Description

[Technical Field]

[0001] The present invention relates to a band capable of measuring arterial blood pressure, and more particularly to a band capable of measuring arterial blood pressure by using pads to compress only the radial and ulnar regions of the wrist toward the center of the wrist while simultaneously measuring arterial blood pressure. [Background technology]

[0002] The joints that make up the human arm are the radius and ulna, which form the forearm; eight carpal bones, which form the wrist; five metacarpal joints, which allow for rotation, flexion, and extension, which form the palm; and numerous phalanges, which form the fingers, which enable the ability to grasp objects.

[0003] These joints can be injured through repeated and sustained overuse during movements or activities involving gripping with the hands, and when injured, they can sometimes fail to heal completely and can induce persistent pain.

[0004] Therefore, bands have been devised and used to be worn around the wrist of the body to protect the above-mentioned joints and bones.

[0005] Generally, bands that require protective functions are worn on weak joints of people, along with elbow supporters, ankle supporters, and wrist supporters, to protect these joints, and are worn for safety by athletes playing various sports, workers doing work, or children enjoying play.

[0006] A typical wristband in the prior art is formed in the form of a band that covers the wrist and is configured to compress the entire wrist evenly along the outer surface of the wrist, thereby protecting the wrist joint and preventing excessive bending of the wrist.

[0007] However, such conventional bands only function to simply compress the wrist and do not have any additional health monitoring functions. Of course, recently developed products such as smart bands can collect the user's physical information and monitor their health, but they do not have the function to provide protection by compressing part or the entire wrist.

[0008] Of course, it is possible to combine the technology of previously developed compression bands and smart bands to protect the user's body while collecting physical information, but in reality, such a configuration simply requires collecting information using venous blood.

[0009] [Patent Document 1] Korean Registered Utility Model No. 20-0389554 Summary of the Invention [Problem to be solved by the invention]

[0010] The present invention has been devised to solve the above-mentioned problems of the prior art, and aims to provide a band capable of measuring arterial blood pressure, which can adjust the compression load on the radius and ulna when worn on the user's wrist, and can additionally apply pressure to the radial and ulnar arteries by adjusting the compression load, while simultaneously measuring arterial blood pressure.

[0011] The objects of the present invention are not limited to those mentioned above, and other objects not mentioned herein will be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0012] To achieve the above-mentioned object, according to one aspect of the present invention, a band capable of measuring arterial blood includes a long band unit that covers a user's wrist, at least one compression unit formed on an inner surface of the band unit and configured to compress one of the radial and ulnar regions of the user's wrist toward the center of the wrist, and a measurement unit that is provided on the band unit and measures and collects information about the user's arterial blood when the compression unit applies pressure to the radial and ulnar regions of the user, and the measurement unit is configured to continuously collect information about the arterial blood at a position adjacent to the user's radial artery and ulnar artery.

[0013] In addition, the band unit is formed long and has a constant circumference, and by selectively adjusting the circumference, the compression load of the compression unit on the radial and ulnar regions can be changed, thereby selectively compressing the radial artery and ulnar artery.

[0014] In addition, the band unit can be adjusted to one of a general mode in which the band unit covers the user's wrist with a preset first pressure and maintains contact with the pressure unit, and a measurement mode in which the pressure unit presses the user's wrist with a second pressure relatively greater than the first pressure, at least a portion of which locally presses the user's skin to press parts of the radial artery and ulnar artery.

[0015] In addition, the band unit can be partially bent along its length to overlap twice, allowing the overall circumference to be adjusted.

[0016] Also, the band unit may include a Velcro fastener along a portion of its length, allowing a portion of the double-overlapped portion to be selectively fastened.

[0017] The band unit may include a long strip that covers a portion of the user's wrist, and a connecting body having a certain area, to both ends of which both ends of the strip are rotatably connected, and at least one of the both ends of the strip may be connected or separated by a user's operation.

[0018] The strip may include a first band having a certain length and having the other end connected to one side of the combined body, a second band having a similar shape to the first band and arranged opposite the first band and having the other end connected to the other side of the combined body, and a connecting unit having both ends rotatably connected to one ends of the first band and the second band, respectively, to connect the first band and the second band.

[0019] In addition, insertion guide holes may be formed at both end portions of the combined body so that the other end portions of the first band and the second band may be inserted and combined, respectively, and an operating unit operable by a user may be attached to the center of the combined body, and the operating unit may be configured to adjust the insertion depth of the first band and the second band inserted into the insertion guide holes.

[0020] In addition, a pair of connecting wires may be pierced and coupled to the other ends of the first band and the second band, and each may be connected to the operating unit, and the connecting wires may be pulled by operating the operating unit, so that the first band and the second band are inserted and coupled to the insertion guide hole.

