Description

[Technical field]

[0001] The present invention relates to a healthcare-related technical field, and more particularly to a cuff cover for use in a vital information measuring device. [Background technology]

[0002] In recent years, it has become common for individuals to measure their own physical and health information (hereinafter referred to as bioinformation) such as blood pressure values ​​and electrocardiogram waveforms on a daily basis using measuring devices and to utilize the measurement results for health management. As a result, there is an increasing demand for devices that emphasize portability, and many portable measuring devices have been proposed, including portable devices that can measure both blood pressure values ​​and electrocardiogram waveforms (for example, Patent Document 1, etc.).

[0003] Patent Document 1 describes a portable cardiovascular testing device equipped with a cuff for measuring blood pressure and electrodes for measuring electrocardiograms. According to this invention, by carrying the device, a user can measure blood pressure and electrocardiogram waveforms at any time.

[0004] Incidentally, in such devices, a cover must be attached to the cuff (air bag) that presses against the human body when measuring blood pressure to prevent it from becoming dirty or deteriorating due to direct contact with the human body; such cuff covers are a known technology (e.g., Patent Document 2).

[0005] The cuff cover must be detachable from the cuff and must be made of a stretchy material such as cloth that does not hinder the expansion and contraction of the cuff; Patent Document 2 also proposes a bag-shaped cuff cover made of such a stretchy cloth material. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2014-36843 A [Patent Document 2] JP 2020-103645 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, in a device capable of measuring both electrocardiogram waveforms and blood pressure values, when a cloth cuff cover such as that disclosed in Patent Document 2 is used, the problem is that the electrocardiogram measurement electrodes placed on the cuff are insulated from the human body to which they are attached, making it impossible to measure the electrocardiogram.

[0008] In view of the above problems, an object of the present invention is to provide a cuff cover suitable for a biological information measuring device equipped with a cuff for measuring blood pressure and electrodes for measuring electrocardiogram. [Means for solving the problem]

[0009] In order to solve the above problems, the cuff cover according to the present invention comprises: A biological information measuring device having a cuff structure including one or more cuffs and one or more electrodes, and a wearing means, the biological information measuring device being worn on a human body by the wearing means to measure a blood pressure value and an electrocardiogram waveform of the human body, the biological information measuring device comprising: a cuff cover for covering the cuff structure, a covering portion formed of a non-conductive material and covering the cuff structure; an attachment means for attaching the covering portion to the cuff structure; The present invention is characterized in that it has an auxiliary current supply means that is provided in the covering portion and that assists electrical current supply between the electrodes of the cuff structure covered by the covering portion and the human body when the bioinformation measuring device is worn on the human body.

[0010] The cuff cover having such a configuration can prevent the cover from insulating the subject's body from the electrodes, which would make it impossible to perform electrocardiogram measurement, and can provide a cuff cover suitable for a bioinformation measuring device capable of measuring both blood pressure and electrocardiogram waveforms. The attachment means includes various means according to the form of the cuff cover, such as an adhesive, double-sided tape, etc., Go A band, hook and loop fastener, snap button, etc. can be used.

[0011] The auxiliary current supply means may be an opening in the covering portion through which the electrode can be exposed. With this configuration, the electrode for electrocardiogram measurement can be brought into direct contact with the human body, so that the electrocardiogram waveform can be measured with high accuracy.

[0012] The current-passing auxiliary means may be a conductive part that covers a portion of the cuff structure, including the electrodes, when the cuff structure is covered with the covering part. The conductive part may be formed by weaving conductive fibers into the covering part, or by covering at least a part of an opening in the covering part with a lid-like member made of a conductive material. With this configuration, the cuff structure can be covered including the electrodes, so that the cuff structure can be protected more reliably and electricity can be passed between the electrodes and the human body via the conductive part.

[0013] The covering part may be formed in a bag shape capable of housing the cuff structure and may include a housing opening that is an opening for housing the cuff structure within the covering part. With such a structure, the cuff structure can be housed within the bag-shaped covering part to cover the entire cuff structure, thereby further improving the protective function for the cuff structure.

