Description

Technical Field

[0001] This invention relates to the field of health monitoring technology, and in particular to a multimodal day and night monitoring and early warning device. Background Technology

[0002] Circadian rhythms are an important reflection of a user's physiological state, including the periodic characteristics of physiological activities such as sleep, body temperature, and heart rate. Analyzing circadian rhythms can identify a user's normal or abnormal state. In medical institutions, daily shift work often involves three shifts, and long-term shift work can easily disrupt circadian rhythms, leading to sleep disorders, fatigue accumulation, and ultimately affecting work quality. Currently, domestic medical institutions primarily rely on indirect management systems to ensure the circadian rhythms of on-call staff, with very little direct monitoring of physiological indicators. Circadian rhythms can be regulated through scientific scheduling, mandatory rest and compensatory leave, and health intervention support.

[0003] Conventional wearable devices, such as smartwatches, smart bracelets, and fitness trackers, can monitor heart rate, exercise duration, and sleep duration; however, they monitor limited parameters and lack a strong correlation with circadian rhythms, thus failing to accurately represent them. In contrast, the latest wearable devices can perform biochemical sweat analysis based on body fluid analysis sensor platforms, enabling multi-modal sensing analysis. For example, in sweat sensing, analyzing Na+... + NH4 + K + It can detect lactic acid, glucose, and uric acid, and combine these with biophysical measurements such as temperature and pulse; among them, changes in cortisol in sweat vary with rhythm and can be used to characterize rhythm.

[0004] However, due to individual differences and specific needs, these interventions still cannot fundamentally solve the problem. Existing monitoring equipment is based on clinical gold standard monitoring methods, which require frequent sampling and are not portable; general smartwatches only monitor sleep duration and do not collect data on body temperature and respiratory rhythm, ignoring phase markers such as core body temperature and respiratory rhythm, making it difficult to achieve reliable evaluation and unable to effectively regulate circadian rhythms. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a multimodal day and night monitoring and early warning device that can solve the problem that traditional monitoring does not collect body temperature and rhythm data, ignores phase markers such as core body temperature and rhythm, and makes it difficult to achieve reliable evaluation.

[0006] The present invention solves the above-mentioned technical problems through the following technical means:

[0007] A multimodal day and night monitoring and early warning device includes a strap, a multimodal monitoring unit, and a body temperature monitoring unit for monitoring the user's body temperature. The multimodal monitoring unit is worn on the user's wrist via the strap.

[0008] The outer surface of the binding strip is provided with a first mounting groove and the inner surface is provided with a third mounting groove, and the first mounting groove and the third mounting groove are connected through a second mounting groove;

[0009] The multi-mode monitoring unit includes a mounting frame, a first detection patch, and a second detection patch; the mounting frame is embedded in a second mounting groove, the first detection patch is rotatably mounted in the first mounting groove, and the second detection patch is mounted in a third mounting groove.

[0010] A control ring is mounted on the outer surface of one end of the mounting frame that extends into the first mounting groove. The control ring is coaxially mounted with the first detection patch. A first transmission component is mounted on the middle of the surface of the second detection patch on the same side as the outer surface of the binding strip. A second transmission component is mounted on the mounting frame along the inner wall of the second mounting groove. The control ring is coupled with the first and second transmission components. When the user presses the first detection patch to detect sweat, the control ring drives the second detection patch to move at least partially to the outside of the third mounting groove through the first transmission component and abut against the user's cun-kou pulse position. The control ring then uses the second transmission component to make the second detection patch adhere to the user's wrist for pulse detection.

[0011] Through the above structural design, when detecting and regulating the user's circadian rhythm, not only can effective body temperature data be obtained, but also the changes in the rhythm can be analyzed based on the monitoring of cortisol in sweat and the changes in the monitored cortisol. At the same time, it is possible to flexibly choose whether to collect optical pulse sensor data as needed, which is flexible in use, low in power consumption and long in battery life.

[0012] Furthermore, the outer surface of the binding strip is provided with a control hole, which communicates with the second mounting groove. A control button is slidably installed in the control hole, and a locking piece is fixedly connected to the inner side of the control button. A limiting notch is connected to the outer surface of the end of the second detection patch away from the first mounting groove. Sliding the control button causes the locking piece to be locked in the limiting notch.

