Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the conventional device fixture and the like, since the electrode of the electrocardiogram measuring device is attached to the cow to measure the electrocardiogram, there is a problem that the electrode is displaced by the movement of the cow and the electrocardiogram of the cow cannot be measured stably for a long time. In particular, since the device fixture of Patent Document 1 provides a holding member for holding the electrode of the electrocardiogram measuring device at a site along the backbone of the cow, for example, when the cow lies on its side, the holding member may shift to the left and right of the cow.

[0005] An object of the present invention is to provide a device fixture capable of stably measuring the electrocardiogram of a cow for a long time, and an electrocardiogram measuring system.

Means for Solving the Problems

[0006] The problems that this invention aims to solve are described above, and the means for solving these problems will now be explained.

[0007] In other words, the device fixing device of the present invention is a device fixing device for fixing an electrocardiogram measuring device for measuring the electrocardiogram of a cow to a cow, and the electrocardiogram measuring device electrodes Hold Strip-shaped including electrode holder A retaining member and It is separate from the retaining member, and is connected to both ends of the strip-shaped retaining member, and is wrapped around the cow's spine. It comprises a fixing member for fixing the holding member to the cow's body, The electrode holder is made heavier than the fixing member and is positioned on the underside of the cow's body so that when the entire device fixing frame is attached to the cow's body and the electrocardiogram measuring device is fixed to the cow, the center of gravity of the entire device fixing frame is located on the underside of the cow. It is a device fixing device.

[0008] With this configuration, the center of gravity of the device fixing device is located on the underside of the cow, creating a sense of weight in the part of the device fixing device that is on the underside of the cow. This makes the entire device fixing device less likely to move relative to the cow, and the electrodes of the electrocardiogram measurement device are less likely to shift. Furthermore, with this configuration, the electrode holder that holds the electrodes of the electrocardiogram measuring device is made heavier than the weight of the fixing member and fixed to the underside of the cow's body. This creates a sense of weight in the electrode holder attached to the lower side of the cow's body, making it difficult for the electrode holder to move relative to the cow and preventing the electrodes from shifting.

[0013] Furthermore, the device fixing device of the present invention may be a device fixing device in which the fixing member is composed of an expandable and contractible member.

[0014] This configuration allows the device fasteners to be securely attached to the cow regardless of the cow's body shape.

[0015] Furthermore, the device fixing device of the present invention may be a device fixing device in which the holding member has a connecting portion for connecting the holding member and the fixing member, and the connecting portion is formed in a bifurcated shape.

[0016] This configuration improves the fit of the device fasteners to the cattle.

[0017] Furthermore, the device fixing device of the present invention may be a device fixing device in which the holding member holds the main body of the electrocardiogram measuring device and also includes a main body holding portion that covers the connecting portion.

[0018] This configuration allows the main body of the electrocardiogram measuring device to be held, while also preventing the connecting part from coming into contact with the cow's skin.

[0019] Further, the device fixture of the present invention may be a device fixture in which the holding member is fixed to the chest of the cow located immediately behind the front leg of the cow by the fixing member.

[0020] With such a configuration, the electrode can be stably held for a long time at a position optimal for measuring the electrocardiogram of the cow.

[0021] Further, the electrocardiogram measurement system of the present invention is an electrocardiogram measurement system including an electrocardiogram measurement device that acquires the electrocardiogram of a cow and the device fixture of the present invention that fixes the electrocardiogram measurement device to the cow.

[0022] With such a configuration, the electrocardiogram of the cow can be measured easily and stably for a long time.

Effects of the Invention

[0023] According to the device fixture of the present invention, displacement of the electrode of the electrocardiogram measurement device is less likely to occur due to the movement of the cow, so that the electrocardiogram of the cow can be measured stably for a long time.

Modes for Carrying Out the Invention

[0025] Hereinafter, an embodiment of the present invention, including the device fixing device and the electrocardiogram measurement system, will be described with reference to the drawings. However, the device fixing device and the electrocardiogram measurement system are not limited to the electrocardiogram measurement system 10 and the device fixing device 30 described below.

