Abstract
Abstract A dual balloon retention and positioning arrangement in an enemata administering device. Both balloons are mounted on the stem. The first balloon, internal of the patient, is air inflated. The second balloon, external of the patient, is in communication with the interior of the stem and is automatically inflated by the applied barium sulphate suspension fluid when the fluid is flowed through the stem to the patient.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
170 words
In an enemata administering device having a hollow stem with an exit port at a first end thereof and an inlet at the second end thereof, the improvement comprising: a first inflatable and deflatable annular retention balloon sealed across a portion of the stem near the forward end thereof, an airway extending to a first post in the stem under said first balloon to provide inflation and deflation of said first balloon, and a second inflatable and deflatable annular balloon sealed across a portion of the stem rearward from said first balloon, said stem having a second port providing communication between the interior of said stem and the interior of said second balloon, said second balloon inflating solely when liquid is flowed through said stem, and said first balloon inflating solely when fluid is forced through said airway, when said balloons are so inflated, said second balloon automatically conforming to a patient's external anatomy and causing the inflated first balloon to be held in a sealing position within the patient.
Claim 2
Dependent Claim
170 words
In an enemata administering device having a hollow stem with an exit port at a first end thereof and an inlet at the second end thereof, the improvement comprising: a first inflatable and deflatable annular retention balloon sealed across a portion of the stem near the forward end thereof, an airway extending to a first post in the stem under said first balloon to provide inflation and deflation of said first balloon, and a second inflatable and deflatable annular balloon sealed across a portion of the stem rearward from said first balloon, said stem having a second port providing communication between the interior of said stem and the interior of said second balloon, said second balloon inflating solely when liquid is flowed through said stem, and said first balloon inflating solely when fluid is forced through said airway, when said balloons are so inflated, said second balloon automatically conforming to a patient's external anatomy and causing the inflated first balloon to be held in a sealing position within the patient.
