[0003] [Patent Document 1] International Publication No. 2019 / 065029 Summary of the Invention [Problem to be solved by the invention]

[0004] The biodevice described in Patent Document 1 can prevent water from entering the inside of the case, but does not particularly consider the insulation between the inside and outside of the case. Incidentally, a discharging device such as an electric scalpel or a defibrillator may be used near the part of the user's body where the biodevice is attached. In this case, an electrical shock may be applied from these devices to the biodevice. Therefore, there is a risk that a current may flow from the outside of the case of the biodevice to the electronic unit built into the case of the biodevice. [Means for solving the problem]

[0005] In order to solve the above problems, one aspect of the present disclosure is a biological device comprising a case having a communication hole and wearable on the body, an electronic unit built into the case, an gas-liquid separator attached to the case, and an insulating sheet attached to the case or the electronic unit, wherein the communication hole communicates in a first direction to connect the internal space of the case to the external space, the gas-liquid separator and the insulating sheet are positioned apart in the first direction, and when viewed in a plane facing the first direction, the gas-liquid separator, the electronic unit, and the insulating sheet overlap with the communication hole.

[0006] According to the above configuration, when viewed in a plan view facing the first direction, the gas-liquid separator, the electronic unit, and the insulating sheet overlap with the communication hole, so that the insulating sheet can prevent a current from flowing from the outside of the case to the electronic unit through the communication hole.

[0007] In order to solve the above problems, one aspect of the present disclosure is a biological device comprising a case that can be worn on the body, a gas-liquid separator that forms part of a wall of the case and is arranged to allow gas to pass between an internal space and an external space of the case in a first direction that is the thickness direction of the wall, an electronic unit built into the case, and an insulating sheet attached to the case or the electronic unit, wherein the gas-liquid separator and the insulating sheet are arranged at a distance from each other in the first direction, and when viewed in a plane facing the first direction, the gas-liquid separator, the electronic unit, and the insulating sheet overlap.

[0008] According to the above configuration, when viewed in a plan view facing the first direction, the gas-liquid separator, the electronic unit, and the insulating sheet overlap with the communication hole, so that the insulating sheet can prevent a current from flowing from the outside of the case to the electronic unit via the gas-liquid separator. Effect of the Invention

[0009] This prevents current from flowing from the outside of the case to the electronic unit. [Brief description of the drawings]

[0011] (First embodiment) Hereinafter, a first embodiment of the biodevice will be described with reference to the drawings. In addition, the drawings may show components enlarged for ease of understanding. The dimensional ratios of the components may differ from the actual ones or from those in other drawings.

[0012] As shown in Fig. 1, the biodevice 10 includes a case 20. The case 20 is attachable to the body. As shown in Fig. 2, the case 20 defines an internal space S. The case 20 is made of a material such as a synthetic resin. Therefore, when the case 20 is attached to the skin of the body, it elastically deforms to an extent that it can follow the movement of the skin.

[0013] The case 20 has a circular communication hole 21. The communication hole 21 connects the internal space S with the space outside the case 20. The communication hole 21 opens on a surface of the case 20 that is different from the surface that is attached to the skin. Therefore, even when the biodevice 10 is attached to the body, the communication hole 21 is not blocked by the body.

[0014] The axis that runs along the direction in which the communication hole 21 opens and passes through the center of the opening of the communication hole 21 is defined as a virtual axis AX. Among the directions along the virtual axis AX, the direction from the internal space S toward the external space of the case 20 is defined as a first direction D1. Among the directions along the virtual axis AX, the direction opposite to the first direction D1 is defined as a second direction D2. In other words, the communication hole 21 connects the internal space S of the case 20 to the external space of the case 20 in the first direction D1.

[0015] The biodevice 10 includes an electronic unit 30. The electronic unit 30 is located in the internal space S. Therefore, the electronic unit 30 is built into the case 20. The electronic unit 30 includes, for example, an electronic circuit, a power supply, and an electronic board. In particular, in this embodiment, the electronic unit 30 includes a temperature sensor. That is, the biodevice 10 is a biosensor that detects the temperature of the body by the temperature sensor.