[0014] The covering portion is made of a stretchable material, and has an inner covering portion that is in contact with the human body when the cuff structure is housed and in which the current-passing auxiliary means is provided, and an outer covering portion that faces the inner covering portion across the cuff structure when the cuff structure is housed, the accommodation opening is provided in the outer covering portion, is an opening having an area smaller than an area of ​​the cuff structure when the cuff structure is viewed in a plan view, and can be expanded to a size larger than the area of ​​the cuff structure due to the elasticity of the material when accommodating the cuff structure, The attachment means may be the receiving opening in the covering portion.

[0015] With this configuration, there is no need to provide a separate means for attaching the cuff cover; the expandable storage opening provided in the covering portion can be used as an attachment means for the cuff cover, thereby reducing the number of parts in the product.

[0016] The covering portion may include a plurality of the accommodation openings, and a plurality of structures including the cuff structure may be accommodated in the covering portion through the different accommodation openings, and may include a fastening portion for fastening the inner covering portion and the outer covering portion to each other at a location between one accommodation opening and the other accommodation opening. With this configuration, when the cuff structure is accommodated in the covering portion, "floating" of the covering portion near the fastening portion can be prevented, and the electrodes of the cuff structure accommodated in the covering portion and the covering portion can be prevented from being "floated." General Electricity Subsidy means It is possible to prevent misalignment between the

[0017] The present invention can be achieved by combining the above-mentioned configurations together as long as no technical contradiction occurs. Effect of the Invention

[0018] According to the present invention, it is possible to provide a cuff cover that is suitable for a biological information measuring device that is equipped with a cuff for measuring blood pressure and electrodes for measuring electrocardiogram. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] <Example 1> Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, unless otherwise specified, the dimensions, materials, shapes, relative positions, and the like of the components described in the embodiments are not intended to limit the scope of the present invention.

[0021] Fig. 1 is a diagram showing the appearance of cuff cover 1 according to this embodiment, and Figs. 2 and 3 are schematic diagrams showing the appearance of a vital information measuring device 100 in which cuff cover 1 is used. Figs. 4 and 5 are diagrams for explaining the state in which cuff cover 1 is attached to vital information measuring device 100, and Fig. 6 is an explanatory diagram showing the relative positions of the components when vital information measuring device 100 with cuff cover 1 attached is worn on the wrist.

[0022] (Cuff cover configuration) 1A is a schematic plan view showing the appearance of cuff cover 1, and FIG. 1B is a schematic bottom view showing the appearance of cuff cover 1. As shown in FIG. 1, cuff cover 1 according to this embodiment has a substantially rectangular shape with a longitudinal direction, and is a cuff structure (in this embodiment) of biological information measuring device 100 as described later. In the embodiment, the covering portion 10 is formed in a bag shape capable of housing a pressure cuff portion 210 and a sensing cuff portion 220 (described later) therein. The covering portion 10 is formed from a stretchable cloth material, but the method for forming the covering portion 10 is not particularly limited, and the covering portion 10 may be formed by knitting, or multiple cloth materials may be joined together by sewing or heat welding, or the like.

[0023] Here, the elasticity of the covering part 10 is such that it does not interfere with blood pressure measurement (described later) by the bioinformation measuring device 100, and specifically, it has an elasticity that does not hinder the expansion and contraction of the pressure cuff 211 and the sensing cuff 221 described later.

[0024] The covering part 10 includes an inner covering part 10a, which is a side that comes into contact with the wrist of a measurement subject when the vital information measuring device 100 is worn on the wrist of the measurement subject in a state in which the cuff structure is housed, and an outer covering part 10b, which is a side that faces the inner covering part 10a via the cuff structure. Note that in the following description, the side that comes into contact with the wrist when the vital information measuring device 100 is worn on the wrist is referred to as the inner side, and the opposite side is referred to as the outer side.

