Disposable anesthesia delivery system

An intraosseous delivery method comprising the steps of:

• removably coupling a housing and a drill, said housing having a drilling needle shaft extending therefrom, and said drilling needle shaft having a passageway provided therein which communicates with a delivery opening provided in the housing;
• using the drill to provide a bone penetration force for causing the drilling needle shaft to drill a hole directly in a bone;
• removing the drill from the housing;
• liquid tightly engaging a cap with the housing after removing the drill from the housing, said cap including a nozzle to which a flex tube is engageable, and said nozzle communicating with the delivery opening in the housing when the cap and the housing are engaged so as to establish a communication path from the flex tube through the nozzle into the housing and through the passageway provided in the drilling needle shaft directly into the hole drilled in the bone;
• and
• introducing a fluid into the delivery opening in the housing and through the passageway provided in the drilling needle shaft so as to directly deliver the fluid into the hole drilled in the bone.

An intraosseous delivery apparatus comprising:

• a drill coupling member including a shaft portion, a housing provided at one end portion of the shaft portion, a connecting portion provided at an opposite end of the shaft portion for establishing a connection to a conventional dental drill, and a hollow anticlog needle extending from the shaft portion through the housing;
• and
• a drilling needle member including a drilling needle housing and a hollow drilling needle shaft extending from the drilling needle housing, said drilling needle member being adapted to be removably engaged with the drill coupling member by removably engaging the drilling needle housing of the drilling needle member with the housing of the drill coupling member, such that the hollow anticlog needle of the drill coupling member is inserted into the hollow drilling needle shaft of the drilling needle member;
• wherein the drilling needle housing of the drilling needle member and the housing of the drill coupling member are shaped so that a bone penetration force may be applied therebetween for drilling a hole in a bone to insert the drilling needle member therein when the drilling needle member and the drill coupling member are engaged;
• and
• wherein said hollow drilling needle shaft is adapted to receive a needle of a syringe when the drilling needle member and the drill coupling member are disengaged and the drilling needle member is left inserted in the hole drilled in the bone, so that a reusable communication path through the hollow drilling needle shaft directly into the hole drilled in the bone is established through which fluid may be repeatedly injected.

An intraosseous delivery method comprising the steps of:

• removably coupling a drill coupling member to a drill, said drill coupling member including a shaft portion, a housing provided at one end of the shaft portion, a connecting portion provided at an opposite end of the shaft portion, and a hollow anticlog needle extending from the shaft portion through the housing;
• and
• removably engaging a drilling needle member with the drill coupling member such that a drilling needle housing of the drilling needle member is non-rotatably coupled to the housing of the drill coupling member and such that the hollow anticlog needle of the drill coupling member is inserted into a hollow drilling needle shaft extending from the drilling needle housing of the drilling needle member;
• applying a bone penetration force from the drill via the drill coupling member to the drilling needle housing of the drilling needle member so that the hollow drilling needle shaft with the hollow anticlog needle inserted therein drills a hole in a bone;
• disengaging the drill coupling member from the drilling needle member in a manner such that the hollow drilling needle shaft is left inserted in the hole drilled in the bone;
• inserting a needle of a syringe into the hollow drilling needle shaft left inserted in the hole drilled in the bone;
• and
• introducing a fluid from the syringe directly into the hole drilled in the bone via the hollow drilling needle shaft.
