Abstract

A device and method for rapid access to the bone marrow for the infusion of drugs and other fluids into the bone marrow; sampling the bone marrow; and monitoring the physical properties of the blood and bone marrow. These operations may proceed sequentially or simultaneously. A "smart" controller may be utilized to direct or control these operations. An implantable intraosseous needle assembly and various means for injecting, utilizing, and extracting that assembly into a bone containing bone marrow are disclosed.

Claims

1. A method for monitoring blood and bone marrow properties, comprising:

providing an intraosseous needle assembly having a puncturing end and an interconnecting end, an injector, and a receiver;

loading the intraosseous needle assembly into the injector;

attaching the receiver to an implantation site;

aligning the injector with the receiver;

injecting the puncturing end of the needle assembly into a bone by operating the injector;

securing the needle assembly to the receiver;

inserting at least one sensor into the bone marrow via the intraosseous needle assembly; and

monitoring the output of the at least one sensor.