[0025] The inner covering part 10a is provided with electrode openings 11 and 12 for exposing the electrodes of the cuff structure housed in the covering part as described below. That is, in this embodiment, the electrode openings 11 and 12 correspond to the current-passing auxiliary means. The outer covering part 10b is provided with accommodation openings 21 and 22 for housing the cuff structure inside the covering part 10.

[0026] (Configuration of Biological Information Measurement Device) Fig. 2 is a schematic plan view showing the appearance of vital information measuring device 100 to which cuff cover 1 is attached. Fig. 3A is a schematic view showing the bottom surface of vital information measuring device 100, and Fig. 3B is a schematic view showing the side surface of vital information measuring device 100.

[0027] As shown in Figures 2 and 3, the biological information measuring device 100 is generally configured to have a main body 101, a pressure cuff 210, a sensing cuff 220 (cuff structure), and a belt 400, and can measure blood pressure values ​​and electrocardiogram waveforms while worn on the wrist of a human body. The belt 400 has a first belt 410 having a hook-and-loop fastener 411 with a hook, and a second belt 420 having a belt loop 421. When wearing the biological information measuring device 100, the first belt 410 is wrapped around the wrist and then inserted into the belt loop 421, and the hook-and-loop fastener 411 is inserted into the second belt 420 having a loop with which the hook engages. one Belt section 4 1 Fix it by pasting it at any position on 0.

[0028] (Main body) The main body 101 includes a housing 101a, a display unit 111, an operation unit 112, and a first electrode 140. In addition, although not shown, the main body 101 includes a power supply unit, a control unit, a circuit for electrically connecting with the electrodes described below, a pump for pressurizing air to the cuff, a fluid flow path, an exhaust valve, etc. The power supply may be a battery that supplies the power required to operate the device, and may be, for example, a secondary battery such as a lithium ion battery, or may be a primary battery.

[0029] The control unit also controls the biological information measuring device 100, controls the pump and the like, and performs calculations to measure the blood pressure value and electrocardiogram waveform of the measurement subject based on the information acquired from the cuff structure. The control unit is composed of, for example, a CPU (Central Processing Unit) and may also include a storage device such as a RAM (Random Access Memory).

[0030] The display unit 111 includes a display device such as a liquid crystal display, and may include an LED indicator, etc. The operation unit 112 includes various operation buttons such as a power button, However, the display unit 111 and the operation unit 112 may be integrated into one unit, such as a touch panel display.

[0031] The first electrode 140 is an electrode for measuring the electrocardiogram waveform of the wearer of the biological information measuring device 100, and is electrically connected to the electronic circuit of the main body 101. By bringing the finger or the like of the hand not wearing the biological information measuring device 100 into contact with the first electrode 140, the electrocardiogram waveform can be measured based on the potential difference with the second electrode 223 described later.

[0032] (Cuff structure) One of the cuff structures, the pressure cuff portion 210, is shown in FIG. 3B As shown in FIG. 1, the device is fixed to housing 101a of the main body by fixed part K1, and is configured to include a pressure cuff 211 that compresses the wrist of the attachment part by inflating with air sent from the pump, and a pressure cuff plate 212 that supports pressure cuff 211.

[0033] 3, sensing cuff portion 220, which is the other cuff structure, is fixed by first belt portion 410 and fixing portion K2, and includes sensing cuff 221, back plate 222, second electrode 223, and third electrode 224. Sensing cuff 221 is a fluid bag for detecting the pressure applied to the part compressed by the pressing force of pressure cuff 211, and the pressure applied to the compressed part is measured by detecting the internal pressure of sensing cuff 221 with a small amount of air therein using a pressure gauge (not shown). Back plate 222 is a flexible flat member disposed outside sensing cuff 221, and suppresses excessive bending of sensing cuff 221 when pressure is applied by pressure cuff 211, and equalizes the pressure distribution in sensing cuff 221.

