Description

Technical Field

[0001] This utility model relates to the technical field of watch accessories, and in particular to a watch strap. Background Technology

[0002] Currently, most smartwatches consist of a watch head and a watch band connected to it. To measure blood pressure, an air bladder is typically mounted on the watch band, while the watch head houses the air pump, circuit board, and pressure sensor. The circuit board within the watch head controls the air pump to inflate and deflate the air bladder. The pressure sensor detects changes in arterial pressure and transmits the detected pressure value to the circuit board, which then calculates the blood pressure based on this value. However, this method relies entirely on the watch head; if the watch band is replaced with a different watch head, the watch can no longer measure blood pressure. Utility Model Content

[0003] The main purpose of this invention is to provide a watch strap that solves the problem that existing smartwatches require the watch head and watch strap to work together to measure blood pressure.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0009] A blood pressure detection unit, mounted on a protective casing or belt and electrically connected to a circuit board, is used to detect human blood pressure.

[0010] Furthermore, the circuit board is a flexible circuit board, which is disposed inside the watch strap or protective case.

[0011] Furthermore, the blood pressure detection unit employs a photoelectric sensor mounted on a protective casing and electrically connected to a circuit board; the photoelectric sensor generates a pulse wave electrical signal based on the intensity of reflected light from blood fluctuations caused by the human heartbeat, and feeds the pulse wave electrical signal back to the circuit board; the circuit board calculates the blood pressure value based on the pulse wave electrical signal.

[0012] Alternatively, the circuit board integrates an MCU and an air pump drive circuit electrically connected to the MCU. The blood pressure detection unit includes an air pump electrically connected to the air pump drive circuit, an air bladder connected to the air pump, and a pressure sensor electrically connected to the MCU. The air pump is mounted on a protective shell or belt, and the air bladder is positioned along the length of the inner wall of the belt. The air pump drive circuit drives the air pump to inflate and deflate the air bladder according to the electrical signal output by the MCU. When the air bladder is inflated, it applies pressure to the user's wrist. The pressure sensor is used to detect the pressure value when the user's pulse beats and generates a pulse wave electrical signal to be fed back to the MCU. The pressure sensor is also used to detect the pressure value change during the inflation and deflation of the air bladder and generates an amplitude change electrical signal to be fed back to the MCU.

[0016] Furthermore, the watchband also includes housings for mounting circuit boards, blood pressure detection units, wireless transmission units, physiological index acquisition units, batteries, and wireless charging coils, respectively, with the housings disposed on the outer side of the watchband body; or a groove is formed on or inside the watchband body, with the housing placed in the groove and interference-fitted with the groove.

[0017] The housing has a wiring hole that communicates with the interior for wiring, and the watch strap body has multiple wiring channels. These multiple wiring channels are wires that connect the circuit board, blood pressure detection unit, wireless transmission unit, physiological index acquisition unit, battery, and wireless charging coil to each other.

[0019] Furthermore, the physiological index acquisition unit collects a fall sensor and an acceleration sensor that are electrically connected to the circuit board and installed inside the watch strap body; the circuit board determines whether the user has fallen based on the electrical signal fed back by the fall sensor, and uploads the data to the cloud via a wireless transmission unit when the user is determined to have fallen; the circuit board calculates motion values ​​based on the electrical signal fed back by the acceleration sensor, and the motion values ​​are one or more of the following: number of steps, distance traveled, and calories burned.

[0020] The watchband also includes an alarm module electrically connected to the circuit board and disposed on the watchband body. The alarm module is used to issue an alarm signal when the circuit board determines that the user has fallen or when the physiological index exceeds the threshold.

[0021] The watch band also includes a positioning unit electrically connected to the circuit board for detecting the user's position, and the positioning unit is disposed within the watch band body; when the circuit board determines that the user has fallen, it uploads the position information located by the positioning unit to the terminal via a wireless transmission module;

[0023] Furthermore, it also includes a display electrically connected to the circuit board; the display is used to display physiological indices and test values;

[0024] The watchband also includes a switch that is electrically connected to the circuit board and disposed on the watchband body; the circuit board is used to receive electrical signals from the user operating the switch and / or receive electrical signals from the APP terminal, and to activate the detection function or switch the physiological index displayed on the display.

[0025] Furthermore, the strap body and the protective shell are integrally injection molded. The strap body includes an upper strap and a lower strap, both of which are connected to the protective shell at one end. The airbag is disposed on the lower surface of the lower strap at the end near the head of the watch.

