  • Method and device for detecting malfunction in a gravity fed intravenous delivery system
    Patent number: 6974438
    Abstract: Described is an accurate, easy to use and inexpensive device and method for substantially immediate detection and indication of malfunction in an intravenous delivery system. The two piece device includes a disposable conduit body interconnected with the tubing of an intravenous delivery system and a reusable clamp apparatus that is deployed around the conduit body. The conduit body is highly sensitive to pressure changes inside the tubing. The clamp apparatus contains a sensing mechanism that discerns the responses of the conduit body to the change in line pressure from below to above atmospheric pressure. Also located in the clamp apparatus is an indication system that indicates if that change in pressure has occurred.

  • Method and device for detecting extravasation
    Patent number: 6425878
    Abstract: A method and device for detecting extravasation employs a non-invasive sensor system deployed on the skin to identify changes in both subcutaneous interstitial fluid pressure and skin temperature. Preferably, the system monitors the sensor system outputs to identify a sequence of a skin temperature drop followed by a interstitial fluid pressure increase. This pattern is distinctive of the occurrence of extravasation, thereby providing very reliable detection. Most preferably, a simple sensor structure based upon multiple piezoelectric film sensors is used.
