  • Patent number: 11324938
    Abstract: The present disclosure is directed to a flexible cap for a medical fitting, such as a luer-lock fitting. The flexible cap includes a cap component defining a top surface, a cylindrical wall extending opposite from the top surface of the cap component, and an inner sealing surface. The cylindrical wall defines a hollow interior configured to receive an internal tapered sealing wall of a male connector of the medical fitting so as to form a seal with an outer surface of the tapered sealing wall. Further, the inner sealing surface of the flexible cap is configured within the hollow interior. Thus, when the tapered sealing wall of the male connector of the medical fitting is received within the hollow interior of the cylindrical wall, the inner sealing surface of the flexible cap seals the fluid passageway of the tapered sealing wall.

  • Patent number: 11253166
    Abstract: This invention relates to a method of catheter and radiating coil location in a human body. In particular, when a radiating coil is used in conjunction with a catheter, a coil locating device can be used to determine the distance the coil is from the device and its depth in the patient's body. A display is provided that shows both a reference image of a portion of a non-subject body and an image of the coil located on the display with reference to the reference image. This is achieved by locating the coil-locating device on a predetermined landmark on the patient's body. The coil and its signal wires can be incorporated into a stylet, guide wire or a catheter. The coil locating device can be orientated towards the head of the patient and for an axis of the device to be aligned with the mid sagittal plane of the patient.
