摘要：
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.
