Description
Technical Field
[0001] The present invention relates to the technical field of health monitoring, and in particular to a wearable intelligent monitoring device for the elderly. Background Art
[0002] As the age increases, the body functions of the elderly gradually decline, and the risk of various chronic diseases increases. Among them, heart rate, blood oxygen and electrophysiological signals are important indicators reflecting physical conditions. Wearable smart monitoring devices can provide continuous health monitoring for the elderly, and can know whether the heart rate, blood oxygen and electrophysiological signals are normal at any time, so as to timely discover potential health problems. There is an existing smart bracelet that integrates the heart rate, blood oxygen and electrophysiological signal monitoring functions. It is worn on the wrist through a rubber strap. However, since the smart monitoring device needs to be worn for a long time, and the sensors on the back of the smart bracelet for monitoring the heart rate, blood oxygen and electrophysiological signals need to be in contact with the skin when monitoring related items, the smart bracelet needs to be worn tightly when worn, which results in a large binding force of the bracelet on the wrist of the elderly. At the same time, since the strap is in contact with the wrist skin for a long time, the smart bracelet is warmed and sweats at the wearing part, resulting in poor wearing comfort of the smart bracelet. For the comfort of wearing, the existing elderly usually wear the smart bracelet loosely, which also results in the sensor on the back of the smart bracelet only being able to contact the wrist skin but not being able to fit completely, resulting in low monitoring accuracy. Summary of the invention

DETAILED DESCRIPTION
[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
[0018] A wearable intelligent monitoring device for the elderly, please refer to Figure 1-Figure 6 , including: a shell 1, the shell 1 is provided with a protrusion 103 and a mounting hole 104, a magnet sheet 2 is fixedly connected in the mounting hole 104; a power piece 3 is arranged in the mounting hole 104 and contacts with the magnet sheet 2, the power piece 3 is sealingly and slidably connected with the mounting shell 4, and a spring is fixedly connected between the power piece 3 and the mounting shell 4; a skin electrode 5 is installed in the mounting shell 4, and an optical sensor 6 is installed in the mounting shell 4; a connecting tube 7 is fixedly connected to the mounting shell 4 and is limitedly and sealingly slidably connected with the power piece 3; a coil 8 is fixedly connected in the power piece 3, the part of the power piece 3 located on the inner side of the coil 8 is made of ferromagnetic material, the skin electrode 5, the optical sensor 6 and the coil 8 are connected in series through a wire, the connecting tube 7 is provided with a through hole for the wire to pass through, and the coil 8 is used to generate a magnetic field that magnetically repels the magnet sheet 2 after power is turned on; the side of the mounting shell 4 away from the magnet sheet 2 is coplanar with the side of the protrusion 103 away from the magnet sheet 2.
[0019] The above scheme aims to solve the problem that the existing smart bracelets are usually worn loosely, which causes the sensor on the back of the smart bracelet to be unable to fully fit the skin, resulting in low monitoring accuracy of the smart bracelet; when the skin electrode 5 and the optical sensor 6 are started, the device uses the coil 8 and the power part 3 to form an electromagnet, and generates a magnetic field that repel the magnet sheet 2, and uses the magnetic force to push the skin electrode 5 and the optical sensor 6 to move and fit the skin, thereby reducing the probability that the skin electrode 5 and the optical sensor 6 cannot fit the skin when worn loosely, and improving the monitoring accuracy; the shell 1 is fixedly connected to the main strap 101 and the auxiliary strap 102, the main strap 101 and the auxiliary strap 102 can be made of nylon, which has pores and elasticity, and can allow air to circulate in the pores of the main strap 101 and the auxiliary strap 102, thereby improving the air permeability of the main strap 101 and the auxiliary strap 102, and further improving the wearing comfort; the lower side of the mounting shell 4 is coplanar with the lower side of the raised portion 103, on the one hand, it is convenient for the mounting shell 4 to contact with the wrist skin, on the other hand, the mounting hole 104 is "filled" by the mounting shell 4, thereby reducing the discomfort felt by the elderly while wearing the device. While the elderly wear the device, at least the main strap 101, the auxiliary strap 102 and the raised portion 103 are in contact with the wrist skin.
