An intermittent, injection port assembly includes a flexible valve member of the type which is laterally deflected when moved from a closed position to an open position. A high flow non-tortuous flow passage is provided through the injection port assembly by a plurality of lateral passages bypassing a base which supports the flexible valve member.

Provided is a tube joining device that allows a user to easily and appropriately perform setting of tubes which become a joining target, and is capable of preventing occurrence of a joining failure caused by a setting error of the tubes in advance. A tube joining device 1 includes: a first tube holding portion 41 that is capable of holding a first tube T1; a second tube holding portion 42 that is disposed in adjacent to the first tube holding portion, and is capable of holding a second tube T2 at a position that is parallel to the first tube; and a housing 2 that is provided with a cover member 20 that is closed to cover fusion-joining sites C of the first tube and the second tube. The cover member is slidable along a direction in which the first tube and the second tube are disposed in parallel.

The aim of the invention is to avoid the risk of contamination of a bag for medical purposes, in particular to significantly reduce the amount of residual particles of material during the cutting of a tube for access to the bag. The invention proposes a system (1) for producing a bag for medical purposes comprising a tube transfer station (2) having transfer means (3) for transferring a tube (11), which is being transported towards the tube transfer station (2), to a holder (10) and for separating there a tube section (17) transferred to the holder (10) from a remainder (18) of the tube (11), in order to then render the separated tube section (17) connectible to two film layers to form an access to the bag. The tube transfer station (2) comprises at least one air nozzle (55, 57), and an effective area (58) of the at least one air nozzle (55, 57) is directed onto a designated location (20) for separation such that a forced air flow (56) in the designated location (20) forced by air blown out and/or drawn in can be adjusted for separation.

Provided is a tube joining apparatus that allows a user to easily and properly set tubes to be joined, and can prevent occurrence of joining failures due to tube setting errors.

A tube joining apparatus 1 includes a housing, a lid relatively movable toward and away from the housing, a tube holding part that holds a first tube and a second tube individually in a state of being placed side by side in an oblique direction with respect to a height direction of the housing, and a tube pressing part that presses the first tube and the second tube against each other as the lid relatively moves toward the housing.

A method is described for opening a heat bonded sterile connection that includes a skin of material blocking flow between the connection site. The method includes applying external pressure to the connection site.

[Object] To provide a tube joining device in which the degree of freedom of device design is improved.

[Solving Means] A tube joining device 1 includes a delivery mechanism 500. The delivery mechanism includes a first pusher member 542 that is provided to perform forward movement and backward movement along a delivery direction and delivers a wafer WF to a first position PS2 that is set between a take-out position PS1 at which the wafer WF is taken out from a cassette WC and a stand-by position PS3, and a second pusher member 543 that is provided to perform forward movement and backward movement along the delivery direction in combination with the first pusher member, and delivers the wafer from the first position to the stand-by position. An operation of delivering the wafer by the first pusher member is capable of being switched to an operation of delivering the wafer by the second pusher member in synchronization with forward movement and backward movement of the first pusher member and the second pusher member.

A tube seal apparatus including a sealing iron having a tube sealing end, an insulating shroud having a tube clamping end, wherein the sealing iron is at least partially disposed within the insulating shroud. The apparatus further includes an anvil having a cutting detail and a non-stick membrane disposed between the anvil and the tube clamping end of the insulating shroud. The sealing iron and insulating shroud are configured to advance towards a tube to be sealed positioned between the non-stick membrane and the anvil. The tube clamping end is configured to clamp the tube through the non-stick membrane. The sealing iron is configured to advance towards the tube to melt and seal the tube against the cutting detail through the non-stick membrane.
