3928 results about "Feeding tube" patented technology

A feeding tube is a medical device used to provide nutrition to people who cannot obtain nutrition by mouth, are unable to swallow safely, or need nutritional supplementation. The state of being fed by a feeding tube is called gavage, enteral feeding or tube feeding. Placement may be temporary for the treatment of acute conditions or lifelong in the case of chronic disabilities. A variety of feeding tubes are used in medical practice. They are usually made of polyurethane or silicone. The diameter of a feeding tube is measured in French units (each French unit equals ⅓ mm). They are classified by the site of insertion and intended use.

Atomic layer deposition apparatus

An atomic layer deposition (ALD) apparatus is, suitable for thermal ALD and plasma-enhanced ALD of conductive and non-conductive films. The ALD apparatus can maintain electrical insulation of a gas dispersion structure, such as a showerhead assembly, which acts as an RF electrode to generate plasma inside a reaction chamber while depositing electrically conductive films in the reaction chamber. Fine tubules of micro-feeding tube assembly prevents plasma generation in them and reactive gases each have separate flow paths through the micro-feeding tube assembly. Process gases out of the micro-feeding tube assembly enter narrow grooves of a helical flow inducing plate and form helical flows which mix well each other. Symmetrically mounted pads on showerhead assembly and flow guiding plate maintain a symmetrical gap through which an inert gas flows continuously to keep reactive gases outside the gap and unwanted film deposition in the gap. Longer operating time before maintenance (cleaning) and thus higher productivity can be achieved.

Atraumatic gastrointestinal anchor

The present invention relates to methods and articles for anchoring within a natural bodily lumen. An anchor is adapted to provide differing radially-outward forces along its length, a securing force and a transitional force. Production of these forces can be controlled by varying a physical property of the anchor, such as its stiffness, thickness, or shape. For example, the stiffness of an elongated anchor can be varied from a relatively soft value at its proximal and distal ends to a relatively stiff value at its center by varying the diameter of wire forming the anchor, thereby tailoring it to an intended application. Such force tailoring can be combined with external barbs and used to reliably anchor other instruments, such as feeding tubes and intestinal sleeves.

Hands free personal hydration delivery system

InactiveUS6283344B1Little suction effortReduce flow of fluidTravelling sacksTravelling carriersHigh elevationHands free
A hands-free personal hydration delivery system has a tubing assembly that has one end that detachably connects to a feed tube for a container of fluid worn on the back or torso of a user. The other end of the tubing assembly is coupled to a bite valve which is opened when manipulated by the user's mouth to allow fluid to be drawn by suction applied by the user, and is closed when not being manipulated so as to cut off fluid flow in an air-tight condition. An intermediate portion of the tubing assembly is mounted on the user's head or to the user's headgear at a position of higher elevation than the user's mouth. This allows fluid to be drawn to the elevated position and flow downward from there to the user's mouth by gravity feed. The fluid flow can then continue with little suction effort due to the gravity feed and siphoning effect of fluid from the container. The tubing can be mounted using retainer loops or other type of fasteners attached to a helmet, sports cap, head band bracket, headphone bracket, headband, or an earpiece worn by the user. The hydration delivery system is especially useful for bicycling, canoeing, mountain biking, kayaking, canoe paddling, and rowing environments.

Paintball loading device

An adaptive, force-fed paintball loading device capable of delivering paintballs to a paintball marker against the force of gravity is disclosed. The paintball loading device preferably includes a refillable compartment that is generally an oblong elliptical container holding a plurality of paintballs. Paintballs are able to flow through an opening in the lower portion of the compartment and in between two synchronously geared counter-rotating helical augers. The geometry of flutes on the counter-rotating augers causes the paintballs in the lower portion of the container to be engaged between the augers and then pushed along a channel between the augers and out through a feed tube, which is attached to a paintball marker. A DC electric motor is used to drive the augers. A speed reduction unit is employed to reduce the motor shaft speed to a level practicably used by the synchronously geared augers. A feedback control loop and dynamic coupling element are also employed to enhance the response of the loading system to changing rates of fire of the attached paintball marker. Input signals from sensors on the paintball marker and the paintball loading device may also be employed to enhance the responsiveness of the paintball loading device to the demands of the paintball marker.
