Description

adapter

[0001] The present invention relates to a wearable device that measures a subject by attaching sensors such as electrodes to the subject's body.

[0002] The number of patients with heart disease in Japan is increasing year by year, and for early detection, continuous long-term electrocardiogram waveform measurement in daily life is necessary. For this reason, progress is being made in the development of wearable devices that can measure electrocardiogram waveforms not only in hospitals and facilities but also in patients' daily lives at home. For example, Holter electrocardiographs, such as those described in Non-Patent Document 1, are commercially available as such wearable devices.

[0003] Holter ECG monitors are suitable for long-term measurement because they can provide stable measurements even when the wearer moves. However, Holter ECG monitors require wiring and multiple electrodes to be attached in the correct positions, which can be a significant burden on the user when worn and can be uncomfortable to wear. Furthermore, they cost several hundred thousand yen, which poses a cost issue.

[0004] The above problem can be solved by configuring the electrocardiograph as a patch-type electrocardiograph consisting of a terminal and an adapter with electrodes. Figure 7 shows an example of the configuration of a patch-type electrocardiograph. The patch-type electrocardiograph consists of a terminal 50 and an adapter with electrodes 10.

[0005] The terminal 50 is a device that processes biosignals measured by the electrode section and wirelessly transmits them to an external device. The electrode-equipped adapter 10 includes connector sections (20-1, 20-2), electrode sections (30-1, 30-2), wiring sections (40-1, 40-2), a flexible substrate 11, a reinforcing substrate 13, and an adhesive substrate 12 in areas other than the electrode sections that come into contact with the skin.

[0006] The connector sections (20-1, 20-2) of the electrode adapter 10 are paired with the connector sections (60-1, 60-2) of the terminal 50, respectively, and are detachable. Examples of the connector section configuration include snap buttons such as American snaps. In a patch-type electrocardiograph, a reinforcing base material 13 made of a resin with low elasticity is generally inserted between the flexible base material 11 of the electrode adapter 10 and the wiring sections (40-1, 40-2) in order to withstand the load in the crimping process when attaching the snap buttons.

[0007] For the electrode parts (30-1, 30-2) that come into contact with the skin of the living body 1, a commercially available conductive adhesive sheet (conductive gel) or the like is used to reduce costs, and a stretchable and flexible material is used for the wiring parts (40-1, 40-2). The size of the patch-type electrocardiograph is, for example, about several centimeters (<5 cm) for the long part of the terminal 50, and the distance between the electrode parts (30-1) and (30-2) is about 10 cm.

[0008] In a patch-type electrocardiograph, the terminal 50 is reusable and the electrode adapter 10 is a disposable mass-produced product, so costs can be reduced compared to a Holter electrocardiograph. Furthermore, compared to a Holter electrocardiograph, a patch-type electrocardiograph is smaller and easier to wear because it only needs to be attached to a part of the body, making it possible to realize a wearable device with high usability.

[0010] However, in a patch-type electrocardiograph, if reinforcing substrate 13, which has little elasticity, covers the entire surface area of ​​adapter 10, there is a problem of inhibiting the elasticity of flexible substrate 11. For example, as shown in Fig. 7, if the inter-connector distance of terminal 50 is A and the inter-connector distance of adapter 10 is B, a relative error will occur between inter-connector distance A and inter-connector distance B due to manufacturing errors in the connector positions of terminal 50 and adapter 10, making it difficult to attach or detach terminal 50, resulting in a problem of a lower yield of adapter 10 and making it difficult to reduce costs.

[0011] Furthermore, if a reinforcing substrate is attached to the wiring or electrode area, the flexibility of the flexible substrate and wiring is hindered, and the contact impedance between the electrode and the skin fluctuates with the wearer's body movements, which may increase the burden on the wearer in order to perform accurate measurements.

[0012] The present invention aims to provide a wearable device that is low cost and places little strain on the wearer.