[0020] The shell 1 intermittently supplies power to the skin electrodes 5, the optical sensor 6 and the coil 8. The portion of the power part 3 located inside the coil 8 can be made of iron. Initially, the power part 3 is attracted by the magnet sheet 2, so that the upper side of the power part 3 fits with the magnet sheet 2. The shell 1 can establish a connection with a mobile phone via Bluetooth or a wireless network (the device uses a wireless network to transmit data), and upload the monitoring situation to the mobile phone in real time, so that the elderly or their children can view the data. An acceleration sensor can be installed in the shell 1 to monitor the movement status of the elderly, and when the elderly are detected to fall, the information will be transmitted to the mobile phones of the elderly's children via a wireless network.
[0021] The working principle of the above scheme is as follows: when the elderly use the device to monitor their physical condition, they place the shell 1 on the wrist to be worn, and connect the main strap 101 and the auxiliary strap 102. At this time, the device is worn. Then the shell 1 intermittently supplies power to the skin electrode 5, the optical sensor 6 and the coil 8. When power is supplied, the coil 8 and the power part 3 form an electromagnet together, and generate a magnetic force that repels the magnet sheet 2. At this time, the power part 3 moves downward under the action of the magnetic repulsion force, and the power part 3 drives the mounting shell 4, the skin electrode 5 and the optical sensor 6 to move downward through the adjacent spring. The mounting shell 4, the skin electrode 5 and the optical sensor 6 squeeze the skin to deform until the lower side of the mounting shell 4, the skin electrode 5 and the optical sensor 6 are completely in contact with the skin. At this time, the mounting shell 4, the skin electrode 5 and the optical sensor 6 are completely in contact with the skin. The shell 4, skin electrode 5 and optical sensor 6 stop moving, and the power part 3 continues to move downward under the action of magnetic repulsion and compresses the spring adjacent to the mounting shell 4 until the lower side of the power part 3 contacts the skin, and the power part 3 stops. At this time, the skin electrode 5 and the optical sensor 6 start and collect heart rate, blood oxygen and electrophysiological signal data, and transmit the collected data to the shell 1. The shell 1 transmits the data to the mobile phone through the wireless network, and a single detection is completed. Then the shell 1 stops supplying power to the skin electrode 5, optical sensor 6 and coil 8, and the electromagnetic magnetic field formed by the coil 8 and the power part 3 disappears. The power part 3 moves upward under the action of the magnetic attraction of the magnet sheet 2, and the above steps are repeated in reverse, so that the power part 3 drives the mounting shell 4, skin electrode 5 and optical sensor 6 to move upward and reset.
[0022] Please refer to Figure 2-Figure 5 , and also includes: an extrusion ring 9, which is fixed in the mounting hole 104 and fixed to the side of the power part 3 away from the magnet sheet 2, and the inner diameter of the mounting hole 104 is larger than the outer diameter of the power part 3; a convex particle 10 is fixed to the side of the extrusion ring 9 away from the magnet sheet 2, which is used to increase the friction between the extrusion ring 9 and the skin.
[0023] In the above scheme, it is intended to solve the problem that when the physical condition of the elderly is monitored by using smart bracelets, the elderly have wrinkles at the position where they wear the smart bracelets due to their loose skin, and the sensors on the smart bracelets cannot fully fit with the skin surface, resulting in low monitoring accuracy. In this scheme, the deformation of the extrusion ring 9 is used to squeeze the surrounding skin outward, flatten the skin near the skin electrode 5 and the optical sensor 6, improve the closeness of the skin electrode 5 and the optical sensor 6 to the skin, and then improve the monitoring accuracy of the skin electrode 5 and the optical sensor 6. Initially, the lower side of the power part 3 is located above the middle of the raised portion 103, and the generatrix length of the extrusion ring 9 is greater than the minimum distance between the lower edge of the power part 3 and the lower edge of the mounting hole 104, that is, the extrusion ring 9 is not flat at the beginning, but in a convex state. The extrusion ring 9 can be made of elastic silicone material, which provides a large friction between the extrusion ring 9 and the skin, and the lower side of the outer periphery of the extrusion ring 9 is coplanar with the lower side of the raised portion 103.
