DEVICE WITH EXTERNAL PRESSURE SENSORS FOR ENHANCING PATIENT CARE AND METHODS OF USING SAME
First Claim
1. A system for monitoring physiologic conditions of a patient, comprising:
- a medical device having an outer surface; and
a pressure sensor disposed about at least a portion of the outer surface of the medical device;
wherein the pressure sensor is capable of detecting a change in pressure when a force is exerted against the outer surface of the medical device.

Abstract
A method for monitoring physiologic conditions of a patient includes inserting an esophageal or other suitable tube into the patient, the tube comprising a lumen having a proximal end, a distal end, and central portion, and a pressure sensor disposed about at least a portion of an outer surface of the lumen of the tube. The pressure sensor is capable of detecting a change in pressure when a force is exerted against the outer surface of the lumen. The tube is then positioned within the patient and an initial pressure reading of the pressure exerted against the pressure sensors disposed about the at least a portion of the outer surface of the lumen of the tube is taken. The method also includes monitoring changes in the initial pressure reading and, if needed, taking a second pressure reading.

15. A method for monitoring physiologic conditions of a patient, comprising:
-
inserting an endotracheal tube through a mouth of the patient, the endotracheal tube comprising a lumen having a proximal end, a distal end, and central portion and an inflatable cuff disposed around the lumen, between the central portion of the lumen and the distal end of the lumen, and a pressure sensor disposed about at least a portion of an outer surface of the lumen of the endotracheal tube;
wherein the pressure sensor is capable of detecting a change in pressure when a force is exerted against the outer surface of the lumen;positioning the endotracheal tube within the patient'"'"'s trachea so that the patient may breath through the endotracheal tube; taking an initial pressure reading of the pressure exerted against the pressure sensors disposed about the at least a portion of the outer surface of the lumen of the endotracheal tube; and monitoring changes from the initial pressure reading. - View Dependent Claims (16, 17, 18)

19. A method for monitoring physiologic conditions of a patient, comprising:
-
inserting an esophageal feeding tube through the nose or mouth of the patient, the esophageal feeding tube comprising a lumen having a proximal end, a distal end, and central portion, and a pressure sensor disposed about at least a portion of an outer surface of the lumen of the esophageal feeding tube;
wherein the pressure sensor is capable of detecting a change in pressure when a force is exerted against the outer surface of the lumen;positioning the esophageal feeding tube within the patient'"'"'s esophagus; taking an initial pressure reading of the pressure exerted against the pressure sensors disposed about the at least a portion of the outer surface of the lumen of the esophageal feeding tube; and monitoring changes from the initial pressure reading. - View Dependent Claims (20)
