DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] First embodiment The present invention provides Figures 1 to 6 A wearable ECG signal acquisition device shown in the figure includes a winding component 1, a tightening component 2 and an adjustment component 3. A containing box 4 is provided above the adjustment component 3. An ECG monitoring module 5 and a wire-receiving component 6 are provided inside the containing box 4 respectively. An alarm is provided on the surface of the ECG monitoring module 5. When the value of the ECG monitoring module 5 changes, an alarm can be triggered for early warning. The ECG monitoring module 5 can analyze the ECG frequency collected by the first adsorption electrode 604 and the second adsorption electrode 8 to form an intuitive ECG. A standard ECG frequency is provided inside the database of the ECG monitoring module 5. By comparing the newly detected ECG value with the standard ECG value, when the detected value deteriorates, the adjustment component 3 is used to adjust the whole to eliminate external factors and ensure the accuracy of the value. When the adjustment is completed, the value is still abnormal, and then an alarm is used to warn, so that emergency treatment can be carried out in time.

[0023] The wire taking-up assembly 6 includes a wire taking-up drum 601. The wire taking-up assembly 6 can freely extend or store the ECG wire 603. When extended, the position of the first adsorption electrode 604 can be freely adjusted, making it convenient to use as a whole. When stored, the ECG wire 603 can be wound on the surface of the wire taking-up drum 602 to avoid the ECG wire 603 from getting tangled during storage, which affects the next detection. The inner wall of the wire taking-up drum 601 is rotatably connected to the wire taking-up drum 602. The upper part of the outer surface of the wire taking-up drum 602 is provided with the ECG wire 603, and the ECG wire The other end of 603 passes through the take-up assembly 6 and the accommodating box 4 respectively. The other end of the ECG wire 603 is provided with two symmetrical first adsorption electrodes 604. A torsion spring is provided between the take-up shaft 602 and the take-up drum 601. When the ECG wire 603 extends outward, it can drive the take-up shaft 602 to rotate so that the torsion spring is stressed to generate a resetting elastic force. When the detection is completed, the ECG wire 603 is released and under the action of the torsion spring tension, the ECG wire 603 can be re-introduced into the take-up drum 601, thereby achieving the purpose of storing the ECG wire 603.

[0024] A groove is provided on the bottom surface of the adjustment component 3, and the groove can constrain the position of the clamping plate 7 so that it can rise or fall smoothly. At the same time, under the action of the groove, the movement amplitude of the clamping plate 7 is increased, so that it can adapt to different arm sizes and avoid the situation of inadequate clamping. The clamping plate 7 is slidably connected inside the groove, and the bottom surface of the clamping plate 7 is arc-shaped. The clamping plate 7 is made of rubber material. By matching the arc-shaped bottom surface, the clamping plate 7 can fit the skin better and avoid errors. Two symmetrical second adsorption electrodes 8 are provided on the bottom surface of the clamping plate 7. By providing two second adsorption electrodes 8, there are two sets of data when collecting data, which can be compared to reduce errors.

[0025] The adjustment component 3 has a cavity 9 inside, and the cavity 9 is filled with a certain amount of gas. After being compressed, air can circulate. The cavity 9 is slidably connected with a first partition 10. The first partition 10 divides the cavity 9 into two parts, an upper space and a lower space. When the gas in the upper space increases, it can drive the second partition 11 to move downward, squeeze the gas in the lower space, and make the gas gradually pass through the gas storage box 13 into the expansion tube 16, so that the expansion tube 16 expands, making the overall fixation more stable. The middle part of the upper surface of the first partition 10 is plugged with a second partition 11. 1. The cross section of the second partition 11 is in a "convex" shape. The first partition 10 and the second partition 11 are both provided with magnets 12 in the middle of one side close to each other, and the two magnets 12 are magnetically attracted to each other. Under the action of the magnetic attraction, the first partition 10 and the second partition 11 are fixed together. When the wind force borne by the first partition 10 and the second partition 11 is greater than the magnetic force between the first partition 10 and the second partition 11, the first partition 10 and the second partition 11 can be separated, so that the wind force passes through the gap between the first partition 10 and the second partition 11, so as to achieve the purpose of air intake.

[0026] Two symmetrical push rods 19 are inserted into the bottom wall of the cavity 9, and the upper end of each push rod 19 is fixedly connected to the bottom surface of the first partition 10. The push rod 19 can move with the first partition 10, thereby driving the clamping plate 7 to move downward, so that the second adsorption electrode 8 is in closer contact with the skin, avoiding errors during detection. The lower end of each push rod 19 is fixedly connected to the upper surface of the clamping plate 7, and the outer surface of each push rod 19 is sleeved with a spring. When the first partition 10 descends, the spring can be compressed to generate a reset elastic force. When the first partition 10 and the second partition 11 are separated, the gas is discharged from the gap between the first partition 10 and the second partition 11 to reduce the air pressure on the first partition 10. Under the action of the spring, the clamping plate 7 can be driven to move upward, so that a certain gap appears between the clamping plate 7 and the arm, and the sweat is quickly removed by wind force. The upper end of the spring is fixedly connected to the bottom surface of the first partition 10, and the lower end of the spring is fixedly connected to the bottom wall of the cavity 9.

