Description

Technical Field

[0001] This application relates to the field of blood pressure detection technology, specifically to a wearing structure, wearing components, and electronic device. Background Technology

[0002] Blood pressure watches, due to their smaller size and lighter weight, can be worn by users for extended periods, meeting the need for long-term, real-time blood pressure monitoring. However, different users have different wrist sizes and shapes, which can lead to issues such as the watch being too tight or too loose. Both of these conditions can affect the accuracy of blood pressure measurements. Summary of the Invention

[0003] This application provides a wearing structure, wearing components, and an electronic device. When the wearing structure is applied to the electronic device to measure blood pressure, it can ensure that the blood pressure measurement results of different users have high accuracy.

[0004] In a first aspect, this application provides a wearing structure for measuring blood pressure, comprising:

[0005] A first airbag, comprising a first surface and a second surface disposed opposite to each other, the first airbag being configured to compress a measuring portion through the first surface; and

[0006] The wearable device includes a second airbag located on the side of the first airbag having the second surface; the second airbag is configured to fit the measurement site.

[0007] Secondly, this application also provides a wearing component, including a wearing structure and a connecting structure, wherein the wearing structure is configured to connect to the connecting structure.

[0008] Thirdly, this application also provides an electronic device, which includes a host and a wearable component.

[0009] Fourthly, this application also provides an electronic device for measuring blood pressure, comprising:

[0010] A wearable device, the wearable device including a pressure measuring airbag, the pressure measuring airbag including a first surface and a second surface disposed opposite to each other, the pressure measuring airbag being configured to compress a measuring part through the first surface;

[0011] A connecting structure configured to connect with the wearable device and prevent gas in the pressure-measuring airbag from passing through the connecting structure, wherein the size of the inflatable portion of the pressure-measuring airbag varies with the connection position between the connecting structure and the pressure-measuring airbag;

[0012] A pressure sensor is configured to detect the air pressure value in the pressure-measuring airbag;

[0013] An air nozzle, which is connected to the pressure-measuring airbag and is configured to inflate the pressure-measuring airbag;

The functional components include a processor and an air pump. The processor is connected to the pressure sensor, and the air pump is configured to connect to the air nozzle and inflate the pressure-measuring airbag through the air nozzle.

[0015] When the wearing structure provided in this application is applied to an electronic device for blood pressure measurement, the second airbag can be inflated first to adapt the entire wearer to the size and shape of the measuring area, and then the first airbag can be inflated to compress the measuring area, thereby achieving blood pressure measurement. It is understood that by incorporating the second airbag to fit the measuring area, the problem of inaccurate blood pressure measurement caused by the inability to universally adapt to different users' measuring areas of varying sizes and shapes is overcome. In other words, when the wearing structure provided in this application is applied to an electronic device for blood pressure measurement, it can ensure high accuracy of blood pressure measurement results for different users.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0041] In this document, the reference to "embodiment" or "implementation" means that a specific feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of this application. The appearance of this phrase in various places in 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. Without conflict, the embodiments, implementations, and technical features in this application can be combined with each other.

[0042] This application provides a wearing structure, wearing components, and electronic device, which are described in detail below with reference to embodiments.

[0043] Please refer to Figure 1 The electronic device 100 may be, but is not limited to, wearable devices such as watches and wristbands, and can be applied in fields such as wearable medical devices and daily monitoring devices. The electronic device 100 has a wearing state that constitutes a wearable ring, and the electronic device 100 in the wearing state can be worn on the user's measuring area to detect the user's blood pressure.

[0044] The wearable ring refers to a ring-shaped structure suitable for wearing on a user's body part, such as a wearable ring that can be worn on the user's wrist, ankle, or waist. The shape of the wearable ring can be, but is not limited to, a circular ring, an elliptical ring, etc. The measurement site can be, but is not limited to, the wrist, fingers, or ankle.

[0045] Optionally, when the electronic device 100 is in a wearing state, its curvature is a first curvature amount, such as... Figure 1As shown. The electronic device 100 also has an extended state. When the electronic device 100 is in the extended state, its curvature is a second curvature, such as... Figure 2 As shown. The first curvature is greater than the second curvature. In some embodiments, the second curvature can be zero.

[0046] The electronic device 100 includes a main unit 1 and a wearable component 2. The main unit 1 is an assembly of mechanical components and electronic devices capable of performing one or more functions, used to calculate the user's blood pressure. The main unit 1 may also have other functions, such as display, touch control, camera, and communication functions. The wearable component 2 works in conjunction with the main unit 1 to form a wearable ring, allowing the electronic device 100 to be worn on the user's measurement site.

[0047] Please refer to Figure 3 The wearing component 2 includes a wearing structure 20 and a connecting structure 10, wherein the wearing structure 20 is configured to connect to the connecting structure 10. The connecting structure 10 is connected to the host device 1. The wearing structure 20 is used to wrap around the user's measurement area and sense pulse pressure. The connecting structure 10 is used to connect the wearing structure 20 and the host device 1, so that the electronic device 100 is stably worn on the user's measurement area.

[0048] The wearing structure 20 has a first end D1 and a second end D2. The first end D1 is connected to the end of the host 1 away from the connecting structure 10. The second end D2 is connected to the connecting structure 10. That is, one end of the host 1 is connected to the connecting structure 10, the other end of the host 1 is connected to the first end D1 of the wearing structure 20, and the second end D2 of the wearing structure 20 is indirectly connected to the host 1 through the connecting structure 10, thus forming the aforementioned wearable ring. The wearing structure 20 can obtain blood pressure values ​​by inflating to compress the measuring site.

