  • Publication number: 20060053036
    Abstract: A system and method for communicating and validating patient information including medication delivery information in a care-giving facility is provided. A medical transaction carrier is used to communicate information regarding medication delivery and other patient information between a control system in communication with the care-giving facility's other information systems and a patient specific asset such as an infusion pump. All information carried by the medical transaction carrier is validated both at the patient specific asset and at the control system. This validation allows for positive control of all transactions even if a medical transaction carrier is lost. The medical transaction carrier may be a smartcard, a PDA such as a Palmâ„¢ Pilot, laptop computer, pager, mobile phone, or other device capable of storing and communicating information. The system may use either wired or wireless connections to communicate information between the components of the system.

  • Publication number: 20060047538
    Abstract: A system and method of managing therapy provided to patients in an institution. The system monitors all aspects of the medication delivery to a patient, as well as other information related to the patient, such as values of vital signs, laboratory results and patient factors such as history, diagnosis, allergies and the like. The system includes one or more databases of information, including institutionally developed rules, guidelines and protocol representing the best medical practices of the institution. The system provides alerts and/or recommendations based on the application of the rules to the information being monitored, and alerts care givers accordingly, providing for dynamic adjustment of the patient's therapy. The system also monitors the status of the alerts, and if no action is taken in a selected period of time, may escalate the priority of the alert and/or halt the delivery of medication to the patient until the alert is resolved.

  • Publication number: 20050224083
    Abstract: A system and method for assessing the severity of medication errors associated with intravenous administration is provided. A harm index database includes harm index values for various parameters of medication administration. A medication administration device may access this database and assess the overall harm index for particular errors in order to provide appropriate alerts based on the severity of the error. Further, assessment of the harm index value may be used retrospectively to provide reports of event logs that include an overall harm index value associated with each alert.

  • Publication number: 20050171815
    Abstract: A system and method for monitoring, managing and controlling medication delivery from a central location is provided. A central computer displays medication orders and ongoing medication administrations for a health care facility. The central computer checks medication delivery against a database of medication administration guidelines, including guidelines for medication interactions with other medications and with patient conditions and provides an indication of any detected incompatibilities. A clinician at the central location may adjust the medication administration parameters in response to detected incompatibilities and communicate with a caregiver at the point of care to provide decision support. In one embodiment, the central location is a pharmacy at the healthcare facility.

  • Publication number: 20050145008
    Abstract: A system and method for determining whether the pressure in a fluid line upstream of an infusion pump is becoming lower as pumping draws fluid from the fluid line and fluid container due to a lack of proper venting. An initial pressure is sensed by an upstream pressure sensor at the start of an infusion. After a period of time, which may be determined either by monitoring infusion time or the number of pump cycles completed, a second pressure is sampled and compared to the initial pressure. Various analytical methods may be applied to the sensed pressures to determine upstream pressures or trends. Where an upstream pressure reading indicates a lack of proper venting, an alert signal is provided. Continuous monitoring may occur in which succeeding samples are compared to preceding samples to determine upstream pressures or trends.

  • Publication number: 20050145009
    Abstract: A system and method for monitoring changes in the pressure of a fluid line upstream of an infusion pump to determine when a fluid container has emptied, and to provide a signal indicating that the container needs replacement or replenishment. The difference between averaged pressures over separate time periods is monitored to determine when the fluid container is empty. The system and method are applicable to primary and secondary fluid container setups and can detect the point where the secondary has been emptied and the primary flow has resumed.

  • Publication number: 20050145010
    Abstract: A system and method determine when fluid is not flowing properly from a secondary infusion source during a secondary infusion. The system includes an upstream pressure sensor and a processor programmed to receive signals from the sensor and analyze the signals to determine if secondary fluid flow is proper. The processor samples the output signals from the upstream pressure sensor and analyzes the sampled signals to determine if a pressure rise in the infusion line has occurred when the secondary infusion is initiated. If a pressure rise, indicating that fluid from the secondary container has begun flowing into the infusion line, has not been detected, the processor is programmed to provide a signal indicating that attention should be given to the infusion set up.

  • Publication number: 20050107923
    Abstract: A system and method for verifying that a particular fluid supply is connected to an infusion pump or pump channel. An upstream pressure sensor coupled to a fluid conduit associated with the fluid supply is used to provide pressure signals in response to pressure sensed in the conduit to a processor. In a connection verification mode, the processor is configured to receive the pressure signals and delay the flow control device of the infusion pump from moving fluid through the conduit until the processor detects a pressure change in the conduit indicated by the pressure signals to thereby verify that the particular fluid supply is connected to the infusion pump.

  • Patent number: 5022538
    Abstract: An apparatus and method for organizing and hanging a plurality of I.V. bags on an I.V. pole includes a solid back and a plurality of spaced apart resilient loops, which apparatus fits over a horizontal support bar on the I.V. pole. The resilient loops are movable between an open position and a closed position. The loops are biased to be in the closed position normally, with a free end of the loop overlapping the top edge of the back. The loop is moved to the open position to place I.V. bags onto the loops, and suspend the I.V. bags at spaced apart intervals in organized fashion. The apparatus includes an unobstructed span having a restraining member to secure the apparatus to the I.V. pole. Some or all loops may include locking members to lock the loops in the closed position.

  • Patent number: 5020562
    Abstract: A multiline check valve assembly has an elongated body which defines a fluid passageway and which is formed with a plurality of valve cavities that are in fluid communication with the fluid passageway. Each valve cavity has a resilient valve element disposed within the cavity and each valve element rests in the cavity with one end against a protrusion disposed in the cavity for centering the element within the cavity. The resilient valve element is biased to urge its other end against a valve seat that surrounds an opening to the valve cavity to create a fluid tight seal with the valve seat and close the opening. In addition, an access port is formed circumferentially around both the valve seat and opening to establish a fluid communication path through the access port to the fluid passageway in the body when the valve element is separated from the valve seat.
