Abstract: The present invention provides a method and system for the reference, archival and retrieval of symbolically linked information despite idiosyncratic symbol (120a1, 120c1, 120a2, 120c2, 120a3, 120b3, 120c3) usage. A master symbol (115c) database stores a plurality of master (115c) symbols, wherein each master (115c) symbol is formatted according to a predetermined structure. Each master symbol (115c) in the master symbol (115c) database is linked to a parent identifier (110) that identifies a unique object (130). Users may archive or retrieve symbolically linked information in an information database by providing an input symbol. The input symbol is normalized and the master symbol (115c) database is searched to find a matching master symbol (115c).  The parent identifier (110) linked to the matching master symbol (115c) is then used to retrieve or archive information in the information database.

Title: Disposable infusion cassette with low air bubble retention and improved valves
Inventor: GJATA JOHN D
IPC: A61M1/00
Filed: 2002-03-11
Granted: 2010-01-19
Abstract: A disposable cassette for use with a medical infusion pump. An elastomeric membrane is captured between a facing member and a base of the cassette and is displaced into a pumping chamber. The elastomeric membrane includes a generally T-shaped lip, and corresponding grooves are provided on the facing member and base. As the cassette is assembled, an interference fit between t he lip and the grooves causes the membrane to stretch taut and to be securely anchored, eliminating a break-in period when the cassette is initially used. "Lobes" of increased thickness provided on the undersurface of a portion of the elastomeric membrane overlying the pumping chamber reduce the residual volume of the pumping chamber, thereby reducing the volume of air retained within the chamber and increasing the accuracy of the cassette. The lobes al so sweep air bubbles from the sides of the pumping chamber during operation, further reducing air bubbles retained in the pumping chamber. A distal tube support retains a distal fluid line between air or pressure sensors included on a pump drive mechanism, thus reducing the likelihood of sensing errors. Inlet and outlet valve flaps and corresponding seating surfaces included in the base are configured to provide quieter operation, further reduce the residual volume of thepumping chamber, increase fluid velocity through the outlet valve to sweep air bubbles from the pumping chamber, and protect against a "blown" inlet valve.
