Abstract

A guide for an esophageal echo probe includes a bite block with a collar about one end thereof to seat about the patient'"'"'s mouth and a sleeve of low friction, flexible, form-retaining material having a generally arcuate configuration and dimensioned and configured to extend from the patient'"'"'s mouth through the ovopharynx and into the esophagus. A secondary guide extends along the length of the bite block and sleeve and provides a passage seating an orogastric tube to lead the sleeve through the ovopharynx and into the esophagus. The passage through the bite block and sleeve is dimensioned to slidably receive and guide a transesophageal echo probe for placement in the patient'"'"'s body.

Claims

1. A guide for an esophageal probe comprising:

(a) a bite block of relatively bite resistant material and providing a passage therethrough, said bite block having a first end and a second end, said first end having a collar including means for seating about a patient'"'"'s mouth, said bite block further having a body dimensioned and configured to seat within a patient'"'"'s mouth;

(b) a hollow sleeve of low friction, relatively flexible, form-retaining material extending from said second end of said bite block, said hollow sleeve having a generally arcuate configuration and being dimensioned and configured to extend from a patient'"'"'s mouth through the oropharynx and into the esophagus, and having an interior portion in communication with said passage of said bite block; and

(c) secondary guide means for slidably seating an orogastric tube extending the length of said bite block and said hollow sleeve for guiding along an orogastric tube through the oropharynx into the esophagus, said passage of said bite block and said hollow sleeve being dimensioned to slidably receive therethrough and guide a transesophageal probe for placement in a patient'"'"'s body.

2. The esophageal probe guide in accordance with claim 1 wherein said bite block is fabricated from synthetic resin and is relatively rigid.

3. The esophageal probe guide in accordance with claim 1 wherein said sleeve is fabricated from synthetic resin.

4. The esophageal probe guide in accordance with claim 1 wherein said sleeve extends about said body of said bite block.

5. The esophageal guide in accordance with claim 4 wherein there is included a resiliently deformable synthetic resin layer between said sleeve and body.

6. The esophageal probe guide in accordance with claim 1 wherein said sleeve tapers to a reduced cross section at its end spaced from said bite block.

7. The esophageal probe guide in accordance with claim 1 wherein said secondary guide means is provided along the outer surface of said body of said bite block and of said sleeve.

8. The esophageal probe guide in accordance with claim 7 wherein said collar of said bite block has a passage therethrough communicating with said passage of said secondary guide means.

9. The esophageal probe guide in accordance with claim 7 wherein said secondary guide means is provided by a flexible synthetic resin strip having end and side margins, said side margins being bonded to said sleeve.

10. A guide for an esophageal probe comprising:

(a) a bite block of relatively bite resistant material and providing a passage therethrough, said bite block having a first end and a second end, said first end having a collar including means for seating about a patient'"'"'s mouth, said bite block further having a body dimensioned and configured to seat within a patient'"'"'s mouth;

(b) a hollow sleeve of low friction, relatively flexible, form-retaining material extending from said second end of said bite block, said hollow sleeve having a generally arcuate configuration and being dimensioned and configured to extend from a patient'"'"'s mouth through the oropharynx and into the esophagus, and having an interior portion in communication with said passage of said bite block, and said sleeve being fabricated from a synthetic resin and extending about said body of said bite block; and

(c) secondary guide means for slidably seating an orogastric tube extending the length of said bite block and sleeve, said guide means being provided along the outer surface of said body of said bite block and sleeve and providing a passage dimensioned to slidably seat an orogastric tube to lead said sleeve through the oropharynx into the esophagus, said passage of said bite block and said hollow sleeve being dimensioned to slidably receive therethrough and guide a transesophageal probe for placement in a patient'"'"'s body.

11. The esophageal probe guide in accordance with claim 10 wherein said bite block is fabricated from a relatively rigid synthetic resin and said sleeve tapers to a reduced cross section at its end spaced from said bite block.

12. The esophageal probe guide in accordance with claim 10 wherein there is included a layer of resiliently deformable material between said sleeve and body.

13. The esophageal probe guide in accordance with claim 10 wherein said collar of said bite block has a passage therethrough communicating with said passage of said secondary guide means and said secondary guide means is provided by a flexible synthetic resin strip having end and side margins, said side margins being bonded to said sleeve.

14. In a method for inserting a transesophageal probe into a patient, the steps comprising:

(a) providing a guide comprising;

(i) a bite block of relatively bite resistant material and providing a passage therethrough, said bite block having a first end and a second end, said first end having a collar including means for seating about a patient'"'"'s mouth, said bite block further having a body dimensioned and configured to seat within a patient'"'"'s mouth;

(ii) a hollow sleeve of low friction, relatively flexible, form-retaining material extending from said second end of said bite block, said hollow sleeve having a generally arcuate configuration and being dimensioned and configured to extend from a patient'"'"'s mouth through the oropharynx and into the esophagus, and having an interior portion in communication with said passage of side bite block; and

(iii) secondary guide means for slidably seating an orogastric tube extending the length of said bite block and hollow sleeve for guiding along an orogastric tube through the ovopharynx into the esophagus, said passage in said bite block and said hollow sleeve being dimensioned to slidably receive and guide a transesophageal probe for placement in a patient'"'"'s body;

(b) inserting into the mouth of a patient an orogastric tube and said guide, said tube extending along said secondary guide means;

(c) manipulating said guide to cause said sleeve to slide along said orogastric tube and pass through the patient'"'"'s oropharynx and into the esophagus and said bite block to seat in the patient'"'"'s mouth; and

(d) sliding an esophageal echo probe through said passage of said bite block and said tube into the patient'"'"'s body.

15. The method in accordance with claim 14 wherein said step of providing a guide further comprises the step of providing a guide in which said bite block is fabricated from a relatively rigid synthetic resin, said sleeve is fabricated from a synthetic resin, said sleeve is fabricated from a synthetic resin, and said sleeve extends about said body of said bite block.

16. The method in accordance with claim 14 wherein said step of providing a guide further comprises the step of providing a guide in which there is included a layer of resiliently deformable plastic material between said sleeve and body, and wherein said sleeve tapers to a reduced cross section at its end spaced from said bite block.

17. The method in accordance with claim 14 wherein said step of providing a guide further comprises the step of providing a guide in which said secondary guide means is provided along the outer surface of said body of said bite block and sleeve.

18. The method in accordance with claim 17 wherein said step of providing a guide further comprises the step of providing a guide in which said collar of said bite block has a passage therethrough communicating with said passage of said secondary guide means, and wherein said secondary guide means is provided by a flexible synthetic resin strip having its side margins bonded to said sleeve.
