Description

Technical Field

[0001] This application relates to the technical field of wearable devices, specifically to a wearable device. Background Technology

[0002] With increasing awareness of disease prevention, people are paying more and more attention to their personal health. Taking blood pressure monitoring as an example, more and more people are using wearable devices to conveniently monitor their blood pressure. Currently, common wearable devices generally have an air bladder that inflates to compress the user's blood vessels, thus achieving blood pressure monitoring. However, the pressure generated by the inflated air bladder in most wearable devices is insufficient, resulting in less than ideal blockage of the user's blood vessels and reducing the accuracy of blood pressure measurements. Therefore, improving the pressure exerted by the air bladder on the user's blood vessels has become a major concern for industry professionals. Summary of the Invention

[0003] One embodiment of this application provides a wearable device, the wearable device comprising: a device body and a first airbag; the first airbag comprising: a connecting portion and a bending portion, wherein the connecting portion has a first portion and a second portion respectively connected to opposite sides of the device body, and together with the device body, forming a wearing space; the bending portion is connected to the first portion and configured to fold toward the side of the first portion away from the wearing space in a direction away from the second portion, and is detachably connected to the side of the first portion away from the wearing space; wherein, the bending portion is further configured to fold toward the side of the device body away from the wearing space in a direction close to the second portion, and is detachably connected to the side of the second portion away from the wearing space, so that the connecting portion and the bending portion together form a compression space, and the device body is configured to inflate the connecting portion and the bending portion, so that the connecting portion and the bending portion expand into the compression space.

[0004] The wearable device provided in this application embodiment has a first part and a second part connected to opposite sides of the device body in the connecting part of the first airbag. These parts, together with the device body, form a wearing space. Furthermore, the bent part of the first airbag, after connecting to the first part, can fold away from the second part on the side of the connecting part away from the wearing space. This allows the user to not only wear the wearable device within the wearing space but also use the device body normally. Simultaneously, the bent part can also fold towards the second part on the side of the device body away from the wearing space, forming a pressure space together with the connecting part. This allows the connecting part and the bent part to surround the user's wrist, applying pressure to the entire circumference of the user's wrist when blood pressure needs to be measured, thus enhancing the pressure effect and improving the accuracy of blood pressure measurement by the wearable device.

[0011] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0012] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0013] Please see Figures 1 to 2 , Figure 1 This is a side view of the wearable device 10 provided in the embodiments of this application. Figure 2 yes Figure 1 Another side view of the wearable device 10.

[0014] The wearable device 10 provided in this application embodiment can be a smart bracelet, a smartwatch, or a cuff-type blood pressure measuring device, etc. The following example uses a smartwatch as the wearable device 10 for illustration. Figures 1 to 2 As shown, the wearable device 10 includes a device body 100 and a first airbag 200. The device body 100 can integrate various functional components required by the wearable device 10 to achieve functions such as biometric measurement (e.g., blood pressure), image display, and video calls. The first airbag 200 is connected to the device body 100 and can inflate under the control of the device body 100, compressing the user's wrist to block the arteries in the wrist, allowing the device body 100 to cooperate with the first airbag 200 to perform blood pressure measurement. In this embodiment, when the user needs to measure blood pressure, the first airbag 200 can be positioned around the user's wrist to apply pressure to the entire circumference of the wrist, thereby enhancing the compression effect. When the user does not need to measure blood pressure, the first airbag 200 can fold to avoid the device body 100, allowing more or all of the display surface 110 of the device body 100 to be exposed for normal use by the user.

[0015] In some embodiments, the device body 100 can specifically be the head of a smartwatch, and the device body 100 can integrate functional devices such as a display screen, microphone, speaker, and sensors to realize the functions corresponding to the wearable device 10. Simultaneously, the device body 100 can also be equipped with an air pump, which can inflate the first airbag 200 to control the expansion of the first airbag 200 to compress the user's wrist, thereby enabling blood pressure measurement. Furthermore, the opposite sides of the device body 100 can be connected to the first airbag 200, and together with the first airbag 200, they can form a wearing space 101, allowing the user to wear the wearable device 10 on their wrist through the wearing space 101. In this embodiment, the device body 100 can measure the pressure applied to the user by the first airbag 200 and the user's pulse pressure wave, and calculate the user's blood pressure data based on the measured data to realize the blood pressure measurement function of the wearable device 10. The specific calculation method for the blood pressure data can refer to existing technologies, and will not be elaborated here. Of course, it can also be applied to other blood pressure measurement methods that require compression to measure blood pressure.

