  • Systems and methods to prevent catheter occlusion
    Patent number: 10328251
    Abstract: A system to detect occlusion of an intravenous catheter may include a housing, which may include a distal end configured to couple to a proximal end of a catheter adapter and an inner lumen forming a fluid pathway. The system may also include one or more transmitters, which may be disposed within the housing. The transmitters may be configured to transmit first energy waves along a length of an intravenous catheter at a first frequency, and a portion of the first energy waves that are reflected back from the catheter may be detected by the system. Based on the portion of the first energy waves that are reflected back from the catheter, the transmitters may transmit second energy waves along the length of the catheter at a second frequency, which may be greater than the first frequency and configured to reduce formation of blood clots within the catheter.
