Abstract

A dual balloon comprising an outer sphere and an inner sphere with corresponding conduits placed in the surfaces of the spheres and a connecting trachea being releasable engageable between the conduits and providing an air path from the outside of the outer sphere to the inside of the inner sphere. The inner sphere being able to be free-floating in the outer sphere while remaining inflated and being releasably engageable directly with the outer sphere.

Claims

1. A dual balloon comprising

(a) an outer sphere having first conduit means for allowing gas to flow therethrough, wherein said first conduit means of said outer sphere includes a primary trachea having a primary male portion;

(b) an inner sphere having second conduit means for allowing gas to flow therethrough, wherein said second conduit means of said inner sphere includes a secondary trachea having a secondary receptacle; and

,

(c) a connecting trachea releasably engageable between said first conduit means of said outer sphere and said second conduit means of said inner sphere, said connecting trachea having a primary receptacle and an opposite secondary male portion releaseably engageable with said primary male portion and said secondary receptacle respectively.

2. The dual balloon as claimed in claim 1, wherein:

said primary male portion of said primary trachea having a primary annular ring formed on an outside surface thereof releasably receivable into a corresponding primary annular slot formed on an inner wall of said primary receptacle of said connected trachea; and

said secondary male portion of said connecting trachea having a secondary annular ring formed on an outside surface thereof releasably receivable with a corresponding secondary annular slot formed on an inner wall of said secondary receptacle of said secondary trachea.

3. A dual-balloon comprising:

(a) an outer sphere having first conduit means for allowing gas to flow therethrough;

said first conduit means of said outer sphere including a primary trachea having a primary male portion; and

,

(b) an inner sphere having second conduit means for allowing gas to flow therethrough and being releaseably engageable with said first conduit means of said outer sphere, said second conduit means of said inner sphere including a secondary trachea having a secondary receptacle releaseably engageable with said primary male portion of said primary trachea, said primary male portion of said primary trachea having a primary annular ring formed on an outside surface thereof and releaseably receivable into a corresponding secondary annular slot formed on an inner wall of said secondary receptacle of said secondary trachea.

4. The dual-balloon as claimed in claim 3, further comprising a connecting trachea releasably engageable between said first conduit means of said outer sphere and said second conduit means of said inner sphere.
