Disclosed is a method of controlling operation of a medical device that regulates delivery of a fluid medication to a user. The method receives meter-generated values that are indicative of a physiological characteristic of the user, and are produced in response to operation of an analyte meter device. The method obtains sensor-generated values that are indicative of the physiological characteristic of the user, and are produced in response to operation of a continuous analyte sensor device, different than the analyte meter device. The medical device is operated in different modes when: a valid meter-generated value is available; a valid meter-generated value is unavailable and a current sensor-generated value satisfies first quality criteria; or a valid meter-generated value is unavailable and the current sensor-generated value satisfies second quality criteria but does not satisfy the first quality criteria.

A portable modular assistive device for storing, measuring, drawing and administering liquid injectable medication or other fluids from a vial and syringe, specifically to insulin for consumers and medical professionals in homes, while traveling and in medical facilities, having means to allow users to quickly, securely, easily and accurately measure and draw the desired amount of insulin and then administer the medication. The device is a portable syringe guide and vial holder comprising a horizontal elongated stabilizer made of rigid light-weight material with high tolerance and low friction, a rigid liquid medication vial protector at one end; a rigid movable syringe carriage with an opening on the top side to firmly hold the assembled syringe and needle to perfectly align the needle to the center section of the rubber top of the vial; a flexible expandable color-coded security strap; a flexible expandable color-coded resistance spacer ring, a removeable adjustable magnifier and calibrator bar, a rigid end cap at the other end of the horizontal stabilizer, with said holder having means to allow users to transport said holder in a pocket or pouch without risk of spillage from the vial, dislodging the components or damage to the vial, needle or syringe. Thus, a considerably more versatile, cost-effective, durable and efficient syringe guide and vial holder is provided that can accommodate a plurality of syringe and needle sizes as well as various liquid medications and other fluids in vials in the first embodiment as well as in other embodiments with ease of tracking quantities, contents, sizes and locations of a variety of vials, syringes and needles.

A robot-connected IoT-based sleep-caring system includes a sleep-caring robot and an IoT system. The sleep-caring robot includes environment monitoring, physiology monitoring, sleep monitoring, sound, lighting and electricity control, a smart storage compartment, central data processing, and machine arms. The IoT system senses and executes instructions from the sleep-caring robot, thereby catering to bedroom activities of the user.

Systems and methods for calibrating oxygen sensors in ventilators are provided. An oxygen sensor is coupled in flow communication with a first oxygen gas source. A calibration circuit including a second oxygen gas source is coupled in flow communication with the oxygen sensor and a third oxygen gas source is coupled in flow communication with the oxygen sensor. A controller is configured to determine a calibration curve for the oxygen sensor via the calibration circuit by measuring the second oxygen gas source and the third oxygen gas source. Based on the calibration curve, an oxygen concentration value of the first oxygen gas source is measured and distributed.

A method includes receiving, from a first sensor, first physiological data associated with a first sleep session of a user. The method also includes receiving, from a sensor, second physiological data associated with a first sleep session of a user. The method also includes determining a first set of sleep-related parameters associated with the first sleep session of the user based at least in part on the first physiological data. The method also includes determining a second set of sleep-related parameters associated with the first sleep session of the user based at least in part on the second physiological data. The method also includes calibrating the second sensor based at least in part on a comparison between the first set of sleep-related parameters and the second set of sleep-related parameters.

The drip monitoring system comprises a weighing device to measure a carrying weight. The weighing device includes a gravity sensor to sense a motion data of the weighing device. The processing element gathers the carrying weight to compare with an empty weight. The processing element gathers the motion data of the weighing device when the carrying weight is less than the empty weight. The processing element determines whether the weighing device is in a calibration orientation or not according to the motion data. When the weighing device is in the calibration orientation, the processing element controls the weighing device to perform a return to zero calibration process.

The invention concerns an injector device (100), comprising access means (110, 115) configured to selectively allow and prevent a cartridge (120) storing a pharmaceutical product (122) from being removed from the injector device (100), a self-test unit (130) configured to cause a self-test of at least one of an electronic component and an electronic assembly of the injector device (100), and a control unit (140) configured to control the access means (110, 115) to allow the cartridge (120) to be removed from the injector device (100) in case the self-test has failed.

A patient ventilation interface has a throat body defining a venturi throat that is open to ambient air, a nasal pillow disposed around the venturi throat to define a plenum between the venturi throat and the nasal pillow, a jet nozzle arranged to output ventilation gas into the venturi throat, and a pressure sensing tube having a pressure sensing port positioned to be in fluid communication with the plenum. The nasal pillow may be an integral part of the throat body. An expected error in the sensed patient airway pressure P.sub.sense may be corrected by applying a correction factor P.sub.delta indexed by the sensed patient airway pressure P.sub.sense and a jet nozzle flow V′.sub.n of the jet nozzle. Delivery of the ventilation gas output by the jet nozzle may be controlled in response to the corrected patient airway pressure.

A power supply unit for an aerosol inhaler includes: a power supply that is able to discharge power to a load for generating an aerosol from an aerosol source; and a control unit that is configured to control the power supply. The control unit acquires a deteriorated state or a failure state of the power supply based on an internal resistance of the power supply.

The present invention relates to systems and methods for in situ inspection, interrogation, and maintenance of heart pump function in subjects with an implanted heart pump. In certain embodiments, the system comprises a catheter assembly deliverable to the inflow port and outflow port of the implanted heart pump. The system comprises additional components used to examine pump function and prevent malfunction. In certain embodiments, the invention allows for temporary, mid-term, or permanent exclusion of the implanted heart pump from cardiac function without surgically removing the pump.