[0027] A fan 20 is provided in the middle of the bottom wall of the cavity 9, and the upper end of the fan 20 passes through the upper surface of the second partition 11. When the fan 20 is started, it can introduce the outside wind into the upper space, and the gas inside the upper space gradually increases. Under the pressure of the air pressure, the first partition 10 drives the second partition 11 to gradually move downward, squeezing the gas inside the lower space, so that the gas passes through the air inlet groove 14 and the air storage box 13 in turn and enters the expansion tube 16, so that the expansion tube 16 gradually expands. Under the action of the two push rods 19, the clamping plate 7 gradually moves downward. Through the two-way movement, the arm is completely fixed, so that the second adsorption electrode 8 is firmly attached to the skin surface to avoid affecting the detection accuracy. The outer surface of the fan 20 is sleeved with a spring. When the second partition 11 gradually moves downward, it squeezes the spring and generates a restoring elastic force. When the wind force on the second partition 11 gradually decreases, the second partition 11 is pushed up by the spring, so that the second partition 11 is re-adsorbed on the bottom surface of the first partition 10 through the magnet 12, thereby achieving the purpose of the combination of the two. In preparation for the follow-up, the upper end of the spring is fixedly connected to the upper surface of the second partition 11, and the lower end of the spring is fixedly connected to the inner bottom wall of the cavity 9. An air inlet pipe 21 is provided on the outer surface of the fan 20, and the rear end of the air inlet pipe 21 passes through the outer surface of the adjustment component 3. Under the action of the air inlet pipe 21, the outside air can be introduced into the cavity 9 through the fan 20, thereby achieving the purpose of air supply.

[0028] Air storage boxes 13 are provided on the left and right sides of the adjustment component 3, and an air intake groove 14 is opened between each air storage box 13 and the adjustment component 3. The air intake groove 14 can introduce the air inside the cavity 9 into the air storage box 13. The side walls of the two air storage boxes 13 close to each other are opened with an inclined sweat removal port 15. When the sweat removal port 15 is opened, the gas inside the air storage box 13 can be quickly discharged, and the sweat removal port 15 is inclined to change the wind direction, so that the discharged gas can flow along the trajectory of the bottom surface of the clamping plate 7, so that the sweat can be dried and the surrounding temperature can be reduced to prevent the generation of new sweat. The other end of each sweat removal port 15 passes through the adjustment component 3.

[0029] The bottom surface of the air storage box 13 on the right side is connected with a "C"-shaped expansion tube 16. The expansion tube 16 can gradually expand with the gas inside the expansion tube 16, causing compression on the lower part of the arm to make it more firmly fixed. A temperature sensor is provided on the surface of the expansion tube 16, which can detect the temperature at this time in real time and transmit the data to the ECG monitoring module 5 through wireless. The ECG value detected by the ECG monitoring module 5 is corrected according to the temperature at this time to avoid affecting the detection accuracy due to the increase in temperature. The front end of the expansion tube 16 is connected with a one-way pressure valve, which is When the air pressure reaches the threshold value, the one-way pressure valve can be opened to allow the gas to quickly enter the exhaust pipe 17 and be discharged from the exhaust nozzle 18, so that the gas inside the expansion tube 16 can circulate, so that the heat can be taken away by heat exchange, thereby achieving the purpose of heat dissipation and reducing the production of sweat. The other end of the one-way pressure valve is connected to the exhaust pipe 17, and the lower end of the exhaust pipe 17 is provided with an exhaust nozzle 18. The cross-section of the exhaust nozzle 18 is an isosceles trapezoidal shape, which can compress the exhausted gas and increase the spray distance, thereby being able to dissipate heat and cool down most areas of the lower arm.

[0030] The tightening component 2 is arranged below the right air storage box 13, and the tightening component 2 includes a first wristband 201. The outer surface of the first wristband 201 is fixedly connected to the outer surface of the expansion tube 16, and the first wristband 201 can fix the position of the expansion tube 16. The left end of the first wristband 201 is provided with a buckle 202. The winding component 1 is arranged below the left air storage box 13, and the winding component 1 includes a second wristband 101. The outer surface of the second wristband 101 is provided with a plurality of equidistantly arranged through grooves 102, and the through grooves 102 and the buckle 202 are adapted to each other. The first wristband 201 and the second wristband 101 are wound and connected. Through the mutual cooperation of the buckle 202 and the through groove 102, the first wristband 201 and the second wristband 101 can be fixed together to achieve the purpose of splicing, and can also be disassembled to make it more convenient to wear.

[0031] In actual use, first remove the buckle 202 from the through slot 102 to disengage the first wristband 201 and the second wristband 101, pass the arm through the space formed by the first wristband 201 and the second wristband 101, fix it again with the buckle 202, pull the ECG wire 603 out of the take-up reel 601 to a suitable size, and fix the first adsorption electrode 604 at the chest position.

