Abstract: A dosing pump is provided comprising a working membrane defining a working area, and a pump drive for creating an oscillating movement of the working membrane. The direction of the pump drive can be inverted and the displacement element can be moved back and forth. The inventive dosing pump also comprises a position sensor for detecting the position of the pump drive, an electronic control system for the same, and a pump head in which an inlet valve and an outlet valve are arranged. The pump drive comprises a positioning motor and can be displaced back and forth in an oscillating manner, with the part thereof connected to the displacement element, in any range of its entire working displacement, according to a pre-determinable course, for a reduced pump capacity in relation to the maximum pump capacity. At least the inlet valve is externally controlled and comprises a motor-driven valve drive. The electronic control system is connected to at least the motor-driven valve drive(s) of the inlet and/or outlet valves, to the positioning motor of the pump drive, and to the position sensor for detecting the position of the displacement element and/or the pump drive. The combination of the electronically controllable positioning motor, the oscillating movement of the pump drive within any range of its entire working range, and the use of an externally controlled inlet and/or outlet valve significantly enlarges the operative range of the inventive dosing pump.

Abstract: Disclosure is made of a method for electronic polar attenuation of torque profile for positive displacement pumps by a processor where the attenuated torque profile is compared with the shaft displacement angle of the pump input shaft. The processor then signals a motor to power a pump with the result of pumping at a constant pressure at the full range of the designed system flow volume. In addition to the attenuated torque profile, the processor can also account for the response time of the pump drive, the motor inductive reactance, system inertia, application characteristics of the pump, and regenerative energy during deceleration of the pump.

Abstract: A diaphragm dosing pump (1) has a rotary driving motor (3) electrically connected to control electronics (4). The motor is controlled in such a way that at the beginning and end of each dosing operation the driven diaphragm preferably always takes the same starting position, in particular a bottom dead center position. In order to achieve a reliable sealing behavior of the inlet and outlet valves even during slow working strokes and when the pressure difference between suction and compression sides is small, the valves are designed with elastic valve disks mounted without stress between their valve seat and an opposite rib-like stop.

Abstract: A volumetric pump for administering intravenous fluids to a patient comprises a housing having an elongate cavity therein with an open and a closed end. A resilient sheet of material having a centrally-located aperture covers the open end, and a pump shaft is slidably disposed through the aperture to form a sphincter seal therebetween. An inlet conduit leading from a fluid source (an IV bag) passes through the housing into the cavity near the open end thereof, and an outlet conduit leading to a fluid sink (the patient) passes through the housing from the cavity near the closed end thereof. The shaft is driven back and forth in reciprocating motion inwardly and outwardly of the cavity to produce, respectively, a positive pressure forcing fluid out of the outlet conduit to the fluid sink, and a negative pressure forcing fluid from the fluid source through the inlet conduit.

Abstract: An ambulatory volumetric pump apparatus includes a housing defining a channel therethrough having an inlet for receiving a fluid and an outlet for discharging a fluid, a pump operable to pump fluid through the channel, a motor for operating the pump in response to control signals, and a programmable microprocessor for selectively supplying control signals to the motor to cause the motor to operate. The programmable microprocessor is "programmed" by manually setting rotatable knobs having faces which extend through but are generally flush with the housing exterior surface. The knobs include indicia to provide a visual display of the setting of the knobs and thus of the parameters of operation of the pump. An under-pressure sensor is disposed after the inlet of the channel to detect a suction or vacuum in the channel and to signal the microprocessor if such condition is detected. An over-pressure sensor is disposed before the outlet of the channel to signal the microprocessor if greater than expected pressure is detected in the channel. The microprocessor then sounds an alarm, shuts off the motor, or both.

Abstract: The position of a rotating pump element is sensed by a reflective object sensor 406 in association with a view disk 412 coupled to the operative element for rotation in synchrony with the operative element. The view disk 412 has first 422 and second 420 surface portions that present themselves in succession to the reflective object sensor during rotation of the operative element. The first surface portion 422 is spaced at or near the optical focus of the reflective object sensor, whereas the second surface portion 422 is not. The reflective object sensor 406 thus generates different outputs, depending upon whether the first surface or second surface portions are in optical alignment with the reflective object sensor.