[0021] In addition, the compression unit may include a first compression part that protrudes from the band unit toward the user's wrist and compresses either the radius part or the ulna part, and a second compression part that protrudes from the band unit at a position spaced apart from the first compression part and compresses the other of the radius part and the ulna part, and may be configured not to compress the wrist in areas other than the radius part and the ulna part.

[0022] In addition, the first pressure member and the second pressure member may be formed so that one surface that comes into contact is curved to correspond to the shape of the wrist, and may be formed to have a predetermined length along the length direction of the band unit.

[0023] In addition, one end of the first pressure member and the second pressure member along the length direction is formed to protrude relatively long toward the user's wrist, so that the first pressure member and the second pressure member can press the user's skin and press the radial artery or the superior ulnar artery in the measurement mode.

[0024] The first and second pressure members may be coupled to each other so as to be movable over a predetermined distance in the length direction of the band unit. [Effects of the Invention]

[0025] The band capable of measuring arterial blood pressure according to the present invention, which is intended to solve the above-mentioned problems, has the following advantages.

[0026] First, the present invention is worn on the user's wrist and applies pressure to the radius and ulna through a pressure unit, while simultaneously measuring the user's arterial blood pressure with a separate measurement unit, allowing the user to easily check their health condition.

[0027] Next, when worn on the user's wrist, the device can be adjusted between normal mode and measurement mode to adjust the compression strength on the wrist, and in the measurement mode, the radial artery and ulnar artery are compressed, thereby allowing pre-set information to be collected through arterial blood, which could not be measured in the past. This has the advantage of allowing more accurate information to be collected than the conventional information collection using veins.

[0028] The effects of the present invention are not limited to those mentioned above, and other effects not mentioned above will be clearly understood by those skilled in the art from the claims. [Brief explanation of the drawings]

[0030] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, in which the same components are designated by the same names and reference numerals, and additional description thereof will be omitted.

[0031] In addition, in describing the embodiments of the present invention, the same names and symbols are used for components having the same functions, but it is made clear in advance that they are not substantially completely the same as conventional ones.

[0032] Furthermore, the terms used in the embodiments of the present invention are merely used to describe specific embodiments and are not intended to limit the present invention. The singular expressions include the plural expressions unless otherwise clearly intended in the context.

[0033] Furthermore, in the embodiments of the present invention, the terms "include" or "have" and the like are intended to specify the presence of features, numbers, steps, operations, components, parts, or combinations thereof described in the specification, and should be understood not to preclude the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0034] First Example First, the configuration of a band capable of measuring arterial blood pressure according to a first embodiment of the present invention will be examined in detail with reference to FIGS.

[0035] As shown in the figure, the band capable of measuring arterial blood pressure according to the first embodiment of the present invention is worn on a user's wrist H to stably protect the wrist H without causing side effects such as numbness in the hand, and mainly includes a band unit 100, a pressure unit 200, and a measurement unit 300.

[0036] The band unit 100 is formed long in the shape of a general band and is configured to cover (surround) the user's wrist H. Here, the band unit 100 is formed in a ring shape and at least a portion thereof is detachable and detachable, or a portion thereof is shrunk and shrunk along its periphery, so that it can be worn on the user's wrist H.

[0037] Specifically, the band unit 100 is made of a material such as rubber, fabric, or synthetic resin, and can be separated by removing a portion along the periphery, allowing the user to wear or separate it from the wrist H, as shown in FIG. 2.

[0038] In the present invention, the band unit 100 mainly includes a combined body 120 and a strip 110, and the strip 110 and the combined body 120 are connected together to form a loop in a ring shape. The strip 110 is formed in a single layer or multi-layer state to form a loop shape and is configured to cover the user's wrist H together with the combined body 120. In this case, the combined body 120 may be configured to include a separate loop, and at least one of both ends of the strip 110 in the length direction may be bent and fixed while passing through the loop, thereby allowing the connection state to be released or fixed.

[0039] Here, the band unit 100 includes a separate Velcro (hook and loop fastener) 112 at a portion along the length direction, so that a portion of the double overlapping portion can be selectively fastened.

[0040] In addition, the strip 110 can adjust the overall circumference to fit the user's wrist H by adjusting the length of the overlapping portion that passes through the loop, or the pressure for compressing the user's wrist H can be adjusted.

[0041] In this embodiment, the strip 110 is formed long and has a constant circumference, and by selectively adjusting the circumference, the compression unit 200 (described later) can change the compression load on the radius H1 region and ulna H2 region of the user. The compression load of the compression unit 200 can be adjusted by the strip 110, so that the radial H1 artery and the ulnar H2 artery can be selectively compressed.

