detailed description

In order to make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments These are part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

An embodiment of the present application provides a wearable device for pulse detection, which can be used to detect a pulse at a user's wrist. The wearable device includes a device body and a fixing component, wherein the fixing component is used to fix the device body to a position of a wrist artery of a user. For example, the fixing component may be various types of wristbands. The device body is fastened to the user's wrist. The device main body includes a sensor 110, a processing device 120, an output device 130, and a protective case, and the sensor 110, the processing device 120, and the output device 130 are installed in the protective case to protect these components. FIG. 1 shows a topology relationship of each component of the main body of the device. The sensor 110 is connected to the processing device 120, and the processing device 120 is connected to the output device 130.

The sensor 110 is configured to contact the position of a wrist artery of a user, detect pulse information of the artery, and send the pulse information to the processing device. The number and position of the sensors can be set according to the actual detection mode and the requirements of detection accuracy. For example, the number of sensors can be set to one, two, or more than three. In order to achieve a more accurate detection effect, the number of the sensors can be set to three, which are sequentially arranged along the wrist artery extension direction, corresponding to the inch, ruler, and off positions, respectively, to simulate the doctor's use of three fingers to measure the inch, The perception of pulse at the ruler and off position. In an actual scenario, the sensor may be a dedicated sensor for measuring a pulse, or may be a miniature pressure sensor.

The processing device 120 is configured to generate waveform information of a pulse according to the pulse information, and sends the waveform information of the pulse to an output device. The output device 130 is configured to display a waveform information of the pulse to a user. The pulse information collected by the sensor is generally an analog signal, so the processing device needs to convert the analog signal into a digital signal, and at the same time, it can also perform some filtering, amplification, and other processing, so that the generated waveform information can more accurately reflect the pulse The actual situation. For example, the processing device 120 may include multiple processing circuits, namely an A / D conversion circuit, a filter circuit, and a signal amplification circuit. The A / D conversion circuit receives an analog signal (pulse information) sent by a sensor, and converts the analog signal. Is a digital signal, and then the digital signal is filtered and amplified by a filter circuit and a signal amplification circuit to generate a final digital signal (waveform information). If three sensors are provided, the processing device 120 may include three sets of A / D conversion circuits, filter circuits, and signal amplification circuits, which respectively process the pulse information collected by the three sensors to generate waveform information of the three pulses. For output device display. Alternatively, the processing device 120 may further be provided with a processor for fusing three waveform information, for performing data fusion on the three waveform information, and merging into one fused waveform information for the output device to display to the user .

The output device 130 is used to display the waveform information of the pulse to a user, so that the user can intuitively obtain the waveform information. In actual scenes, the specific way of display can be achieved through visual, auditory and other methods. For example, the output device may be an image output device, such as various types of display screens. The image output device displays a waveform chart corresponding to the waveform information of the pulse, and the user can obtain the current pulse condition by viewing the waveform chart. . In an embodiment of the present application, the display screen may be a transflective liquid crystal display screen. Because the transflective liquid crystal display screen changes the original projection and reflection ratio through coating, so that its transmittance and reflectivity are between the reflective screen and the transmissive screen, so whether the backlight is used or the backlight is turned off, It can clearly display the waveform diagram displayed on the screen, so that the user has a good experience.

In addition, the output device may also be an audio output device, such as a speaker or a headset. The audio output device plays the pulse sound of the waveform information of the pulse. At this time, the user can also intuitively know the current pulse condition. Currently, two output modes can be combined in an actual scene, that is, displaying a waveform chart and playing a pulse sound through an image output device and an audio output device at the same time.

Therefore, it is only necessary to wear the wearable device on the wrist during use, which is convenient to use, and can eliminate the need for the user to have relevant knowledge of Chinese medicine, and even ordinary users without professional knowledge can intuitively obtain the pulse. The waveform information accurately judges the pulse, which improves the applicability and convenience of pulse detection.

In some embodiments of the present application, the device main body may further include a driving device 140 disposed in the protective shell, a bottom cover of the protective shell is provided with a through hole, and the sensor It is sleeved to the driving device through the through hole, and the driving device is used to drive the sensor to freely enter and exit the protective shell, so that the sensor can contact or disengage with the user's wrist at a preset pressure. Schematic diagram of the topological relationship of each component in the device body in the example. In an actual scenario, the driving device may be a micro motor, and the power output part of the micro motor is connected to the sensor, which can change the position of the sensor, for example, make the sensor rise or fall. When the pulse detection is required, the sensor can descend with the user. By touching the wrist, you can control the pressure between the sensor and the user's wrist by controlling the distance of the fall, so as to simulate the different pulse cutting methods such as floating, middle, and sinking during the actual pulse cutting. When the pulse detection is over, the sensor can be controlled to rise and disengage from the user's wrist.

When the number of sensors is three, the driving device may be provided with three independent driving

units

141, 142, and 143, respectively corresponding to the three

sensors

111, 112, and 113, for individually driving each sensor to freely enter and exit the protective casing. , So that the pressure of each sensor in contact with the user's wrist can be controlled separately to achieve accurate simulation of the three-way nine-way pulse-cutting method in an actual scene, and the connection method is shown in FIG. 3.

In addition, the wearable device further includes a storage device for storing the waveform information of the pulse generated by the processing device, and the saved waveform information can be retrieved at any time, which is convenient for users to use in the subsequent diagnosis process. For example, if the user performs pulse measurement through the wearable device, because he does not have the professional knowledge of traditional Chinese medicine, he cannot judge his own physiological state through the displayed waveform chart. The waveform information of the pulse can be saved in the storage device, Professionals can call the saved data for analysis at any time.

Further, in order to facilitate the use of users without professional knowledge, the processing device may also match the waveform information of the generated pulse with preset sample waveform information, and obtain sample waveform information that matches the waveform information of the pulse, where: The sample waveform information refers to typical waveforms in various abnormal physiological states, and may be stored in a storage device in advance, and when needed, the processing device calls and matches the currently detected waveform information.
