Title:
SYSTEM AND METHOD FOR AUTOMATIC TERMINATION OF FLOW DUE TO NEEDLE DISLODGEMENT
Document Type and Number:
Japanese Patent JP2020110627
Kind Code:
A
Abstract:
To provide a system for automatic termination of flow due to needle dislodgement in which the disconnection of blood vessel connection can be detected and the interruption of flow can be suppressed.SOLUTION: A system 10 and a method for automatic flow termination for fluid delivery are provided each of which includes a housing 12 configured for coupling a fluid delivery tube 16 to a needle 20 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 a first orientation and a closed configuration substantially terminating flow from the fluid delivery tube to the needle when the activation mechanism is in a second orientation.SELECTED DRAWING: Figure 1A