[0013] With the above structural design, after the second detection patch is attached by selecting the control ring, it can be positioned by the locking piece without maintaining the force applied by the rotating control ring, which is convenient and quick.

[0014] Furthermore, an elastic abutment is provided between the mounting frame and the locking piece to elastically support the locking piece and limit the locking piece from moving back after locking.

[0015] Through the above structural design, whether in the normal wearing state without optical pulse detection or when the second detection patch moves out of the third mounting slot and fits against the wrist during optical pulse detection, the locking piece can stably limit the position of the limiting notch and the second detection patch. To release the limiting position, simply slide the control button.

[0016] Furthermore, the inner surface of one end of the mounting frame that extends into the first mounting groove has an insertion port, and the outer surface of the second detection patch near the first mounting groove is connected to an inverted L-shaped hanging piece; a snap-fit ​​piece connects the insertion port and the inverted L-shaped hanging piece.

[0017] The above structural design allows for convenient installation of the snap-fit ​​tab and limits one end of the second detection patch. Combined with the limiting notch and the locking tab, the other end of the second detection patch is also limited, achieving stable and reliable fixation. Simultaneously, the third mounting slot also effectively limits the second detection patch. Furthermore, the snap-fit ​​tab can be bent and has minimal displacement along the length of the mounting frame, thus providing a degree of flexibility when the device is worn on the user's wrist.

[0018] Furthermore, a central limiting ring is provided in the middle of the snap-fit ​​piece, and a first battery for powering the first detection patch is installed between the first detection patch and the bottom wall of the first mounting groove. Two opposing orbiting rings are fixedly connected to the inner surface of the first battery. The two orbiting rings are arranged around the central limiting ring, and limiting pieces are provided on the inner surfaces of the two orbiting rings and the central limiting ring.

[0019] The above structural design allows the snap-fit ​​tab to limit and fix the first detection patch, preventing it from detaching from the first mounting slot; and it does not affect the rotation of the first detection patch and the control ring, ensuring the normal operation of the control ring. It should be noted that the rotation angle of the control ring is set to 0-15°.

[0020] Furthermore, the first transmission component includes a driven wheel and a shaped collar.

[0021] The inner surface of the binding strip is provided with a first limiting groove, which is located in the second mounting groove; the passive wheel is installed in the first limiting groove, and the outer peripheral wall of the control ring is provided with a contact helical tooth portion that couples with the passive wheel;

[0022] The inner surface of the passive wheel is fixed with a shaped collar, which has a height difference relative to one end face of the second detection patch. The surfaces of the second detection patch and the shaped collar are provided with oblique contact surfaces.

[0023] Furthermore, the second transmission component includes a semi-circular wheel, a transmission plate, a spring plate, and a pressure block;

[0024] The semi-circular wheel is mounted on the outer surface of one end of the mounting frame that extends into the first mounting groove, and the semi-circular wheel is coupled to the control ring.

[0025] The transmission plate and the pressure block are slidably connected to the mounting frame. One end of the transmission plate is connected to the end of the semi-circular wheel, and the other end is connected to the pressure block.

[0026] The inner wall of the mounting frame is provided with a fourth mounting groove, the spring sheet is disposed in the fourth mounting groove, and the two ends of the spring sheet are connected to the second detection patch;

[0027] When the control ring rotates, it drives the pressure block to slide through the transmission plate. The pressure block presses down on the spring plate, causing the second detection patch to undergo flexible deformation.

[0028] Furthermore, the spring sheet has a symmetrical conical structure, and the bottom wall of the pressure block is provided with a conical contact surface, which abuts against the tip of the spring sheet.

[0029] Furthermore, the body temperature monitoring unit is an ear temperature sensor and / or an infrared temperature sensor.

[0030] Furthermore, the multi-mode monitoring unit also includes a respiratory parameter detection unit, which is communicatively connected to a cloud server. The cloud server is used to obtain the user's respiratory parameters through the respiratory parameter detection unit and the user's body temperature parameters through the body temperature monitoring unit, and to establish the user's body temperature-respiratory coupling coefficient.

[0031] The infrared temperature sensor can be installed on the binding strap or on the inner surface of the first mounting slot, with an opening on the inner surface of the first mounting slot to allow the infrared rays from the sensor to illuminate the wrist. The ear temperature sensor can be set independently; it supports establishing the user's body temperature-respiratory coupling coefficient on a cloud server; it analyzes the user's diurnal rhythm changes based on the body temperature-respiratory coupling coefficient, and provides warnings and adjustments when the diurnal rhythm changes exceed the normal range.

