TECHNICAL FIELD

[0001] The present application relates to a device for promoting blood flow rate of human body; in particular, it relates to a radio wave generating device for promoting blood flow rate of ophthalmic artery and central retinal artery through radio wave. BACKGROUND

[0002] Blood circulation is essential for maintaining physical health and body function. However, many people face the problem of poor blood circulation, leading to various health problems such as muscle soreness, dizziness, cold hands and feet, weakness, etc. One of the reasons is that the blood flow rate is too slow, resulting in a decrease in the efficiency of transporting nutrients in the blood.

[0003] Taking the blood flow rate of the eye blood vessels as an example, in modern life, using a smart phone has become an indispensable part of people's daily life. However, staring at the screen of this type of electronic device for a long time can easily cause eye fatigue, one of the reasons being the decrease in blood flow rate of the eye blood vessels.

[0004] Currently, there are some solutions, such as massage, hot compress, etc., which can improve human blood circulation and increase blood flow rate. However, these solutions still have some limitations, such as the user needs to stop the work at hand to massage, hot compress, etc., which is still inconvenient for the user. SUMMARY

[0005] Therefore, the purpose of the present application is to provide a radio wave generating device for promoting blood flow rate of ophthalmic artery and central retinal artery through radio wave.

[0006] In order to achieve the above-mentioned purpose, the present application provides a radio wave generating device for promoting blood flow rate of ophthalmic artery and central retinal artery; the radio wave generating device comprises a plurality of radio wave generating circuits and a control module, wherein the plurality of radio wave generating circuits comprises a first radio wave generating circuit and a second radio wave generating circuit, wherein:

[0007] The first radio wave generating circuit is connected to a first antenna, and the first radio wave generating circuit can be controlled to start, and the first radio wave generating circuit generates a first radio wave and transmits it through the first antenna when starting, wherein the first radio wave has a first frequency of fundamental frequency and a plurality of first harmonics corresponding to the first frequency of fundamental frequency; wherein the first frequency of fundamental frequency is 10 MHz or more;

[0008] The second radio wave generating circuit is connected to a second antenna. The second radio wave generating circuit can be controlled to start. When the second radio wave generating circuit is started, it generates a second radio wave and transmits it through the second antenna. The second radio wave has a second fundamental frequency and a plurality of second harmonics corresponding to the second fundamental frequency. The second fundamental frequency is more than 10 times the first fundamental frequency.

[0009] The control module is electrically connected to the plurality of radio wave generating circuits. The control module controls the first radio wave generating circuit to start and controls the second radio wave generating circuit to start, so as to generate the first radio wave and the second radio wave.

[0010] The advantage of this invention is that the radio waves emitted by the radio wave generating device simultaneously possess the fundamental frequency of the first frequency, the plurality of first harmonics, the fundamental frequency of the second frequency, and the plurality of second harmonics, thereby achieving the technical effect of increasing the blood flow velocity of the ophthalmic artery and the central retinal artery. Users can promote blood flow without stopping their work by using the radio waves emitted by the radio wave generating device. Attached Figure Description

[0065] To more clearly illustrate the present invention, preferred embodiments are described in detail below with reference to the accompanying drawings. Please refer to... Figures 1 to 3 As shown, a radio wave generating device 1 according to a first preferred embodiment of the present invention is used to generate radio waves to promote blood flow velocity in the ophthalmic artery and the central retinal artery. The radio wave generating device 1 includes a plurality of radio wave generating circuits 100 and a control module 40.

[0066] In this embodiment, the plurality of radio wave generating circuits 100 include at least a first radio wave generating circuit 10 and a second radio wave generating circuit 20.

[0067] The first radio wave generating circuit 10 is connected to a first antenna 30, and the first radio wave generating circuit 10 can be controlled to start or stop. When the first radio wave generating circuit 10 is controlled to start, it generates a first radio wave and transmits it through the first antenna 30. The first radio wave has a fundamental frequency (or first harmonic) of a first frequency and a plurality of first harmonics (i.e., higher harmonics) corresponding to the fundamental frequency. When the first radio wave generating circuit 10 is controlled to stop, it stops generating the first radio wave. The plurality of first harmonics are N times the first frequency, where N is an integer greater than or equal to 2. The fundamental frequency of the first frequency is at least 10 MHz, preferably between 10 MHz and 70 MHz.

