A connector includes one or more spirals securing a fluid conduit to the connector for fluid communication with another hollow object such as another fluid conduit. The spiral(s) press/compress and seal the conduit around an outer circumference of an end of rigid, hollow insert of the connector. Another portion of the connector may include spiral(s) that press/compress and seal a second conduit around a second end of the insert, or may include a hose-coupler that connects to a second conduit. Thus, two fluid conduits may be fluid-sealed to an inner-passageway of the insert, by tightened spiral(s) or by tightened spiral(s) and coupler combination, so the conduits are in fluid communication with each other. The spiral(s) may be retained in, and released from, the tightened condition, by a ratchet-based latching and unlatching system.

A critical containment room feed-through assembly with a weldment comprising a coupling member, a first gasket that is configured to seal the weldment to an interior wall or ceiling of the critical containment room, an escutcheon plate, a second gasket that is configured to seal the escutcheon plate to an exterior surface of the critical containment room directly opposed to the weldment, and a plurality of adjustable coupling devices that are configured to engage both the weldment and the escutcheon plate so as to tighten the weldment, the escutcheon plate, and both of the gaskets against the interior and exterior critical containment room surfaces.

There may be provided a connector for a liquid container. The connector may include a connector body, and a through-hole for fitting on a neck portion of the liquid container. The connector may further include a restraining arrangement positioned proximal to the through-hole. The restraining arrangement may include a first restraining member and a second restraining member extending towards a central axis of the connector body. The first restraining member may have a distal end that extends further than a distal end of the second restraining member. The distal end of the first restraining member may engage the neck portion of the liquid container at a first position, and the distal end of the second restraining member may engage the neck portion of the liquid container at a second position. The connector may further include a connector-to-key-interface arrangement configured to mate with a corresponding surface of a key member.

A connector and tubing combination includes a tubing segment with an end piece, such as a tubing flange. The tubing flange can be secured within the connector by an outer sleeve and an inner sleeve of the connector. Both of the inner sleeve and the outer sleeve are located outside of the tubing flange and the tubing segment. In addition, the inner sleeve, outer sleeve and the tubing flange are mechanically connected.

An adapter for putting two incompatible medical systems in fluid communication with each other. The adapter may have a continuous outer diameter and may include two segments: a first segment composed of a rigid material and including a first portion and a second portion, the first portion having a continuous outer diameter and the second portion defining one or more flanges, the first segment defining a first passage therethrough; and a second segment composed of a flexible material and coupled to the first segment, including a first portion and a second portion. The first portion of the second segment may have an inner surface configured to surround the flanges of the second portion of the first segment, and the second portion of the second segment having a tapered inner surface, the second segment defining a second passage therethrough that is continuous with the first passage.

A flexible duct having a hollow tube shape. The flexible duct includes at least one end, and an opening defined by a first edge of the at least one end and forming a duct inlet or duct outlet. The at least one end includes at least a first attachment and a second attachment, and the first attachment and the second attachment are different. The first attachment and the second attachment can be used independently of one another to connect the at least one end to a first inlet or a first outlet. In one embodiment, a flexible duct includes an attachment that is a cuff. In another embodiment, a connector includes two different attachments and the connector can be affixed to a flexible duct end. In another embodiment, a method includes providing a flexible duct with different attachments at one end of the flexible duct, and flowing air through the flexible duct. In a further embodiment, a method includes providing a connector having two different attachments.

A pressure hose (1) for a water-carrying system is shown and described, especially for connecting sanitary taps or for connecting parts of the water-carrying system, having a corrugated inner hose (2) made of plastic, wherein at least one hose end (3, 5) of the pressure hose (1) is provided with a connecting piece (4, 6), designed such that it differs from the inner hose (2), for joining the pressure hose (1) to a complementarily designed connecting piece of a sanitary tap and/or a part of the water-carrying system. According to the invention, it is provided that the inner hose (2) and the connecting piece (4, 6) are formed as one piece and the inner hose (2) and the connecting piece (4, 6) are preferably produced via extrusion in a common extrusion process.

A plug connector arrangement for media lines including a connecting body and a lug component. The connecting body features a fluid channel and at least one receiving opening for at least partial accommodating of the lug component in communication with the fluid channel. The connecting body and the lug component being connected to each other by a connecting element that establishes a first positive-locking snap-in connection with the connecting body and a second positive-locking snap-in connection with the lug component. Also provided is a method for connecting media lines for production of such a plug connector arrangement.
