In some embodiments a PEG feeding device includes a tube sized to bridge a channel between a stomach and an outer abdominal surface; an internal bolster, and an external bolster. Optionally the bolsters are connected to the tube. The internal bolster may be sized to resist movement out of the stomach through the stoma. The external bolster may be sized to resist movement into the stoma from the outer abdominal surface. The external bolster may include an underside which extends from the tube in a radial direction between the external bolster and the outer abdominal surface. The underside of the outer bolster may contact the outer abdominal surface at a distance from an external opening of the stoma. Optionally the distance between the internal bolster and the external bolster is adjustable. Optionally an angle between one or both of the bolsters and the tube is adjustable.

Systems and devices for providing readily accessible and unassisted oral hydration to a patient or other individual. A hydration system of the present disclosure may include a container for holding a quantity of liquid, a hydration tube extending from the container, and a hydration control valve through which a user may access the liquid by pushing or pressing on a lever. The hydration control valve may be, or be similar to, a pinch valve or bite valve arranged across a tube, such that by opening the valve, water may be permitted to flow through the tube. The valve may be arranged within a valve casing having a hydration tube coupling portion and a mouthpiece.

Adapters for a connector assembly for percutaneous tubing are provided. A male adapter (FIG. 22a, 1000) includes a connector fitting (1002) proximate a first end, the connector fitting configured to join to a connector for a tubing system or device, and a male connector (656) proximate a second end. The male connector includes a plug end with a fluid lumen defined therethrough, the plug end having a circumferential groove defined therein to receive a locking extension of a female connector sized to be received within the circumferential groove of the plug end to allow the female connector to rotate relative to and maintain axial engagement with the male connector when the locking extension is received within the groove. An adapter having a female connector (FIG. 24, 1300) is also provided.

A catheter having a selectively inflatable external balloon and an internal balloon, where the internal balloon is operable as a valve to control fluid flow through a channel.

The invention relates to an installation for producing a medical preparation, in particular for producing a preparation for parenteral nutrition. Liquids are transferred by means of the installation from a plurality of source containers to a target container. The installation comprises a receptacle with drivers for a valve block, wherein the drivers of the valves are arranged offset from one another.

Connector assembly (FIG. 4a) includes a shell (210), a connector body (230), and a plug (250). The shell (210) has a sidewall (212) defining an interior, a first shell end having a first opening (214) defined therein, and a second shell end having a second opening (216) defined therein, each of the first (214) and second openings (216) in communication with the interior to receive percutaneous tubing therethrough, the shell (210) further having an engagement portion. The connector body (230) has a first body end (234) and a second body end (236) with a tube lumen defined therethrough, the first body end (234) having a connector tip (237), the connector body (230) having an engaging portion to engage the engagement portion of the shell (210). The plug (250) has a first plug end and a second plug end with a fluid lumen defined therethrough, the first plug end having a plug tip (257) extending therefrom.

A computer-implemented method of adjusting enteral feeding of a patient by an enteral feeding controller, comprising: computing an estimate of energy expenditure of the patient based on oxygen measurements and carbon dioxide measurements of the patient, computing a target composition and target feeding rate for the enteral feeding according to the computed estimate of energy expenditure, when the target composition and target feeding rate differ from a current enteral feeding composition and feeding rate by a requirement, generating instructions for adjustment, by an enteral feeding controller, of the rate of delivery of the enteral feeding according to the target composition, wherein the receiving the oxygen measurement, receiving the carbon dioxide measurement, and computing the estimate of energy expenditure are performing iteratively for every first time interval, and the generating instructions for adjustment are performed for a second time interval that is larger than the first time interval.
