Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a smart bracelet capable of dynamically monitoring atrial fibrillation. Background Art

[0002] Atrial fibrillation is the most common persistent arrhythmia in clinical practice. With the growth of the elderly population, the number of patients with atrial fibrillation continues to increase. Currently, the annual incidence of atrial fibrillation in men is about 0.78‰, and that in women is 0.6%. The two major problems in the cardiovascular field of medicine in the 21st century are atrial fibrillation and heart failure. Atrial fibrillation can not only cause heart failure, but is also an independent risk factor for stroke, with a high mortality and disability rate, which greatly reduces the quality of life of patients and increases the social burden.

[0003] Early detection and diagnosis of atrial fibrillation are particularly important. At present, our diagnosis of atrial fibrillation mainly relies on electrocardiogram, including 12-lead electrocardiogram and 24-hour dynamic electrocardiogram, in addition to relatively less specific methods such as physical examination and cardiac auscultation. However, since some patients present with asymptomatic or paroxysmal atrial fibrillation, clinical diagnosis is more difficult and easy to miss, including patients after atrial fibrillation surgery, the above problems also exist. Therefore, it is necessary to seek more long-term and accurate diagnostic methods for such patients.

[0004] Wearable devices are an emerging era product of technological development in recent years. They have changed the previous disease monitoring methods and treatment concepts and are widely used in the fields of motion analysis, sleep monitoring and quality assessment.

[0018] In summary, the present invention mainly has the following beneficial effects:

[0019] 1. The present invention sets a bracelet component and a monitoring component. First, the bracelet body is worn on the wrist through a strap. Under normal circumstances, the bracelet body can provide the wearer with basic information such as time that a smart bracelet can provide. During the wearing process, the monitoring component will dynamically monitor the wearer's atrial fibrillation. Specifically, the LED light source (usually green light or red light) installed inside the bracelet body will periodically emit light to the wrist skin. When the light penetrates the skin and encounters blood, the hemoglobin in the blood will absorb part of the light, while the unabsorbed light will be reflected back. The flow of blood causes the blood to absorb and reflect light periodically, and the photodiode inside the bracelet body is responsible for receiving the reflected light. The returned optical signal is converted into an electrical signal. The strength changes of these electrical signals are closely related to the rhythm of the heartbeat. Further, the chip inside the bracelet body processes the received electrical signals, including filtering, amplification and other steps to remove noise and enhance the signal, and then analyzes the periodic changes of the signal through a specific algorithm to calculate the heart rate value. The display screen of the bracelet body will display the calculated heart rate value for the user to view in real time, and the control system inside the bracelet body will record the wearer's heart rate value. When the heart rate is detected to be irregular and too fast, the bracelet body will alert the wearer, and the wearer can seek medical attention in time, thereby protecting the wearer's life and health.

[0020] 2. The present invention provides a wiping component, a fragrance component and a liquid storage tank component. The control system inside the bracelet body drives the wiping component to operate before each operation of the monitoring component, thereby enabling the wiping component to clean the monitoring component and the skin on the wearer's wrist to ensure the accuracy of the monitoring values. Specifically, the electric guide rail drives the slider to move on its outer wall, and the movement of the slider drives the wiping cotton to move synchronously through the synchronization rod. The movement of the wiping cotton will wipe off foreign matter on the emission port of the LED light source and the skin on the wrist, thereby not affecting the angle and intensity of the light source emission, thereby ensuring the accuracy of atrial fibrillation monitoring. When the slider moves, its extension part will move synchronously. The movement of the extension part will squeeze the driven plate when it moves to contact with the driven plate, so that the driven plate will push the driving rod to move, and the driving rod will then push the piston plate to move and squeeze The reset spring and the movement of the piston plate will squeeze the fragrance liquid to spray out from the atomizing nozzle, thereby eliminating the odor on the wearer's wrist and providing a moisturizing effect for the wrist skin in the dry season, which significantly improves the wearer's comfort. When the extension part is reset and moved, the reset spring will drive the piston plate to move outward and reset. At this time, the water inlet pipe will absorb the fragrance liquid from the liquid storage tank under the action of the negative pressure inside the cavity, thereby achieving the effect of automatic liquid replenishment. Furthermore, the movement of the extension part will also drive the driving tooth plate to move. When the driving tooth plate moves to contact with the driven gear, it will drive the driven gear to rotate. After the driven gear rotates, it will drive the stirring shaft to rotate. After the stirring shaft rotates, it will drive the stirring blades to rotate. The rotation of the stirring blades will stir the fragrance liquid in the liquid storage tank, thereby achieving uniform treatment of the fragrance liquid and ensuring the quality of the sprayed fragrance liquid.

