The IV infusion set further comprises a compliance element configured to attenuate pressure variations of medical fluid the infusion line, and a resistance element configured to reflect pressure waves moving along the infusion line. The sensor is arranged on the infusion line at a position downstream from the resistance element with respect to a direction of fluid flow along the infusion line from the medical fluid source towards the patient access. The infusion line may include a main infusion line and/or one or more auxiliary infusion lines connected to a main infusion line.

Aspects of the present disclosure provide methods, apparatuses, and systems for closed-loop sleep protection and/or sleep regulation. According to an aspect, sleep disturbing noises are predicted and a biosignal parameter is measured to dynamically mask predicted disturbing environmental noises in the sleeping environment with active attenuation. Environmental noises in a sleeping environment of a subject are detected, input, or predicted based on historical data of the sleeping environment collected over a period of time. The biosignal parameter is used to determine sleep physiology of a subject. Based on the environmental noises in the sleeping environment and the determined sleep physiology, the noises are predicted to be disturbing or non-disturbing noises. For predicted disturbing noises, one or more actions are taken to regulate sleep and avoid sleep disruption by using sound masking prior to or concurrently with the occurrence of the predicted disturbing noises.

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.

Systems and methods are provided remotely controlling a medical device. In some embodiments, systems and methods are also provided for remote medical monitoring. This includes, for example, emergency/panic notifications/functions, medical event recording, compliance monitoring, sleep timer and environmental controls, two-way communication, and other functions such as, for example, emergency telephony/communication in various forms. In other embodiments, systems and methods for managing a remote control of a medical device are provided. This includes, for example, two-way communication for assisting in locating the remote, power management including sleep mode and wireless charging, and master remote/key functionality. The remote can be handheld or wearable and may include, for example, audio, visual, haptic, input, communication, and sensor (including biosensor) functionality and outputs. In this manner, the remote control can not only control the medical device, but also provides the user with extended functionality for emergency and non-emergency communication and tasks.

A super enriched personal oxygen concentrator system that discards argon as waste, including a personal oxygen concentrator operatively attached to a first bed for absorbing nitrogen and second bed for absorbing oxygen, and an argon waste outlet operatively attached to the first and second beds for eliminating argon from the system. A method of using the system of the present invention, by absorbing nitrogen from compressed air from a POC with a first bed, absorbing oxygen with a second bed, discarding unabsorbed argon from the compressed air as waste, desorbing enriched oxygen product, and providing a 99% oxygen product. A fluid supply warning and communication system, wherein a primary fluid reservoir is connected to the personal oxygen concentrator system. A method of using the fluid supply warning and communication system.

An injection system is described that receives, from one or more sensors, a first group of one or more signals indicating a current volume of injection fluid dispensed from a fluid reservoir at a first time. The injection system determines, based on the first group of one or more signals, that a difference between a dispensed volume limit and the current volume of the injection fluid dispensed from the fluid reservoir at the first time is less than a necessary volume of fluid required to complete both a systolic injection phase and a diastolic injection phase. The injection system further, responsive to determining that the difference is less than the necessary volume of fluid required to complete both the systolic injection phase and the diastolic injection phase, controls the injection system to refrain from performing each of the systolic injection phase and the diastolic injection phase.

A method includes applying, via a respiratory therapy system, initial therapy settings for a user during a first sleep session in which the user uses the respiratory therapy system. First physiological data, which is received from one or more sensors, is generated during the first sleep session. Modified therapy settings are applied, via the respiratory therapy system, during a second sleep session of the user. Second physiological data is received from the one or more sensors. The second physiological data is generated by the one or more sensors during the second sleep session. A set of sleep-related parameters is determined based on changes between the first physiological data and the second physiological data. One or more of a recommended therapy or recommended therapy settings is determined based on the set of sleep-related parameters.

A device is described for delivering a therapeutic vibration to a body. The device may include at least two motors in a housing with unbalanced masses coupled to their axles, such that vibration of the masses causes the two motors and housing to vibrate at a beat frequency 80. The motors and housing may be coupled to the body via a platform which places the motors and housings at or near a resonant structure in the body, creating a coupled oscillation between the platform and the body. The vibration may be based on the input signal, such that the system applies the vibration based on the input signal to the user, wherein the signal may be an audio or video signal. The system may be configured to measure and manipulate the flow of cerebral spinal fluid.