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] See attached document Figure 1-12 A watch strap 10 in one embodiment of this utility model.

[0048] The watch strap 10 includes a strap body 1 worn on the wrist, a circuit board 3 and a blood pressure detection unit 2 disposed on the strap body 1, wherein the strap body 1 is detachably connected to the watch head 00, and the blood pressure detection unit 2 is electrically connected to the circuit board 3 for detecting human blood pressure.

[0049] In this embodiment, blood pressure detection is achieved by configuring a circuit board 3 and a blood pressure detection unit 2 on the watch. Blood pressure measurement can be performed on the user without configuring a watch head 00, which is convenient for the user. In addition, the user can replace the watch head 00 to meet the user's needs for different watch heads 00, thus solving the problem that existing smart watches require a watch band and a watch head 00 to cooperate in order to achieve blood pressure measurement.

[0050] See attached document Figure 1-11In one possible implementation, the circuit board 3 is a flexible circuit board disposed within the watchband body 1. The flexible circuit board is flexible and can be bent to fit the watchband 10, so that when the watchband 10 is fixed on the user's wrist, the circuit board 3 does not affect the use of the watchband 10, allowing the watchband 10 to conform to the wrist so that the blood pressure detection unit 2 can conform to the user's wrist for better blood pressure measurement.

[0051] To enable the blood pressure detection unit 2 to measure blood pressure, the blood pressure detection unit 2 can adopt the following structure.

[0052] The first structure of the blood pressure detection unit 2: The blood pressure detection unit 2 includes a photoelectric sensor 24 disposed on the watchband body 1 and electrically connected to the circuit board 3. When the watchband 10 is fixed on the wrist and blood pressure is measured, the photoelectric sensor 24 is aligned with the artery on the wrist. The emitted light from the photoelectric sensor 24 shines on the artery. Due to the fluctuation of blood in the artery caused by the human heartbeat, the intensity of the reflected light changes, resulting in different light intensities received by the receiving end of the photoelectric sensor 24, thus generating a pulse wave electrical signal. This pulse wave electrical signal is fed back to the circuit board 3, which calculates the blood pressure value based on the pulse wave electrical signal to measure the blood pressure. In practical applications, the inner wall of the watchband body 1 has through holes or light-transmitting material at the positions corresponding to the emitting and receiving ends of the photoelectric sensor 24 to avoid affecting the blood pressure measurement.

[0053] The second structure of the blood pressure detection unit 2: The circuit board 3 integrates an MCU 34 and an air pump drive circuit 35 electrically connected to the MCU 34. The blood pressure detection unit 2 employs an air pump 23 electrically connected to the air pump drive circuit 35, an air bladder 21 connected to the air pump 23, and a pressure sensor 22 electrically connected to the MCU 33. The air pump 23 is located inside the watchband body 1, and the air bladder 21 is positioned along the length of the inner wall of the watchband body 1. The air bladder 21 applies pressure to the user's wrist when inflated by the air pump 23. The pressure sensor 22 detects the pressure value during the user's pulse beat and generates a pulse wave electrical signal that is fed back to the MCU 34. The pressure sensor 22 also detects the pressure value change during the inflation and deflation of the air bladder 21 and generates an amplitude change electrical signal that is fed back to the MCU 22. The MCU 22 calculates the blood pressure value based on the pulse wave electrical signal and the amplitude change electrical signal to achieve blood pressure measurement.

[0054] The air pump 23 is installed inside the watch strap body 1 and is installed along the thickness direction or the length and width direction of the circuit board 3.

[0055] In one possible implementation, the watchband 10 further includes a battery 5 and a wireless charging coil 6 electrically connected to the circuit board 3 and disposed within the watchband body 1. The battery 5 supplies power to the circuit board 3, and the wireless charging coil 6 can be used with existing smartwatch wireless chargers on the market, allowing the circuit board 3 to charge the battery 5. Of course, in other embodiments, the battery 5 may also be a disposable battery, non-rechargeable, etc. Alternatively, in embodiments with the battery 5, the watchband 10 further includes charging contacts electrically connected to the circuit board 3, which can also charge the battery 5 when an external adapter is used.

