Description

Technical Field

[0001] This utility model relates to the field of watch strap technology, specifically a multimodal vital sign monitoring watch strap. Background Technology

[0002] Multimodal vital signs monitoring straps are wearable devices that integrate multiple sensor technologies to monitor various physiological indicators in real time, such as heart rate, blood pressure, blood oxygen, body temperature, electrocardiogram, and skin conductance. These devices achieve a comprehensive assessment of health status through data fusion algorithms and are widely used in daily health management and exercise tracking. Mainstream products use PPG sensors to monitor heart rate and blood oxygen. In daily life, it can monitor changes in various body indicators at all times, detect abnormalities in a timely manner and issue warnings. By monitoring heart rate, blood pressure and other data during exercise, it helps users scientifically adjust exercise intensity and pace.

[0003] The existing publication number CN213551747U discloses a vital signs monitoring wristband, including a monitoring device body. The instruction manual describes that the wristband is fixed by a magnetic locking element in the lock hole at the top and a locking pin at the bottom. When the locking pin is engaged with the magnetic locking element in the lock hole, the patient cannot actively remove the wristband unless a medical staff member unlocks it with a special magnetic unlocking device, thus avoiding the loss or damage of the wristband caused by arbitrarily removing it.

[0004] However, the aforementioned detection device installation and removal method applied to watch straps makes it inconvenient for users. The monitoring modules of traditional wearable devices are usually fixed to the watch straps by a buckle structure. The buckle structure often requires users to align with a specific slot and use a tool to pry open the buckle to complete the installation or removal. This operation method cannot be completed with one hand during exercise, and long-term frequent operation can easily cause the buckle to wear and deform, resulting in connection failure. Especially when it is necessary to frequently replace the module or deal with high-intensity sports scenarios, the user experience is poor. Utility Model Content

[0022] 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.

[0023] Please see Figures 1 to 6 This utility model provides a technical solution.

[0024] A multimodal vital signs monitoring watchband includes a watchband assembly and a monitoring module 11. The watchband assembly includes a left watchband 1 and a right watchband 4. The joint between the left watchband 1 and the right watchband 4 forms a cavity for accommodating the monitoring module 11. Positioning blocks 10 are fixedly connected to both sides of the monitoring module 11. The inner wall of the cavity is provided with positioning grooves 13 for the positioning blocks 10 to be embedded. A locking assembly for fixing the positioning blocks 10 is slidably connected inside the right watchband 4. The locking assembly includes a linkage rod 6 and a locking pin 8. The locking pin 8 and the linkage rod 6 are fixedly connected. The surface of the positioning block 10 is provided with a lock hole 9 for the locking pin 8 to be embedded. By sliding the linkage rod 6, the locking pin 8 can be driven to insert into or disengage from the lock hole 9, thereby locking or separating the monitoring module 11 from the watchband assembly. When the locking pin 8 is completely disengaged from the lock hole 9, the left watchband 1 and the right watchband 4 can be separated, and the monitoring module 11 can be removed from the cavity.

[0025] The right watch strap 4 has an internal sliding groove 12 for sliding the linkage rod 6. A return spring 7 is fixedly connected between the groove wall of the sliding groove 12 and the linkage rod 6. By setting the return spring 7, when the linkage rod 6 is pressed to slide and drive the locking pin 8 to disengage from the lock hole 9, when the linkage rod 6 is released, the elastic force of the return spring 7 will drive the linkage rod 6 to automatically return to its original position, so that the locking pin 8 returns to the initial standby position and waits for the next pressing operation.

[0026] A button 5 is fixedly connected to the end of the linkage rod 6. The button 5 is slidably connected to the right watch strap 4. The button 5 is exposed on the outer surface of the right watch strap 4, which makes it convenient for the user to press. After pressing the button 5, the linkage rod 6 is driven to slide along the track of the sliding groove 12.

[0027] A connecting rod 2 is fixedly connected to one side of the left watch strap 1. A telescopic groove for sliding the connecting rod 2 is provided on the surface of the right watch strap 4. A push spring 3 is fixedly connected between the connecting rod 2 and the inner wall of the telescopic groove. Through the connection of the connecting rod 2 and the push spring 3, the left watch strap 1 and the right watch strap 4 will not be completely disconnected. When the left watch strap 1 and the right watch strap 4 are connected, the connecting rod 2 is inserted into the telescopic groove, the push spring 3 is compressed and stores elastic force. After the locking pin 8 is completely disengaged from the lock hole 9 and the lock is released, the push spring 3 releases the stored elastic force, drives the connecting rod 2 to slide out of the telescopic groove quickly, so that the left watch strap 1 and the right watch strap 4 automatically separate, forming an opening for the monitoring module 11 to be removed.

[0028] Multiple flexible body temperature sensors are evenly distributed on the inner side of the watch band assembly to collect real-time body surface temperature data of the wrist. The sensors are flexible temperature sensors based on organic thin film transistor technology, which have good flexibility and fit. The sensor's measurement range is 20℃-50℃, the resolution is 0.05℃, and the response time is less than 10s.

[0029] The watch band assembly has a millimeter-wave radar inside, which operates in the 24GHz band. It can transmit and receive millimeter-wave signals and detect human heart rate and respiratory rate signals through the Doppler effect. The radar has a detection range of 0-30cm and a resolution of 1cm, and can accurately detect the slightest movements of the human chest.

[0030] The monitoring module 11 has a low-power ARM Cortex-M4 processor, which is responsible for preprocessing the data collected by the sensor module, including filtering, amplification, analog-to-digital conversion, etc.

[0031] The sensor substrate is made of polyimide film, which has good flexibility, high temperature resistance and chemical stability. The sensor electrode is made of silver nanowire conductive film, which has high conductivity, high transparency and good flexibility, and can adapt to the bending and movement of the wrist.

[0032] The specific installation operation of the monitoring module 11 is as follows: Place the monitoring module 11 between the left watch band 1 and the right watch band 4, then press the button 5, and finally align the docking ends of the left watch band 1 and the right watch band 4. Push gently until the docking rod 2 is fully inserted into the telescopic groove of the right watch band 4. The internal push spring 3 is compressed and stores elastic potential energy. The positioning blocks 10 on both sides of the monitoring module 11 automatically embed into the positioning groove 13 on the inner wall of the cavity. Then release the button 5. The linkage rod 6 returns to its original position under the elastic force of the return spring 7, driving the locking pin 8 to be embedded in the lock hole 9, forming a stable closed loop structure of the watch band.

[0033] Disassembly of monitoring module 11: Press button 5 on the outside of right strap 4. Link rod 6 overcomes the resistance of reset spring 7 and slides along the track of sliding groove 12, causing locking pin 8 to completely disengage from locking hole 9 of positioning block 10. At this time, the locking state between monitoring module 11 and strap assembly is released. Then, docking rod 2 releases the stored elasticity due to push spring 3 and quickly slides out of telescopic groove. Left strap 1 and right strap 4 automatically spring open to both sides under the action of spring force to form a removal opening. Remove monitoring module 11. No additional tools are required during disassembly; it can be achieved by pressing with one finger.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
