The invention also relates to a method for monitoring the dispensing of a complete dose during the activation of a product dispensing device (12), by means of such an assistance device (10).

The invention relates to the field of inhalation devices for liquids. In particular, the invention relates to a nebulizing nozzle to be used in such an inhalation device, as well as a method for fabrication of such a nozzle. A nozzle for an inhalation device for nebulizing a liquid into a respirable aerosol has a nozzle body (1) which has a front end (1B) and which comprises at least two ejection channels (2, 2′), each channel (2, 2′) having an channel exit (2A, 2A′), wherein the ejection channels (2, 2′) are arranged such as to eject liquid along respective ejection trajectories which intersect with one another at a collision point. The nozzle is characterized in that at least one recess (3) is provided at the front end (1B) in which the channel exits (2A, 2A′) are positioned. Disclosed is also a method for the fabrication of a nozzle body as defined above, use of such a nozzle in an inhalation device for nebulizing a liquid, and an inhalation device for nebulizing a liquid into a respirable aerosol, comprising such a nozzle.

The present disclosure provides systems and methods for delivering a gel to a surface. In one embodiment, the system may have a first vessel with a first low viscosity aqueous solution comprising a binder/crosslinking agent; and a second vessel with a second low viscosity aqueous solution comprising a gelling component. The separate first and second low viscosity aqueous solutions are sprayed onto a surface where the solutions mix forming a gel.

The present disclosure provides systems and methods for disrupting the outer membrane of an oocyst in solution and delivering the solution to an animal. The system includes a vessel containing unbroken oocysts in solution, an oocyst processing chamber, and a delivery outlet. The unbroken oocysts are moved from the vessel through the processing chamber and a portion of the oocyst membranes are disrupted releasing sporocysts, the resulting solution is moved from the processing chamber into the delivery outlet where the solution is delivered to an animal. Methods of vaccination, including vaccination against an Eimeria infection, are also provided.

A system for delivery of a fluid to an animal is provided in the present disclosure. The system includes a reservoir to hold a volume of fluid, delivery outlet, recirculating loop, and valve in fluid communication between the reservoir and delivery outlet, the valve having an inlet to receive fluid from the reservoir, a first outlet in fluid communication with the delivery outlet, and a second outlet in fluid communication with a return conduit to the reservoir. The system further includes control means for opening and closing the first and second valve outlets, and a pump to pump fluid from the reservoir to the valve and through the reservoir return conduit to the reservoir. When the control means opens the first outlet, the fluid flows from the reservoir to the delivery outlet. When the control means opens the second valve outlet, the fluid flows through the return conduit to the reservoir.

Apparatus and methods for delivering humidified breathing gas to a patient are provided. The apparatus includes a humidification system configured to deliver humidified breathing gas to a patient. The humidification system includes a vapor transfer unit and a base unit. The vapor transfer unit includes a liquid passage, a breathing gas passage, and a vapor transfer device positioned to transfer vapor to the breathing gas passage from the liquid passage. The base unit includes a base unit that releasably engages the vapor transfer unit to enable reuse of the base unit and selective disposal of the vapor transfer unit. The liquid passage is not coupled to the base unit for liquid flow therebetween when the vapor transfer unit is received by the base unit.

A discharge head for discharging liquid as an atomized spray jet and as a non-atomized liquid stream or as individual droplets. The discharge head fastening fastens to a base unit and has a liquid outlet through which liquid is discharged from a reservoir into the atmosphere, and a liquid inlet through which liquid is conducted out of the reservoir to the liquid outlet. An internal part is arranged inside an outlet channel, and a spray opening is provided on the internal part. The internal part and the outlet channel are relatively displaceable so that in a first position a bypass duct is produced between an internal wall of the outlet channel and an outer face of the internal part, the flow resistance thereof being lower than the spray duct, and in a second position is partially closed wherein the flow resistance of the bypass duct is greater than the spray duct.

A system with a nebulizer as well as a container with a fluid and an indicator device for such a nebulizer are proposed. A check scheme is used for indicating the number of containers already used with the nebulizer or which still can be used with the nebulizer. The indicator device indicates the number of uses performed or still possible with the current container. The indicator device is adapted to let stepwise appear a color sequence and/or replacement symbol when approaching a predetermined number of uses with the container. Further, the indicator device can show markings in braille.
