Description

Technical Field

[0001] The utility model belongs to the technical field of human health monitoring, and specifically relates to a health smart watch with a blood pressure monitoring function. Background Art

[0002] Blood pressure is a direct indicator of a person's health. It's caused by the heart's contraction and relaxation, which pump blood throughout the body. The pressure exerted on the vessel walls by blood pressure as it flows through blood vessels throughout the body is crucial for the prevention and diagnosis of cardiovascular disease. Traditional sphygmomanometers have evolved from the original mercury-based stethoscope to cuff-based electronic sphygmomanometers. With the advancement of electronics, communications, and computer technologies, products with blood pressure functions have become increasingly miniaturized, and an increasing number of portable devices are integrating blood pressure monitoring capabilities. In recent years, research has focused both domestically and internationally on wearable blood pressure monitoring systems. Smart health watches primarily utilize oscillometric air pump monitoring technology and photoelectric monitoring technology based on photoplethysmography (PPG) signals.

[0003] The above-mentioned existing photoelectric blood pressure monitoring technology has the following defects: when the watch back cover module is damaged, bumped or blurred during use, it is difficult for the user to maintain and replace the watch back cover module by themselves, which will greatly reduce the sampling signal-to-noise ratio of the PPG photoelectric signal, thereby reducing the accuracy and effectiveness of blood pressure monitoring; if the user replaces it by himself or goes to a professional repair agency to be replaced by professionals, the watch back cover module is often unsuitable or non-original craftsmanship, resulting in the internal dust and waterproof structure of the watch being destroyed, thereby reducing the user experience and the safety and stability of the watch. Utility Model Content

[0004] The utility model provides a health smart watch with a blood pressure monitoring function, which solves the technical problems of existing photoelectric smart blood pressure monitoring watches, such as the back cover is easily worn, which reduces the sampling signal-to-noise ratio of the PPG photoelectric signal, and is difficult to replace and repair.

[0005] The utility model can be realized through the following technical solutions:

[0006] A health smart watch with a blood pressure monitoring function includes a dial body, wherein both ends of the dial body are respectively connected to corresponding watch straps; a detachable anti-wear cover is provided on the bottom surface of the dial body that contacts the skin; an opening is provided at a position of the anti-wear cover corresponding to the detection port on the bottom surface, and a light-transmitting film is encapsulated on the opening.

[0007] Furthermore, a boss is provided at the central position of the bottom surface of the dial body, a plurality of detection ports are provided on the top surface of the boss at even intervals around the center, and an opening is provided on the anti-wear cover at a position corresponding to each detection port, each of which is encapsulated with a light-transmitting film;

[0008] A charging electrode is provided at the front end of the bottom surface of the dial body, and a positioning column is provided at the rear end of the bottom surface. The positioning column cooperates with the positioning through hole on the anti-wear cover body, and the charging electrode cooperates with the electrode through hole on the anti-wear cover body, and the opening area of the electrode through hole is larger than that of the charging electrode.

[0009] Furthermore, the shape of the anti-wear cover matches the shape of the bottom surface of the dial body, and the two are assembled magnetically.

[0010] Furthermore, annular magnets are symmetrically arranged on the edge of the top surface of the boss of the dial body, and annular magnets are also arranged at corresponding positions of the anti-wear cover.

[0011] Furthermore, a power switch button, ECG and BIA detection buttons, and an SOS button are sequentially arranged on one side of the dial body, and ECG and BIA detection buttons are also arranged at positions corresponding to the ECG and BIA detection buttons on the other side.

[0012] Furthermore, the detection port is connected to a photoelectric sensor, and the photoelectric sensor is used to detect the blood pressure information of the user.

[0013] The beneficial technical effects of the utility model are as follows:

[0014] 1. By using the arc-shaped magnet on the bottom surface of the dial body and the arc-shaped magnet on the inner wall of the anti-wear cover to jointly construct a magnetic detachable structure, the dial body and the anti-wear cover can be fixed, replacing the traditional screw fixing method. It is easy to operate and highly practical, thereby solving the problem that the smart health watch with blood pressure monitoring function cannot quickly and easily replace the watch back cover. At the same time, since the waterproof structure of the dial body of the utility model is separated from the anti-wear cover, replacing the anti-wear cover will not destroy the waterproof and dustproof function of the watch itself, and can well ensure the collection quality of the PPG signal.

[0015] 2. The electrode through-holes and positioning through-holes on the anti-wear cover cooperate with the charging electrodes and positioning posts on the dial body respectively, which can play a good positioning role and avoid misalignment of the anti-wear cover. At the same time, the user can separate the anti-wear cover from the dial body by pressing the charging electrode and the positioning post, which is easy to disassemble.

[0016] 3. Through the cooperation structure of the photoelectric sensor on the boss of the dial body and the wear-resistant cover body, the watch body can fit more closely on the human arm. When the PPG signal acquisition module inside the photoelectric sensor collects signals, the light signal passes through the light-transmitting film of the wear-resistant cover body and irradiates on the user's skin, reducing the leakage of the light signal. At the same time, the wear-resistant cover body that is convenient for disassembly and maintenance can be replaced in time according to the usage situation, further improving the signal-to-noise ratio of the collected signals. Finally, the signals will be transmitted back to the health smart watch, and the blood pressure of the user will be calculated through the pre-debugged PPG-based blood pressure algorithm inside, so as to achieve the purpose of calculating the blood pressure of the health smart watch with the blood pressure monitoring function more accurately.

[0017] 4. The present utility model uses a detachable wear-resistant cover body to replace the direct improvement of the bottom surface of the dial body to solve the technical problem that the wear of the rear cover affects the PPG signal. It has a low cost, is conducive to large-scale promotion, and at the same time is easier to meet the different needs of different people for the rear cover. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will describe in detail the specific embodiments of the present utility model in conjunction with the accompanying drawings and preferred embodiments.