[0016] Optionally, the device itself 100 can also establish a communication connection (wired or wireless) with an external device (such as a mobile phone, tablet, or laptop). The device itself 100 can transmit the detected data to the external device for calculation and receive the blood pressure data calculated by the external device for display. Of course, the device itself 100 can also calculate the corresponding blood pressure data itself and transmit the blood pressure data to the external device for display.

[0017] Please combine Figures 1 to 2 See Figures 3 to 5 , Figure 3 yes Figure 1 A top view of the wearable device 10. Figure 4 yes Figure 2 A top view of the wearable device 10. Figure 5 yes Figure 1 Another side view of the wearable device 10.

[0018] The side of the device body 100 facing away from the wearing space 101 can be used to display images, allowing users to view the time, weather, photos, etc., through the device body 100. Figures 3 to 4As shown, the device body 100 has a display surface 110 on the side opposite to the wearing space 101. When the first airbag 200 is positioned around the user's wrist for blood pressure measurement, a portion of the display surface 110 may be outside the coverage area of ​​the first airbag 200, meaning it is not covered by the first airbag 200. This allows the user to view the image displayed on the display surface 110 through the uncovered portion, facilitating use of the device body 100. Conversely, when the first airbag 200 is folded to avoid obstructing the device body 100, the display surface 110 can be partially or completely exposed outside the device body 100 for normal user use.

[0019] For example, the display surface 110 includes a first display surface 111 and a second display surface 112. The first display surface 111 and the second display surface 112 can be joined to form a single plane. When the user wears the device body 100 on their wrist using the wearing space 101, that is, when the device body 100 is being used normally and not for blood pressure measurement, both the first display surface 111 and the second display surface 112 are exposed outside the device body 100 and are not covered by the first airbag 200. They can jointly display images for the user to view. However, when the first airbag 200 surrounds the user's wrist for blood pressure measurement, that is, when the user is taking a blood pressure measurement, the first display surface 111 can be covered by the first airbag 200, while the second display surface 112 is exposed outside the first airbag 200. The second display surface 112 can display the blood pressure data measured by the device body 100, and the user can obtain the blood pressure measurement result by viewing the second display surface 112. With this configuration, when the user does not need to measure blood pressure, the first display surface 111 and the second display surface 112 can be combined to form a complete display surface to jointly display the corresponding image. When the user needs to measure blood pressure, the first display surface 111 is blocked, while the second display surface 112 can independently display the image so that the user can view the measured blood pressure data.

[0020] Furthermore, a second display surface 112 is provided on each of the opposite sides of the first display surface 111, and the two second display surfaces 112 can be symmetrically arranged about the symmetrical fold line of the first display surface 111. The three can also be spliced ​​together to form a plane, that is, to form a complete display surface to jointly display the image. Among them, the second display surfaces 112 on opposite sides can display different blood pressure data. For example, the second display surface 112 on one side can display the diastolic blood pressure data, while the second display surface 112 on the opposite side can display the systolic blood pressure data. At the same time, the first display surface 111 and the second display surface 112 can be spliced ​​together to form a circular surface with a diameter greater than or equal to 42 mm, and the width of the first air bladder 200 can be less than or equal to 26 mm, so that the vertical distance from the farthest point of the second display surface 112 on opposite sides to the first display surface 111 can be at least 8 mm, thereby providing sufficient display area for the second display surface 112 to display blood pressure data.

[0021] Optionally, the two second display surfaces 112 can also be arranged asymmetrically, and the second display surfaces 112 are not limited to being spliced ​​with the first display surface 111; it is sufficient that the first display surface 111 and the second display surface 112 are located in the same plane. Furthermore, the first display surface 111 and the second display surface 112 are not limited to forming a circular surface; they can also be spliced ​​to form a rectangular or elliptical surface. In addition, the design size of the first display surface 111, the second display surface 112, and the first airbag 200 are not limited to the values ​​in the aforementioned embodiments; it is sufficient that the second display surface 112 can be exposed outside the first airbag 200 and can independently display images. This embodiment does not impose any limitations on this.

