COOLANT DEVICE

摘要

A device, for use in the treatment of soft tissue injuries, delivers a refrigerant foam comprising a matrix of a topically acceptable material such as a paraffin wax, and a refrigerant as a foaming agent for the wax. Preferably, a mixture of different fluorinated hydrocarbons such as dichlorodifluoromethane, trichloromonofluoromethane and dichhlorotetrafluorethane is used as refrigerant. An adhesion-promoting agent such as glycerine may first be applied to the site of the injury to assist in ensuring that the refrigerant foam remains in intimate contact with the injured tissue.
