Document Type and Number:
WIPO Patent Application WO2003003908
Kind Code:
A8
Abstract:
An epidural space locating device (10) for locating an epidural space, the device (10) comprising a body section (30) having a first end (32) and a second end (32) and a longitudinal passageway extending therethrough, the first end of which is coupleable to a luer assembly; and a collapsible bellows chamber (20) having one end coupled to the second end (34) of the body section and the other end exposed so as to permit pressure to be exerted thereon by one or more digits of a hand, wherein positive pressure within the bellows chamber (20) maintains the integrity of the shape of the bellows chamber (20) and wherein negative or zero pressure within the bellows chamber (20) facilitates the collapsing of the shape of the bellows chamber (20) thus indicating the locating of the epidural space by a needle (51) that is coupled to the luer assembly; wherein the loss of pressure within the bellows chamber (20) is sensed by the one or more digits of the hand as the shape of the bellows chamber (20) collapses.
