  • Gas removal in an intravenous fluid delivery system
    Patent number: 7547295
    Abstract: An active gas removal system is provided to remove air or gas bubbles from an intravenous fluid prior to infusion into the patient. The system detects the level of liquid in a drip chamber and occludes a downstream valve to the patient, thereby increasing pressure in the drip chamber sufficient to open a vent valve and release gas therein.

  • Capacitor-based gas detection in an intravenous fluid delivery system
    Patent number: 7377148
    Abstract: An air or gas bubble detection system detects the presence of liquid in intravenous (IV) tubing. By detecting the presence of liquid rather than gas, false alarms due to micro bubbles or small air gaps between the sensor and the tubing are avoided.

  • Medical fluid warming system
    Patent number: 7158719
    Abstract: An improved inline intravenous fluid warming device. In one embodiment, the device includes a resistive film heater that is thermally coupled to a body having a serpentine fluid path extending therethrough. The film heater is coupled to the body via a first layer that is a thermally conductive and electrically insulative and a second layer that is thermally conductive. In another embodiment first and second resistive film heaters are employed to support either line power or battery powered operation.