[0049] Most watches currently available have two straps, one connected to one end of the watch body and the other to the other. When the two straps are connected, they form a wearable loop. In this embodiment, the wearing structure 20 is equivalent to one strap. It is understandable that if there were two wearing structures 20, they would need to be connected to form the loop, inevitably resulting in unevenness at the connection point. This would cause pressure on the user's measuring area during inflation, leading to discomfort. Furthermore, if two wearing structures 20 were used, each would need to be independently inflated and deflated, increasing the complexity of the electronic device 100 and raising manufacturing costs. Therefore, the structure provided in this embodiment reduces the design complexity of the electronic device 100 and lowers costs.

[0050] In related technologies, some blood pressure watches have separate straps and separate air bladders. Generally, the air bladder is located on the inside of the strap and in contact with the measuring part. This design makes the watch's wearing structure thicker, affecting wearing comfort. In some embodiments of this application, the thickness of the wearing structure is reduced and comfort is improved by integrating the air bladder and the strap.

[0051] In some embodiments, the connection between the host 1 and the connection structure 10 can be a detachable connection. Similarly, the connection between the first end D1 of the wearing structure 20 and the host 1 can also be a detachable connection. The detachable connection method can be, but is not limited to, magnetic connection, snap-fit ​​connection, threaded connection, or sliding groove connection. Exemplary examples are provided below.

[0052] Please refer to Figure 4 In one embodiment, the host 1 includes a housing 11 and a first magnetic body 12, the first magnetic body 12 being fixed to the housing 11. The connecting structure 10 includes an annular member 110 and a second magnetic body 160, the second magnetic body 160 being fixed to the annular member 110. The first magnetic body 12 and the second magnetic body 160 can magnetically attract each other, so that the host 1 and the connecting structure 10 form a detachable connection.

[0053] Please refer to Figure 5 In another embodiment, the host 1 includes a housing 11, the outer side of which has a groove X4. The connecting structure 10 includes an annular member 110, which is slidably inserted into the groove X4, and the annular member 110 is conformable to the shape of the groove X4. The groove X4 can be a dovetail groove (e.g.,...). Figure 6 As shown), T-slot (such as) Figure 7 (as shown). It is understandable that the dovetail groove and shaped groove can prevent the annular part 110 from falling off the slide groove X4 in a direction perpendicular to the sliding direction.

[0054] Of course, in some embodiments, the pin at one end of the connecting structure 10 can also be inserted into the slot of the housing 11 via a slot. The housing 11 has a locking member that engages with the pin of the connecting structure 10. The user can press the locking member using a button on the surface of the housing, causing the locking member to move and expose a clearance space, thereby allowing the pin of the connecting structure 10 to be pulled out of the housing 11. The housing 11 also has a spring or other restoring device, which restores the position of the locking member when the user does not press it. When the user inserts the pin, it pushes against the mating part of the locking member, triggering the deformation of the spring, causing the locking member to move and expose the clearance position. When the clearance position on the locking member corresponds to the groove on the pin, the locking member moves based on the action of the spring or other restoring device, causing the mating part to engage with the groove on the pin, thereby locking the connecting structure 10 and the housing 11. Of course, there are other connection methods, which will not be described in detail here.

[0055] In some embodiments, the electronic device 100 is a watch for blood pressure measurement, the wearing structure 20 is a watch strap, the main unit 1 is the watch head, and the connecting structure 10 is configured to fix the connection position with the wearing structure 20 to fit the user's wrist circumference. It is understood that the user can adjust the connection position between the wearing structure 20 and the connecting structure 10 to fit their wrist circumference. It should be noted that the connection position between the wearing structure 20 and the connecting structure 10 can remain unchanged during blood pressure measurement.

[0056] In some embodiments, please refer to Figure 1 and Figure 8 The wearing structure 20 is used for measuring blood pressure. The wearing structure 20 includes a first airbag 210 and a wearing member 220. The first airbag 210 includes a first surface M1 and a second surface M2 disposed opposite to each other. The first airbag 210 is configured to press against the measuring site through the first surface M1. The wearing member 220 includes a second airbag 221 located on the side of the first airbag 210 where the second surface M2 is located. The second airbag 221 is configured to fit the measuring site.

[0057] It is understandable that the second airbag 221 is configured to adapt to the measurement site as follows: the second airbag 221 can be used to compress the first airbag 210, providing pressure to the first airbag 210 and the user's measurement site, and the blood pressure value is calculated by detecting the air pressure value in the first airbag 210. Since the second airbag 221 can apply pressure to the user's measurement site by inflating, the size of the measurement site of different users can be adapted by controlling the degree of inflation of the second airbag 221.

[0058] In some embodiments, the wearing element 220 is the second airbag 221, which means that the second airbag 221 has both compression and wearing functions. Taking a watch as an example, it realizes the integration of the watch strap and the airbag, thereby making the wearing structure simpler and the wearing comfort better.

[0059] For example, the wearing structure 20 is used in conjunction with the host device 1 to measure the user's blood pressure. During blood pressure measurement, the wearing structure 20 wraps around and presses against the measuring site to sense pulse pressure from the measuring site. The host device 1 is used to calculate the user's blood pressure value; the host device 1 will be described in detail in subsequent embodiments.