[0022] In some embodiments, when the first airbag 200 covers the first display surface 111 for blood pressure measurement, a display component may also be provided on the side of the device body 100 to display the measurement results for the user's convenience in viewing the blood pressure measurement results. This arrangement provides the user with another area to view the blood pressure measurement results when the second display surface 112 is not visible, thereby improving user convenience.

[0023] In some embodiments, the device body 100 may further be provided with a detection element 130 for detecting the position of the first airbag 200, so that when the first airbag 200 is positioned around the user's wrist, the second display surface 112 is switched to a working interface for displaying blood pressure measurement, thereby displaying the measured blood pressure data. Figures 1 to 4As shown, the detection element 130 is disposed within the device body 100 and is positioned opposite to the first display surface 111. Specifically, the detection element 130 can be a light sensor, and it can receive light rays entering the device body 100 from the first display surface 111. With this configuration, the detection element 130 can determine the position of the first airbag 200 by whether it receives light, that is, whether the first display surface 111 is blocked by the first airbag 200. This allows the device body 100 to switch the display interface of the second display surface 112 based on the determination result.

[0024] Optionally, in addition to switching the working interface of the second display surface 112 according to the judgment result, the device body 100 can also select to turn the blood pressure measurement function on or off according to the judgment result. That is, when the detection element 130 detects that the first display surface 111 is blocked, the device body 100 can simultaneously turn on the blood pressure detection function to perform blood pressure measurement while switching the working interface of the second display surface 112. Optionally, the detection element 130 is not limited to a light sensor; it can also be other types of sensors, as long as they can achieve a similar effect to the light sensor in the aforementioned embodiment. This embodiment does not limit this.

[0025] Optionally, to reduce the probability of accidental switching of the second display surface 112 and accidental triggering of the blood pressure detection function, the number of detection elements 130 can be multiple, and the orthographic projections of the multiple detection elements 130 on the first display surface 111 can be distributed at different positions. Only when more than a preset number of detection elements 130 detect that the first display surface 111 is blocked will the device body 100 switch the working interface of the second display surface 112 and activate the blood pressure detection function. Simultaneously, considering that the device body 100 may be covered by clothing for extended periods, some of the multiple detection elements 130 can also be positioned opposite the second display surface 112 and receive light incident from the second display surface 112 to detect whether the second display surface 112 is blocked. With this configuration, only when more than a preset number of detection elements 130 positioned opposite the first display surface 111 detect that the first display surface 111 is blocked will the device body 100 switch the working interface of the second display surface 112 and activate the blood pressure detection function.

[0026] Optionally, in addition to using a light sensor, the detection element 130 can also be a Hall sensor, and the first airbag 200 can be provided with a component (such as a magnet) that can be sensed by the Hall sensor. Thus, when the first airbag 200 blocks the first display surface 111, the detection element 130 can detect the change in magnetic field strength, thereby generating a corresponding electrical signal to control the second display surface 112 to switch to the corresponding blood pressure measurement interface. Of course, besides the two types of sensors mentioned above, the detection element 130 can also be other types of sensors, as long as they can detect the position change of the first airbag 200; this embodiment does not limit this.

[0027] The device body 100 may also be equipped with a detection module 140, which can detect biological information (such as heart rate, blood pressure, or blood oxygen) through the side of the device body 100 close to the wearing space 101, in order to cooperate with the first airbag 200 to improve the accuracy of blood pressure measurement by the device body 100. Figures 1 to 2 As shown, the detection module 140 is a PPG module, and it can be located inside the device body 100. It emits detection light from the side of the device body 100 closest to the wearing space 101 into the wearing space 101, and receives detection light reflected back into the device body 100 from the user's wrist. Based on the received detection light, it calculates the user's blood pressure information according to a preset algorithm. Simultaneously, the detection module 140 can also measure other physiological parameters of the user during blood pressure measurement, improving the detection efficiency of the device body 100. This configuration allows for comparison and supplementation of the data measured by the detection module 140 with the data measured by the device body 100 using the first airbag 200, thereby improving the accuracy of blood pressure measurement by the device body 100. Furthermore, by covering the display surface 110 of the device body 100 with the first airbag 200, not only is the compression effect increased to ensure blood pressure measurement accuracy, but the normal operation of the detection module 140 is not hindered.

