CORPORATE DESCRIPTION: 

Avox Systems has manufactured instruments to measure blood oxygen since 1976. At its headquarters in San Antonio, Texas, the company is developing its proprietary light-scattering technology into a series of clinical instruments to serve various markets including cardiology, intensive care, and emergency medicine. 

The company's unique, new technology enables its instruments to make spectrophometric measurements directly in unaltered whole blood without hemolysis or other sample preparation. 

Because AVOXimeters do not need the pumps, plumbing and hemolyzers employed by conventional co-oximeters, they are faster and less expensive, and they require almost no maintenance. 

The AVOXimeter 1000, released in 1993, is already the oximeter of choice in cardiac catheterization labs in leading US hospitals. In 1996, the company introduced the AVOXimeter 4000, the world's first whole-blood co-oximeter, and established itself as the international leader in this field.
