  • Patent number: 8444593
    Abstract: A peritoneal function testing method uses a ratio of MTACun/MTACc, calculated using MTACun and MTACc, as an index for a peritoneal function test, wherein MTACun is an overall mass transfer-area coefficient for urea nitrogen and MTACun is an overall mass transfer-area coefficient for creatinine. The use of MTACun/MTACc enables examination of the future peritoneal function of a patient (a mechanism of deterioration in peritoneal function). To be specific, MTACun and MTACc can be obtained by computing a Pyle-Popovich model. In addition, the peritoneal function testing method further calculates a permeability coefficient for cell pores (LpSC) and an overall permeability coefficient (LPS) from a Three-Pore Theory model while obtaining a ratio of LPSC/LPS calculated using the LPSC and the LPS. The LPSC/LPS ratio and the MTACun/MTACc ratio can be used as indexes for the peritoneal function test.

  • Patent number: 8303532
    Abstract: A peritoneal function testing apparatus tests the peritoneal function of a dialysis patient easily and with high accuracy. Standards of four kinetic parameters (CCr, Kt/V, MTACu, and MTACc) available in a definite dialysis guideline are computed in accordance with a relational expression, and a curve showing the relation between MTACu/c and the drained fluid volume is indicated in a graph together with the PET data of the patient which has been prepared separately. Thus, the peritoneal function can be evaluated based on the relative position of the patient's data and the curve showing the standard values in the graph.

  • Patent number: 8123715
    Abstract: The present invention is a peritoneal dialysis and hemodialysis hybrid-remedy planning method using an index that is shared by both peritoneal dialysis and hemodialysis and indicates an effect of dialysis. To be specific, the index is M/C(0)/VB, which is obtained by dividing a ratio M/C(0)—where M is a removal amount of a solute for a fixed time period, and C(0) is a concentration of the solute in blood before the dialysis—by a patient's body fluid volume, VB. The present invention is capable of representing the dialysis effect of PD and HD as an integrated sum, and achieving concise and explicit PD and HD hybrid-remedy planning.

  • Publication number: 20110306378
    Abstract: A plurality of masters continuously receives data through a specific channel to detect whether a slave exists nearby. On the other hand, the slave transmits data for a given period through the specific channel by a trigger specified by a user. A master near the slave receives the data transmitted by the slave and recognizes that the slave exists nearby. After the recognition of the slave, the master performs carrier senses on channels other than the specific channel and transmits data for a given period through a channel on which a carrier does not exist. After the transmission through the specific channel, the slave receives a plurality of channels other than the specific channel to receive the data transmitted by the master.

    Abstract: The present invention provides thermoplastic resin molding fiber that is reinforced with natural fiber. The natural fiber is linen fiber to be twisted into spun yarns, and the spun yarns are pulled parallel in at least one direction and are molded integrally with a thermoplastic resin. The linen fiber is flax yarn (linen) fiber molded into the fiber thermoplastic resin molding by a film-stacking method in which a thermoplastic resin film is melted and compressed while having an equilibrium moisture regain. Consequently, the thermoplastic resin molding reinforced with a plant fiber of the present application poses no environmental problem, has a high strength, and has a uniform physical property.

  • Publication number: 20090271119
    Abstract: It is intended to provide a method whereby the peritoneal function of a dialysis patient can be tested by a relatively easy procedure and yet a high accuracy can be achieved compared with the existing methods, and an apparatus for the peritoneal function test by using the same. Standards of four kinetic parameters (CCr, Kt/V, MTACu, and MTACc) available in a definite dialysis guideline are computed in accordance with the relational expression (formula (7)). The curve showing the relation between MTACu/c thus obtained and the drained fluid volume is indicated in a graph together with the PET data of the patient which has been prepared separately. Thus, the peritoneal function can be evaluated based on the relative position of the patient's data and the curve showing the standard values in the graph.

  • Patent number: RE42390
    Abstract: In a sound signal playback machine and method thereof, predetermined high frequency components are extracted from sound signals SL to SC of a main channel by high frequency pass filters 21 to 25, and these high frequency components are respectively played back by speakers. At the same time, predetermined low frequency components are extracted from sound signals SL to SC of the main channel by low frequency pass filters. These low frequency components and sound signal SLFE exclusively used for the low frequency band are added to each other, and the thus obtained addition signal is played back by the speaker 66. In this case, the degree of the low frequency pass filters is set higher than the degree of the high frequency pass filters, and the high frequency component is delayed.