[0026] First, we will describe the electrocardiogram measurement system including the device fixing device 30.

[0027] As shown in Figure 1, the electrocardiogram measurement system 10 is a system installed on the torso of a cow U to measure the electrocardiogram of the cow U. The torso of the cow U refers to the trunk portion of the cow U in a normal standing position, having an outer surface formed by the left and right sides, the dorsal side, and the ventral side. The electrocardiogram measurement system 10 measures the electrocardiogram of the cow U to obtain an electrocardiogram waveform used, for example, to determine hypocalcemia in the cow U. The cow U is, for example, a Holstein dairy cow. The electrocardiogram measurement system 10 comprises an electrocardiogram measurement device 20 and a device fixing device 30.

[0028] The electrocardiogram measurement device 20 is a device for measuring the electrocardiogram of a cow U. The electrocardiogram measurement device 20 comprises a device body 21 and electrodes 22.

[0029] The main unit 21 is the main body of the electrocardiogram measuring device 20. The main unit 21 acquires the electrocardiogram of the cow U detected by the electrode 22. The main unit 21 transmits the acquired electrocardiogram to a terminal device (not shown), for example.

[0030] Electrode 22 is a component that detects the electrocardiogram of the cow U. Electrode 22 is electrically connected to the device body 21 via wiring 23 (see Figure 4). Electrode 22 transmits the detected electrocardiogram of the cow U to the device body 21 via wiring 23. The portion of electrode 22 that contacts the body of the cow U is made of, for example, a film-like conductive material. Electrode 22 includes a first electrode 22A, a second electrode 22B, and a third electrode 22C.

[0031] The first electrode 22A is, for example, a positive electrode. The second electrode 22B is, for example, a negative electrode. The third electrode 22C is, for example, a ground electrode.

[0032] Next, the device fixing device 30 will be described.

[0033] As shown in Figure 1, the device fixing device 30 is a fixing device for fixing the electrocardiogram measurement device 20 to the cow U. The device fixing device 30 is attached to the torso of the cow U. The device fixing device 30 is attached by wrapping it around the torso of the cow U. When the device fixing device 30 is attached to the torso of the cow U, the center of gravity is positioned on the underside of the cow U. The underside of the cow U refers to the outer peripheral surface of the abdominal side of the cow U that is located between the forelegs and hind legs of the cow U when the cow U is in a normal standing position and faces the ground. The abdomen of the cow U refers to the outer peripheral portion formed on the lower side of the torso that is located behind the posterior edge of the forelegs and in front of the anterior edge of the hind legs when the cow U is in a normal standing position.

[0034] As shown in Figures 1, 2A, and 2B, the device fixing device 30 includes a holding member 31, a fixing member 38, and a cover member 43. The device fixing device 30 is formed in a strip shape by connecting the holding member 31 and the fixing member 38, and covering the connected portion with a part of the holding member 31 (a main body holding portion 36, described later) and the cover member 43.

[0035] The retaining member 31 is a member that holds the electrocardiogram measuring device 20. The retaining member 31 is formed in a strip shape. When the retaining member 31 is attached to the torso of the cow U, it is fixed to the underside of the torso of the cow U by the fixing member 38. The underside of the torso of the cow U refers to the outer circumferential surface of the torso of the cow U in a normal standing position, including at least the ventral side that faces vertically downward. More specifically, when the device fixing device 30 is attached to the torso of the cow U in a normal standing position, the retaining member 31 is wrapped around the torso of the cow U so as to follow the position of one shoulder on the left or right side of the cow U, through the chest of the cow U, to the position of the other shoulder on the left or right side of the cow U. The chest of the cow U refers to the outer circumferential surface that is located from the front edge to the rear edge of the forelegs when the cow U is in a normal standing position, and is formed on the front and lower side of the torso. The retaining member 31 is fixed to the torso of the cow U located directly behind the forelegs of the cow U by the fixing member 38. The area immediately behind the forelegs of cow U refers to the outer circumferential surface of the torso, adjacent to the posterior edge of the forelegs and located on the posterior side of cow U when cow U is in a normal standing position.

