Abstract
Description
Technical Field
[0001] The utility model relates to an intelligent electronic wristband, in particular to an intelligent electronic wristband which can detect the vital signs of a user through pressure, including physiological indicators such as blood pressure and pulse. Background Art
[0002] With the development of science and technology, smartphones are widely used in users' daily lives. Users can use their various functions to improve the convenience of life, such as mobile payment, recording vital signs in daily life, etc. However, some situations in daily life are not conducive for users to carry smartphones to perform the above functions. For example, during exercise, the weight and size of the smartphone are not convenient for the user to carry, resulting in the user being unable to record the vital signs during exercise.
[0003] Therefore, a new type of wearable smart device is developed, which allows users to perform some functions of smart phones through wearable smart devices in specific situations. For example, because an electronic bracelet (wearable smart device) is lighter and smaller than a smart phone, the user can wear the electronic bracelet for a long time. Compared with a smart phone, the electronic bracelet can more completely record the physiological data of the user in daily life.
[0004] However, due to the limited size of the electronic wristband, the installation space of the physiological data sensor is limited, which in turn limits the types of physiological data sensors. For example, most electronic wristbands currently rely mainly on optical principles to realize their functions. An optical sensor is arranged on the inner surface of the existing electronic wristband. When a user wears the electronic wristband, the optical sensor will fit the user's skin to sense a light intensity signal reflected by the user's blood through optical principles, and then the light intensity signal is used to calculate a pulse data, a blood pressure data, a body temperature data, etc. through the processing device in the electronic wristband. If a plurality of physiological data are calculated only through the light intensity signal, the accuracy of some data (such as the pulse and the blood pressure data) will be questionable. Therefore, an improvement plan must be proposed to improve the accuracy of such physiological data measurement. Utility Model Content
[0005] Existing electronic bracelets usually use optical sensing principles to obtain the user's physiological data, which leads to concerns that some of the physiological data are insufficiently accurate. In view of this, the utility model proposes a pressure-sensitive smart electronic bracelet that uses physical sensing technology, namely pressure detection of the user's physiological data to improve the accuracy of obtaining and measuring physiological data such as blood pressure and pulse.
[0006] The pressure-sensitive smart electronic bracelet of the utility model comprises:
[0007] A first entity, comprising:
[0008] A first housing having a first side and a second side opposite to each other, the first side being connected to a wristband, and a first accommodating space being formed inside the first housing;
[0009] An air pump is disposed in the first accommodating space;
[0010] A second subject, comprising:
[0011] A second housing connected to the second side of the first housing and having a second accommodating space inside the second housing;
[0012] A control circuit board is disposed in the second accommodating space, and the control circuit board has a first surface and a second surface opposite to each other;
[0013] A plurality of pressure sensing groups, each of which includes a plurality of pressure sensors, which are disposed on the first surface of the control circuit board, and each of which is electrically connected to the control circuit board and has a contact portion, each of which is exposed on the outer surface of the second housing, and each of which senses the pulse of the user to generate a pressure sensing signal;
[0014] An air bag is arranged in the second accommodating space, and the air bag is located between the second surface of the control circuit board and the second shell and is connected to the air pump.
[0015] The pressure-sensitive smart electronic wristband of the utility model comprises a first body and a second body. Compared with the electronic wristband described in the background art, the space for setting the physical sensor is increased so that the types of physiological data measurement are not limited. When the user wears the pressure-sensitive smart electronic wristband, each pressure sensor transmits the user's pulse beat through the contact part to generate a pressure sensing signal; in addition, when the airbag is inflated, each contact part can protrude further from the second shell to increase the contact area and tightness with the user's skin; compared with the prior art that senses pulse data through optical principles, the transmitter (or receiver) of the optical sensor may be blocked by external objects, resulting in inaccurate sensed pulse data. The pressure-sensitive smart electronic wristband of the utility model measures the user's pulse data through contact conduction, which will effectively improve the accuracy of obtaining and measuring physiological data such as blood pressure and pulse.
