Abstract

A tracheal tube positioning apparatus is located relative to a patient's trachea by engaging the patient's Adam's apple. Indicia on relatively movable sections of the positioning apparatus provides an indication of the distance between the patient's mouth and the patient's larynx. A flexible guide rod is moved through a distance corresponding to the distance between the patient's mouth and larynx, as determined by the positioning apparatus. A magnet is utilized to attract a leading end portion of the guide rod. A plurality of emitters may be disposed in an array around the patient's Adam's apple. Outputs from the emitters are detected by a detector connected with the guide rod and by a detector connected with the tracheal tube. Alternatively, a plurality of detectors may be disposed in an array around the patient's Adam's apple to detect the output from an emitter connected with the guide rod and by an emitter connected with the tracheal tube. Expandable elements may be connected with the guide rod and/or tracheal tube to steer movement along an insertion path.

Claims

exact text as granted — not AI-modified
1 . A method for administering a medication to a treatment site in a body of a patient, the method comprising:
 inserting the medication into the body of the patient;   applying a magnetic field to the body of the patient; and   guiding the medication within the body of the patient to the treatment site with the magnetic field.   
     
     
         2 . The method of  claim 1  wherein guiding the medication within the body of the patient includes controlling the magnetic field. 
     
     
         3 . The method of  claim 2  wherein the magnetic field is controlled by adjusting the strength of the magnetic field. 
     
     
         4 . The method of  claim 1  wherein the magnetic field emanates from a location outside of the patient's body. 
     
     
         5 . The method of  claim 4  wherein the magnetic field is provided by a magnet positioned on an exterior surface of the body of the patient. 
     
     
         6 . The method of  claim 1  wherein the magnetic field emanates from a location within the patient's body. 
     
     
         7 . The method of  claim 6  wherein a magnet generates the magnetic field and the magnet is inserted into the body of the patient through a tubular structure. 
     
     
         8 . The method of  claim 1  wherein the magnetic field is provided by a permanent magnet or an electromagnet. 
     
     
         9 . The method of  claim 1  wherein the magnetic field is provided by an electromagnet and the electromagnet is selectively energized or de-energized. 
     
     
         10 . The method of  claim 1  wherein the magnetic field is provided by an electromagnet and current flow to the electromagnet is reversed in direction to sequentially attract and repel the medication. 
     
     
         11 . The method of  claim 1  wherein interaction between magnetizable or magnetic particles and the magnetic field guide the medication within the body of the patient. 
     
     
         12 . The method of  claim 1  wherein the medication is inserted into the body of the patient at a location remote from the treatment site. 
     
     
         13 . The method of  claim 12  wherein the medication is inserted into the body of the patient through a tubular structure. 
     
     
         14 . The method of  claim 1  wherein the magnetic field is generated with multiple magnets. 
     
     
         15 . A method for controllably guiding a medication from an initial location within a body of a patient to a desired location within the body of the patient, the method comprising:
 applying a magnetic field to the body of the patient; and   moving the medication within the body of the patient from the initial location to the treatment site with the magnetic field.   
     
     
         16 . The method of  claim 15  wherein the magnetic field emanates from a location outside of the patient's body. 
     
     
         17 . The method of  claim 15  wherein the magnetic field emanates from a location within the patient's body. 
     
     
         18 . The method of  claim 17  wherein a magnet generates the magnetic field and the magnet is inserted into the body of the patient through a tubular structure. 
     
     
         19 . The method of  claim 15  wherein the magnetic field is provided by an electromagnet and the electromagnet is selectively energized or de-energized. 
     
     
         20 . The method of  claim 15  wherein the magnetic field is provided by an electromagnet and current flow to the electromagnet is reversed in direction to sequentially attract and repel the medication. 
     
     
         21 . The method of  claim 15  wherein interaction between magnetizable or magnetic particles and the magnetic field guide the medication within the body of the patient. 
     
     
         22 . The method of  claim 15  wherein the medication is inserted into the body of the patient through a tubular structure. 
     
     
         23 . The method of  claim 15  wherein the magnetic field is generated with multiple magnets.
