  • Patent number: 10387617
    Abstract: Embodiments for scheduling the delivery of multiple medications to a patient by a processor. Any interactions between the multiple medications or between one of the multiple medications and a type of food are considered to construct an analytical model to identify an optimized schedule for delivery of the multiple medications to the patient. The optimized schedule is adjusted in real time as additional information concerning the multiple medications and the type of food are introduced, and delivered to a dispensing device associated with the one of the multiple medications.

  • Patent number: 10311536
    Abstract: A method and system may provide an automated pharmacy processing system which automatically processes an electronic prescription by converting the electronic prescription into a pharmacy prescription record. In this way, an electronic prescription can be filled by a pharmacist without manual data entry. The system receives an electronic prescription and compares data from the electronic prescription with entries in one or more pharmacy database(s). When there is a match between the electronic prescription data and an entry in the one or more pharmacy database(s), the system populates the pharmacy prescription record with data from the matching pharmacy database entry. If all of the data fields from the pharmacy prescription record have been populated the pharmacist can fill the electronic prescription.

    Abstract: This disclosure describes systems and methods for monitoring and evaluating ventilatory data to provide useful notifications and/or recommendations. Indeed, many clinicians may not easily identify or recognize data patterns and correlations indicative of certain patient conditions or the effectiveness of ventilatory treatment. Further, clinicians may not readily determine appropriate adjustments that may address certain patient conditions or the effectiveness of ventilatory treatment. Specifically, clinicians may not readily detect or recognize the occurrence of high-delivered VT, during various types of ventilation. According to embodiments, a ventilator may be configured to monitor and evaluate diverse ventilatory parameters to detect an occurrence of and potential causes for high-delivered VT, and may subsequently issue suitable notifications and/or recommendations.

  • Patent number: 8814806
    Abstract: A device for detecting the condition of flow in a respiration system combines the function of a nonreturn valve with the function of flow measurement in a common device. The device includes a valve arrangement (1) with a valve disk (9) and with a valve body (8), wherein the position of a valve disk (9) in relation to a valve seat (11) is detected. An indicator for a flow and a direction of flow (5), (6) is determined from the position of the valve disk (9). The position of the valve disk (9) can be determined inductively, electrically, electromechanically or optically. The flow and direction of flow (5), (6) determined can be used to control the respiration in a medical device.

  • Publication number: 20140190485
    Abstract: Methods and systems are provided that determine whether a patient is receiving minimal support from a ventilator. In one embodiment, a ventilation system may determine a value of a peak inspiratory pressure (PIP) and a value of a positive end-expiratory pressure (PEEP) of a patient. The ventilation system may determine a pressure differential between the value of PIP and the value of PEEP and compare the pressure differential to a threshold. The ventilation system may determine that the patient is receiving minimal support if the pressure differential is below the threshold. Further, the ventilation system may provide an indication of the detection of minimal support.

    Abstract: Methods and systems are provided that determine whether a patient is asynchronous with a ventilator. In certain embodiments, a ventilation system may determine whether a double-triggering event has occurred between the patient and the ventilator. The ventilation system may compare a value of the patient's exhaled tidal volume to a threshold and may determine that a double-triggering event occurred if the patient's exhaled tidal volume is less than or equal to the threshold. The ventilation system may also determine a frequency of the double-triggering events. Further, the ventilation system may provide an indication of a detected double-triggering event and an indication of the frequency of double-triggering events.
