Description

  The present invention relates to a biosensor device including an electrocardiographic electrode and an acceleration sensor to be worn on the body, and more specifically, measures an electrocardiographic signal and a signal of the posture and motion state of a subject for a long time. It is related with the biosensor apparatus for this.

  According to a 1998 survey by the Ministry of Health, Labor and Welfare, one out of every five Japanese adults has some sleep disorder. In addition, it has been reported that sleep disorder is not only one of the symptoms seen in many depressed patients, but the probability that insomnia patients will develop depression is about 40 times higher. Furthermore, it has been pointed out that the risk of suicide increases due to the combination of depression and sleep disorders. Under such circumstances, in recent years, the importance of measuring a patient's sleep state is increasing not only from the standpoint of treating sleep disorders, but also from the viewpoint of preventing depression.

  As a method for measuring a sleep state, it is possible to measure a sleep state by measuring data such as an electroencephalogram, an eye movement, an electromyogram, and analyzing the data. In addition to data such as brain waves, eye movements, and electromyograms, it is also known to determine a sleep state from information such as body temperature, electrocardiogram signals, blood pressure, breathing, sweating, and body movement. In particular, sleep disorders associated with physical diseases are known to be related to posture and body movements during sleep (such as turning over, trembling, and convulsions), and it is also important to measure them.

  When measuring the sleep state accurately (accurately), you must go to a hospital or other laboratory and stay at least one night there. The number of people is not so large, so it is necessary to go from a distance, sleep overnight in a different environment, and it is difficult to be examined due to the physical and mental burdens. Most of the tests were performed after the disorder was diagnosed.

Therefore, like the electrocardiogram signal guiding electrode device disclosed in Patent Document 1, in order to measure an electrocardiogram signal, a C-shaped base sheet attached to the chest of the body has five electrocardiogram electrodes, 1 It has one acceleration sensor, one piezoelectric sensor, and one temperature sensor, and is configured to send output signals from each electrode and sensor to an analysis / processing device provided outside. By attaching it to the subject, the momentum and calorie consumption are measured based not only on the subject's electrocardiogram signal but also on the output signal from the acceleration sensor, and on the subject's pulse and breath based on the output signal from the piezoelectric sensor The body temperature of the subject can be measured based on the output signal from the temperature sensor (see, for example, Patent Document 1).
JP 2001-269322 A

However, the electrocardiogram signal guiding electrode device described in Patent Document 1 is mainly intended to measure an electrocardiogram signal (electrocardiogram signal) as described in paragraph [0001], By attaching the electrode device for electrocardiogram signal guidance to the body, it is possible to measure an electrocardiogram signal for 24 hours (resting (sleeping or resting) or active (walking or exercising)). However, since it has only one acceleration sensor, it can only measure a very rough state such as a stationary state, a running state, a slow walking state, etc. It was very difficult to measure small body movements such as turning over, trembling, convulsions and sleeping posture. Even if the measurement interval of data is extremely shortened to measure the body movement and posture during sleep and the measurement accuracy is improved, it is not sufficient to detect small body movement and the output signal The amount of data was also very large.
Furthermore, when the posture is measured with one acceleration sensor as in the invention described in Patent Document 1, there are the following problems. For example, in addition to the surface of the body being a curved surface, individual differences in body shape (with epidermis and flesh) are also large, and it has been difficult to measure an accurate posture by measuring at one point. In other words, the output signal from the acceleration sensor worn by a fat person and the output signal from the acceleration sensor worn by a standard figure person or a lean person are signals with greatly different contents even if they are in the same posture. It was. For example, even if a fat person is sleeping in the supine position, the acceleration sensor may be positioned downward due to sagging of the epidermis, and the prone position may be measured instead of the supine position. Even if only the acceleration sensor portion is provided on the waist belt, it is difficult to eliminate the influence of flesh.
That is, in the electrode device for electrocardiogram signal guidance described in Patent Document 1, it is possible to measure not only the electrocardiogram signal but also whether it is in a resting state or an active state, but such as turning over, sleeping, convulsions, etc. during sleep It was very difficult to measure body movement and posture during sleep.