[0016] The electronic unit 30 is located at a position overlapping the communication hole 21 when viewed in a plan view facing the opening direction of the communication hole 21. Specifically, the electronic unit 30 is located on the imaginary axis AX. Moreover, when viewed in a plan view facing the opening direction of the communication hole 21, the electronic unit 30 overlaps with the entire area of ​​the communication hole 21.

[0017] The biodevice 10 includes a gas-liquid separator 40. The gas-liquid separator 40 allows gas to pass through but does not allow liquid water to pass through. Specifically, the material of the gas-liquid separator 40 is polytetrafluoroethylene. The gas-liquid separator 40 has a porous structure. In this specification, "does not allow liquid water to pass through" means that liquid water does not pass through at 0.3 atm. In this embodiment, the water resistance of the gas-liquid separator 40 is 200 kPa. In this embodiment, since the gas-liquid separator 40 has a porous structure, water passes through it if the pressure applied from the outside exceeds the water resistance.

[0018] The gas-liquid separator 40 is attached to the case 20. The gas-liquid separator 40 blocks the communication hole 21. Therefore, the gas-liquid separator 40 blocks the inflow and outflow of water via the communication hole 21. Specifically, the gas-liquid separator 40 has a first spacer 41 and a gas-liquid separating sheet 42. Note that, although the first spacer 41 and the gas-liquid separating sheet 42 are illustrated as separate members in FIG. 2, they may be molded as a single integrated member.

[0019] 1, the first spacer 41 has a circular ring shape. The inner diameter of the first spacer 41 is larger than the diameter of the communication hole 21. When the biodevice 10 is viewed in a plan view in the second direction D2, the first spacer 41 surrounds the communication hole 21 from the outside. The first spacer 41 is attached to the inner surface of the case 20 via an adhesive (not shown).

[0020] As shown in Fig. 2, the gas-liquid separating sheet 42 is attached to the surface of the first spacer 41 facing the second direction D2 via an adhesive (not shown). As shown in Fig. 1, the gas-liquid separating sheet 42 is a circular sheet. The diameter of the gas-liquid separating sheet 42 is larger than the diameter of the communication hole 21. Therefore, when the biodevice 10 is viewed in a plan view facing the second direction D2, the area of ​​the gas-liquid separating sheet 42 is larger than the area of ​​the communication hole 21. Furthermore, when the biodevice 10 is viewed in a plan view facing the second direction D2, the gas-liquid separating sheet 42 overlaps the entire range of the communication hole 21.

[0021] With the above structure, the gas-liquid separator 40 separates the internal space S of the case 20 into a space on the side of the gas-liquid separator 40 where the electronic unit 30 is present and a space on the side where the electronic unit 30 is not present. The gas-liquid separator 40 prevents liquid water from entering the space on the side of the gas-liquid separator 40 where the electronic unit 30 is present, of the internal space S of the case 20, through the communication hole 21. In this way, the gas-liquid separator 40 blocks the communication hole 21 so that liquid water cannot enter the internal space S.

[0022] The biodevice 10 includes two second spacers 50 and an insulating sheet 60. The second spacers 50 are interposed between the inner surface of the case 20 and the insulating sheet 60. The material of each second spacer 50 is, for example, polyethylene terephthalate. That is, each second spacer 50 is made of a material that does not allow gas to pass through. The material of each second spacer 50 is an insulator that does not allow electricity to pass through.

[0023] The dimension of each second spacer 50 in the direction along the virtual axis AX is larger than the maximum dimension of the gas-liquid separator 40 in the direction along the virtual axis AX. When the biodevice 10 is viewed in a plan view in the second direction D2, the two second spacers 50 are located on both sides of the communication hole 21. Therefore, when the biodevice 10 is viewed in a plan view in the first direction D1, the two second spacers 50 are arranged to sandwich the communication hole 21. In addition, the two second spacers 50 are parallel to each other. As a result, a gap is generated between the two second spacers 50. In other words, when the biodevice 10 is viewed in a plan view in the second direction D2, the two second spacers 50 partially surround the communication hole 21. Each second spacer 50 is attached to the inner surface of the case 20 by an adhesive (not shown).

