An encapsulated valve system includes a first housing portion having a first facing surface, the first facing surface comprising a plurality of branch pathways formed as a recess within the first facing surface. The valve system further includes a second housing portion having a second facing surface, the second facing surface comprising a plurality of branch pathways formed as a recess within the second facing surface. A disposable conduit is configured to be interposed between the first and second housing portions and disposed within the recess of the first facing surface and the recess of the second facing surface. The disposable conduit is thus sandwiched between the first and second facing surfaces. A plurality of pinch valve actuators are mounted on one or both of the first housing portion and the second housing portion, the plurality of pinch valve actuators configured to pinch the disposable conduit at selective branch pathways.

A clamp for selectively compressing a portion of tubing, such as an extension leg of a PICC or other catheter, is disclosed. The clamp is able to be opened or closed with a thumb and finger of a single hand of a user and is slidably attached to the tubing so as to enable its placement as desired along the tube. In one embodiment, the tubing clamp comprises a body including first and second body portions hingedly connected to one another in a clamshell configuration, a latch for releasably latching the first and second body portions together, and at least two tube compression members. The tube compression members cooperate to compress and occlude a portion of tubing passing through the tubing clamp when the first and second body portions are latched to one another.

The present invention includes an apparatus and method for a hands-free foot pedal to attenuate and interrupt suction that attaches externally around suction tubing, in the context of any system where the flow of suction is through tubing.

Pinch clamps are provided which generate positive displacement while also preventing rebound. To prevent rebound while providing positive displacement, the upper and lower clamping surfaces may be configured to form a pinch profile along which the tubing is compressed with the pinch point being formed at the distal end of the pinch profile. To further prevent rebound, the lower arm of the pinch clamp can include blocking ribs that interface with the upper clamping surface to prevent distal travelling of the pinch point even if the upper arm is forced into an over-engaged position.

A valve assembly for a leak resistance drinking cup is selectively configurable between a sealed position and an unsealed position. The valve assembly includes a plug having an inner surface, an outer surface, and an opening extending through the plug from the outer surface to the inner surface. An amount of vacuum acting on the outer surface of the plug needed to move the valve assembly from the sealed position to the unsealed position is less than the amount of internal pressure acting on the inner surface of the plug needed to move the valve assembly from the sealed position to the unsealed position.

A valve device suitable to selectively obstruct a flexible tube, includes a first body and a second body operatively associated with each other, which are mobile with respect to each other along a sliding axis, thus configuring an open operating position and a closed operating position and thus defining a passage gap configured to be passed through by the flexible tube. The invention also concerns a machine for preparing beverages which includes a valve device and a corresponding functioning method.

A clamp device for a flexible tube which can minimize the sealing area and prevent leakage of fluid and achieve easy release of the clamp device of a flexible tube. A clamp device for a flexible tube comprising: one branch formed with a first projection; the other branch formed with a second projection opposing to the first projection; an intermediate part connecting the one branch and the other branch each other; and an engaging part formed on a tip end of the other branch adapted to be engaged with an engaged part formed on a tip end of the one branch; flow of fluid within the flexible tube laid between the first projection and the second projection being able to be blocked by elastically bending the intermediate part and engaging the engaging part and the engaged part each other to clamp the flexible tube between the first and second projection wherein the clamp device comprises a positioning part for positioning the first and second projections in the longitudinal direction of the flexible tube under the clamped state of the flexible tube with engaging the engaging part and the engaged part each other.

An adjustable reusable flexible flow regulation and clamping element is described. The flow regulation and clamping element includes a first flexible hinge. The flow regulation element further includes a locking element and a set of receptacles. The set of receptacles includes multiple notches, each of which is able to receive and retain the locking element. A flow regulation clamp includes a locking element, a flexible hinge coupled to the locking element, and first and second compression surfaces, each surface coupled to the flexible hinge. An adjustable clamp that includes a locking element, a plurality of locking receptacle, first and second flexible hinges, and first and second compression surfaces. The flow regulation element may be able to be used in a range of applications, including toilet fill, irrigation, wearable hydration, hydroponics, etc.
