A gastric probe, which can be inserted through the nose of a patient, includes a hose for nasoenteral feeding of the patient and/or for discharging gastric juice. An extraction tube is secured to the hose and has, at a distal end, an extraction section which includes a plurality of openings. The extraction section, when inserted, is placed in the pharynx of the patient in order to extract saliva from the pharynx.

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.

A temporary tube for placement within a patient 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 along at least a portion of the distal end portion toward a distal end. The lumen may increase in cross section to the distal end, along an entirety of the distal end portion, from the proximal end portion to the distal end, or along an entirety of the tube. An outer cross section of the tube is uniform along at least a portion of the proximal end portion of the tube, or the outer cross section of the tube may be uniform from a proximal end of the tube along at least a portion of the proximal end portion of the tube. The tube may include at least one vent positioned in the distal end portion.

A nasogastric tube includes an outer tube and an inner tube. The outer tube has a receiving space and at least one opening, the receiving space is formed within the outer tube, and the opening is connected to the receiving space and formed at a sidewall of an end of the outer tube. The inner tube is longitudinally mounted in the receiving space to pass through the end of the outer tube and has an accommodating space and at least one through hole. The accommodating space is formed within the inner tube, and the through hole is connected to the accommodating space and formed at a sidewall of the inner tube passing through the end of the outer tube.

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.

A feeding tube aperture supported and aligned with a feeding tube opening in an abdominal wall of a patient, including a base having a first end surface transverse to an axis of the base and a feeding tube, a second opposed end surface, a central feeding tube passage extending between the first and second end surfaces, a plurality of vent passages around the feeding tube passage and extending between the first and second end surfaces, a hollow, cylindrical feeding tube support extension centered on and extending outwardly from the feeding tube passage to support and align the feeding tube aperture, and a plurality of spaced apart resilient spacers extending outwards from the second end surface. The plurality of spaced apart resilient spacers resiliently space the second end surface from the abdominal wall and form a plurality of air passages to allow a flow of air around the abdominal wall and the feeding tube opening.

A gastric feeding tube and method of use where the tube is of sufficient length for insertion into an esophagus of a subject via the nose or mouth. The gastric feed tube comprises a tube having a distal portion, a middle portion and a proximal portion, an outer surface and an inner surface forming a wall of the tube having a thickness and wherein the wall of the tube defines a lumen of a defined geometry, the lumen having an opening at a distal end of the tube for positioning in a stomach or jejunum of the subject and an opening at the proximal end of the tube for positioning outside of the nose or mouth of the subject wherein the lumen extends longitudinally through the tube connecting the opening at the distal end of the tube and the opening at the proximal end of the tube. The defined geometry of the lumen has a transverse major axis and a transverse minor axis that are perpendicular and wherein a portion of the inner surface of the wall of the tube along the transverse major axis comprises a rib that protrudes into the lumen and thickens the portion of the inner surface of the wall of the tube. The rib prevents the tube from fully collapsing and blocking the lumen when the tube is in use under normal conditions.

A system for administering nutritional fluids to a patient, including suctioning or aspirating fluids from stomach, performing gastric decompression, and containing gastric reflux. An exemplary system includes a Y-connector, a multiple lumen tube positional in the patient's gastrointestinal track, and an anti-reflux valve for controlling the flow of gastric/reflux material from the system.

A gastric tube temperature sensing apparatus for use during gastric or surgical procedures on a patient includes a gastric tube, such as an NG or OG tube, having a proximal end opposite a distal end and defining a tubular configuration. The gastric tube includes a flexible construction and defines a plurality of spaced apart openings proximate the distal end. An esophageal temperature device includes a temperature sensor situated in the gastric tube proximate the distal end thereof and a temperature monitoring element operatively connected to and displaced from the temperature sensor. The temperature monitoring element is situated external from the gastric tube and in communication with the temperature sensor, such as by wires. The temperature monitoring element may be electrically connected to a vitals monitor or the like. The apparatus includes an adapter for coupling a proximal end of the gastric tube to another device such as a suction pump.

A hub component for a vented connector including a generally elongate cylindrical body having a first end and a second end. The first end of the hub component includes one or more fingers or clips for engagement with one or more vents of the vented connector. The second end of the hub component can be configured for compatible engagement with a carbon dioxide detector.
