Description

[Technical Field]

[0001] The present invention relates to a measuring electrode section and a measuring unit. [Background technology]

[0002] Patent Document 1 discloses an electrocardiogram measuring device that uses a clip. As disclosed in Patent Document 1, the clip is attached so as to clamp the limb. The clip is attached to each of the subject's limbs. In other words, in the electrocardiogram disclosed in Patent Document 1, a clip is attached to each of both hands.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 6-22918 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, veterinary clinics and the like may measure biometric data, such as electrocardiograms, of animals such as small birds. For example, when measuring a bird's electrocardiogram using an electrocardiogram measuring device such as that disclosed in Patent Document 1, it is necessary to clamp the base of the bird's feathers with small clips. However, animals that have difficulty communicating with humans, such as birds, may move violently when their electrocardiograms are measured. For this reason, it is common to measure the electrocardiogram while the bird is sedated with anesthesia so that the clips do not cause pain to the feathers. However, the use of anesthesia also places a burden on animals such as birds. Furthermore, the use of anesthesia changes the heart's movement, making it difficult to accurately understand the heart's movement when the animal is awake.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to make it possible to measure biological data such as electrocardiograms of animals that are difficult to communicate with without sedating the animals. [Means for solving the problem]

[0006] The present invention employs the following configuration as a means for solving the above problems.

[0007] A first aspect of the present invention is a measurement electrode unit that is connected to a measurement main body unit that creates biological data based on an input signal and is used by contacting the body surface of an animal, and has a body surface contact surface that can be pressed against the body surface and a pressing surface that is located on the opposite side of the body surface from the body surface contact surface, and is configured so that the body surface contact surface can be pressed against the body surface by pressing the pressing surface.

[0008] A second aspect of the present invention is the first aspect, and further comprises a coil-shaped portion made of a conductor and formed in a coil shape that can be attached to the finger of a person using the measuring main body, wherein the radially outer surface of the coil-shaped portion is the body surface contact surface, and the radially inner surface of the coil-shaped portion is the pressing surface.

[0009] A third aspect of the present invention is the second aspect, which has a configuration in which wiring connected to the measuring main body portion can be attached and which has an attachment portion connected to the coil-shaped portion.

[0010] A fourth aspect of the present invention is the third aspect, wherein the attachment portion is formed by a portion of the wire that forms the coil-shaped portion being drawn out from the coil-shaped portion.

[0011] A fifth aspect of the present invention adopts a configuration in which, in the third aspect, one end of the wiring for the electrode portion is connected to the coil-shaped portion, and the mounting portion is provided at the other end of the wiring for the electrode portion.

[0012] A sixth aspect of the present invention is the third aspect, wherein the mounting portion has a rod member made of a conductor and fixed to the coil-shaped portion, and a wiring connection portion that is detachable from the tip of the rod member and to which the wiring is fixed.

[0013] A seventh aspect of the present invention is a measurement unit comprising a measurement electrode section according to any one of the first to sixth aspects, the measurement main body section, and wiring connecting the measurement main body section and the measurement electrode section.

[0014] An eighth aspect of the present invention is the seventh aspect, wherein the measuring electrode portion and the wiring are provided in plural. [Effects of the Invention]

[0015] According to the present invention, by pressing the pressing surface provided on the opposite side to the body surface contact surface, the body surface contact surface of the measurement electrode unit can be pressed against the body surface of the animal. Therefore, it is possible to measure biological data such as an electrocardiogram while restraining an awake animal by holding it via the measurement electrode unit. Therefore, according to the present invention, it is possible to measure biological data such as an electrocardiogram of an animal that is difficult to communicate with without sedating the animal.

[0017] Hereinafter, an embodiment of a measuring electrode section and a measuring unit according to the present invention will be described with reference to the drawings.

