An epidural space locating device is described, comprising a handle with a proximal end and a distal end; a hollow distal chamber attached to the handle distal end and being provided with a distal connector where a spinal needle is received to be introduced in the patient's body, such that there is a fluid connection between the spinal needle and the distal chamber; the device also comprises a plunger running within the distal chamber from a starting position to a final position when there is a pressure loss within the distal chamber due to the spinal needle has reached the epidural space; the plunger is secured before using the device, which emits a warning signal at the time the epidural space has been reached. |
