Abstract

A portable and passive safety intraosseous device to allow for direct introduction of medications, etc., within the intermedullary space of a subject patient'"'"'s bone or, if needed, the removal of certain substances from such a subject patient'"'"'s bone. Such a device permits direct drilling and placement of a cannula within the subject bone with access external to the subject patient'"'"'s skin, permitting, as well, connection of a tube for such introduction/removal purposes. The ability to provide a passive safety unit allows for facilitated utilization in, for instance, emergency situations with the entire device provided for utilization thereof. The device includes a drilling component with a permanently attached stylet and a removable cannula, a power supply for a single drilling operation, a mechanism to draw the stylet back into the drill component after use and disengagement from the cannula, and an automatic closure that activates with the separation of the cannula.

Claims

1. A cannula implement for utilization with a complementarily configured stylet within an intraosseous drill device for introduction of substances within the intermedullary space of a patient'"'"'s bone, wherein said cannula implement comprises a needle portion on one end and a hub portion on the opposite end, wherein said hub portion includes a recessed opening leading to a bore for substance introduction through said needle portion wherein said recessed opening further includes suitable configured attachment implements therein for connection and disengagement between said cannula and said stylet on demand as well as between a transfer line for delivery of said substances on demand, wherein no extensions from said hub are present for connections between said stylet or said transfer line.