[0024] The second spacer 50 partially surrounding the communication hole 21 refers to a state in which the communication hole 21 is not completely surrounded by the second spacer 50. In other words, when the biodevice 10 is viewed in a plan view facing the second direction D2, if there is a passage from the communication hole 21 to a space outside the second spacer 50 without crossing the second spacer 50, it is said that the second spacer 50 partially surrounds the communication hole 21.

[0025] The insulating sheet 60 is attached to the surface of the second spacer 50 facing the second direction D2 via an adhesive (not shown). Therefore, the insulating sheet 60 is attached to the case 20 via the second spacer 50. The insulating sheet 60 is located at a position away from the communication hole 21 in the direction along the imaginary axis AX. The insulating sheet 60 is also located at a position away from the gas-liquid separator 40 in the direction along the imaginary axis AX. That is, the gas-liquid separator 40 and the insulating sheet 60 are disposed at a distance from each other in the first direction D1. In this way, in the biodevice 10, the electronic unit 30, the insulating sheet 60, the gas-liquid separator 40, and the communication hole 21 are located in this order in the first direction D1.

[0026] The insulating sheet 60 is made of an insulator. Specifically, the insulating sheet 60 is made of polytetrafluoroethylene. The insulating sheet 60 is made of a material that does not allow gas to pass through. Specifically, the insulating sheet 60 does not have a porous structure like the gas-liquid separator 40.

[0027] The insulating sheet 60 is a rectangular sheet. The dimension of one side of the insulating sheet 60 is slightly larger than the longitudinal dimension of each second spacer 50. When the biodevice 10 is viewed in a plan view in the second direction D2, two opposing sides of the insulating sheet 60 are parallel to the longitudinal direction of each second spacer 50. When the biodevice 10 is viewed in a plan view in the second direction D2, the insulating sheet 60 overlaps the entire range of the communication hole 21. In this way, when viewed in a plan view in the first direction D1, the gas-liquid separator 40, the electronic unit 30, and the insulating sheet 60 overlap the communication hole 21.

[0028] Furthermore, when the biodevice 10 is viewed in plan in the second direction D2, the dimension of one side of the insulating sheet 60 is larger than the diameter of the communication hole 21. Therefore, when the biodevice 10 is viewed in plan in the second direction D2, the area of ​​the insulating sheet 60 is larger than the area of ​​the communication hole 21.

[0029] Furthermore, when the biodevice 10 is viewed in plan in the second direction D2, the dimension of one side of the insulating sheet 60 is larger than the diameter of the gas-liquid separation sheet 42. Therefore, when the biodevice 10 is viewed in plan in the second direction D2, the area of ​​the insulating sheet 60 is larger than the area of ​​the gas-liquid separation sheet 42.

[0030] Furthermore, when the biodevice 10 is viewed in plan in the second direction D2, the outer edge of the insulating sheet 60 surrounds the outer edge of the gas-liquid separator 40. In other words, when the biodevice 10 is viewed in plan in the second direction D2, the area of ​​the insulating sheet 60 is larger than the area of ​​the gas-liquid separator 40.

[0031] <Operation of the First Embodiment> The biodevice 10 is used by being attached to the body. When the case 20 of the biodevice 10 is attached to the skin or the like, the case 20 deforms in accordance with the movement of the skin. When the case 20 deforms, the volume of the internal space S of the case 20 changes, and air flows in and out between the internal space S and the external space of the case 20.

[0032] At this time, the gas-liquid separator 40 allows gas to pass through, and therefore the gas-liquid separator 40 does not block the flow of gas through the communication hole 21. In addition, the insulating sheet 60 is separated from the communication hole 21 in the direction along the imaginary axis AX, and therefore the insulating sheet 60 does not block the flow of gas through the communication hole 21.

[0033] <Advantages of the First Embodiment> (1-1) According to the first embodiment, when viewed in a plan view facing the first direction D1, the gas-liquid separator 40, the electronic unit 30, and the insulating sheet 60 overlap with the communication hole 21. Therefore, the insulating sheet 60 can prevent a current from flowing from the external space of the case 20 to the electronic unit 30 through the communication hole 21.

