Abstract

Abstract An improved gastrostomy tube comprising a main conduit having a slanted outlet port at a lower end. A balloon is affixed to the lower end of the main conduit and about the slanted outlet port. A valve stem is connected at an angle to an upper end of the main conduit. A one-way valve is affixed to an upper end of the valve stem. An elongated filler pipe extends from the one-way valve through the valve stem and down through a wall of said main conduit into the balloon. A fluid, such as a saline solution/air, can be forced through the one-way valve and the elongated filler pipe, to inflate the balloon into a kidney shape, thereby making it easier and safer to insert the lower end of the main conduit through an opening in a stomach from an opening in an external surface of a body of a person.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 361 words
An improved gastrostomy tube comprising: a) a main conduit consisting of a hollow cylindrical upright channel having an upper end and a lower end with a slanted outlet port at said lower end; b) a balloon affixed to said lower end of said main conduit enclosing said slanted outlet port leaving said slanted outlet port within said balloon, said balloon being kidney shaped when inflated and having an opening aligned and coextensive with said slanted outlet port; c) a valve stem connected at an angle to said upper end of said main conduit: d) a one-way valve affixed to an upper end of said valve stem; e) an elongated filler pipe extending from said one-way valve through said valve stem and down through a wall of said main conduit into said balloon, so that a fluid can be forced through said one-way valve and said elongated filler pipe to inflate said balloon, thereby making it easier and safer to insert said lower end of said main conduit through an opening in a stomach from an opening in an external surface of a body of a person; f) a primary conduit consisting of a hollow cylindrical upright channel having an inlet port at one end and fluidly connected at the opposite end to said upper end of said main conduit to permit supplementary nutrition to be inserted into said inlet port of said primary conduit to travel through said main conduit and out of said slanted outlet port and into the stomach of the person; g) a secondary conduit consisting of a hollow cylindrical branch channel having an inlet port at one end and fluidly connected at the opposite end to the upper end of said main conduit to permit the insertion of medication into the inlet port of said secondary conduit to travel through said main conduit and out of said slanted outlet port and into the stomach of the person; and h) stop member means integrally formed in the outer surface of said main conduit directly below the juncture of said valve stem, said primary conduit, and said secondary conduit to provide a fixed finger grip on said gastrostomy tube.
Claim 2
Dependent Claim 361 words
An improved gastrostomy tube comprising: a) a main conduit consisting of a hollow cylindrical upright channel having an upper end and a lower end with a slanted outlet port at said lower end; b) a balloon affixed to said lower end of said main conduit enclosing said slanted outlet port leaving said slanted outlet port within said balloon, said balloon being kidney shaped when inflated and having an opening aligned and coextensive with said slanted outlet port; c) a valve stem connected at an angle to said upper end of said main conduit: d) a one-way valve affixed to an upper end of said valve stem; e) an elongated filler pipe extending from said one-way valve through said valve stem and down through a wall of said main conduit into said balloon, so that a fluid can be forced through said one-way valve and said elongated filler pipe to inflate said balloon, thereby making it easier and safer to insert said lower end of said main conduit through an opening in a stomach from an opening in an external surface of a body of a person; f) a primary conduit consisting of a hollow cylindrical upright channel having an inlet port at one end and fluidly connected at the opposite end to said upper end of said main conduit to permit supplementary nutrition to be inserted into said inlet port of said primary conduit to travel through said main conduit and out of said slanted outlet port and into the stomach of the person; g) a secondary conduit consisting of a hollow cylindrical branch channel having an inlet port at one end and fluidly connected at the opposite end to the upper end of said main conduit to permit the insertion of medication into the inlet port of said secondary conduit to travel through said main conduit and out of said slanted outlet port and into the stomach of the person; and h) stop member means integrally formed in the outer surface of said main conduit directly below the juncture of said valve stem, said primary conduit, and said secondary conduit to provide a fixed finger grip on said gastrostomy tube.
Claim 3
Dependent Claim 42 words
An improved gastrostomy tube as recited in claim 1, wherein said main conduit, said primary conduit, said secondary conduit, said valve stem and said finger grip stop member are all integral to each other and fabricated out of a durable plastic material.
Claim 4
Dependent Claim 20 words
An improved gastrostomy tube as recited in claim 2, wherein said balloon is fabricated out of a stretchable rubber material.
