A blood pressure measuring watch

Abstract

The present application relates to the field of electronic equipment, specifically a blood pressure measuring watch. The blood pressure measuring watch comprises a watch body, a watch strap, and a connecting device located between an airbag and the watch strap. The connecting device is capable of limiting relative lateral movement between the airbag and the watch strap, ensuring that the airbag and the watch strap are relatively stationary in the lateral direction without significant displacement. When the blood pressure measuring watch is worn, the connecting device allows for relative displacement between the end of the airbag away from the watch body and the watch strap by sliding along the length of the watch strap due to the inconsistency between the bending radius of the watch strap and the bending radius of the airbag. The end of the airbag away from the watch body is a free end, which prevents wrinkles and can accommodate people with different wrist circumferences.

Description

Technical Field

[0001] The present application relates to the field of electronic equipment, and in particular to a blood pressure measuring watch. Background Art

[0002] At present, electronic blood pressure monitors have become essential measuring instruments for patients with abnormal blood pressure. They are used to obtain their daily blood pressure conditions, and combined with the doctor's guidance, they can reasonably adjust their living habits and medication to control abnormal blood pressure and achieve treatment goals.

[0003] Traditional home-use arm or wrist blood pressure monitors based on the oscillometric method are large, heavy, and unportable, making them difficult to measure anytime, anywhere. Portable blood pressure measurement devices, such as blood pressure watches, are suitable for long-term wear. Existing blood pressure watches measure blood pressure by inflating and deflating an airbag worn on the user's wrist. However, the airbag is prone to wrinkling while the watch is worn, and the watch is not suitable for people with different wrist circumferences, resulting in a poor wearing experience. Summary of the Invention

[0004] An embodiment of the present application provides a blood pressure measuring watch. When a user wears the blood pressure measuring watch, the airbag will not wrinkle, and the watch can be adapted to people with different wrist circumferences.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, an embodiment of the present application provides a blood pressure measuring watch, which includes: a watch body; a strap for wearing the watch body on the user's wrist; an airbag for contacting the user's wrist when the watch body is worn on the user's wrist; a connecting device located between the airbag and the strap, the airbag being detachably mounted on the strap through the connecting device, and the connecting device being capable of limiting relative movement between the airbag and the strap in a lateral direction, where the lateral direction is the width direction of the strap; when the blood pressure measuring watch is worn, the connecting device is capable of allowing relative displacement of the airbag away from one end of the watch body and the strap along the length direction of the strap due to inconsistency between the bending radius of the strap and the bending radius of the airbag.

[0007] According to the implementation mode of the present application, the connecting device is located between the airbag and the watchband. When the user wears the blood pressure measuring watch, the blood pressure measuring watch looks beautiful. The airbag is detachably mounted on the watchband through the connecting device. The connecting device is equivalent to a binding device. When the user wears the blood pressure measuring watch, the airbag contacts the user's wrist, and the watchband and the airbag bend. The length direction of the watchband can also be understood as the direction of the wrist circumference. People with different wrist circumferences cause the bending radius of the watchband and the bending radius of the airbag to be inconsistent. The connecting device allows the airbag to generate relative displacement by sliding along the length direction of the watchband away from the end of the watch body. That is, the airbag and the watchband can slide relative to each other in the direction of the wrist circumference. This can adapt to people with different wrist circumferences and has a wide range of blood pressure measurement.

[0008] Compared with the method in which the airbag is fixed to the watch strap and cannot move in the direction of the wrist circumference, the movement of the airbag in the direction of the wrist circumference is not restricted. The end of the airbag away from the watch body is a free end, so that the airbag will not wrinkle, ensuring that the airbag is flat and stretched, which is conducive to the inflation and deflation of the airbag and ensures normal blood pressure measurement.

[0009] Then, during the blood pressure measurement process, the connecting device limits the relative movement of the airbag and the strap in the lateral direction, that is, the connecting device constrains the airbag to move laterally (along the length of the arm), ensuring that the airbag and the strap are relatively stationary in the lateral direction without obvious deviation; thereby ensuring that during the inflation process of the airbag, the strap can completely constrain the airbag to expand outward, so that the airbag expansion pressure acts completely inward on the wrist, effectively ensuring the accuracy of blood pressure measurement.

[0010] In one possible implementation of the first aspect described above, the connecting device includes: a first magnetic group, disposed on the watchband; and a second magnetic group, disposed on the airbag. When the airbag is mounted on the watchband, the second magnetic group and the first magnetic group attract each other. The first magnetic group is disposed on the surface of the watchband facing the airbag or on the interior of the watchband, and the second magnetic group is disposed on the outer surface of the airbag facing the watchband or on the inner surface of the airbag. The first magnetic group can be glued to the surface of the watchband or directly embedded in the interior of the watchband during the molding process. The second magnetic group can be glued to the surface of the airbag or directly embedded in the interior of the airbag during the molding process.

[0011] In addition, there is no restriction on the materials of the first magnetic group and the second magnetic group. The first magnetic group includes magnetic materials such as flexible magnetic textiles, liquid magnets, and hard magnetic blocks, and the second magnetic group includes magnetic materials such as flexible magnetic textiles, liquid magnets, and hard magnetic blocks.

[0012] Since the first magnetic group and the second magnetic group attract each other, the airbag is installed on the strap by magnetic force. By controlling the structure and material of the first magnetic group and the second magnetic group, the magnetic force and the damping of relative sliding between the first magnetic group and the second magnetic group can be controlled to an appropriate degree, ensuring that the airbag and the strap can produce relative displacement along the length direction when the user needs it.

