Electronic device for producing an aerosol for inhalation by a person
11517685 · 2022-12-06 · ·

An electronic device for producing an aerosol for inhalation by a person includes a mouthpiece located at one of opposite longitudinal ends of the device; a liquid container; a transducer that, when actuated, causes a liquid from the container to be aerosolized such that the aerosol may be inhaled from the device by a person through the mouthpiece; and circuitry and a power supply for actuating the transducer. The mouthpiece, the container, and the transducer are located in-line along a longitudinal axis of a housing of the device extending between the opposite longitudinal ends of the device. The container is located between and separates the transducer and the mouthpiece. The container and the transducer are contained within a cartridge that is insertable into and removable from the housing of the device. The container and the transducer are replaceable by the person when the liquid in the container is depleted.

BREAST PUMP DEVICE

A breast pump device (1) comprises an expression kit (2), a vacuum unit (3), and a conduit (5) for establishing an air path between an air outlet (27) of the expression kit (2) and an air inlet (35) of the vacuum unit (3). The expression kit (2) is equipped with a barrier portion (26) for preventing milk leakage from the expression kit (2) towards the hose (5) and the vacuum unit (3). In case some droplets of milk enter the barrier portion (26) and/or drawn through the barrier portion (26) by an ongoing pumping action, aspects of the behavior of the motor (32) for driving the pump (31) are influenced, and the insight that this happens is used for terminating operation of the motor (32) as soon as a too large deviation of one or more operational characteristics of the motor (32) with respect to a reference is found.

Gas recirculation system and method

Gas recirculation systems for use in endoscopic surgical procedures including a gas recirculation pump are disclosed. The gas recirculation pump may work in conjunction with an insufflator used to inflate a patient's peritoneal cavity during surgery. The gas recirculation system may recirculate a high flow rate of gas from and to the patient while filtering particulate matter out of the gas and while maintaining an adequate moisture content in the gas. The gas recirculation pump may include a disposable pump cartridge releasably connected to a pump motor. A controller may detect a fault or safety condition in the gas recirculation system based on the load placed on the pump motor.
