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.

Conductive composition for biological electrode

A biological electrode includes an electrode element having electroconductivity with respect to a living body, the biological electrode used by disposing said electrode element at a predetermined position, and the electrode element being made of biodegradable material.

Biological electrode

A core ( ) is composed of a J-shaped front core portion ( ), a J-shaped rear core portion ( ), a U-shaped left core portion ( ), and a U-shaped right core portion ( ). These core portions ( to ) 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 ( ). A coil ( ) is wound on the center portion ( ). The core ( ) 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 ( ) 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.

Coil apparatus for urinary incontinence treatment

A core ( ) is housed in a box ( ) in which a box upper board ( ) is electrically insulative and nonmagnetic. The core has front and rear side legs ( ) directed toward the box upper board ( ). A coil ( ) is wound around the core ( ). An air way ( ) is formed in a box bottom board ( ). A blower ( ) is attached to the air way. Other air ways which cooperate with the air way ( ) to form air pathways passing over the coil ( ) are formed in box side boards ( ). Pulse current or alternating current is supplied to the coil ( ) to generate magnetic fluxes toward a region from a front of the urethral orifice to a rear of the anus, so that urinary incontinence is treated by eddy currents induced in the living body.

Air-cooling device for coil for urinary incontinence treatment

A seat face part,of a chair,is provided with a stimulating coil,. A projection,is made on the top of the stimulating coil,. When a treated patient sits in the chair,, the anus of the treated patient is placed on the top of the projection,, whereby the treated patient can be made to sit at the optimum position for urinary incontinence treatment relative to the stimulating coil

Urinary incontinence treatment instrument

A magnetic stimulus type urinary incontinence treatment coil apparatus for generating flux for generating eddy current in a physiological body by providing a coil having an upper surface curved in a concave manner at least in a longitudinal direction such that the coil is fitted to at least part of an area from a front face region of a urethra opening to a rear face region of an anus, the coil wound around the area; and a support for supporting the coil at a position at which the coil is fitted to a patient.

Magnetic stimulus type urinary incontinence treatment apparatus

A method for treating urinary incontinence which consists of delivering a train of current pulses through one or more magnetic stimulation coils to induce a train of magnetic flux pulses, which then induce an eddy current within the body, thereby to stimulate a group of pelvic floor muscles, the pudendal nerve, the external urethral sphincter, or the tibial nerve.