[0013] In one possible implementation of the first aspect, the first magnetic group and the second magnetic group are coupled by a limiting structure. When the second magnetic group and the first magnetic group are attracted to each other, the limiting structure restricts lateral relative movement between the airbag and the watchband. With the limiting structure in place, lateral relative movement between the airbag and the watchband is further restricted, ensuring that the expansion pressure of the airbag during inflation is fully applied inward to the wrist.

[0014] In a possible implementation of the first aspect above, the limiting structure includes a recessed portion provided on one of the first magnetic group and the second magnetic group, and a convex portion corresponding to the recessed portion provided on the other, and the lateral relative movement is limited by the combination of the recessed portion and the convex portion.

[0015] In a possible implementation of the first aspect above, the first magnetic group includes a first magnetic member and a second magnetic member spaced apart along the width direction, and the first magnetic member and the second magnetic member are respectively distributed in a row on the strap along the length direction; the second magnetic group includes a third magnetic member and a fourth magnetic member spaced apart along the width direction, and the third magnetic member and the fourth magnetic member are respectively distributed in a row on the airbag along the length direction. The polarity of the magnetic material on the contact surface of the first magnetic member and the third magnetic member is opposite, thereby ensuring that the first magnetic member and the third magnetic member are attracted to each other, and the polarity of the magnetic material on the contact surface of the second magnetic member and the fourth magnetic member is opposite, thereby ensuring that the second magnetic member and the fourth magnetic member are attracted to each other. That is, the first magnetic member, the second magnetic member, the third magnetic member and the fourth magnetic member extend respectively in the length direction. In one embodiment, along the width direction, the widths of the first magnetic member and the third magnetic member are equal, and the widths of the second magnetic member and the fourth magnetic member are equal.

[0016] During the installation of the airbag on the watchband, the first magnetic part corresponds to the third magnetic part, the second magnetic part corresponds to the fourth magnetic part, and the first magnetic part and the third magnetic part are attracted to each other to form a first set of magnetic structures; the second magnetic part and the fourth magnetic part are attracted to each other to form a second set of magnetic structures. By setting up two sets of magnetic structures, the connection reliability between the airbag and the watchband is improved, and the relative movement of the airbag and the watchband in the lateral direction is further restricted, which is conducive to improving the accuracy of blood pressure measurement. There is no limit on the number of magnetic parts. It can be a first magnetic part and a third magnetic part, and the first magnetic part and the third magnetic part are attracted to each other.

[0017] In a possible implementation manner of the first aspect above, the first magnetic member, the second magnetic member, the third magnetic member, and the fourth magnetic member are respectively magnetic strips or multiple magnetic blocks.

[0018] When the first magnetic member, the second magnetic member, the third magnetic member and the fourth magnetic member are magnetic strips respectively, the first magnetic member and the second magnetic member are respectively continuously distributed along the length direction on the strap, and the third magnetic member and the fourth magnetic member are respectively continuously distributed along the length direction on the airbag.

[0019] When the first magnetic member, the second magnetic member, the third magnetic member and the fourth magnetic member are respectively multiple magnetic blocks, the first magnetic member and the second magnetic member are respectively discretely distributed along the length direction of the watch strap, that is, they are distributed in an array manner on the watch strap; the third magnetic member and the fourth magnetic member are respectively discretely distributed along the length direction of the airbag, that is, they are distributed in an array manner on the airbag. This can effectively reduce the impact of the mechanical structure of the magnetic material on the mechanical structure of the airbag and the watch strap. The first magnetic member, the second magnetic member, the third magnetic member and the fourth magnetic member can be made of flexible magnetic materials or hard magnetic materials. The third magnetic member and the fourth magnetic member are fixed to the airbag in a regular array manner. The distance between adjacent array elements can be determined according to the tightness resolution of the watch strap design, such as 5mm. The array arrangement of the first magnetic member corresponds one-to-one with the array arrangement of the third magnetic member, and the array arrangement of the second magnetic member corresponds one-to-one with the array arrangement of the fourth magnetic member.

[0020] Furthermore, there are no restrictions on the distribution of the first and third magnetic members. The first magnetic member may be a magnetic strip or multiple magnetic blocks, and the third magnetic member that is mutually attracted to the first magnetic member may be a magnetic strip or multiple magnetic blocks. There are no restrictions on the distribution of the second and fourth magnetic members. The second magnetic member may be a magnetic strip or multiple magnetic blocks, and the fourth magnetic member that is mutually attracted to the second magnetic member may be a magnetic strip or multiple magnetic blocks.

[0021] In a possible implementation of the first aspect above, the outer edge of the first magnetic part in the longitudinal direction is flush with an outer edge of the strap in the longitudinal direction, and the outer edge of the second magnetic part in the longitudinal direction is flush with the other outer edge of the strap in the longitudinal direction; the outer edge of the third magnetic part in the longitudinal direction is flush with an outer edge of the airbag in the longitudinal direction, and the outer edge of the fourth magnetic part in the longitudinal direction is flush with the other outer edge of the airbag in the longitudinal direction.

