Extracorporeal blood treatment systems and methods to detect the connection of one or more components (e.g., of an extracorporeal blood set) thereto (e.g., to one or more pressure transducers contained in the system housing) by, for example, controlling an air pump apparatus to provide air to a connection port at which the component is to be connected and monitoring pressure resulting therefrom to detect whether the component is operatively connected (e.g., based on a detected change in the monitored pressure due to the increased resistance, based on a monitored rate of decay of pressure of injected air, etc.).

A nebulizer assembly for a respiratory device is provided having a housing defining a chamber. The housing also has a nebulizer port configured to receive a nebulizer to discharge atomized medication into the chamber. An outlet of a handle is coupled to the inlet of the housing. A hose is coupled to an inlet of the handle. A patient interface is coupled to the outlet of the housing. Air flows from the hose to the patient interface via the handle and the housing. The air mixes with the atomized medication within the chamber.

Embodiments of negative pressure wound therapy systems, apparatuses, and methods for operating the systems and apparatuses are disclosed. In some embodiments, the apparatus includes a negative pressure source, a connector port, at least one switch, and a controller. The negative pressure source is connected through the connector port to either (i) a wound dressing having a canister configured to store fluid aspirated from the wound or (ii) a wound dressing without a canister between the connector port and the wound dressing. The controller determines, based on a signal received from the at least one switch, whether the canister is positioned in the fluid flow path and adjusts one or more operational parameters of negative pressure wound therapy based on the determination. The switch is activated by the connection of either the canister or canisterless wound dressing to the apparatus.

A fluid handling cassette, such as that useable with an automated peritoneal dialysis (APD) cycler device or other infusion apparatus, may include a generally planar body having at least one pump chamber formed as a depression in a first side of the body and a plurality of flowpaths for a fluid that includes a channel. A patient line port may be arranged for connection to a patient line and be in fluid communication with the at least one pump chamber via at least a first one of said flowpaths, and an optional membrane may be attached to the first side of the body over the at least one pump chamber. In one embodiment, the membrane may have a pump chamber portion with an unstressed shape that generally conforms to the depression of the at least one pump chamber in the body and is arranged to be movable for movement of the fluid in a useable space of the at least one pump chamber. One or more spacers may be provided in the at least one pump chamber to prevent the membrane from contacting an inner wall of the at least one pump chamber. The patient line, a drain line, and/or a heater bag line may be positioned to be separately occludable in relation to one or more solution lines that are connectable to the cassette.

A pump for pumping fluid includes a tube platen, a plunger, a bias member, inlet and outlet valves, an actuator mechanism, a position sensor, and a processor. The plunger is configured for actuation toward and away from the infusion-tube when the tube platen is disposed opposite to the plunger. The tube platen can hold an intravenous infusion tube. The bias member is configured to urge the plunger toward the tube platen.

Systems and methods are provided for detecting and sequestering waste anesthetic gases released by an anesthetic vaporizer. In one embodiment, a method for an anesthetic vaporizer installed in an anesthesia machine includes detecting an emission of waste anesthetic gases (WAGs) from the anesthetic vaporizer, and responsive to detecting the emission of WAGs, performing at least one of scavenging the WAGs and outputting an alert.

The present disclosure relates to aerosol delivery devices and cartridges for aerosol delivery devices. The cartridge comprises a mouthpiece having a proximal end and a distal end, the proximal end of the mouthpiece having an exit portal defined therethrough, a tank defining a proximal end and a closed distal end, the tank being configured to contain a liquid composition that includes a distinctive characteristic, and a heater configured to heat the liquid composition. The distal end of the mouthpiece is configured to engage the proximal end of the tank, and when the cartridge is coupled with the aerosol delivery device at least one feature of the cartridge, or at least one feature of the control device, or at least one feature of both the cartridge and the control device, provides a visual indication of a color associated with the distinctive characteristic.

A humidification system can include a heater base, a chamber, and a breathing circuit. The heater base includes a heater plate positioned in a recessed region, and a heat conductive portion of the chamber is configured to contact the heater plate. The heater base includes a guard configured to control movement of the chamber into and out of the recessed region. The guard includes an anti-racking mechanism. The chamber includes an inlet port, an outlet port. A downward extension extends into the chamber from the inlet port, and a baffle is disposed at a lower end of the downward extension. A component of the breathing circuit can include a conduit hanging end cap for shipping and storage. The end cap can include a hanging component to allow the breathing circuit component to be hung from a medical stand. The system can detect when breathing circuits are connected in reverse.

A battery-operated foam inhalation device which comprises a cartridge (610) having a liquid for producing a foam and a foam outlet (654). Agitation means agitates the liquid to produce the foam, and the agitation means comprises an electric motor (762) and a battery (760) for energising the electric motor (762). A carrier (672) receives the cartridge (610) and has a carrier foam inlet (680) for fluid communication with the foam outlet (654) of the cartridge (610). A carrier foam outlet (682) dispenses the foam to a user.

A case for an electronic cigarette vaporiser, the case including an automatic lifting mechanism that lifts the vaporiser up a few mm from the case to enable a user to easily grasp the vaporiser and withdraw it from the case. The lifting mechanism can be spring- based. The case both re-fills the vaporiser with liquid and also re-charges a battery in the vaporiser.
