Description

Technical Field

[0001] The utility model relates to the technical field of intelligent wearable devices, in particular to an intelligent ring.

Background Art

[0002] With the increasing improvement of people's living standards, the choice of intelligent wearable products is becoming more and more abundant. The intelligent ring is a small intelligent wearable device extended on the basis of intelligent bracelets and watches. Due to its characteristics of light weight, small size, convenient and beautiful wearing, it is loved by more and more users.

[0003] The intelligent rings in the prior art all have a PPG (photoplethysmography) module for monitoring blood oxygen saturation. Blood oxygen saturation is an important parameter for measuring the oxygen-carrying capacity of human blood and is also one of the important basic data in clinical medicine. The PPG module for monitoring blood oxygen saturation in the prior art irradiates light on the human skin by setting an LED, and then receives the light reflected by the human body through a PD to monitor. However, the monitored result has a large error and cannot accurately monitor the blood oxygen saturation of the human body; the devices with higher monitoring accuracy are not portable, which is very inconvenient.

Content of the Utility Model

[0004] At present, the prior art has technical problems of large monitoring error and inconvenient monitoring. The utility model provides an intelligent ring for solving the above problems simultaneously.

[0005] An intelligent ring for wearing on a finger to monitor human health, comprising a housing, a filling part and a circuit component. The circuit component includes a PCB board, a light receiving unit and a first light emitting unit. The housing encloses an annular cavity. The circuit component is arranged in the annular cavity. The light receiving unit is arranged on one side of the PCB board facing the filling part. The first light emitting unit and the light receiving unit are arranged on the PCB board at intervals, and the included angle between the first light emitting unit and the light receiving unit relative to the center of the circle of the housing is 45° to 170°.

[0006] Compared with the prior art, the intelligent ring realizes the monitoring of the wearer's blood oxygen saturation by setting the light receiving unit and the first light emitting unit. Moreover, due to the setting of the distance between the first light emitting unit and the light receiving unit, the transmission type light signal reception is realized, thereby improving the accuracy of blood oxygen saturation monitoring.

Specific Embodiments

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0014] Please refer to Figure 1 and Figure 2 , the intelligent ring 100 includes a housing 1, a filling portion 3, and a circuit component 5. The housing 1 encloses an annular cavity 101, and the circuit component 5 is disposed in the annular cavity 101. The intelligent ring 100 is integrally circular and not much different from an ordinary ring, mainly facilitating the wearer to wear the intelligent ring 100 on the finger.

[0015] The housing 1 can be composed of one material or two or more materials, and the materials include common metal materials, alloy materials, ceramic materials, plastic materials, or transparent soft rubber materials, etc. In this embodiment, as Figure 3As shown, the housing 1 includes a first housing 11, a second housing 13 and a connecting housing 15. The connecting housing 15 is disposed between the first housing 11 and the second housing 13. Among them, the material of the connecting housing 15 is different from that of the first housing 11 and the second housing 13. The first housing 11 and the second housing 13 can select metal materials, and the connecting housing 15 selects a transparent soft rubber material, which is convenient for the wearer to observe the content or light displayed inside the smart ring 100.

[0016] The filling part 3 is mainly composed of a soft rubber material. The finger of the wearer is in full contact with the filling part 3 to ensure the comfort of wearing. The filling part 3 cooperates with the housing 1. The housing 1, the circuit assembly 5 and the filling part 3 are arranged in sequence from the outside to the inside, and the circuit assembly 5 is accommodated between the housing and the filling part. This setting is beneficial to protecting the circuit assembly 5. Generally, the circuit assembly 5 is installed first and then the filling part 3 is injected, so that the filling part 3 fits well with the housing 1 and the circuit assembly 5. The filling part 3 can ensure the stable position of the circuit assembly 5 and will not slide relative to the housing 1.

[0017] Please refer to Figure 4 , the circuit assembly 5 includes a PCB board 51, a light receiving unit 52, a first light emitting unit 54, a control unit 55 and a battery unit 58. The light receiving unit 52 and the first light emitting unit 54 are both disposed on the side of the PCB board 51 facing the filling part 3. The first light emitting unit 54 and the light receiving unit 52 are spaced apart on the PCB board 51, and the included angle B between the first light emitting unit 54 and the light receiving unit 52 relative to the center of the smart ring 100 is set to 45° to 170°. Since the finger of the wearer is closely attached to the filling part 3, when the first light emitting unit 54 emits light, the reflected light cannot enter the light receiving unit 52, and the light receiving unit 52 receives the light signal transmitted through the finger. The accuracy of the light monitored by the transmitted light is high, which is more conducive to monitoring the human body's blood oxygen saturation.