[0022] When attaching the airbag to the watchband, the width of the airbag is aligned with the width of the watchband, ensuring the airbag and watchband are equal in width. The first and third magnetic members, and the second and fourth magnetic members, are then attracted to each other, enabling rapid positioning of the corresponding magnetic structures of the airbag and watchband, and ensuring a precise magnetic connection. Furthermore, the outer longitudinal sides of the airbag and watchband are magnetically attracted to each other, enhancing the reliability of the connection and enabling accurate relative displacement of the airbag and watchband along their length.

[0023] In a possible implementation of the first aspect above, the first magnetic group and the second magnetic group are both electromagnets and are respectively connected to a control unit via wires. The control unit is used to control the direction or intensity of the current passing through the first magnetic group and the second magnetic group.

[0024] In this way, the sliding friction between the strap and the airbag can be adjusted according to user needs: when the relative position of the strap and the airbag needs to be adjusted, the current intensity passing through the first magnetic group and the second magnetic group is reduced or turned off, thereby reducing the attraction between the strap and the airbag and facilitating the adjustment of the relative position; during the blood pressure measurement process, if the relative position of the strap and the airbag needs to be fixed, the current intensity passing through the first magnetic group and the second magnetic group can be increased, thereby increasing the attraction between the strap and the airbag.

[0025] In a possible implementation of the first aspect above, the connecting device includes: a first sliding portion, provided on the watch strap; a second sliding portion, provided on the airbag, the second sliding portion and the first sliding portion cooperate with each other to limit the relative movement of the airbag and the watch strap in the lateral direction, and in addition, the end of the second sliding portion away from the watch body and the first sliding portion can slide relative to each other along the length direction when the blood pressure measuring watch is worn to adapt to the relative displacement of the end of the airbag away from the watch body and the watch strap along the length direction of the watch strap.

[0026] In one possible implementation of the first aspect described above, one of the first and second sliding parts includes a groove extending along its length, and the other includes a protrusion extending along its length that mates with the groove. When the protrusion is positioned within the groove, the two parts do not separate in the thickness direction, and the thickness, length, and width directions are mutually perpendicular. By installing the protrusion within the groove, the second sliding part is mounted to the first sliding part, and the airbag is subsequently mounted to the watch strap. With the protrusion within the groove, lateral movement of the airbag and watch strap is restricted, allowing the end of the second sliding part distal from the watch body to slide along the groove of the first sliding part via the protrusion.

[0027] In one possible implementation of the first aspect, the first sliding portion includes a first sliding member and a second sliding member spaced apart along the width direction, the first sliding member and the second sliding member being arranged in a row along the length direction on the watchband; the second sliding portion includes a third sliding member and a fourth sliding member spaced apart along the width direction, the third sliding member and the fourth sliding member being arranged in a row along the length direction on the airbag, the first sliding member and the third sliding member cooperating with each other, and the second sliding member and the fourth sliding member cooperating with each other. This arrangement improves the connection reliability between the airbag and the watchband, further limits relative lateral movement between the airbag and the watchband, and facilitates improved blood pressure measurement accuracy.

[0028] In a possible implementation of the first aspect above, the outer edge of the first sliding member in the longitudinal direction is flush with an outer edge of the strap in the longitudinal direction, and the outer edge of the second sliding member in the longitudinal direction is flush with the other outer edge of the strap in the longitudinal direction; the outer edge of the third sliding member in the longitudinal direction is flush with an outer edge of the airbag in the longitudinal direction, and the outer edge of the fourth sliding member in the longitudinal direction is flush with the other outer edge of the airbag in the longitudinal direction.

[0029] During the installation process, the first and third sliders, followed by the second and fourth sliders, quickly attach the airbag to the watchband. The two sets of sliders connect the airbag and watchband, improving their reliability and enabling precise longitudinal displacement.

[0030] In a possible implementation of the first aspect above, it also includes: a micropump connected to the inner cavity air path of the airbag, used to inflate or deflate the inner cavity; an air pressure sensor connected to the inner cavity air path of the airbag, used to detect the pressure signal of the inner cavity during the process of inflation or deflation of the micropump; during the relative movement of the airbag and the strap along the length direction, the micropump and the airbag maintain air path communication, and the air pressure sensor and the airbag maintain air path communication.

[0031] When a user wears the blood pressure watch, during the blood pressure measurement process, the micropump controls the inner cavity of the airbag to inflate air, which compresses the user's blood vessels, blocking blood flow. The micropump then deflates the inner cavity of the airbag, allowing blood to flow again. The vibrations caused by the blood during this process reflect changes in blood pressure within the blood vessels. Therefore, the pressure signal within the airbag cavity, detected by the air pressure sensor, can be used to measure blood pressure.

[0032] In one possible implementation of the first aspect, the micropump and the air pressure sensor are disposed within the watch body, and the airbag is connected to the watch body. Integrating the micropump and the air pressure sensor within the watch body simplifies the structure of the airbag, making the blood pressure measurement watch more comfortable for users to wear for a long time.

[0033] In one possible implementation of the first aspect, the watch strap includes a first strap and a second strap located at opposite ends of a watch body, the first strap and the second strap being rotatably connected to the watch body, respectively. The airbag is provided on the first strap or the second strap, and a fixing device is provided at the end of the first strap and the end of the second strap remote from the watch body, the fixing device being used to attach the blood pressure measuring watch to the user's wrist. The specific structure of the fixing device is not limited and includes structures such as a folding clasp, a pin buckle, and a butterfly buckle that can connect the end of the first strap remote from the watch body to the end of the second strap.

