2. Description of the Related Art Biometric sensors placed on the human body have been used to sense or measure human biosignals.
Such biosensors require flexible substrates or the like to transmit signals, and so proposals have been made to ensure sufficient flexibility to ensure a comfortable feel for the user.
Specifically, a biosensor device has been proposed that includes a non-stretchable portion where a biosensor is arranged, and a stretchable strip or the like (for example, Patent Document 1).
Furthermore, in order to fix such biosensors to the human body, a stick-on biosensor device has been proposed that includes an adhesive layer and a release sheet, and the release sheet is peeled off when in use to expose the adhesive layer (for example, Patent Document 2).

JP 2017-113088 A US Patent Application Publication No. 2019/0150739

However, when placing multiple different types of biosensors on the human body at the same time, it is necessary to place each of the different types of biosensors in a different, appropriate position. However, because the physique of each human body varies depending on the user, it is difficult to place each of these multiple biosensors in an appropriate position without placing unnecessary strain on the human body.

The present invention therefore aims to provide a vital sign monitoring device, vital sign monitoring system, and adhesive vital sign monitoring device that can easily position multiple different types of vital signs sensors in different appropriate positions, even if the physique of each user varies.

In present invention (1), the above object is achieved by a vital sign monitoring device comprising: a main body unit including a first vital sign acquisition unit that acquires vital signs and a control unit that controls the vital sign acquired by the first vital sign acquisition unit; and a mobile unit including a second vital sign acquisition unit that acquires the vital sign; an intermediate unit is disposed between the main body unit and the mobile unit; the main body unit and the mobile unit are connected to the intermediate unit by a first connection unit and a second connection unit, both of which are adjustable in length, so as to be able to communicate with the intermediate unit; and the length directions adjusted by the first connection unit and the second connection unit are each adjustable in different directions.

With this configuration, the first biometric information acquisition unit provided on the main unit and the second biometric information acquisition unit provided on the mobile unit are positioned at different locations on the human body, but the main unit and the mobile unit are both connected to the intermediate unit via length-adjustable first and second connection units so that they can communicate with each other, and the length directions adjusted by the first and second connection units can be adjusted in different directions, so that even users with different physiques can easily position the first and second biometric information acquisition units in appropriate positions.

(2) The vital signs monitoring device of (1) above is preferably characterized in that the intermediate section has a guide shape for arranging the length direction adjusted by the first connection section and the length direction adjusted by the second connection section in different directions, the first connection section and the second connection section are stretchable, and the main section, the intermediate section, and the moving section each have an adhesive layer.

With this configuration, the guide shape of the intermediate section allows the length direction adjusted by the first connection section and the length direction adjusted by the second connection section to be positioned in different directions. The first and second connection sections are stretchable, and the main body section, the intermediate section, and the moving section each have an adhesive layer. Therefore, the main body section and the moving section, on which the biometric information acquisition section is located, can be easily positioned in any position depending on the physique and other differences of the user (subject) of the biometric information monitoring device, and these biometric information acquisition sections can be positioned at appropriate measurement locations for the user.

(3) The biological information monitoring device of (1) or (2) above is preferably characterized in that the first biological information acquisition unit has a pulse wave sensor that detects the user's pulse and an electrocardiogram sensor that detects electrical signals from the heart, and the second biological information acquisition unit has a heart sound sensor that detects vibrations from the heart.

This configuration makes it possible to accurately grasp intracardiac pressure, which can be used to detect signs of worsening heart failure.

(4) In the vital sign monitoring device described in any of (1) to (3) above, the main body unit preferably acquires the vital sign of the second vital sign acquisition unit via the second connection unit, the intermediate unit, and the first vital sign acquisition unit, and transmits the vital sign together with the vital sign of the first vital sign acquisition unit at the same time to another device.

With this configuration, all vital signs can be acquired by the main unit and simultaneously transmitted to another device, such as a management server. This allows data to be synchronized to accurately determine intracardiac pressure, etc., and to accurately grasp signs of heart failure, etc.

(5) The biological information monitoring device described in any of (1) to (4) above is preferably characterized in that the main body unit includes a notification unit that notifies whether the first biological information acquisition unit and the second biological information acquisition unit are each acquiring the biological information.

According to the above configuration, the first biometric information acquisition unit and the second biometric information acquisition unit each include a notification unit (indicator, etc.) that notifies the user whether or not biometric information is being acquired. By visually checking the notification unit, the user can accurately determine whether or not the first biometric information acquisition unit and the second biometric information acquisition unit each are acquiring biometric information.

