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 are 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.

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.

A system for the application of foamable chemical compositions is presented. The application system comprises an ergonomic handle/adapter removably attachable to a pressurized source of a foam product, the handle having inlet and outlet orifices or openings for flow of the foam product from the pressurized source to a nozzle, the nozzle having an outlet orifice for dispensing the foam product and an inlet orifice for connecting to a flexible tubular connecting member which interconnects the outlet orifice of the handle/adapter with the inlet orifice of the nozzle. The nozzle of the present invention includes design features to produce a fan shaped spray pattern of the foam product and to reduce the incidence of leakage or dripping of either moisture or the foam product at the nozzle's outlet. The tubular connecting member is flexible and therefore allows a user to spray foam into hard to reach places.

An air outlet device is disclosed herein. The air outlet device includes a plenum body portion, the plenum body portion defining an air chamber therein, the plenum body portion including an air inlet configured to be coupled to a supply air source for supplying air to the air chamber; an air nozzle portion fluidly coupled to the plenum body portion and including a nozzle inlet and an exit orifice, the air nozzle portion configured to discharge the air from the air chamber at a substantially uniform velocity through the exit orifice; and an air nozzle extension fluidly coupling the air chamber of the plenum body portion to the nozzle inlet of the air nozzle portion, the air nozzle extension being configured to increase an efficiency of the air outlet device by decreasing the pressure drop that occurs when the pressure energy of the air is converted to kinetic energy.

A slender and funnel-shaped jet nozzle structure includes a plurality of slender tapered diversion channels, a plurality of slender jet nozzles and a conveyer belt. The wall thickness of the slender tapered diversion channel is 1-5 mm. The wall thickness of the slender jet nozzle is 1-5 mm. A thickness of the conveyer belt is 1-5 mm. The slender tapered diversion channel is a hollow slender truncated cone and includes an upper opening and a lower opening. The upper opening of the slender tapered diversion channel is substantively elliptic, and the lower opening of the slender tapered diversion channel is connected to an inlet of the slender jet nozzle. The slender jet nozzle is a hollow slender elliptic cylinder.
