Disposable anesthesia delivery system

摘要

An intraosseous delivery apparatus having a drill coupling member and a drilling needle member. The drill coupling member includes a shaft, an open housing provided at one end of the shaft, a connecting portion provided at an opposite end of the shaft for establishing a connection to a conventional dental drill, and an anticlog needle extending from the shaft through the open housing. The drilling needle member includes a drilling needle housing and a hollow drilling needle shaft extending therefrom. The drilling needle member is adapted to be removably engaged with the drill coupling member such that the drilling needle housing of the drilling needle member is inserted into the open housing of the drill coupling member and such that the anticlog needle of the drill coupling member is inserted into the hollow drilling needle shaft of the drilling needle member. The drilling needle housing of the drilling needle member and the open 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. The 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.
