  • Publication number: 20050143669
    Abstract: An electrode 4 for detecting a biological signal and a loop antenna 3 are integrally mounted on a support 2 placed on the surface of a living body and a transmitter 5 is placed on the support 2. A biological signal detected on the electrode 4 is input through a connector 11 to electric circuitry 10 of the transmitter 5 and an electric signal processed by the electric circuitry 10 is output through connectors 12 and 13 to both ends of the loop antenna 3 from which the biological signal is emitted to a receiver. At this time, the opening face of the loop antenna 3 is in a direction almost perpendicular to the surface of a living body for improving sensitivity.

    Abstract: A conductive composition for a biological electrode is capable of reducing the impedance between the electrode and the skin. A conductive gel composition for a biological electrode which is capable of electrically and physically connecting a living body to an electrode element and is composed of at least the following components: (1) a radical-polymerizable unsaturated compound; (2) a moisturizer serving as a plasticizer and functioning to supplementing and promoting the physiological humidifying function of the horny layer; (3) a polymerization initiator; and (4) a crosslinking agent. This moisturizer serves also as a plasticizer and, furthermore, elevates the moisture content in the horny layer at the application of this composition. The above-mentioned composition may further contain a plasticizer selected from among polyhydric alcohols, amines and ethers.

  • Publication number: 20030135088
    Abstract: A core 5 is composed of a J-shaped front core portion 1, a J-shaped rear core portion 2, a U-shaped left core portion 3, and a U-shaped right core portion 4. These core portions 1 to 4 have one-side end portions which are substantially directed in one and the same direction and which are fixed to one another to thereby form a center portion 6. A coil 7 is wound on the center portion 6. The core 5 is attached to a core support member attached closely to a patient. In use, the coil apparatus is made close or near to the patient. When the coil 7 is supplied with a pulse current, pulse-like magnetic flux is generated in the purdendal nerve and pelvic floor muscle group of the patient so that an eddy current is induced. The patient in the region where magnetic flux is generated and an eddy current is generated, is stimulated sufficiently, so that urinary incontinence treatment is performed.

  • Publication number: 20010031906
    Abstract: A method for magnetically stimulating biological body to make treatment or diagnosis by applying a time-varying magnetic field to nerve, muscle or disease part, wherein alternate frequency, inductance, pulse width, peak value of current, and stimulation frequency are set appropriately for the disease part, and a litz wire coil is used to produce the time-varying magnetic field. Hence, the effective A.C. resistance with the skin effect can be reduced and the power consumption efficiency can be increased. Moreover, the heat generation of coil can be decreased. Also, a magnetically stimulating device uses acoustic insulation or noise absorbing material for reducing noise caused by contact between wound coil parts.
