Description

ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to oxygen generation devices and more particularly to a chemical-generation, portable device usable by a patient or individual at home or in an emergency situation.
2. Description of the Prior Art
Oxygen generation devices are known in the art, however, they are either large, cumbersome, and difficult to use, necessitating that they be used in a medical office or hospital. Alternatively means of a size that can be used by a patient, such as high pressure oxygen cylinders are expensive, difficult to transport, and present an explosive or fire hazard.
SUMMARY OF THE INVENTION
The present invention is a oxygen generating device which comprises: a container having a mouth and a neck surrounding the mouth; a tank which has an annual flange for establishing a gas tight seal between the tank and the neck;
a dome assembly which is engageable with the neck and extends upwardly to define a chamber above the neck (dome chamber); and
means for permitting oxygen generated in the tank to flow into the dome chamber by bubbling through a liquid contained in the dome base;
the dome base having an outlet connection through which oxygen can leave the tank and enter the dome and where at least part of the dome is transparent so as to render the inside thereof visible from the outside of the dome.
An object of the present invention is to provide a device usable by an individual or patient which generates a sufficient supply of oxygen for a wide range of applications. Another object of the present invention is to provide a chemical reaction oxygen generating device which may be refilled by the patient and is reusable or may be a one way, one time delivery system.
Other objects and advantages of the present invention will become apparent from the following description.
