Abstract
An intraosseous device having an elongated shaft and handle with a syringe attached to the shaft is disclosed. The syringe can be filled with an intraosseous liquid suspension which is made of a hydroxyapatite, a carbonated apatite, a calcium ion source, and a hormone mixture. The shaft includes a frusto-conical connector for releasable interconnection with cortical bone, and the handle facilitates turning the shaft to interconnect it to the bone.
Claims9
An intraosseous injection device comprising:
- (a) an elongated shaft having a proximal and distal end and a through bore beginning at the proximal end and terminating at the distal end in a frusto-conical connector portion for releasable interconnection with cortical bone;
- (b) a handle means associated with said elongated shaft at the proximal end for turning said shaft so that said shaft is releasably interconnected with the cortical bone;
- and
- (c) a syringe for the injection of an intraosseous liquid suspension into the through bore in said elongated shaft wherein said syringe is connected to said shaft.

An intraosseous injection device comprising:
- (a) an elongated shaft having a proximal and distal end and a through bore beginning at the proximal end and terminating at the distal end in a frusto-conical connector portion for releasable interconnection with cortical bone, wherein the proximal end of said elongated shaft terminates in a hub having a recessed portion for the releasable engagement of manipulatable parts comprising a needle carrying hub having a vented double hollow needle and a proximal chamber for operative interengagement with a syringe;
- (b) a handle means associated with said elongated shaft at the proximal end for turning said shaft so that said shaft is releasably interconnected with cortical bone;
- and
- (c) a syringe operatively interengaged with the hub of said elongated shaft for the injection of an intraosseous liquid suspension into the through bore in said elongated shaft.