In present invention (6), the above object is achieved by a vital sign monitoring system comprising a management device for managing vital sign information and a vital sign monitoring device for monitoring the vital sign information, wherein the vital sign monitoring device comprises a main body unit comprising a first vital sign acquisition unit for acquiring vital sign information and a control unit for controlling the vital sign information acquired by the first vital sign acquisition unit, and a mobile unit comprising a second vital sign acquisition unit for acquiring the vital sign information, wherein an intermediate unit is disposed between the main body unit and the mobile unit, and the main body unit and the mobile unit are connected to the intermediate unit by first and second connection units, each of which is adjustable in length, so as to be able to communicate with the intermediate unit, and the length directions adjusted by the first and second connection units are each adjustable in different directions.

In present invention (7), the above object is achieved by a stick-on vital sign monitoring device comprising: a first adhesive portion for fixing a main body portion having a first vital sign acquisition unit that acquires vital sign; a second adhesive portion for fixing a mobile portion having a second vital sign acquisition unit that acquires the vital sign; a connecting portion that electrically connects the main body portion and the mobile portion and is configured to be stretchable; and a release portion that is arranged relative to the main body portion, the mobile portion, and the connecting portion, wherein the release portion comprises a first release sheet that covers the main body portion, a second release sheet that covers the mobile portion, and a third release sheet that covers the connecting portion, and the third release sheet is held in a releasable state by the first adhesive portion and the second adhesive portion.

According to the above configuration, the third release sheet covers the connection portion having an expandable structure and is held in a releasable state by the first adhesive portion and the second adhesive portion.
Therefore, before the third release sheet is peeled off, the third release sheet can prevent the connection portion from stretching, and users can avoid the connection portion from stretching before wearing the adhesive-type vital sign monitoring device, making it difficult to handle.
Therefore, even if the physique of the human body of the user or the like is different, the plurality of biosensors can be easily arranged in different appropriate positions.

(8) The adhesive-type vital sign monitoring device of (7) above is preferably characterized in that the first vital sign acquisition unit has a pulse wave sensor that detects the user's pulse and an electrocardiogram sensor that detects the heart's electrical signals, the second vital sign acquisition unit has a heart sound sensor that detects vibrations from the heart, the first adhesive portion of the main body unit is not formed in a portion of the main body unit where the pulse wave sensor is located and functions, and the second adhesive portion of the moving unit is not formed in a portion of the moving unit where the heart sound sensor is located and functions.

This configuration makes it possible to accurately measure intracardiac pressure, which is used to detect signs of heart failure, without interfering with the operation of the pulse wave sensor and heart sound sensor.

(9) In the adhesive-type vital sign monitoring device of (7) or (8) above, the first release sheet preferably has a fixing portion that abuts and is fixed to the first adhesive portion, and a free end portion that extends from the fixing portion and is not directly fixed to the first adhesive portion.

With this configuration, the user can easily and reliably peel the first release sheet from the first adhesive portion by grasping and operating the free end, thereby fixing the main body to the appropriate measurement site.

(10) In the adhesive-type vital sign monitoring device described in any of (7) to (9) above, the second release sheet preferably has a fixing portion that abuts and is fixed to the second adhesive portion, and a free end portion that extends from the fixing portion and is not directly fixed to the second adhesive portion.

With this configuration, the user can easily and reliably peel the second release sheet from the second adhesive portion by grasping and operating the free end, thereby fixing the moving portion to the appropriate measurement site.

(11) The adhesive-type vital sign monitoring device described in any of (7) to (9) above is preferably characterized in that the first release sheet is not positioned in the portion of the main body where the pulse wave sensor is positioned and functions, and is divided into multiple pieces.

According to the above configuration, the first peel-off sheet is not placed in the part of the main body where the pulse wave sensor is located and functions, so that the user can peel off the first peel-off sheet without adversely affecting the pulse wave sensor.
Furthermore, according to the above configuration, since the first release sheet is divided into a plurality of pieces, the user can fix the main body to the measurement site with higher accuracy.

(12) The adhesive-type vital sign monitoring device described in any of (7) to (10) above is preferably characterized in that the second release sheet is not positioned in the portion of the moving part where the heart sound sensor is positioned and functions, and is divided into multiple pieces.

According to the above configuration, the second peel-off sheet is not placed in the part of the moving part where the heart sound sensor is located and functions, so that the user can peel off the second peel-off sheet without adversely affecting the heart sound sensor.
Furthermore, according to the above configuration, since the second release sheet is divided into a plurality of pieces, the user can fix the moving part to the measurement site with higher accuracy.

