A method and a system of alerting and/or monitoring patient with sleep disorder includes: a detector for detecting a change in a first parameter, a storage device, a control unit for deciding if the change meets a set criteria, and if the change meets the set criteria, saving the first parameter and/or time in the storage device, a feedback unit for adjusting the set criteria according to sleep behavior of the patient, and an alarm device for sending an alarm, wherein the first parameter includes sound, motion, heart rate, blood pressure, breathing frequency, magnitude and/or frequency of movement, muscle activity, brain activity, eye movements, heart rhythm, heart rate variability, blood oxygen levels, breathing pattern, and/or body position.

Systems, methods, and devices for humidifying a breathing gas are presented. The system includes a source of pressurized breathing gas, a vapor transfer unit external to the source of pressurized breathing gas, a first gas tube connecting the source of pressurized breathing gas to the gas inlet of the vapor transfer unit and having a first length, a liquid supply having a heater that heats liquid, a first liquid tube coupling the liquid supply to the liquid inlet of the vapor transfer unit, and a second gas tube having a second length and connecting the gas outlet to a patient interface. The first length is greater than the second length. The vapor transfer unit includes a gas passage, a liquid passage, and a membrane separating the gas passage and the liquid passage. The membrane is positioned to transfer vapor from the liquid passage to the gas passage.

A device for motion sickness reduction. The device operates by providing haptic feedback using transducers that convert electrical signals to a tactile sensation such as pressure, vibration, electrical stimulation, temperature, or airflow. The transducers are located at different locations on the body of a user, and actively change their operation to indicate a direction of motion or rotation to the user through haptic (tactile) feedback. This tactile feedback can be used to reduce motion sickness. In an embodiment, the feedback is improved by deducting motion associated with the user's visual frame of reference from motion associated with the user's vestibular frame of reference.

A catheter system may include a catheter adapter, which may include a distal end, a proximal end, and a lumen extending through the distal end and the proximal end. The catheter system may include a connector coupled to the proximal end of the catheter adapter. The connector may include a T-connector. The catheter system may include a connector support device, which may be wedge-shaped to support the connector at an insertion angle.

An on-body drug delivery device having a housing carried by a substrate. The substrate includes one or more cut-outs and/or one or more perforations to allow the substrate to better conform to the patient's body.

A virtual reality game- and biosignal sensor-based VOR assessment and rehabilitation apparatus includes: a biosignal sensing unit which senses and notifies of head movement and eye movement of a patient using an eye tracker and an inertial measurement unit (IMU) sensor attached or installed to a head-mounted display device; a VOR function assessment unit which configures and provides a game for VOR function assessment; a patient-personalization control unit which determines, on the basis of the VOR gain of the patient, the types and order of rehabilitation games, and a rehabilitation level; and a rehabilitation game providing unit which configures and provides games for at least one among smooth pursuit, saccades, VOR rehabilitation exercise, amplified VOR rehabilitation exercise, and suppressive VOR rehabilitation exercise, and determines the difficulty levels of the games on the basis of the rehabilitation level.

According to an aspect there is provided a method for automatic maintenance of a dialysis system. The dialysis system includes a plurality of filter sections where each filter section includes a blood flow channel, a dialysate flow channel, and a membrane separating the blood flow channel from the dialysate flow channel and having a plurality of pores through which substances are exchanged between a blood flow in the blood flow channel and a dialysate flow in the dialysate flow channel. The method includes determining, for each filter section of the plurality of filter sections, whether a maintenance criterion is fulfilled. The method also includes triggering a maintenance event for a filter section of the plurality of filter sections for which the maintenance criterion is fulfilled. The method also includes executing the maintenance event and optionally administering a thrombolytic agent to the blood flow channel of the filter section.

Ambulatory medical devices that provide therapy to a subject, such as blood glucose control, are disclosed. Disclosed systems and devices can transmit a request to modify blood glucose control therapy delivered to a subject. The request can be transmitted via a voice-activated control system, the ambulatory medicament pump can include a medicament reservoir, a pump controller, a wireless data interface, and/or other elements. The device can receive an indication that the request to modify therapy is approved and, in response to the indication that the request to modify the blood glucose control therapy is approved, instruct the pump controller to modify the blood glucose control therapy delivered to the subject.

The disclosure provides systems and methods for neuromodulation using a housing that at least partially contains a stimulator assembly, wherein the stimulator assembly is configured to generate vibration by mechanical oscillation and/or using a sound wave; and wherein the vibration generated by the stimulator assembly is configured to therapeutically treat the subject by stimulating one or more nerves when the housing is placed in proximity to or on a skin surface of a subject.

Systems and methods for performing Direct Sodium Removal (DSR) therapy are provided in which an implantable device includes a pump coupled to an inlet catheter designed for placement in a patient's peritoneal cavity, an outlet catheter designed to be coupled to the patient's bladder, and is operably coupled to an analyte sensor, the pump programmed to transfer and/or cease transfer of fluid from the patient's peritoneal cavity to the patient's bladder for voiding responsive to a level of analyte detected by the analyte sensor. In addition, the system may include a processor that computes an amount of analyte transferred per pumping session.
