Abstract

A method and apparatus for administering a test to detect the esophagitis in a patient utilizes a sealed pliable tube. When the tube is unsealed and inserted in the esophagus of a patient, an acidic solution stored in the tube flows into the esophagus and, if the patient has esophagitis, causes the chest pain or other symptoms which the patient experiences during esophagitis.

Claims

1. A method of administering a test to a patient to detect the condition of esophagitis in the patient, including the steps of:

(a) providing a tube having

(i) at least one pliable wall,

(ii) first and second sealed ends,

(iii) a reservoir circumscribed by said wall and extending from said first to said second end, and

(iv) an acidic aqueous solution stored in said reservoir,

said tube being shaped and dimensioned such that

said first end can be inserted through an anatomical opening in the face of a patient and into the end of the esophagus adjacent the stomach,

after said first end is unsealed and inserted in the esophagus and said second end is unsealed, the peristaltic action of the esophagus generates forces which act to draw fluid through said unsealed first end, and

after said first end is inserted into the end of the esophagus adjacent the stomach, said second end extends outwardly from the patient'"'"'s face and can be grasped;

said first end being shaped and dimensioned such that

when said first end is unsealed and inserted in the esophagus and said second end is unsealed, said solution flows from said reservoir out through said unsealed first end under atmospheric pressure and the force of gravity, and

when said first end is unsealed and inserted in the esophagus and said second end remains sealed, said solution remains in said tube and does not flow from said reservoir out through unsealed first end;

(b) unsealing said first end and inserting said first end of said tube through an anatomical opening in the patient'"'"'s face and into the lower end of the patient'"'"'s esophagus adjacent the stomach;

(c) unsealing said second end to permit atmospheric pressure, the force of gravity and peristaltic action to cause said solution to flow through said unsealed first end into the lower end of the patient'"'"'s esophagus adjacent the stomach; and

,

(d) monitoring the patient to determine if the patient experiences chest pain or other symptoms associated with esophagitis.

2. The method of claim 1 wherein

(a) the anatomical opening comprises the mouth of the patient;

(b) said tube is shaped and dimensioned such that in said first end is inserted through the mouth and into the end of the esophagus adjacent the stomach; and

,

(c) after said first end is inserted through the mouth into the end of the esophagus adjacent the stomach in step (b), said second end extends outwardly from the mouth and can be grasped.

3. The method of claim 1 wherein

(a) the anatomical opening comprises the nose of the patient;

(b) said tube is shaped and dimensioned such that in step (b) said first end is inserted through the nose and into the end of the esophagus adjacent the stomach; and

,

(c) said second end extends out of the nose after said first end is inserted into the end of the esophagus adjacent the stomach in step (b).

4. A method of administering a test to a patient to detect the condition of esophagitis in the patient, including the steps of

(a) providing a tube including

(i) at least one wall,

(ii) a first sealed end for insertion through an anatomical opening in the patient'"'"'s face into the end of the esophagus adjacent the stomach,

(iii) a reservoir circumscribed by said wall,

(iv) a second sealed end, said tube being shaped and dimensioned such that said second end extends outwardly from the patient'"'"'s face after said first end is inserted through an anatomical opening in the patient'"'"'s face into the end of the esophagus adjacent the stomach, said reservoir extending from said first to said second end,

(v) a liquid solution stored in said reservoir while said first end of said tube is inserted into the esophagus, said solution effective to irritate the burned lining of the esophagus when the patient has esophagitis,

said tube being shaped and dimensioned such that

when said first end is unsealed and inserted in the esophagus and said second end is unsealed, the force of gravity and atmospheric pressure cause said liquid solution to flow from said reservoir out through said unsealed first end, and

when said first end is unsealed and inserted in the esophagus and said second end remains sealed, said liquid solution remains in said reservoir and does not flow from said reservoir out through said unsealed first end;

(b) unsealing and inserting said first end of said tube through an anatomical opening in the patient'"'"'s face and into the end of the esophagus adjacent the stomach;

(c) unsealing said second end to permit atmospheric pressure, and the force of gravity to cause said solution to flow through said unsealed first end of said tube and into the end of the patient'"'"'s esophagus adjacent the stomach; and

,

(d) monitoring the patient to determine if the patient experiences chest pain or other symptoms associated with esophagitis.

5. The method of claim 4 wherein said reservoir is shaped and dimensioned such that in step (c), said liquid solution completely empties from said reservoir through said unsealed first end under the force of gravity and atmospheric pressure in a period of time in the range of from five seconds to five minutes.

6. The method of claim 5 wherein the volume of said liquid solution stored in said reservoir in step (a) is in the range of one-half milliliter to twenty-five milliliters.

7. The method of claim 4 wherein the volume of said liquid solution stored in said reservoir in step (a) is in the range of one-half milliliter to twenty-five milliliters.
