The transfer function generates sensor measured values as a function of primary signal. In a later sensor calibration, sensor measured values provided on the sensor module interface are registered as a function of supplied pressure values and stored in a calibration database. In a later electronics module calibration, measured value signals provided on the signaling interface are registered as a function of sensor measured values supplied by means of a calibration signal source and stored in a calibration database, wherein the supplied sensor measured values correspond to the sensor measured values of the sensor calibration. Finally, there follows the calibration protocol creation, in which the measured value signals ascertained in the electronics module calibration are associated with the pressure values supplied in the sensor calibration.

    Abstract: A method of dispensing fluid includes three processes. A first one of these processes includes pumping fluid into a resilient variable-volume dispensing chamber. The dispensing chamber is in series with a normally present finite fluid impedance and an output. The impedance is sufficient so as to cause expansion of the dispensing chamber as it receives pumped fluid even while some fluid flows through the output. Another one of these processes includes repeatedly measuring a parameter related to volume of the dispensing chamber over time. A third one of these processes includes controlling the pumping of fluid based on repeated measurements of the parameter to produce a desired fluid flow through the output. A corresponding system for dispensing fluid implements these processes.

  • Patent number: 10028762
    Abstract: The NEEDLE KNIFE APPARATUSES, METHODS AND SYSTEMS (“NK”) may have a cannula, through which a needle knife may be deployed. The needle knife may oscillate to cut through a patient's tissue, such as muscle tissue in the forehead of a patient to eliminate forehead wrinkles. In certain embodiments, the knife portion of the needle knife is normally sheathed within a cannula during insertion into and removal from a patient. The oscillation may be performed manually or by a motor, which may be attached via a connection mechanism. The connection mechanism may include a colley system or be glued in place. Once inserted into a patient, the oscillating motor mechanism is engaged to rapidly oscillate the needle knife to expose the knife to rapidly cut soft tissue.

  • Patent number: 9820916
    Abstract: A flow control apparatus adapted to receive a feeding set includes a housing capable of receiving at least a portion of the feeding set. A pumping device is supported by the housing and positioned to contact the feeding set when the feeding set is received by the housing so the pumping device acts on the feeding set to produce fluid flow in the feeding set for delivery of fluid to a subject. An ultrasonic sensor is supported by the housing and arranged with respect to the pumping device to produce a sensor signal indicative of a viscosity of the fluid delivered through the feeding set. A control circuit is in communication with the ultrasonic sensor for receiving the sensor signal from the sensor indicative of the viscosity of the fluid and in communication with the pumping device to control operation thereof.

  • Patent number: 9545472
    Abstract: An extracorporeal reservoir device including a housing, a venous inlet sub-assembly, and a venous filter. The venous sub-assembly is mounted to the housing and includes a downtube and a luer port connector body. The connector body extends from the downtube and forms a passageway open to a lumen of the downtube. The connector body is arranged such that fluid flow from the passageway merges with a flow path of fluid along the primary lumen at an angle of less than 90°. Secondary blood flow through the port connector body is less likely to induce turbulent flow into venous blood flow within the downtube, and is thus less likely to break up any bubbles carried by the venous blood. For example, at port flow rates of less than 500 mL/minute, fluid flow from the port connector body does not induce turbulent flow into fluid flowing through the primary lumen.
