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.

A tubing assembly for electronic catheter guidance systems is provided and can include a catheter, an internal acoustic transducer and an external acoustic transducer. The catheter extends in a longitudinal direction and has proximal and distal ends that define a lumen therebetween. Further, the catheter is configured for placement within a patient's digestive or respiratory tract. The internal acoustic transducer can be located within the catheter's lumen, and the external acoustic transducer can be located on or outside the patient's body. The transducers can transmit and/or receive acoustic signals as directed by a processor and communicate with the processor to deliver sound data to a display device. The frequency response and/or attenuation of the signals can indicate placement of the catheter in the digestive tract compared to the respiratory tract. A catheter guidance system and method for accurately placing a catheter in the digestive or respiratory tract are also provided.

A non-electrically driven enteral feeding pump including an expandable elastomeric bladder is provided. The enteral feeding pump includes a fluid delivery tube. The fluid delivery tube controls flow rate of fluid from the pump. The present invention further describes an enteral feeding pump assembly including the portable enteral feeding pump and a peristaltic pump. The peristaltic pump can be configured to be operatively coupled to the elastomeric bladder of the enteral feeding pump for transferring fluid from a reservoir external to the elastomeric bladder into a chamber of the elastomeric bladder.
