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.

Improved feeding set connectors and cassettes are disclosed for use with peristaltic infusion pumps for safely delivering enteral nutritional fluids to a patient. The connectors provide an easy to use “pump-to-set” integration or “keying” system for specific reusable infusion pumps and their matching feeding sets, and can be utilized by medical professionals having various skill levels. The inventive feeding set cassettes can prevent accidental free flow of enteral fluids into a patient, even upon inadvertent release of the connector from the pumping mechanism.

Disclosed is a connector for connecting a sealed, flexible nutrition pouch to the hydration system of a user's protective mask, that allows the nutrition pouch to remain sealed until the user intends to consume the product inside of the nutrition pouch, enables resealing of the pouch after it has initially been opened, and allows connection of the nutrition pouch to the user's hydration system. The connector comprises a multi-piece body having an inlet end that may be manually attached to the outlet of the nutrition pouch without breaking the seal covering the outlet of the nutrition pouch. The connector likewise has an outlet end configured for attachment to an adapter on the user's fluid delivery system. Upon attachment of the adapter to the outlet of the connector, a piston inside of the connector is pushed toward the outlet of the nutrition pouch and breaks the seal over the outlet of the nutrition pouch, thus forming a flow channel for material in the nutrition pouch to flow through the connector and into the adapter and fluid delivery system for ultimate consumption by the user.

A nasogastric probe comprises at least one substantially flexible tubular element of elongated shape, provided with at least one main channel communicating with at least one feeding mouth of nutritive substances or the like, which is arranged at a first end stretch of the tubular element itself, and with at least one delivery mouth of nutritive substances or the like, which is arranged at a second end stretch opposed to the first end stretch and intended to be inserted into the patient's stomach passing through the esophagus; and it comprises pressure detecting means inside the esophagus comprising at least one pressure sensor associated with the tubular element and interposed between the feeding mouth and the delivery mouth.

A system for measuring cardiovascular data includes an elongate member having a channel, a first expandable member carried by the elongate member and movable between a collapsed state and an expanded state by adjustment initiated externally of a subject, a first sensor disposed on a surface of the elongate member, second and third sensors disposed on a surface of the first expandable, a first optical sensor located at a first location in relation to the distal end of the elongate member and configured for obtaining photoplethsmographic data, and wherein the first expandable member in its expanded state is configured to interface with the subject's larynx for delivery of at least oxygen gas into the respiratory system of the subject, and the second and third sensors are configured to contact tissue in proximity to the larynx when the first expandable member is in its expanded state.

A cartridge for delivery of a material therefrom which has a corrugated portion to allow for bending/extending to be applied to the device from which a material to be deposited can be dispensed. The bendability and extendibility allow for greater efficiency in use and application of the material into cavities, pockets, and/or crevices where one needs to deposit the material.

A catheter protection device and method for securing a catheter to a patient's body to prevent the unauthorized and possibly traumatic removal of a catheter. The device is thin, breathable and not easily removed by an agitated or mentally incompetent patient. The device is constructed of a base, adhesives, and a sleeve. The edges of the base each contain a section of adhesive wherein mid-portion of the base remains uncovered by adhesive. The open sleeve is permanently attached to an edge of the base. Once a catheter has been placed in an open sleeve, the sleeve will be folded such that the rear portion of the sleeve attached to the nearest edge of the base creating a closed sleeve surrounding the catheter. The catheter protection device may be placed against a patient's body with the adhesive edges of the base and an adhesive covered catheter sleeve adjacent to a patient.

Devices for cleaning a tube or clearing a blockage from a tube, such as an enteral feeding device are provided. The devices include an actuator and a syringe. The actuator is releasably attached to the syringe in a manner that allows the actuator to transition the syringe from a compressed position to an extended position, and vice-a-versa, without requiring the intervention of a user. A method of cleaning a tube or clearing a blockage in a tube is also provided. The tube cleaning device is filled with a liquid and the actuator pushes the liquid from the syringe into the tube when transitioning into a compressed position, and withdraws the liquid back into the syringe when transition into an extended position, causing the liquid to contact a blockage, and clear the blockage and/or clean the tube.