[0016] The pressure-sensitive smart electronic bracelet has a unique physical sensing technology that can instantly detect the user's vital signs, including blood pressure, pulse and other physiological indicators, and the pressure-sensitive smart electronic bracelet transmits the obtained data to the AI server, and obtains multiple analysis results after in-depth analysis and calculation. These analysis results can be fed back to the user himself, and will also be provided to relevant medical institutions at the same time, so that medical staff can quickly understand the user's physiological state in order to provide effective medical treatment and suggestions.

[0031] In order to understand the technical features and practical effects of the utility model in detail and to realize the utility model according to the content of the new model, the embodiments shown in the figures are further described in detail as follows:
[0032] See also Figures 1 to 3 The pressure-sensitive smart electronic wristband 1 of the utility model comprises a first body 10, a second body 20 and a wristband 30. The first body 10 is connected to the second body 20 and the wristband 30 respectively. Specifically, the second body 20 and the wristband 30 are respectively connected to the opposite sides of the first body 10, and the wristband 30 is detachably connected to the second body 20. When the wristband 30 is connected to the second body 20, the pressure-sensitive smart electronic wristband 1 will be as follows. Figure 3 It is shown in a ring shape and can be worn by a user.
[0033] The first body 10 includes a first shell 11 and an air pump 12. The first shell 11 has a first side and a second side opposite to each other. The first side is connected to the bracelet 30, and the second side is connected to the second body 20. The first shell 11 has a first accommodating space (not shown) inside. The air pump 12 is arranged in the first accommodating space. Specifically, a channel 13 is formed on the first shell 11, and the channel 13 connects the first accommodating space with the outside of the first shell 11. When the air pump 12 is in operation, the gas outside the first shell 11 can be drawn through the channel 13 for inflation.
[0034] In one embodiment of the present invention, the first body 10 further includes at least one button 14, a screen 15, an optical sensor 16 and a first controller, wherein the first controller is electrically connected to the at least one button 14, the screen 15, the optical detector 16 and the air pump 12 respectively.
[0035] The at least one button 14 is disposed on the outer surface of the first housing 11. The at least one button 14 is operated by the user to execute the function of the pressure-sensitive smart electronic bracelet 1. For example, the user presses the at least one button 14 to start the air pump 12. The screen 15 is disposed in the first accommodation space, and a display surface of the screen 15 is exposed on the outer surface of the first housing 11. Preferably, the screen 15 is a touch display screen, and Figure 3 As shown, when the pressure-sensitive smart electronic bracelet 1 is worn on a wrist W of a user, the surface of the first shell 11 that contacts the user is defined as a user contact surface 110, and the screen 15 is exposed on the external surface opposite to the user contact surface 110, so that the user can perform touch operations to execute the functions of the pressure-sensitive smart electronic bracelet 1. For example, in addition to activating the air pump 12 by the at least one button 14 as mentioned above, the user can also activate the air pump 12 by touching the screen 15.
[0036] The optical sensor 16 is disposed in the first accommodation space, and a detection surface of the optical sensor 16 is exposed to the outer surface of the first housing 11. Specifically, the detection surface of the optical sensor 16 is exposed to the user contact surface 110. The optical sensor 16 emits light and receives reflected light through the detection surface to detect the user's physiological data. The first controller is disposed in the first accommodation space. For example, the first controller is a microcontroller (MCU).
[0037] The second body 20 includes a second housing 21, a control circuit board 22, an air bag 23 and a plurality of pressure sensing groups. The second housing 21 is connected to the second side of the first housing 11. Preferably, the second housing 21 and the first housing 11 are connected by a pivot connection. Figure 4 and Figure 5 The second housing 21 has a second accommodating space 210 inside, the control circuit board 22 is arranged in the second accommodating space 210, and the control circuit board 22 has a first surface 220 and a second surface 221 opposite to each other. The airbag 23 is arranged in the second accommodating space 210, and the airbag 23 is located between the second surface 221 of the control circuit board 22 and the second housing 21. The airbag 23 is connected to the air pump 12 and can change its volume according to the opening and closing state of the air pump 12.
[0038] For example, Figure 1 and Figure 2As shown, the airbag 23 is connected to the air pump 12 via a pipeline 230. When the air pump 12 is started, the gas drawn into the air pump 12 from the channel 13 will be filled into the airbag 23 through the pipeline 230, and the airbag 23 will be expanded accordingly. When the air pump 12 is started for a period of time and then turned off, the gas in the airbag 23 will be discharged from the air pump 12 or the channel 13 through the pipeline 230, and the airbag 23 will be restored to an uninflated state.