[0032] The beneficial effects of this invention are:

[0033] 1. Body temperature can be monitored independently through the body temperature monitoring unit, while the first and second detection patches are idle, effectively extending standby time and ensuring long battery life; it can better achieve 72-hour circadian rhythm monitoring;

[0034] 2. Multi-mode monitoring can be performed through the body temperature monitoring unit and the first detection patch to establish the user's body temperature-respiration coupling coefficient; the detection linkage between the first and second detection patches can also be used to monitor more data.

[0035] 3. During use, pressing the first detection patch on the control ring allows for the collection and biochemical analysis of sweat. The analysis examines changes in cortisol levels and, based on the relationship between cortisol and circadian rhythm changes, identifies these rhythm variations, enabling early warning and regulation to help users perform their work more effectively. During sweat detection, the control ring can be rotated at any time, causing it to drive the second detection patch, via the first and second transmission components, to adhere to the corresponding area on the wrist for optical pulse sensing. This allows for pulse data analysis and aids in the monitoring of circadian rhythms. Attached Figure Description

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

[0047] First, it should be noted that this application can be used on any limb of the human body, not just the wrist, but also on other parts such as the legs. This application's embodiments only demonstrate the specific content of health monitoring on the wrist; by simply replacing the content of the selected target wearing area, the content for wearing in other locations can be derived, and will not be repeated here.

[0048] like Figures 1-8As shown, a multimodal day and night monitoring and early warning device of the present invention includes a strap 100, a multimodal monitoring unit 300, and a body temperature monitoring unit for monitoring the user's body temperature. The multimodal monitoring unit 300 is worn on the user's wrist via the strap 100. The outer surface of the strap 100 is provided with a first mounting groove 101, and the inner surface is provided with a third mounting groove 104. The first mounting groove 101 and the third mounting groove 104 are offset and connected to each other via a second mounting groove 103. The second mounting groove 103 is formed between the inner and outer surfaces of the strap 100. The multimodal monitoring unit 300 includes a mounting frame 301, a first detection patch 302, and a second detection patch. The mounting frame 301 is embedded in the second mounting groove 103, and the first detection patch 302 is rotatably mounted in the first mounting groove. Inside the first mounting groove 101; the second detection patch is installed inside the third mounting groove 104; a control ring 305 is installed on the outer surface of one end of the mounting frame 301 that extends into the first mounting groove 101, and the control ring 305 is coaxially installed with the first detection patch 302; a first transmission component is installed in the middle of the surface of the second detection patch on the same side as the outer surface of the binding strap 100, and a second transmission component is installed on the mounting frame 301 along the inner wall of the second mounting groove 103; the control ring 305 is coupled with the first transmission component and the second transmission component; when the user presses the first detection patch 302 to perform sweat detection, the control ring 305 drives the second detection patch to move at least partially to the outside of the third mounting groove 104 through the first transmission component and abut against the user's cun-kou pulse position; the control ring 305 causes the second detection patch to undergo flexible deformation and fit against the user's wrist through the second transmission component to perform pulse detection. In fact, the first detection patch 302 can employ a sweat sensor, utilizing the cortisol receptor recognition mechanism to analyze changes in cortisol in sweat. Based on the correlation between cortisol and rhythm changes, it can determine rhythm changes. This facilitates remote health management because sweat is easily obtained and carries a low risk of contamination. Furthermore, sweat can be easily collected through strenuous exercise or heat stress, and analysis can be performed on sweat at rest, especially the natural secretions from the fingertips. The sweat sensor is a sweat-sensing patch; any fingertip can be placed on the patch for sweat collection and detection. It is then cured into a control ring 305 with resin, and a rechargeable lithium battery is fixedly attached to the back of the patch; the lithium battery is charged using a wireless electromagnetic coil. The second detection patch can be a flexible optical pulse sensing patch 303. Correspondingly, the mounting frame 301 is made of a shape-memory metal material, such as nickel-titanium alloy, which can deform synchronously with the flexible optical pulse sensing patch 303 when it is attached to the wrist and can recover its original shape.Through the above structural design, when detecting and regulating a user's circadian rhythm, not only can effective body temperature data be obtained, but also changes in the rhythm can be analyzed based on the monitoring of cortisol in sweat and the changes in its monitoring. Simultaneously, the acquisition of optical pulse sensor data can be flexibly selected as needed, offering flexibility, low power consumption, and long battery life. Specifically, the flexible optical pulse sensor patch 303 is stored in the third mounting slot 104 during standby, avoiding contact with the skin and improving user comfort. During detection, the triggering of the flexible optical pulse sensor patch 303 can be set through body temperature monitoring; when the detected body temperature exceeds the normal value, a detection signal is sent to control the activation of the sweat sensor patch and the flexible optical pulse sensor patch 303.