[0034] It should be understood that the foregoing general description and the following detailed description are merely illustrative and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0060] Blood pressure refers to the lateral pressure perpendicular to the vessel wall exerted by the pulsating blood flow. The peak pressure is systolic pressure, also known as high pressure, while the valley pressure is diastolic pressure, also known as low pressure. Blood pressure is a key indicator for health monitoring, reflecting a person's health. Therefore, how to conveniently and accurately measure blood pressure has become a hot topic.

[0061] Figure 1 This is a structural diagram of a blood pressure measuring watch in the embodiment of the present application, combined with Figure 2 and Figure 3 As shown, the blood pressure measuring watch includes: a watch body 302, a watch strap, an airbag 305, a micropump (not shown), an air pressure sensor (not shown) and a connecting device 306, wherein the watch strap is used to wear the watch body 302 on the user's wrist; the airbag 305 is used to contact the user's wrist when the watch body 302 is worn on the user's wrist. In order to facilitate blood pressure measurement, the airbag 305 is usually made of a flexible material. For example, the airbag 305 can be made of thermoplastic polyurethane (TPU), polyvinyl chloride (PVC) or silicone; the connecting device 306 is located between the airbag 305 and the watch strap; the micropump is connected to the inner cavity air path of the airbag 305 for inflating or deflating the inner cavity; the air pressure sensor is connected to the inner cavity air path of the airbag 305 for detecting the pressure signal of the inner cavity during the process of inflation or deflation of the micropump.

[0062] In the embodiment of the present application, the micropump and air pressure sensor are located within the watch body 302, and the airbag 305 is connected to the watch body 302. Integrating the micropump and air pressure sensor within the watch body 302 simplifies the structure of the airbag 305, making it more comfortable for the user to wear the blood pressure measurement watch for a long time. The placement of the micropump and air pressure sensor is not limited; they can each be connected to the airbag 305 through a pneumatic path. In some embodiments, the micropump is located within the watch body 302, and the air pressure sensor is located on the airbag 305. In some embodiments, the micropump and air pressure sensor are integrated on the airbag 305.

[0063] In addition, in the embodiment of the present application, the watch strap includes a first watch strap 301 and a second watch strap 303 located at opposite ends of the watch body 302. The first watch strap 301 and the second watch strap 303 are respectively rotatably connected to the watch body 302. The airbag 305 is provided on the first watch strap 301 or the second watch strap 303. The ends of the first watch strap 301 and the second watch strap 303 away from the watch body 302 are provided with a fixing device 304. When a user wears the blood pressure measurement watch, they place the watch body 302 in contact with the user's wrist, bend the first watch strap 301 and the second watch strap 303, and securely connect them via the fixing device 304 to wear the blood pressure measurement watch on the user's wrist. The tightness of the watch strap can be adjusted by adjusting the connection position of the first watch strap 301, the second watch strap 303, and the fixing device 304.

[0064] It should be noted that the specific structure of the fixing device 304 is not limited, and includes structures such as folding buckles, pin buckles, and butterfly buckles that can connect the end of the first strap 301 away from the watch body 302 and the end of the second strap 303.

[0065] In the present application, the airbag 305 is detachably mounted on the watchband via the connecting device 306. Specifically, in this embodiment, the airbag 305 is detachably mounted on the first watchband 301 via the connecting device 306. In some embodiments, the airbag 305 is detachably mounted on the second watchband 303 via the connecting device 306. In the embodiment of the present application, taking the airbag 305 being mounted on the first watchband 301 as an example, the connecting device 306 can limit the airbag 305 and the first watchband 301 from moving in the horizontal direction ( Figure 3 When the blood pressure measuring watch is worn, the connecting device 306 can allow the bending radius of the first strap 301 and the bending radius of the airbag 305 to be inconsistent, so that the end of the airbag 305 away from the watch body 302 and the strap along the length direction of the strap ( Figure 1 The Y direction in the figure produces a relative displacement.

[0066] Because the connecting device 306 is located between the airbag 305 and the first watchband 301, the blood pressure measurement watch looks beautiful when worn by the user. The airbag 305 is detachably attached to the first watchband 301 via the connecting device 306. The connecting device 306 acts as a binding device. When the user wears the blood pressure measurement watch, the airbag 305 contacts the user's wrist, causing the first watchband 301 and the airbag 305 to bend. The length direction of the first watchband 301 can also be understood as the direction of the wrist circumference. People with different wrist circumferences will have different bending radii between the first watchband 301 and the airbag 305. The connecting device 306 allows the end of the airbag 305 away from the watch body 302 and the first watchband 301 to slide relative to each other along the length direction of the first watchband 301.

[0067] That is, the airbag 305 and the first strap 301 can slide relative to each other along the wrist circumference, thereby adapting to people with different wrist circumferences and expanding the blood pressure measurement range. During the relative movement of the airbag 305 and the first strap 301 along the length direction, the micropump maintains air communication with the airbag 305, and the air pressure sensor maintains air communication with the airbag 305.

[0068] Compared with the method in which the airbag 305 is fixed to the watch strap and cannot move in the direction of the wrist circumference, the movement of the airbag 305 in the direction of the wrist circumference of this embodiment is not restricted. The end of the airbag 305 away from the watch body 302 is a free end, so that the airbag 305 will not be wrinkled, ensuring that the airbag 305 is flat and stretched, which is conducive to the inflation and deflation of the airbag 305 and ensures normal blood pressure measurement.

