CRYODESTRUCTOR Russian patent published in 2015 - IPC A61B18/02 F25D3/10 

FIELD: medicine.

SUBSTANCE: cryodestructor contains a reservoir for a liquid refrigerant with a mouth, a tube for intake of the liquid refrigerant from the reservoir, a tube for the refrigerant supply with a replaceable tip, a tube for discharge of a gas-drop mixture of the refrigerant, a safety valve, a replaceable head, placed on the mouth of the reservoir by means of a thread connection, with the placed on the replaceable head trigger mechanism of the liquid refrigerant supply, which represents a needle valve, the seat of which is connected to the tube for intake of the liquid refrigerant from the reservoir, the needle of which is pressed to the seat by a cylindrical screw spring and is hingedly connected with the trigger, resting on a heat-insulating tube of the trigger mechanism, combined with an intermediate tube for the supply of the refrigerant by a choke of the trigger mechanism. To the trigger mechanism connected is the choke, which connects the heat-insulating tube, the tube for the refrigerant supply, the tube with the changeable head and the tube for the discharge of the refrigerant gas-drop mixture, which through additional chokes is connected to a placed on the replaceable head collector of the refrigerant gas-drop mixture, which represents a reservoir for holding the liquid part of the refrigerant gas-drop mixture and a hole for the output of the gaseous part of the refrigerant in a lid. On the replaceable head placed is the safety valve, which represents a needle valve, in which the needle is pressed to seat, made in the bottom of the safety valve case, by a cylindrical screw spring, the compressing degree of which is regulated by a screw, turned into and turned out along the axis of the needle and spring on the thread of the safety valve case from above.

EFFECT: invention application makes it possible to ensure the high heat-insulation of the body, low consumption of the refrigerant in the stand-byprocess and convenience of application.
