  • Publication number: 20210041448
    Abstract: A problem to be solved by the present invention is to provide a method of assisting diagnosis of the health condition of a subject by correcting variation in an amount of a collected disease marker, which is caused by variation in the skin barrier function of the subject, and acquiring information reflecting the health condition of the subject accurately, and to solve the problem, the present invention provides a method of assisting diagnosis of a disease in a subject using a disease marker and a reference marker, the method including: applying, to a skin surface of the subject, a sheet capable of generating an attractive force due to electrostatic interaction between the sheet and each of the disease and reference markers; detaching the sheet from the skin surface; measuring the amount of each of the disease and reference markers that are attached to the sheet; and acquiring information on the disease in the subject based on a value obtained by correcting the measured amount of the disease marker with the me

  • Patent number: 8037564
    Abstract: The air cells are attached detachably to the base members. By this, it is possible to set up the size or the arrangement of the air cells. For example, in a hospital, it is possible to change easily and inexpensively the air cells on a bed according to the patient's height, the body shape, the state, or the condition of affected part. Thus, it is exceedingly advantageous for dispersing the pressure added to the body.

  • Publication number: 20100030177
    Abstract: [Problems] To provide an absorbent article that is favorably effective in body pressure dispersion [Means for Solving Problems] An absorbent article X1 having an absorber 3 in which plurality of absorbent cores 3A, 3B each including a fiber base material 31 and an absorbent polymer 30 are layered in such a manner that the polymer 30 swells by gelation due to liquid absorption and expands up to one surface F of the fiber base material 31 through inter-fiber gaps thereby to form a polymer layer 40 on the fiber base material surface F while the absorbent polymer expanding surfaces of adjacent absorbent cores are opposed to each other.

  • Publication number: 20090106905
    Abstract: There is realized a configuration in which, even when pressure is concentrated, the pressure can be adjusted based on accurate and precise detection of pressure distribution, thereby providing sleeping comfort. An air mattress device has a sensor that detects the distribution of pressure applied to an elastic sheet, by means of light emitting parts and light receiving parts of optical fibers uniformly distributed in the elastic sheet. Based on pressure distribution detected by the sensor, the air mattress device adjusts the amount of gas filled in an air mattress. The sensor can be disposed above the air mattress of the air mattress device.
