An atomiser, in particular an inhaler, for atomising a liquid active agent to form an aerosol, having, inter alia, an active agent reservoir, an atomiser nozzle and a pump arrangement, wherein a suction side of the pump arrangement leads into the active agent reservoir and a pressure side of the pump arrangement leads into the atomiser nozzle, and wherein the pump arrangement has a plunger that can be adjusted in a cylinder in the axial direction of the cylinder. A corresponding method is also described.

Introduced here is a self-contained face mask system with an automated liquid-droplet dispensing mechanism (ADM) for humidification. The enclosure of the self-contained mask system can be comprised of one or more layers of breathable fabric adapted to flexibly conform to the face of a user when worn to form a cavity that is adjacent the nostrils and mouth. The ADM of the face mask system can be comprised of a reservoir in which liquid is stored, a respiratory cycle detector, a timer and controller, and a droplet dispenser that controllably dispenses droplets of the liquid from the reservoir into the cavity for inhalation by the user. The ADM can be contained entirely within the face mask enclosure or supported on the surface of the face mask enclosure such that the self-contained mask system, when worn by a user, can be supported entirely by the head and neck of the user.

The present invention is a fluid dispensing apparatus, and method of use, e.g. for mouthwash and medicine, for dispensing a sterile liquid in single doses to prevent bacterial growth from un-used portions pored back into the apparatus. The apparatus has a hollow flexible cap enclosure surrounding a one-way valve inside of a bladder and a push rubber surface for liquid release. When the cap is removed, both the container body and the cap remain sealed from exposure to contaminates. Liquid is first dispensed from the container by inverting the container until a quantity of sterile liquid collects in the cap. The container is then positioned in an upright position and the fluid filled cap is removed from the container. The cap is then inverted again and a pushbutton pressed to dispense sterile liquid from a cap spray nozzle without requiring the user's lips to touch the cap.

Methods and apparatus for assembling dispensing devices and/or for dispensing a medicament include a sealing element fixed in a receiving space of the dispensing device with a specific assembly parameter. A plurality of sealing elements is produced in batches, and all sealing elements of a batch are fixed with the same assembly parameter.

Disclosed is a ratchet mechanism having ratchet ring and a chassis. The ratchet ring is rotatable about an axis relative to the chassis, with a general direction of rotation determined by teeth of the ratchet mechanism. The ratchet ring has a first set of teeth arranged regularly around the ratchet ring and protruding in a first axial direction from the ratchet ring and a second set of teeth arranged regularly around the ratchet ring and protruding in a second opposite axial direction from the ratchet ring. The chassis has a third set of teeth arranged regularly and protruding in the second axial direction and generally opposed to the first set of teeth, and a fourth set of teeth arranged regularly and protruding in the first axial direction and generally opposed to the second set of teeth.

The present disclosure provides a heating assembly and an atomization device. The atomization device includes an oil guiding member and a heating member. The oil guiding member has a through hole cutting through the oil guiding member. The through hole is configured to guide atomized gas generated on the oil guiding member out of the oil guiding member. The oil guiding member includes a connecting part. The connecting part is located in the through hole. The connecting part spans the through hole along a radial direction of the through hole. The heating member is embedded in one end of the oil guiding member. At least part of the heating member is located on the connecting part. The heating member is used for heating the oil guiding member, so that the liquid to be atomized is atomized on an end face of the oil guiding member close to the heating member.

Embodiments of the invention are directed to flush syringe assemblies comprising an integrated contamination-prevention device integrated with device connector flushing positioned so that the practitioner cannot forget to apply disinfectant. The flush syringe assemblies comprise a barrel with an elongate plunger rod disposed therein and a cap comprising a passageway. The plunger rod includes a stopper of which at least a portion can be embedded in the passageway of the cap to form a plug in the cap. Methods of flushing a vascular access device (VAD) while providing a flush syringe assembly described herein are also disclosed.

The present invention relates to an electronic atomizing device, an atomizer and a suction nozzle assembly thereof. The suction nozzle assembly includes a fixing base, a suction nozzle, and a connecting member. The suction nozzle includes a first end and a second end away from the first end. One end of the connecting member is mounted to the suction nozzle, another end is mounted to the fixing base, such that the suction nozzle is disposed on the fixing base via the first end, and is capable of rotating relative to the fixing base. The suction nozzle can rotate relative to a power supply assembly in the electronic atomizing device, therefore an operation switch of the power supply assembly can be rotated from an initial position to an operation position convenient for an operation.