[0018] (First embodiment) FIG. 1 is a schematic diagram showing the overall configuration of an electrocardiograph unit 100 (measurement unit) according to this embodiment. The electrocardiograph unit 100 according to this embodiment is suitable for measuring the electrocardiogram (biological data) of small animals such as small birds. However, the subject for measuring the electrocardiogram with the electrocardiograph unit 100 according to this embodiment is not limited to small birds; any animal that has difficulty communicating can be used as a subject for electrocardiogram measurement. For example, the electrocardiograph unit 100 according to this embodiment can measure the electrocardiogram of a dog or a cat. The electrocardiograph unit 100 according to this embodiment can also measure the electrocardiogram of companion animals such as hamsters, rabbits, guinea pigs, ferrets, and sugar gliders. The electrocardiograph unit 100 according to this embodiment can also measure the electrocardiogram of small laboratory animals such as mice and rats. The electrocardiograph unit 100 according to this embodiment can also measure the electrocardiogram of reptiles and amphibians. The electrocardiograph unit 100 according to this embodiment can also measure the electrocardiogram of newborns, infants, young children, and children.

[0019] In addition, in this embodiment, an example will be described in which the measurement unit of the present invention is an electrocardiograph unit 100. However, the measurement unit of the present invention can be applied to any measurement unit that measures biological data of an animal. For example, the measurement unit of the present invention can be applied to a body composition monitor unit that measures body composition data as biological data, an electromyograph unit that measures electromyogram data as biological data, and an electroencephalograph unit that measures electroencephalogram data as biological data.

[0020] As shown in FIG. 1, the electrocardiograph unit 100 of this embodiment includes two coil-shaped electrode portions 1 (measurement electrode portions), two clip-shaped electrode portions 2, four signal lines 3 (wiring), and an electrocardiograph main body 4 (measurement main body portion).

[0021] Each coiled electrode unit 1 is connected to an electrocardiograph main body 4 via a signal line 3. As shown in FIG. 2, each coiled electrode unit 1 is used while being attached to the fingers of the person performing the measurement, such as a veterinarian. For example, one coiled electrode unit 1 is attached to the index finger of the person performing the measurement. The other coiled electrode unit 1 is attached to the middle finger of the person performing the measurement. However, the fingers on which the coiled electrode unit 1 is attached are not particularly limited. The fingers on which the coiled electrode unit 1 is attached can be changed depending on the size of the animal to be measured. For example, when a large bird is to be measured, the coiled electrode unit 1 may be attached to the thumb and index finger.

[0022] These coiled electrodes 1 must be insulated from the person being measured. For this reason, the person being measured puts on insulating gloves before putting on the coiled electrodes 1. However, for example, if the surface of the coiled electrodes 1 that comes into contact with the person being measured is insulated, the person being measured can put on the coiled electrodes 1 without putting on gloves.

[0023] FIG. 3 is a perspective view of one coiled electrode unit 1. Each coiled electrode unit 1 is used by being in contact with the body surface of an animal. In this embodiment, the coiled electrode unit 1 is used by being pressed against the body surface of an animal without clamping any part of the animal. As shown in FIG. 3, such a coiled electrode unit 1 has a coil-shaped portion 1a and an attachment portion 1b.

[0024] The coil-shaped portion 1a is formed into a cylindrical coil shape by spirally winding a wire 1c made of a conductive material such as copper around a central axis L. In other words, the coil-shaped portion 1a is made of a conductive material. The inner diameter of the coil-shaped portion 1a is set to a size that allows the subject's finger to be easily inserted and prevents the inserted finger from easily slipping out. For example, multiple types of coil-shaped electrode portions 1 with different inner diameters of the coil-shaped portion 1a may be prepared in advance so as to be compatible with the size of the subject's finger.

[0025] Fig. 4 is a partial cross-sectional view of the coil-shaped portion 1a. The outer peripheral surface 1a1 (radially outer surface) of the coil-shaped portion 1a shown in Fig. 4 is a body surface contact surface that can be pressed against the body surface of an animal. In other words, at least a part of the outer peripheral surface 1a1 of the coil-shaped portion 1a is pressed against the body surface of an animal when an electrocardiogram is obtained.