[0034] The second electrode 223 and the third electrode 224 are both electrodes that are arranged at both ends of the short side of the sensing cuff 221 so as to be able to come into contact with the surface of the human body, and the second electrode 223 functions as an electrode for measuring an electrocardiogram waveform, and the third electrode 224 functions as an electrode for removing noise (right leg electrode).

[0035] (Measurement of biological information) Measurement of biological information by biological information measuring device 100 having the above-mentioned configuration is performed as follows. First, main body 101 is oriented toward the back of the hand, pressure cuff 210 is positioned on the back of the wrist and sensing cuff 220 is positioned on the palm of the wrist, and biological information measuring device 100 is fixed to the wrist by belt 400. Specifically, first belt 410 is wrapped around the wrist, passed through belt loop 421 of second belt 420 and then folded back, and hook-and-loop fastener 411 of first belt 410 is fastened to the wrist by belt loop 421 of second belt 420. one Belt section 4 1 0 at any position on the wrist, and wear the biological information measuring device 100 on the wrist.

[0036] Then, the measurement is started by operating the operation unit 112. Specifically, air is injected into the pressure cuff 211, so that the wrist is pressed against the sensing cuff 221 and the wrist (artery) is compressed and occluded. After the blood flow is stopped in this way, air is gradually discharged from the pressure cuff 211 to return the blood flow in the artery, and the pressure at that time is measured by the sensing cuff 221. In other words, blood pressure measurement is performed by the so-called oscillometric method.

[0037] During blood pressure measurement, when the wrist is pressed by the pressure cuff 211, the second electrode 223 and the third electrode 224 are in contact (pressed) with the surface of the wrist. Therefore, by touching the first electrode 140 provided on the housing 101a of the main body 101 with the fingers of the hand not wearing the biological information measurement device 100, it is possible to measure an electrocardiogram waveform by a so-called I-lead method based on the potential difference between the first electrode 140 and the second electrode 223.

[0038] (When the cuff cover is attached) As described above, when measuring biological information using biological information measuring device 100, the cuff comes into contact with the human body, so by attaching cuff cover 1 to the cuff structure, the cuff structure itself is prevented from becoming dirty or deteriorating. Fig. 4A is a schematic diagram showing the bottom surface of biological information measuring device 100 with cuff cover 1 attached to pressure cuff portion 210 and sensing cuff portion 220. 4B is a schematic diagram showing a side view of the vital sign measuring device 100 when the cuff cover 1 is attached. figure Fig. 5A is an explanatory diagram showing cuff cover 1 in a see-through state in the diagram shown in Fig. 4A, and Fig. 5B is an explanatory diagram showing cuff cover 1 in a see-through state in the diagram shown in Fig. 4B. Fig. 6 is an explanatory diagram showing the positional relationship of each component when vital information measuring device 100 with cuff cover 1 attached is worn on wrist T.

[0039] As shown in Fig. 4A, when cuff cover 1 is attached to biological information measuring device 100, second electrode 223 and third electrode 224 are exposed from electrode openings 11 and 12, respectively, and pressure cuff 210 and sensing cuff 220 are covered by covering portion 10. This makes it possible to cover other portions of the cuff structure without impeding contact between second electrode 223 and third electrode 224 and the human body (i.e., without insulating each electrode from the human body), as shown in Fig. 6, and prevents dirt from adhering to the cuff structure.

[0040] Cuff cover 1 is attached to biological information measuring device 100 by accommodating pressure cuff 210 through accommodation opening 21 and sensing cuff 220 through accommodation opening 22 in covering portion 10. The area of ​​accommodation opening 21 when outer covering portion 10b is viewed in plan is smaller than the area of ​​pressure cuff 210 when viewed in plan, and the relationship between accommodation opening 22 and sensing cuff 220 is also the same. For this reason, pressure cuff 21 0、 In order to accommodate the sensing cuff 220 in the covering unit 10 through the accommodation openings 21 and 22, the accommodation openings 21 and 22 are pushed apart with fingers (or the fabric around the accommodation openings is pulled) to expand the accommodation openings 21 and 22, and then the pressure cuff 21 is inserted into the covering unit 10. 0、 It houses the sensing cuff portion 220.

