Abstract: A wearable fluid delivery system comprising a single-use device with a tube, a pump, and a nutrition container with a fluid. The system further includes a module including a processor, a battery, and an electric motor with an output member. The processor is configured to operate the electric motor. The single-use device is releasably coupled to the module such that the output member is coupled to the pump when the single-use device is coupled to the module, and the output member drives the pump to cause the fluid to travel through the tube.

Abstract: The embodiments herein are directed to a portable liquid delivery system that incorporates an immersion driving pump mechanism(s), an administration reservoir, a user interface, and a wearable and/or portable accessory. The wearable accessory serves to house the components of the system and is to be worn on the user's body. In some cases, the system may be used to deliver nutritional formula for the treatment of patients on an enteral nutrition regimen. The apparatus described facilitates telehealth, training, and predictive processes to facilitate maximal therapeutic outcomes.

Abstract: The present invention is an enteral nutrition gastrostomy access device. A permanent or semi-permanent stoma liner is adjustably positioned within a stoma channel extending through a patient's abdominal and stomach walls. The stoma liner is characterized by an adjustable bladder capable of applying variable torsional force to one or more pinch points along the interface between the stoma liner and the stoma. The stoma liner is configured to receive a plug with a central threaded channel, into which a cap or enteral feeding device may be wholly or partially inserted. The central threaded channel is characterized by requiring application of a linear push force to apply but requiring application of both a linear pull force and a torsional force to remove.

Abstract: A urethane wheel including a hard urethane hub formed with a rim facing radially outward, and including stand-off ribs spaced equidistant thereabout. The stand-off ribs having centering notches opening radially outward. A thin wall polyurethane annular bladder with an interior annular stand-off skirt facing radially inward, contacting the centering notches of the stand-off ribs, and cooperating to position the bladder both radially and axially about the rim. The tire body is formed of soft polyurethane which surrounds the rim, encapsulates the bladder creating and integral cavity, and forms a contoured surface. A method of manufacturing the wheel which includes selecting a pressurized annular bladder, locating the bladder both axially and radially about the rim, forming a concentric bridge space having axial communication channels between the rim and bladder, and then pouring liquid urethane in a mold to form the tire.

Abstract: The present invention is a pre-pressurized in-line skate wheel which is capable of being pressurized at low levels and which further includes an integral bladder device having an annular tube and three bladder rods which are in fluid communication with respect to each other. The wheel is configured with a rigid polyurethane hub formed with a drop center and further having a pair of radially extending flanges with three pairs of axial openings. The hub is further formed with three radially projecting spokes. The tire body surrounds the bladder device and is constructed of a generally more resilient polyurethane which bonds to the hub, flanges and bladder. The method of manufacture utilizes blow molding techniques for the bladder device which includes a post vulcanization chlorine bath. The tire body is formed using liquid thermoset polyurethane poured into an open cast mold.

Abstract: An in-line skate wheel having a shaped foam core which cooperates with load bearing side walls to dictate degrees of flexure of such walls in response to loading thereof from different directions. The wheel structure includes a polyurethane tire body which encapsulates a foam mandrel and a hub.

Abstract: A skate wheel including a hard urethane hub formed with a drop center between radially projecting guide flanges, and including stand-off ribs disposed in equidistant spaced relation thereabout. Pairs of centering fins are spaced axially along a number of stand-off ribs thereby forming a central groove along the drop center. An annular bladder with an interior annular stand-off skirt is nested within the centering fins and concentric with the drop center. The wheel body is formed of a soft polyurethane and surrounds the drop center and encapsulates the annular tube, thereby forming a contoured surface. A method of manufacturing the wheel that includes selecting a welded seam annular tube, pre-pressurize it and then further pressurize it through the exothermic reaction by pouring liquid urethane in a mold to form the tire.

Abstract: A pre-pressurized in-line skate wheel including a hard polyurethane hub having a drop center formed between radially projecting guide flanges formed with axially projecting windows as spaced equidistant thereabout in an annular array. A bladder device includes a plurality of pressurized hollow cross rods nested at their opposite ends in such windows and surmounting on their radially outward sides a pressurized annular tube arranged concentric with the drop center. A soft polyurethane wheel body is formed in such drop center and projects radially outwardly to encapsulate the annular tube and form an elliptical annular tread surface. The method of manufacturing the tire includes blow molding the cross rods and the annular tube and pressurizing them to the desired individual pressures so that the resultant tire will exhibit the combined benefits of polyurethane cushioning and shock absorption associated with compressible gases.

Abstract: A pneumatic in-line skating wheel having a tire body and central hub chemically bonded during a polyurethane casting process and further including an annularly encapsulated air bladder centrally spaced within the tire body to provide shock absorption. The bladder in one embodiment is in communication with a valve for inflation and deflation thereof such that the overall tire resiliency may be adjusted, enabling adjustable performance characteristics of the wheel. One embodiment of the valve incorporates a resilient core within a rigid barrel and stretchable to allow an inflation needle to stretch the core and drive a poppet off a seat at the interior end of the barrel.

Abstract: A pneumatic in-line skating wheel having a tire body and central hub chemically bonded during a polyurethane casting process and further including an annularly encapsulated air bladder centrally spaced within the tire body to provide shock absorption and inflation/deflation means such that the overall tire resiliency may be adjusted, enabling adjustable performance characteristics of the wheel.

Abstract: A skate wheel hub assembly incorporating confronting hub rims cooperating to form at their radial outer extremities a V-shaped tire seat. The tire seat supports an elastomeric tire having a rigid mounting ring projecting radially inwardly. The mounting ring is locked between the confronting rims to eliminate relative movement between the tire and the wheel hub. In one form, the bearing assemblies may be offset in staggered relation on alternating opposite sides of a longitudinal skate center line.
