An intraosseous injection device comprises a tool having a distal portion, a proximal portion, and a solution dispensing opening. The distal portion of the tool has one or more cutting surfaces. The tool can be configured to be coupled with a protective carrier. The tool is configured to be rotatably coupled to a tool actuation mechanism. A housing has a distal end and a proximal end. The housing is configured to releasably receive a solution cartridge containing a solution. A solution dispensing mechanism is configured to dispense solution from the solution cartridge. A gripping member is configured to grip a proximal portion of the tool. A rotation device is configured to rotate the gripping member and thereby rotate the tool about an axis. The device is configured such that 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.
