A hydrodynamically cooled and filtered smoking apparatus is provided having a housing, an inlet pipe, a stirring mechanism, and a flow deflecting body. The housing having at least one wall portion providing a chamber configured to contain a fluid for circulation therein. The inlet pipe has an inlet configured to draw in smoke from a source and an outlet provided within the chamber beneath a top surface of the contained fluid configured to deliver the smoke into the chamber for entrainment within the fluid. The stirring mechanism is provided in the housing and is driven to induce cyclonic circulation of the fluid and the smoke in the chamber. The flow deflecting body has a suction surface with at least one aperture provided in the suction surface and communicating with the inlet pipe. The suction surface is oriented in the fluid to generate hydrodynamic force to draw smoke into the fluid and aerate the fluid by entraining the smoke in the fluid as bubbles. A method is also provided.

A nebulizer unit for use in a nebulizer includes an aerosol generator, a housing, a medication reservoir and a cap. The aerosol generator having a supply side and a discharge side, which is retained between a sealing ring at the supply side and a retaining structure at the discharge side. The housing encloses the aerosol generator, the sealing ring and the retaining structure. The medication reservoir is integrated into the housing and includes an interior hollow volume, into which the medication liquid is introduced. The cap seals the reservoir, and includes a closure pin that subdivides the interior space of the reservoir into a first partial volume another partial volume. The liquid-tight closure being formed by the complementary partial surfaces. At least one of the two complementary partial surfaces of the closure pin and of the inner space of the reservoir having a rubber or silicone covering.

A dry powder delivery device may be configured to provide micronized dry powder particles to airways of a user. The device may include a cylindrical container delimiting a chamber containing at least one magnetically-responsive object, a motor external to said chamber, a magnet external to the chamber and rotatably coupled with the motor, and an outflow member configured to direct airflow to a user. The magnetically-responsive object may be coated with micronized dry powder particles, and the motor may be operable to rotate the magnet about an axis. Rotation of the magnet creates a magnetic field that causes the magnetically-responsive object to move in response to the magnetic field and collide with a side wall of the container to deaggregate the dry powder particles and aerosolize the dry powder in the chamber.

A vaporizer, including: an eye ring; a ring comprising stainless iron; a first lock block; a first end support; a thermal insulation cotton; a stainless-steel tube; a second end support; a support cylinder; a second lock block; a magnet; a thermistor; a mounting seat; a spring support; a spring; a pneumatic switch; a silicone sleeve sleeving the pneumatic switch; annular sleeve; a coil support; an inductor; a printed circuit board; a first end cover; a first cover plate covering the first end cover; a button; a circuit board; two electrical contacts; a battery; a housing; a second end cover; a second cover plate covering the second end cover. The thermal insulation cotton is sheathed on the stainless-steel tube. The first end support and the second end support are disposed on two ends of the stainless-steel tube, respectively. The first lock block is disposed on the first end support.

The invention relates to an inhaler spacer (1) comprising an inlet (2) for connection to an inhaler and an outlet (4) through which a user can inhale. The inhaler spacer (1) comprises a duct (6) extending between the inlet (2) and the outlet (4). The duct (6) is defined by a wall (8) which extends around a first axis (10) and comprises a diffuser portion (12) extending along the first axis away from the inlet. The wall (8) of the duct (6) in at least apart of the diffuser portion curves outwardly away from the first axis with increasing distance away from the inlet such that the cross sectional area of the diffuser portion perpendicular to the first axis increases with increased distance from the inlet along the first axis.

Systems for dense phase transport of frozen and other particles to the respiratory system include a particle source, a delivery chamber for metering boluses of the particles from the source, and a transfer tube for fluidized transport of the particles to a patient interface. A controller may be provided to adjust the rate and amount of the bolus deliver to a patient to control core body temperature and for other purposes.

Disclosed herein is a sprayer which may include, but is not limited to, a main body with a neck an inner cross section area of which gradually decreases; an air blowing module installed for air in the inside of the main body to be discharged to the outside; a liquid medicine container installed at a lower side of the main body and having air holes at a lid of the liquid medicine container; a nozzle cap having a minimum diameter part at an inner intermediate portion and assembled to the neck of the main body; a nozzle a rear end of which is open and connected to an end of a liquid supply pipe; and a rib which is configured to support in such a way that a central axis of the nozzle can position on a central axis of the nozzle.

Liquid accumulators and methods for reducing pulsations of a liquid flow are disclosed. A liquid delivery system comprises a pump configured to drive liquid to a pipe. The pipe is configured to transmit a liquid flow. A liquid accumulator is fluidically connected to the pipe. The liquid accumulator comprises a chamber containing the liquid and a vapor column and a power source configured to input energy to the chamber to generate vapor from the liquid to form the vapor column. The vapor column constitutes a gas spring to reduce pulsations of the liquid flow in the pipe. The spring rate of the gas spring can be adjusted by changing the input energy level from the power source to the chamber.
