DEVICE FOR INTRAOSSEOUS INJECTION OF LIQUID SUBSTANCES

摘要

A device for intraosseous injection of liquid substances, wherein the outside tube having a male thread on its end introducible onto osseous tissue and a head at its opposite end, is movably fitted onto the hollow inside tube which has a pointed tip at its end introducible into osseous tissue, oper-end injection holes being provided in a close proximity to said pointed tip. Besides, the outside tube and the tip itself have on their sides facing each other claws or jags directed towards one another and adapted, when the device is being screwed into osseous tissue, to get in engagement with one another so as to close said injection holes and thus prevent them from being clogged with osseous tissue.
