CWS4000 Cocoon Warming System Operator Manual

INTRODUCTION This device should only be operated under the guidance/supervision of qualified medical/nursing personnel or other paramedical staff trained in the use of Convective Patient Warming Systems. It is a pre-requisite for all persons using this medical device to understand the information contained in this Manual. Read and understand this Manual and all precautions prior to operating the Cocoon Convective Warming System. When used with Care Essentials patient warming blankets, the Care Essentials CWS4000 provides a continuous method of warming patients intended for preventing and treating hypothermia. The Cocoon Convective Warming System consists of a CWS4000 and a warming blanket. A connecting hose conducts heated air from the CWS4000 to the warming blanket.

Figure 1 Convective Warming System Care Essentials recommend that a program of regular routine maintenance, electrical safety and performance inspections be instituted for the CWS4000 as described in Section 5.3 below. The CWS4000 is a mains-powered, microprocessor-controlled device that delivers a continuous flow of temperature-controlled air through a flexible hose to the warming blanket. The temperature of the air delivered to the blanket can be set to one of six settings ambient, 34oC, 37oC, 40oC, 43oC, or 46oC. When a temperature of 46oC is selected, the setting automatically drops to 43oC after 10 minutes. The CWS4000 will not cool the air delivered to the blanket below the ambient temperature of the room. Air is drawn into the sides of the CWS4000 and passes through a bacteriological HEPA filter. The CWS4000 includes a number of over-temperature prevention systems and in a temperature fault condition it automatically shuts down and signals an alarm. This Manual presents all the relevant operation information for the Care Essentials CWS4000 Cocoon Warming System. This information is intended for the fair purposes of operation and maintenance of the CWS4000. It is provided as Commercial-In-Confidence material to the Care Essentials Distributor or CWS4000 owner and shall not be made available to any other organization or person without the specific written permission of Care Essentials.
