An intrapulmonary aerosolizer (10) comprises an aerosolizer (11) attached to a pressure generator (30) for delivery of liquid as an aerosol, and which can be positioned in close proximity to a patient's lungs by being inserted into a patient's trachea directly or into an endotracheal tube or bronchoscope positioned within a patient's trachea.

An RV toilet (10) having a seat section (12) that includes a bowl (16) with a bottom discharge opening. The toilet (10) also includes a source of flush water (22) for rinsing the bowl and removing waste through the discharge opening into a waste storage tank (14). A pump (32) provides the flush water through a nozzle (52) which directs the flush water into the bowl. A check valve (56) is associated with discharge nozzle (52) to prevent flush water from inadvertently leaking into the bowl (16). The check valve (56) is capable of being used with either a manually actuated pump or a power assisted pump and reduces the force required by the pump to maintain the valve open than to initially open it.

A mains pressure valve which comprises a main chamber (12) having an inlet chamber (11) for fluid and a discharge chamber (14) for fluid; a piston (17) located in the main chamber (12) which is movable into and out of sealing engagement with the outlet of the main chamber (12) and which defines above it an upper portion (40) of the main chamber (12); a port (35) in the upper portion (40) which permits fluid to flow therethrough; and actuation control (42) associated with the port to regulate the flow of fluid through the port. Upon actuation fluid in the upper portion (40) drains through port (35) allowing piston (17) to rise and mains pressure fluid passes from inlet chamber (11) through main chamber (12) and out discharge chamber (14). Fluid bleeds via flow valve (21) and (22) into upper portion (40) and as port (35) is closed piston (17) closes the valve after a predetermined period.

摘要:
Valve autobloquante, notamment pour récipient aérosol, comportant une tige (2) montée coulissante dans un corps (3) de valve divisée en deux chambres (A) et (B) par un joint (6) qui peut coulisser sur la tige (2) entre une butée (21) et une position permettant la communication entre les chambres (A) et (B) sous l'influence de la pression dans le récipient, lorsque ladite pression exerce sur le joint (6) une force antagoniste supérieure à celle exercée par un ressort (11) sur ce joint (6).
摘要:
The valve comprises a closure member (20) adapted for attachment to the container (21), said closure member defining an aperture therein. A hollow grommet (22) of flexible material having a flange portion (27) to one side of the closure member and a tubular portion (28) extends through the aperture in the closure member. A valve rod (23) having at one end a flange (30) engaged with the underside of the flange of the grommet and a hollow stem portion (31) extending through the grommet to protrude therefrom such that upon tilting of the valve rod relative to the closure member the flange of the valve rod parts from the underside of the flange of the grommet to uncover a radial hole in the stem portion through which pressurised fluid can pass into the hollow stem portion for dispensing. A gallery (24) is provided in between the grommet and flange of the valve rod and arranged to admit pressurizing gas through the closure member into the container when the valve rod is tilted.
摘要:
A valve comprising a base solid (1) providing a valve chamber (2) and a valve stem (3) slidably fitted and upwardly biased by a spring (12) in the chamber. An inlet (9) is made on the bottom of the chamber thereby permitting injection of aerosol from the associated aerosol tank. The valve stem provides a longitudinal channel (4) and an outlet (5) communicating the channel with the valve chamber, and a valve head (11) fixed to the bottom end. A valve ring (7) fitted at the upper side of the chamber in air-tight fashion shutting the outlet all the time. Whereby on depression of the valve stem, the valve ring is yieldingly bent for opening the outlet of the valve stem, thereby allowing a predetermined amount of aerosol to flow out of the valve chamber and eject from the longitudinal channel of the valve stem while shutting the inlet on the bottom of the chamber with the valve head of the valve stem.
摘要:
A spraying device, particularly a brush-like apparatus for the cleaning and/or massage of the body, particularly a tooth-brush (1) with at least one nozzle body (10'), may be coupled to a hollow handle connectable by a pipe to a water tap. The nozzle body (10') is preferably provided as a fluid oscillator free of moving parts. The hollow handle may receive inside a metering capsule a hardly water soluble active agent rod. To this effect, the handle comprises a removable oblong cap of which the front end may be coupled in such a way that it prevents the torsion with a tube (5) at the cleaning brush. The cap is further provided with a hand-actuable water stop member which may be displaced in an open position by hand in the direction opposite to a spring force and/or to the antagonist water pressure. The water stop member is conveniently a multistage slide valve piston (58) with conical terminal portion (72). The bristles (4) of the body cleaning apparatus are appropriately arranged on a bristle plate (3) which is secured to a bristle fixing portion (2) that may be readily changed by means of a snap connection, the bristle plate (3) and the bristle fixing portion (2) forming together with the tube (5) and a well-like recess receiving the nozzle body (10') the tooth-brush (1), for example.
