See below some of the latest research supporting mild hypothermia as a treatment for  concussions:


  • The Zeroº Collar™ should be stored at room temperature and in a dry environment.

  • Remove the Zeroº Collar™ from the package.

  • Lay the Zeroº Collar™ flat on the ground or other hard surfaces with labeled side up.

  • With a closed fist, gently strike the Zeroº Collar™ at the 4 indicated spots top break open the water pouches and activate the cooling process.  If a water pouch does not break open, strike it again slightly harder.  Use of excessive force may cause the collar to leak.

  • Vigorously shake for 10 seconds to activate cooling.

  • Ensure that all 4 compartments are getting cold before applying the Zeroº Collar™.

  •  Zeroº Collar™ is designed to be placed on neck with the two ends meeting at the front of the neck.  A 1.5″ gap between ends is acceptable.

  • The down arrow should be placed at the back of the neck.

  • Secure the Zeroº Collar™ snugly around the neck  with the included velcro strap.  Do not position the Zeroº Collar™ over the mouth or nose

  • Always monitor the patient after application of the collar to ensure that:

    1. The cold is not causing damage (frostbite or ice burn)

    2. Zeroº Collar™ is not too tight that it impairs breathing

    3. Zeroº Collar™ is not too tight to that it affects normal blood flow

  • Discontinue use if you develop an adverse reaction to the application of the Zeroº Collar™.

  • Consult a physician if symptoms worsen or persist.

  • The Zeroº Collar™ is a single use device.  After use dispose of with household waste.


  • Activate the ZEROº Collar™ and check to make sure all compartments become cold. 

  • Do not use a shoe, hammer, or board or other tool to strike the ZEROº Collar™.  Excessive force may cause leaks in the external pouch. If a leak occurs, discard the device immediately.

  • Do not attempt to activate the collar if it is already around a patients neck.

  • Always monitor the patient after placement of the ZEROº Collar™ to ensure that:

    1. The cold is not causing damage such as frostbite or ice burn.

    2. The ZEROº Collar™ is not too tight (that it affects normal blood circulation).

  • Store at room temperature prior to use. Allowable storage range is -18 to 50 degrees C  (0-120 degrees F).

  • The ZEROº Collar™ should be between 10 and 27 degrees C (50-80 degrees F) prior to activating

  • Do not refrigerate or freeze prior to use.

  • The ZEROº Collar™ is a single use device. Do not re-use. Do not simultaneously apply more than one collar to a patient.

  • The patient side (unlabeled side) of the Zeroº Collar™ should be dry and applied to dry skin.  If the device or neck is wet prior to application, rapid cooling may cause damage to skin.

  • CAUTION: To avoid skin or tissue damage a maximum safe period for application of 60 minutes is recommended.

  • The most effective duration of application of the ZEROº Collar™ appears to be 20 to 30 minutes or until the collar no longer provides significant cooling.

  • The ZEROº Collar™ should not be used without direct supervision of anyone who is mentally impaired or incapacitated.

  • The ZEROº Collar™ should not be used on infants.

  • Do not use the ZEROº Collar™ if it is leaking, torn, damaged, or punctured.

  • For external use only. Seek medical attention in case of an accidental exposure to the contents of the ZEROº Collar™. In the event of contact with pack contents, wash affected area with soap and water.

  • If contents are ingested, consult a physician.

  • Keep away from open flame, harsh chemicals, or solvents.

  • Never attempt to use as a heat pack or re-heat in a microwave oven.

  • All directions are considered guidelines and not an attempt to define medical practice.
