  • Patent number: 9174912
    Abstract: A primary object of the present invention is to provide a polylactic acid decomposition method that efficiently decomposes polylactic acid so that the polylactic acid can readily undergo degradation by a biological treatment such as methane fermentation. Specifically, the present invention provides a polylactic acid decomposition method involving a step of impregnating a polylactic acid-containing organic material with a treatment solution containing an organic acid salt and/or inorganic acid salt of an amine compound.

  • Patent number: 8626453
    Abstract: A blood glucose level information processing apparatus, method and program provide blood glucose values and blood glucose value information within a period or range desired by a user without imposing cumbersome operation on the user. The apparatus, method and program provide blood glucose values and blood glucose value information within a period or desired range by acquiring blood glucose levels measured by a blood glucose level measuring device and date/time of measurement at which the blood glucose levels are measured, displaying a line graph obtained by plotting the blood glucose values within a predetermined period. A slide bar can also be provided, for example on a graph display screen image, whereupon if the slide bar is moved, only the blood glucose values corresponding to a preceding period backdating in response to the amount of movement of the slide bar are plotted on a line graph along a time series.

  • Patent number: 6595948
    Abstract: The invention aims to provide a compact peritoneal dialysis apparatus using a disposable cassette integrally formed with a diaphragm and heating portion, in which a flow path can be switched quietly and a heating ability is high. By using a disposable cassette (8) integrally formed with a diaphragm, heating portion, and flow path switching portion, a predetermined amount of dialysis fluid is heated to a predetermined temperature with the heating portion. Clamps (111-118) for opening/closing a flow path switching portion are provided in order to form flow paths through which the heated peritoneal dialysis fluid is distributed into the peritoneal cavity of a patient almost continuously and is sucked and drained from the peritoneal cavity of the patient.
