The Blanket Warming Unit model WB1000 is a revolutionary electrical medical device used
to keep patients warm during anaesthesia and surgery. The device comprises a reusable
controller and disposable, single-use blankets.
The Blanket Warming Unit Model WB1000 is used to maintain normal body temperature
during surgical procedures. The clinical staff who use the device is anaesthetists, anaesthetic
assistants, operating department practitioners and nurses in theatre, the recovery room and
the critical care unit.
The Blanket Warming Unit Model WB1000 is the world’s first closed warming system,
using conduction and radiation warming to prevent and treat preoperative hypothermia. It includes
two primary components: a warming unit and a disposable blanket. The Warming Blanket Unit is
connected to a single-use blanket by an innovative coaxial flexible hose. The coaxial flexible hose
contains an inner and outer hose; warm air from the warming unit passes through the inner hose
and into the blanket. Once the warmed air reaches the blanket, it will move with the flow path of the
blanket, and is then recycled to the warming unit via the outer hose. The closed warming blanket is
disposable and airtight.
To avoid the risk of electric shock, this device must only be connected
to a mains supply with protective earth.
To prevent electromagnetic interference to the unit from other devices,
the other devices must meet EMC requirements.
The Blanket Warming Unit meets medical electronic interference
requirements. If radio frequency interference with other equipment
should occur, connect the unit to a different power source.
Continuously monitor temperature and skin temperature during use on
unconscious patients, elder patients, or pediatric patients.
Risk of electric shock, always unplug power cord before cleaning.
Do NOT use on individuals with circulatory problems unless managed
and monitored by a healthcare professional.
DO NOT place the hose directly on a patient without a blanket.
DO NOT insert the hose underneath the patient, or apply any pressure to
the hose.
DO NOT obstruct vents of the device.
Temperatures will vary according to the room temperature and blanket
sizes.
DO NOT operate if the device is damaged or malfunctioning.
DO NOT position the device in areas in which the appliance plug and
socket are difficult to operate.
Device must only be opened or serviced by qualified personnel such as
certified electricians or certified clinical engineers familiar with repair
practices for servicing medical devices, and in accordance with the
Service Manual.
DO NOT use this unit in any manner other than the purpose or
the operation method described in this instruction manual.
Use only the power cord specified for this product.
DO NOT submerge, spray, pour, or spill any liquid on the unit.
DO NOT operate in wet or moist conditions.
DO NOT drop or hit the product.
Store in a cool dry place.
DO NOT open or disassemble the unit.
No modification of this unit is allowed.
Some national laws restricts this device to sale by or on the order
of a physician.
