      OHK Medical Devices

      OHK Medical Devices is a privately held Medical Devices Company, manufacturing and selling innovative products for orthopedic surgery, vascular surgery, and emergency medicine. Its core patent-protected technology is a line of single-use devices for quick and effective displacement of blood from the limbs and blocking its re-entry.

      OHK’s surgical products – the HemaClear® – are sterile and are widely used to create a bloodless surgical field. Over 1 million procedures have been performed with the HemaClear® on 5 continents, with excellent acceptance by users and an impeccable safety track record.

      HemaClear® is endorsed by key opinion leaders in adult and pediatric medical centers worldwide.

      OHK recently launched its EED™ product line for use in Emergency Medicine, where it is used to auto-transfuse a patient’s own blood from the limbs into central circulation, during severe shock and during Cardio Pulmonary Resuscitation (CPR).

      HemaClear® Single-Use Surgical Tourniquets uniquely combines two key functions:

      • Shifting blood from an extremity (exsanguination)
      • Creating an effective arterial block (tourniquet)

      HemaClear® Tourniquets enable OR personnel to obtain a bloodless surgical field within seconds, without the need for any additional equipment.

      Studies have shown that the use of HemaClear® Sterile Tourniquets dramatically reduces post-procedure complications.

      HemaClear® Tourniquets are available in a wide range of sizes, for both upper and lower extremities, and they fit any patient – from infants to obese adults.

      The narrow footprint of the device provides the surgeon with the broadest surgical field, promoting an improved surgical exposure.

      HemaClear® is simple to use and reduces OR clutter.

      Once applied, HemaClear® Tourniquets provide a 100% Sterile surgical field.