[0060] The wearing structure 20 includes two airbags: a first airbag 210 and a second airbag 221. From the perspective of the second airbag 221, it has an inner side C1 and an outer side C2 facing away from each other. The first airbag 210 is located on the inner side C1 of the second airbag 221. The inner side C1 refers to the side of the second airbag 221 facing the host device 1 when the electronic device 100 is worn, while the outer side C2 refers to the side of the second airbag 221 facing away from the host device 1. Alternatively, when the electronic device 100 is worn on the user's measurement area, the second airbag 221 faces the measurement area, while the outer side C2 refers to the side of the second airbag 221 facing away from the measurement area. The materials of the first airbag 210 and the second airbag 221 can be, but are not limited to, polyvinyl chloride (PVC) or thermoplastic polyurethanes (TPU).

[0061] Both the first airbag 210 and the second airbag 221 can be inflated and deflated independently. Independent inflation and deflation means that the inflation and deflation of the first airbag 210 and the second airbag 221 do not affect each other. Both the first airbag 210 and the second airbag 221 are inflated during blood pressure measurement. When the first airbag 210 is inflated, it directly contacts the user's measuring area through its first surface M1 to sense the user's pulse pressure. When the second airbag 221 is inflated, it compresses both the first airbag 210 and the user's measuring area. The second airbag 221 can be used to adapt to the size and shape of the measuring area. When the user needs to measure blood pressure, the second airbag 221 and the first airbag 210 can be inflated to further adapt the entire wearing structure 20 to the size and shape of the measuring area. Blood pressure is measured by combining the compression of the artery (e.g., radial artery, ulnar artery) by the first airbag 210 and the compression of the first airbag 210 and the measuring area by the second airbag 221 with a pressure sensor.

[0062] Generally, the size and shape of the measuring sites vary among different users. If the wearing structure 20 cannot fit the measuring site, it may be too tight or too loose, which will affect the accuracy of blood pressure measurement. In this embodiment, the second air bladder 221 in the wearing structure 20 can be inflated to fit the measuring site, thereby overcoming the problem of inaccurate blood pressure measurement caused by the inability to universally adapt to different users' measuring sites of varying sizes and shapes. Therefore, when the wearing structure 20 provided in this application is applied to the electronic device 100 for blood pressure measurement, it can ensure that the blood pressure measurement results of different users have high accuracy.

[0063] In some embodiments, the first airbag 210 and the second airbag 221 may share the airbag wall corresponding to the second surface M2. That is, the first airbag 210 and the second airbag 221 are fixedly connected as one unit, and the sidewall of the second surface M2 is the common sidewall of the first airbag 210 and the second airbag 221. This configuration allows for the use of better materials, thereby reducing production costs and the thickness of the wearing structure.

[0064] In some embodiments, please refer to Figure 8 The wearing structure 20 further includes a mesh layer 222, which includes a first mesh portion 2221. The first mesh portion 2221 covers the side of the second airbag 221 facing the first airbag 210 and is used to attach to the measurement area.

[0065] Understandably, the mesh layer 222 has a mesh structure, which has excellent breathability. The mesh layer 222 can be bonded to the first airbag 210 or the second airbag 221 by hot pressing, adhesive, or other methods. When the wearing structure 20 is worn on the measuring area, the first mesh portion 2221 directly contacts the measuring area. Because the first mesh portion 2221 has a mesh structure, the measuring area is less prone to sweating, resulting in better wearing comfort of the wearing structure 20. It should be noted that the user's measuring area can refer to the part or all of the wrist covered by the wearing structure 20, and not just the area compressed by the first airbag 210, such as the area on the user's wrist where a watch is worn.

[0066] It should be noted that the first mesh portion 2221 is at least partially exposed outside the first airbag 210, so that the first mesh portion 2221 can contact the measuring site. In addition, the first surface M1 is at least partially exposed outside the first mesh portion 2221, so as to ensure that the first surface M1 directly contacts the measuring site during blood pressure measurement, thereby improving the accuracy of the measurement.

[0067] Understandably, to allow the measuring area to breathe, a breathable material is used to wrap the airbag, which then directly contacts the measuring area when worn. However, blood pressure measurement works by sensing pulse pressure through an airbag. If the first airbag 210 (the airbag for blood pressure detection) contacts the skin through the mesh breathable material, the breathable material will absorb some of the pressure before transmitting the remaining pressure to the airbag, leading to inaccurate blood pressure readings. In this application, the first surface M1 is at least partially exposed outside the first mesh portion 2221, allowing the first surface M1 to directly contact the measuring area. During blood pressure measurement, the first airbag 210 can then sense and obtain pulse pressure.

[0068] In some embodiments, please refer to Figure 9Optionally, the first mesh portion 2221 is disposed between the first airbag 210 and the second airbag 221. That is, the first airbag 210, the first mesh portion 2221, and the second airbag 221 are stacked sequentially. With this arrangement, the first surface M1 of the first airbag 210 can directly contact the measurement site, thereby ensuring the accuracy of blood pressure detection.

[0069] In some embodiments, please refer to Figure 10 Optionally, the first mesh portion 2221 is provided with a receiving space X1 adapted to the outer contour shape of the first airbag 210, and the first airbag 210 is disposed within the receiving space X1. The first mesh portion 2221 has an attachment surface M3 facing away from the second airbag 221, and the attachment surface M3 is flush with or protrudes from the first surface M1.