[0049] In this embodiment, the flexible optical pulse sensing patch 303 features a monolithically integrated gallium nitride (GaN) optoelectronic chip and a micro / nanostructured PDMS thin film, supported by a data processing algorithm utilizing transfer learning. Inspired by the traditional Chinese medicine pulse diagnosis method of "cun, guan, chi," three identical sensing units are mounted on a flexible substrate to capture multiple pulse signals from the radial artery. Furthermore, for blood pressure data fitting, a one-dimensional convolutional neural network (1D-CNN), long short-term memory (LSTM), and wavelet transform (WT) combined with transfer learning (TL) are used, enabling accurate blood pressure monitoring for new users without extensive calibration. A control hole 102 is provided on the outer surface of the binding strap 100. The control hole 102 communicates with the second mounting groove 103. A control button 320 is slidably installed in the control hole 102. A locking piece 321 is fixedly connected to the inner side of the control button 320. A limiting notch 308 is connected to the outer surface of the end of the second detection patch, i.e., the flexible optical pulse sensing patch 303, away from the first mounting groove 101. Sliding the control button 320 causes the locking piece 321 to lock into the limiting notch 308. In order to prevent the control button 320 from falling out, a second limiting groove 107 can be opened inside the control hole 102. An anti-detachment piece is integrally fixed to the control button 320. Through the cooperation of the anti-detachment piece and the second limiting groove 107, the control button 320 can not fall out while still sliding, so that the control button 320 can drive the locking piece 321 to limit the limiting notch 308, and slide in the opposite direction to release the limit. With the above structural design, after the flexible optical pulse sensing patch 303 is attached to the control ring 305, it can be locked in place by the locking piece 321 without maintaining force on the rotating control ring 305, making it convenient and quick. To make the user more comfortable when detecting sweat, without maintaining force on the rotating control ring 305, an elastic abutment 313 can be provided between the mounting frame 301 and the locking piece 321 to elastically support the locking piece 321 and limit its return after locking. In this way, whether in the normal wearing state when not performing optical pulse detection, or when performing optical pulse detection and the second detection patch moves out of the third mounting slot 104 and fits against the wrist, the locking piece 321 can be stably limited in place by the limiting notch 308 and the second detection patch. When it is necessary to release the limit, the control button 320 can be slid.

[0050] In this embodiment, if the device is worn on the wrist, it can be a smart bracelet. A smart monitoring unit 200 can be installed on the strap 100 corresponding to the back of the hand to monitor the user's body temperature, heart rate, blood oxygen, etc. The smart monitoring unit 200 can be selected from commonly available smart bracelets. In fact, the multi-mode monitoring unit 300 may also include an ear temperature sensor and a respiratory rhythm sensor for monitoring core body temperature and respiratory rhythm. On one hand, it can work in conjunction with the smart monitoring unit 200 to perform mutual data calibration and compensation. The ear temperature sensor can be a zero-heat-flow ear canal sensor, and the respiratory rhythm sensor can be a chest strap-type ultrasonic Doppler array. In addition, an environmental synchronizer can be selected to acquire environmental parameters, such as using a Bluetooth beacon to record light / noise intensity. On the other hand, by coordinating the data acquired by the ear temperature sensor and the respiratory rhythm sensor, a body temperature-respiratory rhythm coupling coefficient can be set, and based on this, diurnal respiratory rhythm monitoring and adjustment can be performed.

