An intraosseous injection device includes a tool having a distal portion,
a proximal portion, and a solution dispensing opening. The distal portion
has one or more cutting surfaces. The tool can be coupled with a
protective carrier. The tool can be rotatably coupled to a tool actuation
mechanism. A housing has a distal end and a proximal end. The housing
releasably receives a solution cartridge containing a solution. A
solution dispensing mechanism dispenses solution from the solution
cartridge. A gripping member grips a proximal portion of the tool. A
rotation device rotates the gripping member and thereby rotates the tool
about an axis. The proximal portion of the tool connects directly to the
solution cartridge such that solution from the cartridge can be delivered
through the solution dispensing opening. The tool is configured to rotate
relative to the solution cartridge.