[0070] For example, the receiving space X1 can be a through hole penetrating the first mesh portion 2221, or a groove not penetrating the first mesh portion 2221. The shape of the receiving space X1 matches the outer contour shape of the first airbag 210, so that the shape of the first airbag 210 fits the shape of the first mesh portion 2221. If the contact surface M3 of the first mesh portion 2221 is flush with the first surface M1, it means that there is no depression or protrusion at the flush junction (this mainly refers to the case when not inflated), thus providing the user with good wearing comfort. If the contact surface M3 protrudes from the first surface M1, when the first airbag 210 is not inflated, the user's measuring part can only contact the contact surface M3 and will not contact the first surface M1. This avoids the problem of sweating caused by the measuring part contacting the first surface M1, thus also providing the user with good wearing comfort. Understandably, whether the attachment surface M3 is flush with or protrudes from the first surface M1, when the first airbag 210 is inflated, the first airbag 210 will expand, allowing the first surface M1 to protrude from the attachment surface M3. This enables the user to directly contact the first surface M1, thereby ensuring accurate blood pressure measurement results. It should be noted that... Figure 10 The cross-sectional position shown is... Figure 9 The cross-sections shown are in the same location.

[0071] In some embodiments, please refer to Figure 9Optionally, the mesh layer 222 further includes a second mesh portion 2222, a third mesh portion 2223, and a fourth mesh portion 2224. The first mesh portion 2221, the second mesh portion 2222, the third mesh portion 2223, and the fourth mesh portion 2224 are sequentially connected and together form a receiving space, within which the second airbag 221 is disposed. That is, the third mesh portion 2223 is opposite to and spaced apart from the first mesh portion 2221, and the second mesh portion 2222 is opposite to and spaced apart from the fourth mesh portion 2224. The first mesh portion 2221, the second mesh portion 2222, the third mesh portion 2223, and the fourth mesh portion 2224 surround the second airbag 221, thereby enveloping the second airbag 221 and providing protection for it. Furthermore, compared to a design that uses a strap and a second airbag 221 stacked together, this embodiment reduces the overall thickness of the wearing structure 20, resulting in better wearing comfort. Additionally, the mesh structure wrapping around the airbag provides better protection and adapts to changes in airbag volume, thus limiting airbag inflation. It should be noted that the first mesh portion 2221, the second mesh portion 2222, the third mesh portion 2223, and the fourth mesh portion 2224 can be made of the same or different materials.

[0072] In some embodiments, please combine Figure 9 and Figure 10 Reference Figure 1 Optionally, the length of the first airbag 210 is less than the length of the first mesh portion 2221. In other words, the first mesh portion 2221 is at least partially exposed outside the first airbag 210 in the length direction. This arrangement ensures that the user can contact the first mesh portion 2221 in the length direction of the wearer 220.

[0073] In some embodiments, please refer to Figure 9 and Figure 10 Optionally, the width of the first airbag 210 is smaller than the width of the first mesh portion 2221. In other words, the first mesh portion 2221 is at least partially exposed outside the first airbag 210 in the width direction. This arrangement ensures that the user can contact the first mesh portion 2221 in the width direction of the wearer 220.

[0074] In some embodiments, the mesh layer 222 can deform as the first airbag 210 inflates and deflates. That is, when the second airbag 221 inflates, the mesh layer 222 expands along with the expansion of the second airbag 221, thereby adapting to the measurement area. Optionally, the mesh layer 222 is a porous fabric. Fabrics are breathable, soft, lightweight, and have low material costs.

[0075] In some embodiments, please refer to Figure 11 and Figure 12 The wearable component 220 includes a first segment Q1, a middle segment Q3, and a second segment Q2 connected sequentially. The second segment Q2 is connected to the first airbag 210, and the middle segment Q3 is bendable so that the first segment Q1 and the second segment Q2 are stacked. The first segment Q1 has a first connecting portion 223, and the second segment Q2 has a second connecting portion 224 on the side opposite to the first airbag 210. When the first segment Q1 and the second segment Q2 are stacked, they can be connected through the first connecting portion 223 and the second connecting portion 224.

[0076] For example, the wearable piece 220 can be bent through the middle section Q3, causing the first section Q1 and the second section Q2 to be stacked together. It should be noted that after the middle section Q3 is bent, the first section Q1 is located on the side of the second section Q2 facing away from the first airbag 210. The first section Q1 has a first connecting portion 223, and the second section Q2 has a second connecting portion 224. When the wearable piece 220 is in the bent state, the first connecting portion 223 and the second connecting portion 224 face each other and can be connected. The connection between the first connecting portion 223 and the second connecting portion 224 is a detachable connection. The detachable connection can be, but is not limited to, a Velcro connection or a magnetic connection.

[0077] Hook and loop fasteners, also known as Velcro or snap fasteners, consist of a female and a female fastener. The female fastener is made of fine, soft, round fibers (LOOP), while the female fastener is made of stiffer, hooked fibers (HOOK). In one embodiment, the first connecting portion 223 is the female fastener, and the second connecting portion 224 is the female fastener. In another embodiment, the first connecting portion 223 is the female fastener, and the second connecting portion 224 is the female fastener.

[0078] The magnetic connection refers to the first connecting part 223 and the second connecting part 224 being connected together by magnetic attraction. Specifically, both the first connecting part 223 and the second connecting part 224 are magnetic components, and when the wearable piece 220 is in a bent state, the polarities of the first connecting part 223 and the second connecting part 224 are opposite, thus allowing them to attract each other. The magnetic component refers to a magnetic body containing magnetic material, such as a magnet.

