    摘要： An apparatus includes a compressor, which is configured to compress air and includes an input port and an output port, an output conduit coupled with the output port and configured to receive the air from the compressor, an input conduit coupled with the input port, a switching valve coupled with the output conduit and with the input conduit, and configured to couple a pneumatic surgical cutting tool, alternatingly, with the output conduit and with the input conduit, and a supply conduit coupled with the input conduit and configured to supply the air, to the input conduit, from a surrounding environment. The supply conduit includes a one-way valve configured to inhibit the air from escaping from the input conduit to the surrounding environment when the compressor is idle. Other examples are also described.

    摘要： A fluid mixing device for mixing a first injection fluid and a second injection fluid includes a first fluid inlet, a second fluid inlet, a mixing chamber in fluid communication with the first and second fluid inlets, and an outlet port in fluid communication with the mixing chamber. The first fluid inlet is configured to conduct the first injection fluid in a first direction and has a first redirecting surface. The second fluid inlet is configured to conduct the second injection fluid in a second direction along a different axis from the first direction and has a second redirecting surface. The mixing chamber is configured to mix the first injection fluid and the second fluid together. The mixture of the first injection fluid and the second injection fluid exits the fluid mixing device via the outlet port.

    摘要： A valve member for a connector includes a head portion, a body portion, and a circumferential lip seal extending radially outward from an outer surface of the head portion. The head portion includes a top section defining a first seal portion. The body portion extends longitudinally from the head portion and defines a second seal portion at a proximal end thereof. The second seal portion is disposed distally to the first seal portion. The circumferential lip seal is disposed between the first and second seal portions.

    摘要： A valve assembly embodiment includes first and second valve devices and a coupling mechanism. Each of the first and second valve devices can include first and second fluid pathways and first and second valve members respectively positioned at the first and second fluid pathways. Both the first and second valve members can have an open position that permits fluid flow and a closed position that prevents fluid flow along the first and second fluid pathways past the first and second valve members. The coupling mechanism can couple to each of the first and second valve members. When the valve assembly is actuated, the coupling mechanism can be configured to transition one or both of the first and second valve members between the open and closed positions.
