Blood pressure measuring apparatus
First Claim
1. A blood pressure measuring apparatus characterized by 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 one end of said holding means is open, end portions of said holding means where said inner cuff and said outer cuff are arranged are substantially parallel, and said inner cuff and said outer cuff oppose each other, and an auxiliary member which comes in contact with a predetermined position of an ear of a person to be measured and increases attachment stability of said inner cuff and said outer cuff at the tragus is attached to said holding means.

Abstract
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 (3) of the blood pressure measuring apparatus has an inner cuff (6), an outer cuff (7), and a holding member (10) which holds the inner cuff (6) and outer cuff (7), and the holding member has a “U” shape. The end portions of the holding member (10) where the inner cuff (6) and outer cuff (7) are arranged are almost parallel to each other, and the inner cuff (6) and outer cuff (7) oppose each other. An auxiliary member (80) 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 (6) and outer cuff (7) at the tragus is attached to the holding member (10).