[0026] The inner circumferential surface 1a2 (radially inner surface) of the coil-shaped portion 1a is a pressing surface located on the opposite side of the body surface with respect to the body surface contact surface. That is, when acquiring an electrocardiogram, at least a part of the inner circumferential surface 1a2 of the coil-shaped portion 1a is pressed so that a part of the outer circumferential surface 1a1 is pressed against the body surface. In this embodiment, when the measurer's fingers press the inner circumferential surface 1a2, a part of the outer circumferential surface 1a1 is pressed against the body surface.

[0027] The length of the coil-shaped portion 1a (the size in the direction along the central axis L) is such that it spans, for example, the second joint of the subject's finger. As described above, the coil-shaped portion 1a is formed by spirally winding the wire 1c, and therefore can change shape in a direction inclined relative to the central axis L. Therefore, even when the coil-shaped portion 1a is worn so as to span the second joint of the subject's finger, it does not hinder the subject's bending motion of the finger. Note that, for example, in order to further increase the range of motion of the subject's finger or improve wearing comfort, the coil-shaped portion 1a may be formed so that the distance between the wires 1c in the portion covering the second joint is wider than in other portions.

[0028] 3, the attachment portion 1b is connected to the coil-shaped portion 1a and is a portion to which the signal line 3 can be attached. In this embodiment, the attachment portion 1b is formed by bending a portion of the wire material 1c. In other words, the attachment portion 1b is formed by a portion of the wire material 1c that forms the coil-shaped portion 1a being pulled out from the coil-shaped portion 1a.

[0029] 3, in this embodiment, the attachment portion 1b is provided so as to protrude radially outward from a midpoint in the length direction of the coil-shaped portion 1a. However, the attachment portion 1b may also be provided at an end portion in the length direction of the coil-shaped portion 1a. The connection position of the attachment portion 1b to the coil-shaped portion 1a is not particularly limited, but it is preferable that the signal line 3 can be easily connected when the measurer wearing the coil-shaped electrode portion 1 is holding the animal.

[0030] The clip-shaped electrode 2 is a clip-shaped electrode for clamping a part of an animal. In this embodiment, two clip-shaped electrodes 2 are provided. Each clip-shaped electrode 2 is connected to an electrocardiograph main body 4 via a signal line 3.

[0031] In this embodiment, as described above, four electrode units (two coil-shaped electrode units 1 and two clip-shaped electrode units 2) are provided. This is because it is assumed that two of the four electrode units are coil-shaped electrode units 1, allowing the animal to be held by the measurer's hand. In other words, as shown in FIG. 2 , if the animal can be held in an awake state by one hand of the measurer wearing two coil-shaped electrode units 1, the remaining two electrode units may be clip-shaped electrode units 2. However, in the present invention, only one of the multiple electrode units may be a coil-shaped electrode unit 1. Also, three or more of the multiple electrode units may be coil-shaped electrode units 1. Furthermore, all of the multiple electrode units may be coil-shaped electrode units 1.

[0032] The signal lines 3 are wires that connect the electrode units to the electrocardiograph main body 4, and are provided for each electrode unit. These signal lines 3 transmit electrical signals related to the movement of the heart detected by the electrode units to the electrocardiograph main body 4.

[0033] In this embodiment, the signal lines 3 include a signal line 3a for the coiled electrode portion that connects the coiled electrode portion 1 and the electrocardiograph main body 4, and a signal line 3b for the clipped electrode portion that connects the clipped electrode portion 2 and the electrocardiograph main body 4.

[0034] The coiled electrode signal line 3a is a signal line 3 that connects the coiled electrode unit 1 and the electrocardiograph main body 4. The coiled electrode signal line 3a transmits electrical signals related to cardiac activity detected by the coiled electrode unit 1 to the electrocardiograph main body 4. The coiled electrode signal line 3a also has a connecting portion 3a1 for connecting to the attachment portion 1b of the coiled electrode unit 1. In this embodiment, the connecting portion 3a1 is formed in a clip shape and is provided at the end of the coiled electrode signal line 3a. The coiled electrode signal line 3a is electrically connected to the coiled electrode unit 1 by clamping the attachment portion 1b with the clip-shaped connecting portion 3a1.

