摘要： The present invention provides an infusion pump 10 for providing a flow of a liquid through an tube 28. The infusion pump 10 includes at least two occluders 152, 162 having an open position and a closed position for releasably pinching-off the tube 28. A metering chamber is disposed between the two occluders 152, 162. A first plunger 72 and a second plunger 73 are provided, each plunger 72, 73 having an open position and a closed position for releasably compressing the metering chamber. In the method of the present invention, an occluder 152 releasably pinches-off the tube near the source of the liquid at a first location. The second occluder 162 releasably pinches-off the tube at a second location that is downstream from the source of the liquid 23 and the first location. The tube 28 is released at the first location and a plunger 72 compresses the tube 28 between the first location and the second location, thereby generating a flow of the liquid through the tube 28 in a direction towards the source of liquid 23.

摘要： An improved peristaltic pump using a pumptube comprising a single tube of a relatively rigid and hard fluoroplastic material, preferably relatively rigid and hard polytetrafluoroethylene (PTFE), and a roller strap located between the pressure rollers of the peristaltic pump and the pumptube, is provided. The roller strap prevents direct contact between the pressure rollers of the peristaltic pump and the pumping section of the pumptube. The pumping section of the pumptube is formed or shaped into a flattened, oval-like shape which approximately conforms to the pumptube passageway in the peristaltic pump. The pressure rollers contact the roller strap and then compress the flattened side of the pumptube and, thereby, effecting transport or pumping of the fluid. The use of the strap prevents excessive tube expansion at the output back-pressure, thereby increasing the lifetime of the pumptube. Using the pumptubes and peristaltic pumps of this invention, corrosive, viscous, sensitive, biological, and/or high pressure fluids can be readily handled. The pumptube and peristaltic pumps of this invention are especially adapted to operate against high back- or counter-pressures.

摘要： A liquid pumping apparatus for pumping liquids, more specifically a linear peristaltic pump apparatus. The apparatus consists of a high durometer compressible elastomeric liquid flow tube (12), an infeed valve assembly (26), an outfeed valve assembly (38), an extensible and retractable actuator anvil (34) having a round surface which engages the flow tube (12) at all times, an opposed anvil (24.1) having a round surface in engagement with the flow tube at all times, the flow tube being held between the anvils (34, 24.1) in a slightly compressed state when the anvil (34) is retracted, and a control assembly (100) for causing the movable anvil to be sequentially extended and retracted to cause flow within the flow tube (12) from the infeed valve assembly (26) to the outfeed valve assembly (38). With this apparatus the lumen of the flow tube (12) to the sides of the anvils is not completely reduced to zero volume during displacement compression whereby gas embolisms do not erupt or explode when discharged. Two principal embodiments are disclosed, one having infeed and outfeed check valves which oclude the flow tube, and the other having check valves.

摘要： A medical infusion pump is disclosed which provides for greatly improved accuracy in the delivery of medicaments to a patient. Among the various features included in the instant invention is a pumping body which serves to deform and reform a tube so as to maintain the initial cross-section thereof and thereby preserve the output accuracy of the pump. Also disclosed with regard to the pumping body is a wholly mechanical synchronization of the pumping body and valves associated therewith and coactive with the aforementioned synchronization a mechanical linearization of output of the pumping body per each pumping cycle. Additionally, several features which serve to enhance the utility of the instant invention are also included therein among which is an associated assembly operative to automatically load or disload a tube or IV set into or out of the pumping body. Associated with the assembly operative to automatically load or disload a tube and disclosed herein is an assembly operative to selectively open or close a slide clamp associated with the tube in such a way as to ensure that the tube is occluded such that in combination with the valves associated with the pumping body, a condition of free-flow of medicament is never realized. Additionally disclosed are sensor housings adapted to measure various quantities associated with fluid flowing through the tube wherein the housings are with associated components adapted to achieve a substantially normal orientation with respect to the sidewall of the tube and in the achieving of such normal orientation, expressing an essentially zero elastic stress gradient across the tube.

摘要： A peristaltic pump mechanism comprises a base plate (11) having a generally planar surface for supporting a pump tube (12) to extend at least partially around a circular path defined on said surface, an operating section (10) connectable to the base member (11). At least one rotatable pumping element (21) is mounted on the operating section (10) locally to compress the pump tube (12) and roll around the circular path when the operating section (10) is connected to the base member. A power drive causes the pumping element (21) to roll around the circular path, the pumping element (21) being of conical shape and mounted on the operating section (10) so that the axis of the element is substantially co-incident with the centre of the circular path. In this way essentially no slippage takes place between the pumping element and the base plate.

摘要： A pump housing supports a plurality of pump segments each having a raised pump cavity enclosed by a resilient diaphragm sealed to the pump cavity. A compression plate supports a plurality of rollers against the pump segments. The compression plate is rotatable with respect to the pump housing to move the rollers across the pump segments deforming the diaphragms and expelling fluid from the pump segments. Fluid passages couple each pump cavity to a source of fluid and a fluid output. As each roller rolls across each diaphragm to expel fluid from the pump segment, the resilience of the diaphragm draws fluid into the pump segment behind the roller to refill the pump segment.

摘要： A peristaltic pumping mechanism is provided with a non-permeable peristaltic circuit comprising two strips of thin metal laser bonded at their edges to form a tube. In one embodiment, the non-permeable tubing takes the form of a continuous loop having input and output ports. In another embodiment, the tubing is open and generally U-shaped. In still another embodiment, a dual-tube circuit is provided, wherein a central, metal tube is disposed within an outer elastomeric tube having an inner diameter larger than the outer dimension of the metal tube. The elastomeric tube supports the metal tube only at the ends of the circuit, enabling the metal tube to “float” within the elastomeric tube.
