An in vivo tube introduction determination device (100) includes a gas detection unit (10) that is connected to a second end (302) of a tube (300) of which a first end (301) is inserted into the living body (200) and a notification unit (20) that provides notification of information based on the output of the gas detection unit (10). The gas detection unit (10) is configured to detect a concentration of a first gas component that is carbon dioxide or oxygen and a concentration of a second gas component having a concentration difference between the stomach and the esophagus.

A system for aiding placement of a nasogastric tube or a nasoduodenal tube and a method for using the same is disclosed, and the system comprises that of: a placing tube; a three-way connector, having a first port, a second port, and a third port, the first port being on the opposite end to the second port, the first port being adjacent to the third port, the first port being connected with a proximal end of the placing tube, the third port being adapted for pumping air or fluid into the three-way connector; an endoscope, having an insertion tube and an image-capturing device, the distal end of the insertion tube being a bending section, the image-capturing device being located in the front end of the bending section; and a display unit, connected with the endoscope.

A system for feeding and evacuation has a feeding tube in place into a subject's stomach cavity, having a Luer-Lock compatible female connector on an outboard end, a feed source, a unique Lopez valve having a conventional connector on one end and a male Luer-Lock connector on the other end in place of the conventional tapered connector, a suction tube coupled to a suction source, the suction tube having a connector compatible with the conventional connector of the conventional Lopez valve on an end away from the suction source. With the feeding tube connected to the feed source, nutrients are supplied to the subject through the feeding tube, and with the feed source disconnected, the body of the unique Lopez valve connected to the feed tube by the male Luer-Lock extension and to the suction tube, the subject's stomach cavity is exposed to suction controlled by the conventional Lopez valve.

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.

A device and method for verifying the proper position of catheters in the body by means of acoustic reflectometry, the device including a sound source, one or more sound receivers, a tube with compliant walls and open distal end to be introduced through an entrance to a body cavity, the sound source and receiver(s) coupled to the proximal end of the tube, a processor for causing the sound source to generate an acoustic excitation signal, the processor processing the acoustic signals sensed by the sound receiver(s) and generating an approximation of the acoustic impulse response of the tube, and the processor analyzing the acoustic impulse response to determine the position of the tube in the body cavity.

A gastrointestinal catheter for insertion into a treatment site in a patient, the treatment site including at least one of a first treatment site and a second treatment site, where the catheter includes at least one of a first and a second treatment member; the proximal portions of the first and second treatment members may be detachably or slidably conjoinable side by side; the distal portions of the first and second treatment members are separate from each other. The distal end of the first treatment member is configured for insertion into the first treatment site; the second treatment member is configured to be placed at a second treatment site. The distal end region of the first treatment member has an anchoring configuration adapted to anchor the distal end region within the first treatment site, the distal end region is further capable of elastically assuming a linear constrained configuration.

The present invention provides a catheter for assisting recovery from dysphagia.

An enteral feeding tube includes a tube body particularly adapted or configured to resist kinking and clogging. That tube body is characterized by a particular equation.

A system is described herein. The system includes a smart nasogastric tube and a computing device. A distal end of the smart nasogastric tube is received by an internal area of a patient and includes a tip, a non-heating light source, and a camera. The tip includes a plurality of side holes or slots used for suctioning and an offset diagonal funneled slot proximate the camera used to pass a sponge brush under direct visualization. The camera is configured to capture a high definition and color video of the internal area of the patient and transmit the video to an application of a computing device. The smart nasogastric tube also includes a central tube for suctioning, feeding or lavage with a proximal port. The application of the computing device receives the video from the camera such that a healthcare professional can view the video in real-time. The video may further be transmitted to a third-party via a Health Insurance Portability and Accountability Act (HIPPA) compliant message or live video stream. The smart nasogastric tube may be presented to patients in many points of implementation, such as emergency departments, urgent care centers, a family practitioners officer, or a medical ward.

A temporary tube placement system includes a tube having a proximal end and a distal end, a camera supported by the tube at the distal end, a plurality of fiber optic filaments through which light from a light source travels from the proximal end to the distal end, a screen for displaying images from the camera, and a power source electrically attached to the camera and the light source. The enteral tube includes a tube having a distal end portion for placement within a patient and a proximal end portion and a lumen increasing in cross section from the proximal end portion toward the distal end portion along at least a portion of the tube.