[0013] In order to solve the above problems, the adapter of the present invention includes a first electrode section and a second electrode section for contacting a living body, a first connector section and a second connector section for attaching and detaching a terminal that processes and wirelessly transmits a biosignal measured by the first electrode section and the second electrode section, a first wiring section for electrically connecting the first electrode section and the first connector section, a second wiring section for electrically connecting the second electrode section and the second connector section, a flexible base material having stretchability on which the first connector section and the second connector section are arranged, and an adhesive base material for closely adhering the first electrode section and the second electrode section to the living body. and a reinforcing substrate that is arranged in at least a portion between the flexible substrate and the adhesive substrate and has less elasticity than the flexible substrate, wherein the reinforcing substrate is arranged in a first region in which the first connector portion is arranged and which has a predetermined width in the arrangement direction of the first connector portion and the second connector portion, and in a second region in which the second connector portion is arranged and which has a predetermined width in the arrangement direction of the first connector portion and the second connector portion, and the reinforcing substrate is not arranged in at least a portion of a third region between the first region and the second region, or the reinforcing substrate has a pore structure.

[0014] According to the present invention, it is possible to provide a wearable device that is low cost and places little strain on the wearer.

[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. The present invention can be implemented in various embodiments and is not limited to the embodiments described below.

[0017] First Embodiment As described above, in a conventional patch-type electrocardiograph, the reinforcing base 13 is disposed over the entire surface of the electrode adapter 10, and the reinforcing base 13 is sandwiched between the flexible base 11 and the wiring portions (40-1, 40-2). In this configuration, the reinforcing base 13, which has low elasticity, is present between the two connector portions (20-1, 20-2), which may inhibit the elasticity of the flexible base 11 and make it difficult to adjust the distance between the two connector portions (20-1, 20-2).

[0018] 1A and 1B are diagrams showing an example of the configuration of an adapter according to a first embodiment of the present invention. Fig. 1A is a cross-sectional view of the adapter 10 at the position where the connectors (first connector, second connector) (20-1, 20-2) are arranged, and Fig. 1B is a top view of the adapter 10 as seen from the side where the connectors (20-1, 20-2) are arranged. In Fig. 1B, other components such as the flexible substrate 11 are omitted in order to explain the arrangement of the reinforcing substrates (13-1, 13-2).

[0019] The adapter 10 of this embodiment includes electrode sections (first electrode section, second electrode section) (30-1, 30-2) for contacting the living body 1, connector sections (20-1, 20-2) for attaching and detaching a terminal that processes and wirelessly transmits a biological signal measured by the electrode sections (30-1, 30-2), and wiring sections (first wiring section, second wiring section) (40-1, 40-2) for electrically connecting the electrode sections (30-1, 30-2) and the connector sections (20-1, 20-2).

[0020] The adapter 10 of this embodiment has a layered structure consisting of a stretchable flexible substrate 11 on which the connector portions (20-1, 20-2) are arranged, an adhesive substrate 12 for adhering the electrode portions (30-1, 30-2) to the living body 1, and reinforcing substrates (13-1, 13-2) arranged between the flexible substrate 11 and the adhesive substrate 12.

[0021] The reinforcing base materials (13-1, 13-2) are used to reinforce the structure of the adapter 10 to withstand the loads that occur during the crimping process when attaching a connector such as a snap button, as in the conventional case. The reinforcing base materials (13-1, 13-2) are made of a material with low elasticity, such as resin. In the adapter 10 of this embodiment, the positions at which the reinforcing base materials (13-1, 13-2) are arranged differ from those of the conventional configuration.

[0022] The electrode parts (30-1, 30-2) may be commercially available conductive gel electrodes, and the wiring parts (40-1, 40-2) may be made of, but are not limited to, an Ag / AgCl sheet, silver paste, copper foil, or conductive fabric.

[0023] Examples of the connector parts (20-1, 20-2) include, but are not limited to, snap buttons such as American snaps. In addition to snap buttons, magnetic hooks and the like may also be used. The arrangement of the recesses and protrusions in the connector parts is also not limited to that shown in the drawings.

