An apparatus is described for extracorporeal blood treatment (1), comprising a treatment unit (2), an extracorporeal blood circuit (8) and a fluid evacuation line (10). The apparatus comprises a control unit (21) connected with a pressure sensor (13, 14) and with a blood pump (9) and configured to move the blood pump (9), generating a variable flow with a constant component equal to a desired blood flow value and a variable component having a nil mean value; the variable flow generates, in the expansion chamber (11, 12), a progression of the pressure that is variable over time (P(t)) with a pressure component (P) oscillating about a mean value (P.sub.avg). The control unit receives, from the sensor, a plurality of values (P.sub.j) over a period of time (T) comprising a plurality of oscillations of the pressure about the mean value and calculates, according to the pressure values (P.sub.j), a control value that is representative of the oscillating pressure component (P) and then compares the control value with a reference threshold to determine the verification or not of a condition of variation of the blood level in the expansion chamber (11; 12).

A portable hemodialysis system is provided including a disposable cartridge and a reused dialysis machine. The disposable cartridge includes a dialysate flow path and a blood flow path which flow in opposite directions through a dialyzer. The disposable cartridge further includes a filter for removing waste products from the dialysate as well as one or more flow sensors for measuring the flow of dialysate in the dialysate flow path. The preferred flow sensor includes a rotatable spoked wheel in the dialysate flow path which is rotated by the flow of dialysate. The spoked wheel includes one or more magnets which are rotated with the rotation of the spoked wheel. The flow sensor further includes a magnetic field sensor in the reused dialysis machine which is connected to a processor for monitoring the rotation of the spoked wheel to determine flow of fluid in the dialysate flow path.

A device and method for delivering a fluid as an ejected stream of droplets during inhalation uses inertial filtering to cause a first plurality of droplet particles generated by an ejector mechanism to pass through an airflow exit while a second plurality of droplet particles having a greater mass mean aerodynamic diameter than the first plurality of droplet particles fails to pass through the airflow exit.

The present invention is generally related to a device and method for sanitizing a medical instrument with ozone, in particular the invention relates to a system, method and a device for sanitizing a continuous positive airway pressure (CPAP) device. The device has an ozone compartment, an ozone operating system and one or more ozone distribution lines that distribute ozone to a continuous positive airway pressure device. The device may further include a heater adapter unit to connect heating systems in CPAP devices while distributing ozone to sanitize the CPAP device in accordance with the present invention.

A device for generating and delivering Nitric Oxide (NO) to a treatment site includes a main unit, an applicator, a connector hose, and a mobile stand. The main unit provides power and a gas to the applicator via the connector hose. The applicator includes a plasma generator for generating NO in a plasma state. The main unit including a user interface to enable a user to control at least one operational aspect of the device. The applicator includes a pistol grip handle, a trigger for actuating the plasma generator, a hose connection for coupling to the connector hose, and a cowl portion for spacing a tip of the plasma generator at a predetermined distance from a treatment site. Sensors are provided with the applicator for sending feedback and monitoring application site temperature, proximity to the application, applicator motion and the like.

Systems and methods for automatically delivering medication to a user. A sensor coupled to a user can collect information regarding the user. A controller can use the collected information to determine an amount of medication to provide the user. The controller can instruct a drug delivery device to dispense the medication to the user. The drug delivery device can be a wearable insulin pump that is directly coupled to the user. The controller can be part of or implemented in a cellphone. A user can be required to provide a confirmation input to allow a determined amount of insulin to be provided to the user based on detected glucose levels of the user. The sensor, controller, and drug delivery device can communicate wirelessly.

A control body is coupled or coupleable with a cartridge that is equipped with a heating element and contains an aerosol precursor composition, the control body and cartridge forming an aerosol delivery device. The control body includes a control to control the heating element to activate and vaporize components of the aerosol precursor composition. The proximity sensor detects a presence of an object nearby the control body without requiring any physical contact with the object. And the proximity sensor or control component controls operation of at least one functional element of the aerosol delivery device in response to the presence of the object so detected. In another aspect, a cartridge may include a proximity sensor to detect a level of the aerosol precursor composition, and operation of functional element(s) may be controlled in response to the level of the aerosol precursor composition so detected.

A method and apparatus are provided for automatically detecting the type of replacement fluid loaded by the operator during a therapeutic exchange procedure and to provide a warning alarm if an incorrect fluid is used. After the operator connects the container of replacement fluid to the replacement fluid line of a single-use kit and enters into the controller an identification of the exchange procedure to be performed, the replacement fluid is flowed through a segment of the kit in proximity to a sensor associated with the hardware component that detects the type of fluid flowing through the segment. The controller verifies whether the replacement fluid detected in the segment corresponds to that appropriate for the selected exchange procedure, and notifies the operator in the event that an incorrect replacement fluid has been loaded.

Provided is an auto-injector for a syringe suitable for the injected delivery of drug to a patient. The auto-injector comprises a cassette unit arranged for receipt of a syringe. The cassette unit and/or syringe is movable from a rest position, in which the syringe needle tip is within the drive unit housing to a use position, in which the needle tip protrudes from a needle delivery aperture thereof. The auto-injector comprises a drive unit arranged for docking receipt of the cassette unit at a docking position and a drive arrangement. The drive unit is arranged for initial receipt of the cassette unit at an intermediate pre-docking position and for subsequent transport of the cassette unit to the docking position. In embodiments, the drive unit is arranged such that transport of the cassette unit to the docking position is permitted only following verification of an identifier at the intermediate pre-docking position.
