Abstract
A system for the recovery of expanded refrigerant from a cryotreatment system for storage and disposal may generally include first fluid flow path having a first compressor and a fluid recovery reservoir, and a closed-loop second fluid flow path having a thermal exchange device that is in thermal communication with the fluid recovery reservoir, a second compressor, and a condenser. The first fluid flow path may include a primary refrigerant from a cryotreatment system and the closed-loop second fluid flow path may contain a secondary refrigerant for cooling the primary refrigerant within the fluid recovery reservoir. The refrigerant recovery conduit may be in fluid communication with both the cryotreatment system and a medical facility scavenging system. The refrigerant recovery conduit and the cryotreatment system may be located within the same cryotreatment console.
