Devices for dispensing a hydrofluoroolefin vapocoolant composition as an aerosol

Abstract

A device for dispensing a hydrofluoroolefin vapocoolant composition as an aerosol is disclosed. The device comprises an aerosol-dispensing container comprising an internal chamber, a valve, a dispensing hole, and an actuator. The device also comprises a hydrofluoroolefin vapocoolant composition comprising HCFO-1233zd at 70% to 100% (weight/weight) and, optionally, HFO-1234ze in at 0% to 30% (weight/weight). The hydrofluoroolefin vapocoolant composition is stored within the internal chamber. The aerosol-dispensing container is configured so that depressing the actuator reversibly opens the valve to allow the hydrofluoroolefin vapocoolant composition to flow from the internal chamber, past the valve, and through the dispensing hole, thereby dispensing the hydrofluoroolefin vapocoolant composition from the aerosol-dispensing container. A method of treating pain and/or swelling of a tissue of a patient by use of the device also is disclosed. The method comprises a step of dispensing the hydrofluoroolefin vapocoolant composition from the device onto the tissue of the patient.
