A device, system, and method for vaporizing substances in a pod or a cartridge, utilized for inhalation by a user. The device includes components to measure the content and dosage pods or cartridges containing substances, among other features. The device includes a graphical user interface that may be integrated with the device or implemented through a mobile device, which allows the user to transmit user data to a remote database and/or healthcare provider for personal and clinical data collection. The user data can be used for enhancing personal treatment or clinical research.

An adapter for selectively providing fluid to a device from one of multiple fluid sources has a body with a first inlet for connecting a first one of the multiple fluid sources to the device and a second inlet for connecting a second one of the multiple fluid sources to the device. The adapter also includes a handle that is movably coupled to the body and includes an access control element. The handle is configured to secure the body to a device when the adapter is in either of a first position or a second position that is rotated relative to the first configuration. The access control element obstructs access to the second inlet when the adapter is secured to the device in the first position and the access control element obstructs access to the first inlet when the adapter is secured to the device in the second position.

A system for measuring the vital parameters of low care patients is described. The system includes a connecting element for a nasal cannula or breathing mask for providing a fluidic connection with the patient and a flow and/or pressure sensor in fluidic connection with the nasal cannula or breathing mask, for sensing, when the nasal cannula or breathing mask is connected to the system, at least a negative pressure signal. The system also includes a processor configured for deriving, directly based on said at least a negative pressure signal, information related to the breathing cycle, and an output means configured for outputting at least one vital parameter of the patient, the outputting comprising outputting information related to the breathing cycle.

Systems and methods for detecting extubation of an endotracheal tube (ETT) are described. Extubation of the ETT can be identified by comparing to a threshold, a difference between a determined first volume of breathing gas during a first inspiratory period to a determined second volume of breathing gas during a second inspiratory period. If the difference exceeds the threshold, an alarm can be activated indicating extubation. Extubation detection may also be based on a difference between inspiratory pressures during separate inspiratory periods. Partial extubation and full extubation may also be discerned. Further, extubation of an ETT may be detected without the use of an exhalation flow sensor.

Breathing assistance apparatus includes a gases supply unit adapted to, in use, deliver a stream of pressurised gases from an outlet. The gases supply unit is adapted to vary the pressure of the stream of pressurised gases. A supply path includes a flexible self-supporting gases transportation pathway having a first end connected to the outlet so that the gases transportation pathway receives the stream of gases and conveys the gases to a patient. A patient interface is connected to the second end of the gases transportation pathway receives a stream of gases. At least one sensor measures at least one information parameter of the supply path. A control system associated with the gases supply unit receives the information parameter. The control system contains reference data, and compares the received data to reference data, and determines a supply path based on the comparison.

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 relates to a supplementary device for a manually operable injection device. The device has a body and a mating unit configured to releasably mount the body to the injection device in a specific position relative to an outside surface of the injection device.

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.

The invention includes an alarm assembly configured to engage a tube that is capable of extending into a patient. The alarm assembly comprises alarm circuitry, a wound dressing configured to releasably attach to the patient that includes at least one actuator, and a sensor holder. The sensor holder is configured to be releasably coupled to the tube and includes at least one sensor. The at least one sensor is configured to transmit a signal to the alarm circuitry when the at least one actuator actuates the at least one sensor, and the alarm circuitry is configured to produce an alert in response to receiving the signal. The invention also includes a method of detecting a tube dislodging from a patient, as well as a kit comprising a tube, alarm circuitry, a wound dressing, and a sensor holder.

A flow control apparatus adapted to receive a feeding set includes a housing capable of receiving at least a portion of the feeding set. A pumping device is supported by the housing and positioned to contact the feeding set when the feeding set is received by the housing so the pumping device acts on the feeding set to produce fluid flow in the feeding set for delivery of fluid to a subject. An ultrasonic sensor is supported by the housing and arranged with respect to the pumping device to produce a sensor signal indicative of a viscosity of the fluid delivered through the feeding set. A control circuit is in communication with the ultrasonic sensor for receiving the sensor signal from the sensor indicative of the viscosity of the fluid and in communication with the pumping device to control operation thereof.
