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.

Provided is a system including a plurality of inhalers that each include a processor configured to determine a value of a usage parameter relating to use of the respective first inhaler, encrypt data based on the value, and transmit the encrypted data. At least two of the inhalers include different medicament, such as a rescue medicament and a maintenance medicament. The system includes an external device that includes a processor configured to distinguish between the encrypted data of each respective inhaler, determine respective usage information relating to each of the distinct types of medicament based on the respective encrypted data, and control a user interface (e.g., of the external device) to communicate the usage information related to each inhaler and/or each respective type of medicament.

Negative pressure wound therapy systems, apparatuses, and methods for operating the systems and apparatuses are disclosed. In some cases, the system can include a dressing having electronic circuitry that wirelessly communicates a dressing identifier and/or other dressing information to a controller of a pump assembly of the system. The controller can automatically modify one or more operational parameters of the pump assembly based on the dressing identifier and/or other dressing information wirelessly communicated. Duration of time over which the dressing has been in use can be monitored and provision of therapy by the pump assembly can be disabled responsive to a determination that the duration of time has reached operational lifetime of the dressing.

The invention relates to a connection element (1) for a blood treatment device, in particular for a dialysis machine. The connection element (1) has here an inlet line (2), for letting in a fluid into the connection element (1), an outlet line (3), for letting a fluid out of the connection element (1), at least a first discharge line (21), for discharging a fluid from the connection element (1), wherein the first discharge line (21) is formed in a subsection (22) around the inlet line (2), and wherein the inlet line (2) and the first discharge line (21) are open to a first end section (23) of the connection element (1), and the first end section (23) is fluidically connected with the subsection (22).

The present invention provides an inhalation device with which it is possible to improve usability and promote users' safety and satisfaction with the inhalation device. An inhalation device according to the present invention is provided with a first member and a second member which is configured to be capable of being attached to and detached from the first member. This inhalation device includes: an active functional part which is provided to the first member; a passive functional part which is provided to the second member and which is capable of changing the state thereof according to the working of the active functional part; a sensor part which is provided to the first member and which detects a changed state of the passive functional part; and a control part which, on the basis of the detected state, determines whether the second member has been attached to the first member.

An IV set includes an IV component and a duration monitor device coupled to the IV component. The duration monitor device may include an indicator portion configured to change color after a determined amount of time upon activation of the indicator portion, or an RFID tag configured to be detected by an RFID reader. The duration monitor is configured to provide an indication of passage of a useful-life time period for the IV set or the IV component. Methods of operating a duration monitor device are also provided.

The present disclosure relates to a method of pairing an electronic data logging device of a drug delivery device with an external electronic device and to a respective drug delivery device. The drug delivery device comprises a housing configured to accommodate the medicament and to receive and/or mechanically engage with the electronic data logging device. The drug delivery device further comprises a first device component and a second device component. The first device component is movable relative to the second device component from a first positional state to a second positional state. The first device component comprises a first outer surface, and the second device component comprises a second outer surface. At least one of the first outer surface and the second outer surface comprises a first code portion of a pairing code for establishing a communication link between the electronic data logging device and an external electronic device.

Embodiments of negative pressure wound therapy devices and methods for controlling and operating such devices are disclosed. A negative pressure wound therapy apparatus can include a housing, a negative pressure source, controller, and output device supported by the housing. The negative pressure source can couple via a fluid flow path to a wound dressing and provides negative pressure to the wound dressing. The controller can operate the negative pressure source to provide negative pressure to the wound. The output device can provide identification data to an electronic device, and the identification data can be usable by the electronic device to access a label associated with the negative pressure wound therapy device.

Embodiments of negative pressure wound therapy systems, apparatuses, and methods for operating the systems and apparatuses are disclosed. In some embodiments, a medical device is configured to detect an identity of a patient-contacting disposable connected to the medical device. The medical device automatically modifies one or more operational parameters of the medical device based on the identity of the patient-contacting disposable connected to the medical device. The medical device can include a user interface and modify automatically available selections in the user interface based on the identity of the patient-contacting disposable connected to the medical device.

A nebulizer device aerosolizes (or vaporizes) liquid drawn from a liquid reservoir via a fluid flow path into a nebulization chamber. An inlet port is coupled to an external air supply and leads through a check valve and Venturi nozzle (e.g. a duckbill valve) into the chamber to direct an air stream across an opening of the fluid flow path. A discharge port leads from the chamber to a user mask, mouthpiece or canula, where the aerosol or vapor mixture can be inhaled. A filtered outlet port isolates exhaled material from the external environment. Multiple discrete heating elements may be placed around the fluid flow path to preheat the liquid. If the liquid is sufficiently volatile, heating may vaporize the material which can condense back into an aerosol after mixing with the air stream. A set of check valves direct one-way fluid flow and prevent leakage or spillage of material from the device.
