Embodiments of the invention are directed to an outdoor paint sprayer having an air pump chamber separate from a refillable and/or replaceable paint chamber. In some aspects, the outdoor paint sprayer is configured to dispense a liquid paint with minimal dilution, such that a paint having an original concentration may be aspirated and dispersed by the outdoor paint sprayer without requiring additional manipulation of the paint outside of the sprayer. In some aspects, the outdoor paint sprayer includes one or more nozzle features and/or tips that produce a desired spraying application. In further aspects, additional features for emulating a particular marking effect may be incorporated with and/or coupled to the sprayer for application.

A system for dispensing a biocompatible reactive formulation includes a first chamber containing a first fluid having a first reactive component, a second chamber containing a second fluid having a second reactive component, and a third chamber containing a third fluid. A spray tip assembly is configured for spraying a final mixture of the first, second and third fluids. The spray tip assembly has a spray tip housing, a mixing element disposed within the spray tip housing, a mixing chamber located between the mixing element and an inner surface of the spray tip housing. The mixing element has a proximal end adjacent the proximal end of the spray tip housing and a distal end adjacent the distal end of the spray tip housing, a third fluid inlet opening at the proximal end of the mixing element, and one or more third fluid exit openings formed in the outer surface of the mixing element that are in fluid communication with the third fluid inlet opening and that extend laterally to the outer surface of the mixing element for being in fluid communication with the mixing chamber. A fluid connector is secured to the proximal end of the spray tip housing and opposes the proximal end of the mixing element. The fluid connector has first and second fluid channels in fluid communication with the mixing chamber, and a third fluid channel in fluid communication with the third fluid inlet opening of the mixing element. A pump assembly is coupled with the first, second and third chambers for simultaneously forcing the first, second and third fluids to flow through the first, second and third fluid channels of the fluid connector and into the proximal end of the spray tip housing.

Systems and methods for humidifying ventilator delivered breathing gases are disclosed. These systems and methods utilize a hollow cone atomizer (e.g., a pressure swirl atomizer) and/or a heating element associated with a heating circuit and/or a heating tube. In some aspect, the systems and methods utilize received flow, temperature, and/or humidity information to determine an amount of water to add to breathing gases to reach a desired humidity of the breathing gases delivered to the patient. In further aspects, the humidification system can serve as a nebulization system for delivering nebulized medicine.

An atomizing nozzle structured particularly for nasal therapy. Preferred embodiments include a 2-piece atomizing nozzle structured to couple with luer-locking structure carried by a syringe. Such an atomizing nozzle includes a nasal stopper and a stem. A preferred nasal stopper includes a distal tip sized for insertion into a nostril of a human child, with a proximal shield portion being structured to resist over-insertion of a discharge orifice into the nostril. A nasal stopper desirably provides a centering function to urge the discharge orifice away from a nasal wall. One operable stem is structured to couple with the stopper and desirably carries unitary thread structure at a proximal end. A second operable stem is structured as a unitary part of the nasal stopper and also desirably carries unitary thread structure at a proximal end. Certain embodiments may also include spacer structure configured to reduce a dead volume inside the atomizing nozzle. Other embodiments may also include spacer structure configured to reduce dead volume inside a syringe that is coupled to the atomizing nozzle.

The two-piece nozzle for an aerosol dispenser, has (i) an outer piece (12, 22) provided with a tubular wall (121, 221) open on one side and closed on the other by a front wall (122, 222), forming a cavity, the front wall being provided at its center with an outlet opening (123, 223), the outer piece having a certain symmetry about an axis of symmetry (A) and (ii) inner piece (11, 21) separate from the dispenser for which the nozzle is intended, the inner piece (11, 21) being dimensioned to penetrate into the cavity of the outer piece while being retained therein, the inner piece having a front face (111, 211) facing the front wall (122, 222) of the outer piece and a lateral face following the front face. Channels (112, 125, 224, 225) are made in the cavity of the outer piece (12, 22) and/or on the surface of the inner piece, which channels open into a turbulence chamber (127, 227) in communication with the outlet opening (123, 223), the outlet opening (123, 223) being placed in the flow path of the product flow downstream of the turbulence chamber. The channels are divided into lateral channels (112, 224) in the lateral face of the inner piece (11, 21) and/or in the inner face of the tubular wall of the outer piece (12, 22), and into converging channels (125, 225) in the front wall (122, 222) of the outer piece or in the front face (111, 211) of the inner piece.

A spray device includes a first spray tip having a first fluid pathway defining a first flow area, and a second spray tip includes a second fluid pathway that defines a second flow area that is larger than the first flow area of the first spray tip. The first and second spray tips are side-by-side and spaced from one another at a distal end of the spray device. When a first fluid having a volumetric flow rate is introduced into the first spray tip and a second fluid having the same volumetric flow rate is introduced into the second spray tip, the first fluid will flow through the first fluid pathway at a greater velocity than the second fluid will flow through the second fluid pathway.

The present disclosure discloses and describes a vapocoolant dispenser. Specifically, the dispenser comprises a housing and container of vapocoolant, the dispenser configured to receive a sterilizable dose of high energy radiation and to provide a sterile, hermetically sealed vapocoolant dispenser.

A spray device includes a bottle portion, a sleeve, and an engine The engine includes a spring that when compressed pressurizes a chamber containing a dispensable amount of fluid from the bottle portion. The sleeve and the engine are configured to be torquable onto the bottle without compressing the spring. Rotation of the sleeve relative to the bottle by a user pressurizes a chamber containing fluid from the bottle. Auditory and/or tactile feedback is provided to the user during rotation of the sleeve thereby allowing the user to select an amount of the fluid to be dispensed. The engine includes a main spring that when compressed pressurizes a chamber containing a dispensable amount of fluid from the bottle. The spring is enclosed between a cup and a cap, which have been fused together.
