The present invention relates to a multi-coupling device of the plate type for the simultaneous connection of a plurality of hydraulic, electric and pneumatic lines through quick couplings. The device according to the present invention is characterized in that it comprises bayonet coupling means which allow the coupling of the two plates by means of the relative sliding of the mobile plate with respect to the fixed plate. By virtue of the presence of a dedicated hydraulic circuit which connects the female couplings of the fixed plate to one another, the multi-coupling device according to the present invention allows to separate the step of coupling of the plates from the step of hydraulic connection of the male and female couplings.

In some examples, a connector assembly configured to connect a tube to a peritoneal dialysis cycler comprises: a connector piece having a bore, wherein a proximal end of the bore defines an opening in a proximal portion of the connector piece configured to receive and deliver fluid from and to the cycler; and a connector body having a bore, wherein a proximal end of the bore defines a cavity in a proximal portion of the connector body configured to receive a distal portion of the connector piece to position the distal end of the bore of the connector piece in fluid communication with the proximal end of the bore of the connector body. The distal portion of the connector body comprises a tubular portion configured to form an interference fit with the tube. A collar of the connector body is configured to grip an outer surface of the tube.

An oil drain receptacle attachment, integrated system and method of use for providing a closed, clean catch system for the requisition of used motor oil for recycling. The oil drain attachment itself is positioned between a flexible drain tube and a collection receptacle where the reversibly attachable oil drain attachment allows for securing of the flexible tubing to an opening of the receptacle, in operation, that is capable of initiating and ceasing flow, through an ‘on’ and ‘off’ functionality, in addition to intermediate, partial opening and closing positions, as well as providing ventilation that facilitates the exit of air with the introduction of used oil into a collection receptacle for transportation and disposal.

A hydraulic coupling bush which is actuated in order to close or open the coupling includes a coupling housing and a bush body which displaceable therein and which has a plug space for receiving a coupling plug, a supply space for fluidic connection to an external supply channel, a low pressure space for fluidic connection to a pressure medium sink, and an interior space connected fluidically to the supply space, a supply seat valve device being provided, via the actuation of which a supply flow path can be configured between the supply space and the plug space, and a relief seat valve device being provided, via the mechanical actuation of which the interior space can be relieved of pressure toward the low pressure space, and via the hydraulic actuation of which, which is dependent on the pressure in the interior space, the pressure in the interior space can be limited.

The invention proposes a method of modernizing a flexible conduit line (50), wherein the modernization method comprises the following steps performed in at least one end fittings joint (11, 12, 13), namely, removing a check valve (16) or a plug (17) from at least one outlet port (15) of an end fitting (111, 121, 131), removing a check valve (16′) or a plug (17′) of at least one outlet port (15′) of an adjacent end fitting (111′, 121′, 131′), installing a tubular line (90) in an external position to provide fluid communication between said at least one outlet port (15) of the end fitting (111, 121, 131) and said at least one outlet port (15′) of the adjacent end fitting (111′, 121′, 131′). The invention further proposes an end fittings joint (12) comprising an end fitting (121) and an adjacent end fitting (121′), the end fittings joint (12) comprising a tubular line (90) positioned externally to the end fittings (121, 121′) in order to establish fluid communication between at least one outlet port (15) of the end fitting and at least one outlet port (15′) of the adjacent end fitting (121′). The invention further proposes an interconnection module (80) connectable to a first end fitting (121) suitable to be installed in a first flexible conduit segment (52) and connectable to a second end fitting (121′) suitable to be installed in a second flexible conduit segment (53). The interconnection module (80) further comprises a tubular line (90) in an external position configured to provide fluid communication between at least one outlet port (15) of the first end fitting (121) and at least one port (15′) of the second end fitting (121′).

A probe assembly configured to selectively restrict fluid flow through an outlet of a closed transfer system. The probe assembly has an elongate probe body with a top end portion, a bottom end portion, an outer wall, and an internal structure defining a fluid chamber extending from the bottom end portion to the top end portion. The fluid chamber has a fluid chamber inlet at the bottom end portion extending through the outer wall into the fluid chamber and a fluid chamber outlet at the top end portion extending from the fluid chamber through the outer wall. A probe tip with a cylindrical bore is configured to engage the top end portion of the elongate probe body and a probe tip outlet is configured to be in fluid communication with the fluid chamber outlet. A rotating head located circumjacent to the probe tip and adjacent to the probe tip outlet is configured to rotate about the probe tip. The rotating head having an inner surface, an outer surface, and a vane extending from the inner surface through the outer surface.
