Abstract: Provided is a biological information detection device capable of restraining noise from being mixed with a signal relating to biological information. A biological information detection device includes an electrode pad that is able to detect a signal (bioelectric signal) relating to biological information of a subject (for example, a fetus in a mother's body), a connector that is connectable to the electrode pad, and a cable that is connected to the connector and is able to transmit the signal. The electrode pad and the connector are provided with fixing members and that are attachable to and detachable from each other, respectively.

Abstract: An adhesive hydrogel has low contact resistance against the body surface and excellent conformability and adhesiveness to the body surface, so that noise generation can be reduced. Such adhesive hydrogel enables measurements of weak fetal heart rate signals. The adhesive hydrogel includes a polymer matrix prepared by crosslinking-copolymerization of an acrylamide derivative, which is a nonionic polymerizable monomer including a polymerizable carbon-carbon double bond in a molecule, and polyfunctional (meth)acrylamide, which is a crosslinkable monomer comprising 2 or more polymerizable carbon-carbon double bonds in a molecule, water, a polyvalent alcohol, and an electrolyte salt, wherein a laminate of the adhesive hydrogel with an Ag/AgCl sheet exhibits the impedance of 1Ω to 100Ω at the frequency of 0.1 Hz measured in accordance with the method of ANSI/AAMI EC12:2000, and the dynamic elastic modulus G′ at the frequency of 1 Hz measured at 25° C. and dispersed frequencies is 1.0×103 Pa to 1.0×104 Pa.

Abstract: A pad for electrodes (1) including a first conductive adhesive sheet (2) for connection with an electrode, a second conductive adhesive sheet (4) for connection with another electrode, the second conductive adhesive sheet positioned to be spaced apart from the first conductive adhesive sheet in a planar direction of each conductive adhesive sheet, and a base (10) supporting the first conductive adhesive sheet and the second conductive adhesive sheet. At least one surface of each of the first conductive adhesive sheet and the second conductive adhesive sheet is exposed, and each of the first conductive adhesive sheet and the second conductive adhesive sheet has a thickness compressibility of 10% or less and a thickness recovery ratio of 95% or more. The base is a non-electroconductive base having a water absorption capacity of 1 to 1.5 times, and the pad has a moisture permeability of 1,000 g/m2/24 h or more.
