OSAKA (Kyodo) Kawasaki Engineering Co. launched sales Thursday of a fatigue-treatment device that generates high levels of oxygen in the blood in a high-pressure environment.

The Dream Plus device carries a price tag of 3.8 million yen. The Kobe-based subsidiary of Kawasaki Heavy Industries Ltd. said it aims to sell the product to gyms and beauty salons.

The cylindrical machine is modeled on oxygen hyperbaric chambers used in hospitals for treatment of hypoxia, which can be caused by gas poisoning. It measures 2 meters in length and 65 cm in diameter and is made from polyurethane and nylon fibers.

Users will lie in the chamber for 50 minutes at a time, with the air pressure inside about 1.3 times that of atmospheric pressure. The oxygen in the blood increases in proportion to the air pressure, the company said.

Kawasaki Engineering said similar devices are used by British soccer star David Beckham as well as Japanese professional baseball and soccer players.
