A controller is configured to control the infusion subsystem and is responsive to the urine output measurement subsystem. The controller includes a balancing function which controls the infusion subsystem to administer fluid infused into the patient to balance the urine output with the fluid infusion. The controller also includes a taper down function which controls the infusion subsystem to administer fluid infused into the patient at a rate less than the rate of urine output by the patient.09-11-2008
20090043250Microneedle with membrane - Membrane containing microneedles, microneedle arrays, and needles, and systems and methods relating to same are disclosed.02-12-2009
20100286599CASSETTE FOR USE IN A MEDICATION DELIVERY FLOW SENSOR ASSEMBLY AND METHOD OF MAKING THE SAME - A disposable assembly for use with a sensor assembly comprises a body, a flow restricting element, and a fluid pressure membrane. The body has a lid portion and a base portion. The body defines a fluid flow passage that forms an inlet and an outlet. The flow restricting element is positioned in the fluid flow passage between the inlet and the outlet. The membrane is located between the lid and base portions along the fluid flow passage. A reinforcing structure, such as a ring or a rigid disk, is positioned between the fluid pressure membrane and the lid portion to provide increased resistance to pressure in the fluid flow passage. The ring or disk can be a separate component or formed on the membrane. The membrane thickness adjacent to sensor access openings in the lid portion can be increased for pressure resistance, too.11-11-2010
20120283630Flow Control Line Management Apparatus - A line management apparatus for managing multiple IV lines connected in a Y fitting or multi-way fitting provides for flow sensing and for electronic control of flow in the multiple lines. The line management apparatus may be used independently as a precise gravity feed IV system or may provide for use in combination with an infusion pump to ensure proper delivery of multiple solutions without blending of the two.11-08-2012
20130158472Subcutaneous Controlled Delivery System For The Topical Administration Of Drugs, Biological Agents Or Therapeutic Agents To Targeted Areas Within The Body - The present invention is directed to a subcutaneous controlled delivery device that provides for a refillable reservoir port, a release mechanism and tubing that operably connects the reservoir port to the release mechanism. Such a device is capable of being implanted under the dermis of the skin and allows for the controlled release of drugs, biological agents or therapeutic agents to a target site of interest in the body for treatment.06-20-2013
20110313350DRUG DELIVERY SYSTEM - Various embodiments of a “smart” drug delivery system are provided which includes an add-on module and a reusable or disposable drug pen. Upon attachment to the pen, the add-on module may: determine dosage selected, injection of selected dosage, duration of injection, time of injection, whether the pen has been primed or shaken to thoroughly mix up insulin mixtures, transmit information relating to insulin dosage and injection to a data management unit, provide reminders, error warning or messages on improper usage or reusage of needles, track amount of drug remaining on board the pen or duration of usage of pen with respect to expiry of the drug on board, or provide an audible alarm for locating misplaced pen and module.12-22-2011
20110313349MEDICAL MODULE FOR DRUG DELIVERY PEN - Various embodiments of a medical module are provided which includes a primary module housing, a secondary module housing, a dosage sensor, a power source, and a microcontroller. The module is configured to be attached to a disposable drug delivery pen or a reusable drug delivery pen so that the module may: determine dosage selected, injection of selected dosage, duration of injection, time of injection, whether the pen has been primed or shaken to thoroughly mix up insulin mixtures, transmit information relating to insulin dosage and injection to a data management unit, provide reminders, error warning or messages on improper usage or reusage of needles, track amount of drug remaining on board the pen or duration of usage of pen with respect to expiry of the drug on board, or provide an audible alarm for locating misplaced pen and module.12-22-2011
20120071818Injection Device With A Capacitive Proximity Sensor - An injection device for injecting medication to a patient, comprising a surface (03-22-2012
20120071817STABILIZED GLUCAGON SOLUTIONS AND USES THEREFOR - Stabilized glucagon solutions, methods of storing and using the stabilized glucagon solutions, and drug delivery devices containing the stabilized glucagon solutions. In some embodiments, the glucagon solutions may be alkaline, such as with a pH of at least about 9. The glucagon solutions may be resistant to aggregation of glucagon when the solutions are stored for a prolonged period, such as at least about three days, at room temperature and/or physiological temperature.03-22-2012