[0036] The holding member 31 includes an electrode holding portion 32, a connecting portion 34, and a main body holding portion 36.

[0037] The electrode holder portion 32 is the part that holds the electrodes 22 of the electrocardiogram measuring device 20. The electrode holder portion 32 is formed in a strip shape. The electrode holder portion 32 is made of a material that has cushioning properties so as not to damage the skin of the cow U when the device fixing device 30 is attached to the cow U's body. The electrode holder portion 32 is made heavier than the fixing member 38 by having a predetermined thickness. When the device fixing device 30 is attached to the cow U's body in a normal standing position, the electrode holder portion 32 is fixed to the underside of the cow U's body by the fixing member 38. By making the electrode holder portion 32 heavier than the fixing member 38 and fixing it to the underside of the cow U's body, the center of gravity is located on the underside of the cow U when the device fixing device 30 is attached to the cow U's body.

[0038] As shown in Figures 3A and 3B, the electrode holding portion 32 has a first surface 32a and a second surface 32b.

[0039] The first surface 32a is the surface that contacts the body of the cow U when the device fixing device 30 is attached to the body of the cow U. As shown in Figure 3A, the electrode holding portion 32 holds the electrode 22 on the first surface 32a side. The electrode holding portion 32 holds the first electrode 22A, the second electrode 22B, and the third electrode 22C on the first surface 32a side. For example, the portion of the electrode holding portion 32 that holds the electrode 22 (first electrode 22A, second electrode 22B, and third electrode 22C) is made of a film-like conductive material.

[0040] The electrode holder 32 holds the first electrode 22A and the second electrode 22B such that when the device fixing device 30 is attached to the torso of the cow U, the heart of the cow U is positioned between horizontal plane H1 (see Figures 1 and 6) and horizontal plane H2 (see Figures 1 and 6). Here, horizontal plane H1 is the horizontal plane containing the center of the first electrode 22A. Horizontal plane H2 is the horizontal plane containing the center of the second electrode 22B. Both horizontal planes H1 and horizontal plane H2 are defined when the device fixing device 30 is attached to the torso of the cow U.

[0041] More specifically, the electrode holder 32 holds the first electrode 22A so that the first electrode 22A is located between the left side of the cow U's chest (right side in Figure 6, hereafter the same) and the left side of the cow U's elbow. The electrode holder 32 also holds the second electrode 22B so that the second electrode 22B is located between the left side of the cow U's elbow and the left side of the cow U's shoulder.

[0042] The electrode holder 32 holds the third electrode 22C between the left elbow of the cow U and the left shoulder of the cow U, at a position closer to the shoulder than the position where the second electrode 22B is positioned. The position in which the electrode holder 32 holds the third electrode 22C is not particularly limited on the electrode holder 32, except for the position where it is sandwiched between the first electrode 22A and the second electrode 22B.

[0043] The second surface 32b is the surface that does not come into contact with the body of the cow U when the device fixing device 30 is attached to the body of the cow U. The electrode holding portion 32 holds the connectors of the electrodes 22 on the second surface 32b side. The electrode holding portion 32 holds the first connector 22a, which is the connector of the first electrode 22A, the second connector 22b, which is the connector of the second electrode 22B, and the third connector 22c, which is the connector of the third electrode 22C, on the second surface 32b side.

[0044] The electrode holding portion 32 has a connector protection portion 33 on the second surface 32b side that protects the first connector 22a, the second connector 22b, the third connector 22c, and the wiring 23 (see Figure 4). The connector protection portion 33 is formed on the second surface 32b so as to cover the first connector 22a, the second connector 22b, the third connector 22, and the wiring 23. The connector protection portion 33 has an opening 33a that can be opened and closed. The opening 33a is constructed, for example, by a fastener.

