LOCAL CRYOANESTHESIA DEVICE, METHOD OF CONTROLLING LOCAL CRYOANESTHESIA DEVICE, AND COOLING TEMPERATURE REGULATOR OF LOCAL CRYOANESTHESIA DEVICE

WIPO Patent Application WO/2018/093141

A3

The present invention provides a local cryoanesthesia device which sprays a coolant on a treatment site to cryoanesthetize the treatment site so as to be able to more rapidly and accurately regulate the temperature of the coolant sprayed on the treatment site. The local cryoanesthesia device comprises: a housing which forms an outward form and from which the coolant is sprayed; a spraying unit which is installed in the housing to spray the coolant; a cooling temperature regulator which is connected to the spraying unit to apply thermal energy to the sprayed coolant for temperature regulation; and a control unit which is connected to the cooling temperature regulator to control the cooling temperature regulator. Accordingly, the cryoanesthesia device has the functions of measuring and regulating the temperature of the coolant, and is thus capable of applying the coolant to the treatment site within a safe temperature range according to the purpose of treatment, thereby enabling a desired treatment purpose such as local anesthesia to be safely and rapidly accomplished without side effects such as cytoclasis.