[0024] The flexible substrate 11 may be made of, but is not limited to, silicone rubber, polyethylene, expanded polyethylene, polyimide, PET, PP, etc. The adhesive substrate 12 is a biological adhesive tape that is placed in an area other than the electrode portion that comes into contact with the skin, and is used to adhere the electrode portions (30-1, 30-2) to the living body 1.

[0025] In the adapter 10 of this embodiment, as shown in Figures 1A and 1B, reinforcing base materials (13-1, 13-2) are arranged in regions #1 and #2 (first region, second region) of predetermined width in which the connector portion (20-1) and the connector portion (20-2) are arranged.

[0026] On the other hand, no reinforcing substrate is disposed in region #3 (third region) between the regions where the connector portion (20-1) and the connector portion (20-2) are disposed, and in regions #4 and #5 (fourth region, fifth region) where the electrode portions (30-1, 30-2) and the wiring portions (40-1, 40-2) are disposed.

[0027] <Adjusting the Distance Between Connectors> Figure 2 is a diagram for explaining adjustment of the distance between connectors in the adapter according to the first embodiment of the present invention. As explained in Figure 7, the distance between the connectors of terminal 50 is A, and the distance between the connectors of adapter 10 is B. When A < B, the adapter is extended or contracted in the direction of the arrow shown in Figure 2, and when A > B, the adapter is extended or contracted in the direction of the arrow shown in Figure 2 to adjust the distance between the connectors of adapter 10. This makes it possible to easily attach and detach the terminal and the adapter.

[0028] According to the configuration of the adapter of this embodiment, the reinforcing base materials (13-1, 13-2) in the area where the connector portion (20-1) and the connector portion (20-2) are located function to withstand the load in the crimping process when the connectors are attached or detached, while the distance between the connector portion (20-1) and the connector portion (20-2) is adjustable. As a result, even if a relative error occurs in the distance between the connectors of the terminal 50 and the adapter 10, the error can be absorbed on the adapter 10 side, making it possible to easily attach or detach the terminal 50 and the adapter 10.

[0029] Furthermore, since no reinforcing substrate is disposed in regions #4 and #5 (fourth and fifth regions) where the electrode sections (30-1, 30-2) and wiring sections (40-1, 40-2) are disposed, the reinforcing substrate does not inhibit the flexibility of the flexible substrate or wiring sections. This prevents fluctuations in contact impedance between the electrodes and the skin due to the wearer's body movements, enabling accurate measurements to be performed without increasing the burden on the wearer.

[0030] Second Embodiment Figures 3A to 3E show an example of the configuration of an adapter according to a second embodiment of the present invention. Figure 3A is a cross-sectional view of adapter 10 at the connector arrangement position, and Figures 3B to 3E are top views of adapter 10 as seen from the side where connector portions (20-1, 20-2) are arranged. In Figures 3B to 3E, other components such as flexible substrate 11 are omitted in order to illustrate the arrangement of reinforcing substrates (13-1 to 13-5).

[0031] In the adapter 10 of this embodiment, as shown in Figures 3A to 3E, similarly to the second embodiment, reinforcing substrates (13-1, 13-2) are arranged in regions #1 and #2 (first region, second region) of predetermined width in which the connector portion (20-1) and the connector portion (20-2) are arranged.

[0032] In the adapter 10 of this embodiment, furthermore, reinforcing substrates (13-3 to 13-5) are arranged in region #3 (third region) between the regions where the connector portion (20-1) and the connector portion (20-2) are arranged, and in regions #4 and #5 (fourth region, fifth region) where the electrode portions (30-1, 30-2) and the wiring portions (40-1, 40-2) are arranged.

[0033] In the second embodiment, the reinforcing substrates (13-1 to 13-5) arranged in regions #4 and #5 have a pore structure in which pores are arranged continuously and regularly, and are stretchable in the direction of connector arrangement. Figures 3B to 3E show specific examples of this pore structure. Figure 3B shows a mesh structure, Figure 3C shows a meander structure, Figure 3D shows a slit structure, and Figure 3E shows a dot structure. The shape of the pores in the dot structure of Figure 3E may be either a perfect circle or an ellipse.