[0045] As shown in Figures 2B and 3A, the connecting portion 34 is a part for connecting the holding member 31 and the fixing member 38. The connecting portion 34 is detachable from the fixing member 38. The connecting portion 34 is a strip-shaped portion extending from one end and the other end of the electrode holding portion 32. The tip of the strip-shaped portion of the connecting portion 34 is formed in a bifurcated shape. The connecting portion 34 is provided with a holding-side engaging member 35 at each of the tips of the bifurcated strip-shaped portion.

[0046] The retaining-side engaging member 35 is a member for connecting the retaining member 31 (connecting portion 34) and the fixing member 38. The retaining-side engaging member 35 is formed from a lightweight and strong material such as resin or carbon fiber. The material of the retaining-side engaging member 35 differs depending on the configuration of the engaging member on the fixing member 38 side. For example, if the engaging member of the fixing member 38 is, for example, a male buckle of a side-release buckle, then the retaining-side engaging member 35 is made from a female buckle of a side-release buckle. For example, if the engaging member of the fixing member 38 is, for example, the female buckle, then the retaining-side engaging member 35 is made from the male buckle. Note that the retaining-side engaging member 35 is not limited to the male and female buckles of a side-release buckle; any buckle other than a side-release buckle (for example, a front-release buckle or a cam buckle) that can be detachably connected to the engaging member of the fixing member 38 may be used.

[0047] As shown in Figures 2A and 4, the main body holding portion 36 is the part that holds the main body 21 of the electrocardiogram measuring device 20. The main body holding portion 36 is made of a sheet-like material that has cushioning properties to prevent injury to the skin of the cow U when the device fixing device 30 is attached to the cow U's body. The main body holding portion 36 is fixed to the connecting portion 34 by being wrapped around the connecting portion 34 while holding the main body 21. By being fixed to the connecting portion 34, the main body holding portion 36 covers one end of the holding-side engaging member 35 and the fixing member 38 (the fixing-side engaging member 40 and the belt lock member 42, which will be described later). Therefore, when the device fixing device 30 is attached to the cow U's body, one end of the holding-side engaging member 35 and the fixing member 38 does not directly touch the skin of the cow U, and thus the skin of the cow U is not injured by the holding-side engaging member 35, etc. when the device fixing device 30 is attached.

[0048] The main body holding portion 36 has a storage portion 37 for housing the device body 21. The storage portion 37 is a bag-shaped part capable of housing the device body 21. The storage portion 37 is provided on the inner surface of the main body holding portion 36 when the main body holding portion 36 is wrapped around the connecting portion 34.

[0049] As shown in Figures 2B and 5, the fixing member 38 is a member that fixes the holding member 31 to the body of the cow U. The fixing member 38 is formed, for example, by a pair of belt-shaped members. When the device fixing device 30 is attached to the body of the cow U, one end of the fixing member 38 is connected to one end of the holding member 31, and the other end is connected to the other end of the holding member 31. The fixing member 38 has belt-shaped members connected to each of the bifurcated parts formed at the connecting portion 34. The fixing member 38 fixes the holding member 31 in the appropriate position on the body of the cow U by, for example, adjusting the length of the pair of belt-shaped members connected to the holding member 31.

[0050] In this way, by connecting belt-shaped members to each of the bifurcated connecting parts 34 and adjusting the length of each belt-shaped member, the fit of the device fixing device 30 to the cow U can be improved.

[0051] In the following explanation, the fixing member 38 will be described using one of the belt-shaped members from the pair.

[0052] The fixing member 38 includes a belt member 39, a fixing-side engaging member 40, a length adjustment member 41, and a belt lock member 42.

[0053] The belt member 39 is the main body portion of the fixing member 38. The belt member 39 is made of an expandable material. That is, the fixing member 38 is made of an expandable material. The belt member 39 is made of, for example, an expandable rubber material. By making the belt member 39 of an expandable material, the device fixing device 30 can be stably attached to the cow U regardless of the cow's body shape.

