There is provided system for monitoring spontaneous breathing of a mechanically ventilated target individual, comprising: a feeding tube for insertion into a distal end of an esophagus of the individual, sensor(s) disposed on the feeding tube at a location such that the sensor(s) is located at the distal end of the esophagus of the individual when the feeding tube is in use, wherein the sensor(s) is positioned for sensing values by contact with the tissue of the esophagus including a lower esophageal sphincter (LES) and/or tissue in proximity to the LES, and code for computing an indication of a frequency band of diaphragm movement of the individual according to an analysis of values sensed by the sensor(s), and for adjustment of parameter(s) of a mechanical ventilator for mechanically ventilating the individual, wherein the instructions for adjustment are computed while the feeding tube is in use.

Disclosed is an active inserted gastric tube with an intra-body communication function, including a tube body, a pulse module, an intra-body communication module and a control module. The pulse module is arranged at a front end of the tube body, and is configured to generate a pulse signal. the intra-body communication module is configured to receive the pulse signal generated by the pulse module and transmit the pulse signal to the control module. The control module is configured to analyze the received pulse signal. In this way, the pulse signal is generated by the pulse module, and the gastric tube is inserted into the esophagus through the tube body. The pulse signal is transmitted through a human body to realize an intra-body communication. The control module analyzes the pulse signal transmitted through the human body, so as to identify whether the tube body is inserted into the esophagus or trachea.

There is provided feeding tubes including an electromagnetic sensor including a sensor body comprising a core positioned at a distal end of the sensor lumen, and a wire extending along the length of the feeding tube, wherein an RF induced heating of the feeding tube in an MRI environment is below 5 degrees.

There is provided system for monitoring spontaneous breathing of a mechanically ventilated target individual, including: a feeding tube for insertion into a distal end of an esophagus of the individual, sensor(s) disposed on the feeding tube at a location such that the sensor(s) is located at the distal end of the esophagus of the individual when the feeding tube is in use, wherein the sensor(s) is positioned for sensing values by contact with the tissue of the esophagus including a lower esophageal sphincter (LES) and/or tissue in proximity to the LES, and code for computing an indication of a frequency band of diaphragm movement of the individual according to an analysis of values sensed by the sensor(s), and for adjustment of parameter(s) of a mechanical ventilator for mechanically ventilating the individual, wherein the instructions for adjustment are computed while the feeding tube is in use.

One or more techniques and/or systems are disclosed for a gastrojejunostomy tube (G-J tube) with a replaceable balloon portion. An example G-J tube can comprise a connection point that is appropriately disposed distally from the balloon portion. The connection can be used to detach a proximal portion from a distal portion of the G-J tube; and a replacement proximal portion can be attached, and the G-J tube can be moved to the desired location. The example G-J tube can comprise a jejunal tube, a gastric tube, and a balloon tube, respectively sized to dispose the distal opening in an appropriate location in the target patient. The proximal portion can comprise at least the balloon tube, the port of the gastric tube, and the port of the jejunal tube.

An enteral feeding device permitting diversion of gastrointestinal fluid from an afferent limb to an efferent limb of gastrointestinal tract in a subject is provided. The device can be used to reduce leakage from around device and thus reduce morbidity associated with such leakage. In certain embodiments the enteral feeding device is a jejunostomy tube (J-tube). Also provided are methods for positioning and using the enteral feeding device. Also provided are kits for positioning and using the enteral feeding device.

A medical device position notification system including a negative pressure device. The medical device is configured to be inserted into an orifice of the patient. The negative pressure device provides information related to the position of the medical device in the patient's body and communicates the information in real-time. The negative pressure device may also be coupled to a sensor, processor, and display device and indicates the position of the medical device in the patient's body in real-time.

A tubing assembly for use with electronic catheter guidance systems is provided and includes a catheter and an acoustic sensor. The catheter extends in a longitudinal direction and has a proximal end and a distal end that define a lumen therebetween. Further, the catheter is configured for placement within a patient's digestive tract. The acoustic sensor can be located within the lumen of the catheter or in a sampling chamber connected to the catheter. The acoustic sensor can communicate with a processor to deliver sound data to a display device. The appearance of random spikes on a frequency versus time spectrogram can indicate placement of the catheter in the digestive tract, while a rhythmic/repetitive pattern on a frequency versus time spectrogram can indicate placement of the catheter in the respiratory tract. A catheter guidance system and method for accurately placing a catheter in the digestive tract are also provided.

Methods of inserting a tube through the nasopharynx of a patient are disclosed. The methods of inserting a tube through a nasopharynx of a patient includes the steps of inserting the tube through a naris of the patient; and when a distal end of the tube is proximate a rear surface of the nasopharynx, pulling on or holding in place a thread-like member attached to a tube portion of the distal end of the tube so as to alter an initial direction of the distal end of the tube and point the distal end of the tube towards a throat of the patient. Kits for inserting a tube through the nasopharynx of a patient are also disclosed. The kits include a tube sized so as to move through a nasopharynx of a patient; and a thread-like member that is attachable to a tube portion of a distal end of the tube and can be tensioned so as to alter an initial direction of the distal end of the tube and point the distal end of the tube towards a throat of the patient. Methods of making kits for inserting a tube through the nasopharynx of a patient are further disclosed.
