A disposable infusion apparatus includes proximal, distal and intermediate segments of IV tubing connected via couplings. The intermediate segment has a length sufficient for operative engagement with a pumping member of a peristaltic pump throughout a pumping stroke thereof. The intermediate segment further has a maximum Durometer of seventy-five on the Shore A scale. The pumping member includes a plurality of fingers mounted in side-by-side substantially parallel relationship for individual reciprocation. Motor driven cams individually reciprocate respective ones of the fingers in a predetermined timed sequence so that when the linearly disposed intermediate segment is squeezed by the fingers, intravenous fluid in the tubing will be pumped therethrough. The disposable apparatus further includes a door connected to opposite ends of the intermediate segment and which is releaseably loadable in a case to place the intermediate segment into operative engagement with the pumping member.

Disposable infusion apparatus and peristaltic pump for use therewith

A luminometer for analyzing genetic or non-genetic maaterial comprises an optical chamber for receiving and holding a vial of the sample material in a dark environment. A pumping system mounted in the luminometer pumps reagents into the vial to cause the sample material to luminesce, and a sensor is positioned in the dark environment relative to the vial to detect the luminescence. Instantaneous intensities of the luminescence are sequentially sampled at set intervals of time during a preselected time period and summed by a microprocessor to generate a signal that is descriptive of the constituents of the sample.

A programmable infusion system includes a disposable IV tubing apparatus for conveying intravenous fluid from a source to a patient. A compact, portable case has a receptacle for removably receiving a segment of the disposable apparatus. A peristaltic pump is mounted in the case for engaging the segment of the disposable apparatus and pumping intravenous fluid therethrough. A motor is mounted in the case and is connected for driving the pump upon energization thereof. A bar code reader is mounted in an edge portion of the case for sensing a bar code label attached to the source of intravenous fluid, such as a bag. The bar code label represents the prescribed fluid delivery parameters. These are read and displayed in alphanumeric form by the system when the edge portion of the case containing the bar code reader is passed over the label. A micro-controller mounted in the case energizes the motor so that the peristaltic pump conveys the fluid through the disposable apparatus in accordance with the delivery rate parameters.
