The invention relates to a method for mixing at least two fluids using an externally mixing nozzle for medical purposes, which has at least two outlet channels (10, 20) and at least two inlet openings (13, 23) with different or identical cross-sections, wherein two fluids with different volumetric flows and/or different viscosity are sprayed, and wherein the ratio of the cross-sections of the inlet channels (13, 23) and/or the outlet channels (10, 20) corresponds to the ratio of the volumetric flows so that the fluids flow with substantially identical flow speeds through the outlet channels (10, 20) and/or the inlet openings (13, 23). The invention furthermore relates to an externally mixing nozzle, a medical instrument and a medical device for spraying substances, in particular biological material.

An apparatus for coating pharmaceutical particles such as drug dosage forms or pellets is provided which includes a drum assembly mounted for rotation about a cylindrical axis of the drum and which includes an outer drum section and an inner perforated drum section mounted concentrically on an interior of the outer drum section such that an annular chamber is formed between the perforated inner drum section and the outer drum section. Two or more baffle plates are attached between an outer surface of the inner perforated drum and an inner surface of the outer drum which are configured to act as baffles to restrain or regulate the flow of air which define two or more compartments depending on the number of baffle plates. One end of the drum assembly includes an end plate with a central aperture for use in loading pellets into the drum and provide access to coating constituents that are pumped into the drum interior during the coating process. An air distribution plate is attached at the other end of the drum and has air flow passageways and is interfaced with an air introduction plate having air inlet and outlet passageways. As the drum rotates the air flow passageways in the distribution plate alternately come into flow communication with the air inlet and outlet passageways in the air introduction plate thereby providing a flow path of air into the perforate inner drum and out of the drum assembly.

Described is an apparatus for preparing baby formula using a liquid concentrate solution. The apparatus includes a housing with a cavity for receiving and holding a container liquid concentrate solution. A motor is attached with the housing for forcing liquid concentrate solution from the container and into a mixing chamber. A pump and a water tank are also included. A spray head is attached with the housing. The spray head includes a plurality of spray jets in fluid connection with the pump for receiving water from the water tank and dispensing water from the spray jets into the mixing chamber. Finally, the mixing chamber receives the liquid concentrate solution and water, such that when the water and the liquid concentrate solution are introduced into the mixing chamber, the water and liquid concentrate solution mix into a baby formula and are dispensed from an outlet in the mixing chamber.

A mixing apparatus includes a first and a second feeding tube, a first and a second atomizing/refining dose control device, and a reaction chamber. The first and second feeding tubes are arranged in a multi-sleeves manner. The first and second atomizing/refining dose control devices are respectively disposed on terminal ends of the first and second feeding tubes. The reaction chamber accommodates the first and second feeding tubes and the first and second atomizing/refining dose control devices and has a liquid dose mixing wall. The first and second feeding tubes respectively receive a first and a second liquid dose. The first and second atomizing/refining dose control devices respectively atomize or refine the first and second liquid doses and spray the atomized or refined first and second liquid doses on a surface of the liquid dose mixing wall, so as to mix the first and second liquid doses.

A nozzle assembly includes a mixing channel and an aerator. The mixing channel has upstream and downstream ends defining a flow direction through the mixing channel and includes a housing wall and a mixer. The housing wall defines a flow passage and includes an inlet portion and a tip orifice. The inlet portion disposed at the upstream end and configured to receive a first material and a second material. The tip orifice is disposed at the downstream end and is configured to emit a plural component material from the mixing channel. The mixer is disposed within the mixing channel and is configured to mix the first material and the second material into the plural component material. The aerator is configured to flow nucleation air to a location downstream of an upstream end of the mixer and into a flow of the plural component material.