  The present invention has been made in view of the above problems, and an object thereof is to provide a biosensor device that can measure not only an electrocardiogram signal but also a small body motion of a subject.

In order to solve the above-described problems, a biosensor device according to the present invention includes an electrocardiogram electrode that measures an electrocardiogram signal and a three-axis acceleration sensor that measures the movement of the body in a seal portion for attaching to the body. Recording medium for recording output signals from electrocardiographic electrodes and three-axis acceleration sensors of each sealing portion by connecting a plurality of sealing portions through a connecting member and connecting them to a plurality of locations on the body And a recording means for recording on the recording medium are provided at a specific location or outside of the seal portion or the connecting portion, and the recording means, the electrocardiographic electrode and the triaxial acceleration sensor are connected by radio or cable. Is.
Therefore, an electrocardiogram electrode and a triaxial acceleration sensor are provided in a seal portion, and a plurality of seal portions are attached to the body, and output signals from the electrocardiogram electrode and the triaxial acceleration sensor are recorded on a recording medium. Therefore, it is possible to measure not only the electrocardiogram signal but also the movement and state of the part to which the seal portion is attached, and the posture and body movement (small body movement) data during sleep or activity can be obtained. .

  The plurality of seal portions may be connected on substantially the same plane by a connecting portion.

The connecting portion may be substantially T-shaped or substantially Y-shaped, and each of the seal portions may be provided at three ends of the connecting portion.

A holder portion provided with the recording means and the recording medium may be provided on the opposite surface of the surface of one seal portion that contacts the body.
In addition, a holder provided with the recording means and the recording medium may be attached to the body with a belt member.

  A belt member that is mounted on the body opposite to the surface of one seal portion that contacts the body, or a holder portion that includes transmission means that wirelessly transmits signals output from the electrocardiographic electrode and the triaxial acceleration sensor. The external recording unit may include a receiving unit that receives a signal transmitted from the transmitting unit, the recording unit, and the recording medium.

In the biosensor device according to the present invention as described above, a plurality of seal portions each including an electrocardiogram electrode and a three-axis acceleration sensor are connected and integrated by a connecting portion. Not only can posture be measured, but also small body movements and electrocardiogram signals during sleep can be measured, and data used in diagnosing sleep disorders can be measured.
In addition, since the seal portion includes an electrocardiogram electrode and a three-axis acceleration sensor, if the seal portion is peeled off from the body, whether or not the seal portion is peeled off based on an abnormal signal from the electrocardiogram electrode. Since it is clearly understood, an output signal from the three-axis acceleration sensor from the peeled seal portion can be regarded as an error, and erroneous measurement can be prevented.
In addition, since the seals are attached to different locations, it is possible to measure the movement and posture of the body at each attachment position, and not only the presence or absence of exercise, but also various bodies such as back and forth movement, left and right movement, and rotational movement It is possible for the first time to measure movement. Further, the output signal can be corrected based on the output signal from the acceleration sensor of each seal portion and its application position, and the influence of the body shape (skin and flesh) can be reduced, and an accurate posture can be measured.

  Further, since the plurality of seal portions are connected on the same plane by the connecting portion, it is easy to attach to the body (particularly the chest and back), and the feeling of discomfort can be reduced even when wearing for a long time.

  In addition, since the connecting portion is made of a substantially T-shaped, substantially Y-shaped or substantially L-shaped sheet and has three seal portions at the end or corner, the seal portion and the connecting portion are integrated. The body contact portion can be reduced, and the biosensor device can be made less uncomfortable for the subject.

In addition, since the connecting part is composed of a stretchable net member, it can fit the body during sleep and exercise, and can also increase breathability, further reducing the sense of discomfort of the subject Can do.
Furthermore, since the connecting portion has elasticity, the seal portion can be attached to an appropriate position even for subjects having different body shapes. Therefore, a single biosensor device can cope with subjects having various body shapes, so that a low-cost biosensor device can be obtained.