(13) The adhesive-type vital sign monitoring device described in any of (7) to (12) above is preferably characterized in that the connection portion is stretchable when the third release sheet is not covering the connection portion.

Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
The embodiments described below are preferred examples of the present invention, and therefore various technically preferable limitations are applied. However, the scope of the present invention is not limited to these embodiments unless otherwise specified in the following description to the effect that the present invention is specifically limited.

(Main configuration of sensor device system 1)
FIG. 1 is a schematic diagram showing the main configuration of a sensor device system 1, which is an example of a biological information monitoring system according to the present invention.
As shown in FIG. 1, the system 1 includes a sensor device 10, which is an example of a biological information monitoring device or a wearable biological information monitoring device, and a management server 800, which is an example of a management device or other device.
The management server 800 has a configuration for estimating intracardiac pressure, the details of which will be described later.

(Main components of the sensor device)
On the other hand, the sensor device 10 is a device for non-invasively acquiring biometric information such as heart sounds, electrocardiograms, and pulse waves to estimate, for example, an increase in intracardiac pressure, which is a sign of worsening heart failure, and as shown in Figure 1, has a main body portion 100, a first connecting portion 200, an intermediate portion 300, a second connecting portion 400, and a moving portion 500.
Each component will be described in detail.

(Main configuration of the main body 100)
The main body 100 has an approximately rectangular shape when viewed from the front, and contains a pulse wave sensor 110, which is an example of the first biometric information acquisition unit, that detects the pulse of the user (subject), and three electrocardiogram sensors 120, 121, and 122, which are also examples of the first biometric information acquisition unit, that detect electrical signals from the heart.
A power button 130 and an indicator 140, which is an example of a notification unit, are arranged on the front surface of the main body 100 (the surface that does not come into contact with the human body).
This indicator 140 indicates whether the pulse wave sensor 110, electrocardiogram sensors 120, 121, 122, heart sound sensor 510 (to be described later), etc. are positioned at appropriate measurement sites, and its specific configuration will be described later.
As will be described later, in addition to the above, the main body 100 also has built-in components within the housing, such as a power supply battery 103, a control circuit (CPU; Central Processing Unit) that controls each element of the main body control unit 101, and a communication unit such as a Bluetooth (registered trademark) element for wireless communication with the management server 800 that serves as the main body control unit 101.

(Main components of pulse wave sensor 110)
The pulse wave sensor 110 (PPG sensor) relating to pulse waves, which is an example of biological information, is, for example, an optical heart rate sensor, and is a device that acquires pulse as biological information.
Specifically, light is emitted from an LED toward the skin, and the light that is reflected by blood vessels and emerges outside the skin is detected.
Oxygenated hemoglobin in the blood has a strong absorption characteristic for light around 550 nm, for example, so the power of the detected 550 nm light varies depending on the amount of blood.
Since blood volume changes with the heartbeat, the pulse wave is detected by observing the change in the power of this light over time, and the pulse rate is measured by observing the period of the change in the power of the light over time.

Furthermore, the measurement site (placement site) of the pulse wave sensor 110 is preferably a site where capillaries are present on the surface of the living body, such as the "subclavian artery" near the collarbone.

(Main configuration of electrocardiogram sensor 120, etc.)
The electrocardiogram sensor 120 (ECG electrodes) relating to an electrocardiogram, which is an example of biological information, is an electrode for an electrocardiogram test, and a plurality of electrodes are placed on the chest or the like.
An electrocardiogram is a test that checks the state of electricity obtained from electrodes to determine whether the heart is beating regularly and whether there is any damage to the myocardium.
In this embodiment, for example, three electrocardiogram sensors 120 (electrodes) are placed around the heart to estimate intracardiac pressure.
However, the number of electrocardiogram sensors 120 etc. (electrodes) is not particularly limited as long as it is at least two or more.

(Main components of indicator 140)
The indicator 140 indicates whether the pulse wave sensor 110, electrocardiogram sensor 120, and heart sound sensor 510 (described later) are positioned at appropriate measurement sites.
Specifically, it is equipped with a pulse wave sensor 110, an electrocardiogram sensor 120, a heart sound sensor 510, and corresponding pulse wave indicators 141, electrocardiogram indicators 142, and heart sound indicators 143, and is configured so that if each sensor is placed in the appropriate position, it is displayed in "green", and if not, it is displayed in "red".
By checking the display of indicator 140, the user can determine whether or not each sensor is placed at an appropriate measurement site.