[0054] The fixed-side engaging member 40 is a member for connecting the holding member 31 and the fixed member 38. More specifically, the fixed-side engaging member 40 is a member for connecting the holding member 31 to the holding-side engaging member 35. The fixed-side engaging member 40 is formed from a lightweight, strong material such as resin or carbon fiber. The material of the fixed-side engaging member 40 varies depending on the configuration of the holding-side engaging member 35. Note that the specific example is the same as that of the holding-side engaging member 35, so the explanation is omitted.

[0055] The length adjustment member 41 is a member for adjusting the length of the belt member 39. The length adjustment member 41 is provided in the middle of the belt member 39. The length adjustment member 41 is a known buckle, such as a slider buckle or a ladder lock buckle. The length adjustment member 41 is formed from a lightweight and strong material, such as a resin material or a carbon fiber material.

[0056] The belt lock member 42 is a member for adjusting the length of the belt member 39 and for fixing the belt member 39 at the adjusted length. The belt lock member 42 is a known buckle, such as a cam buckle or a ratchet buckle. The belt lock member 42 is formed from a lightweight and strong material, such as a resin material or a carbon fiber material.

[0057] The fixing member 38 has a belt member 39 that is narrower and thinner than the electrode holding portion 32 and is formed from a long, elongated member. Furthermore, the fixing side engaging member 40, length adjustment member 41, and belt lock member 42 of the fixing member 38 are formed from lightweight and strong materials such as resin or carbon fiber. For this reason, the fixing member 38 is lighter than the holding member 31 including the electrode holding portion 32. In other words, the device fixing device 30 has a holding member 31 including the electrode holding portion 32 that is heavier than the fixing member 38.

[0058] As shown in Figures 2A and 4, the cover member 43 is a member that covers the connection between the holding member 31 and the fixing member 38. More specifically, the cover member 43 is a member that covers the connection between the holding-side engaging member 35 and the fixing-side engaging member 40. As shown in Figure 4, the cover member 43 is made of a sheet-like material that has cushioning properties to prevent injury to the skin of the cow U when the device fixing device 30 is attached to the cow U's body. The cover member 43 is fixed to the connection between the holding-side engaging member 35 and the fixing-side engaging member 40 by being wrapped around the connection. By being fixed to the connection, the cover member 43 covers the holding-side engaging member 35 and the fixing-side engaging member 40. Therefore, when the device fixing device 30 is attached to the cow U's body, the holding-side engaging member 35 and the fixing-side engaging member 40 do not directly touch the skin of the cow U, and thus the holding-side engaging member 35 and the fixing-side engaging member 40 do not injure the skin of the cow U when the device fixing device 30 is attached.

[0059] Next, the method for attaching the device fixing device 30 to the cow U will be described. However, this method of attachment is not limited to the following method.

[0060] As shown in Figure 6, for example, a connecting portion 34 formed on one end of the electrode holding portion 32 (for example, the left end in Figure 6) is connected to one end of the fixing member 38 (for example, the left end in Figure 6). More specifically, a holding-side engaging member 35 of the connecting portion 34 formed on one end of the electrode holding portion 32 is connected to a fixing-side engaging member 40 formed on one end of the fixing member 38.

[0061] Next, the electrode holder 32 is positioned below the upright cow U so that its first surface 32a is in contact with the cow U's chest. At this time, the electrode holder 32 is positioned so that the electrodes 22 (first electrode 22A, second electrode 22B, and third electrode 22C) are located on the left side of the cow U (right side in Figure 6). The electrode holder 32 is also positioned directly behind the cow U's forelegs. In addition, a drying agent or water is applied to the electrodes 22 (first electrode 22A, second electrode 22B, and third electrode 22C) to prevent drying.

