Cleaning
Spot Vital Signs
Occasionally wipe the Spot Vital Signs, as necessary, with a cloth slightly dampened with
appropriately diluted, non-staining disinfectant solution. Use either 70% isopropyl alcohol,
10% chlorine bleach solution, or mild detergent in warm water. Never immerse the Spot
Vital Signs in any type of fluid.
Blood Pressure Cuff
Clean the blood pressure cuff with a damp cloth, or wash in water with soap or detergent.
Before washing the blood pressure cuff, remove the tube fitting(s), close off tubes with
plugs (available as accessory 5082-163) and place the hook and loop fasteners in the
closed position. After washing, allow the blood pressure cuff to air dry. Re-assemble the
tube fitting(s).
Disinfection: You may use glutaraldehyde-type liquid disinfectants on the durable blood
pressure cuff. Prolonged use of these disinfectants at full strength may cause
discoloration of the white blood pressure cuff markings.
Sterilization: Do not use steam or heat to sterilize the blood pressure cuff or pressure
hose. If necessary, use gas sterilization.
Caution Do not use ethyl alcohol to clean the Spot Vital Signs device.
Caution Do not sterilize or autoclave the Spot Vital Signs.
Note
Prevent water or other fluids from entering any connectors. Should this occur, dry
the connectors with warm air. Check all measurement functions for proper
operation.
Caution Do not press with a hot iron.
