Abstract:
1. A blood pressure measuring apparatus comprising: an inner cuff to be inserted into an ear hole, and an outer cuff to be positioned outside a tragus; holding means for holding said inner cuff and said outer cuff; pulse wave detecting means incorporated into at least one of said inner cuff and said outer cuff to detect a pulse wave signal from blood flowing through a blood vessel; pressurizing/depressurizing means for pressurizing and depressurizing said inner cuff and said outer cuff by using a fluid, after said inner cuff and said outer cuff clamp the tragus; a tube connected from said inner cuff and said outer cuff to said pressurizing/depressurizing means to supply the fluid; pressure detecting means connected to said tube to detect pressures of said inner cuff and said outer cuff; and blood pressure measurement control means for measuring a blood pressure value from the pulse wave signal, wherein said holding means comprises; a shape part to be installed in a space between an auricular concha and an antihelix, a first protrusion extended from said shape part such that said first protrusion is directed towards the ear hole, a second protrusion extended from said shape part such that said second protrusion is nearly right-angled with respect to said first protrusion and said second protrusion steps over the tragus, an integral member having an ear hook that is extended from said shape part, said ear hook being integrally made with said integral member or made as an independent member, wherein said integral member supports said inner cuff at an end portion of said first protrusion, said integral member fixes a support member at an end portion of said second protrusion, said outer cuff is attached to said support member through a clamping width adjustment part that makes a clamping width adjustment against the tragus possible, and said outer cuff is made of a first outer cuff and a second outer cuff, said first outer cuff and said second outer cuff are fixed to a cuff member having a channel communicating said tube, such that said first outer cuff and said second outer cuff are located in the up and down directions with respect to the tragus, said cuff member is attached at an end portion of said support member through said clamping width adjustment part.
