NOTICE: WHILE EVERY EFFORT HAS BEEN MADE IN STATE-OF-THE-ART TECHNIQUES TO OBTAIN THE MAXIMUM COMPATIBILITY OF FUNCTION, STRENGTH, DURABILITY AND COMFORT, THERE IS NO GUARANTEE THAT INJURY WILL BE PREVENTED THROUGH THE USE OF THIS PRODUCT.

INTENDED USER PROFILE

The intended user should be a licensed medical professional, the patient, the patient’s caretaker, or a family member providing assistance. The user should be able to:

Read, understand and be physically capable to perform all the directions, warnings and cautions provided in the information for use.

OPERATING PRINCIPLE

The Cryo/Cuff IC Cold Therapy System provides cold and compression by exchanging chilled pressurized water between the cuff and the cooler intermittently.

INTENDED USE/INDICATIONS

The Cryo/Cuff™ IC Cold Therapy System provides intermittent compression to minimize swelling and pain.

The intended use of the AirCast Cryo/Cuff IC is for the temporary reduction of swelling and pain after surgery or injury. This is a non-sterile prescription device for single patient use to provide localized external application of cold therapy and intermittent compression. This device may not be used for any other purpose

CONTRAINDICATIONS

Raynaud’s or other vasospastic diseases; diabetics; sickle-cell anemia, arteriosclerosis, cryoglobulinemia, hypercoagulable clotting disorders or other peripheral vascular diseases causing ischemia or poor local circulation; compromised local circulation; local tissue infection; cold allergy, cold hypersensitivity, previous cold injury, and paroxysmal cold haemoglobinuria.

WARNING: Before using the Cryo/Cuff™ IC Cold Therapy System, read the enclosed instructions carefully and completely.

APPLICATION INFORMATION

Before applying the Cryo/Cuff, prepare the cooler (Figure 1)

Connect the blue tube to cooler.
Add cold water to line inside cooler.
Fill with ice.
Lay insulation disk on top of ice. Attach cooler lid snugly. Allow five minutes with occasional shaking to chill water.

Always apply EMPTY Cryo/Cuff (Figure 2)

Use only Aircast Cryo/Cuffs and ArcticFlow Cuffs with Aircast Cryo/Cuff IC Unit. Cuff is the Applied Part.
Carefully and completely read instructions supplied with the specific Cryo/Cuff prior to application. Please follow the instructions below to continue cooler preparation.

Fill and pressurize Cryo/Cuff (Figure 3)

To fill cuff: Connect blue tube to the cuff. Raise cooler no more than 15” (38cm) above the cuff for approximately 30 seconds while Cryo/Cuff fills.
To correctly position cooler: Place cooler on stable surface.
The cooler base should be even with the cuff.
NOTE: To AVOID excessive pressure during use, DO NOT raise the cooler higher than 15” (38 cm) above the Cryo/ Cuff.
To turn cooler on: Plug power supply into wall outlet and connect cord to lid.
To turn off the equipment disconnect the power supply.
To refill cooler: When Ice has melted , unplug the cooler and repeat items 1-5 under Step 1.
For specific cuffs, please refer to instructions for installation of each cuff and follow procedure above.

