A valve structure for treating a patient suffering from obstructive sleep apnea is provided. The valve structure is connected to an air flow generator and is connected to a mask that covers at least the nostrils of a patient. The valve structure includes an inlet pressure port attached to the air flow generator and an expiration valve that includes an expiratory membrane, a primary seat and a secondary seat. During inspiration, the expiratory membrane forms a seal with the primary seat, and during expiration, the expiratory membrane forms a seal with the secondary seat.

Systems and methods for inducing natural sleep in a subject is provided. In some aspects, the method includes inducing a first sleep state; monitoring a first plurality of characteristics of a brain of the subject to verify the subject is in the first sleep state; inducing a second sleep state after the subject has been in the first sleep state for a predetermined amount of time; and monitoring a second plurality of characteristics of the brain of the subject to verify the subject is in the second sleep state.

The subject matter is a patient supporting device for supporting a patient during a medical treatment, in particular a dialysis treatment, and a treatment apparatus with such a patient supporting device, and a corresponding method for controlling and/or regulating a medical treatment device, in particular a dialysis device, using such a patient supporting device.

A personal vapor inhaling unit including a microprocessor, memory, and a wireless communication interface is disclosed. An application may control aspects of the personal vapor via the wireless interface. An electronic flameless vapor inhaler unit that may simulate a cigarette has a cavity that receives a cartridge in the distal end of the inhaler unit. The cartridge brings a substance to be vaporized in contact with a wick. When the unit is activated, and the user provides suction, the substance to be vaporized is drawn out of the cartridge, through the wick, and is atomized by the wick into a cavity containing a heating element. The heating element vaporizes the atomized substance. The vapors then continue to be pulled by the user through a mouthpiece and mouthpiece cover where they may be inhaled.

A physiologic sensor module includes at least one wearable sensor that is configured for wearing on a human body part and for measuring at least one biological signal. The module further includes at least one controller communicatively coupled to the wearable sensor and configured to receive the biological signal from the wearable sensor. The controller is further configured to process the biological signal in real-time, extract one or more clinical features from the biological signal, and based on the clinical features, determine detection of anaphylaxis.

An extracorporeal blood treatment apparatus is provided comprising a filtration unit connected to a blood circuit and to a dialysate circuit, a preparation device for preparing and regulating the composition of the dialysis fluid; a control unit is configured for receiving a desired sodium mass transport at the end of the treatment session and for setting the sodium concentration value for the dialysis fluid in the dialysis supply line at a set point to achieve the desired sodium mass transport at the end of the treatment session.

A wound monitoring and/or therapy system can include a substantially stretchable substrate supporting a plurality of electronic components, including sensors, and a plurality of electronic connections that connect at least some of the electronic components. The electronic components can also include a circuit board supporting at least one controller configured to control at least some of the sensors, the circuit board configured to operate without failure when the substrate is flexed as a result of strain. A calibration track can be positioned on the substrate and connected to a monitoring circuit configured to measure a change in resistance of the calibration track indicative of resistance change of at least some of the plurality of electronic connections. The system can include a controller with a circuit board supporting a plurality of electrical components and an antenna configured to communicate with the substrate, the antenna at least partially enclosing the circuit board.

A system for measuring cardiovascular data includes an elongate member having a channel, a first expandable member carried by the elongate member and movable between a collapsed state and an expanded state by adjustment initiated externally of a subject, a first sensor disposed on a surface of the elongate member, second and third sensors disposed on a surface of the first expandable, a first optical sensor located at a first location in relation to the distal end of the elongate member and configured for obtaining photoplethsmographic data, and wherein the first expandable member in its expanded state is configured to interface with the subject's larynx for delivery of at least oxygen gas into the respiratory system of the subject, and the second and third sensors are configured to contact tissue in proximity to the larynx when the first expandable member is in its expanded state.

Sleep management apparatus including a wearable device having one or more physiological sensors operably engaged with a body of a user. One or more processors can be communicatively coupled with the wearable device having a memory storing instructions when executed operable to: detect one or more indicators of a bedtime; measure one or more physiological indicators predictive of a ready for sleep condition of the user; suggest, when one or more of the one or more physiological indicators exceed a predetermined threshold, a sleep preparation exercise; and track an effectiveness of the sleep preparation exercise.