[0079] In some embodiments, please refer to Figure 11 The wearable component 220 includes a first segment Q1, a middle segment Q3, and a second segment Q2 connected in sequence. The second segment Q2 is connected to the first airbag 210. The middle segment Q3 is bendable so that the first segment Q1 and the second segment Q2 are stacked.

[0080] For example, the wearable component 220 can be bent, with the bending point being the middle section Q3. After bending, the first section Q1 and the second section Q2 are stacked together. After the middle section Q3 is bent, the first section Q1 is located on the side of the second section Q2 away from the first airbag 210. The second section Q2 is used together with the main unit 1 to form a wearable ring around the measurement site, thereby enabling the first airbag 210 connected to the second section Q2 to sense the user's blood pressure.

[0081] Optionally, the lengths of the first segment Q1 and the second segment Q2 can be changed. When the length of the first segment Q1 increases, the length of the second segment Q2 decreases, and vice versa. In other words, the lengths of the first segment Q1 and the second segment Q2 can be adjusted by changing the position of the intermediate segment Q3, or the lengths of the first segment Q1 and the second segment Q2 can be adjusted by changing their connection position with the connecting structure 10.

[0082] The second airbag 221 can be implemented in the following three forms, and of course, it can also be in other forms.

[0083] In the first implementation method, please refer to Figure 13 The second airbag 221 includes a first sub-bag 2211 and a second sub-bag 2212 connected together. The first sub-bag 2211 is located in the first segment Q1, and the second sub-bag 2212 is located in the second segment Q2. That is, the second airbag 221 is simultaneously disposed in the first segment Q1 and the second segment Q2, and the first sub-bag 2211 in the first segment Q1 and the second sub-bag 2212 in the second segment Q2 are interconnected in their natural state. Here, the so-called natural state means that the second airbag 221 is not affected by external objects. It should be noted that in other embodiments of this application, the structural form of the first embodiment can be used as an example for explanation. In the second embodiment, please refer to... Figure 13 The second airbag 221 includes a first sub-bag 2211 and a second sub-bag 2212 that are connected but not connected. The first sub-bag 2211 is located in the first segment Q1, and the second sub-bag 2212 is located in the second segment Q2. That is, the second airbag 221 is simultaneously located in the first segment Q1 and the second segment Q2, and the first sub-bag 2211 located in the first segment Q1 and the second sub-bag 2212 located in the second segment Q2 are not connected to each other in their natural state.

[0084] In the third embodiment, the second airbag 221 is entirely located within the second segment Q2, and the mesh layer 222 is partially located in the first segment Q1 and partially located in the second segment Q2. That is, the second airbag 221 is only located within the second segment Q2.

[0085] In some embodiments, please refer to Figure 11 , Figure 13 and Figure 14 The wearable device 220 includes a first segment Q1, a middle segment Q3, and a second segment Q2 connected in sequence. The second segment Q2 is connected to the first airbag 210. The middle segment Q3 is bendable so that the first segment Q1 and the second segment Q2 are stacked. The second airbag 221 includes a first sub-bag 2211 and a second sub-bag 2212 connected in communication. The first sub-bag 2211 is located in the first segment Q1, and the second sub-bag 2212 is located in the second segment Q2. The connecting structure 10 is connected to the middle segment Q3. The connecting structure 10 is configured to prevent gas in the second sub-bag 2212 located in the second segment Q2 from filling the first sub-bag 2211 located in the first segment Q1, and the connection position between the second airbag 221 and the connecting structure 10 does not change during blood pressure measurement.

[0086] The connecting structure 10 is located in the middle section Q3, and it is used to compress the middle section Q3, thereby separating the first sub-bag 2211 and the second sub-bag 2212. When the second airbag 221 is inflated, gas enters the second sub-bag 2212. Because the first sub-bag 2211 and the second sub-bag 2212 are separated by the connecting structure 10, the gas in the second sub-bag 2212 cannot enter the first sub-bag 2211. That is to say, only the second section Q2, which is in contact with the user's measurement area, is inflated, while the first section Q1, which is not in contact with the user, is not inflated. This reduces the inflation time and prevents the first section Q1 from increasing in volume due to inflation.

[0087] In some embodiments, the lengths of the first segment Q1 and the second segment Q2 can be changed. When the length of the first segment Q1 increases (the length of the first sub-sac 2211 increases accordingly), the length of the second segment Q2 decreases (the length of the second sub-sac 2212 decreases accordingly), and vice versa. In other words, the lengths of the first segment Q1 and the second segment Q2 can be adjusted by changing the position of the intermediate segment Q3. Simultaneously, the length of the second sub-sac 2212 changes accordingly with the change in the length of the second segment Q2, thereby ensuring that the second segment Q2 can always effectively adapt to the measurement site.

[0088] In some embodiments, please refer to Figure 15The connecting structure 10 includes an annular member 110, which has a through hole X2. The through hole X2 penetrates the annular member 110, i.e., the through hole X2 is a through hole on the annular member 110. The wearing member 220 is configured to pass through the through hole X2, and the wearing member 220 is movable along the through direction of the through hole X2.

[0089] In some embodiments, the annular member 110 is connected to the host 1, and the connection can be detachable or non-detachable. The through-hole X2 on the annular member 110 is a through hole, thus the annular member 110 has an annular structure. When a user wears the electronic device 100, the wearing member 220 passes through the through-hole X2 on the annular member 110. The portion through which the wearing member 220 passes is the first segment Q1, the portion not passed through is the second segment Q2, and the middle segment Q3 is at least partially within the through-hole X2. The user can adjust the size of the wearable ring by pulling on the first segment Q1 or the second segment Q2, thereby further adapting it to measurement sites of different sizes.

