Abstract
The present invention relates to a valve with a residual pressure indicator for a portable oxygen inhalant cylinder, which is a small-sized valve secured to a mouth portion of such portable small cylinder in which the inhalant oxygen is charged in a pressurized state. A residual pressure indicator is assembled in the valve casing of the valve so that a residual amount of compressed oxygen within the cylinder is observed accurately from an outside of the valve casing. Accordingly, the oxygen inhalation device provided with the valve can be safely carried by a patient who has pulmonary disease or respiratory disease or rescuers.