  Moreover, since the bending strength of a seal part can be improved by providing a reinforcement in a seal part, the skin entrainment of a seal part can be suppressed and exact data can be measured.

Moreover, since the temperature sensor is provided, deep body temperature and skin temperature can be measured. And this temperature data can obtain the objective material of sleep start time.
In addition, since an oxysensor is provided, it is possible to know the decrease in oxygen saturation due to apnea by measuring the oxygen saturation of the subject, resulting in an apnea condition in sleep apnea syndrome. It can be used as a material for determining whether or not it is present.
Furthermore, by providing a microphone, it is possible to measure sputum, asthma, cough, heart sounds, and the like. In other words, by measuring sputum, it is possible to obtain a judgment material for initial judgment of obstructive sleep apnea syndrome, and by measuring asthma and cough, a judgment material for sleep disorder caused by breathing can be obtained. It can be used as a judgment material for cardiac function by measuring heart sounds.

  In addition, since one of the seal portions is attached to the body surface of the xiphoid process, when the subject is obese, it is less affected by meat (fat) than when the seal portion is attached to the abdomen. , More accurate posture and body movement can be measured. Moreover, when the temperature sensor is provided in the seal part adhered to the body surface of the sword-shaped projection, the deep body temperature can be measured.

  Moreover, since the sticking auxiliary means is provided in the seal portion, even one person can easily stick to the body.

Further, since the recording means is provided on the surface opposite to the contact surface of the seal portion with the body, the seal portion and the recording means can be integrated.

  Further, since the output signals from the electrocardiogram electrode and the triaxial acceleration sensor are transmitted to the external recording unit by wireless means and recorded, there is no need to consider the size and weight of the recording medium.

An embodiment of the biosensor device according to the present invention will be described below.
For example, as shown in FIG. 1, the biosensor device 1 according to the present invention connects three seal portions 2 (2a, 2b, 2c) on a substantially same plane by a substantially T-shaped connecting portion 3. The seal portion 2c located on the lower body side (lower side) when mounted on the examiner's chest (body) is provided with a base portion 4. The base portion 4 and the seal portions 2a and 2b located on the head side (upper side) are connected by a cable 7 and integrated.

  As shown in FIG. 2, the seal portion 2 includes an electrocardiogram electrode 5 for measuring an electrocardiogram signal and a triaxial acceleration sensor 6 for measuring a body movement and posture, which are attached to the skin S. It is comprised by the patch 8 for making it stick (refer FIG. 3). The seal portion 2 is a cable 7 in which a plurality of signal lines for transmitting output signals from the electrocardiogram electrode 5 and the triaxial acceleration sensor 6 and a power line for supplying electric power to the triaxial acceleration sensor are combined. Is connected. The seal portion 2 has a substantially rectangular shape when viewed from the front, but may have a shape such as a substantially circular shape, a substantially oval shape, or a substantially bowl shape. Further, as shown in FIG. 3 and the like, the seal portion 2 is configured in a plate shape (or a sheet shape) having flexibility, and is substantially the same thickness as the connection portion 3 or thicker than the connection portion 3.

  The biosensor device 1 attaches the three seal portions 2, ..., 2 to the skin of the subject. As shown in Fig. 1, the seal portion 2a is placed on the right chest of the subject. The seal portion 2b is attached to the left chest, and the seal portion 2c is attached so as to be located along the body axis in front view. The seal portion 2a and the seal portion 2b are such that the seal portion 2a and the seal portion 2b are at the same height in a front view, and a body axis (spine) is located at a substantially intermediate position between the two seal portions 2a and 2b. It is stuck so that it is located. And the said seal | sticker part 2c is stuck so that it may be located in the body surface of the xiphoid process of a sternum in front view. In addition, the said seal | sticker parts 2a, 2b, 2c may be affixed on the other body surface.

