    摘要： Pump for conveying liquid, having at least one pump housing with at least one inlet and at least one outlet, and including an inner circumferential surface and a geometric axis, where an eccentric is arranged within the pump housing and is moveable eccentrically relative to the pump housing around the geometric axis.

    摘要： A pump for delivering a liquid has a pump housing with at least one inlet and at least one outlet. On the pump housing, there is arranged an eccentric which, with an axis, is rotatable relative to the pump housing. A deformable element between the pump housing and the eccentric delimits at least one delivery path from the inlet to the outlet and forms at least one displaceable seal of the delivery path, which displaceable seal partitions off at least one closed pump volume in the delivery path. By a movement of the eccentric, the displaceable seal is displaceable to deliver the liquid along the delivery path. The inlet and the outlet have an angular spacing to one another in a circumferential direction about the axis, and the seal spans an angle segment in which the delivery path is closed, the angle segment being larger than the angular spacing.

    摘要： In a pump, a flexible tube passes through the pump and is held “normally closed” at an output constriction. The pump includes a pump body and a pump member that can perform two functions by their relative motion. The first function is to open and close an input constriction of the flexible tube. The second function is to compress the section of flexible tube between the input constriction and the output constriction. This section of tube acts as the pump chamber. When closed, the input constriction provides a greater impediment to fluid flow than the output constriction. Therefore, when the input constriction is closed and the pump chamber is compressed, fluid flows out of the pump past the output constriction. When the input constriction is open and compression of the pump chamber is removed, the output constriction closes and fluid can enter the pump by flowing past the location of the input constriction.

    摘要： A tube-pump of the invention comprising; an elastic-tube disposed in a ring-shaped form along the inner surface of a cylindrical chamber, a ring-shaped pressure member driven by an eccentric cam device disposed within said ring-shaped elastic tube which is pressed by the circular motion of said ring-shaped pressure member, and plural supporting means allowing a pressing motion to said elastic tube and preventing continuous rotating motions of said pressing member in a same direction holding said pressure member in said cylindrical chamber by said plural supporting means. By employing this pump construction, elongation of elastic tube and changes of its inner diameter possible by continuous rotations of ring-shaped pressure members into the same direction can be prevented, and at the same time, the pump output capacity can be kept at constant without damaging said elastic tube, remarkably improving the pump durability.

    摘要： A method and apparatus for detecting proximal and distal occlusions of flexible tubing in a positive displacement pump. A volumetric pump (30) includes a motor (146) that rotatably drives a cam assembly (142). The rotating cam assembly actuates a plunger (48), causing it to compress a pumping portion (34b) of a flexible tubing (34), compression of the tubing displaces fluid trapped within the pumping portion, causing it to flow past an outlet cracking valve (52). A proximal pressure sensor (44) and a distal pressure sensor (56) each produce signals indicative of the pressure within the proximal portion and distal portion of the flexible tubing, which are used to determine whether a proximal or distal occlusion of the flexible tubing has occurred. Both pressure sensors comprise strain gauges connected to flexures that apply a spring-biased force against the proximal and distal portions of the flexible tubing. These sensors thereby respond to the cross-sectional size (diameter) of the tubing, as affected by fluid pressure therein. Proximal and distal pressures are thus monitored without violating the integrity of the flexible tubing passing through the volumetric pump.
