The invention relates to a nasogastric tube (100) comprising a nasogastric tubing (102) having first and second ends (102a, 102b), a power supply part (106) located at or adjacent the first end, and a transducer part (104) located at or adjacent the second end for transmitting or receiving an ultrasound based signal. Also disclosed is a positioning system comprising the said nasogastric tube, and a control module comprising an at least one detection portion and a processor.

This disclosure includes intraluminal tubes comprising: an elongated tube (e.g., having a proximal portion, a distal portion configured to be disposed inside of an internal cavity of a patient, and a sidewall defining a lumen extending from the proximal portion to the distal portion, the distal portion defining one or more openings in fluid communication with the lumen) and a plurality of deployable tines, each coupled to the tube and disposed outside the sidewall of the distal portion, where each tine is movable from a collapsed state to a deployed state in which a portion of the tine extends laterally away from the distal portion of the tube. In some of the present intraluminal tubes, the sidewall of the distal portion defines a plurality of longitudinal grooves, and each tine is disposed in a different one of the grooves when the tines are in the collapsed state.

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.

An enteral feeding adapter suitable for use with a plurality of infusion sets includes an outer body component made of a flexible material and containing a feeding port for receipt of a distal connector of an infusion set. A rigid body insert is seated within an internal recess of the outer body component and defines a proximal section of the feeding port. The insert includes a first continuous radial seal barb that engages the flexible material of the outer body component, and a plurality of separate and circumferentially spaced radial second seal barbs distal to the first seal barb that engage the flexible material.

A gastrojejunostomy tube may comprise a jejunal tube, gastric tube, and a balloon tube. The jejunal tube may comprise a port at a proximal end and an opening at a distal end. The gastric tube may comprise a port at a proximal end and an opening at a distal end. The gastric tube may be operably, fixedly coupled with the jejunal tube to form a tubular portion of the gastrojejunostomy tube. The balloon tube may comprise a port at a proximal end and a balloon at a distal end, and may be sized to dispose the balloon in the stomach of the target patient. The balloon tube may be selectably removable from the tubular portion of the gastrojejunostomy tube such that the tubular portion remains in the target patient and the balloon tube is removed from the target patient and replaced by another balloon tube.

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.

An endotracheal tube apparatus according to an example of this disclosure includes a brace for attachment to a patient's face, a support extending from the brace and including a groove for receiving an endotracheal tube. A clamp surrounds the support and the endotracheal tube. The clamp is comprised of a polymeric material

Devices, systems, and methods for guidewire placement for a gastrostomy tube are described herein. A system can include an elongated tube, an inflatable member, and a guidewire assembly. The elongated tube can have a first end, a second end, and can define a lumen. The inflatable member can be coupled to the first end of the elongated tube and can be fluidically coupled to the lumen such that the inflatable member can receive fluid via the lumen. The guidewire assembly can include a guidewire having a first end and a second end. The first end of the guidewire assembly can include a coupling member, the coupling member configured to couple to the inflatable member such that translation of the elongated tube translates the guidewire assembly.

One or more techniques and/or systems are disclosed for a gastrostomy tube having a proximal portion and a distal portion with at least one lumen extending therethrough. The proximal portion includes first, second, and third ports that are each operably coupled to the proximal portion with the first port configured to provide for suction of contents from a patient's stomach, and the third port configured to provide fluid to an inflatable balloon. The distal portion includes a plurality of first openings configured to transport contents to and from the patient's stomach, at least one second opening configured to cooperate with the second port to provide sump-type function, and a curved portion having a gradual bend of approximately 45°-135°. The curved portion directs a distal end of the tube radially outward and away from a longitudinal axis of the tube.

Method for ascertaining and setting a filling volume of a balloon of a catheter, which is placed in the esophagus of a living being, wherein the balloon is filled and/or emptied using a fluid. According to the invention, the balloon is filled and/or emptied step-by-step using at least two volume steps, a pressure difference between a pressure at the end of an expiration (Pmin) and a pressure at the end of an inspiration (Pmax) is determined for at least two volume steps, a relative pressure difference between Pmin and Pmax is determined, a border range is defined on the basis of the relative pressure difference, and an optimum filling volume is ascertained in consideration of the border range.
