Abstract
Systems and methods for automatic flow termination for fluid delivery, including a housing configured for coupling a fluid delivery tube to a needle configured for subcutaneous delivery of fluid within a tissue of a patient and a spring-loaded activation mechanism having a first orientation corresponding to a condition where the housing is disposed substantially adjacent to the tissue and the needle lodged within the tissue and a second orientation corresponding to a condition where the housing is disposed away from the tissue or the needle being dislodged from the tissue. A flow termination mechanism is coupled to the activation mechanism and having an open configuration allowing flow from the fluid delivery tube to the needle when the activation mechanism is in the first orientation and a closed configuration substantially terminating flow from the fluid delivery tube to the needle when the activation mechanism is in the second orientation.
