New medical circuit components and methods for forming such components are disclosed. These components include microstructures for humidification and/or condensate management. The disclosed microstructures can be incorporated into a variety of components, including tubes (e.g., inspiratory breathing tubes and expiratory breathing tubes and other tubing between various elements of a breathing circuit, such as ventilators, humidifiers, filters, water traps, sample lines, connectors, gas analyzers, and the like), Y-connectors, catheter mounts, humidifiers, and patient interfaces (e.g., masks for covering the nose and face, nasal masks, cannulas, nasal pillows, etc.), floats, probes, and sensors in a variety of medical circuits.

An apparatus for treating a respiratory disorder in a patient includes a blower configured to generate a supply of pressurized respiratory air to the patient via an air delivery tube leading to a patient interface; a dock with a heater plate; and a reservoir comprising a conductive portion configured to thermally engage the heater plate.

A ventilator system includes a ventilation device, and is configured to operate in a passive mode configured to transmit ventilation data in response to requests from a ventilation management system, or an active mode configured to automatically transmit ventilation data as the data becomes available. The system receives ventilation system data associated with operation of the ventilation device, modifies one or more operating parameters of the ventilation device based on the received ventilation system data, receives ventilator data associated with the ventilator device, determines an alarm associated with the ventilator device or a patient based on the received ventilator data and, responsive to determining the alarm, sends the alarm to a beginning of a transmission queue for transmitting the ventilation data to the ventilation management system, wherein the alarm is communicated over the network prior to other ventilation data in the transmission queue.

The disclosed device serves for artificial respiration and has a blower connected to a control. The blower is held by a supporting part, which assumes the task of decoupling and other functions. The blower and the supporting part are arranged in a blower box. Both the control and the blower box are arranged in a housing. The control is connected to at least one indicating device and also to at least one operating element.

An apparatus for delivering a flow of gas has a housing, a cover, and a magnetic coupling system arranged to magnetically couple the cover to the housing. Each of the housing and cover having complementary locating features, the locating features being adapted to locate and align the cover and the apparatus relative to each other to allow for the magnetic coupling. The apparatus also has a handle movably connected to the housing and is movable from a first position to a second position. The housing and the handle comprise complementary interlock features arranged to engage with each other when upward force is applied to the handle in the second position, and the interlock features are disengaged from each other when the handle is in the second position but upward force is not applied to the handle.

An apparatus for humidifying a flow of pressurised, breathable air includes varying a first pressure of the flow of breathable gas to vary a level of thermal engagement between the conductive portion of the reservoir and the heater plate, varying a height of the variable portion varies a level of thermal engagement between the conductive portion of the reservoir and the heater plate, use of a humidifier reservoir base component with a maximum water capacity substantially equal to the predetermined maximum volume of water of the humidifier reservoir or the use of intersecting inlet and outlet axes.

Embodiments of the present disclosure provide systems and methods for monitoring a patient to produce a signal representing a blood oxygen concentration. The signal may be analyzed to determine the presence of one or more sleep apnea events, and an integral of the signal may be calculated if the signal is outside of a set range or threshold. A practitioner may choose to be informed of the presence of sleep apnea events if the blood oxygen concentration is less then a preset limit, if an upper limit has been reached for an integral representing the severity of the oxygen deprivation over time, or anytime sleep apnea events may be present in the signal.

A facemask includes a facemask body, a plurality of electrical contacts and a control circuit. The facemask body has an end including an opening and a skin contact perimeter extending along a periphery of the opening, with the skin contact perimeter configured to sealingly engage with a user's face. Each electrical contact is disposed at a respective region of the skin contact perimeter, and each electrical contact is configured to sense when the respective region of the skin contact perimeter is sealingly engaged with a user's face. The control circuit is disposed on the facemask body, and the control circuit is configured to receive a signal from each electrical contact when the respective region of the skin contact perimeter is sealingly engaged with a user's face and to initiate output of an audible stimulus and/or a visual stimulus in response to receiving a concurrent signal from all of the plurality of electrical contacts.

A droplet delivery device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The droplet delivery device includes a housing, a reservoir, and ejector mechanism, and at least one differential pressure sensor. The droplet delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The droplet delivery device is then actuated to generate a stream of droplets having an average ejected droplet diameter within the respirable size range, e.g, less than about 5 μm, so as to target the pulmonary system of the user.
