A cleaning installation of a heat exchanger includes a heat exchanger linked upstream to an intake duct for a fluid and downstream to an outlet duct for the fluid. A system is provided for recovering cleaning bodies from the outlet duct after cleaning of the exchanger by the bodies and for reinjecting bodies into the intake duct. The system includes a member capable of being displaced between a first position in which the system is configured to recover and contain cleaning bodies in the mobile member, and a second position in which the system is configured to take fluid from the intake duct and reinject, into this duct, via the mobile member and under the action of the fluid taken, cleaning bodies contained in the member.

The present invention relates to: a tubular medical device cleaning ball; and a manufacturing method therefor and, more specifically, to: a tubular medical device cleaning ball capable of cleaning a tubular medical device by being injected together with a cleaning solution without using a separate brush and the like in order to clean the tubular medical device inserted into the human body during minimally invasive surgery; and a manufacturing method therefor. To this end, the cleaning ball is manufactured as a sphere having surface roughness and a cavity therein.

A surgical tool, systems, and method for cleaning an anatomical space is provided. At least one brush is disposed on a shaft extending through a tube. The tube includes a corresponding brush slot for each brush. A motor is operable to rotate the shaft to cause the at least one brush to move from a closed position to a cleaning position. The at least one brush is positioned entirely inside of the tube when in the closed position and at least partially outside of the tube when in the cleaning position. A fluid source is operable to supply fluid to the at least one brush as the at least one brush passes through the brush slot.

A method of minimizing material mixing in a piping system during a transition between a first material and a second material includes providing a plurality of pipe pigs in a first pipe section with the plurality of pipe pigs being sufficient to substantially fill a cross-section of the first pipe section and to define a plug having a leading edge and a trailing edge such that the leading edge is in contact with a first material and the trailing edge is in contact with a second material. Each pipe pig has a nominal size that is smaller than an effective diameter of the first pipe section. The plug is moved through the piping system by moving the second material. Advantageously, mixing of the first material and the second material is inhibited by the plug.

A ball trap screen for use with T type ball traps having a ball trap extension in which the ball trap screen includes a cone shaped inlet; an elbow, at least a portion of which includes a substantially planer solid area; a first screen section extending between the cone shaped inlet and the elbow; and a second screen section extending from the elbow into the ball trap extension; wherein at least a portion of the cone shaped inlet includes a cone solid blocking element, the first screen section includes a first solid screen blocking element and the second screen section includes a second solid screen blocking element. A method of enhancing the movement of the cleaning ball through the ball trap by blocking portions of a ball trap screen deployed within a ball trap housing so as to modify the fluid flow through the ball trap.

Disclosed are cleaning devices and methods of use thereof for cleaning a vertical stack plumbing system. The cleaning device includes a first cylindrical body defining a first opening for selectively introducing a predetermined amount of cleaning medium into the cleaning device; a second cylindrical body defining a second opening configured to maintain airflow and venting of the vertical stack plumbing system when the cleaning device is in use, the first and second cylindrical bodies being directly connected to a main body of the cleaning device and in fluid communication with one another through the main body; and an attachment member defining a third opening that is directly connected to the main body of the cleaning device, the attachment member configured for direct removable attachment to a plumbing waste pipe in the vertical stack plumbing system and for receiving the cleaning medium therethrough to introduce the cleaning medium into the vertical stack plumbing system.

A ball circulation pump skid includes a piping manifold mounted to a base frame, having a first inlet and a first outlet each connected to a pump, and provided with a second inlet and a second outlet connectable to an external device. The manifold houses a ball collection capsule configured to permit flow of fluid and entrained cleaning balls into the ball collection capsule in a first flow direction and to permit flow of fluid and entrained cleaning balls out of the ball collection capsule in a second flow direction. Valves mounted to the piping manifold are operative to create alternately a first fluid flow path and a second fluid flow path through the piping manifold, to capture the cleaning balls in the collection capsule prior to fluid flow to the pump and to re-entrain the cleaning balls prior to fluid delivery to the external device.
