The present technology relates to the field of medical monitoring, and, in particular, to non-contact detecting and monitoring of patient breathing. Systems, methods, and computer readable media are described for calculating a change in depth of a region of interest (ROI) on a patient. In some embodiments, the systems, methods, and/or computer readable media can identify steep changes in depths. For example, the systems, methods, and/or computer readable media can identify large, inaccurate changes in depths that can occur at edge regions of a patient. In these and other embodiments, the systems, methods, and/or computer readable media can adjust the identified steep changes in depth before determining one or more patient respiratory parameters.

A medical therapy device may include a user interface (6100) such as a combined touchscreen/dial user interface, for input of operation parameters. The user interface may include a dial and a touchscreen to display a subset of a list of items. Each item may represent a parameter of the medical device. The displayed subset may include a pre-selected item that may provide a pre-selection indication for a particular item. Rotation of the dial may move the pre-selection indication so it may change between items on the displayed subset. In response to a swipe gesture on the touchscreen, the displayed subset may scroll through the list. Also, the swipe gesture may cause pushing of the pre-selection indication against a boundary of the display such as in the direction of the swipe gesture such that the item associated with the pre-selection indication remains part of the displayed subset.

In an example, a ventilator includes a first container and a second container in fluidic communication with each other via a liquid. The second container includes a second container space surrounded by the second container and a second liquid surface. A hydrostatic pressure in the second container space results from a pressure differential defined by a difference between the first liquid surface elevation in the first container and the second liquid surface elevation. The second container space increases in size with an increase in the breathing gas supplied from a gas supply line to the second container space. An inhalation line is configured to open to permit a flow of the breathing gas from an inhalation inlet in the second container space to an inhalation outlet outside of the liquid and outside of the second container and coupled to a patient, causing the second container space to decrease in size.

An integrated respiratory pressure therapy device and humidifier for pressurising and humidifying breathable air to treat a respiratory disorder in a patient, includes a blower configured to pressurise the breathable air; a water reservoir configured to hold a volume of water to be used for humidification of the breathable air, the water reservoir comprising a water reservoir base, a water reservoir lid connected to the water reservoir base, and a compliant portion. The compliant portion is constructed from an elastomeric material and configured to seal between the water reservoir base and the water reservoir lid. A water reservoir dock forms a cavity configured to partially receive the water reservoir. The water reservoir lid includes a protrusion and the water reservoir dock includes a recess configured to releasably engage one another to secure the water reservoir to the water reservoir dock.

A resuscitation device is disclosed that includes a pump having a cylinder with a gas inlet and a gas outlet, a piston to travel in the cylinder, and a valve. The valve is configured to allow gas to be displaced into the cylinder through the gas inlet during a first stroke direction and second stroke direction of the piston in the cylinder, and for allowing gas to be displaced through the gas outlet during an opposite of the first stroke direction and second stroke direction of the piston in the cylinder; a motor, selected from one of a stepper motor, a feedback motor, a stepper motor with feedback, and a linear motor, connected to the piston to move the piston in the cylinder; and a patient interface in fluid connection with the pump to receive gas via the gas outlet and to deliver the gas to a patient.

A water reservoir for an apparatus for humidifying a flow of air for delivery to an entrance of the airways of a patient for respiratory therapy includes a reservoir base configured to hold a volume of water, a reservoir lid comprising an inlet and an outlet, a hinge joint to pivotally couple the reservoir lid to the reservoir base for pivotal movement between an open position and a closed position, wherein the reservoir lid and the reservoir base cooperate to form a sealed internal volume at the closed position, and a rotation stop, wherein the rotation stop is arranged between the reservoir lid and the reservoir base at the open position, and wherein the rotation stop is configured and arranged to disconnect the reservoir lid from the reservoir base at the hinge joint when the reservoir lid is over-pivoted beyond the open position.

An integrated respiratory pressure therapy device and humidifier for pressurising and humidifying breathable air to treat a respiratory disorder in a patient, includes a blower configured to pressurise the breathable air; a water reservoir configured to hold a volume of water to be used for humidification of the breathable air, the water reservoir comprising a water reservoir base, a water reservoir lid connected to the water reservoir base, and a compliant portion. The compliant portion is constructed from an elastomeric material and configured to seal between the water reservoir base and the water reservoir lid. A water reservoir dock forms a cavity configured to partially receive the water reservoir. The water reservoir lid includes a protrusion and the water reservoir dock includes a recess configured to releasably engage one another to secure the water reservoir to the water reservoir dock.

The present disclosure provides techniques for a ventilator system with a removable airway. A ventilator system may include a removable airway and a base unit. The removable airway may include an air inlet port, a patient inhalation port, an air exhaust port, and a patient exhalation port. The base unit may include two pinch valves. In some cases, the removable airway does not comprise any openings other than the air inlet port, the air exhaust port, the patient inhalation port, and the patient exhalation port. In some cases, the removable airway is configured such that air inside the removable airway does not contact any part of the base unit. In some cases, the removable airway is configured such that air that enters the patient exhalation port is contained within the removable airway along a contiguous path and at no point does the contiguous path contact the base unit.

A therapeutic device for treating one or more conditions associated with a user's nasal cavities, sinuses, and/or ear canals includes a housing having an opening, an acoustic vibrator within the housing that is operable to provide an acoustic vibration to the user, a fan within the housing that is operable to provide a pressure to the user and a power supply that provides power to the acoustic vibrator and the fan. A mask is connected to the housing at the opening and includes a nasal interface appliable around the nose of the user, a nasal chamber in which the user's nostrils are located and an aperture through which the fan delivers the pressure.

One or more sensors are configured for detection of characteristics of moving objects and living subjects for human identification or authentication. One or more processors, such as in a system of sensors or that control a sensor, may be configured to process signals from the one or more sensors to identify a person. The processing may include evaluating features from the signals such as breathing rate, respiration depth, degree of movement and heart rate etc. The sensors may be radio frequency non-contact sensors with automated detection control to change detection control parameters based on the identification of living beings, such as to avoid sensor interference.
