The pinch clamp has a locking assembly that includes two members for securing the jaw assemblies of the pinch clamp in place. The two members are a stud and a nut threaded on the stud. The stud has a spherical base pivotally mounted on an end of one jaw assembly and an arcuate boss projecting from the spherical base into mating sliding relation with the arcuate recess of the jaw assembly to limit pivoting of the base to a single plane. A threaded stern extends from the spherical base and is disposed in a bifurcation of the jaw assembly.

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 multi-tubing pinch valve assembly including a receiving space defined between a pinch protrusion and tubing contact body. The multi-tubing pinch valve assembly is moveable between a retracted state and an extended state. In the extended state, multiple tubes disposed in the receiving space are pinched, restricting flow therethrough. In the retracted state, multiple tubes are capable of being loaded into and/or out of the receiving space.

A touchless beverage dispensing valve may include a downspout assembly having a body having walls with a slot therein, a channel, an upper and a lower opening, with the slot in the channel between the upper and lower openings. The downspout assembly may include a lateral member extending laterally from the downspout assembly and engaging the wall adjacent the slot. A pinch member may be partly enclosed within the lateral member and dimensioned to move partially through the slot. A touchless push bar and the pinch member may move the pinch member in and out of the slot. A coil spring may engage the lateral member and the pinch arm urging the pinch arm at least partially through the slot of the body. A flexible insert may be dimensioned to tightly fit against the walls of the channel of the body, the insert having an open top and an open bottom.

A system is described herein that can irrigate a tissue site using negative-pressure. The system may include a tissue interface configured to be placed adjacent to the tissue site, and a sealing member configured to be placed over the tissue interface to form a sealed space. The system may also include a negative-pressure source configured to be fluidly coupled to the sealed space and a fluid source. The system may further include an irrigation valve. The irrigation valve can have a fluid inlet configured to be fluidly coupled to the fluid source. The irrigation valve can also have a fluid outlet configured to be fluidly coupled to the sealed space. The irrigation valve may also include a clamp configured to be actuated by the negative-pressure source to regulate fluid flow from the fluid source through the fluid outlet.

A tube holder includes a tube clamp having a housing and a clamping mechanism. The housing has a tube entry along a major surface thereof. A first tube passageway extends from the tube entry into the housing, and a tube receiving channel is coupled to the first tube passageway. The clamping mechanism comprises a lever handle user operable to transition from a first position to a second position. A gate is coupled to the lever handle, and a tube pinch is coupled to the lever handle. When a tube is peripherally inserted into the tube receiving channel and the lever handle of the clamping mechanism is in the second position, the gate prevents the tube from exiting the housing via the first tube passageway, and the tube pinch pinches the tube so as to prevent a flow of a fluid through the tube.

A beverage dispensing valve may include a downspout assembly having a body having walls with a slot therein, a channel, an upper and a lower opening, with the slot in the channel between the upper and lower openings. The downspout assembly may include a lateral member extending laterally from the downspout assembly and engaging the wall adjacent the slot. A pinch member may be partly enclosed within the lateral member and dimensioned to move partially through the slot. A handle and the pinch member may move the pinch member in and out of the slot. A coil spring may engage the lateral member and the pinch arm urging the pinch arm at least partially through the slot of the body. A flexible insert may be dimensioned to tightly fit against the walls of the channel of the body, the insert having an open top and an open bottom.