[0041] Since covering portion 10 is made of a material having elasticity, it is possible to expand the opening in this way, and when the force for expanding storage openings 21, 22 is removed, the storage openings attempt to return to their original shape. FIG. 5A shows the layout of each component in a state where cuff cover 1 attached to vital information measuring device 100 is seen through, and storage openings 21 and 22 seen through pressing cuff portion 210 and sensing cuff portion 220 are shown by dashed lines. As shown in FIG. 5A, storage openings 21, 22 in a state restored from the expanded state (i.e., in a normal state) are hooked on the outer ends of pressing cuff portion 210 and sensing cuff portion 220, respectively. That is, cuff cover 1 is attached to vital information measuring device 100 by having storage openings 21, 22 hooked on pressing cuff portion 210 and sensing cuff portion 220, respectively.

[0042] In addition, the cuff cover 1 attached to the bioinformation measuring device 100 in this manner can also be easily removed by expanding the storage openings 21 and 22, which are hooked onto the outer ends of the pressure cuff portion 210 and the sensing cuff portion 220, respectively.

[0043] The cuff cover 1 of this embodiment having the above-mentioned configuration can be easily attached and detached to the cuff structure of a bioinformation measuring device equipped with a cuff for measuring blood pressure and electrodes for measuring electrocardiogram, and does not impede the flow of electricity between the electrodes for measuring electrocardiogram and the human body, making it possible to accurately measure blood pressure values ​​and electrocardiogram waveforms simultaneously.

[0044] (Variation 1) Note that various modifications of cuff cover 1 according to the first embodiment are possible. Such modifications will be described below with reference to the drawings. Fig. 7 is a diagram showing cuff cover 4, which is a first modification of cuff cover 1 according to the first embodiment. Fig. 7A shows cuff cover 4 according to this modification. 7B is a partial plan view of the inner covering portion 10a of cuff cover 4 according to this modification, and FIG. 7B is an explanatory view for explaining conductive fiber portions 41, 42 of cuff cover 4 according to this modification.

[0045] Since cuff cover 4 according to this modification has the same basic configuration as cuff cover 1, such components are given the same reference numerals as in cuff cover 1 and redundant explanations will be omitted. As shown in Fig. 7A, cuff cover 4 according to this modification has conductive fiber portions 41, 42 in place of electrode openings 11, 12 in inner covering-part 10a.

[0046] The conductive fiber portions 41, 42 are woven with conductive fibers (e.g., desired metal fibers) and are provided in positions on the inner covering-part 10a to cover the second electrode 223 and the third electrode 224 when the cuff cover 4 is attached to the vital information measuring device 100, as shown in Fig. 7B. Therefore, when the vital information measuring device 100 with the cuff cover 4 attached is worn on a human body, electricity can be conducted between the human body and the second electrode 223 and the third electrode 224 via the conductive fiber portions 41, 42 of the inner covering-part 10a. In addition, since the conductive fiber portions 41 and 42 are isolated by a non-conductive cloth, the second electrode 223 and the third electrode 224 are not short-circuited.

[0047] With the configuration of this modified example, the sensing cuff portion 220 can be covered including the electrodes, thereby more reliably protecting the cuff structure and enabling electrical current to flow between the electrodes and the human body via the conductive fiber portion.

[0048] (Variation 2) Next, another modified example of the cuff cover will be described. Fig. 8A is a partial plan view of inner covering portion 10a of cuff cover 5 according to this modified example, and Fig. 8B is an explanatory diagram illustrating conductive cap portions 51, 52 of cuff cover 5 according to this modified example.