[0062] Next, the electrode holder 32 and the fixing member 38 are wrapped around the torso of the cow U so that the electrode holder 32 contacts the cow U's chest. More specifically, the fixing member 38, which is connected to the electrode holder 32 positioned on the chest of the upright cow U, is wrapped along the right side (left side in Figure 6) of the cow U's torso toward the upper spine. Meanwhile, the other end of the electrode holder 32 that is not connected to the fixing member 38 (for example, the right end in Figure 6) is wrapped along the left side (right side in Figure 6) of the cow U's torso.

[0063] Then, the other end (right end in Figure 6) of the fixing member 38, which is wrapped around the spine of the cow U, is connected to the other end of the electrode holding part 32, which is wrapped along the left side of the cow U's torso. More specifically, the holding-side engaging member 35 of the connecting part 34 formed on the other end of the electrode holding part 32 is connected to the fixing-side engaging member 40 formed on the other end of the fixing member 38. As a result, the electrode holding part 32 and the fixing member 38 are wrapped around the cow U.

[0064] Furthermore, the length adjustment member 41 and belt lock member 42 of the fixing member 38 adjust the length of the belt member 39 so that the electrode holder 32 does not slip off the body of the cow U. The belt lock member 42 then holds the belt member 39 at the adjusted length. As a result, the electrode holder 32 and the fixing member 38 are held in a fitted state around the body of the cow U.

[0065] Furthermore, the cover member 43 is wrapped around and secured to one side (left side in Figure 6) of the connection between the connecting portion 34 and the fixing member 38, so as to cover the holding-side engaging member 35 and the fixing-side engaging member 40. Similarly, the main body holding portion 36, which holds the main body 21 of the electrocardiogram measurement device 20, is wrapped around and secured to the other side (right side in Figure 6) of the connection between the connecting portion 34 and the fixing member 38. As a result, the retaining-side engaging member 35, the fixing-side engaging member 40, the length adjustment member 41, and the belt lock member 42 are not exposed to the outside of the device fixing device 30, so that the retaining-side engaging member 35, etc., do not come into contact with the skin of the cow U and injure the skin of the cow U.

[0066] By attaching the device fixing device 30 to the cow U in this manner, the holding member 31 (electrode holding part 34), which is heavier than the fixing member 38, is fixed to the underside of the upright cow U. Therefore, when the holding member 31 is fixed to the body of the cow U by the fixing member 38, the center of gravity of the device fixing device 30 is located on the underside of the cow U. This makes it less likely for the electrodes 22 of the electrocardiogram measuring device 20 to shift due to the movement of the cow U.

[0067] Furthermore, by attaching the device fixing device 30 to the cow U in this manner, the first electrode 22A and the second electrode 22B can be held so that the heart of the cow U is positioned between the horizontal plane H1 and the horizontal plane H2.

[0068] Furthermore, by attaching the device fixing device 30 to the cow U in this manner, the main body holding part 36 that holds the main body of the device 21 is fixed near the shoulder of the cow U, so that the main body of the device 21 will not be crushed by the cow U when the cow U falls over on its side.

[0069] As described above, in the electrocardiogram measurement system 10 and device fixing device 30 of this embodiment, the movement of the cow U makes it less likely for the electrodes 22 of the electrocardiogram measurement device 20 to shift, so that the electrocardiogram of the cow U can be measured stably for a long period of time.

[0070] In this embodiment, the electrocardiogram measurement system 10 and device fixing device 30 are configured with a pair of belt-shaped members, but the invention is not limited to this. For example, the holding member 31 may be formed from a single strip-shaped member, as long as it can be fixed to the body of the cow U.

[0071] Furthermore, in the electrocardiogram measurement system 10 and device fixing device 30 of this embodiment, the weight of the holding member 31 (electrode holding part 32) itself is made heavier than the weight of the fixing member 38, and the holding member 31 (electrode holding part 32) is fixed to the underside of the cow U's body, thereby making the center of gravity of the device fixing device 30 on the underside of the cow. However, the configuration is not limited to this, and the holding member 31 (electrode holding part 32) may be made heavier than the weight of the fixing member 38 by including a weight such as a counterweight.
