Abstract

A method in which a tube assembly is configured to be used in conjunction with an electromagnetic tube assembly guidance system. The tube assembly includes a first connector, a feeding tube connected to the first connector, a second connector connected to the feeding tube, and a suctioning tube connected to the second connector. The suctioning tube is configured to receive the feeding tube. The feeding tube is configured to allow enteral feeding while the suctioning tube is configured to allow suctioning or decompression of a patient'"'"'s stomach.

Claims

1. A method of guiding a feeding tube to a desired location within a patient'"'"'s body, wherein a suctioning tube is configured to receive the feeding tube, wherein the feeding tube includes a first end and a second end defining a first length and the suctioning tube includes a first end and a second end defining a second length, wherein the second end of the feeding tube and the second end of the suctioning tube are configured to be inserted into the patient'"'"'s body, the method comprising:

(a) placing a electromagnetic field generator coupled to a wire assembly at the second end of the feeding tube;

(b) placing a non-invasive transceiver on the patient'"'"'s body, wherein the non-invasive transceiver is configured to detect an electromagnetic field generated by the electromagnetic field generator;

(c) inserting the feeding tube and suctioning tube into the patient'"'"'s body via a single nare;

(d) tracking a position of the electromagnetic field generator via a display device, wherein a processor executes instructions to the display device to display the location of the electromagnetic field generator as detected by the non-invasive transceiver; and

(e) advancing the second end of the feeding tube to the desired location within the patient'"'"'s body using the position of the electromagnetic field generator displayed on the display device for guidance, wherein the desired location is the patient'"'"'s stomach or the patient'"'"'s jejunum, wherein the first length is greater than the second length by at least a distance from the patient'"'"'s stomach to the patient'"'"'s jejunum, wherein the first end of the feeding tube is connected to a first y-port connector and the first end of the suctioning tube is connected to a second y-port connector, wherein the second y-port connector is positioned between the first y-port connector and the second end of the suctioning tube.

2. The method of claim 1, wherein the second end of the suctioning tube is advanced only as far as the patient'"'"'s stomach, wherein the second end of the feeding tube is advanced to the patient'"'"'s stomach, wherein the second end of the feeding tube remains inside the patient'"'"'s stomach for enteral feeding into the patient'"'"'s stomach.

3. The method of claim 2, wherein the second end of the feeding tube and the second end of the suctioning tube are simultaneously advanced into the patient'"'"'s stomach.

4. The method of claim 1, wherein the second end of the suctioning tube is advanced only as far as the patient'"'"'s stomach, wherein the second end of the feeding tube is advanced into the patient'"'"'s jejunum for enteral feeding into the patient'"'"'s jejunum.

5. The method of claim 1, further comprising a step of removing the electromagnetic field generator and the wire assembly from the patient'"'"'s body after the desired location is reached.

6. The method of claim 1, wherein a tubular insulator covers a portion of the wire assembly.

7. The method of claim 1, wherein a sleeve secures the first end of the suctioning tube to the second y-port connector.

8. The method of claim 1, wherein the first y-port connector includes a medicine delivery branch.

9. The method of claim 1, wherein the second y-port connector includes a suctioning branch.

10. The method of claim 1, wherein the non-invasive transceiver is placed on the patient'"'"'s chest.
