An infusion pump can include a syringe receptacle, a retention mechanism, a drive mechanism, and a keyed lock. The retention mechanism can inhibit removal of the syringe from the receptacle when in an engaged state, and enable removal of the syringe when in a disengaged state. The drive mechanism can include a pusher to selectively couple to a thumb press of the syringe, a motor coupleable to the pusher, and a clutch to couple and decouple the motor to the pusher. The keyed lock can operate in coordination with the retention and drive mechanisms such that, if: the keyed lock is locked, the retention mechanism is in the engaged state, and the pusher is coupled to the thumb press of the syringe, then as long as the keyed lock remains locked, the retention mechanism is constrained to the engaged state and the clutch to the coupled state.

A valve assembly comprising a housing and a valve, the valve being disposed within the housing, a first indexed member integral to the housing, the first indexed member adapted to be complementary to a second indexed member, and a radio frequency identification device adapted to communicate with a radio frequency receiver, the valve being configured to align with a canister, seal the canister and open in a single movement. A drug containment device having said valve assembly is also disclosed.

A vaporization device includes a mixer to receive and mix vaporization substances to form a vaporization substance mixture, and an atomizer, in fluid communication with the mixer, to vaporize the vaporization substance mixture. The mixer is an active mixer in some embodiments, and could include a stirring element such as a stirring element that is driven by an electric motor, a magnetic stirring element, or an acoustic stirring element. The mixer could also or instead include a passive mixer with multiple mixing elements to mix the vaporization substances and form the vaporization substance mixture.

The present invention is directed to a system comprising a mobile inhaler (1) that is configured to be connected to at least one liquid container (17), and to deliver an amount of an inhaling substance (10). The mobile inhaler comprises furthermore at least one or a plurality of connector(s) (80) configured for connection of the mobile inhaler to the at least one liquid container and for intaking of at least a portion of the at least one liquid container's content(s). The system comprises furthermore the at least one liquid container, wherein each liquid container comprises at least one reservoir that comprises at least a portion of the inhaling substance or the inhaling substance. The present invention is furthermore directed to a method for operating the system, comprising delivering the inhaling substance by the system according to a set of conditions. Said set of conditions regulates at least one of a quantity and a general delivery of the inhaling substance.

An anesthetic vaporizer system includes a reservoir containing anesthetic agent, an agent level sensor measuring an agent level of the anesthetic agent in the reservoir, a display, and a controller. The controller is configured to receive agent level measurements from the agent level sensor over a time period, and determine the anesthetic agent is being added to the reservoir from an agent source based on the agent level measurements over the time period. A filling status is determined based on the agent level measurements and a filling status indicator is displayed based on the determined filling status.

An apparatus for humidifying a flow of breathable gas includes a water reservoir including a chamber structured to hold a volume of water, a water reservoir dock structured and arranged to receive the water reservoir in an operative position, and a latch movable between (1) a locked position to releasably lock the water reservoir to the water reservoir dock in the operative position, and (2) an unlocked position to allow insertion of the water reservoir into the water reservoir dock and removal of the water reservoir from the water reservoir dock.

A connection device, for mechanical ventilation and monitoring of spontaneous breathing of a patient (P), includes a fluid-guiding unit (9, 11, 15) and establishes a fluid connection between a medical arrangement (100) and a patient-side coupling unit (19). A volume flow sensor (90) measures an indicator of volume flow of fluid through the fluid-guiding unit. A volume flow sensor component (2) engages with an interior of the fluid-guiding unit. A homogenization unit (10) is nonrotatably inserted into the interior between the patient-side coupling unit and the component and includes two sieves and a connection element, which connects the sieves together. The homogenization unit homogenizes the flow of fluid through the fluid-guiding unit. An inner profile of the fluid-guiding unit and an outer profile of the homogenization unit together form a mechanical coding, which determines a defined rotation position of the homogenization unit in relation to the fluid-guiding unit.

An intravenous fluid delivery apparatus (IFDA) includes a body having two or more docks, wherein each dock includes a dock outlet and is configured to engage with a container. The IFDA further includes a fluid interface having two or more interface inlets and an interface outlet, wherein the two or more interface inlets are in fluid communication with the interface outlet, and two or more supply lines, each supply line disposed between one of the dock outlets and one of the interface inlets, wherein the interface outlet is configured to connect with an intravenous line.

A multi-medicament infusion system (10) for preventing the mischanneling of medicaments may include an infusion pump (12), medicament reservoirs (16A,16B), a multi-channel lumen (18), and an infusion set (20). The medicament reservoirs may be sized and shaped differently such that the medicament reservoirs can only be inserted into the infusion pump in a unique configuration. The multi-channel lumen may include connectors that mate to corresponding connectors on the infusion pump and the infusion set only in a unique configuration. Because the various parts of the multi-infusion system may only be connected in the unique configuration, the expected medicaments may be administered appropriately and channeled to the correct infusion sites.

Fluid couplings prevent or discourage misconnection of fluid lines. In embodiments, a coupling device includes multiple male and female connectors that are joined to a common line. The coupling device is mated to a matching coupling device only when all the multiple male and female connectors are properly joined. If any of the connectors is not properly mated to a corresponding one, the coupling will leak, since the connectors on each side are joined to a furcating channel. In embodiments, the coupling devices are made unique by providing an arrangement of the connectors, number of connectors, shape of connectors or arrangement of interfering connector parts that ensure that any attempt to improperly couple two fluid lines will result in the incomplete mating and thereby cause leakage of the fluid, failure of the coupling to engage, or otherwise cause the attempt to connect to fail.
