Vascular access devices for monitoring patient health

A system comprising:

• a vascular access device comprising:
• a reservoir component comprising:
• a reservoir body defining an interior chamber configured to receive fluid therein;
• a self-sealing septum covering the chamber;
• and
• an outlet port in fluid communication with the chamber, the outlet port configured to be mated to a catheter;
• a monitoring device removably couplable to the vascular access device, the monitoring device comprising:
• an electronics component comprising:
• one or more sensing elements configured to obtain physiological measurements;
• a wireless communication module;
• and
• a battery in electrical communication with the sensing element(s) and the wireless communications module;
• and
• a flexible housing configured to enclose the electronics component therein and to removably receive the vascular access device, the flexible housing including one or more topographical features to facilitate localization via palpation, wherein the flexible housing defines a first region for housing the electronics component and a second region for receiving the reservoir component, wherein the first region and the second region are arranged such that the electronics component is maintained separate from the reservoir component when the vascular access device is received in the flexible housing.