[0034] The configuration of the adapter 10 of this embodiment differs from that of the first embodiment in that a reinforcing base material (13-3) is disposed in region #3 (third region) between the regions where the connector portion (20-1) and the connector portion (20-2) are disposed. Because this reinforcing base material (13-3) has a pore structure, the distance between the connector portion (20-1) and the connector portion (20-2) is adjustable.

[0035] In the second embodiment, similar to the first embodiment, the reinforcing base materials (13-1, 13-2) in the region where the connector portion (20-1) and the connector portion (20-2) are arranged function to withstand the load in the crimping process when the connectors are attached or detached, while the distance between the connector portion (20-1) and the connector portion (20-2) is adjustable. As a result, even if a relative error occurs in the distance between the connectors of the terminal 50 and the adapter 10, the error can be absorbed on the adapter 10 side, making it possible to easily attach or detach the terminal 50 and the adapter 10.

[0036] Furthermore, since the reinforcing substrates arranged in regions #4 and #5 (fourth and fifth regions) where the electrode sections (30-1, 30-2) and wiring sections (40-1, 40-2) are arranged are stretchable, the reinforcing substrates do not impede the stretchability of the flexible substrate or wiring sections. This prevents fluctuations in contact impedance between the electrodes and the skin due to the wearer's body movements, making it possible to perform accurate measurements without increasing the burden on the wearer.

[0037] 4A to 4E show an example of the configuration of an adapter according to a second embodiment of the present invention. Fig. 4A is a cross-sectional view of the adapter 10 at the connector arrangement position, and Figs. 4B to 4E are top views of the adapter 10 as seen from the side where the connector portions (20-1, 20-2) are arranged. In Figs. 4B to 4E, other components such as the flexible substrate 11 are omitted in order to illustrate the arrangement of the reinforcing substrates (13-1 to 13-5).

[0038] In the third embodiment, similarly to the second embodiment, reinforcing substrates (13-1, 13-2) are arranged in regions #1 and #2 (first region, second region) of a predetermined width in which the connector portion (20-1) and the connector portion (20-2) are arranged, and further, reinforcing substrates (13-3 to 13-5) are also arranged in a region #3 (third region) between the regions in which the connector portion (20-1) and the connector portion (20-2) are arranged, and in regions #4 and #5 (fourth region, fifth region) in which the electrode portions (30-1, 30-2) and the wiring portions (40-1, 40-2) are arranged.

[0039] In the third embodiment, compared to the second embodiment, the reinforcing substrates (13-3 to 13-5) arranged in region #3 (third region) between the regions where the connector portion (20-1) and the connector portion (20-2) are arranged, and in regions #4 and #5 (fourth region, fifth region) where the electrode portions (30-1, 30-2) and the wiring portions (40-1, 40-2) are arranged, are divided from the reinforcing substrates (13-1, 13-2) arranged in regions #1 and #2 (first region, second region) of a predetermined width where the connector portion (20-1) and the connector portion (20-2) are arranged.

[0040] According to the third embodiment, as in the second embodiment, even if a relative error occurs in the distance between the connectors of the terminal 50 and the adapter 10, the error can be absorbed on the adapter 10 side, making it possible to easily connect and disconnect the terminal 50 and the adapter 10. Furthermore, fluctuations in contact impedance between the electrodes and the skin due to the wearer's body movements can be prevented, making it possible to perform accurate measurements without increasing the burden on the wearer.

[0041] Furthermore, according to the third embodiment, the reinforcing substrates (13-3 to 13-5) arranged in regions #4 and #5 (fourth region, fifth region) are separated from the reinforcing substrates (13-1, 13-2) arranged in regions #1 and #2 (first region, second region), thereby increasing the degree of freedom when arranging the reinforcing substrates (13-3 to 13-5), thereby achieving the effect of reducing the burden when creating the adapter 10.

[0042] In the first to third embodiments, an embodiment in which a reinforcing base material is arranged in regions #3 to #5 (third to fifth regions) other than regions #1 and #2 (first region and second region) of a predetermined width in which the connector portion (20-1) and the connector portion (20-2) are arranged, and an embodiment in which a reinforcing base material is not arranged have been described. In regions #3 to #5, regions in which a reinforcing base material is arranged and regions in which a reinforcing base material is not arranged may be combined.