[0034] (1-2) According to the first embodiment, when the biodevice 10 is viewed in a plan view in the second direction D2, the insulating sheet 60 overlaps the entire area of ​​the communication hole 21. This makes it possible to reliably prevent a current from flowing from the external space of the case 20 to the electronic unit 30 through the communication hole 21.

[0035] (1-3) According to the first embodiment, the second spacer 50 partially surrounds the communication hole 21. Therefore, gas can flow in and out through a portion where the second spacer 50 is not provided, and the second spacer 50 does not excessively impede the flow of gas in and out between the external space and the internal space S of the case 20.

[0036] (1-4) According to the first embodiment, the second spacer 50 is disposed to sandwich the communication hole 21 when viewed from the front in the first direction D1. This makes it possible to prevent the case 20 from being deformed so that the gap between the second spacer 50 and the case 20 is crushed.

[0037] (1-5) According to the first embodiment, when the biodevice 10 is seen through in the second direction D2, the area of ​​the insulating sheet 60 is larger than the area of ​​the communication hole 21. This makes it possible to lengthen the path of current traveling from the external space of the case 20 to the electronic unit 30 via the communication hole 21. This makes it possible to prevent current from outside the case 20 from reaching the electronic unit 30.

[0038] (1-6) According to the first embodiment, when the biological device 10 is seen through in the second direction D2, the area of ​​the insulating sheet 60 is larger than the area of ​​the gas-liquid separator 40. Therefore, the path from the external space of the case 20 to the electronic unit 30 via the communication hole 21 can be made longer regardless of the location of the gas-liquid separator 40 through which the path passes. This makes it possible to further prevent current from the outside of the case 20 from reaching the electronic unit 30.

[0039] (1-7) According to the first embodiment, both the insulating sheet 60 and the gas-liquid separator 40 are disposed in the internal space S. Therefore, when the biodevice 10 is worn on the body and used, the insulating sheet 60 and the gas-liquid separator 40 are protected by the case 20 from physical impacts from the external space of the case 20. This prevents the insulating sheet 60 and the gas-liquid separator 40 from being damaged.

[0040] Second embodiment Hereinafter, the second embodiment of the biodevice will be described with reference to the drawings. Note that the following description will focus on the differences from the biodevice 10 in the first embodiment, and details of the same points will be simplified or omitted.

[0041] 3, the second embodiment is different from the first embodiment mainly in that the biodevice 110 does not have the second spacer 50 of the first embodiment and in the arrangement of the insulating sheet 160. The insulating sheet 160 is attached to a surface of the electronic unit 30 facing the first direction D1.

[0042] (2-1) According to the second embodiment, the insulating sheet 160 is attached to the electronic unit 30. Therefore, the second spacer 50 in the first embodiment can be omitted. Also, compared to the first embodiment, it is easier to arrange the insulating sheet 160 and the gas-liquid separator 40 apart from each other than when both the insulating sheet 160 and the gas-liquid separator 40 are attached to the inner surface of the case 20. As a result, the insulating sheet 160 covers the entire gas-liquid separator 40, which makes it easier to prevent the insulating sheet 160 from blocking the flow of gas through the communication hole 21. Also, compared to the case 20, the electronic unit 30 is less likely to deform, so that it is possible to prevent the position of the insulating sheet 160 from shifting due to use.

[0043] Third embodiment Hereinafter, the third embodiment of the biodevice will be described with reference to the drawings. Note that the following description will focus on the differences from the biodevice 10 of the first embodiment, and details of the same points will be simplified or omitted.

[0044] 4, in the third embodiment, the positions of the second spacer 250 and the insulating sheet 260 of the biodevice 210 are different from those of the first embodiment. The second spacer 250 is attached to the outer surface of the case 20 via an adhesive (not shown). In addition, the gap between the two second spacers 250 is narrower than that of the first embodiment.

