Abstract

A handheld cryoanesthesia or analgesia device for cooling a target area on cutaneous membranes, mucous membranes, and tissue of the mucocutaneous zone having an elongated body and a thermoelectric cooling system disposed within the elongated body. The thermoelectric cooling system is configured to physically contact and thermally couple the target area of the cutaneous membranes, mucous membranes, and tissue of the mucocutaneous zone to induce cryoanesthesia or analgesia. The thermoelectric cooling system includes a thermally-conductive cold tip, a thermally-conductive cooling power concentrator thermally coupled to the cold tip, at least one Peltier unit module thermally coupled to the cooling power concentrator, a heatsink thermally coupled to at least one Peltier unit module, a power source, at least one thermal sensor, and a controller operably outputting a control signal to the Peltier unit module to maintain a predetermined temperature.