[0069] Then, after the user wears the blood pressure measurement watch, during the blood pressure measurement process, the connecting device 306 restricts the airbag 305 and the first strap 301 from relative lateral movement. That is, the connecting device 306 constrains the airbag 305 from lateral movement (along the arm's length), ensuring that the airbag 305 and the first strap 301 are relatively stationary in the lateral direction and do not significantly deviate. When the micropump is controlled to inflate the inner cavity of the airbag 305, the first strap 301 can fully constrain the airbag 305 from expanding outward during the inflation process. This allows the inflation pressure of the airbag 305 to act completely inward on the wrist. The airbag 305 compresses the blood vessels in the user's wrist, blocking blood flow within the vessels. When the micropump then deflates the inner cavity of the airbag 305, the blood within the vessels resumes circulation. The vibration changes caused by the blood during this process can reflect the changes in blood pressure within the blood vessels. The pressure signal within the inner cavity of the airbag 305 detected by the air pressure sensor can be used to measure blood pressure. This effectively ensures the accuracy of blood pressure measurement.

[0070] In the examples of this application, reference Figure 3The first strap 301 and the airbag 305 have equal widths. There is no limitation on the width relationship between the first strap 301 and the airbag 305. In some embodiments, the width of the airbag 305 is greater than the width of the first strap 301. In some embodiments, the combined thickness of the strap, connecting device 306, and airbag 305 does not exceed the thickness of the watch body 302, making the blood pressure measurement watch aesthetically pleasing.

[0071] In one possible implementation, the blood pressure measurement watch further includes a signal processing unit configured to receive the pressure signal from the air pressure sensor. The signal processing unit may be a microcontroller unit or other unit capable of processing signals.

[0072] In one possible implementation, the blood pressure measurement watch further includes a circuit board, such as a printed circuit board, disposed within the watch body 302. The micropump, air pressure sensor, and signal processing unit are disposed on the circuit board, thereby achieving connection via the circuit board. Furthermore, the blood pressure measurement watch may further include components to ensure the normal operation of the blood pressure measurement watch, such as a power supply assembly, a display assembly, and a wireless communication assembly. The power supply assembly provides power to the blood pressure measurement watch, the wireless communication assembly enables communication with other devices, and the display assembly can be used to display the measured blood pressure value of the user.

[0073] As mentioned above, in this application, the airbag 305 is detachably mounted on the first strap 301 through the connecting device 306. The first strap 301 and the airbag 305 are aligned in the width direction. In the embodiment of this application, Figure 4 and Figure 5 The connecting device 306 is a magnetic material fixed to the first strap 301 and the air bag 305 respectively, such as iron, cobalt, nickel and their alloys, rare earth elements and their total, and some manganese metal compounds.

[0074] Specifically, the connecting device 306 includes a first magnetic group 402 disposed on the first strap 301 and a second magnetic group 401 disposed on the airbag 305. When the airbag 305 is attached to the first strap 301, the second magnetic group 401 and the first magnetic group 402 attract each other. The first magnetic group 402 is disposed on the surface of the first strap 301 facing the airbag 305 or on the inside of the strap, while the second magnetic group 401 is disposed on the outer surface of the airbag 305 facing the first strap 301 or on the inner surface of the airbag 305. The first magnetic group 402 can be glued to the surface of the first strap 301 or directly embedded in the first strap 301 during the molding process. The second magnetic group 401 can be glued to the surface of the airbag 305 or directly embedded in the airbag 305 during the molding process.

[0075] The directions of the magnetic field at the junction of the first magnetic group 402 and the second magnetic group 401 are opposite. If the polarity of the contact surface of the second magnetic group 401 is N, the polarity of the contact surface of the first magnetic group 402 in contact with it is S. Figure 4 If the polarity of the contact surface of the second magnetic group 401 is S, the polarity of the contact surface of the first magnetic group 402 in contact therewith is N, as shown Figure 5 shown.

[0076] Since the first magnetic group 402 and the second magnetic group 401 attract each other, the airbag 305 is installed on the first strap 301 by using magnetic force, ensuring that the entire airbag 305 is effectively fixed on the first strap 301. By controlling the structure and material of the first magnetic group 402 and the second magnetic group 401, the magnetic force and the damping of relative sliding between the first magnetic group 402 and the second magnetic group 401 can be controlled to an appropriate degree, ensuring that the airbag 305 and the first strap 301 can produce relative displacement along the length direction when the user needs it.

[0077] In some embodiments, first magnetic group 402 and second magnetic group 401 are coupled together by a limiting structure. When second magnetic group 401 and first magnetic group 402 are attracted to each other, the limiting structure restricts lateral relative movement between airbag 305 and first watchband 301. With the limiting structure in place, lateral relative movement between airbag 305 and first watchband 301 is further restricted, ensuring that the inflation pressure of airbag 305 during inflation is fully applied inward to the wrist.

[0078] refer to Figure 6 and Figure 7 In a possible implementation, the limiting structure includes a concave portion provided on the first magnetic group 402 and a convex portion provided on the second magnetic group 401 corresponding to the concave portion, and the combination of the concave portion and the convex portion is used to limit the lateral ( Figure 6 and Figure 7 Alternatively, the limiting structure includes a convex portion provided on the first magnetic group 402 and a concave portion provided on the second magnetic group 401 corresponding to the convex portion, and the lateral relative movement is limited by the combination of the concave portion and the convex portion. Figure 6 and Figure 7 , two convex portions spaced apart along the width direction are provided on the first magnetic group 402, and two concave portions spaced apart along the width direction are provided on the second magnetic group 401. In some embodiments, the first magnetic group 402 may have two convex portions and a concave portion spaced apart along the width direction, and the second magnetic group 401 may have two concave portions and a convex portion spaced apart along the width direction.