[0024] The working principle of the above scheme is as follows: when the device is used to monitor the physical condition of the elderly, when the power part 3 starts to move downward under the action of the magnetic repulsion force, the power part 3 simultaneously drives the inner side of the mounting shell 4 and the extrusion ring 9 to move downward, so that the mounting shell 4, the skin electrode 5 and the optical sensor 6 fit the skin, and the extrusion ring 9 is deformed (the extrusion ring 9 drives the convex particles 10 to move during the deformation), and the lower convex position of the extrusion ring 9 contacts the skin. As the power part 3 continues to squeeze the extrusion ring 9 to deform, the diameter of the circle surrounded by the lower convex position of the extrusion ring 9 gradually increases, and the skin at the wrist is squeezed to the surroundings, so that the skin in contact with the skin electrode 5 and the optical sensor 6 is stretched and fully contacted with the skin electrode 5 and the optical sensor 6, thereby improving the monitoring accuracy of the skin electrode 5 and the optical sensor 6; after a single detection is completed, the above steps are repeated to reset the power part 3, the mounting shell 4 and the extrusion ring 9.
[0025] Please refer to Figure 6-Figure 8 , and also includes: a sealing ring 11, which is fixed to the side of the mounting shell 4 away from the magnet sheet 2, and the lowest point of the sealing ring 11 is located below the mounting shell 4; the shell 1, the magnet sheet 2, the power part 3 and the extrusion ring 9 together form a suction chamber 111, and the suction chamber 111 is located in the mounting hole 104. A connecting flow channel 112 is provided in the mounting shell 4, and the connecting flow channel 112 is located on the inner side of the sealing ring 11, and the connecting flow channel 112 is connected to the suction chamber 111 through the through hole on the connecting tube 7.
[0026] In the above scheme, it is intended to solve the problem that when using a smart bracelet to monitor the physical condition, the sensor on it moves relative to the skin due to the shaking of the smart bracelet during the detection process, resulting in low monitoring accuracy; in this scheme, a sealing ring 11 is used to fit the skin, so that the mounting shell 4, the skin electrode 5 and the optical sensor 6 are fixed to the skin at the wrist, and when the shell 1 shakes, the shell 1 and the sensor (the sensor here refers to the skin electrode 5 and the optical sensor 6) are relatively moved, reducing the probability of the skin electrode 5 and the optical sensor 6 moving relative to the wrist skin, thereby improving the monitoring accuracy; the sealing ring 11 is made of elastic silicone material, and the lower side of the sealing ring 11 protrudes from the mounting shell 4 to ensure that the lower side of the sealing ring 11 can completely fit the skin at the wrist and form a sealed state; the sum of the elastic force of the adjacent spring of the power member 3, the force required for the deformation of the extrusion ring 9, and the force required for the deformation of the sealing ring 11 is always smaller than the magnetic repulsion between the electromagnet formed by the coil 8 and the power member 3 and the magnet sheet 2.
[0027] Please refer to Figure 6-Figure 8 , further comprising: a support ring 12, which is fixed to a side of the mounting shell 4 close to the sealing ring 11 and contacts the inner side of the sealing ring 11.
[0028] In the above scheme, the purpose is that when the skin electrode 5 and the optical sensor 6 are not activated, when the shell 1 drives the mounting shell 4 to move relative to the wrist, the support ring 12 supports the inner side of the sealing ring 11, thereby reducing the probability that the sealing ring 11 is deformed by the skin due to the friction between it and the skin; the support ring 12 is made of a hard material, and the lower side of the support ring 12 is coplanar with the lower side of the mounting shell 4.
