A food reflux reducing two-piece nasogastric tube includes a first tube body and a second tube body. The first tube body has a first connector on one end, and a protrusion edge on an outer side of the first connector in adjacent to the first positioning portion. The first connector has a through hole having a seal portion in adjacent to the first positioning portion. The seal portion has a cross break. A convex portion is on an inner edge of the through hole between the seal portion and the first positioning portion. The second tube body has one end provided with a second connector and an insertion combination tube extending therefrom. Two elastic arms extend from an outer side of the second connector and comprise a hook portion respectively. Thus, the second tube body is efficiently connected with and removed from the first tube body.

A quick connector assembly and process for forming a coupling in a fluid line between a first and a second fluid tube comprises a receptacle body having a cavity extending through the receptacle body to the second fluid tube. A sealing section is located within the cavity and a socket portion extends from the sealing section. The socket portion includes wall bordering a socket opening in alignment with the cavity and includes a pair of latch openings extending through a portion of the wall into the socket opening. A sealing member having a receiver opening is installed in the sealing section with the receiver opening in alignment with the socket opening and the cavity to the second tube. A bracket installed on the wall includes a pair of spring latches, each spring latch extending through a respective one of the pair of latch openings into the socket opening. A first fluid tube having an insertion portion and a raised upset is placed through the socket opening into the receiver opening making a fluid connection to the second fluid tube and causing the upset to be captured by each spring latch. A verifier having fixing fingers and a pair of arms is installed through respective recesses in the wall into the socket opening. Upon the capture of the first fluid tube upset by the spring latches, a force applied to the verifier causes each verifier arm to travel along the upset to rest below a respective spring latch and the fixing fingers to also capture the upset. Verifier symbols located on a surface of each verifier arm are visible through each latch openings verifying that the first fluid tube has been coupled to the receptacle body.

A tube coupling including a female connector a body into which a male connector having an annular collar is inserted axially, and a connection element is provided. The connection element extends in a transverse direction within the body of the female connector. The connection element is designed to interfere mechanically with the collar during insertion of the male connector and to move transversely of its own accord towards the inside of the female connector. The connection element includes a locking hook that cooperates with a locking catch provided in the female connector. The hook goes past the catch as a result of the mechanical interference of the collar that drives axial and radial elastic deformation of the connection element. The hook locks against the catch when the connection element is fully pushed into the female connector.

Provided is a connector to be connected to a first pipe including a bulged portion. The connector includes a retainer. The retainer is movable between a standby position and a restraining position. The retainer includes a locking leg and a biasing leg. The locking leg includes a locking part to be locked to a connector body when the retainer is in the standby position and when the retainer is in the restraining position. The locking leg moves radially outward by contacting with the bulged portion, to thereby release locking of the locking part. The biasing leg is elastically deformed radially outward by contacting with a leading end portion of the first pipe, which is located on a leading end side with respect to the bulged portion, to thereby bias the retainer in a direction toward the restraining position.

A connector is disclosed that includes a coupler having a socket end fluidically connected by a passage to a stem connected to a first fluid tube. A retainer housing having a cavity in axial alignment with the passage is installed on the coupler socket end and a retainer is installed in the retainer housing in a first position. A second fluid tube having a raised bead formed proximate an end portion of the second fluid tube is permitted to be installed into the retainer housing cavity by the retainer when the retainer is in the first position. Installation of the second fluid tube places the bead in the retainer housing and the end portion of the second fluid tube in the coupler passage providing a fluid path between the first fluid tube and the second fluid tube. The retainer is moved to a second position latching the bead to the retainer housing retaining the second fluid tube to the connector.

A connection verifier, including a collar, a circuit board non-rotatably connected to the collar, the circuit board including at least one terminal, a switch rotatably connected to the collar and arranged to contact the at least one terminal, the switch including at least one finger extending in a first axial direction, and an indication device arranged to activate when the switch contacts the at least one terminal.

A fluid coupler includes a socket including a socket body defining a receptacle for receiving a plug. A snap ring is mounted within the receptacle for retaining the plug within the receptacle. The snap ring is moveable between a constricted state in which the snap ring is adapted to retain the plug within the receptacle and an expanded state in which the plug is removeable from the receptacle. A release sleeve is mounted over the socket body. The release sleeve is moveable between a non-actuated position and an actuated position. The release sleeve is configured to move the snap ring from the constricted state to the expanded state when moved from the non-actuated position to the actuated position.

A quick connector assembly includes a male adapter portion (24) having an end and a groove (62) formed therein spaced from the end. The male adapter portion has a through bore. A female housing portion (22) has a body having a through bore generally concentrically aligned with the male adapter portion through bore. A ring (26) cooperates with the female housing portion and the male adapter portion. The ring is in a first position when the male adapter is engaged with the female housing and a second position, different from the first position, when the male adapter is other than engaged with the female housing. The first and second positions can be visually different from one another.

A quick connector and connector body comprises a coupler portion having a fluid passage connected to a first fluid tube. A valve mounted within the fluid passage is movable between a closed and an open position. A receptacle portion coupled to the coupler portion includes a socket cavity adapted to receive a second fluid tube within the socket cavity that causes the valve to move into the open position allowing fluid to flow through the fluid passage from the first fluid tube to the second fluid tube.

A locking member is mounted to the housing to be able to move in the outer diameter direction by a tapered portion of the tubular body, when the tubular body is inserted. The housing is equipped with slits formed to pass a curved portion bent in the inner diameter direction disposed at a leading-end side of the locking member and to lock with the engagement portion of the tubular body mounted on the housing. A gap is disposed between the curved portion, and the end portion of the slit positioned at a side in an opposite direction to the leading-end side of the locking member, so that there is no contact while at least the locking member is moving.