[0039] Each of the pressure sensing groups includes a plurality of pressure sensors 24, and the plurality of pressure sensors 24 are disposed on the first surface 220 of the control circuit board 22. Specifically, Figures 3 to 5 As shown, the outer surface of the second housing 21 includes an inner surface 211 and an outer surface 212, each of the pressure sensors 24 includes a contact portion 240 and a sensor body 241, the inner surface 211 exposes each of the contact portions 240, and each of the contact portions 240 is connected to each of the sensor bodies 241, and a ring band fixing portion 25 is provided on the outer surface 212, and the ring band fixing portion 25 is provided for the wristband 30 to be detachably connected. For example, the ring band fixing portion 25 is a watchband buckle, and the wristband 30 can pass through and be clamped on the watchband buckle to connect to the second body 20.
[0040] When the pressure-sensitive smart electronic bracelet 1 is worn on the wrist W of the user, each of the contact portions 240 contacts the surface of the wrist W, and the area of contact between each of the contact portions 240 and the user can increase or decrease according to the volume of the airbag 23. When the airbag 23 is inflated and expanded, the control circuit board 22 will be squeezed by the airbag 23 and move, thereby pushing the contact portion 240 further into the second accommodating space 210 (such as Figure 5 As shown in the figure, the area of the contact portion 240 exposed on the inner surface 211 will increase, the area of each contact portion 240 in contact with the user will increase, and because each contact portion 240 is pushed by the airbag 23, it can fit more closely to the surface of the wrist W.
[0041] See also Figure 6, each of the pressure sensors 24 is electrically connected to the control circuit board 22, and each of the pressure sensors 24 is used to sense the pulse of the user to generate a pressure sensing signal S1. Specifically, the control circuit board 22 is provided with a second controller 26, and the second controller 26 can also be a microcontroller. The second controller 26 is electrically connected to each of the pressure sensors 24, and preferably, the second controller 26 is electrically connected to the sensor body 241 of each of the pressure sensors 24. The pulse of the user can be transmitted to each of the sensor bodies 241 through each of the contact portions 240, and each of the sensor bodies 241 will transmit an analog signal to the second controller 26, and the analog signal is the pressure sensing signal S1. It should be particularly noted that when each contact portion 240 is pushed by the airbag 23 to fit more closely to the surface of the wrist W, the signal strength of the pressure sensing signal S1 generated by each pressure sensor 24 will be enhanced (compared to the uninflated state of the airbag 23).
[0042] In one embodiment of the present invention, the plurality of pressure sensors 24 are divided into a plurality of first pressure sensors and a plurality of second pressure sensors, each of the first pressure sensors transmits a first pressure sensing signal to the control circuit board 22, and each of the second pressure sensors transmits a second pressure sensing signal to the control circuit board 22, that is, each of the pressure sensing groups transmits the first pressure sensing signal and the second pressure sensing signal to the control circuit board 22 (second controller 26), respectively, and the control circuit board (second controller 26) calculates the difference between each of the first pressure sensing signals and each of the second pressure sensing signals to generate a plurality of pressure processing signals.
[0043] Specifically, each of the pressure sensing groups includes a first pressure sensor and a second pressure sensor, and the contact portion of each of the first pressure sensors and the contact portion of each of the second pressure sensors are respectively located on opposite sides of the inner surface 211. When the user wears the pressure-sensitive smart electronic bracelet 1, at least one of the multiple pressure sensing groups can correspond to the user's arterial position, and the contact portions of the first pressure sensor and the second pressure sensor of the pressure sensing group can also correspond to the user's arterial position.
[0044] The second controller 26 uses the smaller signal waveform amplitude of the first pressure sensing signal and the second pressure sensing signal of the pressure sensing group as a reference signal, and subtracts the reference signal from the other signal to generate a pressure processing signal. For example, if the signal waveform amplitude of the first pressure sensing signal of one of the pressure sensing groups is smaller, the second controller 26 uses the first pressure sensing signal as the reference signal, subtracts the first pressure sensing signal from the second pressure sensing signal of the pressure sensing group to generate the pressure processing signal. The second controller 26 will also calculate the respective pressure processing signals of the first pressure sensing signal and the second pressure sensing signal transmitted by other pressure sensing groups that do not correspond to the user's artery in this way. The difference is that the signal value of the pressure processing signal of the pressure sensing group corresponding to the user's artery is not zero, and the signal value of the pressure processing signal of the pressure sensing group that does not correspond to the user's artery is zero.