[0035] The clip-type electrode signal line 3b is a signal line 3 that connects the clip-type electrode 2 to the electrocardiograph main body 4. The clip-type electrode signal line 3b transmits electrical signals related to cardiac activity detected by the clip-type electrode 2 to the electrocardiograph main body 4. The end of this clip-type electrode signal line 3b is fixed to the clip-type electrode 2 in advance.

[0036] The electrocardiograph main body 4 creates electrocardiogram data based on the input signal input via the signal line 3. The electrocardiogram data here means data necessary for creating an electrocardiogram. For example, the electrocardiograph main body 4 is equipped with an output device such as a display or a printer, and visualizes and outputs the electrocardiogram data.

[0037] Next, an example of the operation of measuring an electrocardiogram of a small bird using the electrocardiograph unit 100 of this embodiment will be described.

[0038] First, with the coiled electrode 1 detached from the coiled electrode signal line 3a, the two coiled electrodes 1 are attached to the gloved fingers of the subject. Next, the bird's feathers are parted using a conductive coating agent to expose the bird's skin. Then, the conductive coating agent is applied to either or both of the bird's skin and the coiled electrodes 1.

[0039] Such a conductive coating agent can be produced by mixing, for example, ultrapure water, ethanol, Hibiden alcohol, neutral electrolyzed water, electrocardiogram cream, and ultrasound gel. More specifically, potential conductive coating agents include "a material made by mixing ethanol and neutral electrolyzed water in equal proportions," "a material made by mixing ethanol and Hibiden alcohol in equal proportions," "a material made by mixing ethanol and electrocardiogram cream in equal proportions," "a material made by mixing ethanol and ultrasound gel in equal proportions," "a material made by mixing Hibiden alcohol and neutral electrolyzed water in equal proportions," "a material made by mixing Hibiden alcohol and electrocardiogram cream in equal proportions," "a material made by mixing Hibiden alcohol and ultrasound gel in equal proportions," "a material made by mixing neutral electrolyzed water and electrocardiogram cream in equal proportions," "a material made by mixing neutral electrolyzed water and ultrasound gel in equal proportions," and "a material made by mixing electrocardiogram cream and ultrasound gel in equal proportions."

[0040] A particularly suitable conductive coating for separating the bird's feathers is a "material made by mixing equal parts Hibiden alcohol and neutral electrolyzed water." Also, a suitable conductive coating for applying to the bird's skin and / or the coiled electrode 1 is a "material made by mixing equal parts Suzuken's ECG cream and ultrasound gel."

[0041] Next, the small bird X is restrained as shown in FIG. 5. FIG. 5 is a schematic diagram showing the state in which the small bird X is fixed. As shown in this figure, the measurer holds the small bird X by pinching its head from the dorsal side between the index finger and middle finger, to which the coiled electrode portion 1 is attached. At this time, the measurer applies pressure to the inner circumferential surface 1a2 of the coil-shaped portion 1a, causing the outer circumferential surface 1a1 of the coil-shaped portion 1a to be pressed against the body surface X1 of the small bird X. By restraining the small bird X in this manner, the movement of the small bird X can be suppressed even when the small bird X is awake. The restraining method shown in FIG. 5 is a common restraining method known as a "Ringer's hold." In other words, according to the electrocardiograph unit 100 of this embodiment, it is possible to measure an electrocardiogram while the small bird is restrained using a common restraining method.

[0042] Furthermore, the connection portion 3a1 of the signal wire 3a for the coiled electrode portion is connected to the attachment portion 1b of the coiled electrode portion 1, and the signal wires 3b for the clipped electrode portion are connected to each of the legs of the small bird X. In this state, the electrocardiogram of the small bird X is measured.

[0043] The coiled electrode unit 1 of this embodiment as described above is connected to an electrocardiograph main body 4 that creates electrocardiogram data based on input signals, and is used by being in contact with the body surface of an animal, and has a body surface contact surface (outer circumferential surface 1a1) that can be pressed against the body surface, and a pressing surface (inner circumferential surface 1a2) located on the opposite side of the body surface from the body surface contact surface. Furthermore, the coiled electrode unit 1 of this embodiment can press the body surface contact surface (outer circumferential surface 1a1) against the body surface by pressing the pressing surface (inner circumferential surface 1a2).