[0025] Such as Figures 1-5As shown in the figure, the present utility model provides a health smart watch with blood pressure monitoring function, including a watch dial body 1. Both ends of the watch dial body 1 are respectively connected to their corresponding watch straps 2. A detachable anti-abrasion cover body 3 is provided on the bottom surface of the watch dial body 1 that contacts the skin. An opening 31 is provided at the position of the detection port corresponding to the bottom surface of the anti-abrasion cover body 3, and a light-transmitting film is encapsulated on the opening 31. In this way, by adding an anti-abrasion cover body 3 instead of directly improving the bottom surface of the watch dial body 1, the problem that the smart health watch with blood pressure monitoring function cannot quickly and simply replace the watch back cover can be well solved. At the same time, since the waterproof structure of the watch dial body itself is separated from the anti-abrasion cover body, replacing the anti-abrasion cover body will not damage the waterproof and dustproof functions of the watch itself. Moreover, the timely replaced anti-abrasion cover body can well guarantee the acquisition quality of the PPG signal, which helps to improve the monitoring accuracy of the health smart watch with blood pressure monitoring function, such as blood pressure monitoring, etc.

[0026] Specifically as follows:

[0027] On one side of the watch dial body 1, a power switch button 11, an ECG and BIA detection button 12, and an SOS button 13 are sequentially arranged. At the position corresponding to the ECG and BIA detection button 13 on the other side, an ECG and BIA detection button 13 is also arranged. When performing ECG and BIA detections, the ECG and BIA detection buttons 13 on both sides of the watch dial body need to be pressed simultaneously. A touch screen 14 is provided on the top surface of the watch dial body 1, which is used to display data, curves, etc. corresponding to various detection results.

[0028] The outer shape of the anti-abrasion cover body 3 matches the bottom surface outer shape of the watch dial body 1. The two are assembled by magnetic attraction to achieve the detachable function, replacing the traditional screw fixation method, which is convenient to operate and has strong practicability.

[0029] A boss 15 is provided at the central position of the bottom surface of the watch dial body 1. A plurality of detection ports 16 are evenly spaced around the center of the top surface of the boss 15. Openings 31 are provided at the positions corresponding to each detection port 16 on the wear-resistant cover body 3, and light-transmitting films are encapsulated thereon. A charging electrode 17 is provided at the front end of the bottom surface of the watch dial body 1, and a positioning post 18 is provided at the rear end of its bottom surface. The positioning post 18 cooperates with the positioning through hole 32 on the wear-resistant cover body 3, and the charging electrode 17 cooperates with the electrode through hole 33 on the wear-resistant cover body 3, and the opening of the electrode through hole 33 is larger than the charging electrode 17. These detection ports are connected to a photoelectric sensor, which is used to detect the blood pressure information of the user. Since it is not easy to accurately assemble the wear-resistant rear cover onto the watch dial body at one time only by the cooperation of the positioning post and the positioning through hole, the present invention also provides the cooperation of the charging electrode and the electrode through hole, so that the wear-resistant rear cover can be quickly and accurately assembled onto the watch dial body, playing an anti-fooling role. In addition, the bottom surface of the watch dial body adopts a boss structure, and the detection ports are arranged on the boss, so that the watch body can fit more closely on the human arm. When the PPG signal acquisition module inside the photoelectric sensing module performs signal acquisition, the boss structure can make the light-transmitting film of the wear-resistant cover body fit more closely with the user's skin, reducing the leakage of optical signals.

[0030] A ring magnet 19 is provided at the edge of the top surface of the boss of the watch dial body 1, and a ring magnet 19 is also provided at the corresponding position of the wear-resistant cover body 3. Of course, two semi-circular arc magnets can also be used.

[0031] During installation, first, the user determines that the arc magnet of the watch dial body has magnetism. The user picks up the watch body with one hand and picks up the wear-resistant cover body with the other hand, aligns the arc magnet in the wear-resistant cover body with the arc magnet of the watch dial body, and at the same time ensures that the positioning through hole on the wear-resistant cover body aligns with the positioning post on the watch dial body and the electrode through hole aligns with the charging electrode. At this time, the user can feel an obvious magnetic force. Then the user releases the wear-resistant cover body. Through the magnetic force between the arc magnet in the watch dial body and the arc magnet in the wear-resistant cover body, the wear-resistant cover body can be automatically installed at the bottom of the watch dial body.

[0032] When in use, after the user straps the watch band on the wrist, the photoelectric sensor in the watch dial body collects the PPG signal of the user's wrist through the light-transmitting film of the wear-resistant cover body. The returned high-quality and high-signal-to-noise ratio PPG signal is calculated through the blood pressure algorithm in the watch, and the obtained blood pressure result will be displayed through the touch screen, and then the result can be transmitted to the data background through the wireless transmission module installed inside the watch.

[0033] When disassembling, first, the user picks up and fixes the dial body with one hand, presses the positioning post of the dial body with the thumb of the other hand, and at the same time uses the index finger to push the charging electrode through the electrode through-hole on the abrasion-proof cover body, so that the instantaneous thrust cancels out the magnetic force, and the abrasion-proof cover body is pushed away from the dial body, thereby separating the dial body from the abrasion-proof cover body from each other.

[0034] Although the specific implementation manners of the present utility model have been described above, those skilled in the art should understand that these are only examples. Without departing from the principle and essence of the present utility model, various changes or modifications can be made to these implementation manners. Therefore, the protection scope of the present utility model is defined by the appended claims.