[0028] Optionally, the detection module 140 may not be limited to a PPG module; it may also be an ECG module. In this case, the detection module 140 can be located on the side of the device body 100 near the wearing space 101 and exposed outside the device body 100, so that the detection module 140 can come into contact with the user's wrist when the user wears the wearable device 10, thereby acquiring the user's bioelectrical signals to realize the heart rate detection function. Of course, the detection module 140 may also include both a PPG module and an ECG module, and this embodiment does not limit this.

[0029] The device body 100 also has a first side 150 and a second side 160 connected to the first airbag 200. For example... Figures 1 to 2As shown, the first side 150 may have an assembly groove 151, and one end of the first airbag 200 may be disposed in the assembly groove 151. The inner wall of the assembly groove 151 may also have an air hole communicating with the air pump inside the device body 100. The first airbag 200 may also be inserted into the air hole to achieve communication between the air pump and the first airbag 200. The second side 160 is provided with a connector 161, and the other end of the first airbag 200 can be connected to the second side 160 through the connector 161, thereby forming the aforementioned wearing space 101 together with the device body 100.

[0030] The first airbag 200 can inflate under the control of the device body 100 and compress the user's wrist to block the artery in the user's wrist. For example... Figures 1 to 2 As shown, the first airbag 200 includes a connecting portion 210 and a bending portion 220. The connecting portion 210 has a first part 201 and a second part 202 respectively connected to opposite sides of the device body 100, and the connecting portion 210 and the device body 100 together form the aforementioned wearing space 101. The bending portion 220 is connected to the first part 201 and folds away from the second part 202 on the side of the first part 201 opposite to the wearing space 101, and is detachably connected to the side of the first part 201 opposite to the wearing space 101. Simultaneously, the bending portion 220 can also fold towards the second part 202 on the side of the device body 100 opposite to the wearing space 101, and is detachably connected to the side of the second part 202 opposite to the wearing space 101, so that the connecting portion 210 and the bending portion 220 together form a compression space 203. In this embodiment, when the connecting part 210 and the bending part 220 together form a compression space 203, the device body 100 can inflate the connecting part 210 and the bending part 220 with an air pump, so that the connecting part 210 and the bending part 220 expand into the compression space 203 to compress the entire circumference of the user's wrist, thereby improving the compression effect of the first airbag 200 and improving the accuracy of blood pressure measurement.

[0031] With the above configuration, the first airbag 200 can have two different states to meet the user's needs under different conditions. Specifically, when the bending portion 220 is folded away from the second portion 202 on the side of the first portion 201 opposite to the wearing space 101, the first airbag 200 can be in its normal state. Figure 1 (As shown). At this time, the first airbag 200 does not need to be inflated, and the bending portion 220 will not affect the use of the device body 100. The user can normally view the image displayed on the display surface 110. When the bending portion 220 is folded towards the side of the device body 100 away from the wearing space 101, closer to the second part 202, the first airbag 200 can be in the measurement state. Figure 2 (As shown). At this time, the bent portion 220 will cover the first display surface 111, and the second display surface 112 will switch to the blood pressure measurement interface under the control of the electrical signal triggered by the detection element 130. The device body 100 simultaneously activates the blood pressure detection function and inflates the connecting portion 210 and the bent portion 220, thereby causing the connecting portion 210 and the bent portion 220 to expand and compress the user's wrist to achieve the blood pressure measurement function. Of course, after the bent portion 220 covers the first display surface 111, the blood pressure detection function can also be activated by the user. This embodiment does not limit this.

[0032] Specifically, the connector 161 can be arranged in a ring shape. The first part 201 can pass through the connector 161 and connect with the bent part 220 after passing through the connector 161. When the bent part 220 is folded on the side of the first part 201 away from the wearing space 101, the first part 201 also cooperates with the bent part 220 to fit onto the connector 161, thereby realizing the connection between the connector 210 and the second side 160. The second part 202 can be provided in the assembly groove 151 to realize the connection between the connector 210 and the first side 150. At the same time, the second part 202 can also be inserted into the air hole to realize the connection between the connector 210 and the air pump in the device body 100. For example, the second part 202 can be provided in the air nozzle so that it can be inserted into the air hole using the air nozzle. In this embodiment, the first part 201, the second part 202, and the bent part 220 can be sequentially connected and communicate with each other, and the first part 201, the second part 202, and the bent part 220 can together constitute the first airbag 200. Of course, in some embodiments, the first airbag 200 may not be limited to including the first part 201, the second part 202, and the bent part 220.