[0045] In one embodiment of the present invention, Figure 6 As shown, the second controller 26 is connected to the first controller 17 and a pressure sensor 27. The pressure sensor 27 is disposed in the second accommodation space 210. The pressure sensor 27 is used to sense the air pressure inside the airbag 23 to generate a pressure measurement signal S2 to the second controller 26. The second controller 26 transmits the pressure sensor 27 to the first controller 17, so that the first controller 17 controls the air pump 12 to be turned off according to the pressure measurement signal S2. For example, the first controller 17 is preset with a pressure threshold value. The first controller 17 determines whether the pressure value inside the airbag 23 is greater than the pressure threshold value according to the pressure measurement signal S2. If it is, it means that the airbag 23 is full of gas, and the first controller 17 controls the air pump 12 to be turned off to stop inflating the airbag 23.
[0046] In the present embodiment, the control circuit board 22 is further provided with at least one of a Bluetooth low energy module 28 (BLE) and a wireless network module 29 (Wi-Fi). The Bluetooth low energy module 28 and the wireless network module 29 are electrically connected to the second controller 26 respectively. The second controller 26 transmits the received pressure sensing signal S1 and the air pressure measurement signal S2 to the outside through at least one of the Bluetooth low energy module 28 and the wireless network module 29. For example, the second controller 26 can be connected to an AI server through the Bluetooth low energy module 28 or the wireless network module 29 to transmit the pressure sensing signal S1 and the air pressure measurement signal S2 to the AI server.
[0047] In one embodiment of the present invention, Figure 1As shown, the first body 10 includes at least one charging port 18, and the at least one charging port 18 is exposed on the outer surface of the first housing 11. In this embodiment, please refer to Figure 7 and Figure 8 The pressure-sensitive smart electronic wristband 1 can be used in conjunction with an electronic wristband charging cabinet 40. The electronic wristband charging cabinet 40 includes a cabinet 41, multiple charging posts 42, multiple warning lights 43 and multiple ultraviolet (UV) lamps 44. The cabinet 41 has at least one wristband setting space 410 inside. Each of the wristband setting spaces 410 is provided with a limiting bracket 411, multiple charging posts 42, multiple warning lights 43 and multiple ultraviolet (UV) lamps 44. The limiting bracket 411 includes multiple limiting notches 412, each of which is provided for a pressure-sensitive smart electronic wristband 1, and each of the limiting notches 412 is provided for a pressure-sensitive smart electronic wristband 1. The position of the limiting notch 412 corresponds to the position of a charging column 42 and the position of a warning light 43. Therefore, when the pressure-sensitive smart electronic wristband 1 is set in an electronic wristband charging cabinet 40, the at least one charging port 18 can be electrically connected to a charging column 42 for charging. For example, the at least one charging port 18 is magnetically adsorbed to each charging column 42, and the warning light 43 is used to remind the user of the charging status of the pressure-sensitive smart electronic wristband 1, and the multiple ultraviolet lamps 44 are used to emit ultraviolet light to irradiate the pressure-sensitive smart electronic wristband 1 set in the wristband setting space 410.
[0048] In another embodiment of the present invention, Figure 2 As shown, the first body 10 includes a near field communication tag 19 (NFC Tag), which is disposed in the first accommodation space. An identification information is established in the near field communication tag 19. The identification information may be, for example, a unique identification code (UID). In this embodiment, please refer to Fig. 9 The pressure-sensitive smart electronic wristband 1 can be used in conjunction with an identity pairing device 50. The identity pairing device 50 includes a housing 51, a touch screen 52, a card slot 53 and a wristband positioning slot 54. The touch screen 52, the card slot 53 and the wristband positioning slot 54 are arranged on the housing 51. The touch screen 52 can be operated by a user by touch. The card slot 53 can be used by a user to insert a personal identification document (e.g., a health insurance card). The wristband positioning slot 54 is used to set a pressure-sensitive smart electronic wristband 1, and then the pressure-sensitive smart electronic wristband 1 is worn at a specific position on the user's hand according to the user's operation. A near field communication reader 55 (NFC Reader) and a camera lens 56 are respectively arranged at the bottom and top of the wristband positioning slot 54. The near field communication reader 55 is used to read the near field communication tag 19 of each pressure-sensitive smart electronic wristband 1, and the camera lens 56 is used to photograph the internal space of the wristband positioning slot 54.