(Other configurations)
In the present invention, unlike the present embodiment, other display units may be provided on the main body 100. For example, an LED display unit that indicates the communication status or the battery status, an LCD (liquid crystal display) that indicates waveforms, values, etc. may be provided.

(Major configuration of the back side of the main body 100)
FIG. 2 is a schematic diagram showing the configuration of the rear side of the sensor device 10. As shown in FIG.
As shown in Figure 2, the hatched area on the back side (the side that comes into contact with the human body) of the main body 100 of the sensor device 10 has a first adhesive layer 150 (an example of a first adhesive portion) formed thereon for fixing the device to the skin at the measurement site on the human body.
The first adhesive layer 150 is formed of, for example, an acrylic adhesive, a silicone adhesive, a urethane adhesive, a rubber adhesive, or the like.

However, the first adhesive layer 150 is not formed in the area required for sensing by the pulse wave sensor 110 (the area where the pulse wave sensor is placed, where light is emitted from the LED toward the skin and where the light reflected by the blood vessels and exits the skin is detected).
This can prevent the first adhesive layer 150 from interfering with the operation of the pulse wave sensor 110 .

(Main configuration of intermediate section 300)
The intermediate section 300 is an approximately curved rectangle (an example of a guide shape) when viewed from the front, and the first connection section 200 and the second connection section 400 connected to both ends thereof are arranged in different directions (orientations).
In other words, the intermediate portion 300 has a first side 301 connected to the first connecting portion 200 and a second side 302 connected to the second connecting portion 400, and the first side and the second side are non-parallel.
The intermediate unit 300 is configured to be able to communicate with the first connection unit 200 and the second connection unit 400 .
With this configuration, heart sound data acquired by the heart sound sensor 510 possessed by the mobile unit 500 described later can be transmitted to the main unit 100 via the second connection unit 400, the intermediate unit 300, and the first connection unit 200.

As shown in FIG. 2, a third adhesive layer 310 is formed on the back surface of the intermediate portion 300 to fix it to the skin of the human body.
The third adhesive layer 310 is also formed of an acrylic adhesive, a silicone adhesive, a urethane adhesive, a rubber adhesive, or the like.
The third adhesive layer 310 does not necessarily have to be formed on the back surface of the intermediate portion 300 .
Furthermore, no sensors or the like are disposed in the intermediate section 300 .

(Main configuration of the moving unit 500)
The moving unit 500 has a generally circular shape overall, and includes a heart sound sensor 510, which is an example of a second biological information acquisition unit, inside the moving unit 500.
As an example of biometric information, the heart sound sensor (HS sensor) 510, which is related to heart sounds and is a different type of biometric information from the biometric information acquired by the pulse wave sensor 110, electrocardiogram sensor 120, etc. provided in the main body 100, is a sensor that acquires vibrations from the heart, such as the sound made when the heart valves close (heart valve sound), and checks whether the heart valves are malfunctioning or have stenosis, etc.

The measurement site for the heart sound sensor 510 is preferably the sternum, and in particular the lower part of the sternum (the second to fifth ribs, sternum, etc.) to estimate intracardiac pressure.

As shown in FIG. 2, a second adhesive layer 520 (an example of a second adhesive portion) is formed on the rear surface of the moving portion 500 to fix it to the skin of the measurement site on the human body.
The second adhesive layer 520 is formed of, for example, an acrylic adhesive, a silicone adhesive, a urethane adhesive, a rubber adhesive, or the like.
However, the second adhesive layer 520 is not formed in the area necessary for sensing by the heart sound sensor 510 (the area where the heart sound sensor 510 is placed and acquires vibrations from the heart) (an example of the area where the sensor is placed and functions).
This can prevent the second adhesive layer 520 from interfering with the operation of the heart sound sensor 510.

(Main configuration of first connection portion 200)
The first connecting portion 200 is arranged to connect the main body portion 100 and the intermediate portion 300, and is wavy as a whole, and has a configuration that is stretchable and adjustable in length (an example of stretchability).
Specifically, it expands and contracts in the direction of the arrow wa in FIG. 1 (the substantially horizontal direction when the human body is viewed from the front).
The first connecting portion 200 is made of resin, and is expandable and contractible by deformation of the wavy portion thereof.

