    • A peristaltic pump (1) comprises a flexible tube (2) for guiding a liquid to be pumped, a compression mechanism (5) being actuatable for compressing the flexible tube (2), an upstream valve mechanism (3) arranged in an upstream direction with respect to the compression mechanism (5) and being actuatable to selectively open or close the flexible tube (2) upstream of the compression mechanism (5) and a downstream valve mechanism (4) arranged in a downstream direction with respect to the compression mechanism (5) and being actuatable to selectively open or close the flexible tube (2) downstream of the compression mechanism (5). A drive mechanism (6) periodically actuates the compression mechanism (5), the upstream valve mechanism (3) and the downstream valve mechanism (4) and a pressure sensor (7) measures a pressure signal (P) indicative of a pressure in the flexible tube (2) at a location between the upstream valve mechanism (3) and the downstream valve mechanism (4). For detecting a fault condition, a first signal value indicative of a pressure value downstream the downstream valve mechanism (4) and a second signal value indicative of a pressure value upstream the upstream valve mechanism (3) are computed from the measured pressure signal (P), a threshold value is computed from the first signal value and the second signal value, and the measured pressure signal (P) or at least one signal parameter derived from the measured pressure signal (P) is compared with the threshold value to detect the fault condition. In this way, a method for operating a peristaltic pump is provided which allows for a safe and reliable detection of a fault condition such as an upstream occlusion or a downstream occlusion.

    • 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.
