Abstract
Abstract Barium enema fluid is supplied to a patient through a three-way union of conduits, one of which is connected to a gravity fed barium supply source, another of which is connected with a source of air under pressure, and the other of which is an evacuation line connected to a source of suction. Each conduit is controlled by an individual valve. The valves are opened and closed in a prescribed sequence as directed by a radiologist who takes X-rays at various stages during and after administration of the enema.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
134 words
Apparatus for administering a barium enema comprising, in combination: a barium supply source ; with an associated delivery conduit; a pressurized air supply source ; with an associated delivery conduit; a source of suction with an associated delivery conduit; and an enema delivery conduit; a multi-way conduit union means; a portable housing enclosing the multi-way union means; the union having a terminal portion individual to each conduit with each said terminal portion extending through and supported by an adjacent wall of the housing; individual conduits connecting said terminal portions of the union with the barium, air, and suction sources, respectively, and with the enema delivery conduit; and a control valve in each of said union terminal portions connected with the barium, air, and suction delivery conduits; the valves being disposed externally of the housing.
Claim 2
Dependent Claim
134 words
Apparatus for administering a barium enema comprising, in combination: a barium supply source ; with an associated delivery conduit; a pressurized air supply source ; with an associated delivery conduit; a source of suction with an associated delivery conduit; and an enema delivery conduit; a multi-way conduit union means; a portable housing enclosing the multi-way union means; the union having a terminal portion individual to each conduit with each said terminal portion extending through and supported by an adjacent wall of the housing; individual conduits connecting said terminal portions of the union with the barium, air, and suction sources, respectively, and with the enema delivery conduit; and a control valve in each of said union terminal portions connected with the barium, air, and suction delivery conduits; the valves being disposed externally of the housing.
Claim 3
Dependent Claim
14 words
In the apparatus of claim 1, said source of suction being a vacuum pump.
Claim 4
Dependent Claim
15 words
In the apparatus of claim 1, said source of suction being a water-faucet venturi fitting.
Claim 5
Dependent Claim
15 words
In the apparatus of claim 1, said air supply source being a hand bulb pump.
Claim 6
Dependent Claim
16 words
In the apparatus of claim 1, said barium supply source being a gravity feed enema bag.
Claim 7
Independent Claim
69 words
A method of administering a barium enema, which comprises the sequential steps of: injecting into an intestinal organ of a patient, by gravity feed, a quantity of barium for coating the interior of the organ; removing by suction barium in excess of the quantity required; injecting into the organ pressurized air to inflate the organ somewhat; discontinuing the injection of air; and thereafter removing residal barium from the organ.
