Problems solved by technology

[0011] However, because the earlobe is soft, relatively large, and highly exposed, it is easy to install a hoop bag, but the tragus is relatively hard, and its shape varies greatly from person to person. Therefore, the earlobe installation device described in Patent Document 1 cannot be used. The structure of the hoop bag is transferred to the tragus intact
That is, even if the structure of the mounting portion described in Patent Document 1 is used, it is difficult to stably obtain the blood pressure measurement result on the tragus portion
In addition, if the installation is carried out reluctantly, there is also an increased risk of injury to the person being measured

Embodiment approach

[0155] In the above-mentioned embodiment, if image 3 As shown, only one of the pair of cuffs having a structure sandwiching the tragus 221 (inside the inner cuff assembly 6 ) has an irradiation unit (LED 20 ) that irradiates light to the blood flow of the blood vessel and detects reflection from the blood flow. Light receiving part (phototransistor 21).

[0156] Figure 11 It is a block diagram of a configuration example of an ear-type sphygmomanometer 1 as a photoplethysmomanometer according to another embodiment. In this figure, the same symbols are used for the structures or components already described, and descriptions are omitted. LEDs 20a and 20b as light emitting parts and phototransistors 21a and 21b as light receiving parts for detecting reflected light are built into the clamping parts. Both the inner cuff bag assembly 6 and the outer cuff bag assembly 7 of the tragus 221 .

[0157] A configuration may be adopted in which sensors are provided on the inner and ou...

Abstract

Provides a blood pressure measurement device that can stably attach a cuff to the tragus where individual differences are large. The mounting part (3) is integrally formed or has a shape part (52) filling the space from the concha to the antihelix, the first protrusion (54) extending from the shape part toward the external auditory canal, and the first protrusion An integral part (50) of a second protruding portion (55) extending from the shape portion approximately orthogonal to the tragus, and an ear frame portion (51) extending from the shape portion, holds the inner cuff in place. The end of the first protrusion, fix the holding member (15) on the end of the second protrusion, and the outer hoop bag (7, 8) is fixed by the width adjustment screw (11) that can adjust the clamping width of the relative tragus. Set on the holding part.

Description

technical field [0001] The present invention relates to a blood pressure measuring device, and in particular relates to a technology using the outer ear and its surrounding parts as the measured parts. Background technique [0002] Blood pressure fluctuates every moment according to changes in the external environment or internal environment. Therefore, it is desirable to be able to record each beat continuously, but even if continuous recording is not possible, it is very important for health management to measure blood pressure changes over time by continuously measuring blood pressure on a regular basis (intermittently) throughout the day. [0003] In the case of regularly measuring blood pressure with a current blood pressure measuring device, for example, the blood pressure is measured by wrapping a cuff around the upper arm of the person to be measured. In this case, a large-sized cuff covering the upper arm and a main body of the blood pressure measuring device conne...