[0042] As shown in the figure, the strip 110 is simply formed as a band type and is connected to the connecting body 120, or is configured to pass through a separate loop and be fixed via the Velcro (hook and loop fastener) 112 or the button to cover the user's wrist H.

[0043] Meanwhile, the coupling body 120 is disposed at a position facing the connection unit 130, and both ends of the strip 110 are rotatably coupled to both sides of the coupling body 120, respectively.

[0044] In the present invention, the coupling body 120 has a certain area and both ends of the strip 110 are rotatably coupled to both ends of the coupling body 120, and at least one of the ends of the strip 110 is coupled or separated by a user's operation.

[0045] Specifically, the connecting body 120 is configured to form a loop together with the strip 110 to cover the user's wrist H, and supports the strip 110 so that the circumference can be selectively adjusted.

[0046] In this case, the combined body 120 has a disk or polygonal plate shape, and both ends along the length of the strip 110 are rotatably combined with both ends facing each other along the periphery, and at least one side of the strip 110 is adjusted to cover the wrist H of the user and adjust the circumference.

[0047] In this embodiment, the coupling body 120 is formed in a disk shape, and the loops are formed at both ends thereof, to which both ends of the strip 110 are coupled so as to be rotatable.

[0048] Here, the combined body 120 may be provided with a control means or display means such as a separate board or display inside, and may be provided with an additional battery or the like to record and analyze arterial blood information in conjunction with the measurement unit 300 described below.

[0049] As described above, the band unit 100 according to the present invention includes the strip 110 and the combined body 120 and is configured to cover the user's wrist H. The circumference of the strip 110 can be adjusted to adjust the degree of compression on the user's wrist H.

[0050] Next, the pressure unit 200 is configured to be configured such that at least one pressure unit is provided on each inner surface of the band unit 100, and is capable of compressing either the radius H1 portion or the ulna H2 portion of the user's wrist H toward the center of the wrist H.

[0051] Specifically, the pressure units 200 are configured with at least one on each inner surface of the strip 110 and are arranged to protrude toward the wrist H, and each independently applies pressure to the skin adjacent to the radius H1 and ulna H2 regions of the user's wrist H.

[0052] At this time, the pressure unit 200 is composed of at least one pad, each of which independently protrudes from the inner surface of the strip 110 to apply pressure.

[0053] In this embodiment, the pressure unit 200 includes a first pressure member 210 protruding toward the wrist H and a second pressure member 220 protruding toward the wrist H from the second pressure member, and the first pressure member 210 and the second pressure member 220 are configured to compress the ulna H2 portion and the radius H1 portion, respectively, and not compress the wrist H in other areas. The first pressure member 210 and the second pressure member 220 have a length relatively shorter than the strip 110, and one surface that contacts the wrist H is curved to correspond to the shape of the wrist H, and has a predetermined length along the length direction of the strip 110.

[0054] The length of the strip 110 connected to the connecting body 120 described later can be adjusted to cover the user's wrist H with a first pressure and maintain the contact state of the compression unit 200 in a general mode, or to compress the wrist H with a second pressure relatively higher than the first pressure, so that at least a portion of the compression unit 200 applies strong localized pressure to the user's skin, thereby compressing a portion of the radial H1 artery and the ulnar H2 artery in a measurement mode.

[0055] In this case, the first pressure member 210 and the second pressure member 220 may be arranged symmetrically with the same shape as shown in the figure, and one end portion of each of the first pressure members 210 and the second pressure member 220 may be formed to protrude relatively long along the length direction.

[0056] As such, the compression unit 200 includes the first compression part 210 and the second compression part 220, and can apply compression to the radius H1 region and the ulna H2 region when worn by a user on the wrist H via the strip 110.

[0057] Meanwhile, the measurement unit 300 is provided in at least one of the combined body 120 or the strip 110, and measures the user's arterial blood while the pressure unit 200 applies pressure to the user's radius H1 and ulna H2 regions, thereby collecting preset arterial blood information.

[0058] Specifically, the measurement unit 300 is placed on the strip 110 toward the user's wrist H and selectively measures arterial blood via the user's radial artery H1 and ulnar artery H2 to collect arterial blood information. Here, the measurement unit 300 measures arterial blood in a non-contact manner similar to a commonly disclosed method to collect preset arterial blood information.

[0059] At this time, unlike conventional techniques, the present invention is configured to collect information through arterial blood rather than venous blood, and in the general mode or the measurement mode, the first pressure unit 210 and the second pressure unit 220 pressurize the user's radial artery H1 and ulnar artery H2, respectively, thereby measuring arterial blood.