As shown in FIG. 2, no adhesive layer is formed on the back surface of the first connecting portion 200 .
However, an adhesive layer may be formed on the back surface of the first connection portion 200 .
The first connection unit 200 is configured to be able to communicate with the intermediate unit 300 and the main unit 100 that are connected to it.

(Main configuration of second connection part 400)
The second connecting portion 400 is disposed so as to connect the intermediate portion 300 and the moving portion 500, and is configured to be wavy as a whole and stretchable to adjust its length (an example of stretchability).
Specifically, it expands and contracts in the direction of the arrow wb in FIG. 1 (the substantially vertical direction when the human body is viewed from the front).
The second connecting portion 400 is made of resin, similar to the first connecting portion 200, and is expandable and contractible by deformation of its wavy portion.
As shown in FIG. 2, no adhesive layer is formed on the back surface of the second connecting portion 400 .
However, an adhesive layer may be formed on the back surface of the second connection portion 400 .
The second connection unit 400 is configured to be able to communicate with the mobile unit 500 and the intermediate unit 300 connected thereto.

The first connecting portion has a stretching direction wa and a stretching direction wb of the second connecting portion, and the stretching direction wa and the second connecting portion are formed to be different from each other by interposing a curved intermediate portion 300 therebetween.
That is, the length directions of the first connecting part 200 and the second connecting part 400 can be adjusted in different directions.

Furthermore, in order to enable the biometric information of the heart sound sensor 510 of the moving unit 500 to be transmitted to the main unit 100 via the second connecting unit 400, the intermediate unit 300, and the first connecting unit 200, conducting wires such as flexible circuits are provided in the first connecting unit 200, the intermediate unit 300, and the second connecting unit 400.

The management server 800, sensor device 10, etc. shown in Figure 1 have a computer, which has a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), etc. (not shown), which are connected via a bus.

(Main components of management server 800)
FIG. 3 is a schematic block diagram showing the main configuration of the management server 800 of FIG.
As shown in Figure 3, the management server 800 has a server-side control unit 810, which controls a server-side communication unit 820 for communicating with the sensor device 10, etc., a server-side display 830 for displaying various information, a server-side various information input device 840 for inputting various information, an intracardiac pressure estimation unit (program) 850, and a server-side various information storage unit 860, etc.

Of these, the "intracardiac pressure estimation unit 850" acquires simultaneous biological information, such as "electrocardiogram data,""pulse wave data," and "heart sound data," from the main body unit 100, estimates intracardiac pressure based on this data, and stores the estimated data in the server-side various information storage unit 860.
Based on this estimated intracardiac pressure data, a diagnosis of signs of worsening heart failure, etc., can be made.

(Schematic block diagram of sensor device 10)
FIG. 4 is a schematic block diagram of the sensor device 10 of FIG.
As shown in Figure 4, the main body unit 100 has a main body side control unit 101, which is an example of a control unit, and the control unit 101 controls a main body side communication unit 102 for wireless communication with the management server 800, an electrocardiogram sensor 120, a pulse wave sensor 110, an indicator 140, a battery 103, etc., as well as a main body side various information input unit 104 for inputting various information, and a main body side various information storage unit 105 for storing various information.

As shown in FIG. 4, the main body 100 is configured such that biometric information from the heart sound sensor 510 disposed in the moving part 500 is transmitted to the main body 100 via the second connecting part 400, the intermediate part 300, and the first connecting part 200.
Therefore, the main body 100 is configured to be able to manage biological information from the pulse wave sensor 110, the electrocardiogram sensor 120, etc., and the heart sound sensor 510 at the same time.

(Main configuration of peeling unit 1000)
FIG. 5 is a schematic diagram showing the relationship between the sensor device 10 of FIG. 1 and the peeling unit 1000, and FIG. 6 is a schematic diagram seen from the back side to show the peeling unit 1000.
As shown in Figure 2, a "first adhesive layer 150", a "third adhesive layer 310", and a "second adhesive layer 520" are formed on the back side of the main body part 100, the intermediate part 300, and the moving part 500 of the sensor device 10, respectively.

The first adhesive layer 150, etc. are formed to attach and fix the main body 100, etc. to the measurement site on the biological surface (skin) of the user (subject), but prior to fixing, a "peeling portion 1000" is arranged to cover the first adhesive layer 150, etc. for ease of handling.

