Expiration system for a patient interface, comprising at least two walls, wherein the walls are arranged next to one another at least in certain sections. The expiration system has at least two flow paths for the flow of respiratory gas out of an interior of the patient interface, wherein the first flow path at least partially runs between the first wall and the second wall and the first flow path is configured for at least intermittently reducing respiratory gas pressure and wherein the second flow path is at least partially enclosed by the second wall and the second flow path is at least partially configured for the at least intermittent flow of respiratory gas into the interior of the patient interface.

An electronic module for releasable attachment to a drug delivery device is disclosed. The module may comprise at least one module lockout form adapted for mating abutment with a corresponding device lockout form of the drug delivery device. The module may comprise at least one attachment element for releasable attachment of the module on the drug delivery device. The module may comprise at least one light pipe for guiding a light beam from a light source to a reflective surface of the drug delivery device and from the reflective surface to a light detector sensor. The module may comprise at least one light guide for guiding a light beam from a light source to a user feedback surface adapted to emit light. The module may comprise at least one elastically deformable switch arm. The component may be a unitary component part injection molded from a polycarbonate material.

The present disclosure relates to a system for temperature management for patients in stationary and mobile ECLS and/or ECMO therapy, with a disposable and a fluid circuit, wherein the disposable comprises a reservoir or bag provided with at least one supply line and a drain line, further comprising a pumping unit element as part of the disposable, by means of which liquid in the reservoir or bag can be pumped through the fluid circuit, wherein in the mounted state of the system all fluid-guiding parts of the system are completely encapsulated and separated from intracorporeal and extracorporeal blood circuit of the patient undergoing the ECLS and/or ECMO therapy.

The present disclosure relates to an aerosol delivery device that includes a reservoir housing that defines a mouthpiece channel. The aerosol delivery device includes a sealing member configured to be received within the reservoir housing to define a reservoir chamber configured to retain an aerosol precursor composition therein. The aerosol delivery device also includes a substrate member that is configured to be received within the reservoir housing and to be directly engaged with a vaporizing assembly for forming an aerosol. The reservoir housing, sealing member, substrate member, and/or vaporizing assembly can be used for forming aerosols with precise and reproducible compositions.

An anesthetic equipment storage and waste air management module configured to housing electronic and electromechanical surgical equipment including a system to measure and record administration of one or more IV medications or fluids for IV administration. The module can include a housing having a lower section and a tower-like upper section, wherein the lower section is configured to house unrelated waste heat-producing electronic and electromechanical surgical equipment. The module can also include a cowling that substantially confines waste heat generated by the unrelated waste heat-producing electronic and electromechanical surgical equipment, and can include a system for measuring and recording the administration of the one or more IV medications and fluids.

A user interface of a respiratory therapy system includes a strap assembly, a frame, a connector, and a sensor. The strap assembly is positioned about a head of a user when the user wears the user interface. The frame is physically and electrically connected to the strap assembly, and defines an aperture. The connector has a first end portion and second end portion. The first end portion of the connector can be positioned within the aperture of the frame such that the connector is physically and electrically connected to the frame. The sensor is coupled to the strap assembly or the frame such that the sensor abuts a target area of the user when the user wears the user interface.

A clamping module of or for a medical pump, and a method for identifying a hose clamp of a disposable infusion article insertable into the clamping module. The clamping module includes an electro-optical system for identifying the hose clamp, which has an optical marking. The electro-optical system includes a first light source for emitting at least a first light beam and a second light source for emitting at least a second light beam. The second light source is formed differently than the first light source. A photodetector receives a reflected light, and an optical window bundles the first light beam and/or the second light beam on the disposable infusion article, as well as the reflected light received by the photodetector. The method identifies the hose clamp based on a color and uses a measurement algorithm after insertion of the hose clamp into the medical pump.

The present disclosure relates to an aerosol delivery device that includes a reservoir housing that defines a mouthpiece channel. The aerosol delivery device includes a sealing member configured to be received within the reservoir housing to define a reservoir chamber configured to retain an aerosol precursor composition therein. The aerosol delivery device also includes a substrate member that is configured to be received within the reservoir housing and to be directly engaged with a vaporizing assembly for forming an aerosol. The reservoir housing, sealing member, substrate member, and/or vaporizing assembly can be used for forming aerosols with precise and reproducible compositions.

A locking mechanism is provided for use with a reservoir and a reservoir holder so as to prevent unwanted tampering with the reservoir. The mechanism comprises a main body with an aperture that is coupled to the reservoir. A hinged flange is provided on the main body. The flange folds inwards at the pivot point provided by the hinge, toward the aperture of the main body, allowing the mechanism to pass over the ferrule of the reservoir. Once the mechanism is placed over the cartridge, the flange folds toward the reservoir at the pivot point, flexing away from the main body. The flange rests against the underside of the reservoir ferrule, thereby retaining the reservoir within the locking mechanism. The locking mechanism may be for use with either a disposable or a reusable delivery device.
