    Abstract: Needle free valve device (1) for controlling the flow of fluid in a pathway, the device (1) being operable in a closed and in an open configuration and comprising a first component (3), a second component (9), a locking means configured to selectively engage the first component (3) with the second component (9) in the open configuration when the first component (3) is displaced in an opening direction (23) along a valve axis toward the second component (9) or in the closed configuration when the first component (3) is displaced against the opening direction (23) away from the second component (9), and a sealing component (15) having a resilient portion (19), the resilient portion (19) comprising at least one slit (26) and engaging the second component (9) to provide a seal in the closed configuration, wherein the resilient portion (19) is adapted to move, buckle or flex to enable fluid flow through the at least one slit (26) upon application of a mechanical force of the second component (9) on the resilient portion (19) against the opening direction (23) when assuming the open configuration, and wherein the resilient portion (19) is adapted to return the valve device (1) to the closed configuration when the mechanical force is no longer applied.

    Abstract: An anti-free-flow valve for engagement for use with an enteral feeding or infusion pump has a (1) first component connectable to a first tube and having a first cavity and a sealing element and (2) a second component adapted to be connected to the first component and a second tube and having a second cavity, a valve seat and a flexible portion, the sealing element and the valve seat being sealingly engageable to control fluid flow between the first and second cavities, the valve being configured such that applying an axial tension force between the first and second components brings the valve into an open condition, and improvements including: the second component's flexible portion including at least one bellows having a spring function in the axial direction; and a housing at least partially covering the second component and configured to operate as a stop limiting the axial movement of the second component.