[0090] In some embodiments, please refer to Figure 16 The connecting structure 10 further includes an abutment 120, which is at least partially located within the through hole X2. The abutment 120 is configured to cooperate with the annular member 110 to jointly compress the wearable member 220 located within the through hole X2, thereby preventing gas in the second airbag 221 from passing through the abutment 120.

[0091] In some embodiments, the abutment 120 and the annular member 110 abut against opposite sides of the second airbag 221, thereby creating a compression effect on the second airbag 221. Although the first sub-bag 2211 and the second sub-bag 2212 are connected in their natural state, the combined compression action of the abutment 120 and the annular member 110 prevents the gas in the second sub-bag 2212 from entering the first sub-bag 2211.

[0092] In some embodiments, please refer to Figure 17Optionally, the connecting structure 10 further includes an elastic element 130, with its opposite ends elastically abutting against the abutting member 120 and the annular member 110, respectively, so that the abutting member 120 can move along the elastic abutting direction of the elastic element 130. The elastic element 130 can be a spring, or an elastic material such as rubber or silicone. It is understood that the user can adjust the size of the wearable ring by applying a pulling force to the first segment Q1 or the second segment Q2, thereby adapting it to the size of the measuring part. During this adjustment process, the wearing member 220 applies a force to the abutting member 120 in a first preset direction, which is the direction from the abutting member 120 towards the elastic element 130. Because the elastic element 130 is elastic, it will be further compressed, while the abutting member 120 will move in the first preset direction. After the abutment 120 moves in the first preset direction, the abutment force on the wearing member 220 weakens, allowing the user to easily adjust the size of the wearable ring. When the user stops applying tension to the wearing member 220, the elastic member 130 automatically extends, causing the abutment 120 to move in the second preset direction, thus strengthening the abutment force on the wearing member 220. The second preset direction is the opposite of the first preset direction.

[0093] In some embodiments, please combine Figure 15 Reference Figure 17 The annular component 110 includes a first side segment 111, a second side segment 112, a third side segment 113, and a fourth side segment 114, which are bent and connected in sequence. The first side segment 111 and the third side segment 113 are opposite to each other and spaced apart, while the second side segment 112 and the fourth side segment 114 are opposite to each other and spaced apart. The host device 1 is connected to the first side segment 111. The opposite ends of the elastic component 130 elastically abut against the third side segment 113 and the abutment component 120, respectively. The wearing component 220 is inserted between the first side segment 111 and the abutment component 120, and the first side segment 111 and the abutment component 120 together abut against the wearing component 220. When the user applies a pulling force to the first section Q1 or the second section Q2, the abutment component 120 moves in a first preset direction (i.e., the direction from the first side segment 111 towards the third side segment 113), increasing the distance between the first side segment 111 and the abutment component 120, allowing the user to easily adjust the size of the wearable ring. When the user stops applying tension to the wearer 220, the elastic member 130 extends and drives the abutment member 120 to move in the second preset direction (i.e., the direction from the third side segment 113 toward the first side segment 111). The distance between the first side segment 111 and the abutment member 120 decreases, and the two then clamp the wearer 220 together.

[0094] In other embodiments (not shown), the annular component 110 includes a first side segment 111, a second side segment 112, a third side segment 113, and a fourth side segment 114 that are bent and connected in sequence, wherein the first side segment 111 and the third side segment 113 are opposite to each other and spaced apart. The host 1 is connected to the first side segment 111. The opposite ends of the elastic component 130 elastically abut against the first side segment 111 and the abutment component 120, respectively. The wearing component 220 is inserted between the third side segment 113 and the abutment component 120, and the third side segment 113 and the abutment component 120 abut against the wearing component 220 together. When the user applies a pulling force to the first segment Q1 or to the second segment Q2, the abutment component 120 moves in a first preset direction (i.e., the direction in which the third side segment 113 faces the first side segment 111), and the distance between the third side segment 113 and the abutment component 120 increases, so that the user can easily adjust the size of the wearable ring. When the user stops applying tension to the wearer 220, the elastic member 130 extends and drives the abutment member 120 to move in the second preset direction (i.e., the direction from the first side segment 111 to the third side segment 113). The distance between the third side segment 113 and the abutment member 120 decreases, and the two then clamp the wearer 220 together.

[0095] In some embodiments, please refer to Figure 17 The annular member 110 has a receiving cavity X3 communicating with the through hole X2. The abutting member 120 includes an abutting portion 121 and a limiting portion 122 connected together. The limiting portion 122 is disposed within and confined within the receiving cavity X3. The abutting portion 121 is connected to the limiting portion 122 and is used to abut the wearing member 220. Specifically, the receiving cavity X3 has an opening and is connected to the through hole X2 through the opening. The limiting portion 122 is disposed within the receiving cavity X3 and its size is larger than the size of the opening, so that the limiting portion 122 is always constrained within the receiving cavity X3, thereby ensuring that the abutting member 120 will not fall off the annular member 110.

