Abstract
Abstract Apparatus for automatic inflation of cavities of the body, for instance the stomach, in which an inflating tube insertable with one end portion into the stomach is connected by a tube to a tank containing a gas under pressure and wherein sensing means cooperate with the tube for sensing the gas pressure in the stomach and automatically shut off further passage of gas under pressure into the stomach when the gas pressure in the latter has reached a predetermined value. The end of the inflating tube which is inserted into the stomach preferably carries a camera and illuminating means so that the interior of the body, after being inflated, may be photographed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
190 words
Apparatus for automatic inflation of cavities of a body, such as a stomach of a patient, to a predetermined degree, comprising, in combination, a source of gas under pressure; an inflating tube insertable with an open end thereof into the cavity; tube means connecting said source of gas under pressure to the other end of said inflating tube; manually operable valve means connected to said tube means movable between a closed and an open position for permitting in said open position flow of gas under pressure through said tube means, said inflating tube and said open end thereof into said cavity to inflate the latter; sensing means cooperating with said tube means for sensing the gas pressure in the cavity transmitted to said tube means through said inflating tube; and automatic shut-off means connected to said sensing means for automatically shutting off further passage of gas under pressure into said cavity when the gas pressure in the latter has reached a predetermined value, and for instantaneously restoring flow of gas into said cavity when the gas pressure in the latter after inflation of said cavity drops below said predetermined value.
Claim 2
Dependent Claim
190 words
Apparatus for automatic inflation of cavities of a body, such as a stomach of a patient, to a predetermined degree, comprising, in combination, a source of gas under pressure; an inflating tube insertable with an open end thereof into the cavity; tube means connecting said source of gas under pressure to the other end of said inflating tube; manually operable valve means connected to said tube means movable between a closed and an open position for permitting in said open position flow of gas under pressure through said tube means, said inflating tube and said open end thereof into said cavity to inflate the latter; sensing means cooperating with said tube means for sensing the gas pressure in the cavity transmitted to said tube means through said inflating tube; and automatic shut-off means connected to said sensing means for automatically shutting off further passage of gas under pressure into said cavity when the gas pressure in the latter has reached a predetermined value, and for instantaneously restoring flow of gas into said cavity when the gas pressure in the latter after inflation of said cavity drops below said predetermined value.
Claim 3
Dependent Claim
50 words
An apparatus as defined in claim 1, whereIn said automatic shut-off means comprises a normally open solenoid valve, and wherein said sensing means comprises switch means for energizing said solenoid valve to move the latter to the closed position thereof when the pressure in said cavity reaches a predetermined value.
Claim 4
Dependent Claim
42 words
An apparatus as defined in claim 1, and including a throttle valve in said tube means between said source of gas under pressure and said shut-off means for reducing the pressure of said source to a pressure suitable for inflating the cavity.
Claim 5
Dependent Claim
26 words
An apparatus as defined in claim 3, and including gauge means communicating with said tube means downstream of said throttle valve for indicating said reduced pressure.
Claim 6
Dependent Claim
59 words
An apparatus as defined in claim 4, wherein said gauge means communicates with said tube means between said throttle valve and said shut-off means, and including additional gauge means communicating with said tube means between said pressure sensing means and said manually operable valve means for indicating the pressure in said cavity after said valve means has been opened.
Claim 7
Dependent Claim
49 words
An apparatus as defined in claim 1, and including photographic camera means at said one end of said inflating tube for photographing the interior of said cavity after the latter has been inflated, and actuating means at the other end of said inflating tube for actuating said camera means.
Claim 8
Dependent Claim
34 words
An apparatus as defined in claim 6, wherein said manually operable valve means and said actuating means at said other end of said inflating tube are connected to each other to form a unit.
Claim 9
Dependent Claim
88 words
An apparatus as defined in claim 5, wherein said source of gas under pressure is a tank containing a gas under pressure and including a carrying case housing said tank, said tube means, said throttle valve, said sensing means, said shut-off means and said gauge means connected thereto and cooperating therewith, said gauge means being mounted in one wall of said carrying case so as to be visible from the outside thereof, and said throttle valve having an operating portion projecting from the exterior of said carrying case.
Claim 10
Dependent Claim
68 words
An apparatus as defined in claim 8, and including a connecting nipple connected to the downstream end of said tube means and projecting through one wall of said carrying case to the exterior of the latter, and an additional manually operable valve connected to said tube means between said nipple and said additional gauge means and having an operating portion operable from the exterior of said carrying case.
Claim 11
Dependent Claim
63 words
An apparatus as defined in claim 9 and including photographic camera means at said one end of said inflating tube for photographing the interior of the cavity after the latter has been inflated, said camera means including actuating means at the other end of said inflating tube and forming with said first-mentioned manually operable valve means a unit releasably connectable to said nipple.