Specifically, as shown in Figures 5 and 6, the peeling portion 1000 has a "first peeling sheet 1100" that covers the portion of the first adhesive layer 150 that is not covered by the third peeling sheet 1200, a "third peeling sheet 1200" that covers part of the first adhesive layer 150, the third adhesive layer 310, the first connecting portion 200, the second connecting portion 400 and part of the second adhesive layer 520, and a "second peeling sheet 1300" that covers the portion of the second adhesive layer 520 that is not covered by the third peeling sheet 1200.
Here, the intermediate portion 300, the first connecting portion 200, and the second connecting portion 400 are examples of connecting portions.

(Main configuration of first release sheet 1100)
As shown in FIGS. 5 and 6, the first release sheet 1110 has two release sheets, a first-first release sheet 1110 and a first-second release sheet 1120 .
Furthermore, in order not to impede the operation of the pulse wave sensor 110 of the main body 100, the area corresponding to the portion where the first adhesive layer 150 is not formed is configured so as not to form a release sheet.

As shown in Figures 5 and 6, the first-first release sheet 1110 and the first-second release sheet 1120 of the first release sheet 1100 are arranged adjacent to each other and have the same configuration, so the structure will be explained below using the first-first release sheet 1110 as an example.

FIG. 7 is a schematic explanatory diagram showing the structure of the first release sheet 1100.
As shown in FIGS. 5 and 7, the first-first release sheet 1110 is folded in half and has a fold that forms a substantially V-shaped cross section.
Of the folded portion, the portion that abuts against the first adhesive layer 150 becomes the fixed portion 1111, and the portion that extends from this fixed portion 1111 and is not directly fixed to the first adhesive layer 150 becomes the free end portion 1112 that is not directly fixed to the first adhesive layer 150.

Therefore, by grasping the free end 1112 (label R2, described below) and manipulating it, the user can easily peel it off and gradually expose a portion (half in this embodiment) of the first adhesive layer 150, allowing the main body 100 to be precisely fixed to the measurement location on the human body.

Furthermore, in this embodiment, the first adhesive layer 150 is divided into two parts, and after, for example, the first-1 release sheet 1110 is peeled off and a portion of the first adhesive layer 150 (half of it in this embodiment) is fixed to the human body, the first-2 release sheet 1120 is gradually peeled off, thereby enabling the main body 100 to be fixed to the measurement site more accurately and precisely.

Furthermore, as shown in Figures 5 and 6, the first-first release sheet 1110 and the first-second release sheet 1120 of the first release sheet 1100 each have labels R2 and R3 that act as holding pieces, so the user can more easily peel off the first release sheet 1100 by holding these labels R2 and R3.

Furthermore, labels R2 and R3 are marked with numbers (2, 3, etc.), so by peeling them off in order of decreasing number, the main body 100 can be fixed to the measurement site with greater precision.

(Main configuration of second release sheet 1300)
As shown in Figures 5 and 6, the second release sheet 1300 is arranged to cover the second adhesive layer 520, but in areas corresponding to the portions where the second adhesive layer 520 is not formed so as not to interfere with the operation of the heart sound sensor 510 of the moving part 500, openings are provided so that no release sheet is formed.

By configuring it in this manner, the second release sheet 1300 can be formed without adversely affecting the heart sound sensor 510.
The second release sheet 1300 may be divided into multiple pieces.
With this configuration, the user (subject) can attach and fix the moving part 500 to the measurement site with higher accuracy.

Furthermore, the second release sheet 1300 has a label R5 that serves as a holding piece, so that the user can hold onto this label R5 to more easily peel off the second release sheet 1300.
Furthermore, the label R5 has the number 5 attached thereto, so by peeling off the labels in ascending order of numbers, the moving part 500 can be fixed to the measurement site with greater accuracy.

The second release sheet 1300 may be made up of two release sheets, similar to the first release sheet 1100 in the embodiment.
In this case, the two release sheets that make up the second release sheet 1300 are folded in half, with a fold that forms an approximately V-shaped cross section, and the part of the folded part that abuts the second adhesive layer 520 becomes the fixed part, and the part that extends from this fixed part and is not directly fixed to the second adhesive layer 520 becomes the free end that is not directly fixed to the second adhesive layer 520.

(Main configuration of third release sheet 1200)
5 and 6, the third release sheet 1200 is configured to cover the third adhesive layer 310, the first connecting portion 200, and the second connecting portion 400. In other words, it is configured to cover the connecting portions.
One end of the third release sheet 1200 is disposed adjacent to the first release sheet 1100 and is fixed and held in place by the first adhesive layer 150 .
On the other hand, the other end of third release sheet 1200 is disposed adjacent to second release sheet 1300 and is fixed and held in place by second adhesive layer 520 .