WARNINGS AND CAUTIONS

A licensed health care practitioner must select the length of use and frequency of use depending on individual patients needs. DO NOT use this device if a prescription has not been provided to you or if you do not understated the prescription as this may result in injury.
Follow all precautions necessary to avoid electrical shock, fire, burns, or other personal injury from electrical power by using the device indoors, with dry hands, in a dry location. Keep all electrical connections away from water. Extreme care must be taken when using any cold therapy system. Any cold products may cause injuries, e.g. burns, blisters, frostbite, swelling, discoloration and skin or tissue necrosis if improperly used or monitored.
Patient skin condition checks must occur every 1~2 hours on a routine basis. Caution must be taken by routinely monitoring the patient during use on children, elderly, incapacitated patients, severe cardiovascular diseases, those with decreased skin sensitivity or circulation due to poor nutrition, medications (e.g. beta blocker or epinephrine, narcotics), tobacco and alcohol use. If such monitoring is to occur outside the presence of the licensed healthcare professional, he or she must ensure that the patient or patient caretaker understands how such monitoring is to be conducted.
If redness, itching, numbness, burning, pain or tingling increases, or unusual reactions like blisters, discoloration, swelling, welts, or other changes in skin appearance occur while using this product, consult your medical professional immediately.
DANGER – Risk of explosion if used in the presence of flammable anesthetics or oxygen rich environment.
To reduce the risk of electrical shock, do not disassemble unit. Return to manufacturer per Warranty.
Do not allow fluid to come into contact with the power connection on lid.
Only use power supply provided with unit. Failure to follow instructions could damage the pump, power supply or both.
The product is not suitable for use in contact with foods and beverage.
Dispose cooler and lid according to local, state and federal regulations.
Keep power cord, hose, small parts and packaging materials away from small children and animals. These items pose a risk for suffocation or strangulation.
It could be unsafe to use accessories, detachable parts and materials, or interconnect to other equipment not described in these instructions, or otherwise modify equipment.
Care must be taken when operating this device adjacent to other equipment. Potential
electromagnetic or other interferences could occur to this or other equipment. Try to minimize the interference by not using other electronic equipment in conjunction with this device.
The power supply unit is the mains power disconnect. Do not position the equipment to make access to the disconnect difficult.
It is recommended that at least 20 minutes of cessation should be encouraged between 2 hour long cryotherapy sessions.
When applying the device wrap to the skin, apply a barrier (e.g. cloth or bandage) between the wrap and your skin, and do not wrap it around the area tightly. No part of the wrap should touch the skin for any period of time.
The treatment site should be kept dry. Check for moisture on the barrier between your skin and cold pad. If moisture is present on the barrier, immediately discontinue use of this device.
Ensure to speak with your healthcare provider prior to use if you suffer from Buerger’s disease, suffer from a condition that may decrease your skin sensation, such as peripheral neuropathy, sciatica, stroke or spinal cord injury, if you are taking medication that may negatively impact on peripheral vascular circulation (e.g. beta adrenergic blockers and local epinephrine) or, if you have a history of frostbite or adverse reactions to local cold application.

This device adheres to the following standards: IEC60601-1, IEC60601-1-2, IEC60601-1-6, IEC60601-1-11, IEC62366.

ELECTROMAGNETIC COMPATIBILITY (EMC )

Cryo Cuff IC has been tested and found to comply with the electromagnetic compatibility (EMC) limits for medical devices to IEC 60601-1-2. These limits are designed to provide reasonable protection against harmful interference in a typical medical installation .

CAUTION: Medical electrical equipment requires special precautions regarding EMC and must be installed and operated according to these instructions . It is possible that high levels of radiated or conducted radio-frequency electromagnetic interference (EMI) from portable and mobile RF communications equipment or other strong or nearby radio-frequency sources, could result in performance disruption of the system . Evidence of disruption may include equipment ceasing to operate, or other incorrect functioning. If this occurs, survey the site of disruption, and take the following actions to eliminate the source(s).

Turn equipment in the vicinity off and on to isolate disruptive equipment .
Relocate or reorient interfering equipment.
Increase distance between interfering equipment and your system.
Manage use of frequencies close to the system frequencies.
Remove devices that are highly susceptible to EMI.
Lower power from internal sources within the facility control (such as paging systems).
Label devices susceptible to EMI.
Educate clinical staff to recognize potential EMI-related problems.
Eliminate or reduce EMI with technical solutions (such as shielding).
Restrict use of personal communicators (cell phones, computers) in areas with devices susceptible to EMI .
Share relevant EMI information with others, particularly when evaluating new equipment purchases which may generate EMI.
Purchase medical devices that comply with IEC 60601-1-2 EMC Standards (3 V/meter EMI immunity, limit interference level to 0.0014 V/meter)