[0068] The fundamental frequency of the first frequency is 36MHz, meaning that the plurality of first harmonics (higher harmonics) are at least 4th harmonics, i.e., the frequencies of the plurality of first harmonics are 72MHz, 108MHz, and 144MHz, respectively. Figure 4 The image shows the spectrum measured using a spectrum analyzer. The higher the harmonic order, the lower its intensity. The peak intensities of the frequency peaks at 36MHz, 72MHz, 108MHz, and 144MHz are -6.23dBm, -24.85dBm, -34.56dBm, and -37.18dBm, respectively. Preferably, the higher harmonic is the 10th harmonic; more preferably, in this embodiment, the higher harmonic is the 12th harmonic, with a frequency of 432MHz.

[0069] The second radio wave generating circuit 20 is connected to a second antenna 32, and the second radio wave generating circuit 20 can be controlled to start or stop. When the second radio wave generating circuit 20 is controlled to start, it generates a second radio wave and transmits it through the second antenna 32. The second radio wave has a fundamental frequency (first harmonic) of a second frequency and a plurality of second harmonics (higher harmonics) corresponding to the fundamental frequency. The plurality of second harmonics are N times the second frequency, where N is an integer greater than or equal to 2. The fundamental frequency of the second frequency is at least 10 times the fundamental frequency of the first frequency, preferably between 10 and 13 times.

[0070] In this embodiment, the fundamental frequency of the second frequency is 433MHz, that is, the plurality of second harmonics (higher harmonics) are at least 4th harmonics, i.e., the frequencies of the plurality of second harmonics are 866MHz, 1299MHz, and 1732MHz, respectively. Preferably, it is a 10th harmonic, more preferably a 12th harmonic. The fundamental frequency and second harmonics of the second radio wave are to compensate for the frequencies not present and / or the first harmonics with lower intensity in the first radio wave. In particular, the fundamental frequency of the second frequency is 433MHz, which is approximately 12.03 times the fundamental frequency of the first frequency, and its frequency is close to that of the 12th harmonic of 36MHz (432MHz), thus perfectly compensating for the intensity of 432MHz.

[0071] The fundamental frequency of the second frequency is different from the fundamental frequency of the first frequency. In this embodiment, the fundamental frequency of the second frequency is greater than the fundamental frequency of the first frequency, and the frequency range of the frequency peak of the fundamental frequency of the second frequency in the frequency domain covers the frequency range of the frequency peak of one of the plurality of first harmonics in the frequency domain. That is, the frequency peak of the fundamental frequency of the second frequency overlaps with the frequency peak of one of the plurality of first harmonics. Preferably, the half-width at half-maximum (WHM) of the frequency peak of the fundamental frequency of the second frequency covers the frequency range of the frequency peak of one of the plurality of first harmonics. For example, if the fundamental frequency of the second frequency is 433MHz, the WHM of its frequency peak covers the frequency range of the 12th harmonic (432MHz) of 36MHz in the frequency domain, thus achieving the effect of supplementing the intensity of 432MHz.

[0072] The control module 40 is electrically connected to the first radio wave generating circuit 10 and the second radio wave generating circuit 20 of the plurality of radio wave generating circuits 100. The control module 40 is electrically connected to a power supply 50, which provides power; the power supply 50 can be a battery (e.g., a rechargeable battery) or an external power source. The control module 40 controls the first radio wave generating circuit 10 to start or stop, and controls the second radio wave generating circuit 20 to start or stop. When the control module 40 controls the first radio wave generating circuit 10 to start and the second radio wave generating circuit 20 to start, the first radio wave and the second radio wave are emitted from the first antenna 30 and the second antenna 32, respectively. Preferably, the control module 40 controls the first radio wave generating circuit 10 and the second radio wave generating circuit 20 to start simultaneously, so that the radio waves emitted by the radio wave generating device 1 simultaneously contain the first radio wave and the second radio wave; that is, the radio waves simultaneously have the fundamental frequency of the first frequency, the plurality of first harmonics, the fundamental frequency of the second frequency, and the plurality of second harmonics.