[0044] According to the coiled electrode unit 1 of this embodiment, the body surface contacting surface (outer peripheral surface 1a1) of the coiled electrode unit 1 can be pressed against the body surface of an animal by pressing the pressing surface (inner peripheral surface 1a2) provided on the opposite side to the body surface contacting surface (outer peripheral surface 1a1). Therefore, it is possible to measure the electrocardiogram of an awake animal while restraining it by holding it down via the coiled electrode unit 1 as shown in FIG. 5, for example. Therefore, according to the coiled electrode unit 1 of this embodiment, it is possible to measure the electrocardiogram of an animal that is difficult to communicate with without sedating the animal.

[0045] The coiled electrode unit 1 of this embodiment has a coil-shaped portion 1a made of a conductor. The coil-shaped portion 1a is formed in a coil shape that can be worn on the finger of a person using the electrocardiograph main body 4. An outer peripheral surface 1a1 of the coil-shaped portion 1a is a body surface contact surface, and an inner peripheral surface 1a2 of the coil-shaped portion 1a is a pressing surface.

[0046] According to the coil-shaped electrode portion 1 of this embodiment, the measurer can insert his / her fingers inside the coil-shaped portion 1a and press the fingers against the body surface of the animal, thereby easily and reliably pressing the outer surface 1a1 of the coil-shaped portion 1a against the body surface of the animal.

[0047] Furthermore, the coiled electrode portion 1 of this embodiment has an attachment portion 1b to which a signal line 3 connected to the electrocardiograph main body 4 can be attached. The attachment portion 1b is connected to the coiled portion 1a.

[0048] According to the coiled electrode unit 1 of this embodiment, it is possible to handle the coiled electrode unit 1 with the signal wire 3 detached. This makes it possible to improve the operability of the coiled electrode unit 1.

[0049] Furthermore, in the coiled electrode 1 of this embodiment, the attachment portion 1b is formed by a portion of the wire that forms the coiled portion 1a being pulled out from the coiled portion 1a. According to the coiled electrode 1 of this embodiment, the attachment portion 1b can be formed from the same wire 1c as the coiled portion 1a. This makes it possible to easily form the attachment portion 1b.

[0050] Fig. 6 is an electrocardiogram obtained when the cockatiel was sedated with a sedative. Fig. 7 is an electrocardiogram obtained when the cockatiel was awake using the electrocardiograph unit 100 of this embodiment. Fig. 8 is an electrocardiogram obtained when the cockatiel was sedated with a sedative. Fig. 9 is an electrocardiogram obtained when the cockatiel was awake using the electrocardiograph unit 100 of this embodiment.

[0051] As can be seen from a comparison of the electrocardiograms in FIGS. 7 and 9, the electrocardiograph unit 100 using the coiled electrode section 1 of this embodiment can stably measure electrocardiograms even for different bird species.

[0052] Furthermore, as can be seen from a comparison between Figures 6 and 7 and between Figures 8 and 9, it was found that the arrhythmias and baseline instability observed under sedation can be reduced by the electrocardiograph unit 100 using the coiled electrode portion 1 of this embodiment.

[0053] Furthermore, the electrocardiograph unit 100 of this embodiment includes a coiled electrode section 1, an electrocardiograph main body 4, and a signal line 3 that connects the electrocardiograph main body 4 and the coiled electrode section 1. Therefore, similar to the coiled electrode section 1 of this embodiment, the electrocardiograph unit 100 of this embodiment can measure the electrocardiogram of animals that are difficult to communicate with, without sedating the animal.

[0054] Furthermore, the electrocardiograph unit 100 of this embodiment includes a plurality of coiled electrode sections 1. This allows the number of locations where the animal is clamped to be reduced, thereby reducing the burden on the animal.

