Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a wearable blood pressure measuring device. Background Art

[0002] At present, blood pressure measuring devices have been widely used in personal health management and medical testing. These devices usually take the form of manual measurement or fixed electronic sphygmomanometers, relying on the user's active operation or regular measurement to obtain blood pressure data. In traditional devices, most are cuff-type designs, which collect data through air pump inflation and pressure sensor sensing. Although this method can more accurately reflect blood pressure conditions, its usage scenarios are often limited to fixed measurement environments, and users need to actively participate in the operation, which cannot meet the needs of continuous wearing and real-time monitoring. In addition, the functions of some devices in data interaction and abnormal situation processing are relatively simple, and it is difficult to adapt to the higher requirements of modern health management for real-time and intelligence.

[0003] However, with the increasing demand for personal health management, the convenience, intelligence and multi-functional support of blood pressure measurement devices are particularly important. Traditional blood pressure measurement equipment is usually based on cuff-type electronic sphygmomanometers, which collect blood pressure data through the cooperation of air pumps and pressure sensors. However, this type of equipment is mostly limited to manual operation or single measurement mode. Although it can provide a certain degree of measurement accuracy, it still has shortcomings in long-term monitoring and data real-time performance. In addition, most existing devices focus on the user's single measurement experience, lack flexible measurement frequency regulation and multi-party data sharing functions, especially in family health management, and fail to effectively meet the family's real-time grasp of the user's health status. Therefore, how to realize these functions to more efficiently meet user needs is an urgent problem to be solved in the current health monitoring field. Summary of the invention

[0017] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Please refer to the attached Figure 1 -Attached Figure 3 , an embodiment of the present invention provides a wearable blood pressure measurement device, comprising: A case 1, which serves as a protective shell and is used to carry major delicate components; A watch strap 3, which is installed on both sides of the watch case 1 and is used to assist the watch case 1 in binding; A connecting buckle 4 is installed between the watch straps 3 and is used to buckle the broken positions between the watch straps 3; A pressure sensor 5, which is mounted on the inner surface of the strap 3 and is used to measure the blood pressure value of the target artery through applanation scanning; A micro air pump 6 is installed inside the strap 3 and is used to inflate the strap 3 to make it expand and push the pressure sensor 5 to fit better; The control component is installed inside the watch case 1 and is used to control the micro air pump 6 and receive data measured by the pressure sensor 5 .

[0019] Specifically, in actual use, the user needs to wear the watch case 1 on the surface of the arm to ensure that the device is in the correct measurement posture. During operation, by aligning and connecting the straps 3 on both sides, the tightness of the strap is adjusted using the connecting buckle 4 so that it fits the arm and is adjusted to a comfortable and stable position to prepare for subsequent measurements. When blood pressure measurement is required, the micro air pump 6 will start and inflate the inside of the strap 3. As the gas gradually fills into the strap 3, the strap 3 expands and bulges due to its special elastic design, thereby generating a moderate squeezing force at the wearing position. This process ensures that the strap 3 can fully fit the surface of the arm and provide a stable environment for measurement. At the same time, the pressure sensor 5 installed on the side of the strap 3 that fits the skin will then be close to the user's skin surface. With this close fit, the pressure sensor 5 can efficiently sense the pressure changes at the wearing position, and accurately locate the target artery and measure the blood pressure value through applanation scanning technology. This design not only ensures the accuracy of the measurement, but also improves the user experience, making blood pressure monitoring more convenient and efficient.

[0020] The control component includes a PLC module 7, which is electrically connected to the micro air pump 6, and the PLC module 7 is electrically connected to the pressure sensor 5. A photoelectric volumetric pulse wave module 13 is arranged at the bottom of the PLC module 7 through the case 1. A screen display 2 is arranged on the top of the case 1, and the screen display 2 is electrically connected to the PLC module 7. A power supply module 8 is arranged inside the case 1, and the power supply module 8 is electrically connected to the PLC module 7. A transmission module 9 is arranged inside the case 1, and the transmission module 9 is electrically connected to the PLC module 7. An audio module 10 is arranged inside the case 1, and the audio module 10 is electrically connected to the PLC module 7. An emergency module 11 is arranged inside the case 1, and the emergency module 11 is electrically connected to the PLC module 7. Knobs 12 are arranged on both sides of the case 1, and the knobs 12 are used to directly control the switching state of the micro air pump 6 through the PLC module 7.

[0021] Specifically, when the pressure sensor 5 successfully measures the user's blood pressure value, the collected data signal will be directly sent to the PLC module 7 through the network transmission function. After receiving the data, the PLC module 7 quickly processes it and transmits it to the screen display 2, and intuitively displays the restricted and optimized blood pressure measurement results on the screen display 2, which is convenient for users or caregivers to quickly understand the situation. At the same time, the power supply module 8, as the battery component at the core of the device, stably provides power support for the entire system to ensure the normal operation of all parts of the device. In particular, the power supply of the pressure sensor 5 and the micro air pump 6 is achieved through the clever wiring layout inside the strap 3, which not only ensures the stability of the power supply, but also avoids the interference of external cables, improves the user's wearing comfort and the overall reliability of the device, and the PLC module 7 can detect the ratio of oxygenated hemoglobin and deoxygenated hemoglobin by cooperating with the photoelectric volumetric pulse wave module 13 set therewith, so as to accurately obtain the blood oxygen saturation value.