[0033] Optionally, the connector 161 can be a complete annular structure or an annular structure with a notch, and during assembly, the first part 201 can be inserted into the connector 161 through the notch. In addition, there can be a certain gap between the connector 161 and the first part 201 so that gas can pass through the connector 161 when the first airbag 200 is inflated.

[0034] The bent portion 220 is connected to the first portion 201 passing through the connector 161 and folds away from the second portion 202 on the side of the first portion 201 facing away from the wearing space 101. The bent portion 220 is also detachably connected to the side of the first portion 201 facing away from the wearing space 101. For example, the first portion 201 and the bent portion 220 can be detachably connected via Velcro A. Simultaneously, after being detached from the first portion 201, the bent portion 220 can be bent towards the second portion 202 and folded onto the side of the device body 100 facing away from the wearing space 101, i.e., covering the first display surface 111. The bent portion 220 can also be detachably connected to the side of the second portion 202 facing away from the wearing space 101, allowing the first portion 201, the second portion 202, and the bent portion 220 to jointly enclose and form the compression space 203. Similarly, the bent portion 220 and the second portion 202 can also be detachably connected via Velcro A. Alternatively, in addition to Velcro, detachable connections can also be achieved using structures such as metal buckles or pin buckles; this embodiment does not limit this.

[0035] With the above configuration, when the user does not need to measure blood pressure, the user can fold the bending part 220 onto the side of the first part 201 away from the wearing space 101. This allows the first part 201 to be fixedly connected to the connector 161 while the first display surface 111 on the device body 100 can still be used normally. When the user needs to measure blood pressure, the user can fold the bending part 220 onto the side of the device body 100 away from the wearing space 101 and detachably connect the bending part 220 to the second part 202. This allows the first part 201, the second part 202, and the bending part 220 to jointly form a compression space 203, which, after expansion, compresses the entire circumference of the user's wrist, thereby enhancing the compression effect of the first airbag 200.

[0036] Alternatively, in addition to a ring-shaped structure, the connector 161 can also be designed as a columnar structure. For example... Figure 5 As shown, a columnar connector 161 may be provided on the first side 160, and a plurality of positioning holes 204 arranged along the length of the first part 201 may be provided on the first part 201. The connector 161 can be inserted into the positioning hole 204, and the end size of the connector 161 can be larger than the size of the positioning hole 204, so that the connector 161 is not easy to fall out of the positioning hole 204, thereby improving the connection between the first part 201 and the equipment body 100.

[0037] To improve measurement accuracy, the wearable device 10 may also include a second airbag 300. For example... Figures 1 to 2As shown, the second airbag 300 can be disposed on the side of the second part 202 near the wearing space 101, and one end of the second airbag 300 can also be disposed in the mounting groove 151 and connected to the air pump in the device body 100. When the second airbag 300 inflates under the control of the device body 100, it can fit against the user's wrist to measure the pressure on the user's wrist and the user's pulse pressure wave, thereby obtaining the user's blood pressure information. That is, the second airbag 300 is a detection airbag for measuring blood pressure, while the first airbag 200 is a compression airbag for compressing the user's blood vessels. With this configuration, the device body 100 can use the second airbag 300 in conjunction with the first airbag 200 to measure blood pressure, thereby improving the measurement accuracy of the device body 100. The connection method between the second airbag 300 and the air pump is the same as or similar to the connection method between the first airbag 200 and the air pump, and will not be described in detail here.

[0038] Optionally, the first airbag 200 can function as both a compression airbag and a detection airbag, allowing the device body 100 to calculate blood pressure by detecting the pressure within the first airbag 200. In this case, the design of the second airbag 300 can be omitted.

[0039] Optionally, since the artery near the little finger is more deeply embedded and harder to block than the artery near the thumb, when the user wears the wearable device 10, the second airbag 300 preferably covers a portion of the user's wrist near the thumb. This allows for the measurement of the pulse pressure wave of the artery near the thumb after the first airbag 200 blocks it. This configuration improves the measurement accuracy of the second airbag 300 and avoids the problem of the second airbag 300 measuring the pulse pressure wave of the artery near the little finger in the user's wrist, thus affecting the accuracy of blood pressure measurement. Optionally, the design of the second airbag 300 can also be omitted. In this case, the first airbag 200 can not only compress the user's blood vessels but also simultaneously measure the user's blood pressure; this embodiment does not limit this.