[0018] When the included angle B is less than 45°, the light receiving unit 52 mainly receives the light signal reflected by the finger or the signal directly irradiated by the first light emitting unit 54, which is likely to cause interference and reduce the accuracy of monitoring. When the included angle B is less than 170°, due to the occlusion of the bones in the wearer's finger, the intensity of the light signal received by the light receiving unit 52 decreases, and the efficiency of the smart ring 100 in monitoring the human body's blood oxygen saturation decreases, which will further affect the monitoring accuracy. According to the settings of different angles of the included angle, the blood oxygen saturation of the same adult human body is measured multiple times, the average value is calculated and compared with the average value detected by a medical instrument. The error situation of monitoring the human body's blood oxygen saturation is shown in Table 1 below:

[0019] Table 1 Monitoring error situation table

[0020] Angle B 0° 15° 30° 45° 60° 75° 90° Monitoring average value 97.40％ 97.33％ 97.38％ 97.63％ 97.73％ 97.76％ 97.83％ Actual average value 98％ 98％ 98％ 98％ 98％ 98％ 98％ Error -0.60％ -0.67％ -0.62％ -0.37％ -0.27％ -0.24％ -0.17％ Angle B 105° 120° 135° 150° 165° 170° 180° Monitoring average value 97.85％ 98.06％ 98.17％ 98.20％ 98.27％ 98.33％ 98.73％ Actual average value 98％ 98％ 98％ 98％ 98％ 98％ 98％ Error -0.15％ 0.06％ 0.17％ 0.20％ 0.27％ 0.33％ 0.73％

[0021] As can be seen from the data in the above table, when the included angle B is within the range of 45° to 170°, the error is small; when the angle of the included angle B is small, due to the interference of the direct irradiation of the light signal, the monitoring value will be lower than the actual value. As the included angle B continues to increase, due to the increased transmission distance, the monitoring value will also increase correspondingly. When it exceeds 170°, due to the influence of the wearer's finger bones, the error increases.

[0022] In this embodiment, the circuit component 5 further includes a second light emitting unit 53. The second light emitting unit 53 is disposed on the PCB board 51 and is located between the light receiving unit 52 and the first light emitting unit 54. The included angle A between the second light emitting unit 53 and the light receiving unit 52 relative to the center of the smart ring 100 can be set to 0° to 45° to enable the second light emitting unit 53 to emit light to the wearer's finger, and the light is emitted through the wearer's finger skin and reaches the light receiving unit 52, thereby realizing the monitoring of the wearer by using the reflection principle.

[0023] When the included angle A is greater than or equal to 45°, the light signal mainly transmitted through the finger emitted by the second light emitting unit 53 is received by the light receiving unit 52. Although the monitoring accuracy increases, the power consumption is large and it is not conducive to long-term operation.

[0024] It should be specifically noted here that the included angle A includes 0° but does not include 45°; the "between" does not mean being located at the middle of the light receiving unit 52 and the first light emitting unit 54, nor at a certain point on the line connecting the two; it is mainly used to distinguish the positional relationship of the second light emitting unit 53 and the first light emitting unit 54 relative to the light receiving unit 52 respectively. In addition, both the first light emitting unit 54 and the light receiving unit 52 include at least one light emitting diode, and the light receiving unit 52 includes at least one photodiode. Therefore, it can be understood that the light emitting diodes with the included angle positional relationship between 0° and 45° all belong to the second light emitting unit 53, and those with the included angle positional relationship between 45° and 170° all belong to the first light emitting unit 54. Wherein, the included angle positional relationship of 0° does not mean that the light emitting diode and the photodiode completely overlap, but rather an angular overlap in the arc direction of the smart ring 100, and they are arranged side by side in the width direction of the smart ring 100.

[0025] The light emitting diodes in the first light emitting unit 54 mainly use red light and infrared light for monitoring blood oxygen saturation. The light emitting diodes in the second light emitting unit 53 include red light, green light and infrared light, and can be used for monitoring blood oxygen saturation and measuring heart rate. The first light emitting unit 54, the second light emitting unit 53 and the light receiving unit 52 cooperate with each other to simultaneously realize monitoring blood oxygen saturation and measuring heart rate. Moreover, the second light emitting unit 53 can be continuously turned on for monitoring with low power consumption. When it is necessary to improve the monitoring accuracy, the control unit 55 controls the first light emitting unit 54 to emit light signals, thereby improving the accuracy of monitoring blood oxygen saturation.