The electrocardiographic electrode 5 provided in the seal part 2 is composed of a member such as metal, conductive rubber, or conductive fiber, and measures an electrocardiographic signal by contacting the skin S as shown in FIG. It is possible. Note that an electrocardiographic signal may be measured by providing a conductive resin or the like between the skin S and the electrocardiographic electrode 5.
The triaxial acceleration sensor 6 detects acceleration and gravity directions in three orthogonal directions of the left and right direction (x axis), the front and rear direction (y axis), and the vertical direction (z axis) of the body. 2 and 3, the electrocardiographic electrode 5 and the triaxial acceleration sensor 6 are arranged adjacent to each other along the contact surface 8s with the skin S, but they are arranged apart from each other or have a thickness. They may be arranged side by side in the direction.

In this way, by attaching the seal portion 2 including the electrocardiographic electrode 5 and the triaxial acceleration sensor 6 to the body surface of the right chest (near), the left chest (near), and the xiphoid process (near), respectively. The electrocardiogram signals from these three locations can be measured for 24 hours (that is, both during sleep and during activity).
In addition, since the acceleration and gravity direction of each mounting position can be measured from the output signal from the 3-axis acceleration sensor, only the presence or absence of movement (whether it is stationary or moving) In addition, small body movements such as turning over, and types and postures of body movements can also be measured. In addition, since the output signals can be corrected based on the output signals from the plurality of acceleration sensors and their application positions, the influence of the body shape (skin and flesh) can be eliminated and an accurate posture can be measured.
In particular, the seal portion 2c is affixed to the surface of the xiphoid body in front view, and the seal portions 2a and 2b are affixed to both the left and right chests at substantially the same distance from the body axis. It is possible to clearly measure body motion such as motion, left-right motion, and rotational motion (rotational motion around the body axis). Furthermore, since the seal portion 2c is attached to the body surface of the xiphoid process, when the subject is obese, it is less affected by meat (fat) than when the seal portion 2c is attached to the abdomen, More accurate posture and body movement can be measured.
Further, when the seal portion 2 is peeled off from the skin S, the output signal from the electrocardiographic electrode provided in the seal portion 2 becomes an abnormal value, and it is clearly determined whether or not the seal portion 2 is stuck to the skin. Since it understands, the output signal from the 3-axis acceleration sensor of the seal | sticker part 2 which peeled can be made into an error, and an erroneous measurement can be prevented.

Further, the contact surface 8s of the patch 8 of the seal portion 2 with the skin S is provided with a sticking property so that an electrocardiogram signal and a body movement can be measured in a state of being attached to the body even during sleep or exercise. ing.
It is preferable that the seal portion 2 (patch 8) is thinner and lighter because it does not give a sense of discomfort (discomfort) to the subject.
However, when the light and thin seal portion 2 (patch 8) is used, the seal portion 2 may be caught by skin. That is, due to skin entrainment, the triaxial acceleration sensor is also involved in the skin, and a normal posture may not be measured.
Therefore, as shown in FIG. 3A, the patch 8 may not be provided with a reinforcing body, but may be made of a material having a high bending strength so that the skin of the patch 8 is prevented. When the bending strength of the patch 8 is low, as shown in FIG. 3 (b), a reinforcing plate 9 having a high bending strength is provided on the surface opposite to the contact surface 8s to increase the bending strength of the seal portion 2. May be. In addition, as shown in FIG. 3C, a plurality of shaft members 10,..., 10 having high bending strength may be provided inside the patch 8 to increase the bending strength of the seal portion 2.

It may be possible to make it easy to understand by one person and easily install it alone.
Also, the order of attachment (for example, the number “1” on the upper surface of the seal portion 2c, the number “2” on the upper surface of the seal portion 2b, and the number “3” on the upper surface of the seal portion 2a) is shown. Not only that, it is also possible to know the mounting direction from the direction of the numbers.