[0073] In this embodiment, the first radio wave generating circuit 10 has a first power input terminal 102, and the second radio wave generating circuit 20 has a second power input terminal 202. The first power input terminal 102 and the second power input terminal 202 are used to input a working voltage V+, so as to start the first radio wave generating circuit 10 and the second radio wave generating circuit 20.

[0074] To provide the operating voltage V+ to the first radio wave generating circuit 10 and the second radio wave generating circuit 20, in this embodiment, the control module 40 includes a controller 42, a power supply circuit 44, and a switching element 46. The controller 42 may be, for example, a microcontroller. The controller 42 and the power supply circuit 44 are electrically connected to the power supply 50, and the power supply 50 provides power to the controller 42 and the power supply circuit 44. The power supply circuit 44 is used to convert the voltage of the power supply 50 into the operating voltage V+. The power supply circuit 44 has a power output terminal 442 from which the operating voltage V+ is output. In this embodiment, the power supply circuit 44 is a boost circuit.

[0075] The switching element 46 has a first terminal 462, a second terminal 464, and a control terminal 466. The switching element 46 can be a transistor, such as a MOSFET or a BJT. Taking an n-channel MOSFET as an example, the first terminal 462 is the drain, the second terminal 464 is the source, and the control terminal 466 is the gate. The control terminal 466 is used to receive a control signal to turn on the first terminal 462 and the second terminal 464. The control signal can be a high-voltage level signal. When the control terminal 466 receives a low-voltage level signal, the first terminal 462 and the second terminal 464 are turned off. The first terminal of the switching element 46 is electrically connected to the power output terminal 442 of the power supply circuit 44, the second terminal 464 is electrically connected to the first power input terminal 102 of the first radio wave generating circuit 10 and the second power input terminal 202 of the second radio wave generating circuit 20, and the control terminal 466 is electrically connected to the controller 42.

[0076] The controller 42 outputs the control signal to the control terminal 466 of the switching element 46, and the first terminal 462 and the second terminal 464 of the switching element 46 are connected, that is, the working voltage V+ output by the power output terminal 442 can be supplied to the first power input terminal 102 and the second power input terminal 202 to simultaneously start the first radio wave generating circuit 10 and the second radio wave generating circuit 20.

[0077] In this embodiment, the controller 42 can be electrically connected to a start switch 52. The start switch 52 generates a start signal when touched by a user, and the controller 42 outputs a control signal based on the start signal. For example, the user presses and holds the start switch 52 for 0.5 seconds to generate the start signal. Pressing and holding the start switch 52 again for 0.5 seconds generates a stop signal. When the controller 42 determines that it has received the stop signal, it stops outputting the control signal to the control terminal 466 of the switching element 46, thereby cutting off the connection between the first terminal 462 and the second terminal 464 of the switching element 46, and thus stopping the first radio wave generating circuit 10 and the second radio wave generating circuit 20.

[0078] Please cooperate. Figure 2 The first radio wave generating circuit 10 includes a crystal oscillator (hereinafter referred to as the first crystal oscillator 12), a first amplifier circuit 14, and a second amplifier circuit 16. The first crystal oscillator 12 is an active crystal oscillator. The first crystal oscillator 12, the first amplifier circuit 14, and the second amplifier circuit 16 are electrically connected to the first power input terminal 102 to receive the operating voltage V+ and operate accordingly.

[0079] The first crystal oscillator 12 generates an electrical signal with a fundamental frequency of the first frequency, and has an output terminal OUT for outputting the electrical signal with the fundamental frequency of the first frequency. The first crystal oscillator 12 also has a power supply terminal VCC, a ground terminal GND, and an output enable terminal OE. The ground terminal GND is connected to a ground terminal G, and the output enable terminal OE is floating. The first amplifier circuit 14 is electrically connected to the first crystal oscillator 12 and resonates and amplifies the electrical signal with the fundamental frequency of the first frequency to output a resonant signal. The resonant signal has the fundamental frequency of the first frequency and the plurality of first harmonics corresponding to the fundamental frequency of the first frequency. The second amplifier circuit 16 is electrically connected to the first amplifier circuit 14 and the first antenna 30. The second amplifier circuit 16 amplifies and / or re-resonates the resonant signal to generate the first radio wave and transmits it through the first antenna 30.