Furthermore, the central portion of the third release sheet 1200 is configured to be fixed and held by the third adhesive layer 310 of the intermediate portion 300 .
The first connecting portion 200 and the second connecting portion 400 covered by the third release sheet 1200 do not have an adhesive layer, and the first connecting portion 200 and the second connecting portion 400 are configured to be easily stretchable.
Therefore, if the third release sheet 1200 is not positioned, when the user holds the sensor device 10, the first connection part 200 and the second connection part 400 will stretch due to gravitational force, making it difficult for the user to accurately position a biosensor such as the heart sound sensor 510 at the measurement position.

In this regard, in this embodiment, if the third release sheet 1200 is placed, the third release sheet 1200 is fixed by the first adhesive layer 150 of the main body portion 100 and the second adhesive layer 310 of the intermediate portion 300, and is configured to prevent the first connection portion 200 placed therebetween from being stretched by gravitational forces, etc.

In addition, the third release sheet 1200 is fixed by the second adhesive layer 520 of the moving part 500 and the third adhesive layer 310 of the intermediate part 300, and is configured to prevent the second connection part 400 arranged therebetween from being stretched by gravitational forces, etc.
On the other hand, when the third release sheet 1200 does not cover the first connecting portion 200 and the second connecting portion 400, the first connecting portion 200 and the second connecting portion 400 are stretchable.
Therefore, the user can easily place each biosensor 110 of the sensor device 10 at the optimum measurement site with high accuracy.

(Example of operation of sensor device system 1)
8 to 10 are schematic explanatory diagrams showing an example of the operation of the sensor device system 1 according to this embodiment.
The sensor device 10 of this embodiment is intended to non-invasively monitor "intracardiac pressure" in order to detect "increased left atrial/left cardiac pressure" particularly during the progression of "heart failure," and is intended for use, for example, in a hospital.
The sensor device 10 may be used not only in a hospital but also in the subject's home, a day care facility, or the like.

To monitor such intracardiac pressure, a pulse wave sensor 110, an electrocardiogram sensor 120, a heart sound sensor 510, etc. are attached to the patient user (subject) to acquire biometric information. As mentioned above, the pulse wave sensor 110 is preferably placed at the "subclavian artery" location, and the electrocardiogram sensor 120, etc. are preferably placed at three locations around the heart.
Furthermore, the heart sound sensor is preferably located "below the sternum."

Among these sensors, the pulse wave sensor 110 and electrocardiogram sensor 120 have measurement sites close to each other, making them easy to position, but the heart sound sensor 510 is located far away from these.

On the other hand, in order to monitor intracardiac pressure, it is necessary to simultaneously acquire these three pieces of biological information, and a sensor device that integrates these three sensors is required.
However, depending on the physical constitution of the patient, the placement intervals of these three sensors may vary greatly, and it is not easy to place each sensor at an appropriate measurement position.
Therefore, in this embodiment, the sensor device 10 is configured to treat these three sensors as a single unit and to allow each to be easily placed in an appropriate position regardless of differences in physique, etc., between patients, etc.

An example of how the sensor device system 1 is used will be specifically described below with reference to FIGS. 8 to 10. FIG.
First, a user uses the sensor device 10 to which the peeling part 1000 is attached, and activates the sensor device 10 by operating the power button 130 on the main body part 100 .

Next, as shown in FIG. 8, the pulse wave sensor 110 of the main body 100 is placed on the "subclavian artery," and the positions of the plurality of electrocardiogram sensors 120 and the like are adjusted so that they are placed around the heart.
At this time, indicator 140 will glow "green" if the placement of each sensor is appropriate, and will glow "red" if it is not appropriate, so the user searches for a position where the indicators for the pulse wave sensor and electrocardiogram sensor are "green."

When these indicators 140 turn “green,” the user operates the label R 2 of the first-first release sheet 1110 to move the free end 1112 .
Then, as shown in Figures 7(A) to (D), the first-1st release sheet 1110 is gradually peeled off from the first adhesive layer 150, and a portion of the first adhesive layer 150 (half in this embodiment) is fixed to the user's skin.
Now that the main body 100 has been temporarily fixed, the user operates the label R3 to prevent it from shifting position, and peels the first-2 release sheet 1120 from the first adhesive layer 150 in the same manner as the first-1 release sheet 1110, fixing the entire first adhesive layer 150 to the skin and confirming the position of the main body 100.