[0026] Please refer to Figure 5 , the control unit 55 is connected to the light receiving unit 52, the first light emitting unit 54 and the second light emitting unit 53, controls the first light emitting unit 54 and the second light emitting unit 53 to emit light signals, and analyzes and processes the signals received by the light receiving unit 52. During daily wearing, the control unit 55 mainly controls the second light emitting unit 53 to emit light signals, and the signals received by the light receiving unit 52 are used to display the preliminary monitoring results; when the wearer needs to accurately measure blood oxygen saturation, by applying a signal to the smart ring 100, the control unit 55 controls the first light emitting unit 54 to emit light signals, so as to obtain a more accurate monitoring result. Since long-term use of transmissive monitoring consumes a large amount of power, through this setting method, the wearer can control the monitoring accuracy at any time and place while achieving the effect of energy saving and reducing the charging frequency of the wearer.

[0027] The overall shape of the battery unit 58 is annular, adapted to the outer shell 1 and the annular cavity 101. The battery unit 58 is connected to the control unit 55 to provide power for the smart ring 100.

[0028] The PCB board 51 includes a plurality of rigid circuit boards 511 and flexible connection parts 513. The flexible connection parts 513 are arranged between the rigid circuit boards 511 to fit the annular outer shell 1 and facilitate the installation of the light receiving unit 52, the second light emitting unit 53, the first light emitting unit 54 and the control unit 55. In this embodiment, the rigid circuit board 511 includes a first board body 5111, a second board body 5113 and a third board body 5115. The light receiving unit 52 is arranged on the first board body 5111, the second light emitting unit 53 is arranged on the second board body 5113, and the first light emitting unit 54 is arranged on the third board body 5115. Through the arrangement of the first board body 5111, the second board body 5113 and the third board body 5115, the relative positions of the light receiving unit 52, the second light emitting unit 53 and the first light emitting unit 54 are fixed stably. Among them, the circuit assembly 5 further includes a support structure 56. The support structure 56 is opposite to the first light emitting unit 54 and is arranged between the third board body 5115 and the outer shell 1. The support structure 56 supports the third board body 5115, so that the third board body 5115 is arranged as parallel as possible to the first board body 5111, or the light with the highest power of the first light emitting unit 54 is arranged at an angle as much as possible to be emitted towards the light receiving unit 52. Since the first light emitting unit 54 is arranged on the side of the third board body 5115 facing the filling part 3, this arrangement makes the energy of the light emitted by the first light emitting unit 54 reaching the light receiving unit 52 through the transmission of the finger maximized. It not only improves the measurement accuracy but also saves energy. It should be noted here that the angle at which the support structure 56 supports the third board body 5115 is related to the relative position distance and angle between the light receiving unit 52 and the first light emitting unit 54, so no specific limitation is made.

[0029] In this embodiment, the rigid circuit board 511 further includes a fourth board body 5117, and the control unit 55 is disposed on the fourth board body 5117 to stabilize the position of the control unit 55. Wherein, the first board body 5111, the second board body 5113, the fourth board body 5117 and the third board body 5115 are sequentially connected by the flexible connection portion 513, and the light receiving unit 52, the second light emitting unit 53, the control unit 55 and the first light emitting unit 54 are sequentially arranged. The control unit 55 is disposed between the second light emitting unit 53 and the first light emitting unit 54, facilitating the connection and control of the emission unit 551 with the second light emitting unit 53 and the first light emitting unit 54 to emit light signal. And through the

[0030] The fourth board body 5117 separates the third board body 5115 from the first board body 5111 and the second board body 5113, avoiding mutual interference between the second light emitting unit 53 and the first light emitting unit 54, and ensuring that the light emitted by the first light emitting unit 54 is transmitted to the light receiving unit 52 instead of being reflected into the light receiving unit 52.