[0049] The application method of the pressure-sensitive smart electronic wristband 1 and the identity pairing device 50 is, in short, that the user can first insert his personal identity document into the card slot 53 to verify the identity of the user, and then set a pressure-sensitive smart electronic wristband 1 in the wristband positioning slot 54, the near-field communication reader 55 will read the identification information of the near-field communication tag 19, and the identity pairing device 50 will verify the identification information and pair the identification information with the identity of the user, and then the identity pairing device 50 will activate the camera lens 56 and display the information on the touch screen 52. The operation prompt information is displayed to prompt the user to put his hand into the wristband positioning groove 54, and the user can adjust the position of the hand through the touch screen 52 so that the specific position of the user's hand corresponds to the pressure-sensitive smart electronic wristband 1 to complete the positioning. Preferably, the pressure-sensitive smart electronic wristband 1 can be connected to the identity pairing device 50 through the aforementioned Bluetooth low energy module 28 or the wireless network module 29, and the user can operate the functions of the pressure-sensitive smart electronic wristband 1 on the identity pairing device 50, such as starting the air pump 12 to measure the user's physiological values.
[0050] In another embodiment of the present invention, the air pump 12 is connected to the control circuit board 22, and the control circuit board 22 is connected to a mobile device M (such as a mobile device M) having a shooting function through the Bluetooth low energy module 28 or the wireless network module 29. Fig.10 As shown), the mobile device M may be, for example, a smart phone, and the mobile device M is used to photograph the internal space of an auxiliary wear mold 60. Specifically, a first opening 61 is formed on the top of the auxiliary wear mold 60. The user can set the mobile device M on the top of the auxiliary wear mold 60 to photograph the internal space of the auxiliary wear mold 60 through the first opening 61.
[0051] The coordinated application method of the mobile device M, the pressure-sensitive smart electronic wristband 1 and the auxiliary wearing mold 60 is, in short, that the user can first execute an application software (APP) on the mobile device M, and must log in to the application software to confirm the user's identity, and then set a pressure-sensitive smart electronic wristband 1 in the auxiliary wearing mold 60, and then operate the application software to execute the shooting function of the mobile device M and display operation prompt information through the screen of the mobile device M, prompting the user to put his hand into the auxiliary wearing mold 60 and adjust the position of the hand through the touch screen 52, so that the specific position of the user's hand corresponds to the pressure-sensitive smart electronic wristband 1, and then the user can buckle the wristband strap 30 by himself to complete the wearing. Preferably, the user can operate the functions of the pressure-sensitive smart electronic wristband 1 through the mobile device M, for example, control the air pump 12 to be turned on or off through the mobile device M.
[0052] The pressure-sensitive smart electronic wristband 1 of the utility model can respectively execute a blood pressure measurement process and a pulse measurement process. First, the blood pressure measurement process is described, which includes the following steps:
[0053] 1. When the pressure-sensitive smart electronic wristband 1 is tied to a user's wrist, the air pump 12 of the pressure-sensitive smart electronic wristband 1 inflates the airbag 23 according to the user's operation; for example, as in the aforementioned embodiment, the user can start the air pump 12 through the at least one button 14 or the screen 15 to inflate the airbag 23, or the user can set the air pump 12 to automatically start through the at least one button 14 or the screen 15 to inflate the airbag 23.
