A thin gas transportation device is provided and includes a shell, a check valve and a gas pump. The shell includes a shell surface, an accommodation slot and an outlet slot. The accommodation slot is recessed from the shell surface and includes an accommodation bottom surface. The outlet slot is recessed from the accommodation bottom surface. The check valve is disposed within the accommodation slot and includes a barrier plate and a valve plate. The barrier plate is disposed on the accommodation bottom surface and covers the outlet slot. The barrier plate includes a first surface, a second surface, a protruding part and a plurality of perforations. The protruding part is protruding from the second surface and located at the outlet slot. The valve plate is coupled to the second surface, and the protruding part abuts against the valve part and seals the valve hole.

Pump systems with pinch valves for surgical procedures. At least some of the example embodiments are pump systems including a stationary housing defining a front face. A tube support extends outwardly from the front face for aligning and supporting a first tube and a second tube. At least one pinch member is movable relative to the tube support by a power actuator operably coupled to the at least one pinch member and configured to have three orientations that define: a first arrangement of the pinch member relative to the tube support configured to pinch closed the first tube, a second arrangement of the at least one pinch member relative to the tube support configured to pinch closed the second tube, and a third arrangement of the at least one pinch member relative to the tube support configured to pinch closed neither the first tube nor the second tube.

Pump assemblies and systems are provided. For example, a pump assembly comprises a pump head, a bezel surrounding an outer perimeter of the pump head, a motor, and tubing. The bezel comprises a bezel upper side, a bezel lower side opposite the bezel upper side, a bezel inlet side extending from the bezel upper side to the bezel lower side, and a bezel outlet side opposite the bezel inlet side and extending from the bezel upper side to the bezel lower side. The bezel defines an inlet channel on the bezel inlet side and an outlet channel on the bezel outlet side, each of the inlet channel and the outlet channel guiding the tubing into the pump head. An exemplary pump system comprises a plurality of pump assemblies that each supply a fluid to a cooling circuit and a base for supporting the plurality of pump assemblies.
