Embodiments provide an oxygen supply device having multiple operational states including a first state and a second state. In the first state, the oxygen supply device is controllable to a local control instruction such that the oxygen supply device can be operated by a user physically located within a proximity of the oxygen supply device. In the second state, the oxygen supply device is only controllable to a remote-control instruction such that the oxygen supply device can be operated by a user remote to the oxygen supply device. For example, the user can be located in an office remote to a location of the oxygen supply device, which, for example, may be placed at a patient’s home. In the second state, the user is enabled to control the oxygen supply device from a device associated with the user in the remote location.

Provided is a filtering facepiece respirator. The respirator includes a mask body having an anterior side portion, a posterior side portion, a middle portion, a first side portion, a second side portion, a top side portion, a bottom side portion and outer edge portions. The respirator further includes a primary port positioned at the anterior middle portion of the mask body and a detachable primary port adapter which is positioned over and engages the primary port. The respirator may further include an oxygen port and oxygen port adapter and a luer port and luer port adapter.

A catheter includes a tubular body to be inserted into a living body. The tubular body has a lumen that is held in fluid communication with an injection port defined in a distal end of the tubular body and a suction port near a proximal end of the tubular body, and the suction port is closed when the injection port is open, and the injection port is closed when the suction port is open.

A method and a system for determining the amount of oxygen required by a user with respiratory problems are disclosed. First data about several users with respiratory problems is stored in a database. The method a) collects second data from a monitored user while (s)he is performing a test at a first location; b) computes a user’s behavioral model executing a first algorithm on the first and second data; c) collects, every period of time t1, third data of the user while (s)he is performing an activity at a second location; d) adjusts, every period of time t2, the computed user’s behavioral model using the first algorithm, providing a customized user’s behavioral model as a result; and e) computes an estimator of the quantity of oxygen to be delivered to the user by executing a second algorithm on the customized user’s behavioral model.

A system includes an electronic circuit, a memory, and a control system. The electronic circuit is coupled to a conduit. The conduit may be configured to deliver pressurized air. A portion of the electronic circuit has a first electrical property that is configured to change based at least in part on movement of the portion of the electronic circuit. The memory stores machine-readable instructions. The control system includes one or more processors configured to execute the machine-readable instructions. Data associated with the first electrical property of the electronic circuit is received. The received data is analyzed. Based at least in part on the analysis, it is determined that the first electrical property of the electronic circuit has changed. Responsive to the determination that the first electrical property of the electronic circuit has changed, it is determined that the conduit is moving or has moved.

A ventilation device for providing a gas mixture for a user including a compressor to output compressed air; a valve to receive the compressed air and medical gas and selectively output a gas flow of at least one of the medical gas and the compressed air; a patient interface configured to provide the output gas flow of the valve; and a controller to control the valve to deliver substantially only the medical gas to the patient interface during a first portion of the inspiratory period and deliver substantially only the compressed air to the patient interface during a second portion of the inspiratory period.

A bioelectronic device houses therapeutic cells and is configured to be implanted in a host. The device includes an electrochemical cell that produces oxygen gas from water when a voltage is applied. The oxygen gas produced by the electrochemical cell is stored in a gas diffusion chamber in the device. The therapeutic cells in a cell housing chamber in the device receive oxygen gas from the gas diffusion chamber to help keep the cells alive and functioning when the device is implanted in a low oxygen environment. The device receives power wirelessly.

A device for improving cognitive and functional capabilities by means of hypoxic and hyperoxic gas mixtures. An air splitter (5) separates oxygen and nitrogen and feeds these gases to a mixer (4), whose mixing rate is determined by feed back from a bio feedback regulator and an oximeter. The oximeter is connected to a finger piece sensor or pulse meter, and/or an ear-piece sensor for receiving inpute from a patient. The gas mixer feeds an adjusted oxygen and nitrogen mixture to the patient by way of a mouthpiece connected to the mixer.