[0051] In this embodiment, the first mounting groove 101 is circular, and the second mounting groove 103 is rectangular. The shape of the third mounting groove 104 is set according to the shape of the second detection patch. A connecting flap 304 is integrally provided at one end of the mounting frame 301 that extends into the first mounting groove 101. A limiting ring is fixedly connected to the connecting flap 304. The limiting ring is engaged with the middle of the outer peripheral surface of the control ring 305, so that the control ring 305 can rotate while being constrained in the first mounting groove 101, and can move toward the inner surface of the binding strap 100. When the first detection patch 302 is pressed, the inner end of the control ring 305 can contact the first transmission member and the second transmission member, and when the pressing of the first detection patch 302 is released, it disengages from the contact with the first transmission member and the second transmission member. In this way, the coupling between the control ring 305 and the first transmission member and the second transmission member is realized. To facilitate the removal of the second detection patch from the third mounting slot 104, a transition port 105 can be provided at the connection between the second mounting slot 103 and the third mounting slot 104; the transition port 105 is an inclined surface sloping towards the third mounting slot 104. A battery 322 is installed at the end of the second mounting slot 103 away from the first mounting slot 101, and the battery 322 supplies power to the second detection patch. In practice, a spring is fixed to the limiting ring, and the free end of the spring abuts against the control ring 305, providing elastic force so that the control ring 305 has the potential energy to release the pressure.

[0052] In fact, for convenient disassembly and installation of this device, an insertion port 317 is provided on the inner surface of the end of the mounting frame 301 that extends into the first mounting groove 101. An inverted L-shaped hanging piece 310 is connected to the outer surface of the end of the second detection patch near the first mounting groove 101. A snap-fit ​​piece 314 connects the insertion port 317 and the inverted L-shaped hanging piece 310. In this way, the snap-fit ​​piece 314 can be easily installed, and one end of the second detection patch is limited by the snap-fit ​​piece 314. In conjunction with the limiting notch 308 and the locking piece 321, the other end of the second detection patch is limited, achieving stable and reliable fixation. In addition, the snap-fit ​​piece 314 can slide in the insertion port 317 to adapt to the bending of the binding strap 100 when worn, providing good comfort and high flexibility. At the same time, the third mounting groove 104 can also effectively limit the second detection patch. Furthermore, the snap-fit ​​tab 314 can be bent and has a small displacement along the length of the mounting frame 301, thus providing a certain degree of flexibility when the device is worn on the user's wrist. In fact, a central limiting ring 3142 is provided in the middle of the snap-fit ​​tab 314, and a forked clip 3141 is provided at one end of the snap-fit ​​tab 314 near the third mounting groove 104. The forked clip 3141 is inserted into the inverted L-shaped hanging piece 310 and is limited by a fixed pin. A first battery (or lithium battery) for powering the first detection patch 302 is installed between the first detection patch 302 and the bottom wall of the first mounting groove 101. Two opposing revolution rings 316 are fixedly connected to the inner surface of the first battery. The two revolution rings 316 are arranged around the central limiting ring 3142, and limiting pieces 315 are provided on the inner surfaces of the two revolution rings 316 and the central limiting ring 3142. The two revolution rings 316 can rotate around the central limiting ring 3142, with a small rotation angle. After the binding strap 100 is worn, the snap-fit ​​tab 314 can limit and fix the first detection patch 302, preventing the first detection patch 302 from falling out of the first mounting slot 101; and it does not affect the rotation of the first detection patch 302 and the control ring 305, allowing the control ring 305 to operate normally. It should be noted that the rotation angle of the control ring 305 can be set from 0 to 15°. A spring can be provided between the central limiting ring 3142 and the first battery to release the coupling between the control ring 305 and the first transmission component.

[0053] In fact, to achieve miniaturization of this device, the second detection patch can share the power of the first detection patch 302. For example, the two orbital rings 316 can be configured as two electrical terminals, and the power of the lithium battery can be connected through the central limiting ring 3142 and the forked card 3141 to electrically connect to the second detection patch and supply power to the second detection patch.

