History
The Sea-Long Medical hood (Duke Hood) was first introduced in 1985. This original hood was all vinyl with a zipper across the front for air breaks and was attached by tape only. In 1986, the introduction of the original neckseal and hood, similar to the current product designs on the market now, was introduced by Clark (Shorty) H. Long, an ex-Navy diver and the original owner who invented the hood assembly. Mr. Long worked with the staff at Giessenger Health Systems which is part of Penn State University, to medically evaluate the performance of the hood assembly. Clark Long and Gerald Cox, the current President and owner of Sea-Long, developed the original neckseal design.

This design, which was introduced in 1986, is now the industry standard for the hood and neckseal. The original hood assembly had a hand dipped latex neckseal and manufactured with the zipper in the hood for airbreaks. For a short period of time the zipper was a part of the hood until the neckseal design was proven effective for air breaks by separating the neckseal and hood during the dive. In 1992 the visor hood was introduced. This was a significant improvement for patient comfort and reduced claustrophobic issues.

There have been various changes over the years. In 2001, the Series 500, 100% latex-free hood assembly was introduced to the market. This is the most versatile hood on the market today with many options for various uses and applications. Both of our hood assemblies are FDA cleared devices and are CE marked for sales in Europe.

The retirement of the worlds first Oxygen Hood and Neckseal design, the Series 300 that was developed by Sea-Long Medical Systems in 1985 has retired in December of 2007. This product served the indisutry well and changed the method of delivering oxygen to the patient in a multiplace chamber around the world.
