Fluid management systems for handling pressurized fluid connect various subsystems or subunits without the need to use reinforced tubing. The system utilizes one or more segments of unreinforced conduit that are encapsulated at various points along a length of the segment with one or more rigid encapsulating members. The unreinforced conduit may be made a disposable element while the rigid encapsulating members may be re-used. In one aspect, the encapsulating member may include a two-part valve body that surrounds and encapsulates a portion of the unreinforced conduit. In another aspect, the encapsulating member may include a two-part jacket that surrounds and encapsulates a portion of the unreinforced conduit. The two-part valve bodies and two-part jackets may be joined at various points within the system as part of the overall flow system.

A pinch valve 1 comprises a tube body 3 made of an elastic material having a flow path formed inside, a pressing part 4, a rod member 6 attached to a front end of the pressing part 4, and a coupling part 35 provided on the outer surface of the tube body 3 and coupling the rod member 6 to the tube body 3 in a transverse arrangement with respect to the tube body 3, wherein pressing or releasing the tube body 3 by the pressing part 4 through the rod member 6 makes the tube body 3 deform and opens or closes the flow path.

A pinch clamp and mount are provided. The pinch clamp includes a first member and second member including rounded pinch surfaces. The second member is pivotably coupled to the first member at a first end. A threaded shaft is pivotably coupled to a second end of the first member. A second end of the second member includes a seat configured to receive the threaded shaft and a nut thereon. The seat includes protrusions at the second end that prevent the nut from sliding out of the seat. The mount includes a body having a flat bottom surface. An internal wall defines a through hole in the flat bottom surface. Two guide rails on a top surface of the body define a central slot configured to receive the clamp. A pair of keyed slots within the two guide rails are configured to receive a pair of keyed projections on the clamp.

A dual latching microvalve is capable of a metastable state, wherein a one or more complete flow paths are open, before switching to another state that allows only an inlet or outlet valve to be open at any time on any fluid path. One valve mechanism uses a cam to alternately open and close two valves, with an external force applying pressure to move one valve arm onto a resting position on the cam, thereby opening the closed valve and provided an uninterrupted flow path through the dual latching microvalve. The metastable state provides, for example, a means to prime the pump before operation, such as pumping of insulin into a patient. When released from the metastable state, the dual latching microvalve operates in a fashion whereby opening of both valves simultaneously is prevented, thereby protecting the patient from injury.

Disclosed is a throttle including: an upstream and downstream flanges; a flexible sheath that extends therebetween; a plurality of sets of shape memory alloy wires, extending between the flanges, that are (i) circumferentially aligned about the flanges; and (ii) exterior to the flexible sheath; and (iii) configured to contact an outer boundary of the flexible sheath, wherein: a first set of the plurality of sets of shape memory alloy wires form a first profile when exposed to a first temperature, causing the flexible sheath to form the first profile having a first internal diameter; and a second set of the plurality of sets of shape memory alloy wires form a second profile when exposed to a second temperature that is lower than the first temperature, causing the flexible sheath to form the second profile having a second internal diameter that is smaller than the first internal diameter.
