Intraosseous Access Systems and Methods

An adapter for an intraosseous access system, wherein the adapter includes an adapter frame having:

• an adapter socket configured to receive a shaft of an obturator assembly;
• an adapter shaft configured for insertion into a socket of an intraosseous driver;
• and
• a latch mechanism, including a groove engagement member configured for selective displacement into and out of a groove of the shaft of the obturator assembly.

An intraosseous access system, comprising:

• an obturator assembly including an obturator coupling interface having a shaft;
• and
• an intraosseous driver including a driver coupling interface having a chuck, wherein the chuck includes:
• a socket frame member defining a socket configured to receive the shaft;
• and
• a collar rotatable with respect to the socket frame member, wherein rotation of the collar with respect to the socket frame member causes the chuck to radially clamp onto the shaft such that:
• the shaft and chuck co-rotate, and
• removal of the shaft from the chuck is prevented.
