摘要:
A system and kit for using a source of low-pressure refrigerant for a cryotherapy procedure and for subcooling a cryotherapy refrigerant. The system may generally include a fluid reservoir and a fluid flow path in thermal exchange with the fluid reservoir, the fluid flow path including a first thermal exchange device in thermal exchange with the fluid reservoir, a compressor in fluid communication with the first thermal exchange device, a condenser, a reversing valve located between the compressor and the condenser, a second thermal exchange device located between the reversing valve and the compressor, and an expansion valve located between the condenser and the thermal exchange device. The third thermal exchange device may be configured to be in fluid communication with the cryotherapy console and configured to place a secondary refrigerant within the first fluid flow path in thermal communication with a secondary refrigerant of the cryotherapy system.