[0045] The insulating sheet 260 is attached to the surface of the second spacer 250 facing the first direction D1 via an adhesive (not shown). When the biodevice 10 is viewed in the second direction D2, the area of ​​the insulating sheet 260 is smaller than that of the first embodiment. Specifically, the dimension of one side of the insulating sheet 260 is equal to the diameter of the gas-liquid separation sheet 42.

[0046] In this manner, the second spacer 250 and the insulating sheet 260 are disposed in the external space of the case 20. Therefore, the electronic unit 30, the gas-liquid separator 40, the communication hole 21, and the insulating sheet 260 are positioned in this order in the first direction D1.

[0047] (3-1) According to the third embodiment, the insulating sheet 260 can be attached to the outer surface of the case 20 via the second spacer 250. Therefore, compared to the first embodiment, it is not necessary to consider the position of the gas-liquid separator 40 when attaching the insulating sheet 260 to the case 20. This makes it easier to attach the insulating sheet 260 to the case 20.

[0048] (Fourth embodiment) Hereinafter, the fourth embodiment of the biodevice will be described with reference to the drawings. Note that the following description will focus on the differences from the biodevice 210 in the third embodiment, and details of the same points will be simplified or omitted.

[0049] As shown in FIG. 5, in the fourth embodiment, the positions of a second spacer 350 and an insulating sheet 360 of a biodevice 310 and the position of a gas-liquid separator 340 are interchanged compared to the third embodiment.

[0050] Specifically, the first spacer 341 of the gas-liquid separator 340 is attached to the outer surface of the case 20 via an adhesive (not shown). The gas-liquid separating sheet 342 is attached to the surface of the first spacer 341 facing the first direction D1 via an adhesive (not shown).

[0051] Each second spacer 350 is attached to the inner surface of the case 20 via an adhesive (not shown). Also, the insulating sheet 360 is attached to the surface of each second spacer 350 facing the second direction D2 via an adhesive (not shown).

[0052] In this manner, the gas-liquid separator 340 is disposed in the external space of the case 20. Meanwhile, the second spacer 350 and the insulating sheet 360 are disposed in the internal space S of the case 20. Therefore, the electronic unit 30, the insulating sheet 360, the communication hole 21, and the gas-liquid separator 340 are positioned in this order in the first direction D1.

[0053] (4-1) According to the fourth embodiment, the gas-liquid separator 340 can be attached to the outer surface of the case 20. Therefore, compared to the first embodiment, there is no need to consider the position of the insulating sheet 360 when attaching the gas-liquid separator 340 to the case 20. This makes it easier to attach the insulating sheet 360 to the case 20.

[0054] Fifth embodiment Hereinafter, the fifth embodiment of the biodevice will be described with reference to the drawings. Note that the following description will focus on the differences from the biodevice 10 of the first embodiment, and details of the same points will be simplified or omitted.

[0055] As shown in FIG. 6, in the fifth embodiment, the position of the gas-liquid separator 440 of the biodevice 410 is different from that of the first embodiment. Specifically, the gas-liquid separator 440 is accommodated inside the communication hole 21. Particularly, in this embodiment, the gas-liquid separator 440 fills the entire inside of the communication hole 21. As a result, the gas-liquid separator 440 blocks the communication hole 21. Furthermore, the gas-liquid separator 440 exists only inside the communication hole 21. That is, the gas-liquid separator 440 does not protrude to the outside of the communication hole 21. Therefore, in the fifth embodiment, it can be said that the case 20 does not have the communication hole 21. And, a part of the wall of the case 20 is composed of the gas-liquid separator 440. Note that, in the fifth embodiment, gas can pass between the internal space S of the case 20 and the external section of the case 20 in the thickness direction of the wall of the case 20 through the gas-liquid separator 440. Therefore, the thickness direction of the wall of the case 20 at the portion where the gas-liquid separator 440 is formed coincides with the imaginary axis AX.

[0056] In this way, the communication hole 21 and the gas-liquid separator 440 are located at the same position in the direction along the imaginary axis AX. The electronic unit 30, the insulating sheet 60, and the communication hole 21 are located in this order in the first direction D1.