[0043] 5A and 5B show examples of the configuration of an adapter according to a fourth embodiment of the present invention. Fig. 5A is a cross-sectional view of the adapter 10 at the connector placement position, and Fig. 5B is a top view of the adapter 10 as seen from the side where the connector portions (20-1, 20-2) are placed. In Fig. 5B, other components such as the flexible substrate 11 are omitted to illustrate the placement of the reinforcing substrates (13-1, 13-2, 13-4, 13-5). Fig. 5B shows an example of a configuration in which the pore structure of the reinforcing substrate is a mesh structure.

[0044] In the fourth embodiment, reinforcing substrates (13-1, 13-2) are arranged in regions #1 and #2 (first region, second region) of a predetermined width in which the connector portion (20-1) and the connector portion (20-2) are arranged, no reinforcing substrate is arranged in region #3 (third region) between the regions in which the connector portion (20-1) and the connector portion (20-2) are arranged, and reinforcing substrates (13-4, 13-5) are arranged in regions #4 and #5 (fourth region, fifth region) in which the electrode portions (30-1, 30-2) and the wiring portions (40-1, 40-2) are arranged.

[0045] In the adapter 10 of this embodiment, as in the first embodiment, the reinforcing substrate (13-3) is not arranged in the region #3 (third region) between the regions where the connector portion (20-1) and the connector portion (20-2) are arranged, so that the distance between the connector portion (20-1) and the connector portion (20-2) is adjustable.

[0046] Fifth Embodiment In the fourth embodiment, the reinforcing substrates (13-4, 13-5) are arranged in regions #4 and #5 (fourth and fifth regions) where the electrode portions (30-1, 30-2) and wiring portions (40-1, 40-2) are arranged. The reinforcing substrate (13-3) may be arranged in region #3 (third region) between the regions where the connector portion (20-1) and the connector portion (20-2) are arranged.

[0047] 6A and 6B show examples of the configuration of an adapter according to a fifth embodiment of the present invention. Fig. 6A is a cross-sectional view of the adapter 10 at the connector placement position, and Fig. 6B is a top view of the adapter 10 as seen from the side where the connector portions (20-1, 20-2) are placed. In Fig. 6B, other components such as the flexible substrate 11 are omitted to illustrate the placement of the reinforcing substrates (13-1, 13-2, 13-4, 13-5). Fig. 6B shows an example of a configuration in which the pore structure of the reinforcing substrate is a mesh structure.

[0048] In the fifth embodiment, reinforcing substrates (13-1, 13-2) are arranged in regions #1 and #2 (first region, second region) of a predetermined width in which the connector portion (20-1) and the connector portion (20-2) are arranged, a reinforcing substrate (13-3) is arranged in region #3 (third region) between the regions in which the connector portion (20-1) and the connector portion (20-2) are arranged, and no reinforcing substrate is arranged in regions #4 and #5 (fourth region, fifth region) in which the electrode portions (30-1, 30-2) and the wiring portions (40-1, 40-2) are arranged.

[0049] In the adapter 10 of this embodiment, similarly to the second embodiment, a reinforcing base material (13-3) is arranged in region #3 (third region) between the regions where the connector portion (20-1) and the connector portion (20-2) are arranged, but since this reinforcing base material (13-3) is elastic, the distance between the connector portion (20-1) and the connector portion (20-2) can be adjusted.

[0050] In addition, in the fourth and fifth embodiments, the reinforcing substrate having a pore structure may be separated from the reinforcing substrate in the area including the connector placement area, as in the third embodiment.

[0051] As explained in the fourth and fifth embodiments, in regions #3 to #5 other than regions #1 and #2 where the connector portion (20-1) and the connector portion (20-2) are arranged, even when regions where a reinforcing substrate is arranged and regions where it is not arranged are combined, the same effects as those of the first to third embodiments can be obtained.
