A medical tube comprises a spirally wound bead forming a plurality of successive coils. Each of the plurality of successive coils has an internal diameter and an external diameter, and a spirally wound film extending between adjacent coils of the bead. The film is bonded at a first location on a surface of a first coil of the bead and at a second location on a surface of a second coil of the bead. The first coil is adjacent to the second coil and the first location and the second location are located between the internal diameters and external diameters of respective first and second adjacent coils. Together the spirally wound bead and spirally wound film form a conduit.

An in-line quick connector has a female connector body arranged to receive a male connector body in an interior cavity. The male connector body includes a bifurcated tubular member that includes resilient latching arms co-operable to engage latching members located within the interior cavity of the female connector body. The male connector body and female connector body each further include a raised annular flange. Fixed key members located on the male connector body flange engage slots located on the female connector body flange.

There is provided a tube coupling configured to connect and couple two tubes that are configured to cause a fluid to flow inside the two tubes. The tube coupling includes: a male connector including a first pipe configured to cause the fluid to flow inside the first pipe, and an insertion part having a protruding shape protruding in an axial direction that is an insertion direction; and a female connector including a second pipe configured to cause the fluid to flow inside the second pipe, and an insertion receiving part having a recessed shape recessed in the axial direction and coupled to the insertion part when the insertion part is inserted into the insertion receiving part. The insertion part includes a first spring, a first pressing member having a protruding shape, a first seal member having an annular shape, and a first outer peripheral member surrounding the first pressing member.

A cover for a connector, wherein the cover is adapted to be locateable over at least a portion of the connector, and wherein the connector has a fluid pathway formed therethrough. The connector has a first portion and a second portion, and wherein, when the cover is located over the portion of the connector, ingress of impurities into the fluid pathway is prevented.

A push-in tube connector port for connecting a tube to a pressurized fluid system is provided. The push-in port includes a central recess for receiving the tube, a sealing arrangement inside of the recess, a locking ring engaged within the recess, and a tube gripping ring having an inwardly directed gripping edge. The locking ring has a U-shaped cross-section. A number of circumferentially distributed slots subdivides an outer ring wall of the locking ring into a number of outer ring wall portions configured to be elastically deflected towards the center by the flange of an insertion end opening, when the annular double ring component is pressed into the recess, and to elastically flex back outwardly once the outer ring wall portions have passed the flange such that an upper edge of each of the outer ring wall portions engages an inner surface of the flange to secure the locking ring in the recess.

Provided is a connector including: a plug to be attached to an opening of a liquid storing container and attached to an inner peripheral surface of the opening; a key ring to be attached to an outer peripheral surface of the opening extending along an axial line and including a key hole portion disposed at an outside of the outer peripheral surface with respect to the axial line; and a socket to be detachably attached to the plug and including a key rod portion to be engaged with the key hole portion. The plug and the socket are coupled together in a state where the key hole portion and the key rod portion are engaged with each other.

Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a sterile connection for drug delivery. In some embodiments, the fluid coupling devices can be implemented as multi-use, sterile fluid coupling devices that are configured to reduce the likelihood of fluid spillage when being disconnected.

Provided is a connector including a plug and a socket. The socket includes: a socket body in which a second liquid outflow passage and a second liquid inflow passage are formed; a ball lock mechanism that is attached to the socket body and fixes the socket body to a key ring; and a switching mechanism that switches an open state and a closed state of a rotary valve. The switching mechanism includes an opening/closing arm that regulates releasing of the fixation of the socket body to the key ring by the ball lock mechanism in the open state.
