Abstract: An apparatus, system and method for regulating fluid flow are disclosed. The apparatus includes a curved, elongated support member elastically deformable and having first and second ends. The apparatus also include an opposing support member configured to position a tube against the curved, elongated support member between the first and second ends. Deformation of the curved, elongated support member by movement of the first and second ends toward each other reduces an internal volume of the tube.

Abstract: A pump for pumping fluid includes a tube platen, a plunger, a bias member, inlet and outlet valves, an actuator mechanism, a position sensor, and a processor. The plunger is configured for actuation toward and away from the infusion-tube when the tube platen is disposed opposite to the plunger. The tube platen can hold an intravenous infusion tube. The bias member is configured to urge the plunger toward the tube platen.

Abstract: Apparatus and methods for transporter shaft coupling and decoupling to assure alignment of a user interface with a control shaft through matching asymmetric cylindrical surfaces and alignment of an upper shaft segment and a lower shaft segment with ribs meshing with grooves on rings attached to the upper shaft. A tone confirms proper connection. Alignment apparatus is protected from damage associated with torques applied to the control shaft by tab features designed to first give way before other damage is incurred and from moisture by apparatus that seals the connection between upper and lower shaft segments. The user is protected from sudden loss of control by requiring the user interface to execute a sequence of linear and rotational manipulations during assembly of the shaft.

Abstract: A neck extension includes at least one layer of ballistic material that is shaped to have a nose portion and a throat portion located below the nose portion, which generally correspond to a nose area and mouth area of a face mask. A left neck portion and a right neck portion each extend from the nose portion and throat portion and are configured to wrap around a user's neck when worn. An inner surface of the neck extension attaches to the face mask. The throat portion may be shaped to extend below the mask to provide protection to the user's throat.
