  • Patent number: 8679075
    Abstract: A system and method for automatically delivering an infusate to a patient is disclosed. The system includes an infusion set and an infusion device. A signaling component disposed on an infusion set component identifies an administration protocol for the infusion set. A detection device operatively connected to the infusion device detects the signaling component and identifies the administration protocol. The infusion device is then configured to operate according to the administration protocol.
    Type: Grant

  • Patent number: 6213723
    Abstract: 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.

  • Patent number: 6129517
    Abstract: A medical infusion pump is disclosed which has a tube present sensor that determines the position of the tube within a pumping body. The tube present sensor having a pivotable sensor arm with a blade which engages the tube. The pivotable sensor arm having a sensor flag which actuates an optical switch to signal that the sensor arm is in engagement with the tube. The sensor exchanges positional information with a pump controller to affect operation of the pump.

  • Patent number: 4690562
    Abstract: An apparatus and method for analysing a gas of the kind adapted to produce an interference pattern displacements of which are indicative of changes of the constitution of the gas involves exposing an array 8 of photosensitive elements to the interference pattern. Respective digital indications of the intensity of the interference pattern falling of the elements are produced by means of a timing circuit 16 adapted to clock data out of the array 8 as a series of analogue pulses which are held by a fast peak detector 17 and converted by an analogue-to-digital converter 18 into digital indications. The position of a principal peak of the interference pattern is then determined by means of a microprocessor (not shown) adapted to determine the best fit of the digital indications with appropriate pre-stored values.