[0040] Optionally, to improve the appearance consistency of the wearable device 10, the wearable device 10 may also be provided with a decorative strip that covers the first airbag 200 and the second airbag 300 to conceal and decorate them. To avoid restricting the expansion of the first airbag 200 and the second airbag 300, the decorative strip can be made of a highly elastic fabric strip, allowing it to elastically deform as the first airbag 200 and the second airbag 300 expand. This deformation increases its own accommodating space, reducing the restriction caused by the expansion of the first airbag 200 and the second airbag 300 and improving the accuracy of blood pressure measurement by the wearable device 10. Of course, the decorative strip is not limited to a fabric strip; the choice of material can be adapted according to needs, and this embodiment does not limit this.

[0041] In some embodiments, to facilitate wearing the wearable device 10 by a user, the wearable device 10 may further include a strap 400. For example... Figures 1 to 2 As shown, one end of the strap 400 can be connected to the first side 150 of the device body 100, and the other end of the strap 400 can be connected to the end of the bent portion 220 away from the first portion 201. When the connecting portion 210 and the bent portion 220 together form the compression space 203, the strap 400 can cover the side of the connecting portion 210 and the bent portion 220 away from the compression space 203. It can also pass through the connector 161 with the connecting portion 210 and bend with the bent portion 220. With this configuration, the strap 400 can reinforce the first airbag 200, making it easier for the user to wear the wearable device 10.

[0042] Specifically, the strap 400 may include a first mating portion 410 and a second mating portion 420 that are connected. The first mating portion 410, at one end away from the second mating portion 420, is connected to a first side 150 (e.g., a spring bar). The other end of the first mating portion 410 is connected to a first portion 201 and passes through the connector 161 along with the first portion 201. The first mating portion 410 is also located on the side of the connector 210 facing away from the pressure space 203. The second mating portion 420, at one end away from the first mating portion 410, is connected to the end of the bent portion 220 away from the first portion 201 and is located on the side of the bent portion 220 facing away from the pressure space 203, and can be bent along with the bent portion 220. Furthermore, to facilitate detachable connection of the bent portion 220 after bending, the end of the second mating portion 420 connected to the bent portion 220 may protrude beyond the end of the bent portion 220 in the length direction, forming a protrusion 421. The protrusion 421 may be provided with Velcro A on its opposite sides, either close to or away from the opposite sides of the compression space 203, as described in the previous embodiment, so that the protrusion 421 can be detachably connected by Velcro A after being bent with the bending part 220.

[0043] Furthermore, the strap 400 can be a woven band made of a relatively stiff material (such as fishing line and polypropylene yarn), allowing the strap 400 to support the first airbag 200 and control its inflation direction. Since the first airbag 200 is located on the side of the strap 400 closest to the wearing space 101, when the first airbag 200 inflates, the strap 400 can support it in the direction closest to the strap 400, causing the first airbag 200 to inflate as much as possible into the wearing space 101 to compress the user's wrist. With this configuration, since the strap 400 is located on the outermost side of the wearing space 101, it can also partially shield the first airbag 200, thus protecting it. Optionally, the strap 400 can be omitted. Alternatively, the strap 400 can be part of the first airbag 200.

[0044] The wearable device 10 provided in this application embodiment has a first part 201 and a second part 202 connected to opposite sides of the device body 100 by the connecting part 210 of the first airbag 200, which together with the device body 100 forms a wearing space 101. After the bending part 220 of the first airbag 200 is connected to the first part 201, it can also be folded away from the second part 202 on the side of the connecting part 210 away from the wearing space 101, so that the user can not only wear the wearable device 10 using the wearing space 101, but also use the device body 100 normally. Meanwhile, by setting the bending part 220, it can also be folded towards the direction close to the second part 202 on the side of the device body 100 away from the wearing space 101, and together with the connecting part 210, it forms a compression space 203, so that the connecting part 210 and the bending part 220 can be set around the user's wrist, so as to apply pressure to the entire circumference of the user's wrist when the user needs to measure blood pressure, thereby enhancing the compression effect and improving the accuracy of blood pressure measurement by the wearable device 10.
