Systems, apparatuses, and methods for utilizing a dressing having a single manifold fluidly coupled to at least two therapy units in a negative-pressure therapy and/or instillation therapy environment as set forth herein. In one example embodiment wherein the therapy system comprises two therapy units, apparatus and methods may be utilized for alternately applying pressure or fluids to a single tissue site to more quickly remove large amounts of fluid from the tissue site.

An aerosol delivery system that includes an aerosol generator that aerosolizes a fluid for delivery to a patient as a patient inhales. The aerosol delivery system includes a pump coupled to the aerosol generator that pumps the fluid to the aerosol generator, and a breath sensor that emits a signal as the patient breathes. A controller couples to the aerosol generator, the pump, and the breath sensor. In operation, the controller receives the signal from the breath sensor, controls a flow of fluid to the aerosol generator in response to the signal, and controls the aerosol generator to start aerosolizing the fluid before the patient inhales.

The present disclosure relates to a medication delivery device having a dose detection system and an associated control system configured to determine an amount of medication delivered from the medication delivery device based on the sensing of relative rotation within the medication delivery device. The relative rotation may occur between a dose setting member and an actuator and/or housing of the medication delivery device. The rotation sensing may involve sliding contact sensing. A latch circuit may be coupled between the rotational sensor and the controller. The dose detection system may be a modular or integral component of the medication delivery device.

A ventilator for use with alternative hose systems. The ventilator comprises at least one respiratory gas source, at least one respiratory gas path, at least one appliance outlet, an appliance inlet and a gas control device for presetting the ventilator for use of the alternative hose systems by switching at least one switching mechanism The gas control device is configured for use of a hose system which is a leakage system, for opening the respiratory gas path (bypass) for a respiratory gas flow.

A remote controller updating system for an implantable blood pump including an implantable blood pump, an implantable controller coupled to the implantable blood pump, and a pump driveline including a data network connection in communication with the implantable controller. The system may also include a pump connector coupled to the pump driveline, a remote controller couplable to the implantable blood pump, and a system update assembly including a system update connector couplable to the pump connector and a power source coupled to the system update connector.

Therapy gas delivery systems that provide run-time-to-empty information to a user of the system and methods for administering therapeutic gas to a patient. The therapeutic gas delivery system may include a gas pressure sensor attachable to a therapeutic gas source that communicates therapeutic gas pressure data to a therapeutic gas delivery system controller, a gas temperature sensor positioned to measure gas temperature in the therapeutic gas source that communicates therapeutic gas temperature data to the therapeutic gas delivery system controller, at least one flow controller that communicates therapeutic gas flow rate data to the therapeutic gas delivery system controller, at least one flow sensor that communicates flow rate data to the therapeutic gas delivery system controller, and at least one display that communicates run-time-to-empty to a user of the therapeutic gas delivery system. The therapeutic gas delivery system controller of the system includes a processor that executes an algorithm to calculate the run-time-to-empty from the data received from the gas pressure sensor, temperature sensor, flow controller and flow sensor, and directs the result to the display.

A monitoring system (9) performs a method for detecting a disruption of a fluid connection between a first fluid containing system and a second fluid containing system. The monitoring system generates a monitoring signal (M1) which is representative of a fluid pressure in respect of the first fluid containing system and which is responsive to the disruption of the fluid connection, and a tracking signal (T1) which corresponds to and is more smoothed over time than the monitoring signal (M1). The monitoring system (9) further sets a detection range (M1L, M1H) in a given relation to the tracking signal (T1) so that the detection range (M1L, M1H) follows changes in the tracking signal (T1), and detects a condition indicative of the disruption by comparing a current pressure value of the monitoring signal (M1) to the detection range (M1L, M1H). The monitoring system (9) may be connected to or part of an apparatus for blood treatment and operable to detect a disconnection of an extracorporeal blood circuit from a vascular system of a patient, e.g. downstream of a blood pump in the extracorporeal blood circuit.

The present invention relates to a dialysis machine having a dialyzer, an extracorporeal blood circuit, a dialysis solution circuit, and a control unit, wherein a blood leak sensor is arranged downstream of the dialyzer in the dialysis solution circuit, wherein the control unit is configured to initiate an error routine when the signal of the blood leak sensor shows an indication of a presumed blood leak, and wherein a further sensor is furthermore arranged downstream of the dialyzer in the dialysis solution circuit, wherein the control unit is configured to use the signal of the further sensor correlated in time with the signal of the blood leak sensor as a suppression criterion for the initiation of the error routine.