[0060] In the first embodiment of the present invention, the measurement unit 300 is disposed on the strip 110 at a position adjacent to the radial H1 artery and the ulnar H2 artery, and is configured as a pair to measure the user's arterial blood in a non-contact optical manner toward the user's radial H1 artery and the ulnar H2 artery at a position adjacent to the first pressure member 210 and the second pressure member 220. Here, a plurality of measurement units 300 may be configured, and each may be configured to collect information not only through the radial H1 artery and the ulnar H2 artery but also through other veins.

[0061] As described above, the measurement unit 300 can collect meaningful information from the radial H1 artery and the ulnar H2 artery by changing to the measurement mode while the first pressure unit 210 and the second pressure unit 220 are applying pressure to the radius H1 region and the ulnar H2 region of the user in the normal mode.

[0062] As described above, the band capable of measuring arterial blood pressure according to the present invention includes the band unit 100, the pressurizing unit 200, and the measuring unit 300 and is configured to be wearable on the user's wrist H. The band can be operated in a release mode, a normal mode, or a measurement mode by a user. In the normal mode or the measurement mode, the pressurizing unit 200 measures arterial blood pressure according to the degree to which it presses the radial H1 artery and the ulnar H2 artery, thereby collecting preset information.

[0063] Arteries are generally considered essential for precise examinations because they can collect more accurate information than veins. However, since arteries are located deep inside the skin, it is relatively difficult to apply pressure to them, and in the medical field, doctors, not nurses, are the ones who perform the measurements.

[0064] However, in the case of the band capable of measuring arterial blood pressure according to the present invention, preset information can be collected via the radial H1 artery and the ulnar H2 artery simply by temporarily compressing the user's arteries without any risk.

[0065] That is, by compressing the radial H1 artery and the ulnar H2 artery in the measurement mode, it is possible to collect preset information through arterial blood, which could not be measured with existing devices, and this has the advantage of being able to collect more accurate information than the conventional information collection using veins.

[0066] In the normal mode, the user's arterial blood information is measured, and since continuous measurement is possible, changes in the user's electrocardiogram, blood pressure, etc. can be continuously sensed to collect arterial blood information.

[0067] In this case, the present invention can measure the user's arterial blood and collect information in the general mode or all of the measurement modes. However, since the measurement mode may excessively compress the user's radial H1 artery and ulnar H2 artery, it is preferable to use it only for a short period of time.

[0068] In addition, a separate transmitting / receiving means may be provided within the combined body 120 to collect and simultaneously transmit / receive arterial blood information of the user to the outside, or to manage the user's health condition in real time in conjunction with a specialized institution.

[0069] Next, a modified form of the pressurizing unit 200 according to the first embodiment of the present invention will be discussed in detail with reference to FIG.

[0070] FIG. 4 is a view showing a state in which the lower ends of the first pressure member 210 and the second pressure member 220 are formed to protrude from the band of FIG.

[0071] Looking closely at the drawings, the basic configuration of the compression unit 200 is substantially the same as that of the above-described embodiment, but differs in some configurations of the first compression unit 210 and the second compression unit 220. Specifically, one end of the first compression unit 210 and the second compression unit 220 along the length direction is formed to protrude relatively long toward the user's wrist H, and selectively applies additional compression to the user's wrist H.

[0072] In this embodiment, as shown in FIG. 4(a), the first pressure member 210 and the second pressure member 220 are formed so that their lower ends along the length are pointed and protrude by a certain length, and in the normal mode, they press the radius H1 and ulna H2 regions of the user together with the remaining portions.

[0073] 4(b), in the measurement mode, the length of the strip 110 decreases, and the first and second pressure members 210 and 220 additionally press the radius H1 and ulna H2 regions. At this time, the protruding portions of the first and second pressure members 210 and 220 apply a strong localized pressure to the user's skin at the wrist H region of the user due to an increase in the pressure.

[0074] Here, the protruding portions of the first pressure member 210 and the second pressure member 220 press against a part of the user's skin to press the radial H1 artery and the ulnar H2 artery, thereby compressing the arterial parts that cannot be pressed by simple compression.

[0075] That is, the distal ends of the first pressure member 210 and the second pressure member 220 in the longitudinal direction are formed to protrude, so that the radial H1 artery and the ulnar H2 artery can be pressurized more stably in the measurement mode.

[0076] Next, referring to FIG. 5, the modified form of the band according to the present invention will be considered in detail as follows.

[0077] FIG. 5 is a view showing a state in which the pressure unit 200 of the band of FIG. 1 further includes a separate support member.

[0078] 1. Looking closely at the drawings, it is formed in a similar manner to the above-described embodiment, but the pressure unit 200 further includes a separate support member.