[0057] The dimension of the second spacer 450 of the biodevice 410 in the direction along the imaginary axis AX is smaller than that of the first embodiment. (5-1) According to the fifth embodiment, the space inside the communication hole 21 can be utilized to place the gas-liquid separator 440. Therefore, an excessively large internal space S is not required to provide the gas-liquid separator 440. As a result, the size of the biodevice 410 is easily prevented from increasing.

[0058] (5-2) According to the fifth embodiment, the insulating sheet 60 is disposed in the internal space S. Therefore, the insulating sheet 60 is protected by the case 20 when the biodevice 410 is attached to the body and used.

[0059] (Other embodiments) The above-described embodiments may be modified as follows: The above-described embodiments and the following modifications may be combined and implemented within the scope of technical compatibility.

[0060] The biodevice is not limited to a biosensor as long as it is a device worn on the body. In other words, the electronic unit 30 does not need to have a sensor. In addition, when the biodevice is a biosensor, for example, when the biodevice is attached to the body, a discharging device such as an electric scalpel or a defibrillator is used near the location where the biodevice is attached, so current is likely to enter from the outside of the case 20. Therefore, there is a greater need to obtain the effect of providing an insulating sheet.

[0061] Case 20 may be in the form of a film. In other words, case 20 may only have a degree of rigidity that makes it unable to maintain its shape by itself. In this case, the virtual axis AX when case 20 is worn on the body may be used as the reference.

[0062] The material of the gas-liquid separator is not limited to polytetrafluoroethylene. Any material that allows gas to pass through but does not allow liquid water to pass through may be used. The water resistance of the gas-liquid separator may be 30 kPa or more.

[0063] The shape of the gas-liquid separator may be changed as appropriate as long as it blocks the communication hole 21. For example, in the first embodiment, the gas-liquid separator 40 may be in a block shape. Note that, as in the fifth embodiment, the gas-liquid separator 440 may block the communication hole 21, so that the case 20 does not have the communication hole 21.

[0064] In the first to fourth embodiments, the gas-liquid separator may omit the first spacer as in the fifth embodiment. For example, in the first embodiment, the gas-liquid separating sheet 42 may be attached to the inner surface of the case 20 without the first spacer 41 therebetween.

[0065] The shape of the second spacer is not limited to the examples of the above embodiments. For example, in the first embodiment, when the biodevice 10 is seen through in the second direction D2, the second spacer 50 may be C-shaped or spiral-shaped. In these cases, when the biodevice 10 is seen through in the second direction D2, the second spacer 50 partially surrounds the communication hole 21.

[0066] In the first and third to fifth embodiments, when the biodevice 10 is seen through in the second direction D2, the second spacer may surround the entire communication hole 21. In this case, for example, in the first embodiment, there may be a gap between the insulating sheet 60 and the second spacer 50, or the material of the second spacer 50 may be a material that allows gas to pass through. In this way, when the biodevice 10 is seen through in the second direction D2, it is sufficient that the flow of gas between the space inside the second spacer 50 and the space outside the second spacer 50 is not blocked.

[0067] The material of the second spacer does not have to be an insulator. In the third embodiment, the biodevice 210 may omit the second spacer 250. This also applies to the fourth and fifth embodiments.

[0068] The area of ​​the insulating sheet when the biodevice 10 is seen through in the second direction D2 is not limited to the examples of the above embodiments. For example, in the first embodiment, when the biodevice 10 is seen through in the second direction D2, the area of ​​the insulating sheet 60 may be equal to the area of ​​the communication hole 21. Also, for example, in the first embodiment, when the biodevice 10 is seen through in the second direction D2, the area of ​​the insulating sheet 60 may be equal to or smaller than the area of ​​the gas-liquid separator 40.

[0069] In each embodiment, the arrangement of the electronic unit 30, the insulating sheet, the gas-liquid separator, and the communication hole 21 may be changed so that the order of these in the first direction D1 is changed. When viewed in a plan view facing the first direction D1, the gas-liquid separator, the electronic unit 30, and the insulating sheet may overlap the communication hole 21. Thereby, for example, in the first embodiment, the insulating sheet 60 and the gas-liquid separator 40 may be located in the external space of the case 20.