[0056] In one possible implementation, the watch strap body 1 includes a protective shell 13 and a strap body 19 connected to the protective shell 13. The protective shell 13 has a mounting groove 131 for placing the watch head 00. A circuit board 3 is disposed on the strap body 19 or the protective shell 13, an air pump 23 is disposed on the strap body 19 or the protective shell 13, a battery 5 is disposed on the strap body 19 or the protective shell 13, and an air bladder 21 is disposed along the length of the strap body 19. Figure 1 As shown. Thus, the meter head 00 can be detachably installed in the mounting slot to secure it. Specifically, the sidewall of the mounting slot 131 is a soft rubber structure, meaning that when the meter head 00 is placed in the mounting slot 131, it can be wrapped and secured, facilitating user replacement of the meter head 00. It should also be understood that the user can place the circuit board 3, battery 5, wireless charging coil 6, and air pump 23 in the desired positions as needed; their specific positions are not limited here. 11

[0057] In other embodiments, such as Figure 2 As shown, the watch strap body 1 includes a strap body 19, and both ends of the strap body 19 are provided with connectors 13 that can be detachably connected to the watch head 00. Specifically, both ends of the watch strap body 1 are detachably fixed to the watch head 00, realizing the connection with the watch head 00 and enabling the watch head 00 to be replaced.

[0058] In one possible implementation, the watch strap body 1 is provided with a storage slot 14 for placing medicines. A cover 141 is provided at the opening of the storage slot 14 to hold small pills for convenient use when the user is out. Specifically, the storage slot 14 can be provided on the strap body 19 or on the protective shell 13.

[0059] In one possible implementation, the watchband 10 further includes a physiological index acquisition unit 8 electrically connected to the circuit board 3. The physiological index acquisition unit 8 is used to acquire the physiological indices of the user in real time or periodically. These physiological indices include one or more of the following: blood pressure, heart rate, blood oxygen saturation, blood glucose, body temperature, blood lipids, uric acid, and exercise intensity. By acquiring one or more of these parameters through the physiological index acquisition module, the functionality and practicality of the watchband 10 in this embodiment can be improved, making it more convenient for the user.

[0060] In one possible implementation, the watchband 10 further includes a wireless transmission unit 7 electrically connected to the circuit board 3 for communication with a mobile terminal. The circuit board 3 is used to upload the blood pressure value collected by the blood pressure detection unit 2 and the physiological index collected by the physiological index acquisition unit 8 to the cloud 20 via the wireless transmission unit 7. This works in conjunction with the mobile terminal and the cloud 20 to enable monitoring. Specifically, the wireless transmission unit 7 can be a radio frequency module, such as a Bluetooth module, 2G module, 3G module, 4G module, 5G module, or 2.4G module.

[0061] In the above embodiments, the circuit board 3 can be integrally injection molded with the watchband body 1, or protrude from the watchband body 1. Alternatively, the watchband body 1 has grooves 15 corresponding to the positions of the circuit board 3, blood pressure detection unit 2, wireless transmission unit 7, physiological index acquisition unit 8, battery 5, and wireless charging coil 6. The circuit board 3, blood pressure detection unit 2, wireless transmission unit 7, physiological index acquisition unit 8, battery 5, and wireless charging coil 6 are placed in their respective matching grooves 15. The grooves 15 are provided with potting layers for respectively wrapping the circuit board 3, blood pressure detection unit 2, wireless transmission unit 7, physiological index acquisition unit 8, battery 5, and wireless charging coil 6, which can also fix the circuit board 3, blood pressure detection unit 2, wireless transmission unit 7, physiological index acquisition unit 8, battery 5, and wireless charging coil 6 to the watchband body 1. In another embodiment, the watchband 10 also includes a housing 4 for mounting the circuit board 3, blood pressure detection unit 2, wireless transmission unit 7, physiological index acquisition unit 8, battery 5, and wireless charging coil 6 respectively; the housing 4 may be disposed on the outside of the watchband body 1, or the housing 4 may be placed in the groove 15 and press-fitted with the groove 15 to fix the housing 4. Of course, in other embodiments, the housing 4 may also be snapped into the groove 15 to fix the housing 4, etc.

[0062] Furthermore, provided that the thickness of the watch strap 10 is sufficient, the flexible circuit board 3, blood pressure detection unit 2, wireless transmission unit 7, physiological index acquisition unit 8, battery 5, and wireless charging coil 6 can be arranged vertically or horizontally along the thickness direction of the watch strap 10; or, in order to reduce the thickness of the watch strap 10, the blood pressure detection unit 2, wireless transmission unit 7, physiological index acquisition unit 8, battery 5, and wireless charging coil 6 can be arranged along the width or length direction of the watch strap 10, etc.

