An apparatus for use in tube feeding has a cylindrical body provided with first opening and second openings connected by a flow channel. The body has a reagent, for determining a characteristic of fluid disposed in the body and a transparent window to view the reagent. In use, a first end of an internal feeding tube releasably engages with the first opening. The second, distal end of the feeding tube is disposed inside a patient. A second feeding tube engages with the second opening. The second feeding tube connects the apparatus to a bi-directional pump operable: to pump internal fluid from a reservoir, through the apparatus and into the internal feeding tube; and to pump fluid from the patient into the body of the apparatus. This allows a user to pump fluid from the patient into the body of the apparatus to react with the reagent.

A multifunction oxygen mask comprises a mask body and a gas delivery adapter. A nasal chamber is formed in the upper portion of the mask body. An access aperture is formed through and adjacent to a lower portion of the mask body. The access aperture permits access to the mouth of a patient. The gas delivery adapter includes a first end coupled to a gas delivery adapter aperture of the mask body. An oxygen supply port radially extends outward from the gas delivery adapter. The oxygen supply port includes an external inlet portion, an outlet portion positioned within the gas delivery adapter, and a diverter member adjacent to the outlet portion. The diverter member is configured to direct a flow towards the first end of the gas delivery adapter. A meter-dose inhaler port radially extends outward from the gas delivery adapter. The gas delivery adapter includes a nebulizer port.

Systems and methods for effecting bariatric procedures are disclosed. Each system includes an instrument, a control valve and, optionally, a suction controller. The instrument is in the form of an elongated, flexible sizing tube having a distal end portion including a plurality of apertures. The control valve enables suction to be applied to the patient's stomach via the apertures to drain gastric fluids and to bring adjacent portions of the patient's stomach into engagement the sizing tube to provide a visually perceptible delineation line along which a portion of the stomach may be resected, sealed and tested.

A nasogastric tube comprising at least one main lumen and at least one vacuum lumen comprising at least one suction port for sealingly drawing an inner wall of an esophagus thereagainst, said at least one suction port has a unique concave structure which substantially prevents tissue damage is provided.

A repositionable medical tube, such as an endotracheal tube, a nasogastric tube, or a nasojejunal tube, having an inflatable cuff with at least one divot region therein, the divot region having an outer diameter sufficiently smaller than an outer diameter of both a proximate cuff region and of a distal cuff region as to produce a discernibly-distinct ultrasonic image when scanned by an ultrasound sensor. The medical tube may be further provided with an ultrasonically-detectable coil or one or more ultrasonically-detectable markers having an identifiable geometric shape when the marker is visible using an ultrasonic probe.

A long, thin, flexible medical apparatus, a kit, and a method placing, confirming, and visualizing placement of a gastric tube. The apparatus comprises an elongate body portion, a handle, and a distal tip portion. An ability to insert and remove the body and distal tip portions in relation to the gastric tube over the length of the long, thin, flexible structure provides a positive indication that the lumen is not blocked, obstructed, or otherwise compromised over that length. pH indicator sensors and, additionally or alternatively, radiopaque markers may be retained by the distal tip portion. The pH sensors exhibit a verifiable color change in response to contact with a predetermined subject fluid. The radiopaque markers enable a determination with certainty of the location and orientation of the distal tip portion of the apparatus and of the distal portion of a gastric tube in which the apparatus is disposed.

The disclosure includes embodiments of an apparatus, a device, and methods to transform an infant feeding bottle into an infant gavage feeding apparatus. According to an embodiment, an infant gavage feeding apparatus can include an infant feeding bottle, a gavage milk delivery component, a retaining ring, and a cord component. In another embodiment, infant milk dual-delivery device to transform an infant feeding bottle to an alternate nipple feeding and gavage feeding apparatus includes a gavage milk delivery component, a retaining ring, and a nipple receiving component. The gavage milk delivery component and the nipple receiving component can be positioned in a branched or a stacked configuration. The device can include a flow closure component and a controller to transition the milk flow for a gavage feeding and nipple feeding. The device can include a funnel to allow milk in the nipple to flow back into the infant feeding bottle.

The stomach tube is a transparent conduit in the form of a plastic tube which is equipped with an optical fibre with illuminating external surface. Its internal end is placed in the section of the stomach tube for insertion in the patient's stomach. An external end for connection with a light source is provided outside the stomach tube in the section of the stomach tube remaining outside the patient's body. The conduit of the stomach tube in its interior includes a first channel which is a transport channel, and a second channel in which the optical fibre is located. The stomach tube is intended for use in bariatric surgery procedures, and in particular in the sleeve gastrectomy procedure.

A balloon catheter (100), suitable for delivery of a balloon to the stomach via application by the nose, the balloon catheter comprising a catheter (2) and one or more inflatable balloons (1) fixedly attached to the catheter. The balloons have an outer diameter from 4 to 7 cm, are made of a relatively hard material (e.g. durometer 70 to 100 shore A), and have an effective length of 7 to 18 cm or a total inner volume of 90 to 330 ml, when inflated by 0.2 psi. A system comprising the balloon catheter, and a pressure sensor for measuring a pressure of a fluid inside the balloon, and optionally a fluid pump for inflating and/or deflating the balloon, and a control unit for reading the pressure sensor and optionally for controlling the fluid pump.

A long, thin, flexible medical apparatus, a kit including such an apparatus, and a method for employing the apparatus to assist in placing a distal portion of a lumen of a gastric tube in a stomach of a mammal. The apparatus comprises an elongate body portion, a handle portion fixed to a proximal end of the body portion, and a distal tip portion fixed to a distal end of the body portion. An ability to insert the body and distal tip portions into the gastric tube over the length of the long, thin, flexible structure provides a positive indication that the lumen is not blocked, obstructed, or otherwise compromised over that length. pH indicator sensors may be retained by the distal tip portion to exhibit a verifiable color change in response to contact with a predetermined subject fluid, such as gastric fluid, lung fluid, or another bodily fluid.
