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.

The present invention provides a connector for push-connecting a cartridge containing vaporizable material, such as a 510-cartridge, to a power-supplying device. The connector includes a housing containing electrical contacts, a cartridge-receiving end for receiving a conductive end of the cartridge, and a flexible, preferably silicone, ring connected to the cartridge receiving end of the housing for retaining the conductive end of the cartridge inserted therethrough against the electrical contacts. The ring is preferably part of a silicon boot that houses the housing.

A humidifier assembly is configured to humidify a pressurized flow of breathable gas from a flow generator of a CPAP unit and includes a base configured to be attached to the flow generator, the base including a recess portion. A water receptacle is configured to be received within the recess portion of the base and includes a floor and a flange around an opening at the top of the water receptacle. A lid is hingedly attached to the base and is configured to pivot between an open position and a closed position. This lid includes a top wall, an outer depending wall, an inner depending wall in the form of a double wall, and an outlet pipe. A lid seal is attached to an underside of the top wall of the lid by way of a tongue and groove structure. A catch is located on the base and configured to lock the lid in the closed position.

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.

A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the the one or more lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.

A ventilator system (10) includes a ventilator source (12), camera (14), database (16) and controller (16). A first plurality of ventilation components in a ventilation circuit (34) are coupled between the ventilator source and a patient. The camera captures images of the ventilation circuit. The database includes multi-view images of a second plurality of ventilation components pre-approved for use with the ventilator source. The controller (16) includes (i) a control module (22), (ii) a component recognition and identification module (24), (iii) a component tracking module (26) configured to track targets and to detect at least one change in tracked targets, and (iv) a ventilation compensation module (28). An operation of the ventilator source (12) is controlled with operating parameters determined as a function of at least (i) a gas composition algorithm, (ii) an output of the component recognition and identification module (24), and (iii) an output of the ventilation compensation module (28) determined as a function of an output of the component tracking module (26).

An administration instrument includes an injection button which can be pressed at an angle that is not parallel to a needle with respect to a direction in which the needle is inserted into skin. As a result, it is possible to prevent a force of pressing the injection button from being transmitted in the direction in which the needle is inserted into the skin deeper than initial insertion of the needle, thereby achieving an administration under a stable state.

A trap bowl is provided to accumulate liquid droplets from a filter, as a liquid content. The trap bowl includes a transparent vertical prism. The transparent vertical prism includes a face that forms a vertical transparent surface facing against a content of the section. The face can provide a first angle of total reflection when content of the section is a type of gas, and a second angle of total reflection when the content of the section is the liquid content. A light source may emit a light beam incident on the face at an angle of incidence. The angle of incidence results in reflection of the light beam, striking the light receiver, when the face has the first angle of total reflection, and results in refraction of the light beam, missing the light receiver, when the face has the second angle of total reflection.

Provided is a method that includes automatically providing air/oxygen at a pre-selected maximum pressure limit, breath volume and respiratory-rate. The pre-selected maximum pressure limit, breath volume, and respiratory-rate are automatically set as a function of a size of a mask coupled to an air/oxygen supply system. Further provided is a ventilator system that includes a ventilator mask, a ventilator supply system, and a mask conduit. The ventilator mask is configured in a size that will fit upon a selected range of sizes of human faces. The ventilator supply system includes an air/oxygen source and an air/oxygen regulator system configured to regulate air/oxygen flow parameters as a function of the size of the mask. The mask conduit is configured to couple the ventilator supply to the ventilator mask.

Provided is an aerosol generating system including a holder configured to generate aerosol by heating a cigarette; and a cradle including an inner space into which the holder is inserted. The holder is configured to be tiltable with respect the cradle. The holder is inserted into the inner space of the cradle and then tilted to generate the aerosol.
