Abstract
A tubing assembly for use with electronic catheter guidance systems is provided and includes a catheter, an ultrasound transducer disposed within the catheter, and an optional additional external ultrasound transducer. The catheter extends in a longitudinal direction and has a proximal end and a distal end defining a lumen therebetween. Further, the catheter is configured for placement within a patient's digestive tract or respiratory tract. The ultrasound transducer can be located within the catheter's lumen, and the optional external ultrasound transducer can be located on or outside the patient's body. Both ultrasound transducers can transmit ultrasound signals as directed by a processor and can communicate with the processor to deliver ultrasound data to a display device. The attenuation of the ultrasound energy at a selected frequency can indicate placement of the catheter in the digestive tract or respiratory tract. A catheter guidance system and method of use are also provided.