Next, the process proceeds to positioning the heart sound sensor 510 of the moving part 500 in an optimal position.
The preferred location of the heart sound sensor 510 is generally below the sternum (on the sternum at the level of the second rib), for example, in FIG. 8, at the center (NC) of the line connecting the user's nipples.

The user then grasps the label R4 in FIGS. 5 and 6 and removes the third release sheet 1200.
Then, the first connecting part 200 becomes free to expand and contract, and the user moves the intermediate part 300 in the direction of the sternum (in the direction of the arrow h1) in FIG.

At this time, the first connecting portion 200 extends in the horizontal direction in FIG. 9 (the direction of the arrow h1, approximately horizontal when the human body is viewed from the front), so that the intermediate portion 30 can be easily moved.
Then, when the intermediate portion 300 reaches the center of the sternum, the third adhesive layer 310 of the intermediate portion 300 is brought into contact with the skin, thereby fixing the position of the intermediate portion 300.

At this time, since the intermediate portion 300 has a curved shape, the second connecting portion 400 is arranged in the vertical direction in the figure (approximately vertical when the human body is viewed from the front), and the moving portion 500 is located at its tip.
Therefore, as shown in Figure 10, the user extends the second connection part 400 in the vertical direction of Figure 10 (approximately the vertical direction when the human body is viewed from the front) and extends the second connection part 400 so that the heart sound sensor 510 of the moving part 500 is positioned at the measurement site (NC).

Then, when the heart sound sensor 510 is positioned at the measurement site (NC), the label R5 is operated, the second release sheet 1300 is peeled off from the second adhesive layer 520, and the second adhesive layer 520 is brought into contact with the skin, thereby fixing the position of the moving part 500.
At this time, it is confirmed that the indicator 143 of the heart sound sensor of the main body 100 has turned "green."

As described above, the pulse wave sensor 110, electrocardiogram sensor 120, and heart sound sensor 510 can be easily and quickly positioned in appropriate positions regardless of differences in the physique of the user (subject).
Thereafter, the heart sound sensor 510 transmits the biometric information to the main body 100 via the second connection unit 400, the intermediate unit 300, and the first connection unit 200, and transmits it to the management server 800 together with biometric information from the pulse wave sensor 110, the electrocardiogram sensor 120, etc. at the same time.

In the management server 800, the intracardiac pressure estimation unit 850 in FIG. 3 operates to estimate the intracardiac pressure, generate reference information such as signs of worsening heart failure, display it on the server-side display 830, etc., and notify the person in charge.
Therefore, according to this embodiment, by using the non-invasive sensor device 10, it is possible to accurately monitor signs of worsening heart failure, etc.

(Modification of the embodiment)
FIG. 11 is a schematic diagram showing a sensor device 10a according to a modification of this embodiment.
This modified example has a configuration that is almost the same as the above-described embodiment, so a description of the common configuration will be omitted and the following description will focus on the differences.

In this modified example, the two electrocardiogram sensors 120, 122 of the above-described embodiment are arranged on the second moving unit 100c and the third moving unit 100d, and these second moving unit 100c and third moving unit 100d are connected to the main body unit 100 so as to be able to communicate with each other via the fourth connecting unit 100a and the fifth connecting unit 100b, which are wavy and stretchable as a whole.

The second moving unit 100c and the third moving unit 100d are generally circular in shape and have electrocardiogram sensors 120 and 122 therein, which are examples of a first biological information acquisition unit.
The second moving part 100c and the third moving part 100d each have an adhesive layer formed on their rear surfaces for fixing to the skin of the measurement site on the human body.
Furthermore, no adhesive layer is formed on the back surface of the fourth connecting portion 100a and the fifth connecting portion 100b.
However, an adhesive layer may be formed on the back surface of the fourth connecting portion 100a and the fifth connecting portion 100b.
The second moving portion 100c and the fourth connecting portion 100a are covered with a release sheet that is fixed and held by the adhesive layer of the second moving portion 100c and the first adhesive layer 150.
The third moving portion 100d and the fifth connecting portion 100b are covered with a release sheet that is fixed and held by the adhesive layer of the third moving portion 100d and the first adhesive layer 150.
This makes it possible to prevent the second moving section 100c and the third moving section 100d from being stretched by gravitational forces or the like, just as with the third release sheet, as long as the release sheet is in place.
Therefore, the electrocardiogram sensors 120 and 122 can be arranged in more preferable positions.

The above describes an embodiment of the present invention. However, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the claims. The configurations of the above embodiment can be partially omitted or arbitrarily combined in a different manner than described above.