[0079] Specifically, the first pressure member 210 and the second pressure member 220 further include a separate support member formed long in the thickness direction and protruding from the lower end portion along the length direction, and the support member is made of a material having a relatively lower contraction force than the first pressure member 210 and the second pressure member 220.

[0080] In the present invention, the first and second compression members 210 and 220 are formed to protrude from the first and second bands 114 and 116 to compress the radius H1 and ulna H2, respectively, and are configured to compress with a certain level of elasticity so that a portion of them contracts when compressed by the compressive force.

[0081] At this time, when the support member is built into the first pressure member 210 and the second pressure member 220, the contraction in the corresponding area is relatively small, which means that the rigidity is increased by the support member, and the corresponding area can be compressed relatively more when compressing the user's wrist H.

[0082] As a result, the support member according to the present invention is disposed in a protruding form at one end of the first and second compression parts 210 and 220 along the length direction, and thus in the normal mode, it applies pressure to the radius H1 and ulna H2 areas of the user with similar pressure as other areas.

[0083] However, during the measurement mode, the pressure of the first pressure unit 210 and the second pressure unit 220 increases, and accordingly, the portion adjacent to the support member contracts relatively less, and at the same time, the user's skin is locally compressed, pressurizing the radial H1 artery and the ulnar H2 artery.

[0084] That is, the support member is provided at the distal end along the length of the first pressure member 210 and the second pressure member 220, and can apply pressure to the radial H1 artery and the ulnar H2 artery while minimizing contraction of the corresponding area during the measurement mode.

[0085] As described above, the band capable of measuring arterial blood pressure according to the first embodiment of the present invention is examined in detail. By adjusting the length of the strip 110, the degree to which the pressure unit 200 presses the user's wrist H can be adjusted, and at the same time, a part of the pressure unit 200 presses the user's radial artery H1 and ulnar artery H2, thereby stably collecting arterial blood information.

[0086] Second Example Next, a second embodiment of the present invention will be examined in detail.

[0087] The band according to the second embodiment of the present invention is partially similar to the first embodiment, but has a different configuration in the band unit 100.

[0088] First, the configuration of the second embodiment of the present invention will be considered in detail with reference to FIGS. 6 to 9.

[0089] FIG. 6 is a diagram showing a schematic configuration of a band according to a second embodiment of the present invention, and FIG. 7 is a diagram showing the band of FIG. 6 when it is removed from the wrist H. As shown in FIG.

[0090] 8 is a diagram showing the change between the wearing mode and the measurement mode depending on the wearing state of the band of FIG. 6, and FIG. 9 is a diagram showing the internal structure of the operation unit 400 of the band of FIG.

[0091] Looking closely at the drawings, the circumference of the band unit 100 is adjusted to cover the user's wrist H, and the pressurizing unit 200 and the measuring unit 300 are provided on the inner surface. The band unit 100 includes a strip 110 and a connecting body 120, but the configurations of the strip 110 and the connecting body 120 are different from those of the first embodiment.

[0092] Specifically, the strip 110 is connected to the connecting body 120 to form a ring shape, and unlike the first embodiment, a plurality of members are connected continuously along the length direction.

[0093] The strip 110 according to the second embodiment of the present invention mainly includes a first band 114, a second band 116, and a connecting unit 130. The first band 114 has a certain length, and the other end thereof is rotatably connected to the connecting body 120. The second band 116 has a similar shape to the first band 114, is disposed opposite the first band 114, and the other end thereof is rotatably connected to the connecting body 120.

[0094] That is, the first band 114 and the second band 116 each have a predetermined length and are rotatably coupled to both sides of the coupling body 120 so as to cover the user's wrist.

[0095] Here, the first band 114 and the second band 116 are formed with a concave and curved inner surface so as to cover the wrist H, and the compression unit 200 is attached to one side of the inner surface so as to compress the radius H1 portion and the ulna H2 portion of the wrist H toward the center of the wrist H, respectively.

[0096] The connecting unit 130 is one of the components that connect the first band 114 and the second band 116, and both ends are rotatably connected to one end of the first band 114 and one end of the second band 116, respectively, to connect the first band 114 and the second band 116.

[0097] Specifically, the first band 114 and the second band 116 are disposed such that the compression units 200 provided thereon are adjacent to the radius H1 and ulna H2 regions of the wrist H and compress them toward the center of the wrist H. At this time, the connection unit 130 is rotatably connected to one end of the first band 114 and the second band 116, respectively, to maintain the connection state, and is configured to support the radius H1 and ulna H2 regions without separation even when the compression units 200 apply pressure to them by a connection body 120, which will be described later.

