Esophageal catheter with gauge
First Claim
1. A gauging esophageal catheter insertable into an esophagus of an associated subject, the subject having a determinable height, the esophageal catheter comprising:
- an elongated, flexible body portion having a proximal end and a distal end, said flexible body portion being insertable at least partially orally or nasally, said distal end being insertable into the esophagus of the subject;
an instrument carried on said distal end; and
said body portion having a series of user visible gradations for permitting selective positioning of said distal end at a predetermined insertion depth within the subject, said gradations being calibrated according to subject height and said gradations labeled in measurements corresponding to subject height in accordance with oral or nasal insertion.

Abstract
A gauging esophageal catheter or stethoscope which is insertable into the esophagus or stomach of a subject or patient, has an elongated, flexible body portion having an instrument carried on a distal end. The catheter has a series of user visible gradations for permitting selective positioning of the instrument at a predetermined insertion depth within the subject. The gradations are calibrated to the height, weight or body surface area of the subject. The gradations may be printed on the body portion, or the body portion may have a transparent portion, and the gradations may be carried on a member internal thereto which is visible through the transparent portion.

11. A gauging catheter insertable into an esophagus of an associated patient wherein the patient has a predetermined height, the catheter comprising:
-
an elongated, tubular, flexible body portion for insertion into one of a patient'"'"'s mouth or nose, and having a proximal and a distal end, said distal end being insertable, at least, into the esophagus of the patient; and a plurality of user-visible patient height indicators carried on the proximal end of the body portion for permitting selective positioning of the distal end at a predetermined insertion depth within the patient wherein the visible indicators are calibrated according to a range of heights and marked in measuring units corresponding to patient heights. - View Dependent Claims (12, 13)