[0063] In practical applications, the housing 4 has a wiring hole 41 that communicates with the interior and is used for wiring. The watch strap body 1 has multiple wiring channels 17. The multiple wiring channels 17 are wires that connect the circuit board 3, the blood pressure detection unit 2, the wireless transmission unit 7, the physiological index acquisition unit 8, the battery 5, and the wireless charging coil 6, so that the circuit board 3 can be electrically connected to the blood pressure detection unit 2, the wireless transmission unit 7, the physiological index acquisition unit 8, the battery 5, and the wireless charging coil 6 through wires.

[0064] Furthermore, in the embodiment where the blood pressure detection unit 2 includes an air pump 23, an air bag 21, and a pressure sensor 22, the housing 4 for mounting the air pump 23 is also provided with an air outlet 151 and an air inlet 152 connected to the air pump 23 via an air pipe 231, so that the air pump 23 can be connected to the air bag 21.

[0065] In one possible implementation, the physiological index acquisition unit 8 acquires data including a fall sensor 81 electrically connected to the circuit board 3 and disposed within the watchband body 1. The circuit board 3 determines whether the user has fallen based on the electrical signal fed back by the fall sensor 81. When the circuit board 3 determines that the user has fallen, it uploads the data to the cloud 20 via the wireless transmission unit 7. The cloud 20 can then notify the user who is using the watchband 10 in this embodiment, so that the user at the monitoring end can take appropriate action.

[0066] In one possible implementation, the watchband 10 further includes an alarm module 31 electrically connected to the circuit board 3 and disposed on the watchband body 1. The alarm module 31 is used to issue an alarm signal when the circuit board 3 determines that the user has fallen, so as to notify people nearby. The alarm module 31 is also used to notify the user wearing the watchband 10 when the physiological index of the circuit board 3 exceeds a threshold, so that the user can seek medical attention in time to avoid delays.

[0067] In one possible implementation, the watchband 10 further includes a positioning unit 32 electrically connected to detect the user's location. The positioning unit 32 is disposed within the watchband body 1. When the circuit board 3 determines that the user has fallen, it uploads the location information located by the positioning unit 32 to the terminal via the wireless transmission unit 7, so that the user at the monitoring end can know the specific location of the user wearing the watchband 10 and take timely action. The positioning unit 32 may be a GPS sensor, etc.

[0068] Specifically, in one possible implementation, the physiological index acquisition unit 8 acquires an accelerometer 82 electrically connected to the circuit board 3. The accelerometer 82 is located inside the watch strap body 1. The circuit board 3 calculates motion values ​​based on the electrical signals fed back by the accelerometer 82. The motion values ​​can be steps, distance traveled, calories burned, etc., so that the user can understand the motion values.

[0069] In one possible implementation, the watchband 10 also includes a heart rate sensor 83 electrically connected to the circuit board 3 and disposed within the watchband body 1. The circuit board 3 calculates the heart rate value based on the electrical signal fed back by the heart rate sensor 83 so that the user can know his / her own heart rate.

[0070] In one possible implementation, the watchband 10 also includes a display 18 electrically connected to the circuit board 3, the display 18 being used to display physiological indices and test values, wherein the test values ​​may be location information, etc.

[0071] The watch band 10 also includes a switch 33 electrically connected to the circuit board 3 and disposed on the watch band body 1. The circuit board 3 is used to receive electrical signals from the user operating the switch 33 and / or receive electrical signals from the APP terminal, and to activate the detection function or switch the physiological index displayed on the display 18.

[0072] In one possible implementation, the watch strap body 1 is length-adjustable to suit different wrist widths of users, thereby improving the applicability of the watch strap 10.

[0073] For details, please refer to the appendix. Figure 9-12 The strap body 19 includes an upper strap body 12 and a lower strap body 11, one end of which is detachably connected to the meter head 00. An airbag 21 is disposed on the lower surface of the lower strap body 1 at the end near the meter head 00. An air pump 23 and a pressure sensor 22 are disposed on the lower strap body 1 at the end near the meter head 00, with the air pump 23 located on the side of the pressure sensor 22 away from the airbag 21. The physiological index acquisition unit 8 and the wireless transmission unit 7 are both disposed on a circuit board 3, which is located on the lower strap body 1 at one end of the airbag 21. The battery 5 and the display screen 18 are both located at the end of the lower strap body 1 away from the meter head 00, with the display screen 18 on the same side as the airbag 21.

