About OHK Medical Devices

Emergency Auto-Transfusion Tourniquet – HemaShock®by OHK 
is used to squeeze blood out of the legs (also arms if needed) and block reentry of arterial blood flow into those
limbs.
This can be done quickly by a single caregiver (Paramedic, Medic, Nurse, Physician) even during transport.
The HemaShock® is indicated for use in patients who have very low systolic blood pressure (i.e. less than 80 mm Hg) due
to Hemodynamic Shock or Circulatory (Cardiac) Arrest.
