The present invention enables making uniform contact with the tragus using inner and outer cuffs, each of said inner and outer cuffs being comprised of a cuff memberconnected to a ductand a cuff bladderhaving a bodywhich is fixed onto said cuff member in an air-tight manner and can expand and contract, comprised in such manner in order to carry out accurate blood pressure measurement at any one given point in time without being affected by the pinch width of the tragus and depth to the tragus even with repeated mounting and removal from the ear auricle, and also comprised such that a lidof said cuff bladder forms a pressing surfacein a shape of a protrusion.

Blood pressure measuring cuffs and a blood pressure measuring device

A blood pressure measurement apparatus which can install cuffs at a tragus that has differences includes a holding memberhaving a shape partto be installed in a space between an auricular concha and an antihelix, a first protrusionextended from the shape part such that the first protrusion is directed towards the ear hole, a second protrusionextended from the shape part such that the second protrusion is nearly right-angled with respect to the first protrusion and the second protrusion steps over the tragus, an integral memberhaving an ear hook partthat is extended from the shape part, the ear hook is integrally made with the integral member or made as an independent member, inner cuffis supported at the end portion of the first protrusion, support memberis attached at the end portion of the second protrusion, cuffsare attached to the support member through a clamping width adjustment partthat makes a clamping width adjustment against the tragus possible.

Blood pressure measuring apparatus

This invention provides a blood pressure measuring apparatus capable of stably measuring the blood pressure in even the tragus while suppressing the degree of invasion. An attaching portion () of the blood pressure measuring apparatus has an inner cuff (), an outer cuff (), and a holding member () which holds the inner cuff () and outer cuff (), and the holding member has a 'U' shape. The end portions of the holding member () where the inner cuff () and outer cuff () are arranged are almost parallel to each other, and the inner cuff () and outer cuff () oppose each other. An auxiliary member () which comes in contact with a predetermined position of the ear of a person to be measured and increases the attachment stability of the inner cuff () and outer cuff () at the tragus is attached to the holding member ().