[0074] The upper watch strap body 12 has a through hole 121 at the end near the watch head 00. The lower surface of the upper watch strap body 12 has a second locking block 123 at the end away from the watch head 00. The lower watch strap body 11 has multiple second locking slots 113 extending along the length of the watch strap body 1 at the position corresponding to the airbag 21. When the watch strap body 1 is worn on the wrist, after the lower watch strap body 11 passes through the through hole 121 at the end away from the watch head 00, the second locking block 123 is placed in the second locking slots 113 in the direction near the watch head 00. The lower watch strap body 11 is folded back and forth at the end away from the watch head 00 and detachably connected to the upper watch strap body 12. With the circuit board 3, airbag 21, air pump 23, and pressure sensor 22 reasonably distributed, the length of the watch strap body 1 can be adjusted to accommodate different wrist sizes.

[0075] The upper watch strap body 12 has multiple third slots 123 extending along the length of the watch strap body 1. The lower surface of the lower watch strap body 11 has a third locking block 114 located away from the watch head 00. After the third locking block 114 is folded back and forth at one end of the lower watch strap body 11, it engages with the third slots 123 to fix the lower watch strap body 11 and the upper watch strap body 12 in a fixed connection.

[0076] Of course, in other embodiments, the lower watch strap body 11 is folded back and forth at the end away from the watch head 00 and then fixed to the upper watch strap body 11 by means of magnetic adsorption, Velcro, magnetic buckle, etc.

[0077] The lower watch strap body 11 includes a first watch segment 111 detachably connected to the watch head 00 and a second watch segment 112 connected to the first watch segment 111. The airbag 21 is located on the first watch segment 111 or the second watch segment 112. The circuit board 3 is at least partially located on the first watch segment 111. In this embodiment, the airbag 21, air pump 23, pressure sensor 22, and second slot 113 are all located on the first watch segment 111. The length of the second watch segment 112 can be the same as the length of the upper watch strap body 12, but is not limited to the above. The width of the through hole 121 is greater than the width of the second watch segment 112, but less than the width of the first watch segment 111, so that the circuit board 3, airbag 21, air pump 23, and pressure sensor 22 are placed on the strap body 19, and the watch strap body 1 can be worn stably.

[0078] The length of the airbag 21 can be 8-15cm (but not limited to the above). The second slots 113 are arranged in two rows and are located near the sides of the first watch section 111 to allow the watch strap body 1 to adapt to different wrist sizes. Specifically, the length of the airbag 21 is 13cm.

[0079] In practical applications, the upper watch strap body 12 and the lower watch strap body 11 may not be connected to the watch head 00. In this state, the two ends of the upper watch strap body 12 and the lower watch strap body 11 can be detachably connected to form the wrist strap 100.

[0080] This embodiment also provides a user monitoring and management system adapted to the above-mentioned watch strap for user use. For example, the watch strap can be used on elderly people living alone, allowing their children far away to understand their parents' physiological indicators, thereby monitoring the health of the watch strap user and promptly addressing any abnormalities, thus improving the health management of elderly people living alone.

[0081] See attached document Figure 13 The user monitoring and management system includes the watchband described above and a cloud platform 20 that communicates with the watchband. The cloud platform 20 receives and monitors physiological indices transmitted by the wireless transmission unit 7, and sends a first alarm signal to the wireless transmission unit 7 when the physiological indices exceed preset values. The circuit board 3 receives the first alarm signal from the cloud platform 20 via the wireless transmission unit 7 and issues an alarm through the alarm module 31, so that the watchband user can understand their physical condition and make an appointment with a doctor in a timely manner. Specifically, the alarm module 31 can be an indicator light or a horn electrically connected to the circuit board 3.

[0082] In one possible implementation, the user monitoring and management system further includes a monitoring terminal 30 that communicates with the cloud 20. The cloud 20 is also used to send a second alarm signal to the monitoring terminal 30 when physiological indices continuously exceed preset values ​​within a preset time period. The monitoring terminal 30 receives the second alarm signal and issues a reminder signal. Specifically, the monitoring terminal 30 can be a mobile phone, computer, smartwatch, etc., used to issue an alarm when the user's physiological indices are abnormal, thus providing a preventative reminder. The cloud 20 can be an app, and it is also used to transmit measurement execution signals to the watchband during user operation.
