Systems, methods, and devices for humidifying a breathing gas are presented. The system includes a source of pressurized breathing gas, a vapor transfer unit external to the source of pressurized breathing gas, a first gas tube connecting the source of pressurized breathing gas to the gas inlet of the vapor transfer unit and having a first length, a liquid supply having a heater that heats liquid, a first liquid tube coupling the liquid supply to the liquid inlet of the vapor transfer unit, and a second gas tube having a second length and connecting the gas outlet to a patient interface. The first length is greater than the second length. The vapor transfer unit includes a gas passage, a liquid passage, and a membrane separating the gas passage and the liquid passage. The membrane is positioned to transfer vapor from the liquid passage to the gas passage.

The present invention relates to an apparatus for removing, in a manner that is as odor-free as possible, intestinal gas or other malodorous gases as part of a system for the closed, preferably continuous, removal and/or collection of stools or other strongly odor-forming excretions or secretions from the human or animal body, wherein the stool or the removed excretions or secretions are guided outside the body through a hose-like or tube-like structure which, in addition to an inflow port and an outflow port and a passage region that connects said ports and is intended for the passage of stool or other excretions or secretions, has a branch where intestinal gas or other malodorous gases are separated from the stool or the other excretions or secretions and are conducted through an adsorption and/or filter device to an outlet, wherein at least some regions of the adsorption and/or filter device are spaced apart from the passage region in order to prevent, as far as possible, close contact with the stool or other excretions or secretions flowing through the passage region.

A sedation device (1) has a housing (2) having a ventilator chamber (3) and an associated patient chamber (4) in communication with the ventilator chamber (3). A filter (5) is mounted between the ventilator chamber (3) and the patient chamber (4) and forms a common gas-permeable dividing wall between the ventilator chamber (3) and the patient chamber (4). An inlet port (6) is provided on the ventilator chamber (3) for connection via a Y-piece to a ventilator. An outlet port (9) of the patient chamber (4) connects via a patient breathing tube (10) with a patient. An associated pair of inserts are provided, namely a first insert (14) fixedly mounted in the ventilator chamber (3) and a second insert (15) fixedly mounted in the patient chamber (4). One or both of these inserts (14, 15) are mounted within the housing (2) to vary the internal volume of the housing (2) as required to suit different patients. The inserts (14, 15) are nestably engageable with an inner wall of the housing (2).

Drug delivery system including: a reservoir having a meander shape or spiral shape, the reservoir including an inlet and a filter; a capacitance measurement device configured to determine a parameter of the reservoir; and a micropump configured to deliver a fluid from the reservoir to an outlet.

The invention relates to a liquid store for an inhaler (10), in particular for an electronic cigarette product, having an outlet end (53) which can be fluidically connected to a heating element (60) in order to evaporate liquid (50) supplied to the heating element (60) from the liquid store (18). The liquid store (18) has at least one air inlet end (52) and at least one channel (51). The channel (51) extends from the air inlet end (52) to the outlet end (53) through the liquid store (18), wherein the channel (51) is designed to transfer the liquid (50) stored in the liquid store (18) to the outlet end (53) through the channel (51) via capillary forces.

A disposable transfer device has an injection device support surface for receiving an on-body injection device thereon and a flow path arrangement for transfer of fluid into the injection device, the transfer device being configured to define preferential gripping areas for user gripping of an injection device when such device is located on the support surface and interfering areas for interfering with user gripping of the injection device in the interfering areas.

A moisture removal and condensation and humidity management apparatus for a breathing circuit comprises a breathing circuit tubing defining a breathing gas conduit. The breathing gas has a first humidity level and a level of moisture therein. A dry gas conduit is adjacent at least a portion of the breathing gas conduit. The dry gas flow is configured to have a second humidity level lower than the first humidity level. A moisture transmission pathway is provided between the breathing gas conduit and the dry gas conduit, such that humidity in the flow of breathing gas is lowered and moisture is transferred to the dry gas flow. The moisture transmission pathway may be provided by a permeable portion which is permeable to water vapor but impermeable to liquid water, or by one or more perforations which permit drainage of liquid water from the breathing gas conduit to the dry gas conduit.

A Non-Rebreather Exhalation Filtration Device (FD) with a front plastic sheet (PS), an aerosol separator (AS) and optionally a collection reservoir (R) may be fitted (i) (FIG. 3A) by its inlet port (IP) onto a nebulizer exhaust tube (NET), or (ii) by an adhesive layer (AL) onto a respiratory mask (M) having a port (P) and a flat surface (FIG. 5), or (iii) by an adhesive layer (AL) and flexible substrate (FS) onto a respiratory mask (M) having a port (P) and a non-flat (FIG. 6) surface. A deflector (D), stiffener component (SC) and rear plastic sheet (PS2) are disclosed. Methods of using the Filtration Device are disclosed.

A patient interface assembly includes a flexible cushion configured to sealingly engage the patient's nares and a frame with a pair of flexible extending members that extend laterally from opposite sides of the frame. The frame and the flexible cushion together form a chamber. The patient interface assembly also includes a positioning and stabilising structure configured to maintain the flexible cushion in engagement with the patient's nares. The positioning and stabilizing structure has a pair of headgear straps. Each headgear strap is connected to a respective one of the flexible extending members. The flexible extending members do not form an airflow path for the breathable gas. The headgear straps have a multi-layered structure, at least one layer being made of fabric and at least one layer being made of plastic. In addition, the at least one plastic layer is a rigidizer that adds rigidity to the respective headgear strap.