[0040] The working principle of the present invention is as follows: first, the wristband body 101 is worn on the wrist through the strap 105. In general, the wristband body 101 can provide the wearer with basic information such as time that a smart wristband can provide;

[0041] During the wearing process, the monitoring component 2 will dynamically monitor the wearer's atrial fibrillation. Specifically, the LED light source 201 (usually green light or red light) installed inside the wristband body 101 will periodically emit light to the wrist skin. When the light penetrates the skin and encounters the blood, the hemoglobin in the blood will absorb part of the light, and the unabsorbed light will be reflected back. The flow of blood causes the absorption and reflection of light by the blood to change periodically, and the photodiode 202 inside the wristband body 101 is responsible for receiving the reflected light signal and converting it into an electrical signal. The strength changes of these electrical signals are closely related to the rhythm of the heartbeat.

[0042] Furthermore, the chip inside the wristband body 101 processes the received electrical signal, including filtering, amplification and other steps, to remove noise and enhance the signal, and then analyzes the periodic changes of the signal through a specific algorithm to calculate the heart rate value. The display screen 102 of the wristband body 101 will display the calculated heart rate value for the user to view in real time, and the control system inside the wristband body 101 will record the heart rate value of the wearer. When the heart rate is detected to be irregular and too fast, the wristband body 101 will warn the wearer, and the wearer can seek medical examination in time, thereby protecting the life and health of the wearer;

[0043] In addition, the control system inside the wristband body 101 will drive the wiping component 3 to operate before each operation of the monitoring component 2, so that the wiping component 3 can clean the monitoring component 2 and the skin on the wearer's wrist to ensure the accuracy of the monitoring value;

[0044] Specifically, the electric guide rail 303 drives the slider 304 to move on its outer wall, and the movement of the slider 304 drives the wiping cotton 301 to move synchronously through the synchronization rod 305. The movement of the wiping cotton 301 will wipe off the emission port of the LED light source 201 and foreign matter on the skin at the wrist, thereby not affecting the angle and intensity of the light source emission, thereby ensuring the accuracy of atrial fibrillation monitoring;

[0045] When the slider 304 moves, its extension part 306 will move synchronously. When the extension part 306 moves to contact with the driven plate 405, the driven plate 405 will be pressed to move. Therefore, the driven plate 405 will push the driving rod 404 to move. The driving rod 404 will push the piston plate 403 to move and squeeze the return spring 409. The movement of the piston plate 403 will squeeze the fragrance liquid to be sprayed from the atomizing nozzle 407, thereby eliminating the odor on the wrist of the wearer and providing a moisturizing effect for the skin on the wrist in dry seasons, which significantly improves the comfort of the wearer.

[0046] Furthermore, when the extension portion 306 is reset, the reset spring 409 drives the piston plate 403 to move outward and reset. At this time, the water inlet pipe 408 absorbs the fragrance liquid from the liquid storage tank 501 under the negative pressure inside the cavity 402, thereby achieving the effect of automatic liquid replenishment.

[0047] It is worth noting that in the present embodiment, the movement of the extension portion 306 will also drive the driving tooth plate 307 to move. When the driving tooth plate 307 moves to contact the driven gear 502, it will drive the driven gear 502 to rotate. After the driven gear 502 rotates, it will drive the stirring shaft 504 to rotate. After the stirring shaft 504 rotates, it will drive the stirring blade 505 to rotate. The rotation of the stirring blade 505 will stir the fragrance liquid in the liquid storage tank 501, thereby achieving uniform treatment of the fragrance liquid and ensuring the quality of the sprayed fragrance liquid.

[0048] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