[0079] Figure 6 and Figure 7As shown in FIG, before the first magnetic group 402 and the second magnetic group 401 are attracted to each other, the first magnetic group 402 and the second magnetic group 401 are in the thickness direction ( Figure 6 and Figure 7 The first magnetic group 402 and the second magnetic group 401 are arranged relative to each other along the thickness direction, and accordingly, when the first magnetic group 402 and the second magnetic group 401 are attracted to each other along the thickness direction, the concave part and the convex part are combined. However, the limiting structure is not limited to this. In some embodiments, reference Figure 8 Before the first magnetic group 402 and the second magnetic group 401 are attracted to each other, the first magnetic group 402 and the second magnetic group 401 are staggered in the thickness direction. Accordingly, the first magnetic group 402 and the second magnetic group 401 can be attracted to each other along the width direction; that is, when the first magnetic group 402 and the second magnetic group 401 are attracted to each other, the first magnetic group 402 and the second magnetic group 401 are face to face in the width direction, which can also play a role in lateral limitation.

[0080] In addition, in some embodiments, a limiting structure may be provided on the airbag 305 and the first strap 301 to limit the relative movement of the airbag 305 and the first strap 301 in the lateral direction.

[0081] In some embodiments, the first magnetic group 402 may be configured as follows: Figure 9 The first magnetic group 402 includes a plurality of magnetic elements distributed in the width direction ( Figure 9 The first magnetic member 503 and the second magnetic member 504 are spaced apart along the length direction ( Figure 9 The first magnetic member 503 and the second magnetic member 504 are arranged in a row on the first watchband 301 (as shown in the Y direction). The first magnetic member 503 and the second magnetic member 504 are symmetrically distributed. In other words, the first magnetic member 503 and the second magnetic member 504 are magnetic strips. In other words, the first magnetic member 503 and the second magnetic member 504 are continuously distributed along the length direction of the first watchband 301.

[0082] The materials of the first magnetic member 503 and the second magnetic member 504 are not limited. The first magnetic member 503 includes magnetic materials such as flexible magnetic textiles, liquid magnets, and hard magnetic blocks. The second magnetic member 504 includes magnetic materials such as flexible magnetic textiles, liquid magnets, and hard magnetic blocks. In the embodiment of the present application, the lengths of the first magnetic member 503 and the second magnetic member 504 are equal to the length of the first watchband 301.

[0083] In some embodiments, the second magnetic group 401 can be configured as follows: Figure 10 The second magnetic group 401 includes a plurality of magnetic elements distributed in the width direction ( Figure 10The third magnetic member 501 and the fourth magnetic member 502 are spaced apart along the length direction ( Figure 10 The third magnetic member 501 and the fourth magnetic member 502 are arranged in a row on the airbag 305 (as shown in the Y direction). The third magnetic member 501 and the fourth magnetic member 502 are symmetrically distributed. That is, the third magnetic member 501 and the fourth magnetic member 502 are magnetic strips. In other words, the third magnetic member 501 and the fourth magnetic member 502 are continuously distributed along the length direction of the airbag 305.

[0084] The materials of the third magnetic member 501 and the fourth magnetic member 502 are not limited. The third magnetic member 501 can include a flexible magnetic textile, a liquid magnet, a hard magnetic block, or other magnetic materials. The fourth magnetic member 502 can include a flexible magnetic textile, a liquid magnet, a hard magnetic block, or other magnetic materials. In the embodiment of the present application, the length of the third magnetic member 501 and the fourth magnetic member 502 is equal to the length of the airbag 305.

[0085] Among them, the polarity of the magnetic material of the contact surface of the first magnetic member 503 and the third magnetic member 501 is opposite, thereby ensuring that the first magnetic member 503 and the third magnetic member 501 are attracted to each other, and the polarity of the magnetic material of the contact surface of the second magnetic member 504 and the fourth magnetic member 502 is opposite, thereby ensuring that the second magnetic member 504 and the fourth magnetic member 502 are attracted to each other. That is, the first magnetic member 503, the second magnetic member 504, the third magnetic member 501 and the fourth magnetic member 502 extend in the length direction respectively. In the embodiment of the present application, in the width direction, the width of the first magnetic member 503 and the third magnetic member 501 is equal, and the width of the second magnetic member 504 and the fourth magnetic member 502 is equal. However, the width relationship between the first magnetic member 503 and the third magnetic member 501, and the width relationship between the second magnetic member 504 and the fourth magnetic member 502 are not limited.

[0086] During the installation of the airbag 305 on the first watchband 301, the first magnetic member 503 aligns with the third magnetic member 501, and the second magnetic member 504 aligns with the fourth magnetic member 502. The first and third magnetic members 503 and 501 attract each other, forming a first set of magnetic structures. The second and fourth magnetic members 504 and 502 attract each other, forming a second set of magnetic structures. This arrangement improves the connection reliability between the airbag 305 and the first watchband 301 and further limits lateral relative movement between the airbag 305 and the first watchband 301, thereby improving blood pressure measurement accuracy.