[0080] More specifically, the first amplifier circuit 14 includes a first inductor L1a, a first capacitor C1a, and a first transistor Q1a. A first terminal of the first inductor L1a is electrically connected to the first power input terminal 102. In this embodiment, the first terminal of the first inductor L1a is electrically connected to the first power input terminal 102 through a current-limiting resistor RL. In practice, the current-limiting resistor RL can also be omitted. A second terminal of the first inductor L1a is electrically connected to a first terminal of the first capacitor C1a and the power supply terminal VCC of the first crystal oscillator 12. The first transistor Q1a has a first terminal, a second terminal, and a third terminal. In this embodiment, the first transistor is a BJT, with the first terminal being the collector, the second terminal being the emitter, and the third terminal being the base. However, this is not a limitation, and the first transistor Q1a can also be a MOSFET. The first terminal of the first transistor Q1a is electrically connected to the second terminal of the first inductor L1a and the first terminal of the first capacitor C1a. The second terminal of the first transistor Q1a is electrically connected to the ground terminal G. The third terminal of the first transistor Q1a is electrically connected to the output terminal OUT of the first crystal oscillator 12 and is electrically connected to the first power input terminal 102 through a resistor R, or electrically connected to the first power input terminal 102 through the resistor R and the current-limiting resistor RL. The first amplifier circuit 14 amplifies the fundamental frequency electrical signal of the first frequency through the first transistor Q1a and generates the resonant signal by the resonance between the first inductor and the first capacitor.

[0081] The second amplifier circuit 16 includes a second inductor L2a, a second capacitor C2a, and a second transistor Q2a. A first terminal of the second inductor L2a is electrically connected to the first power input terminal 102, and a second terminal of the second inductor L2a is electrically connected to a first terminal of the second capacitor C2a. The second transistor Q2a has a first terminal, a second terminal, and a third terminal. In this embodiment, the second transistor Q2a is a BJT, with the first terminal being the collector, the second terminal being the emitter, and the third terminal being the base. However, this is not a limitation, and the second transistor Q2a can also be a MOSFET. The first terminal of the second transistor Q2a is electrically connected to the second terminal of the second inductor L2a and the first terminal of the second capacitor C2a. The second terminal of the second transistor Q2a is electrically connected to the ground terminal G. The third terminal of the second transistor Q2a is electrically connected to the second terminal of the first capacitor C1a. A second terminal of the second capacitor C2a is electrically connected to the first antenna. The second amplifier circuit 16 amplifies the resonant signal through the second transistor Q2a and the second inductor L2a and the second capacitor C2a resonate, and outputs the first radio wave and transmits it through the first antenna 30.

[0082] Optionally, the first and second terminals of the first capacitor C1a are respectively connected to filter capacitors Cf1 and Cf2 to filter out noise. The first radio wave generating circuit 10 may include an overvoltage protection element P1, electrically connected between the first terminal of the second transistor Q2a and the ground terminal G. The overvoltage protection element P1 is used to form a voltage relief path when the voltage at the first terminal of the second transistor Q2a is greater than a predetermined voltage. The overvoltage protection element P1 may be, for example, a bidirectional or unidirectional transient voltage suppressor diode (TVS diode) for electrostatic discharge protection. The first radio wave generating circuit 10 may include a surge protection element P2, electrically connected between the second terminal of the second capacitor C2a and the ground terminal G. The surge protection element P2 is used to form a voltage relief path when the second antenna 32 generates a surge. The surge protection element P2 may be, for example, a gas discharge tube (GDT) for surge protection.