[0031] Certainly, in another embodiment, the arrangement order of the light receiving unit 52, the second light emitting unit 53, the control unit 55 and the first light emitting unit 54 can be adjusted to a certain extent, as long as the distance control between the first board body 5111 and the second board body 5113 and the fourth board body 5117 meets the requirement that the included angles of the light receiving unit 52, the second light emitting unit 53 and the first light emitting unit 54 relative to the center of the smart ring 100 conform to the effect of reflection and transmission type light signal transmission, and ensure that there is no interference between the second light emitting unit 53 and the first light emitting unit 54. In another embodiment, the first board body 5111 and the second board body 5113 can be the same board body, that is, when the included angle A is a low angle, the second light emitting unit 53 and the light receiving unit 52 can be disposed on the same board body. In addition, the control unit 55 can be disposed not only on the fourth board body 5117, but also on the first board body 5111, the second board body 5113 and the third board body 5115, without affecting the control of the control unit 55 over the second light emitting unit 53 and the first light emitting unit 54, and the analysis and processing of the light signal received by the light receiving unit 52.

[0032] In this embodiment, the circuit component 5 further includes a light-shielding structure 57. The light-shielding structure 57 is disposed on the same side of the first plate body 5111 relative to the light-receiving unit 52, and the light-shielding structure 57 is provided with a light-transmitting hole 571. The light signals reflected by the light emitted by the second light-emitting unit 53 and the light signals transmitted by the light emitted by the first light-emitting unit 54 both enter the light-receiving unit 52 through the light-transmitting hole 571. Since the distance between the first plate body 5111 and the second plate body 5113 is small in order for the light-receiving unit 52 to receive the reflected light signal, there is a situation where the light directly emitted by the second light-emitting unit 53 irradiates the light-receiving unit 52, resulting in a large monitoring error. The setting of the light-shielding structure 57 blocks the light signal directly irradiated by the second light-emitting unit 53, ensuring that the signal received by the light-receiving unit 52 comes from the reflected light signal.

[0033] Of course, in another embodiment, the light-shielding structure 57 may also be disposed on the same side of the second plate body 5113 relative to the second light-emitting unit 53, and the direct irradiation of light can also be blocked. Or a plurality of light-shielding structures 57 are provided, which are respectively disposed relative to the light-receiving unit 52, the second light-emitting unit 53, and the first light-emitting unit 54. The signal interference between the second light-emitting unit 53 and the first light-emitting unit 54 can be avoided simultaneously.

[0034] The filling portion 3 is provided with a plurality of protruding portions 31. The protruding portions 31 are disposed opposite to the light-receiving unit 52, the second light-emitting unit 53, and the first light-emitting unit 54. The protruding portions 31 have a good light-gathering effect, thereby improving the transmission efficiency of the light signal and saving energy. And the protruding portions 31 have the function of increasing friction and preventing falling during the movement of the wearer.

[0035] In this embodiment, the filling portion 3 is also provided with a protruding portion 31 corresponding to the position of the control unit 55, which can achieve a certain symmetrical effect, increase the comfort of the wearer during wearing, and at the same time increase the anti-slip effect.

[0036] The basic principle of the smart ring 100 provided by this application for monitoring blood oxygen saturation is summarized as follows:

[0037] The wearer wears the smart ring 100 on the finger, and the finger fits well with the filling portion 3;

[0038] The control unit 55 controls the second light-emitting unit 53 to continuously emit light signals, and the light signals are reflected by the finger skin and then reach the light-receiving unit 52;

[0039] The control unit 55 analyzes and processes the signals received by the light-receiving unit 52;

[0040] The wearer applies a control signal, enabling the transmitting unit 551 to control the first light-emitting unit 54 to emit a light signal, which is transmitted through the finger skin to the light-receiving unit 52, and simultaneously temporarily turning off the light signal emitted by the second light-emitting unit 53;

[0041] The control unit 55 analyzes and processes the signal received by the light-receiving unit 52;

[0042] After the monitoring is completed, the transmitting unit 551 turns off the light signal emitted by the first light-emitting unit 54 and controls the second light-emitting unit 53 to continuously emit a light signal.

[0043] Compared with the prior art, the intelligent ring 100 provided by the present utility model realizes the monitoring of the blood oxygen saturation of the wearer by setting the light-receiving unit 52, the second light-emitting unit 53 and the first light-emitting unit 54. Moreover, due to the setting of the distances between the first light-emitting unit 54 and the second light-emitting unit 53 and the light-receiving unit 52, the combination of reflective and transmissive light signal reception is realized, thereby improving the accuracy of the blood oxygen saturation monitoring of the intelligent ring 100.

[0044] The above are only the embodiments of the present utility model. It should be noted here that for those of ordinary skill in the art, improvements can be made without departing from the creative concept of the present utility model, but these all belong to the protection scope of the present utility model.
