摘要： A pump mechanism using a drive motor having an external rotor. In one case, cams are mounted on the external surface of the rotor. Cam followers or peristaltic fingers engage the cams and move linearly in response to the rotational cam motion. The cam surfaces are rotated from adjacent cam surfaces to achieve a peristaltic effect through the peristaltic fingers sequentially pressing against the fluid tubing. In another case, the external surface of the rotor is threaded and elongated. A nut is mounted on the rotor and confined to travel in only a linear direction. A coupling arm is connected between the nut and a syringe plunger to force the plunger into the syringe barrel and thereby move the fluid.

摘要： The clamp for flexible tubing may be used in conjunction with an infusion pump instrument or separately. The clamp includes a pair of elongated clamping members pivotally hinged together and biased to clamp a segment of flexible tubing received between the clamping members. A latch is also preferably provided for allowing the clamping members to be releasably latched apart. The latch, and the elongated clamping members are arranged in a manner such that when the clamp has a segment of flexible tubing received between the clamping members and the clamp and tubing are set between the housing and door of an infusion pump, closing the door causes the clamp to release to an open position allowing fluid flow, and opening the door causes the clamp to automatically move to a closed position, clamping the tubing so as to prevent fluid flow.

摘要： A system and method for generating a gas-supersaturated fluid and delivering the fluid at high delivery pressures to thereby prevent bubble nucleation is disclosed. The system comprises a housing for containing a removable fluid assembly for housing a fluid to be gas-supersaturated and a drive assembly for delivering the fluid to a delivery site. The housing assembly comprises a cylinder and a piston which may be advanced along the inner surface of the cylinder to pressurize and to deliver the fluid. To generate a gas-supersaturated fluid, the housing assembly is removed from the system housing, filled with a fluid, and gas is introduced at or slightly above the desired gas partial pressure into the cylinder. To deliver the gas-supersaturated fluid, the fluid assembly is returned to the system housing and the drive assembly advances the piston to increase the hydrostatic pressure to the desired delivery pressure and, after opening a valve, to deliver the gas-supersaturated fluid at the desired high delivery pressure to a delivery site.

摘要： A fluid shut off valve for use in a parenteral fluid administration set includes a disk floating in a fluid chamber that shuts off fluid flow when the fluid in the chamber decreases below a certain level. The chamber includes a valve stem at its lower end that has both a valve seat and an alignment member with an alignment surface on the top end thereof for guiding the disk into proper seating on the valve seat. The valve seat and floating disk have complementary engagement surfaces for also guiding the disk into proper seating on the valve seat. In one embodiment, the alignment member includes fins located both on the valve stem and on the inside wall of the chamber. Because of the configuration of the alignment member, dislodgement of the disk from the valve seat is made easier.

摘要： An apparatus and method for detecting pressure and occlusion in a fluid line is for use with a fluid line being operated upon by a positive displacement, peristaltic pump having several cam follower fingers pressing against the fluid line fluid through the line peristaltically. A sensor follower finger is mounted to the cam shaft of the pump among the other peristaltic fingers in order to cyclicly press against the fluid line and displace the fluid line by a predetermined amount as the cam shaft rotates. The sensor follower finger includes a strain gauge mounted on the sensor finger to generate a signal indicating the degree of force being applied by the sensor finger against the tubing, and a signal processor which receives this force signal and determines the pressure within the fluid line based upon the signal. The signal processor determines the existence of an occlusion based on the signal and provides an alarm if an occlusion is determined.

摘要： The negative pressure monitor is intended for use in combination with an IV administration set, for monitoring venous, arterial and other physiological pressure signals. The system provides a coupling mechanism with a sealed vacuum chamber between a fluid chamber in communication with the fluid in line, and the pressure transducer. The vacuum in the coupling mechanism serves not only to communicate pressure changes within the fluid chamber to the pressure transducer, but also functions to maintain the fluid chamber in pressure communication with the pressure transducer.
