The present disclosure presents infant soothing devices which provide timed, color, and intensity controlled light and sound projections to assist in sleep therapy. The devices may be part of a smart nursery which has a number of electronically connected devices which communicate with a central electronic application to gather information and provide operation instructions to the devices. The smart nursery may be connected to a larger network to provide feedback and controllability outside of the nursery.

A system may include an external device and an inhaler. The external device may include a processor, a communication circuit, and memory. The inhaler may include a mouthpiece, medicament, a mechanical dose counter, and an electronics module comprising a processor and a communication circuit. The electronics module may record a dosing event when the inhaler is actuated, such as when the mouthpiece cover is opened, and send a signal indicating the dosing event to the external device. The external device may receive a mechanical dose reading of the mechanical dose counter, determine an electronic dose reading based on the signal indicating the dosing event, determine that a discrepancy between the mechanical dose reading and the electronic dose reading exceeds a threshold, and notify the user of the discrepancy, for example, by providing a notification to the user by way of a mobile application residing on the external device.

A tank for accumulating oxygen enriched air from an oxygen concentration device is disclosed. The oxygen concentration device includes a canister including a nitrogen-adsorbent material. A compressor is coupled to the canister. The compressor compresses air for the canister to produce oxygen enriched air in a swing adsorption process. The tank includes a closed container for collecting oxygen enriched air produced in the canister. An inlet is coupled to the container. An outlet in the container allows a patient to inhale the collected oxygen enriched air. An adsorbent material within the container adsorbs oxygen enriched air added to the tank from the canister.

An acoustic dose meter is provided comprising a housing, and a cylindrical seat for staging a pressurized medicine canister. The housing includes at least one compartment for housing electronics and passageways for connecting electronics for power and data communication. A microprocessor including a transient memory containing machine instruction is also included. Additionally, a power source connected to the microprocessor, a power switch connected to the microprocessor and the power source for booting the microprocessor are added. At least one visual display device connected to the microprocessor for displaying available doses is provided. A first set of acoustic sensors connected to the microprocessor and adapted as acoustic sound generators and a second set of acoustic sensors connected to the microprocessor and adapted as acoustic soundwave recorders are implemented to detect and analyze frequencies enabling determining of dosing count availability.

Systems and methods for assessing compliance with position therapy. In an embodiment, position therapy is provided to a user while the user is wearing a position therapy device. The position therapy comprises, by the device, collecting positional data, determining positions of the user over a time period based on the positional data, and, when it is determined that the user is in a target position, providing feedback to the user to influence the user to change to a non-target position. In addition, the device stores a duration of use in its memory. The duration of use indicates a duration that the user has used the wearable position therapy device in each of one or more positions. An assessment of the user's compliance with the position therapy is then provided based, at least in part, on the duration of use.

Methods and systems for monitoring the status and usage of a metered dose inhaler (MDI) and communicating status, usage, and guidance information to a user of the MDI and to a mobile computing device are presented herein. An IMD includes a dosage dispense detection device, an accelerometer, and a visual transducer, an audio transducer, a haptic transducer, or any combination thereof. The dosage dispense detection device detects when a user applies a compressive force across the IMD. The accelerometer measures a shaking of the IMD by a user before self-administering a dose. The IMD determines whether the medicine is adequately shaken by the user, and if so, communicates an indication to the user that the pressurized canister of medicine is ready for dosage. In another aspect, the IMD communicates a sequence of indications that mark each transition of a dosage regimen plan to self-administer a dosage of medicine.

Aspects of the present disclosure provide a smart relaxation mask configured to output a stimulus and collect biometric information while the stimulus is output to determine if the subject is paying attention to the stimulus. If the subject is not focused on the stimulus, the mask adjusts at least one of an audio, visual, or haptic output. The stimulus is adjusted in an effort to shift the subject's attention to the stimulus and away from racing thoughts.

A valve assembly including a housing having a base and an outer shell, which forms a proximal cavity and a distal cavity joined by a canal; an inner housing configured for longitudinal movement within the distal cavity; a seal positioned within the distal cavity that together with the longitudinal movement of the inner housing regulates the flow of fluid through the valve assembly; and one or more selected from the group consisting of the base notched with one or more notches and the inner housing having one or more through slots aligned to permit access to the one or more notches, the seal being a reversibly deformable sealing pin, and a torque limiter mechanism configured to resist the longitudinal movement of the inner housing distally until a sufficient radial force is applied.

A system and methods are described for improving the management of ischemic cardiac tissue during acute coronary syndromes. The system combines a catheter-based sub-system which allows for simultaneous balloon dilation of a coronary artery and infusion of a carefully controlled perfusate during percutaneous coronary intervention. The system allows for modulation of levels of oxygen at the time of percutaneous intervention. In addition, catheters and systems are provided for administration of fluids with modified oxygen content during an intervention that incorporate upstream flow control members to compartmentalize the perfusion of the target coronary artery and the remainder of the heart.

A method for generating a flow profile of an inhalation device is described. The method comprises the step of measuring acoustic emissions induced by inhalation flow through the inhalation device. The method further comprises the step of detecting peak frequencies in the measured acoustic emissions and generating a flow profile based on the detected peak frequencies. A corresponding device is also described.
