Abstract: A fluid extravasation detection device detects the subcutaneous extravasation of fluid from a vein containing an intravenous (IV) catheter. The device includes one or more first temperature sensors for positioning on skin near an entry point of the IV catheter into the vein, and one or more second temperature sensors for positioning on skin near a tip of the subcutaneously located IV catheter. The first and second temperature sensors are operably connected to an electronic thermometer that compares the temperature difference between a first temperature and a second temperature. The first temperature is determined based on temperature detected by at least one of the one or more first temperature sensors. The second temperature is determined based on temperature detected by at least one of the one or more second temperature sensors. An alarm is activated if the difference between the first and second temperatures changes more than a predetermined amount.

Abstract: A patient securing overlay includes a sheet of fabric configured to support a patient's torso on a surgical table. The sheet of fabric includes friction enhancing elements applied to at least a portion of an upper surface. The sheet of fabric is attached near its side edges to two or more side flaps that extend laterally outward from the side edges of the sheet of fabric. Each of the side flaps is attached to the surgical table at two or more attachment points. A distance between adjacent attachment points is greater than a distance between an attachment point and the sheet of fabric in order to naturally create a favorable retaining force vector angle of less than 45° between the attachment point and the sheet of fabric.

Abstract: A concealed vehicular system is provided for a motor vehicle to permit the operator to view or record events occurring inside or outside the vehicle. A miniature camera is concealed within a functional component of the vehicle, such as within a rear-view mirror or a lighting device of the vehicle. The images from the video camera are stored in a recording device, such as a video camera recorder. Alternatively, the images produced by the video camera can be transmitted to a viewing screen, such as a cathode ray tube monitor or liquid crystal diode, within the view of the driver. The concealed video camera housed within a functional component of the vehicle is imperceptible to vandals and thieves, and does not distract from the aesthetics of the vehicle.
