A medical device is provided for irrigation of a patient wound site. The device contains a tube having a proximal portion adapted to receive an irrigation solution, a distal portion having a nozzle and an intermediate portion for transporting the solution. The tube has a barrel portion that may be manipulated by a user to position the device relative to the wound site. A distinctive nozzle has a body formed with a distally leading channel presenting a semispherical first spatial conformation and a proximally leading opening formed in the body presenting a second spatial conformation intersecting the semispherical terminus. This geometry, derived from principles of flow mechanics discussed herein, defines what will be described as an “effective diameter” of the nozzle. An assembly and system utilizing the device am also disclosed. The invention utilizes a fluid-isolating durable peristaltic pump for a continuous flow of irrigation solution, along with a single use tube set that embodies the device.

A gas-liquid two-phase flow atomizing nozzle includes a nozzle core, an outer sleeve, and an atomizing body. An inner cavity of the nozzle core consists of an inlet tapered section, a jet flow section, and an outlet diffusion section. The outlet diffusion section of the nozzle core is connected to an atomizing body mixing chamber. The jet flow section of the nozzle core is in communication with external atmosphere through a core air inlet hole, an air inlet buffering chamber, and a sleeve air inlet hole.

A nozzle assembly that includes a nozzle mount with a first end having a first opening and a second end having a second opening. The nozzle mount has a bore therein that extends from the first opening to the second opening. A diamond orifice is configured to fit within the bore. The diamond orifice is held in place by a retainer within the bore of the nozzle mount. The diamond orifice has a non-circular opening and is positioned within the bore such that a fluid entering the first end of the nozzle mount exits the second end of the nozzle mount through the non-circular opening of the diamond orifice.

A spray tip for a fluid applicator includes a stem configured to be inserted into the fluid applicator. The stem includes a stem pre-orifice portion and an insert receiving portion. The spray tip includes a pre-orifice insert having an inlet and an outlet. The pre-orifice insert is disposed within the insert receiving portion and disposed against a rearward shoulder of the stem.

Various embodiments for an adjustable flow nozzle system having a manifold with a plurality of adjustable flow nozzles in which the flow rate of each adjustable flow nozzle may be individually adjusted are described herein.

A spray tip is configured to atomize thick, viscous fluids. The spray tip includes a pre-orifice piece having an inlet orifice that defines a first restriction in a fluid path through the spray tip. The spray tip also includes a tip piece having an outlet orifice that defines a second restriction in the fluid path. The first and second restrictions are the portions of the fluid path having the smallest flow areas. A cross-sectional area of the outlet orifice is greater than a cross-sectional area of the inlet orifice.

A tip piece for a sprayer includes a tip body extending between a first end and a second end. A passage extends inside the tip body from the first end to a terminal end between the first end and the second end of the tip body. A nozzle extends into the tip body from the second end of the tip body and intersects the terminal end of the passage to form an orifice. A rounded interface is formed on a perimeter of the orifice between the nozzle and the terminal end of the passage.

An additive manufacturing nozzles includes a header (41) extending in a width direction of the chamber and which is configured to be supplied with inert gas from the outside, and a nozzle body (43) connecting with the header (41) in the width direction and is configured to horizontally blow out the inert gas, which is supplied from the header, to a molding area. The nozzle body has a honeycomb part (52) which defines an inside of the nozzle body into flow channels through which the inert gas flows, a blowout part (55) disposed downstream of the honeycomb part and which is connected with the honeycomb part in the width direction. The inert gas passed through the plurality of flow channels is led from the honeycomb part to the blowout part, and a porous part (54), which has openings, is disposed between the honeycomb part and the blowout part.