[0032] When the value detected by the ECG monitoring module 5 is lower than the threshold, the following adjustments need to be made: Start the fan 20. Under the action of the fan 20, the outside air is introduced into the upper space through the air inlet pipe 21, so that the gas inside the upper space gradually increases. Under the action of air pressure, the first partition 10 is pushed to drive the second partition 11 to move downward gradually, firstly reducing the volume of the lower space, so that the internal air pressure of the lower space gradually increases, and enters the two air storage boxes 13 through the air inlet groove 14. As the internal gas of the right air storage box 13 gradually increases, part of the gas enters the expansion tube 16, causing the expansion tube 16 to gradually expand. At the same time, when the first partition 10 gradually moves downward, the two push rods 19 can drive the clamping plate 7 to move downward. Through the downward and upward forces, the whole is more stable when fixed on the arm. At the same time, the two second adsorption electrodes 8 are in closer contact with the skin to avoid errors during detection. When the adjustment is completed, the fan 20 stops running.

[0033] After the corresponding adjustment, if the value detected by the ECG monitoring module 5 is still lower than the threshold, it indicates that the value is abnormal at this moment, and then an alarm is used to warn, so that emergency treatment can be carried out in time.

[0034] When the ECG monitoring module 5 continuously monitors a sudden drop in the value, the following adjustments need to be made: first, the temperature sensor is used to detect the body temperature at this time, and the ECG value at this time is corrected according to the temperature at this time. After the correction is completed, if the ECG value is still abnormal, the fan 20 is started again, and the external wind force is re-introduced into the upper space through the air inlet pipe 21, so that the gas entering the upper space gradually increases, and under the action of air pressure, the first partition 10 and the second partition 11 move downward again, so that the spring is compressed to generate a reset elastic force. At the same time, since two springs are arranged under the first partition 10, which is greater than the number of springs under the second partition 11, when the pressure caused by the air pressure is greater than the suction force between the magnets 12, the second partition 11 will be moved downward. The first partition 10 is detached from the bottom surface, so that a gap appears between the first partition 10 and the second partition 11, so that the gas can quickly pass through the gap into the lower space. Since the gas in the upper space passes through the gap into the lower space, the pressure on the first partition 10 is reduced. Under the action of the spring, the first partition 10 can be pushed up, so that the push rod 19 drives the clamping plate 7 to rise, so that a gap appears between the second adsorption electrode 8 and the skin. Since the clamping plate 7 rises, the sweat removal port 15 can be opened, so that the gas inside the air storage box 13 can be quickly discharged, and the sweat removal port 15 is inclined to change the wind direction, so that the discharged gas can circulate along the trajectory of the bottom surface of the clamping plate 7, so that the sweat can be dried, and at the same time the surrounding temperature can be reduced to prevent the production of new sweat.

[0035] As the gas in the lower space gradually increases, under the action of air pressure, part of the gas enters the air storage box 13 through the air inlet groove 14 to fill the gas inside the air storage box 13. Since the exhaust volume of the sweat removal port 15 is lower than the intake volume of the fan 20, when the air storage box 13 on the right side is relatively full, the gas can be filled into the expansion tube 16 again to make it expand again, and the arm is lifted up again, and the clamping plate 7 is raised to cause the gap between the second adsorption electrode 8 and the skin to fit again, so as to avoid affecting the subsequent detection accuracy. At the same time, the gas entering the expansion tube 16 gradually increases, and when the internal air pressure reaches the threshold of the one-way pressure valve, it can be opened to allow the gas to enter the exhaust pipe 17 through the one-way pressure valve, and the gas is discharged through the exhaust nozzle 18, so that the vast area of ​​the lower arm can be dissipated and cooled. At the same time, since the air in the expansion tube 16 is always circulating, the heat can be taken away by heat exchange, thereby achieving the purpose of heat dissipation and reducing the production of sweat.

[0036] The main functions realized by the present invention are: the ECG frequency collected by the first adsorption electrode 604 and the second adsorption electrode 8 can be analyzed through the ECG monitoring module 5 to form an intuitive ECG, and the ECG monitoring module 5 database is provided with a standard ECG frequency. By comparing the newly detected ECG value with the standard ECG value, when the detected value is low, the fan 20, the first partition plate 10 and the push rod 19 cooperate with each other to make the clamping plate 7 drop, so that the second adsorption electrode 8 is firmly attached to the skin surface to avoid errors during detection, and the fan 20 and the air storage box 13 cooperate with each other to make the expansion tube 16 expand to support the arm, so that the overall fixation is more firm to avoid errors during exercise. Shaking affects the detection accuracy. When the detection value drops suddenly, the first partition 10 and the second partition 11 can be separated through the cooperation of the fan 20 and the magnet 12. Under the action of the spring elasticity, the first partition 10 drives the clamping plate 7 to rise, and the sweat removal port 15 is opened, so that the sweat can be blown dry and the surrounding temperature is reduced to prevent new sweat from being produced. Through the cooperation of the one-way pressure valve and the fan 20, the gas inside the expansion tube 16 can circulate quickly, and the heat under the arm can be reduced by heat exchange to avoid new sweat from affecting the detection accuracy. When the adjustment is completed, the value is still abnormal, and then an alarm is used to warn, so that emergency treatment can be carried out in time.
