2081671 9215256 PCTABS00016 The present invention relates to a method and apparatus for locating anatomical cavities such as the epidural space. The puncture will be made on the basis of the loss of resistance technique with a seringe (12). The tapping is facilitated by taking some measurements in the operation region (15) and by the emission of acoustic and visual warning signals, as well as by the provision of data displayed on a screen (16), all of which quantify and corroborate the tactile feelings of the operator, influencing the operator's work and allowing the operator to make proximal trials which are not harmful or damaging, and to be extremely sure that the cavity has been reached. The method is applicable independently of the pressure characteristics of the space to be detected, and uses a conventional needle, which also makes an apprenticeship possible in optimal safety conditions.
