SYSTEMS AND METHODS FOR MONITORING AN INJECTION PROCEDURE

摘要

An indicator dilution system includes a catheter configured to deliver an indicator to a patient, an injection device configured to deliver the indicator to the catheter, and a connector coupling the injection device to the catheter. The system also includes one or more sensors configured to acquire measurements from components of the system, which may be used to determine the start and end time of the injection of the indicator to the patient. For example, the one or more sensors may be configured to acquire signals relating to a state of the connector, which may be used to determine whether the connector is in an open state to enable flow of the indicator or in a closed state to reduce flow of the indicator.

1. A sensor assembly comprising:
a connector comprising:
a first end configured to be coupled to an injection device configured to inject a fluid;a second end configured to be coupled to tubing configured to deliver the fluid to a patient such that the connector, when coupled, is between the tubing and the injection device;a lumen extending from the first end to the second end; anda valve assembly configured to enable flow of the fluid through the lumen when the connector is in an open state and to reduce flow of the fluid through the lumen when the connector is in a closed state; and a sensor disposed proximate to the connector and configured to generate a signal relating to whether the connector is in the open state or the closed state.