[0054] In this embodiment, the first transmission component includes a passive wheel 309 and a shaped collar 323. A first limiting groove 106 is provided on the inner surface of the binding belt 100, and the first limiting groove 106 is located within the second mounting groove 103. The passive wheel 309 is mounted within the first limiting groove 106. The outer peripheral wall of the control ring 305 is provided with a contact helical tooth portion that couples with the passive wheel 309. The contact helical tooth portion is a smooth contact surface or a wheel surface with fine teeth. The shaped collar 323 is fixed to the inner surface of the passive wheel 309. The shaped collar 323 has a height difference relative to one end face of the second detection patch. The surface of the second detection patch corresponding to the shaped collar 323 is provided with an oblique contact surface. The second transmission component includes a semi-circular wheel 318, a transmission plate 306, a spring plate 307, and a pressure block 312. The semi-circular wheel 318 is mounted on the outer surface of one end of the mounting frame 301 that extends into the first mounting groove 101, and is coupled to the control ring 305. The transmission plate 306 and the pressure block 312 are slidably connected to the mounting frame 301. One end of the transmission plate 306 is connected to the end of the semi-circular wheel 318, and the other end is connected to the pressure block 312. The inner wall of the mounting frame 301 has a first... The fourth mounting slot 319 contains a spring plate 307, which is symmetrically shaped like a herringbone. The spring plate 307 is also herringbone shaped. Both ends of the spring plate 307 are connected to the second detection patch. When the control ring 305 rotates, the transmission plate 306 drives the pressure block 312 to slide, pressing down on the spring plate 307. This causes the second detection patch to deform flexibly and adhere to the wrist, simulating the pulse-taking technique used in traditional Chinese medicine. Alternatively, the spring plate 307 can also be a symmetrical conical structure, with a conical contact surface on the bottom wall of the pressure block 312 that abuts against the tip of the spring plate 307.

[0055] In fact, a double-hinged plate 311 connects the transmission plate 306 and the pressure block 312; the double-hinged plate 311 is hinged to both the transmission plate 306 and the pressure block 312, providing a high degree of rotational freedom. Since the bottom surface of the pressure block 312 is conical, it can press down on the spring plate 307 regardless of whether the pressure block 312 moves to the left or right. Conversely, the deformation of the spring plate 307 and the forked card 3141 will recover after the finger stops pressing.

[0056] In this embodiment, the body temperature monitoring unit is an infrared temperature sensor; it can be set in the intelligent monitoring body 200, or it can utilize the built-in configuration of the smart bracelet.

[0057] In fact, the multi-mode monitoring unit 300 also includes a respiratory parameter detection unit, which communicates with a cloud server. The cloud server is used to acquire the user's respiratory parameters through the respiratory parameter detection unit and the user's body temperature parameters through the body temperature monitoring unit, and to establish the user's body temperature-respiratory coupling coefficient. The infrared temperature sensor in the body temperature monitoring unit can be located on the binding strap 100 or on the inner surface of the first mounting slot 101, with an opening on the inner surface of the first mounting slot 101 to allow the infrared light from the infrared temperature sensor to illuminate the wrist. The ear temperature sensor can be set independently. It supports establishing the user's body temperature-respiratory coupling coefficient on the cloud server; it analyzes the user's diurnal rhythm changes based on the body temperature-respiratory coupling coefficient, and provides warnings and adjustments when the diurnal rhythm changes exceed the normal range. The respiratory parameter detection unit can use a chest strap-type ultrasonic Doppler array for respiratory rhythm monitoring, with a respiratory variability detection sensitivity of 0.1%.

[0058] The working principle of the multimodal day and night monitoring and early warning device in this embodiment is as follows:

[0059] Wearing the device on the wrist, if equipped with an intelligent monitoring unit 200, the intelligent monitoring unit 200 can be used to monitor the user's body temperature, heart rate, and blood oxygen; if equipped with an ear temperature sensor and a chest strap ultrasound Doppler array, body temperature can be detected through the ear temperature sensor; and respiratory rhythm can be monitored through the chest strap ultrasound Doppler array.

[0060] When abnormal body temperature or respiratory rhythm is detected, press your finger on the first detection patch 302, i.e., the sweat sensor patch, to collect sweat and analyze the cortisol in the sweat to infer changes in the diurnal rhythm.

[0061] When a finger presses onto the first detection patch 302, the control ring 305 presses down and contacts the outer surface of the passive wheel 309. At the same time, the inner end face of the control ring 305 can also contact the semi-circular wheel 318. The control ring 305 can be rotated. On the one hand, the passive wheel 309 and the irregular collar press down on the second detection patch (i.e., the flexible optical pulse sensing patch 303), so that the flexible optical pulse sensing patch 303 fits against the wrist. On the other hand, the transmission plate 306 drives the double hinge plate 311 and the pressure block 312 to move. The pressure block 312 moves and presses down on the spring plate 307. The bottom of both ends of the spring plate 307 bends the flexible optical pulse sensing patch 303, so that the flexible optical pulse sensing patch 303 fits better against the wrist.