[0083] Please cooperate. Figure 3 The second radio wave generating circuit 20 has a structure substantially the same as the first radio wave generating circuit 10. The second radio wave generating circuit 20 includes a crystal oscillator (hereinafter referred to as the second crystal oscillator 22), a first amplifier circuit 24, and a second amplifier circuit 26. The second crystal oscillator 22 is an active crystal oscillator. The second crystal oscillator 22, the first amplifier circuit 24, and the second amplifier circuit 26 are electrically connected to the second power input terminal 202 to receive the operating voltage V+ and operate accordingly. The second crystal oscillator 22 generates an electrical signal having a fundamental frequency of the second frequency, and the second crystal oscillator 22 has an output terminal OUT, which is used to output the electrical signal of the second fundamental frequency.

[0084] The first amplifier circuit 24 is electrically connected to the second crystal oscillator 22 and resonates and amplifies an electrical signal having a fundamental frequency of the second frequency to output a resonant signal, the resonant signal having a fundamental frequency of the second frequency and the plurality of second harmonics corresponding to the fundamental frequency of the second frequency. The second amplifier circuit 26 is electrically connected to the first amplifier circuit 24 and the second antenna 32, the second amplifier circuit 26 amplifies the resonant signal and / or resonates it again to generate the second radio wave and transmit it through the second antenna 32.

[0085] More specifically, the first amplifier circuit 24 includes a first inductor L1b, a first capacitor C1b, and a first transistor Q1b. The first amplifier circuit 24 is substantially the same as the first amplifier circuit 14 of the first radio wave generating circuit 10, except that in this embodiment, the first terminal of the first transistor Q1b is electrically connected to the second terminal of the first inductor L1b and the output terminal OUT of the second crystal oscillator 22. The output enable terminal OE of the second crystal oscillator 22 is connected to the third terminal of the first transistor Q1b and the resistor R. The power supply terminal VCC is connected to the ground terminal GND. The connection relationships of the other components of the first amplifier circuit 24 of the second radio wave generating circuit 20 are the same as those of the first amplifier circuit 14 of the first radio wave generating circuit 10, and will not be repeated here. In one embodiment, the second crystal oscillator 22 may also adopt the same connection method as the first crystal oscillator 12.

[0086] The first amplifier circuit 24 amplifies the fundamental frequency electrical signal of the second frequency through the first transistor Q1b and generates resonance between the first inductor L1b and the first capacitor C1b, and outputs the resonant signal.

[0087] The second amplifier circuit 26 of the second radio wave generating circuit 20 includes a second inductor L2b, a second capacitor C2b, and a second transistor Q2b. The connection relationship between the second inductor L2b, the second capacitor C2b, and the second transistor Q2b is roughly the same as that of the second amplifier circuit 16 of the first radio wave generating circuit 10, except that the antenna connected to the second terminal of the second capacitor C2b is the second antenna 32, which will not be described in detail here. The second amplifier circuit 26 amplifies the resonant signal through the second transistor Q2b and generates resonance between the second inductor L2b and the second capacitor C2b, thereby outputting the second radio wave and transmitting it through the second antenna 32.

[0088] The second radio wave generating circuit 20 may also include filter capacitors Cf1 and Cf2, overvoltage protection element P1 and surge protection element P2, just like the first radio wave generating circuit 10.

[0089] Since both the first radio wave generating circuit 10 and the second radio wave generating circuit 20 employ two-stage amplification, the intensity of the fundamental frequency with the first frequency and the plurality of first harmonics in the first radio wave can be increased, as can the intensity of the fundamental frequency with the second frequency and the plurality of second harmonics in the second radio wave.

[0090] The radio waves emitted by the radio wave generating device simultaneously possess the fundamental frequency of the first frequency, the plurality of first harmonics, the fundamental frequency of the second frequency, and the plurality of second harmonics, which can achieve the technical effect of promoting blood flow velocity in the ophthalmic artery and the central retinal artery.

[0091] Figure 5 This is a comparative graph showing the effect of the radio wave generating device 1 in this embodiment on the ophthalmic artery systolic blood flow velocity (OA-PSV) of the subject. Figure 6 This is a comparative graph showing the effect of the radio wave generating device 1 of this embodiment on the systolic blood flow velocity (CRA-PSV) of the central retinal artery in the subject. The ophthalmic artery systolic blood flow velocity and the central retinal artery systolic blood flow velocity were measured using a Philips EPIQ Elite 9.0 ultrasound system.

