A sensor emits a magnetic field and a detector causes another magnetic field to be generated. The interaction of the two magnetic fields causes a pulse to be generated. Based on the timing of the generated pulse, the apparatus or method determines the absolute position of the support coupled to the container and adjusts the height of the support. Circuitry is also provided to prevent changes in height of the support by preventing supply of drive currents and by applying a hold current or by generating an electro motive force.Type: ApplicationFiled: December 13, 2002Publication date: June 17, 2004Inventors: Argelio M.

Publication number: 20040097886Abstract: An in-line drug delivery pack that connects in-line with an intravenous (IV) line and allows for the mixing of diluent with a drug reagent to be delivered to the patient. An internal drug bed bypass mechanism is tailored to apportion diluent flow between the bypass and the drug bed. The apportionment is selected to achieve a solution concentration suitable for IV administration as the dried reagent is dissolved. Thus, both dissolution and precisely tailored dilution are performed in the same simple device.Type: ApplicationFiled: November 12, 2003Publication date: May 20, 2004Inventor: Michael A. Taylor

Patent number: 6712786Abstract: A single-use preassembled medical device for administering at least two drugs in preset proportions to patients, comprising at least one pair of independent injectors and at least one pair of piercing couplings for corresponding bottles containing the drugs which are reciprocally connected by corresponding tubes which lead into a single tube for infusion to a patient; at least one of the piercing couplings is of a conventional type and the second one is of a dedicated type, forming a conveniently provided small cup-shaped receptacle for the precision insertion of the neck of a bottle of a preset drug whose dimensions are likewise correspondingly smaller than those of a normal bottle.Type: GrantFiled: June 8, 2001Date of Patent: March 30, 2004Assignee: Sidam di Azzolini Graziano E C. S.a.s.Inventor: Graziano Azzolini

Publication number: 20040059287Abstract: A method enables fluids to be administered intravenously to a patient using an intravenous (IV) fluid supply system. The method comprises coupling a first fluid path in flow communication to a first fluid reservoir, coupling an inlet of a drip chamber in flow communication to the first fluid path, coupling an outlet of the drip chamber in flow communication to a patient supply path, and coupling a bypass fluid path in flow communication to the first fluid path. The method also comprises directing fluid flow from the first fluid reservoir to the patient through the first fluid path and the drip chamber, and directing fluid flow from the first fluid reservoir to the patient through the bypass fluid path such that the drip chamber is bypassed.Type: ApplicationFiled: September 24, 2002Publication date: March 25, 2004Inventors: Richard Donald Vest, Deborah Susan Vest

Publication number: 20040054320Abstract: A drug delivery device that utilizes a fluid subsystem with a switching device to deliver multiple drugs to an animal without causing contamination. The fluid subsystem can further comprise disposable syringes, fluid reservoirs, disposable tubing and a catheter. In the embodiments that utilize multiple disposable syringes, the drug delivery device allows a user to deliver multiple drugs to an animal through a catheter without contaminating the switching devices that control the flow of fluid. The drug delivery device can further utilize a controller to control the switching devices and a controller and syringe pumps to control the operation of the syringes.Type: ApplicationFiled: July 2, 2003Publication date: March 18, 2004Applicant: Bioanalytical Systems, Inc.Inventors: Candice B. Kissinger, James M. Hampsch, Joseph A. Bougher

Publication number: 20040030284Abstract: A system is used for identifying IV administration set components, wherein the IV set includes an IV solution container, a drip chamber having a hollow spike for introduction into the container, and an IV line for delivering the IV solution to a patient. The system includes a first identification element that is removably attached to the drip chamber for subsequent attachment to the container; a second identification element permanently affixed to the drip chamber; and a third identification element that is either permanently or removable attached to a Y-site or port in the IV line. In a preferred embodiment, the first identification element is a strip or patch that is adhesively attached to the drip chamber in a manner that will allow it to be removed therefrom for subsequent attachment to the container. The second identification element is a marker, preferably a strip or a patch, that is permanently affixed to the drip chamber.Type: ApplicationFiled: July 29, 2003Publication date: February 12, 2004Inventor: Timothy Y. Kraushaar

Patent number: 6685670Abstract: An apparatus and method for preventing free flow through an infusion set utilizes an occluder disposed within the infusion set to selectively prevent flow therethrough. The occluder may be responsive to a pressure differential within the infusion set or may respond to compression of the infusion set. When a pair of occluders are used in sequence, an in-line pump may be formed.Type: GrantFiled: April 12, 2002Date of Patent: February 3, 2004Assignee: Zevex, Inc.Inventors: Scott Miles, Kent F.
