  • Patent number: 6123686
    Abstract: The present invention concerns a pump provided with a control module and an attachable fluid reservoir cassette. The control module includes a pumping mechanism for pumping fluid from the fluid reservoir to the patient. The cassette is provided with appropriate indicia to identify differences between a plurality of cassettes. The control module further includes cassette indicia identification structure for identifying indicia on the cassette. One type of cassette identification system includes a projection extending from the cassette and structure associated with the control module which engages the projection. Another type of cassette identification system includes a light reflecting system which utilizes light from the control module and reflected off the cassette. Still other types of cassette identification systems utilize other non-contact switches or sensors to sense indicia on the cassette to identify the cassette from a plurality of cassettes.

  • Patent number: 6112111
    Abstract: The present invention relates to a method and apparatus used to place a catheter having a distal end and a proximal end where the proximal end cannot be trimmed within a patient. The method and apparatus utilize a device operative in locating the tip of a catheter, which includes a detector assembly having a detector and a locator. The detector of the detector assembly is locked into positioned remote from the distal end of the catheter prior to inserting the catheter in the patient. The distal end of the catheter is trimmed, as to define a trimmed distal end, the detector is then unlocked and placed proximate the trimmed end. In the preferred embodiment the detector is locked into place proximate the trimmed distal end and the catheter is placed within the patient.

  • Patent number: 6024539
    Abstract: The invention relates to systems and methods for communicating with ambulatory medical devices, such as drug delivery devices, both locally and remotely. In one embodiment, a caregiver drug pump communicates with a remote patient drug pump for data gathering, trouble shooting, and operational program changes. The caregiver drug pump is substantially identical in configuration to the patient drug pump. The caregiver drug pump transmits caregiver key input signals to the remote patient drug pump. The patient drug pump receives the key input signals, accesses a desired program, and transmits information for display on the display of the caregiver drug pump. In another embodiment, a computer is provided for communicating locally and/or remotely with a drug pump. The computer may include a display with an image of a pump. The computer may be operated through the use of a mouse or touch screen with respect to the image of the pump, to simulate use of the pump while using the personal computer.
