  • Publication number: 20210402085
    Abstract: An insertion device to assist in accessing an access port that has been subcutaneously implanted in the body of a patient is disclosed. The implanted access port is accessed by a needle of a needle assembly, such as a needle-based infusion set. The insertion device may include a body having a stabilizing portion and a guide portion. The stabilizing portion stabilizes a position of the implanted access port when the body is placed on the skin of the patient atop the implanted access port. The guide portion is designed to guide a needle of the needle assembly along a predetermined path such that the needle transcutaneously pierces a septum of the implanted access port.

  • Patent number: 10820885
    Abstract: An ultrasound imaging device including the ability to determine when a component, such as a removable probe cap, is attached to a portion of an ultrasound probe. Such a cap is employed in one embodiment to act as a spacer component to provide a standoff for the probe head. Detection of probe cap attachment to the ultrasound probe enables the resultant ultrasound image to be adjusted automatically by the ultrasound imaging system. In one embodiment, an ultrasound imaging system comprises an ultrasound probe, a cap or other component that is attachable to the probe, and a component attachment detection system for detecting attachment of the component to the probe. Once the cap is detected, an aspect of an ultrasound image produced by the imaging system is modified, such as cropping the image to remove undesired portions of the cap, such as the spacer component.
