Summary:A device for locating an epidural space. The device includes a connector for forming a hermetically sealed connection with a needle. An air vessel is formed by an air tank, a diaphragm, and a space in the needle when the needle is attached to the connector. The device includes a pressure sensor configured to detect the air pressure in the air vessel. An actuator is coupled to a switch and positioned adjacent to the diaphragm to compress the diaphragm when the switch is actuated by a user causing a reduction in volume in the air vessel. A circuit coupled to the pressure sensor and to an alarm detects a signal indicative of the air pressure sensed by the pressure sensor. The circuit compares the signal to a threshold and outputs a first state to the alarm when the pressure is above the threshold, and outputs a second state to the alarm when the pressure falls below the threshold.