[0098] As such, the strip 110 includes the first band 114, the second band 116, and the connecting unit 130, and as shown in the figure, is simply formed as a band type and is connected to the connecting body 120 so that its circumference can be selectively adjusted.

[0099] Meanwhile, the combined body 120 according to the second embodiment of the present invention, unlike the first embodiment described above, includes a separate connecting wire W and an operating part 400 therein to be connected to the strip 110, and is configured to be able to selectively adjust the length when combined with the strip 110.

[0100] Specifically, the combined body 120 is disposed at a position facing the connection unit 130, and the other ends of the first band 114 and the second band 116 are rotatably coupled to both sides of the combined body 120. Here, the combined body 120 is adjusted so that at least one of the first band 114 and the second band 116 is coupled or separated by a user's operation, allowing the user to wear or release the band according to the present invention.

[0101] In the present invention, the combined body 120 is formed on one side so that the first band 114 and the second band 116 can be rotated and simultaneously combined or separated, and at this time, the combined state of the first band 114 and the second band 116 can be adjusted by the user's operation so that the compression load of the first band 114 and the second band 116 on the radius H1 portion and the ulna H2 portion can be adjusted.

[0102] Therefore, in the present invention, the coupling body 120 can be adjusted to any one of a release mode, a normal mode, and a measurement mode by adjusting the coupling length when the first band 114 and the second band 116 are coupled and adjusting the degree to which the first band 114 and the second band 116 press against the user's wrist H.

[0103] Specifically, insertion guide holes 122 are formed on both sides of one end of the combined body 120 so that the other end of the first band 114 can be inserted and coupled to it, and the other end of the second band 116 can be inserted and coupled to it, and an operating unit 400 that can be operated by a user is provided at the center of the combined body 120. The operating unit 400 is formed to adjust the insertion depth of the first band 114 and the second band 116 inserted into the insertion guide holes 122.

[0104] At this time, a separate connecting wire W is pierced and coupled to the other end of the first band 114 and the second band 116, and each is connected to the operating part 400 of the coupling body 120, and the pair of connecting wires W are pulled simultaneously by operating the operating part 400, so that the first band 114 and the second band 116 can be inserted and coupled to the insertion guide hole 122.

[0105] That is, the first band 114 and the second band 116 are independently connected to the connecting wire W, and the other ends of the first band 114 and the second band 116 are adjusted to be inserted into the insertion guide hole 122 by the operating unit 400, and can be adjusted to any one of the release mode, the general mode, and the measurement mode depending on whether or not the band is inserted and the insertion depth.

[0106] With this configuration, by operating the operating unit 400 of the combined body 120 to pull and release the connecting wire W, the combined body 120 can be placed in the release mode in which the first band 114 and the second band 116 are separated from the combined body 120 as shown in FIG. 7. Conversely, by operating the operating unit 400 to pull the connecting wire W, the first band 114 and the second band 116 can be connected to the combined body 120 as shown in FIG. 8.

[0107] This band capable of measuring arterial blood always maintains a ring shape as a whole because the first band 114 and the second band 116 remain connected via the connecting wire W even when they are separated from the connecting body 120. As shown in FIG. 7, in an open state in which the second band 116 is separated from the connecting body 120, the wrist H is positioned in a direction that passes through the internal space of the band, and then the operating unit 400 is operated to pull the connecting wire W, so that the band can be worn on the wrist H as shown in FIG. 6.

[0108] At this time, different types of bands need to be applied depending on the thickness of the user's wrist H. In this case, the first band 114 and the second band 116 are manufactured in the same size, and only the connecting unit 130 is manufactured to have different lengths and then connected, so that the diameter of the internal space of the band capable of measuring arterial blood can be adjusted to different values.

[0109] In addition, the insertion depth of the second band 116 into the insertion guide hole 122 can be adjusted between the general mode and the measurement mode by operating the operation unit 400. Here, in the measurement mode, the compressive load of the first band 114 and the second band 116 on the radius H1 portion and the ulna H2 portion increases relatively, and in the general mode, the first band 114 and the second band 116 are inserted relatively shallowly into the insertion guide hole 122, so that the compressive load on the radius H1 portion and the ulna H2 portion decreases relatively.

[0110] Looking more closely, Figure 8(a) shows the state in which the first band 114 and the second band 116 are coupled to the coupling body 120 in the normal mode, and in this case, they are only partially inserted into the insertion guide hole 122.

[0111] The normal mode is a state in which the first pressure member 210 and the second pressure member 220 apply a first pressure to the wrist H of the user, and is a basic wearing mode.

