  • Publication number: 20120161960
    Abstract: A body fluid absorption object wetting alarm method and an apparatus associated are revealed. A light wavelength sensor is disposed on a body fluid absorption unit for detecting wavelength of the body fluid absorption unit. After the body fluid absorption unit becoming wet, the wavelength thereof changes. Then warning signals are sent to the receiving and checking unit. Thus, a caregiver at a management end of the receiving and checking unit knows that the body fluid absorption object worn by a care recipient was already wet and there is a need to replace the wet body fluid absorption unit with a new one immediately.

  • Patent number: 7914753
    Abstract: An analytical system includes a working fluid, a uniform dividing unit and a separating unit. The working fluid includes a first component and a second component with different characteristics. The uniform dividing unit is utilized to uniformly divide the working fluid and relatively rotated with respect to a reference axis. Under a capillarity force as well as the result of Coriolis force and siphon force, the first component can be separated from the second component by the separating unit.

  • Publication number: 20050244809
    Abstract: A device for detections of one or more analytes in one or more samples is disclosed. The device can simultaneously detect multiple analytes in a sample or an analyte in a plurality of samples. The device has a plurality of wells formed thereon. Each of the well has a respective composition loaded therein, wherein each of the composition comprising a respective catalyst is encapsulated in sol-gel. In addition, a first fluorescent dye and a second fluorescent dye are encapsulated in the sol-gel or added to the sample(s) for detection and quantitation. The catalyst(s) interacts with or reacts with the specific analyte(s) in the sample(s) and causes a change(s) in spectroscopic property. The concentration of an analyte(s) is detected by comparing the normalized spectroscopic property to a standard curve. A method is also disclosed for the detection of one or more analytes in one or more samples by using the device.
