Description

  The present invention relates to a sphygmomanometer that measures blood pressure in a part of a subject, particularly in the outer ear.

  With the progress of aging, the response to lifestyle-related diseases such as hypertension in adults has become a major social issue. It is recognized that continuous collection of long-term blood pressure data is very important, especially for diseases related to high blood pressure.

  Conventionally, there is a patient monitor device that is inserted into the external auditory canal and is always worn as a device that measures biological information at the external ear (see, for example, Patent Document 1). This can be calculated from the amount of received light of the scattered light of infrared light and visible light that radiates the pulse, pulse wave, electrocardiogram, body temperature, arterial blood oxygen saturation, blood pressure, etc. into the living body.

  Moreover, as an apparatus to be mounted on the ear canal, there is an emergency information apparatus that includes wireless communication means and includes an arterial blood oxygen saturation sensor, a body temperature sensor, an electrocardiogram sensor, and a pulse wave sensor (see, for example, Patent Document 2). ).

On the other hand, with regard to blood pressure measurement, blood pressure measurement devices based on blood vessel pulsation waveforms are in line with other methods such as cuff vibration method and volume compensation method (for example, see Non-Patent Document 1). It is recognized as a method for measuring blood pressure. In the present specification, the names of the outer ears are based on Non-Patent Documents 2 and 3.

The generation of noise due to vibration of the second blood pressure measurement sensor 42 is prevented, and the blood pressure of a plurality of portions or a plurality of portions of the subject are efficiently and continuously maintained without restricting the posture and movement of the subject. The blood pressure of the subject can be measured.

  As described above, the sphygmomanometer of the present invention eliminates the cause of the measurement error caused by the blood pressure measurement operation, and does not restrict the posture and movement of the subject, and can continuously and efficiently perform the measurement. It is possible to provide a sphygmomanometer that measures the blood pressure of a plurality of portions of a specimen or the blood pressure of a plurality of subjects.

  Since the blood pressure measurement device of the present invention can stably measure blood pressure for a long time without restricting the posture and movement of the subject, it can also be used as a means for knowing the physical condition and the activity state of the body. can do.

It is a figure which shows the structure of the blood pressure meter of embodiment of this invention. It is a figure which shows the example of the mounting state to the outer ear of the blood pressure meter of embodiment of this invention. It is a figure which shows the structure of the blood pressure meter of embodiment of this invention. It is a figure which shows the structure of the blood pressure meter of embodiment of this invention.
