A patient interface includes: a plenum chamber; a seal-forming structure; a positioning and stabilising structure; a plenum chamber insert configured to be positioned and retained within the plenum chamber; and a vent structure; wherein the plenum chamber insert has a plenum chamber insert port; wherein the plenum chamber insert has an exterior surface configured to be positioned adjacent to an interior surface of the plenum chamber; wherein when the plenum chamber insert is positioned and retained within the plenum chamber, a radial channel is formed by the interior surface of the plenum chamber and the exterior surface of the plenum chamber insert such that gas is able to pass between a patient-proximal side plenum chamber insert and a patient-distal side of the plenum chamber insert via the radial channel during use.

A water reservoir includes a water reservoir base configured to hold a volume of water to be used for humidification of pressurized breathable air, a water reservoir lid connected to the water reservoir base, and a compressible resilient portion configured to seal between the water reservoir base and the water reservoir lid. The base and the lid are movable relative to one another when connected whilst maintaining sealing therebetween due to the compressible resilient portion. A retainer is configured to secure the water reservoir to a water reservoir dock, and has a protrusion or recess to releasably engage one another when the water reservoir is received in the dock, with a reaction force to compression of the compressible resilient portion urging the protrusion and the recess into engagement with one another.

A method for discharging fluid from a syringe and for mitigating occlusion conditions includes actuating the plunger of a syringe into a barrel. The method monitors fluid pressure within the barrel of the syringe and determines that an occlusion exists when the fluid pressure exceeds a predetermined threshold. The method actuates the plunger out of the barrel by a predetermined amount in response to the detected occlusion and actuates the plunger of the syringe into the barrel until a measured fluid pressure within the barrel of the syringe exceeds another predetermined threshold.

A patient interface includes: a plenum chamber; a seal-forming structure; a positioning and stabilising structure; a plenum chamber insert configured to be positioned and retained within the plenum chamber; and a vent structure; wherein the plenum chamber insert has a plenum chamber insert port; wherein the plenum chamber insert has an exterior surface configured to be positioned adjacent to an interior surface of the plenum chamber; wherein when the plenum chamber insert is positioned and retained within the plenum chamber, a radial channel is formed by the interior surface of the plenum chamber and the exterior surface of the plenum chamber insert such that gas is able to pass between a patient-proximal side plenum chamber insert and a patient-distal side of the plenum chamber insert via the radial channel during use.

According to one aspect, there is provided a device (4) for providing supplemental oxygen to a subject (8), the device (4) comprising a subject interface (10) through which the subject (8) can inhale; a container (12) that has a first outlet (18) connected to the subject interface (10) to allow gas with an elevated oxygen level stored in the container (12) to be inhaled by the subject (8), a first inlet (24), and a material (15) for removing a specific gas from air passing through the container (12) to increase the oxygen content of the air passing through the container (12); and an air blower (14) that is connected to the first inlet (24) of the container (12) and that is configured to supply air into the container (12) as the subject (8) uses the device (4).

A plunger for movably mounting within a cavity or barrel of a syringe. The plunger includes a contact face having a flange movably mounted thereto, wherein the flange is movable between an open configuration wherein an opening is formed between the flange and a portion of the plunger, the opening configured for engagement with an IV hook or other engagement member, and a closed configuration wherein the upper surfaces of the contact face and the flange are generally planar with one another.

A first medical device can receive a physiological parameter value from a second medical device. The second physiological parameter value may be formatted according to a protocol not used by the first medical device such that the first medical device is not able to process the second physiological parameter value to produce a displayable output value. The first medical device can pass the physiological parameter data from the first medical device to a separate translation module and receive translated parameter data from the translation module at the first medical device. The translated parameter data can be processed for display by the first medical device. The first medical device can output a value from the translated parameter data for display on the first medical device or an auxiliary device.

The present disclosure relates to a holder for a recording unit, which recording unit is arranged with an interface configured to cooperate with an interface of a medicament delivery device for obtaining information regarding the use of the medicament delivery device, the holder has an interface configured to cooperate with the interface of the recording unit, and the holder further has attachment elements for attaching the holder to a suitable surface.

A filling aid. The filling aid includes a needle housing portion including at least one tab having a starting position and a filling position, and a filling needle cradle including a filling needle, the filling needle cradle slidable connected to the needle housing portion and having a starting position and a filling position, wherein when the at least one tab on the needle housing moves from a starting position to a filling position, the filling needle cradle slides from a starting position to a filling position, and wherein when the at least one tab on the needle housing moves from a filling position to a starting position, the filling needle cradle slides from a filling position to a starting position.

An integrated system for the monitoring and treating diabetes is provided, including an integrated receiver/hand-held medicament injection pen, including electronics, for use with a continuous glucose sensor. In some embodiments, the receiver is configured to receive continuous glucose sensor data, to calculate a medicament therapy (e.g., via the integrated system electronics) and to automatically set a bolus dose of the integrated hand-held medicament injection pen, whereby the user can manually inject the bolus dose of medicament into the host. In some embodiments, the integrated receiver and hand-held medicament injection pen are integrally formed, while in other embodiments they are detachably connected and communicated via mutually engaging electrical contacts and/or via wireless communication.