[0029] The working principle of the above scheme is as follows: when the power piece 3 moves downward due to the magnetic repulsion force of the magnet sheet 2, the power piece 3 drives the mounting shell 4 to move downward through the adjacent spring, and the mounting shell 4 drives the sealing ring 11 to fully fit the wrist skin, so that the sealing ring 11, the mounting shell 4 and the wrist skin form a sealed chamber. As the mounting shell 4 continues to move downward, the mounting shell 4 squeezes the sealing ring 11 to deform, and the lower side of the sealing ring 11 enters the mounting shell 4 but still keeps fit with the wrist skin under the action of its own elasticity. Finally, the mounting shell 4, the skin electrode 5 and the optical sensor 6 are completely in fit with the wrist skin. As the power piece 3 continues to move downward, the volume in the suction chamber 111 increases, and the suction chamber 111 is connected to the tube. The through hole 7 and the connecting flow channel 112 are connected to the sealed chamber (the sealed chamber formed by the sealing ring 11, the mounting shell 4 and the wrist skin), and the pressure in the sealed chamber is reduced, so that the sealing ring 11 is used to adsorb the mounting shell 4 to the wrist skin. When the shell 1 and the wrist move relative to each other later, the shell 1 does not directly contact the power member 3 and the mounting shell 4. The shell 1 squeezes the squeezing ring 9 to deform, while the power member 3 and the mounting shell 4 remain relatively still with the wrist skin under the action of the sealing ring 11. In this way, the probability of low monitoring accuracy caused by the movement of the skin relative to the skin electrode 5 and the optical sensor 6 during monitoring is reduced.
[0030] Please refer to Figure 3-Figure 5 and Fig. 9 , and also includes: a reset ring 13, fixedly connected to one side of the mounting hole 104 close to the magnet sheet 2, the minimum inner diameter of the reset ring 13 is equal to the outer diameter of the power piece 3; in the vertical direction, the distance between the reset ring 13 and the protrusion 103 is greater than the height of the power piece 3.
[0031] In the above scheme, the reset ring 13 is used to guide the power piece 3 so that the power piece 3 can be completely reset and located in the middle of the magnet sheet 2, thereby preventing the extrusion ring 9 from having irregular circumferential deformation during the period when no monitoring is performed, thereby ensuring the effect of the extrusion ring 9 flattening the skin during the downward movement; an inclined annular surface is provided on the inner side of the reset ring 13, and the inner diameter of the inclined annular surface gradually increases in the vertical downward direction. An annular inclined surface can be provided on the upper side of the power piece 3, so that the contact position between the power piece 3 and the reset ring 13 is smoother, which is conducive to the sliding of the power piece 3 along the reset ring 13; in the vertical direction, the distance between the reset ring 13 and the protrusion 103 is greater than the height of the power piece 3, so that after the power piece 3 is moved downward under the action of the magnetic repulsion force, the upper side of the power piece 3 can be completely moved out of the reset ring 13, so as to prevent the shell 1 from squeezing the power piece 3 to move through the reset ring 13 when the shell 1 moves relative to the wrist skin and the mounting shell 4 is stationary relative to the wrist skin, causing the skin electrode 5 and the optical sensor 6 on the mounting shell 4 to move out of position with the wrist skin.
[0032] Please refer to Figure 4-Figure 6The extrusion ring 9 and the sealing ring 11 are both made of elastic and light-proof materials.
[0033] In the above scheme, the light-proof properties of the extrusion ring 9 and the sealing ring 11 are utilized to isolate the optical sensor 6 from the external environment, thereby reducing the probability that the light in the external environment affects the monitoring result of the optical sensor 6; the optical sensor 6 monitors the heart rate and blood oxygen through the difference between the incident light and the reflected light, so if the light in the external environment enters between the optical sensor 6 and the skin, it will cause the monitoring result of the optical sensor 6 to deviate.
[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
