CRYOGENIC APPARATUS BY DOCTOR VI KOCHENOV Russian patent published in 2012 - IPC A61B18/02 F25B9/02 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to devices for medical cryology. Cryologic apparatus contains thermally isolated reservoir for refrigerant, hermetising cover provided with casing, in which hole is made, main line of refrigerant supply from reservoir and cannel of rising pressure in reservoir with bellmouth for connection of hermetising plug. Under cover casing made is drying cavity from heat-conducting material, connected with heat-insulating cuff with bellmouth and channel of pressure rising, whose projecting into draining cavity part is provided with obliquely cut butt end with direction of cut opposite to hermetising plug. Outlet of channel of pressure rising into reservoir for refrigerant has cone-shaped extension in the thickness of the cover. Around entire main line of refrigerant supply from reservoir coaxially located is channel for refrigerant, hermetically fixed on it when it goes beyond cover casing and connected with radiator on drying cavity wall by means of side capillary channel, whose diameter is smaller than diameter of main line of refrigerant supply, and return part of main line of refrigerant supply is brought under cover casing with possibility of blowing draining cavity wall.

EFFECT: application of invention makes it possible to increase time of continuous work with apparatus and accelerate access to mode with minimal temperature.