[0055] (Second embodiment) Next, a second embodiment of the present invention will be described with reference to Fig. 10. In the description of this embodiment, the description of the same parts as those in the first embodiment will be omitted or simplified.

[0056] 10 is a perspective view of the coiled electrode portion 1A of this embodiment. As shown in this figure, the coiled electrode portion 1A of this embodiment has an electrode portion wiring 1d connected to an end of the coiled portion 1a. The coiled electrode portion 1A of this embodiment also has a plug 1e (attachment portion) connected to the electrode portion wiring 1d.

[0057] One end of the electrode wiring 1d is connected to the coil-shaped portion 1a, and the other end is connected to the plug 1e. That is, the plug 1e is provided at the other end of the electrode wiring 1d. In this embodiment, a jack 3a2 is provided at the end of the coil-shaped electrode signal line 3a. The plug 1e is detachable from the jack 3a2. By attaching the plug 1e to the jack 3a2, the coil-shaped electrode 1A of this embodiment and the electrocardiograph main body 4 are electrically connected.

[0058] According to the coiled electrode portion 1A of this embodiment, the coiled electrode portion 1A can be attached and detached by using the plug 1e and the jack 3a2, which makes it easy to attach and detach the coiled electrode portion 1A.

[0059] Furthermore, the plug 1e is connected to the coil-shaped portion 1a via the electrode wiring 1d. Therefore, even if the position of the coil-shaped portion 1a is unstable due to the movement of the restrained animal, the plug 1e can be prevented from moving. This makes it easy to connect the coil-shaped electrode portion 1A.

[0060] In this embodiment, the coiled electrode portion 1A is provided with a plug 1e. However, the present invention is not limited to this. For example, a jack may be provided on the coiled electrode portion 1A, and a plug may be provided on the end of the coiled electrode portion signal line 3a.

[0061] (Third embodiment) Next, a third embodiment of the present invention will be described with reference to Fig. 11. In the description of this embodiment, the description of the same parts as those in the first embodiment will be omitted or simplified.

[0062] 11 is a perspective view of the coiled electrode portion 1B of this embodiment. As shown in this figure, the coiled electrode portion 1B of this embodiment has a rod member 1f fixed to the coil-shaped portion 1a. The rod member 1f is made of a conductor like the coil-shaped portion 1a, and is located radially outward of the coil-shaped portion 1a.

[0063] The coiled electrode 1B also has a wiring connection 1g that is detachable from the tip of the rod member 1f. The wiring connection 1g is made of a conductor, just like the rod member 1f, and is formed in a cylindrical shape into which the rod member 1f can be inserted. A coiled electrode signal line 3a is fixed to the wiring connection 1g.

[0064] The rod member 1f and the wiring connection portion 1g constitute an attachment portion for attaching the coiled electrode signal wire 3a. In other words, in this embodiment, a portion of the attachment portion is detachable, and the coiled electrode portion 1B can be removed by detaching the portion of the attachment portion. According to the coiled electrode portion 1B of this embodiment, the coiled electrode portion 1B can be easily removed regardless of the shape of the coiled electrode signal wire 3a.

[0065] While the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to the above-described embodiments. The shapes and combinations of the components shown in the above-described embodiments are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present invention.

[0066] For example, in the above embodiment, the measurement electrode unit is described as a coiled electrode unit. However, the present invention is not limited to this. FIG. 12 is a schematic diagram showing a flat measurement electrode unit 10. For example, it is also possible to use a measurement electrode unit 10 in which one surface is a body surface contact surface 10a and the other surface is a pressing surface 10b. In such a case, as shown in FIG. 12, the measurement electrode unit 10 can be attached to a restraint device Y for restraining an animal in an awake state.

[0067] 13, for example, a flat-plate-shaped measuring electrode unit 10 can be attached to a perch Z. In such a case, the surface facing outward from the perch becomes the pressing surface 10b. Alternatively, as shown in FIG. 14, a box 20 can be used in which a wall 22 can be moved toward a small bird X by an actuator 21, and the measuring electrode unit 10 (not shown in FIG. 14) can be attached to the wall 22.
