An apparatus (100) to maintain an environment over an anterior surface of a patient eye can include an enclosure (110) sized and shaped to be seated about the patient eye to form a cavity (112) within the enclosure. The enclosure can be configured to contain a fluid other than ambient air in contact with the patient eye. The apparatus can include a fluid regulator (1209) in communication with the enclosure, where the fluid regulator can be configured to regulate the composition of the fluid contained within the enclosure.

A respiratory treatment apparatus provides respiratory treatment with improved power management control to permit more efficient power consumption and power supply units, such as battery powered operation. In one embodiment, power management prioritizes the flow generator (104) over other accessories such as the heating elements (111, 135) of a humidifier (112) and/or a delivery tube. The flow generator may control operations of the heating elements as a function of a detected respiratory cycle. For example, the timing of operation of the heating elements may be interleaved with the portion of an inspiratory phase of the respiratory cycle to permit the flow generator to operate during a peak power operation without a power drain or with a lower power drain from these components. Operations of distinct sets of components of the system (e.g., different heating elements) may also be interleaved to prevent simultaneous peak power operations.

Devices disclosed herein relate to humidification systems for making humidified ventilator air. The humidification system provides an elongated air path that increases both the surface area and time for air-water interaction, and thus increases efficiency of humidification. The humidification system also enables even distribution of heat and inhibition of bacterial growth within the system, thus improves comfort and safety for patients receiving respiratory therapy. Device disclosed herein also relates to tubing for delivering humidified ventilator air. The tubing includes an air passage and a heat blanket that envelops and warms up the air passage. The tubing thus prevents or decreases water condensation and loss of humidity of humidified air.

A compact wearable inhaler, vaporizer and/or atomizer is addressed by the wearable multifunctional inhaler, vaporizer and smartwatch of the present invention. In the best mode, the invention includes a housing with a chamber having at least port; a lid adapted to engage the housing and open the chamber in a first position and close the chamber in a second position; a source of inhalant mounted within the housing for sourcing inhalant into the chamber via the ports; and an mechanism coupled to the housing for wearing the device. The source of inhalant may be a vaporizer, pipe, inhaler or atomizer.

An aerosol delivery system has a nebulizer and a humidifier providing a gas flow to the nebulizer. A controller varies humidity level of the gas flow to the nebulizer so that if the nebulizer is not operating it has about 100% humidity and it is operating the value is less to allow for the humidification effect of the nebulizer. The control may be achieved by dynamically varying proportions of flow through a dry branch and a humidification branch.

A respiratory pressure therapy (RPT) device is disclosed for treatment of respiratory-related disorders. The RPT device includes a pressure generator, a pneumatic block, a chassis and a device outlet for delivering a supply of flow of gas to a patient interface. The RPT device also comprises a humidifier including a water reservoir.

Introduced are methods and systems for an adjustable bed device configured to: gather biological signals associated with multiple users, such as heart rate, breathing rate, or temperature; analyze the gathered human biological signals; and heat or cool a bed based on the analysis.

A pressure support system includes a pressure generating device, an airflow path, and a control system. The control system is structured to determine a first measurement indicative of an amount of water vapor in the airflow path or an amount of condensation in the airflow path and generate a number of control signals structured to control an environmental control device structured to control an environmental parameter in an environment including the pressure support system, wherein the control signals are generated based on at least the first measurement and are configured to cause the environmental control device to adjust the environmental parameter in a manner that will reduce a degree or a likelihood of rainout in the airflow path, and transmit the control signals to the environmental control device so that it may be controlled to reduce the degree or likelihood of rainout.

A breathing assistance apparatus that comprises a housing with inner and outer walls and an upper surface, wherein the walls and upper surface are integrally formed as a single part to avoid seams or joins between the walls to reduce the risk of damage to electronics within the apparatus as a result of liquid leaks. Also disclosed is a control system for a heating element of a humidifier which provides a secondary or back up protection mechanism to disable power to the heating element if a first electronic protection circuit does not cause the first switching member to disable power to the heating element.

A respiratory pressure therapy (RPT) device is disclosed for treatment of respiratory-related disorders. The RPT device includes a pressure generator, a pneumatic block, a chassis and a device outlet for delivering a supply of flow of gas to a patient interface. The RPT device also comprises an integrated humidifier including a water reservoir. An RPT device is also disclosed that includes a wireless data communication interface integrated with the housing and configured to connect to another device or a network.