[0092] The control group consisted of 21 participants, while the experimental group consisted of 22 participants. Figure 5 and Figure 6 Condition 1 for the control group was that after each subject had not used a smartphone and rested for 30 minutes, the systolic blood pressure and blood flow velocity of the ophthalmic artery and the central retinal artery were measured. Condition 2 was that after each subject used a smartphone to watch a video for 45 minutes, the systolic blood pressure and blood flow velocity of the ophthalmic artery and the central retinal artery were measured. Condition 3 was that after each subject continued to use a smartphone to watch a video for another 45 minutes, the systolic blood pressure and blood flow velocity of the ophthalmic artery and the central retinal artery were measured.

[0093] Figure 5 and Figure 6 Condition 1 for the experimental group was that after each subject had not used a smartphone and rested for 30 minutes, the systolic blood pressure and blood flow velocity of the ophthalmic artery and the central retinal artery were measured. Condition 2 was that after each subject watched a video on a smartphone for 45 minutes, the systolic blood pressure and blood flow velocity of the ophthalmic artery and the central retinal artery were measured. Condition 3 was that a radio wave generating device 1 was activated next to each subject to emit radio waves, and after each subject continued to watch a video on a smartphone for 45 minutes while the radio wave generating device 1 was activated, the systolic blood pressure and blood flow velocity of the ophthalmic artery and the central retinal artery were measured.

[0094] Depend on Figure 5It can be seen that, regardless of whether it was the control group or the experimental group, after watching videos on smartphones for 45 minutes (condition 2), the average ophthalmic artery systolic blood flow velocity decreased. In the control group, it decreased from 40.02380952 cm / sec to 34.60952381 cm / sec, and in the experimental group, it decreased from 39.07272727 cm / sec to 32.88181818 cm / sec. Subsequently, after the control group continued watching videos on smartphones for 45 minutes without using radio wave generating device 1 (condition 3), the average ophthalmic artery systolic blood flow velocity decreased to 32.74285714 cm / sec. In contrast, in the experimental group, after the subjects continued to watch videos on their smartphones for 45 minutes with the radio wave generating device 1 enabled (condition 3), the average ophthalmic artery systolic blood flow velocity increased to 40.77272727 (cm / sec), which was significantly higher than the average ophthalmic artery systolic blood flow velocity in condition 3 of the control group.

[0095] Depend on Figure 6 As can be seen, after watching videos on smartphones for 45 minutes (condition 2), the average systolic blood flow velocity of the central retinal artery decreased in both the control and experimental groups. In the control group, it decreased from 15.20952381 cm / sec to 12.27238095 cm / sec, and in the experimental group, it decreased from 13.68318182 cm / sec to 11.49363636 cm / sec. Subsequently, after the control group continued watching videos on smartphones for 45 minutes without using radio wave generating device 1 (condition 3), the average systolic blood flow velocity of the central retinal artery decreased to 10.67761905 cm / sec. In contrast, in the experimental group, after the subjects continued to watch videos on their smartphones for 45 minutes with the radio wave generating device 1 enabled (condition 3), the average central retinal artery systolic blood flow velocity increased to 14.71818182 (cm / sec), which was significantly higher than the average central retinal artery systolic blood flow velocity in the control group under condition 3.

[0096] As can be demonstrated from the above, the radio wave generating device 1 of this embodiment can indeed achieve the technical effect of promoting the blood flow velocity of the ophthalmic artery and the central retinal artery, and the increased blood flow velocity can delay eye fatigue.

[0097] Figure 7 and Figure 8 The diagram shows the first radio wave generating circuit 10a and the second radio wave generating circuit 20a of the second preferred embodiment of the present invention. Please refer to the diagram. Figure 7The first radio wave generating circuit 10a is substantially the same as the first radio wave generating circuit 10 of the first embodiment, except that it further includes a voltage level adjustment resistor R1.
