    摘要： Superabsorbent polymer materials are provided including absorbent polymers having a fast vortex time, desirably about 10 seconds or less, and a stiffness index of at least about 0.7, as determined by test procedures described herein. The absorbent polymers can be modified to obtain a faster vortex time by a method including providing an absorbent polymer having a first vortex time, absorbing water with the absorbent polymer, freeze-drying the swollen absorbent polymer to remove at least a portion of the absorbed water, and obtaining a modified absorbent polymer having a second vortex time. The ratio of the first vortex time to the second vortex time is at least about 5, and desirably the modified absorbent polymer has a stiffness index of at least about 0.7.

    摘要： A distinctive absorbent article includes an absorbent core having multiple absorbent layers, wherein the absorbent layers interact in such a manner which preferentially locates absorbed liquid in an appointed, high saturation wicking layer. The localization of the liquid within this wicking layer increases the potential of this layer to move liquid through capillary action due to the higher saturation level and increased amount of liquid available. The intake capability of the absorbent system is maintained or improved over current systems by keeping a second layer of the absorbent system at low saturation levels through as many insults of the product as possible, while providing optimum intake performance through appropriate control of the composite properties. The low saturation in this layer provides void volume for the incoming insult as well, as a high permeability, thus increasing the intake rate of the absorbent system as a whole, but the structure of the low saturation layer is also balanced to provide an appropriately high level of capillary tension to provide enough control of the liquid to stop leakage from occurring. This low saturation layer is used in addition to a surge material and provides intake functionality in addition to that provided by the surge material. In particular aspects of the invention, the body side layer of the absorbent core does not extend over the entire surface of the overall absorbent core, therefore is not used as the high saturation, wicking layer, but as the intake layer. This arrangement also allows the intake layer to be in direct contact with the incoming liquid, therefore allowing for more immediate access and improved intake function.

    摘要： Systems and methods for monitoring nutritional uptake of an individual are disclosed. The method can include monitoring microflora intestinal gas concentration levels associated with a patient and adjusting the volume of nutrient provided by the patient with an artificial feeding device based at least in part on the microflora intestinal gas levels associated with the patient. A microflora intestinal gas sensor can be used to monitor the microflora intestinal gas associated with the patient. The microflora intestinal gas sensor can monitor the microflora intestinal gas in a patient's exhaled breath or in the patient's digestive tract. The microflora intestinal gas sensor be included as part of an enteral feeding system at the distal end or outside end of an enteral feeding tube. Systems and methods for monitoring nutritional uptake of an infant based on microflora intestinal gas levels associated with the infant are also disclosed.

    摘要： Presented is a method for quantifying breastfeeding between a mother and a baby, the method including measuring a physiological volume indicative of stomach fullness volume for the baby; setting a signal threshold value of the physiological volume to correspond to a stomach level that is less than or equal to the stomach fullness volume; obtaining an objective measurement of the physiological volume indicative of a level of fullness of the baby's stomach; and providing an indication to the mother when the objective measurement equals or exceeds the signal threshold value.
