Abstract: A liquid delivery device which controls the flow of liquid from a liquid reservoir includes a resilient tubing having a wall with a substantially cylindrical cross-section defining a flow lumen. The flow lumen is in fluid communication with the reservoir. A compression member selectively compresses a lengthwise segment of the cylindrical wall to collapse the flow lumen and releases the lengthwise segment to open the flow lumen. An elastomeric sleeve envelopes greater than half an outer diameter of the cylindrical cross-section of the resilient tubing along at least a portion of the lengthwise segment of the cylindrical wall. The elastomeric sleeve biases the lengthwise segment of the resilient tube to restore it to its substantially cylindrical cross-section when the compression member releases the lengthwise segment.

Abstract: A method of installing an anti-siphon flow restricter into a gas flow lumen of a nebulizer includes providing an anti-siphon flow restricter having a side wall conforming to a cross section of the gas flow lumen, first and second ends at opposite ends of the side wall and an elastomeric diaphragm closing the first end of the side wall. The anti-siphon flow restricter is axially inserted into the gas flow lumen with the diaphragm leading. The diaphragm is slit and allowed to self-bias closed.

Abstract: A remotely programmable infusion system for administering liquid to a patient includes an infusion pump unit having a pump for infusing liquids operated by means of a control including a programmed processing unit and a memory chip. The processing unit operates in accordance with delivery program data stored in the memory circuit for executing an infusion delivery sequence. An output circuit is operatively disposed between the processing unit and the pump unit to control operation of the pump unit in accordance with the infusion delivery sequence. A wireless data communication circuit is operatively connected to the control for transmitting and receiving data.
