apparatus includes an integral pump assembly employing a flexible diaphragm in a diaphragm assembly; a pulsatile fluid pump system including a control housing, for removably receiving the integral pump assembly, the control housing and the integral pump assembly being configured for operation, in a first mode, so that the pulsatile fluid pump system reciprocally actuates the diaphragm assembly to cause pumping automatically; and a manual driver assembly, wherein the integral pump assembly is configured, in a second mode, in the absence of actuation of the diaphragm assembly by the pulsatile fluid pump system, to removably receive the manual driver assembly to support manual actuation and operation of the diaphragm assembly.

A fluid control system for delivery of a liquid includes a pneumatic drive that incorporates a linear actuator to effect known volume changes in a gas reservoir. The gas reservoir is in fluid communication with a gas-side reservoir that is separated from a fluid-side reservoir by a flexible membrane. Movement of the linear actuator effects positive or negative volume differences on the gas in the gas-side reservoir, resulting in a decrease or increase in pressure of the gas that is transmitted to the fluid-side reservoir to draw fluid, primarily liquid, in from a source or deliver liquid out to a sink. In another aspect, a mechanism is provided for the detection and elimination of air bubbles in the fluid path.

An infusion pump and method are provided which control flow rates with variable fluid pressure and variable series flow resistance.

Flow control system and method with variable pressure and variable resistance

A device for control of fluid flow with closed loop quasi static adjustment of in-line pressure-based resistance. The disclosed device and methods of using the device provide for the ability to control a flow rate with a highly portable device; the ability for an operator to safely use the device with minimal training; the ability to automatically switch between a primary and secondary fluid; the ability to maintain a flow rate through a tubing set even when the control device is removed; and the ability to measure fluids introduced with a manual bolus injection.

Automated fluid flow control system

A slide cartridge for use with a chemical analyzer includes an upper ring and a lower ring secured together but rotatable with respect to each other. The upper and lower rings define a plurality of reaction chambers between them, which receive dry analyte test slides. A gear track formed in the underside of the lower ring engages a pinion gear attached to a stepping motor of the chemical analyzer in order to rotate the slide cartridge. The slide cartridge is rotated under a sample fluid metering device, which deposits a sample fluid on the test slides through a plurality of spotter ports formed in the upper ring, and above a reflectometer, which performs a colorimetric measurement on the spotted test slides through viewing windows formed in the lower ring of the slide cartridge. A chemical analyzer with which the slide cartridge may be used includes a reflectometer, a sample fluid metering device and a stepping motor for rotating the slide cartridge.
