Abstract
A device is described that uniformly cools a surface to a specified temperature using a mist of cryogenic fluid. The device comprises a cryogenic fluid reservoir, a valve for controllably releasing the fluid through an atomizing nozzle, a non-contact temperature sensor, and a control unit to display the measured temperature and optionally pre-set the desired surface temperature and control the valve. The application of mist can be controlled manually or electronically. This invention provides a portable tool for safely cooling skin for dermatological applications.
Claims39
A device for cooling a surface to a desired temperature, comprising:
- a reservoir for a cryogenic fluid having a valve to controllably release the fluid from the reservoir;
- means to form a mist of the fluid released from the reservoir and to direct the mist at the surface to cool an area;
- a non-contact temperature sensor that measures the temperature of the surface within the cooled area;
- and
- a control unit connected to the temperature sensor that activates the temperature sensor, wherein the control unit can be programmed by a user with the desired final temperature.
A method for cooling a surface to a desired temperature, comprising:
- directing a mist of a cryogenic fluid at the surface to cool an area;
- activating a non-contact temperature sensor using a control unit;
- measuring the temperature of the surface within the cooled area with the temperature sensor;
- and
- stopping the mist when the measured temperature reaches the desired temperature.