The base portion 4 is provided on the upper surface of the lower-body-side seal portion 2c (the surface opposite to the skin contact surface 8s), and outputs from the electrocardiographic electrode 5 and the triaxial acceleration sensor 6 provided in the seal portion 2c. It is wired so that it can receive signals. The recording medium 13 is preferably a small and lightweight recording medium, and is preferably a recording medium using a semiconductor such as an SD memory card. However, other recording media may be used.
As described above, by providing the base portion 4 on the upper surface of the seal portion 2 and integrating the base portion 4, the uncomfortable feeling of the subject at the time of wearing can be reduced. Therefore, sleep state data close to a state in which the biosensor device 1 is not worn can be measured.
When the base portion 4 is provided on the upper surface of the seal portion 2c and integrated, the base portion 4 may be provided instead of providing the seal portion 2 with the triaxial acceleration sensor 6.

It is preferable that the connecting portion 3 is composed of a sheet-like net member to improve air permeability and prevent the subject from getting rashed. In addition, the connection part 3 may be comprised from the net | network material which has a stretching property, and may reduce a sense of incongruity of a test subject so that it may fit a body also at the time of sleep or exercise.
Further, the connecting portion 3 is provided with a hollow cylindrical portion (not shown) for accommodating the cable 7, and the connecting portion 3 is accommodated by bending (meandering) the cable 7 in the cylindrical portion. The cable 7 connects the seal portion 2 and the base portion 4 even when is extended.
As described above, since the connecting portion 3 has elasticity, the seal portions 2,..., 2 can be attached at appropriate positions even for subjects having different body shapes. Therefore, since one biosensor device 1 can deal with subjects having various body shapes, a low-cost biosensor device can be obtained.
It should be noted that it may be made of a non-stretchable material (substantially no stretch), such as a cloth, and it may be difficult to change the distance between the seal portions 2,.

  The biosensor device 1 includes a temperature sensor (not shown) for measuring body temperature (skin temperature and deep body temperature) other than the electrocardiographic electrode 5 and the triaxial acceleration sensor 6 and measures the oxygen saturation of the subject. Various sensors such as an oxysensor (for example, a reflection type oxysensor) (not shown), a microphone (not shown) for measuring respiratory sounds and heart sounds such as sputum, asthma, and cough may be provided. The temperature sensor, the oxy sensor, the microphone, and the like need only be provided in the biosensor device 1, but may be provided in two or more.

  The temperature sensor can measure the deep body temperature by providing the temperature sensor, in particular, in the seal portion 2c attached to the body surface of the sword-shaped projection. The other seal portions 2a and 2b may be provided with temperature sensors to measure the skin temperature. By providing a temperature sensor, peripheral vasodilation occurs due to the influence of autonomic nerves (sympathetic nerve, balance fluctuation under parasympathetic nerve control) at the start of sleep (sleeping), for example, body surface temperature rises (for example, sleeping sweat) Thus, it can be used as a material for objective judgment of sleep start time.

  In addition, the oxysensor can know a decrease in oxygen saturation due to apnea by measuring the oxygen saturation of the subject, and whether or not an apnea condition occurs in sleep apnea syndrome. It can be used as a basis for judgment.

In addition, the frequency of epilepsy is important for early judgment of sleep disorders, especially obstructive sleep apnea syndrome, and is currently used as an important judgment material for differential diagnosis by requesting observation from family members, etc. . In addition, by measuring respiratory sounds such as asthma and cough, it is used as a judgment material for sleep disorders caused by breathing. Therefore, it is possible to measure these quantitatively by providing a microphone to the biosensor device and measuring respiratory sounds such as wrinkles during sleep, asthma and cough. Further, by measuring heart sounds with a microphone, it can also be used as a judgment material for cardiac function.
The microphone is provided in the seal part 2 and the base part 4, and in particular, the seal part 2 and the base part 4 so that the directivity direction of the microphone is arranged on the body side so that the directivity is enhanced on the body side.
