There is provided a system for managing reflux during an enteral feeding, comprising: (i) a non-transitory memory having stored thereon a code for execution by at least one hardware processor of a computing device, the code comprising: code for receiving electrical signals outputted by at least one reflux event sensor disposed within a digestive system of a patient; code for determining a gastric reflux event based on an analysis of the electrical signals; code for outputting instructions to pause enteral feeding of the patient by a feeding controller that regulates enteral feeding of the patient using an enteral feeding tube positioned within the digestive system of the patient; and (ii) an evacuation controller that directs back-flow of digestive contents from the digestive system of the patient to an external evacuation reservoir through an evacuation tube.

The present invention discloses a stomach tube for preventing aspiration, comprising: a control circuit, an air pump, a PH sensor and a stomach tube provided with an air sack, wherein the air pump is in communication with the air sack, the PH sensor is arranged on an inner wall of the stomach tube at a distance of 40 cm away from a foretooth, and the control circuit is connected to the air pump and the PH sensor, respectively. The stomach tube of the present invention uses the PH sensor and the pressure sensor to monitor the PH value of the esophagus and the pressure of the air sack in real time, so as to accurately detect the occurrence of stomach esophagus regurgitation each time in advance, thereby avoiding the possibility of aspiration caused by regurgitation and the recessive pneumonia caused thereby; meanwhile, the present invention adopts a real-time control manner to automatically start the expansion of the air sack, thereby avoiding the damage to the esophageal mucosa caused by the long-time compression of the air sack on the esophagus, and reducing the substernal discomfort of a user. As a stomach tube for preventing aspiration, the present invention can be widely applied to the field of medical instruments.

Disclosed is an NGT system, the system comprises a nasogastric tube having a diameter and length configured to pass through an esophagus such that the lumen of the NGT maintains fluid communication with a portion of the digestive tract, and a digestive tract sensor operatively associated with the NGT, the digestive tract sensor configured to sense from inside the body and transmit signals in response to one or both of conditions relating to nourishment states of the digestive tract, and positioning of the NGT.

An enteral feeding tube capable of delivering nutrients and/or medications to a patient at multiple points in the gastrointestinal tract and/or aspirating the gastrointestinal tract, comprising two or more channels each with at least one opening, said channels running parallel to the other until one channel ends, each channel keeping the fluid separated from the other channel, said channels being open at the proximal end and closed or open at the distal end and each channel having one or more perforations of same or variable size.

An apparatus for coupling radiation into and out of an optical fiber includes an optical element, a radiation system and a sensor system. The optical element is for coupling radiation into and out of the optical fiber. The radiation system produces input radiation, so that the input radiation is at least partially received by the optical element. The sensor system is for receiving output radiation from the optical element and operates to generate a signal indicative of at least one characteristic of the output radiation. The optical element, the radiation system and the sensor system are generally co-axial and the radiation system and the sensor system are both disposed on the same side of the optical element.

Devices and methods to measure gastric residual volume (GRV) are described where at least one additive component (a GRV indicator) may be dispersed in a body lumen such as a stomach. The GRV indicator may changes a physical (chemical, electrical, thermal, mechanical, optical, etc.) characteristic within the stomach by a measureable degree. This degree of change and/or the rate of return to the previous state, may be used to determine the GRV of a patient. The determined GRV can also be used to automatically or semi-automatically control the patient's feeding rate and/or volume and/or frequency to adequately nourish the patient but avoid complications. The physical characteristic(s) may also be used to detect that the feeding catheter or tube is in the correct location (ie stomach vs lung or esophagus.

Intelligent systems are disclosed for monitoring of enteral feeding pumps. The systems include a structure with a pivot mechanism, a fluid pump, a force-responsive electrical component, and an optional computing device. The pivot mechanism moves in response to force. The fluid pump moves feeding fluid, and the force-responsive electrical component changes electrical properties in response to force and alters resistance in the presence of an obstruction. The optional computing device can transmit an alert to a healthcare provider, for example, via smartphone. The force-responsive electrical component provides an electrical response in proportion to tension on a conduit and decreases resistance when there is an obstruction in the conduit. The systems sends an alert signal when the electrical response indicates an obstruction in the conduit.

Disclosed is an NGT system, the system comprises a nasogastric tube having a diameter and length configured to pass through an esophagus such that the lumen of the NGT maintains fluid communication with a portion of the digestive tract, and a digestive tract sensor operatively associated with the NGT, the digestive tract sensor configured to sense from inside the body and transmit signals in response to one or both of conditions relating to nourishment states of the digestive tract, and positioning of the NGT.

The invention relates to a truncated feeding tube comprising a first tube, a second tube, and a joint element. One terminal of the first tube and the second tube is removably connected to the two terminals of the joint element. A patient can connect the first and second tubes by the joint element or remove the second tube. Since the joint element can be separated from the first and second tubes, the joint member can be simply replaced when it is damaged without replacing the first or second tube. A positioning member is disposed on a front portion of the second tube, so that an endoscopic technology can be used to clamp the positioning member and the inner wall of the stomach or the duodenum by a hemostatic clip, and the front portion of the second tube is positioned in the stomach or the duodenum to avoid sliding displacement.

Disclosed is an NGT system, the system comprises a nasogastric tube having a diameter and length configured to pass through an esophagus such that the lumen of the NGT maintains fluid communication with a portion of the digestive tract, and a digestive tract sensor operatively associated with the NGT, the digestive tract sensor configured to sense from inside the body and transmit signals in response to one or both of conditions relating to nourishment states of the digestive tract, and positioning of the NGT.