[0022] Furthermore, the amplitude and period of the change of the chest blood flow are detected by the respiratory modulation component in the signal sent by the photoplethysmography module 13, and the respiratory frequency can be measured through the following steps to monitor the respiratory state: A. Collecting the signal emitted by the photoplethysmography module 13 → filtering (denoising, extracting low-frequency components); B. Extract respiration-related features (PAM, PIM, baseline drift); C. Perform spectrum analysis (FFT / DWT) in the frequency domain to extract the respiratory frequency; D. Verify the frequency results in the time domain by peak-to-valley detection or zero-crossing detection; E. Fuse multiple feature results and smoothly output the final respiratory rate value.

[0023] The photoplethysmography module 13 can also directly extract the heart rate value through the pulse waveform, and identify the heart rhythm state by analyzing the regularity of the waveform, such as whether there is an abnormal condition such as arrhythmia.

[0024] In this way, breathing, heart rate and blood oxygen are combined to analyze the sleep state, such as deep sleep, light sleep and wakefulness.

[0025] In order to further expand the functionality, the transmission module 9 is used to wirelessly transmit the measured data to the supporting collection APP on the mobile phone. This design not only makes it convenient for users to view historical records, but also enables family members to understand the user's blood pressure status in real time. It is especially suitable for elderly users or patients with chronic diseases who need long-term monitoring. In addition, the integration of the audio module 10 is designed for the aging group. It can intuitively inform the user of the current blood pressure value through the voice broadcast function, and make a preliminary assessment of their health status, such as reminding "your blood pressure is high" and making suggestions for improvement. This considerate voice function greatly reduces the reading barriers of elderly users to the data on the screen 2, and improves the usability and convenience of the device. At the same time, the enable and disable status of the audio module 10 can be flexibly controlled by the PLC module 7, and can be freely selected according to user needs.

[0026] In more severe situations, such as when a user's blood pressure value is detected to be seriously abnormal, the emergency module 11 will be activated immediately and quickly send an alarm notification to the preset emergency contact through the network. This emergency handling mechanism can buy valuable time for users in critical moments, thereby greatly improving the safety and reliability of the equipment. In addition, the PLC module 7 provides a touch screen interactive function, and the user or his family can set the timed measurement function in advance through the screen display 2 to ensure that the user can monitor blood pressure regularly. In order to avoid the discomfort of elderly users caused by sudden measurements, the audio module 10 will give a gentle time reminder before the measurement to remind the user that the measurement state is about to be entered, further improving the friendliness of the user experience.

[0027] Considering possible special situations, such as when the user cannot touch the screen due to an emergency or personal inconvenience, the device is also designed with a knob 12, so that the user can quickly terminate the current measurement process and restore the device to standby mode by rotating the knob 12. This design fully considers the needs of elderly users and special situations, which not only ensures safety during use, but also reflects the humanization concept of the device. This whole set of design solutions ensures the convenience of user operation and the accuracy of data acquisition, while also providing family members with an effective means of real-time attention and emergency response.

[0028] Working principle: When in use, the user places the watch case 1 on the upper surface of the arm, and then aligns the straps 3 on both sides together, and uses the connecting buckle 4 to adjust the tightness between the straps 3 to a comfortable level. Then, when blood pressure needs to be measured, the inside of the strap 3 is inflated by the micro air pump 6. At this time, the strap 3 is inflated by gas due to its elasticity. At this time, the user will feel the squeezing force at the wearing position, and the pressure sensor 5 set on the side of the strap 3 that fits the user's skin will also fit the user's skin because of the bulging of the strap 3. In this way, the pressure sensor 5 can press the position of the artery, so as to measure the blood pressure value through conventional pressure. After the blood pressure value is measured by the pressure sensor 5, it will be transmitted to the position of the PLC module 7 through the network signal. At this time, after the PLC module 7 receives the data, it will be transmitted to the position of the screen 2 to limit the data. The power supply module 8 is a battery component for power supply, which can supply power to all the structures of the device as a whole. The power supply of the pressure sensor 5 and the micro air pump 6 is realized through the internal wiring of the strap 3. The transmission module 9 is used to The measured data is transmitted to the collection APP, which is convenient for other people at home to pay attention to the user's status. The audio module 10 is used to broadcast data through voice when facing some elderly patients, and make direct judgments on blood pressure, such as if your blood pressure is high, and make suggestions in this form, thereby preventing the elderly from not understanding the data displayed on the screen 2. This function can be regulated by the PLC module 7 to turn on and off, and can be freely selected. When the emergency module 11 detects that the user's blood pressure is too abnormal, it will urgently notify the preset emergency contact. The PLC module 7 can be set by touch screen through the screen 2. If it is used by the elderly, it can be set in advance by the family. The PLC module 7 can be set to perform timed measurements. In order to prevent the elderly from being frightened, the audio module 10 will be used before the measurement to broadcast the time like a time report, indicating that the measurement state is about to be entered, so that the family can obtain the user's blood pressure information in time, and in order to prevent the user from having an emergency and being inconvenient to measure, the user can stop the measurement state directly by rotating the knob 12 without touching the screen through the screen 2 to restore it to its original state.
