Peripheral venous catheter assemblies with sensors and related methods

A catheter system comprising:

• a catheter hub comprising a hub body having an exterior and an interior and an open proximal end;
• a catheter tube having a lumen attached to the catheter hub;
• a connector housing having an inlet and an outlet aligned along a lengthwise axis attached to the proximal end of the hub body;
• a movable piston having a head section, a neck section, and a body section located inside the connector housing and being configured to compress and expand to control flow through the inlet of the connector housing;
• a sensor extending out of the outlet of the connector housing and into the hub body for sensing status of the catheter hub or for monitoring patient conditions;
• at least one of a smart device and a Cloud server for collecting data sensed by the sensor;
• and
• a computational core mounted around an exterior of the connector housing, the computational core having a body with a power supply and circuitries mounted to the body.