[0054] 2. When the air pump 12 stops running to deflate the airbag 23, the control circuit board 22 receives the pressure sensing signal S1 transmitted by each pressure sensor 24 and performs multiple signal processing processes on each pressure sensing signal S1 to obtain a pulse amplitude signal; for example, as in the embodiment described above, the first controller 17 is connected to the control circuit board 22 and the air pump 12 and is preset with an air pressure threshold value. The first controller 17 determines whether the air pressure value inside the airbag 23 is greater than the air pressure threshold value based on the air pressure measurement signal S2. If it indicates that the airbag 23 is filled with gas, the first controller 17 controls the air pump 12 to turn off to stop inflating the airbag 23.
[0055] When the air pump 12 stops inflating the airbag 23, the airbag 23 will be deflated. During the deflation process of the airbag 23, a pressure change curve C1 in the airbag 23 will be as shown in FIG. Fig.11 As time goes by, the pressure sensor signal S1 gradually decreases, and during this process, the control circuit board 22 performs the multiple signal processing processes on each pressure sensing signal S1 to obtain the following signal: Fig.12 For a pulse amplitude signal C2 shown, the plurality of signal processing processes may include, for example, at least one signal filtering process and at least one signal amplification process.
[0056] 3. Such as Fig.13As shown, the control circuit board 22 (the pressure-sensitive smart electronic wristband 1) transmits the pulse amplitude signal to an AI server 70. The AI server 70 extracts a plurality of feature point information through in-depth analysis and calculation. The plurality of feature point information includes a systolic pressure information and a diastolic pressure information. For example, the AI server 70 includes a data transmission module 71, a computing module 72 and a database 73. The computing module 72 is connected to the data transmission module 71 and the database 73. The data transmission module 71 is used to receive the information transmitted by the pressure-sensitive smart electronic wristband 1 or to send information to the outside. The computing module 72 has a plurality of algorithms built in. The computing module 72 can analyze and calculate the signal transmitted by the pressure-sensitive smart electronic wristband 1. For example, Fig.14 As shown, the computing module 72 superimposes the air pressure variation curve C1 and the pulse amplitude signal C2 to obtain a plurality of intersections, which are the plurality of feature point information.
[0057] Alternatively, the computing module 72 can obtain multiple analysis results by deeply analyzing and calculating the signal transmitted by the pressure-sensitive smart electronic wristband 1, and then transmit the multiple analysis results to the pressure-sensitive smart electronic wristband 1 or a medical institution 80 through the data transmission module 71, so that the user himself or the medical staff in the medical institution 80 can understand the user's physiological state; the database 73 is used to record the information transmitted by the pressure-sensitive smart electronic wristband 1 or the information calculated by the computing module 72.
[0058] The steps of the pulse measurement process are partially the same as those of the blood pressure measurement process, but the difference is that when the inflation pump 12 stops running to deflate the airbag 23, the control circuit board 22 receives the pressure sensing signal S1 transmitted by each pressure sensor 24 and performs multiple signal processing processes on each pressure sensing signal S1 to obtain a pulse wave signal, and then performs Fourier transform on the pulse wave signal to obtain a high-frequency signal and a low-frequency signal, and then transmits the pulse wave signal, the high-frequency signal and the low-frequency signal to the AI server 70. The AI server 70 extracts multiple feature waveform information through deep analysis and calculation.
[0059] The pressure-sensitive smart electronic wristband 1 of the utility model comprises a first body 10 and a second body 20. Compared with the electronic wristband described in the background art, the space for setting the physical sensor is increased so that the types of physiological data measurement are not limited, and the second body 20 is provided with a plurality of pressure sensors 24, each of which has a contact portion 240. When the user wears the pressure-sensitive smart electronic wristband 1, each of the pressure sensors 24 transmits the user's pulse beats through the contact portion 240 to generate a pressure sensing signal; in addition, the second body 20 is provided with an air bag 23. When the air bag When the airbag 23 is inflated, each contact portion 240 can protrude further from the second body 20 to increase the contact area with the user's skin, and because of the pushing of the airbag 23, the close contact between each contact portion 240 and the user's skin is improved; compared with the background technology described in the present invention, which only senses pulse data through optical principles, and the transmitting end (or receiving end) of the optical sensor may be blocked by foreign objects, resulting in inaccurate sensed pulse data, the pressure-sensitive smart electronic bracelet 1 of the present invention measures the user's pulse data through physical contact conduction, which will effectively improve the accuracy of measuring physiological data such as blood pressure and pulse.
