Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In one embodiment, a negative pressure wound therapy apparatus can include a wound dressing, a negative pressure source, and a controller. The negative pressure source can provide negative pressure via a fluid flow path to the wound dressing. The controller can monitor a rate of fluid removal from the wound, wirelessly communicate the rate of fluid removal to a remote device, and output an indication when the rate of fluid removal meets a threshold.

A perfusion system includes a fluid reservoir configured to hold a portion of fluid, the portion of fluid having a volume, the fluid reservoir having a total capacity that is greater than the volume; an imaging device, the imaging device configured to obtain image data corresponding to the fluid reservoir; and a controller. The controller is configured to receive the image data from the imaging device; determine the volume based on the image data; and facilitate control, in response to at least one of a user input and the determined volume of the portion of fluid, of an operating parameter corresponding to the fluid reservoir to facilitate changing or maintaining the volume of the portion of the fluid.

Methods and systems are provided for delivering anesthetic agent to a patient. In one embodiment, an anesthetic vaporizer includes a sump configured to hold a liquid anesthetic agent; an ultrasonic transducer coupled to a bottom of the sump and at least partially disposed within the sump; a vaporizing chamber fluidically coupled to the sump; and a heating element coupled to the vaporizing chamber and configured to increase a temperature of a surface disposed within the vaporizing chamber.

A patient interface may include a dual chamber cushion assembly having a nasal chamber and an oral chamber. The nasal chamber may be arranged to deliver pressurized breathable gas to a patients nasal passages, and the oral chamber may be arranged to deliver pressurized breathable gas to the patients oral passages. The nasal chamber may be pressurized to a different level than an oral chamber to promote nasal breathing. An air passage may fluidly connect the nasal chamber and the oral chamber so that pressurized breathable gas may flow from the nasal chamber to the oral chamber.

A nebuliser for nebulising liquid droplets, including: a housing; at least one piezoelectric substrate (2) accommodated within the housing and having a transducer surface (2a) upon which is located at least one electroacoustic transducer (48) for generating acoustic wave energy within the at least one piezoelectric substrate (2), and an opposing non-transducer surface (2b); a liquid supply system for supplying a liquid to at least one of the transducer and non-transducer surfaces, the liquid supply system including a reservoir (3) for accommodating the liquid, and at least one relatively rigid supply conduit in contact with the at least one piezoelectric substrate (2) for supplying the liquid from the reservoir (3) to the at least one piezoelectric substrate (2); and a sensor for detecting a volume of liquid on the at least one piezoelectric substrate (2).

Method and device for controlling the quantity of liquid contained in a cartridge for an aerosol generating device, wherein the cartridge has a container and a liquid contained in the container and wherein, according to which is measured the quantity of liquid contained in the cartridge; and compared the quantity of liquid with a reference quantity of liquid.

Methods and systems for monitoring fluid levels and electrolyte levels used in a dialysis machine. A receptacle, configured to receive a container, comprises a plurality of curved side panels and a base to form a cylindrical shaped cavity for receiving a container. Each panel includes a conductive material on its inner surface and, optionally, a shielding on its outer surface. An electronics component housed within, or near, the receptacle drives the capacitive process and interprets generated data to determine fluid levels and compositions. An alternate receptacle includes one or two coils wrapped about the container and uses induction to determine fluid level.

A filling aid device for filling a reservoir. The device includes a cover portion comprising a septum window; a slider beam comprising a septum cover; and a first filling aid tab attached to the slider beam, the first filling aid tab in slidable relation to the cover from a first position to a second position, wherein when the filling aid device is in an unlocked position, the septum cover is located below the septum window, wherein when the first filling aid tab is moved from the first position to the second position, the septum cover is moved from below the septum window, and the filling aid device is in the locked position.

An assistance device for the use with a product dispensing device includes an engaging unit to the dispensing device, a locking unit for locking the dispensing device and configured to prevent or permit dispensing of the product, and a measurement unit for measuring a quantity of the product dispensed by the dispensing device. The locking unit remains unlocked for a predetermined period of time starting from a predetermined activation of the assistance device and then locks automatically at the end of the predetermined period. The locking unit locks automatically when a quantity of the product dispensed during the predetermined period reaches or exceeds a predetermined threshold.

IV stand assemblies are provided that include a base, a stand, a platform and a motorized pole assembly having a housing, a pole and a drive. The drive moves the pole to extend and retract the pole relative to the housing. A weight measurement assembly measures weight of a fluid within a fluid container hanging from the IV stand assembly. IV stand assemblies with a pulley/belt assembly and methods of operating IV assemblies are also provided.
