First Claim
1. A device for intraosseous delivery of solutions, comprising:
- a housing that receives a solution cartridge having a penetrable seal on one end thereof, the solution cartridge holding a solution therein;
a gripping device having an open position to receive a needle and having a closed position to grip the needle, the needle having a hollow bore extending therethrough from a proximal end to a distal end thereof, the gripping device holding the needle with the proximal end of the needle in the solution and with the distal end of the needle exposed for engagement with a material to be drilled;
a rotating mechanism that rotates the gripping device to rotate the needle; and
a dispensing mechanism that applies pressure to the solution within the solution cartridge to force the solution from the solution cartridge through the hollow bore of the needle to eject the solution from the distal end of the needle.

Abstract
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.