[0049] Since cuff cover 5 according to this modification has the same basic configuration as cuff cover 1, such components are given the same reference numerals as in cuff cover 1 and redundant explanations will be omitted. As shown in Fig. 8A, cuff cover 5 according to this modification has conductive cap portions 51, 52 in inner covering portion 10a at positions corresponding to electrode openings 11, 12.

[0050] The conductive cap parts 51 and 52 are formed by sealing the openings corresponding to the electrode openings 11 and 12 with a lid-shaped member made of a conductive material (for example, a desired metal). Specifically, for example, the lid-shaped member may be formed by heat welding to the fabric of the peripheral edge of the opening. As shown in FIG. 8B, the conductive cap parts 51 and 52 are provided in the inner covering part 10a at positions that cover the second electrode 223 and the third electrode 224 when the cuff cover 5 is attached to the vital information measuring device 100. Therefore, when the vital information measuring device 100 with the cuff cover 5 attached is worn on the human body, the human body and the second electrode 223 and the third electrode 224 can be electrically connected through the conductive cap parts 51 and 52 of the inner covering part 10a. In addition, since the conductive cap parts 51 and 52 are isolated by the non-conductive fabric, the second electrode 223 and the third electrode 224 are not short-circuited.

[0051] With the configuration of this modified example, the sensing cuff portion 220 can be covered including the electrodes, thereby more reliably protecting the cuff structure and making it possible to electrically connect the electrodes to the human body via the conductive cap portion.

[0052] (Variation 3) Next, still another modified example of the cuff cover will be described. Fig. 9A is a schematic plan view showing the appearance of cuff cover 3 according to this modified example, and Fig. 9B is an explanatory diagram showing the state in which cuff cover 3 according to this modified example is attached to biological information measuring device 100.

[0053] Since cuff cover 3 according to this modification has the same basic configuration as cuff cover 1, such components are given the same reference numerals as in cuff cover 1 and redundant explanations will be omitted. As shown in Fig. 9, cuff cover 3 according to this modification is provided with a fastening portion 31 near the center in the longitudinal direction where inner covering portion 10a and outer covering portion 10b are fastened by, for example, sewing or welding.

[0054] 9B, when the pressing cuff 210 and the sensing cuff 220 are housed in the covering portion 10, such fixing portion 31 can eliminate "floating" of the inner covering portion 10a between the pressing cuff 210 and the sensing cuff 220. This makes it possible to prevent misalignment between the second electrode 223 and the third electrode 224 of the sensing cuff 220 housed in the covering portion 10 and the conductive auxiliary portion of the inner covering portion 10a (the electrode opening, the conductive fiber portion, and the conductive cap portion in each of the above examples).

[0055] <Example 2> In addition to the above, the cuff cover can be in various forms according to the form of the biological information measuring device to which it is attached. Below, other embodiments of the cuff cover according to the present invention will be described with reference to Figs. 10 and 11. Fig. 10A is a schematic plan view showing the appearance of a cuff cover 6 according to this embodiment, and Fig. 10B is a schematic bottom view showing the appearance of the cuff cover 6 according to this embodiment. Fig. 11A is a schematic bottom view showing the appearance of a biological information measuring device 110 in which the cuff cover 6 according to this embodiment is used, and Fig. 11B is a schematic side view showing the appearance of the biological information measuring device 110 in which the cuff cover 6 according to this embodiment is used.

[0056] 10, the cuff cover 6 according to this embodiment has a basic configuration similar to that of the cuff cover 1 according to the first embodiment, and its main component is a bag-shaped covering portion 60 including an inner covering portion 60a and an outer covering portion 60b. Also, like the cuff cover 1, the inner covering portion 60a is provided with electrode openings 61 and 62. On the other hand, the cuff cover 6 according to this embodiment differs from the cuff cover 1 in that the outer covering portion 60b has only one accommodation opening 63.