[0112] FIG. 8(b) shows a state in which the first band 114 and the second band 116 are fully inserted into the insertion guide hole 122 and coupled in the measurement mode, and are fastened to compress the user's wrist H relatively more strongly than in the general mode, so that the first compression part 210 and the second compression part 220 compress the radius H1 part and the ulna H2 part intensively.

[0113] At this time, the measurement mode is a state in which the first pressure unit 210 and the second pressure unit 220 each pressurize the user's wrist H with a second pressure higher than the first pressure, and in the measurement mode, the longitudinal ends of the first pressure unit 210 and the second pressure unit 220 locally pressurize the user's skin to additionally pressurize the radial H1 artery and the ulnar H2 artery, thereby enabling the user's arterial blood to be measured by the measurement unit 300 described later.

[0114] Meanwhile, the operating unit 400 includes a fixed body part 410 that is fixedly connected to the connecting body 120 and has a ratchet gear 411 formed on the inner peripheral surface of its open upper end; a rotating body part 430 that is connected to the fixed body part 410 so as to be able to move up and down, and has a stopper protrusion 431 formed on one side that engages with the ratchet gear 411 so that rotation in one direction is restricted when moving downward, and the engagement between the stopper protrusion 431 and the ratchet gear 411 is released when moving upward; and a dial knob 420 that is connected to the rotating body part 430 so as to move up and down and rotate integrally with the rotating body part 430, and is configured to be operated by a user.

[0115] The connecting wires W, which are connected through the first band 114 and the second band 116, are connected to the rotating body part 430 and wound up simultaneously.

[0116] In the operating unit 400 configured in this manner, when the dial knob 420 is rotated in a first direction while being pressed to move the dial knob 420 downward, the rotating body part 430 rotates together with the dial knob 420, and the connecting wire W is wound around the rotating body part 430.

[0117] As a result, the connecting wire W is pulled toward the coupling body 120, and the first band 114 and the second band 116 are inserted and coupled into the insertion guide holes 122. In this state, the rotation body part 430 is restricted from rotating in the opposite direction because the stopper protrusion 431 engages with the ratchet gear 411 of the fixed body part 410. Therefore, the first band 114 and the second band 116 are continuously inserted deeper into the insertion guide holes 122 by rotating the dial knob 420, and the compressive load on the radius H1 portion and the ulna H2 portion increases and is maintained in this state.

[0118] That is, when the connecting wire W is pulled by a predetermined length via the operating unit 400 to insert the first band 114 and the second band 116 into the insertion guide hole 122 to a certain depth, the user's wrist H is compressed in the normal mode, and when the connecting wire W is further pulled to completely insert the first band 114 and the second band 116 into the insertion guide hole 122, the user's wrist H can be compressed in the measurement mode.

[0119] Conversely, to reduce the compressive load on the radius H1 and ulna H2 regions or to separate the first band 114 and the second band 116 from the combined body 120, the dial knob 420 can be pulled upward to release the engagement between the stopper protrusion 431 of the rotating body portion 430 and the ratchet gear 411 of the fixed body portion 410, and in this state, the first band 114 and the second band 116 can be rotated in a direction to separate them from the combined body 120, or the dial knob 420 can be rotated counterclockwise.

[0120] Meanwhile, the insertion guide hole 122 of the combined body 120 may be formed with a wire guide portion 124 that guides the connection path of the connecting wire W so that the connecting wire W of the first band 114 and the second band 116 is connected to the operating part 400 in a form of being wound around the rotating body part 430.

[0121] The wire guide portion 124 may be formed to guide the connecting wire W passing through the second band 116 to both side edge portions of the insertion guide hole 122 .

[0122] In addition, the fixed body part 410 may be formed with wire guide openings 412 for guiding a passage path of the connecting wire W so that the connecting wire W connected from the first band 114 and the second band 116 can pass through and be wound around the rotating body part 430. The wire guide openings 412 may be formed at positions adjacent to both side edges of the insertion guide hole 122 in a shape corresponding to the wire guide part 124.

[0123] The wire guide portion 124 and the wire guide opening 412 allow the connecting wire W to be maintained in a fixed position along a fixed path, so that when the first band 114 and the second band 116 are connected to or separated from the connecting body 120, the connecting wire W can be stably maintained without problems such as twisting or tangling with each other.

[0124] As described above, in the band unit 100 according to the second embodiment of the present invention, the combined body 120 and the strip 110 are configured in a different form from those in the first embodiment described above, and the circumference of the strip 110 can be adjusted by operating the operating unit 400, thereby adjusting the degree to which the band unit 100 covers and compresses the user's wrist H.

[0125] Next, the compression unit 200 according to the second embodiment of the present invention includes the first compression part 210 and the second compression part 220, similar to the first embodiment described above, and is configured with at least one compression part on the inner surface of the first band 114 and the second band 116, respectively, and is arranged to protrude toward the wrist H.