[0096] Optionally, the abutment 120 is at least partially made of an elastic material, and the elastic portion elastically abuts against the wearable member 220. The elastic material can be, but is not limited to, rubber, silicone, etc. In this embodiment, although the abutment 120 cannot move as a whole, it can undergo elastic deformation (compression or elongation), thereby achieving the same effect as the movement of the abutment 120 in the first or second preset direction as described in the previous embodiments. Please refer to the preceding embodiments for details, which will not be elaborated here. It should be noted that in this embodiment, the abutment 120 can be made entirely of an elastic material, or only partially of an elastic material. For example, in one embodiment, the abutment 120 includes an elastic portion and a rigid portion, wherein the elastic portion is elastic and elastically abuts against the wearable member 220, one end of the rigid portion is connected to the end of the elastic portion away from the wearable member 220, and the other end of the rigid portion is connected to the annular member 110. In another embodiment, the abutment 120 includes an elastic portion and a rigid portion, wherein the elastic portion is elastic and elastically abuts against the wearer 220, the rigid portion is connected to the annular member 110, and the elastic portion is sleeved on the outer periphery of the rigid portion.

[0097] In some embodiments, please combine Figure 15 Reference Figure 18 The connecting structure 10 further includes a first rotating member 140 and a second rotating member 150, at least partially disposed within the through hole X2. The first rotating member 140 and the second rotating member 150 are spaced apart and rotatably connected to the annular member 110. The wearing member 220 passes between the first rotating member 140 and the second rotating member 150, such that the first rotating member 140 and the second rotating member 150 respectively abut against opposite sides of the wearing member 220. The first rotating member 140 and the second rotating member 150 are configured to prevent gas in the second airbag 221 from passing through the abutment member 120.

[0098] For example, the first rotating member 140 and the second rotating member 150 are positioned opposite each other and spaced apart to form a gap. The wearing member 220 is located in the gap, so that the first rotating member 140 and the second rotating member 150 abut against opposite sides of the middle section Q3, thereby creating a squeezing effect on the second airbag 221, preventing the gas in the second sub-bag 2212 from entering the first sub-bag 2211.

[0099] The annular component 110 includes a first side segment 111, a second side segment 112, a third side segment 113, and a fourth side segment 114, which are bent and connected in sequence. The first side segment 111 and the third side segment 113 are opposite to each other and spaced apart, while the second side segment 112 and the fourth side segment 114 are opposite to each other and spaced apart. The main unit 1 is connected to the first side segment 111. The opposite ends of the first rotating component 140 are rotatably connected to the second side segment 112 and the fourth side segment 114, respectively. Similarly, the opposite ends of the second rotating component 150 are rotatably connected to the second side segment 112 and the fourth side segment 114, respectively.

[0100] Because the first rotating member 140 and the second rotating member 150 exert a squeezing effect on the wearing member 220, when the wearing member 220 moves, it will drive the first rotating member 140 and the second rotating member 150 to rotate. Therefore, the user can adjust the size of the wearable ring by applying a pulling force to the first segment Q1 or the second segment Q2. Compared to the wearing member 220 sliding on the surfaces of the first rotating member 140 and the second rotating member 150, making the first rotating member 140 and the second rotating member 150 rotatable reduces the pulling force required for the user to pull the wearing member 220, thus requiring less effort from the user.

[0101] When the user pulls the wearing component 220, if the length of the first segment Q1 decreases, the first rotating component 140 rotates in the first direction, and the second rotating component 150 rotates in the second direction. If the length of the first segment Q1 increases, the first rotating component 140 rotates in the second direction, and the second rotating component 150 rotates in the first direction. The first and second directions are opposite.

[0102] Optionally, in any of the above embodiments, the connecting structure 10 and the host 1 are detachably connected. It is understood that by making the connecting structure 10 and the host 1 detachably connected, when the user needs to remove the electronic device 100 from the measuring area, the connecting structure 10 can be directly detached from the host 1. The user can then directly reconnect the connecting structure 10 to the host 1 the next time they wear it. This process does not require adjustment of the lengths of the first segment Q1 and the second segment Q2, thus reducing the user's wearing time. Conversely, if the connecting structure 10 and the host 1 were not detachably connected, then when the user removes the electronic device 100 from the measuring area, the lengths of the first segment Q1 and the second segment Q2 of the wearing piece 220 need to be adjusted, and the lengths of the first segment Q1 and the second segment Q2 need to be adjusted again the next time they wear it, which wastes the user's time. Therefore, in this embodiment, the connection structure 10 and the host 1 are set to be detachably connected. For the same user, after the length of the first segment Q1 and the second segment Q2 of the wearing piece 220 is adjusted to a suitable size, it does not need to be adjusted again, which greatly saves the user's time.

[0103] In some embodiments, please refer to Figure 19 and Figure 20 The main unit 1 further includes an air pump 13, a first pressure sensor 14, and a second pressure sensor 15. The air pump 13 is used to inflate and deflate the first airbag 210 and the second airbag 221. The first pressure sensor 14 is connected to the first airbag 210 and is used to detect the air pressure inside the first airbag 210. The second pressure sensor 15 is connected to the second airbag 221 and is used to detect the air pressure inside the second airbag 221.

[0104] The first airbag 210 includes a first air nozzle 211, and the second airbag 221 includes a second air nozzle 2213. The first airbag 210 is used for inflation and deflation through the first air nozzle 211, and the second airbag 221 is used for inflation and deflation through the second air nozzle 2213. One end of the first air nozzle 211 is connected to the internal space of the first airbag 210, and the other end is connected to an air pump 13, which inflates the internal space of the first airbag 210 through the first air nozzle 211. Similarly, one end of the second air nozzle 2213 is connected to the internal space of the second airbag 221, and the other end is connected to the air pump 13, which inflates the internal space of the second airbag 221 through the second air nozzle 2213.