[0057] 11, in this embodiment, the configuration of the cuff structure of the vital information measuring device 110 to which the cuff cover 6 is attached is different from that of the vital information measuring device 100 of the first embodiment. In the vital information measuring device 110, the configurations of the main body 101, the belt part 400, etc. are the same as those of the vital information measuring device 100, so these components are denoted by the same reference numerals as those of the first embodiment and will not be described again. The vital information measuring device 110 of this embodiment is configured to have only one cuff assembly part 300 as the configuration related to the cuff structure.

[0058] 11, cuff assembly 300 includes curler 310, pressure cuff 320, sensing cuff 330, second electrode 341, third electrode 342, and back plate 350, and these components are stacked together to form an integrated structure. Also, the cuff assembly 300 has a longitudinal direction as a whole, and is fixed to housing 101a of the main body at fixing portion K3. Cuff cover 6 according to this embodiment is used to cover cuff assembly 300.

[0059] Curler 310 is a member having a longitudinal direction that serves as a base for holding pressure cuff 320, and is arranged on the outermost side (the side farthest from the wrist) of cuff assembly 300, as shown in FIG. 11B. Pressure cuff 320 tightens the wrist of the attachment part by expanding with air sent from the pump, and has the role of applying pressure to an artery (not shown) in the wrist. Unlike pressure cuff 211 of biological information measuring device 100, pressure cuff 320 is not arranged only on the back side of the wrist of the wearer, but has a longitudinal direction and is arranged on the palm side of the wrist (i.e., the artery The sensing cuff 330 is configured to extend to the outside of the sensing cuff 330. The functions of the sensing cuff 330, the back plate 350, the second electrode 341, and the third electrode 342 are substantially similar to the corresponding components of the biological information measuring device 100 of the first embodiment, and therefore will not be described.

[0060] When attaching the cuff cover 6 according to this embodiment to the cuff assembly part 300, for example, the longitudinal end of the cuff assembly part 300 on the side where the sensing cuff 330 is located is inserted into the inside of the covering part 60 while pushing and widening the accommodation opening 63 of the cuff cover 6. Then, the cuff assembly part 300 is inserted along the longitudinal direction of the cuff cover 60, and when the longitudinal end on the side where the sensing cuff 330 is located reaches the end inside the covering part 60, the opposite end of the covering part 60 is pulled and hooked toward the other end of the cuff assembly part 300. In this way, the accommodation opening 63 of the outer covering part 10b is restored to an opening smaller than the area when the cuff assembly part 300 is viewed in plan due to the elasticity of the covering part 60, so that the accommodation opening 63 is hooked on the outer end of the cuff assembly part 300. Cuff cover 6 according to this embodiment can be attached to cuff assembly portion 300 in this manner, and can also be easily removed by performing the same procedure in reverse to that used for attachment.

[0061] <Other> The above-mentioned embodiment is merely an illustrative example of the present invention, and the present invention is not limited to the above-mentioned specific embodiment. Various modifications and combinations of the present invention are possible within the scope of the technical concept. For example, the configurations of the conductive auxiliary means of the first and second modifications of the first embodiment can be applied to the second embodiment.

[0062] In addition, although each of the above examples has been described as having a configuration in which the covering portion is formed in a bag shape, the covering portion does not necessarily have to be configured in this manner, and it is also possible for the covering portion to be formed in a sheet shape so as to cover only the inner surface of the cuff structure.

[0063] In addition, the means for attaching the cuff cover is not limited to the storage opening of the bag-shaped covering part, and various means can be used, for example, adhesive, double-sided tape, rubber bands, hook-and-loop fasteners, snap buttons, etc.

[0064] Furthermore, in each of the above examples, the cuff structure is provided with a plurality of electrodes, but the present invention can also be applied to a cuff cover of a vital sign measuring device having a cuff structure with only one electrode.

[0065] In addition, while the above examples have been described as cases in which the vital information measuring device 100 is worn on the wrist, the present invention can also be applied to a cuff cover for a vital information measuring device worn on other parts of the human body, such as the upper arm.
