The present invention provides for the integration of drug dispersion methods into a drug or medicine delivery system. The drug dispersion methods used include shear (e.g., air across a drug, with or without a gas assist), capillary flow or a venturi effect, mechanical means such as spinning, vibration, or impaction, and turbulence (e.g., using mesh screens, or restrictions in the air path). These methods of drug dispersion allow for all of the drug in the system to be released, allowing control of the dosage size. These methods also provide for drug metering, fluidization, entrainment, deaggragation and deagglomeration. The present invention also provides for the integration of a drug sealing system into the device. The drug sealing system provides a way of blocking the migration of drug from one area of the package to another. The drug seal system can also provide a method of tightly containing the drug until the package is opened, of directing airflow through the package and of managing and containing the drug during the package/device manufacturing process.

A method to manipulate respiration with odor dispensing includes dispensing a dose of odor toward a user from a distance of 10 cm-3 m from the user and controllably dissipating the odor in the vicinity of the dispensing at pre-defined period after the dispensing. The method is optionally configured to reduce snoring and/or apnea events while the user is sleeping.

A motion pillow according to an embodiment of the present disclosure includes a body, a motion system, a connector, and a valve. The body includes a plurality of airbags provided therein. The motion system includes a pump allowing air to enter and exit the airbags, a sensor measuring air pressures of the airbags, a sound receiver receiving sound from around the body, and a controller controlling operating mode in accordance with measurements of the sensor. The connector connects the airbags and the motion system. The valve opens and closes the connector. When at least one airbag among the plurality of airbags is pressed and air is introduced to the sensor through the connector, the controller is configured to switch the operating mode from standby mode to active mode. Significantly improved convenience and satisfaction of sleep are provided to users.

A check valve can include a pressure actuator or an electromagnetic actuator. The check valve includes a valve inlet, a valve outlet, and flap disposed between the valve inlet and the valve outlet. The pressure actuator in fluid communication with the valve inlet. The check valve has an open state and a closed state. The check valve is configured to allow an input gas to flow from the valve inlet to the valve outlet when the check valve is in the open state. The check valve is configured to preclude the input gas from flowing from the valve inlet to the valve outlet when the check valve is in the closed state. Upon actuation of the pressure actuator or the electromagnetic actuator, the flap moves away from the valve inlet to allow the inlet gas to move from the valve inlet to the valve outlet.

The present disclosure describes a system and method for maintaining oxygen purity in portable oxygen concentrators, even with asymmetric generation of oxygen enriched gas volumes from different sieve beds of the concentration system. The present system and method compensate for asymmetric oxygen enriched gas generation using asymmetric delivery of purge volumes. Purge valves are used to deliver the asymmetric purge gas volumes, enables the system to maintain oxygen purity without additional power consumption, even when a portable oxygen concentrator does not include a product tank. The present system and method are configured such that asymmetry in enriched oxygen generation can be monitored and the asymmetric purge gas compensation can be applied independently from other control mechanisms of a portable oxygen concentrator.

An intelligent baby caring method and arrangement helps to recognize and maintain emotional interaction between mother and her baby and to improve the baby's life rhythm and calm and soothe him/her automatically when needed and help him/her to fall asleep and to wake up at the most convenient time and way. The aim is to help the mother with her baby to find optimal life and care rhythm. The invention is focused on a platform (101) with many sensors, sensor sheet (120), a transducer to produce acoustic and mechanical vibrations (14) and an airflow blower (132). Sensors are also fixed to the mother (10) and in the care room (198). A sleep/activity graph of the baby and sleep/emotion graph of the mother are measured and tracked with multimodal sensors and an artificial intelligence unit (200) processes audio, motion and airflow actions given to the baby from the platform to help the baby to move from an improper to optimal sleep/activity level.

An intubation device utilizes a steerable endotracheal tube guide, a novel mechanism to automatically position an endotracheal tube at the laryngeal opening, and a novel system for soft tissue retraction to improve visualization of the laryngeal opening. An ETT is positioned within an overtube having proximal and distal ends and a flexible tip. The distal end houses a feeder mechanism for displacing the endotracheal tube through the overtube. A hood includes a stem, base, and expandable body, and may be affixed to the overtube's distal end. The ETT-containing overtube is precisely positioned at a laryngeal opening via positioning effects of body expansion, activation of a tip director, and/or flexible tip articulation. Unhindered visualization of the laryngeal opening is achieved by the expandable body, pushing the soft tissue outwardly and extensibly. An actuation module controls the feeder mechanism as well as the flexible tip to position flexible tip and endotracheal tube.

The invention discloses an aromatherapy humidifier, which includes a base, a shell and a cover, which are superimposed sequentially. An atomizing container is arranged on the base. A water storage tank is arranged on the atomizing container. The atomizing container and the water storage tank are contained in the shell. The water storage tank supplies water for the atomizing container and is provided with a mist channel communicated with the atomizing container. The atomizing container is provided with an atomizing assembly for atomizing water into mist and an aromatherapy assembly for volatilizing essential oil. The cover is covered on the shell and the water storage tank, the cover is provided with a spray port communicated with the mist channel and an water inlet communicated with the water storage tank, the mist and the volatilizing essential oil float through the mist channel and the spray port to humidify air.

A device, called expandable spacer, for improving the efficacy of drug delivery in metered dose inhalers is described. The device has a body made of flexible (might be expandable) material. It can shrink in size when it is not in use and can go back to its normal shape and size when it is used. The device further comprises a valve (can be one way valve) that helps the drug to be maintained inside the spacer's cavity and opens during inhalation and closes during exhalation.

An add-on device and method for an Endo-Tracheal Tube (ETT), the add-on device including a lengthy body having a major arc-shaped cross section sized and shaped to tightly fit over an ETT, at least one longitudinal cavity passing along the lengthy body, including a distal suction cavity ending with a suction inlet at a distal end of the lengthy body; and a distal suction outlet channel extending from a proximal end of the lengthy body, the channel is a continuous extension of the distal suction cavity and configured to provide suction to the distal suction cavity. The add-on device senses moisture at a distal end of the add-on device, and in case of detection of excessive wetness, provides suction to the distal end of the device through a cavity passing along the device, the suction is provided via a suction outlet channel extending from a proximal end of the device.