[0126] At this time, the first and second pressure members 210 and 220 are configured to compress at least one of the radius H1 and ulna H2 of the user in a central direction.

[0127] Here, the first pressure member 210 and the second pressure member 220 may be arranged symmetrically with the same shape as shown in the figure, and one end portion of each of the pressure members along the length direction may be formed to protrude relatively long.

[0128] As such, the compression unit 200 includes the first compression part 210 and the second compression part 220, and can apply compression to the radius H1 region and the ulna H2 region when worn by a user on the wrist H via the strip 110.

[0129] The measurement unit 300 is disposed adjacent to the radius H1 region and the ulna H2 region, similar to the first embodiment described above, and measures and collects arterial blood information while the pressure unit 200 applies pressure to the user's wrist H.

[0130] At this time, as shown in the figure, the measurement unit 300 is composed of at least one of the first band 114 and the second band 116 located adjacent to the radial H1 artery and the ulnar H2 artery, or the connection unit 130, and measures the user's arterial blood in a non-contact optical manner toward the user's radial H1 artery and ulnar H2 artery at a position adjacent to the first pressure unit 210 and the second pressure unit 220.

[0131] As such, the band according to the second embodiment of the present invention is basically similar to the first embodiment described above, but the configuration of the band unit 100 is different, and there are differences in the structure for attaching it to the user's wrist H and the method for adjusting the circumference.

[0132] However, in the band of the second embodiment, similarly to the first embodiment described above, the compression unit 200 compresses the user's wrist H and applies pressure at positions adjacent to the radial H1 artery and the ulnar H2 artery, thereby measuring arterial blood information.

[0133] Next, the configuration for adjusting the position of the pressurizing unit 200 in the band capable of measuring arterial blood pressure according to the second embodiment of the present invention will be described in detail with reference to FIGS. 10 and 11.

[0134] As shown in the figure, the first band 114 and the second band 116 can be movably attached by a certain distance along the length direction, and thereby the positions of the first compression part 210 and the second compression part 220 can be adjusted, and the parts of the radius and ulna H2, which may vary depending on the user, can be accurately compressed.

[0135] Specifically, when the band capable of measuring arterial blood pressure according to the present invention is worn on the wrist H, the first pressure member 210 and the second pressure member 220 are arranged opposite each other to pressurize the radius H1 and ulna H2 areas of the wrist H. However, since the shape of the wrist H and the positions of the radius H1 and ulna H2 may vary slightly from person to person, the first pressure member 210 and the second pressure member 220 may not be able to pressurize the correct points depending on the user.

[0136] Therefore, by allowing the user to move and adjust the position of the first pressure member 210 and the second pressure member 220 as desired, the first pressure member 210 and the second pressure member 220 can be positioned accurately, thereby accurately compressing not only the radius H1 and ulna H2 areas but also the radial H1 artery and ulnar H2 artery.

[0137] In order to move the positions of the first and second pressure members 210 and 220 in this manner, an insertion protrusion 230 that can be inserted into the internal space of the first and second bands 114 and 116 may be formed on the contact surfaces of the first and second pressure members 210 and 220 with the first and second bands 114 and 116.

[0138] In addition, the first band 114 and the second band 116 are formed with a pad accommodating portion 101 so that the insertion protrusion 230 can be accommodated and moved, and a movement guide portion 102 is formed in the internal space of the pad accommodating portion 101 so that the insertion protrusion 230 can move by external force while engaged.

[0139] At this time, openings 103 may be formed on the inner surfaces of the first band 114 and the second band 116 along the length direction so that the insertion protrusions 230 of the first pressure part 210 and the second pressure part 220 may be inserted therein. The insertion protrusions 230 may be inserted into the pad receiving part 101 through the openings 103 and moved in the length direction along the movement guide part 102 disposed inside the pad receiving part 101.

[0140] The edge of the movement guide part 102 may be formed with a concave-convex part, and the insertion protrusion 230 may be configured to be separated and moved by an external force while being engaged with the concave-convex part.

[0141] With this configuration, the user can adjust the position of the first pressure applying portion 210 and the second pressure applying portion 220 by pushing and pulling them along the length while wearing the band capable of measuring arterial blood on the wrist H, thereby enabling accurate compression of the radius H1 and ulna H2 areas.

[0142] As described above, the preferred embodiments of the present invention have been described in detail. It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms other than those described above without departing from the spirit or scope of the present invention. Therefore, the above-described embodiments should be considered as illustrative rather than restrictive. Therefore, the present invention is not limited to the above description, but may be modified within the scope of the appended claims and their equivalents. [Explanation of symbols]