[0105] The host unit 1 may also include a processor 16, with an air pump 13, a first pressure sensor 14, and a second pressure sensor 15 all electrically connected to the processor 16. Optionally, the processor 16 first controls the air pump 13 to inflate the second airbag 221 so that the wearable device 220 fits the user's measurement site. The second pressure sensor 15 feeds back the air pressure information inside the second airbag 221 to the processor 16 in real time. When the air pressure in the second airbag 221 reaches a preset pressure, the processor 16 then controls the air pump 13 to inflate the first airbag 210 so that the first airbag 210 compresses the blood vessels at the measurement site, and the first pressure sensor 14 feeds back the air pressure information inside the first airbag 210 to the processor 16 in real time. It can be understood that when the first airbag 210 compresses the blood vessel, the pulsating pressure of the blood vessel will be transmitted to the first airbag 210. Therefore, the air pressure information obtained by the first pressure sensor 14 is related to blood pressure. After analyzing the received pressure signal inside the first airbag 210, the processor 16 can obtain the user's blood pressure information.

[0106] In some embodiments, blood pressure measurement is performed using the oscillometric method. For example, the second airbag 221 is first inflated to fit the measurement site. After the second airbag 221 is fully inflated, the first airbag 210 is inflated to compress the blood vessel at the measurement site. The first airbag 210 is inflated until the blood vessel is blocked, at which point the pulsating pressure of the blood vessel is zero. Then, the gas in the first airbag 210 is released at a preset rate. During the deflation process, the pulsating pressure when the blood vessel begins to pulsate again is the systolic pressure, and the pulsating pressure when the pulsation of the blood vessel suddenly weakens or disappears is the diastolic pressure.

[0107] Please refer to Figure 14 and Figure 19 The host unit 1 may also include a display screen 17 electrically connected to the processor 16, the display screen 17 being mounted on the housing 11. The display screen 17 can be used to display relevant information to the user. For example, the processor 16 controls the display screen 17 to display blood pressure measurement results. The display screen 17 can be a touchscreen, allowing the user to input relevant operations. For example, after the user clicks the application icon for blood pressure measurement displayed on the display screen 17, the processor 16 controls the air pump 13 to inflate the first airbag 210 and the second airbag 221 to begin blood pressure measurement.

[0108] Please refer to Figures 21 to 23 In some embodiments, an electronic device 100 is provided for measuring blood pressure, including a wearable device 220, the wearable device 220 including a pressure measuring airbag 225, the pressure measuring airbag 225 including a first surface M1 and a second surface M2 disposed opposite to each other, the pressure measuring airbag 225 being configured to compress the measuring site through the first surface M1.

[0109] The connecting structure 10 is configured to connect with the wearable device 220 and prevent gas in the pressure measuring airbag 225 from passing through the connecting structure 10. The size of the inflatable portion in the pressure measuring airbag 225 varies with the connection position between the connecting structure 10 and the pressure measuring airbag 225.

[0110] Pressure sensor 18 is configured to detect the air pressure value in pressure-measuring airbag 225.

[0111] Air nozzle 2251 is connected to pressure-measuring airbag 225 and is configured to inflate pressure-measuring airbag 225.

[0112] The main unit 1 includes a housing 11 and functional components. The housing 11 is configured to connect to the connection structure 10 at one end and to the wearable device 220 at the other end. The functional components include a processor 16 and an air pump 13. The processor 16 is connected to a pressure sensor 18. The air pump 13 is configured to connect to an air nozzle 2251 and inflate the pressure-measuring airbag 225 through the air nozzle 2251.

[0113] Understandably, in this embodiment, the pressure-measuring airbag 225 serves as both a detection airbag and a wearable component 220, achieving an integrated design that makes the airbag and wearable component 220 more compact. Furthermore, the size of the inflatable portion of the pressure-measuring airbag 225 (referring to its size in its uninflated state) is controlled by the connecting structure 10, allowing it to adapt to different users' measurement sites (e.g., wrist circumference). Users will not experience any impact on the accuracy of blood pressure measurement due to variations in the inflation degree of the pressure-measuring airbag 225 caused by wearing it too loosely or too tightly. This is because blood pressure values ​​are determined based on the air pressure in the pressure-measuring airbag 225, and different inflation degrees result in different reaction forces of the airbag wall against the air pressure, potentially leading to errors. However, in this embodiment, users can adjust the connection position according to their wrist circumference, thus varying the size of the inflatable portion of the pressure-measuring airbag 225, reducing the impact of airbag wall inflation on the measured blood pressure value.

[0114] It should be noted that the pressure-measuring airbag 225 in this embodiment can be structurally equivalent to the second airbag in the previous embodiment. The second airbag is directly used as the blood pressure detection airbag; that is, the blood pressure value is determined by measuring the air pressure value in the second airbag. The difference between this embodiment and the previous embodiment is that the electronic device provided in this embodiment omits the first airbag. Of course, in some embodiments, the pressure-measuring airbag 225 may not be attached to the mesh structure. The technical features in this embodiment can refer to the explanations of the technical features in some of the foregoing embodiments, such as the explanations of the host 1 and the connection structure 10, which will not be repeated here.

[0115] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application, and such improvements and refinements are also considered to be within the protection scope of this application.
