Medical Device Placement and Monitoring System Utilizing Radio Frequency Identification
First Claim
1. A placement and monitoring system for use by a clinician during insertion of a medical device within a patient, comprising:
- a radio frequency identification tag secured to said medical device, said radio frequency identification tag comprising at least one feedback initiator configured to provide information concerning the location of said radio frequency identification tag within said patient;
at least one feedback receiver configured to receive said information from said at least one feedback initiator; and
at least one notifying device configured to present said information concerning the location of said radio frequency identification tag to said clinician;
wherein said information concerning the location of said radio frequency identification tag within said patient is communicated from said at least one feedback initiator to said at least one feedback receiver via transmission of a radio frequency signal.

Abstract
A medical device placement and monitoring system is provided that includes numerous circuits that can be used alone or in combination. The circuits include a feedback initiator, a feedback receiver, and a clinician notifying device. By various means in the provided circuits, the feedback initiator provides information about the location of a radio frequency identification tag secured to a medical device inserted within a patient. This information or data is received and analyzed by the feedback receiver that monitors the circuit, which then transmits an output to the clinician notifying device to alert or advise the attending clinician of this information. The data that is output supplies information about the location of the radio frequency identification tag to the clinician, thereby assisting the clinician in placement of a variety of medical devices including nasogastric or endotracheal tubes, as well as in monitoring proper device placement after initial insertion.

14. A placement and monitoring system for use by a clinician during insertion of a medical device within a patient, comprising:
-
a radio frequency identification tag secured to said medical device, said radio frequency identification tag comprising a pH sensor electrically connected to a radio frequency transmitter, wherein said pH sensor detects the pH of a fluid immediately adjacent said radio frequency identification tag and outputs a detected pH signal to said radio frequency transmitter; a pH monitor for receiving said detected pH signal from said radio frequency transmitter; and a pH display in electrical communication with said pH monitor, said pH display receives said detected pH signal and displays said detected pH signal to said clinician. - View Dependent Claims (15, 16, 17, 18)

19. A placement and monitoring system for use by a clinician during insertion of a medical device within a patient, comprising:
-
a radio frequency identification tag secured to said medical device, said radio frequency identification tag comprising; a pH sensor for detecting the pH of a fluid adjacent said pH sensor, wherein said pH sensor outputs a detected pH signal; a radio frequency transmitter in electrical communication with said pH sensor, wherein said radio frequency transmitter receives said detected pH signal from said pH sensor; an antenna in electrical communication with said radio frequency transmitter, wherein said antenna transmits said detected pH signal; and a capsule enclosing said radio frequency identification tag and providing for biocompatibility of said radio frequency identification tag with said patient; and a control panel comprising an enclosure for electronics disposed external to said patient, said control panel further comprising; a pH monitor for receiving said detected pH signal transmitted from said antenna; and a pH display in electrical communication with said pH monitor, wherein said pH display receives said detected pH signal and displays said detected pH signal to said clinician; wherein said radio frequency identification tag is disposed on the distal end of said medical device and said medical device is selected from the group consisting of a nasogastric tube, an endotracheal tube, and a catheter. - View Dependent Claims (20)
