Abstract
An epidural space locating device for locating an epidural space, the device comprising a body section having a first end and a second end and a longitudinal passageway extending therethrough, the first end of which is coupleable to a luer assembly; and a collapsible bellows chamber having one end coupled to the second end 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 maintains the integrity of the shape of the bellows chamber and wherein negative or zero pressure within the bellows chamber facilitates the collapsing of the shape of the bellows chamber thus indicating the locating of the epidural space by a needle that is coupled to the luer assembly; wherein the loss of pressure within the bellows chamber is sensed by the one or more digits of the hand as the shape of the bellows chamber collapses.
