The Paxman Scalp Cooling System (PSCS) is a compact, mobile refrigeration unit that has been tested to IEC 60601 safety standards for medical devices. The unit circulates a refrigerated liquid coolant, at low pressure, through a special cooling cap that is positioned on the patient’s head. The circulation of the refrigerated coolant through the cap extracts heat from the patient’s scalp and maintains it at the optimum temperature for scalp cooling. There are two versions of the device. One is for single patient use, PSCS1, the other is for two patient use, PSCS2.
An assembly of mains electricity (AC-powered) devices intended to reduce scalp hair loss associated with intravenous chemotherapy treatment by cooling the scalp to cause vasoconstriction and reduction of chemotherapy drug uptake by the follicular cells. It consists of a control unit which pumps a cooling agent to a head-worn cap containing coolant channels and temperature monitoring sensors. An insulating cap (e.g., neoprene) may be worn over the cooling cap to secure it and prevent condensation.