[0087] In some embodiments, to maintain automatic alignment between the edges of the first watchband 301 and the airbag 305, the ratio of the width of the first watchband 301 to the width of the first magnetic member 503 and the second magnetic member 504, and the ratio of the width of the airbag 305 to the width of the third magnetic member 501 and the fourth magnetic member 502, respectively, need to be controlled within an appropriate value, such as 7:1. The smaller the ratio, the easier it is for the airbag 305 to adhere to the first watchband 301.

[0088] In addition, there is no limit on the number, size, or location of the magnetic structures provided on the first strap 301 and the airbag 305. The magnetic structures must be arranged to allow the first strap 301 and the airbag 305 to be attracted together by the magnetic force of the magnetic structures. In some embodiments, a first magnetic member 503 and a third magnetic member 501 may be provided, with the first magnetic member 503 located at the center of the first strap 301 and the third magnetic member 501 located at the center of the airbag 305, and the first magnetic member 503 and the third magnetic member 501 being attracted to each other.

[0089] In some embodiments, the first magnetic group 402 may be configured as follows: Figure 11 and Figure 13 Another form of distribution is shown, the first magnetic member 503 and the second magnetic member 504 are multiple magnetic blocks, the first magnetic member 503 and the second magnetic member 504 are discretely distributed along the length direction of the first strap 301, that is, distributed in the first strap 301 in an array manner. The second magnetic group 400 can be arranged according to Figure 12 and Figure 13 In another distribution form shown, the third magnetic member 501 and the fourth magnetic member 502 are respectively a plurality of magnetic blocks, and the third magnetic member 501 and the fourth magnetic member 502 are respectively discretely distributed in the airbag 305 along the length direction, that is, distributed in the airbag 305 in an array manner.

[0090] This can effectively reduce the impact of the mechanical structure of the magnetic material on the mechanical structure of the airbag 305 and the first strap 301. The first magnetic member 503, the second magnetic member 504, the third magnetic member 501, and the fourth magnetic member 502 can be made of either flexible or hard magnetic materials. The third magnetic member 501 and the fourth magnetic member 502 are fixed to the airbag 305 in a regular array. The distance between adjacent array elements can be determined based on the tightness resolution of the strap design, such as 5mm. The array arrangement of the first magnetic member 503 corresponds one-to-one to the array arrangement of the third magnetic member 501, and the array arrangement of the second magnetic member 504 corresponds one-to-one to the array arrangement of the fourth magnetic member 502.

[0091] Furthermore, there is no limitation on the distribution of the first magnetic member 503 and the third magnetic member 501. The first magnetic member 503 may be a magnetic strip or multiple magnetic blocks, and the third magnetic member 501, which is attracted to the first magnetic member 503, may be a magnetic strip or multiple magnetic blocks. There is no limitation on the distribution of the second magnetic member 504 and the fourth magnetic member 502. The second magnetic member 504 may be a magnetic strip or multiple magnetic blocks, and the fourth magnetic member 502, which is attracted to the second magnetic member 504, may be a magnetic strip or multiple magnetic blocks.

[0092] In some embodiments, reference Figures 9 to 12 The outer edge of the first magnetic component 503 in the longitudinal direction is flush with an outer edge of the first strap 301 in the longitudinal direction, and the outer edge of the second magnetic component 504 in the longitudinal direction is flush with the other outer edge of the first strap 301 in the longitudinal direction; the outer edge of the third magnetic component 501 in the longitudinal direction is flush with an outer edge of the airbag 305 in the longitudinal direction, and the outer edge of the fourth magnetic component 502 in the longitudinal direction is flush with the other outer edge of the airbag 305 in the longitudinal direction.

[0093] During the installation of the airbag 305 on the first watchband 301, the width of the airbag 305 is directly aligned with the width of the first watchband 301. The width of the airbag 305 is equal to the width of the first watchband 301. The first magnetic member 503 and the third magnetic member 501 are attracted to each other, and the second magnetic member 504 and the fourth magnetic member 502 are attracted to each other. This achieves rapid positioning of the corresponding magnetic structures of the airbag 305 and the first watchband 301, and a precise magnetic connection. Furthermore, the magnetic attraction between the outer longitudinal sides of the airbag 305 and the first watchband 301 enhances the connection reliability between the airbag 305 and the first watchband 301, allowing accurate relative displacement of the airbag 305 and the first watchband 301 in the longitudinal direction.

[0094] In some embodiments, reference Figures 14 to 16 The first magnetic group 402 is an electromagnet, and the first magnetic group 402 is connected to the control unit (not shown) in the meter body 302 through a wire 703. The second magnetic group 401 is an electromagnet, and the second magnetic group 401 is connected to the control unit in the meter body 302 through a wire 703. The control unit is used to control the direction or current intensity of the current passing through the first magnetic group 402 and the second magnetic group 401, so as to adjust the magnetic polarity of the first magnetic group 402 and the second magnetic group 401 and the magnetic intensity of mutual attraction.

[0095] In this way, the sliding friction between the first watchband 301 and the airbag 305 can be adjusted according to user needs: when the relative position of the first watchband 301 and the airbag 305 needs to be adjusted, the current intensity passing through the first magnetic group 402 and the second magnetic group 401 is reduced or turned off, thereby reducing the attraction between the first watchband 301 and the airbag 305 and facilitating the adjustment of the relative position; during the blood pressure measurement process, if the relative position of the first watchband 301 and the airbag 305 needs to be fixed, the current intensity passing through the first magnetic group 402 and the second magnetic group 401 can be increased, thereby increasing the attraction between the first watchband 301 and the airbag 305.

[0096] The distribution of the first magnetic group 402 and the second magnetic group 401 is shown in FIG. Figures 9 to 12 As shown and described above, the first magnetic group 402 and the second magnetic group 401 can be distributed continuously or discretely. Figure 15 3 shows that the first magnetic groups 402 are discretely distributed on the first strap 301 , that is, the first magnetic groups 402 are distributed in an array. Figure 16 3 shows that the second magnetic groups 401 are discretely distributed on the airbag 305 , that is, the second magnetic groups 401 are distributed in an array.

[0097] In summary, the connecting device 306 is a magnetic structure that effectively secures the airbag 305 and the first strap 301 together, preventing the airbag 305 from sliding laterally, thereby effectively ensuring the accuracy of blood pressure measurement. Furthermore, the first strap 301 and the airbag 305 can slide relative to each other along the arm circumference, thereby adapting to people with different wrist circumferences.

[0098] In addition to being a magnetic structure, the connecting device 306 can also be a sliding structure. Figure 17 and Figure 18 The connecting device 306 includes: a first sliding portion 801 provided on the first strap 301, and a second sliding portion 802 provided on the airbag 305. The second sliding portion 802 and the first sliding portion 801 cooperate with each other to limit the relative movement of the airbag 305 and the strap in the lateral direction. In addition, when the blood pressure measuring watch is worn, the end of the second sliding portion 802 away from the watch body 302 and the first sliding portion 801 can slide relative to each other in the length direction to adapt to the relative displacement of the end of the airbag 305 away from the watch body 302 and the first strap 301 along the length direction of the first strap 301.

[0099] In some embodiments, combined Figure 18 As shown, the first sliding portion 801 includes protrusions distributed along the length direction, and the second sliding portion 802 includes grooves distributed along the length direction and adapted to the protrusions. Figure 19 , when the protrusion is located in the groove, it will not be affected by the thickness direction ( Figure 19The two are separated (as shown in the Z direction), and the thickness, length, and width directions are perpendicular to each other. In some embodiments, the first sliding portion 801 includes grooves distributed along its length, and the second sliding portion 802 includes protrusions distributed along its length that match the grooves. By installing the protrusions in the grooves, the second sliding portion 802 is mounted to the first sliding portion 801, and the airbag 305 is then mounted to the first watchband 301.

[0100] After the protrusion is set in the groove, the air bag 305 and the first strap 301 are in the horizontal direction ( Figure 18 The movement of the second sliding portion 802 (shown in the X direction) is restricted, and the end of the second sliding portion 802 away from the watch body 302 can slide along the groove of the first sliding portion 801 through the protrusion, and then the end of the first strap 301 away from the watch body 302 and the airbag 305 can produce relative displacement to adapt to people with different wrist circumferences.

[0101] In some embodiments, reference Figure 18 , the first sliding portion 801 includes a Figure 18 The first sliding member 803 and the second sliding member 804 are arranged in a row along the length direction respectively on the first strap 301; the second sliding portion 802 includes a first sliding member 803 and a second sliding member 804 arranged in a row along the width direction ( Figure 18 The third sliding member 805 and the fourth sliding member 806 are arranged at intervals (shown in the X direction), and the third sliding member 805 and the fourth sliding member 806 are respectively distributed in a row along the length direction on the airbag 305, with reference to Figure 19 The first sliding member 803 and the third sliding member 805 cooperate with each other, and the second sliding member 804 and the fourth sliding member 806 cooperate with each other.

[0102] This arrangement improves the connection reliability between the airbag 305 and the first strap 301 and further limits the relative movement of the airbag 305 and the first strap 301 in the lateral direction, which is beneficial to improving the accuracy of blood pressure measurement.

[0103] In some embodiments, reference Figure 18 The outer edge of the first sliding member 803 in the longitudinal direction is flush with one outer edge of the first strap 301 in the longitudinal direction, and the outer edge of the second sliding member 804 in the longitudinal direction is flush with the other outer edge of the first strap 301 in the longitudinal direction; the outer edge of the third sliding member 805 in the longitudinal direction is flush with one outer edge of the airbag 305 in the longitudinal direction, and the outer edge of the fourth sliding member 806 in the longitudinal direction is flush with the other outer edge of the airbag 305 in the longitudinal direction.

[0104] During the installation of the airbag 305 on the first watchband 301, the first and third sliders 803 and 805 cooperate with each other, and the second and fourth sliders 804 and 806 cooperate with each other, quickly installing the airbag 305 on the first watchband 301. The connection between the airbag 305 and the first watchband 301 via two sets of sliders improves the reliability of the connection between the airbag 305 and the first watchband 301, allowing the airbag 305 and the first watchband 301 to accurately produce relative displacement in the longitudinal direction.

[0105] Thus, the present application uses the connecting device 306 to secure the airbag 305 to the watchband. The airbag 305 is immovable laterally relative to the watchband (along the length of the arm) but movable longitudinally (along the circumference of the arm). This ensures that the airbag 305 is aligned laterally with the watchband during blood pressure measurement and can accommodate people with different wrist circumferences. This improves the accuracy of blood pressure measurement and enhances the aesthetics and usability of the blood pressure measurement device.

Those skilled in the art may make various changes in form and detail, including simple deductions or substitutions, without departing from the spirit and scope of the present application.
