Description

Technical Field

[0001] The present invention relates to the technical field of therapeutic apparatus, and more specifically, to a method and system for adjusting the transmission power of an ultrashort wave therapeutic apparatus. Background Art

[0002] Ultrashort wave therapy device is a traditional therapeutic instrument. It uses electron tube oscillation to generate ultrashort wave high-frequency electric field for treatment. Usually, the radio frequency current with a wavelength of 1 to 10m and a frequency of 30 to 300MHz is called ultrashort wave current, and it is called ultrashort wave therapy when used in clinical practice. Most devices output energy through capacitor electrodes. The affected part is placed between the electrodes. Under the action of the high-frequency electric field, the molecules and ions in the lesion site vibrate in their parallel positions and rub against each other to produce a thermal effect. This thermal effect heats the surface and deep tissues of the affected part evenly, which can enhance vascular permeability, improve microcirculation, regulate endocrine, strengthen the metabolism of the tissue body, and reduce the excitability of sensory nerves, thereby achieving the therapeutic purpose of inhibiting bacteria, reducing inflammation, relieving pain, relieving spasm, promoting blood circulation and repair, and enhancing the body's immunity. At present, in the process of using the ultrashort wave therapy device, the user needs to sit on the seat of the ultrashort wave therapy device. After the solid-state source on the ultrashort wave therapy device outputs the signal, it passes through the directional coupler, and finally the radio wave emitted by the moxibustion stool antenna will be received by the user, so as to treat the user.

[0003] In the related technology, for example, the Chinese patent application document with publication number CN221286640U discloses an ultrashort wave therapy device that can display the distance through a display panel. According to the displayed distance, medical staff can continue to adjust the position of the treatment host until the displayed distance reaches the optimal treatment position, so that medical staff can clearly know the exact position of the electrode head and the treatment position, and then accurately position the electrode head.

[0004] When using an ultrashort wave therapy device to treat a user, the user's body will reflect a portion of the radio waves that are not received after receiving the radio waves. During the treatment process, the reflection will become larger due to the material and thickness of the user's clothes, resulting in more radio waves not being absorbed by the user, thus causing poor treatment effects on the user.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0018] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] In one embodiment, a user sitting posture detection device of an ultrashort wave therapeutic apparatus comprises a moxibustion stool body, a directional coupler, a moxibustion stool antenna and a single-chip microcomputer, and a solid-state source is provided on the top of the moxibustion stool body. In a short-wave therapeutic apparatus, a solid-state source refers to a core component that uses solid-state electronic devices (such as high-power semiconductors) as energy conversion and amplification. These solid-state devices can efficiently convert electrical energy into high-frequency electromagnetic energy and radiate it into human tissue through a specific antenna, thereby producing a therapeutic effect. A solid-state source, wherein the solid-state source is used to emit electromagnetic waves; one end of the solid-state source is connected to a directional coupler, and one end of the directional coupler is connected to a moxibustion stool antenna; the input port of the directional coupler is used to receive the electromagnetic waves output by the solid-state source, and the output port of the directional coupler transmits the electromagnetic waves to the moxibustion stool antenna, and the moxibustion stool antenna is used to emit the electromagnetic waves as therapeutic radio waves; a single-chip microcomputer is also connected to the directional coupler, and the single-chip microcomputer is connected to the coupling port and the isolation port of the directional coupler through an analog-to-digital converter, and the single-chip microcomputer is used to collect the forward power and directional power of the directional coupler. The performance of the solid-state source directly determines the therapeutic effect and therapeutic depth of the short-wave therapeutic apparatus. And by adjusting the working parameters of the solid-state source (such as voltage, current, etc.), the frequency, power and other parameters of the output energy can be easily controlled to meet different treatment needs.

[0020] In one embodiment, during the use of the ultrashort wave therapeutic device, the user needs to sit on the ultrashort wave therapeutic device, and then start the ultrashort wave therapeutic device. The ultrashort wave therapeutic device will transmit radio waves to the user to treat the user. After receiving the radio waves, the user's body will reflect a part of the radio waves that are not received. However, during the treatment process, due to the influence of the material and thickness of the clothes worn by the user, the emission will become larger, resulting in more radio waves that are not absorbed by the user, thus resulting in poor treatment effect on the user. Therefore, this solution can adjust the transmission power of the ultrashort wave therapeutic device to achieve a normal treatment level. The specific steps are as follows.

[0021] Example 1 S101: Obtain the transmission power and reflection voltage of the ultrashort wave therapy device.

[0022] In one embodiment, the transmission power of the ultrashort wave therapy device is obtained, and the transmission power can be adjusted directly on the short wave therapy device manually, for example, the transmission power of the ultrashort wave therapy device is adjusted to P1, P2 or P3, etc. The reflected voltage is obtained: the reflected voltage of the short wave therapy device when it is working can be obtained by the ADC detection method.

[0023] In one embodiment, the basic principle of the analog-to-digital converter (ADC detection) is to sample the input analog signal at a specified time interval and compare it with a series of standard digital signals. The digital signals converge one by one until the two signals are equal. Then the binary number representing the signal is displayed. This process usually includes four steps: sampling, holding, quantization and encoding. Sampling and holding may be combined, and quantization and encoding are often implemented simultaneously during the conversion process.

[0024] S102: Calculate user received power.

[0025] In one embodiment, after receiving the reflected voltage of the ultrashort wave therapy device, the load of the ultrashort wave therapy device in working state is collected, and finally the reflected power is calculated according to Ohm's law. Finally, the user received power is obtained according to the difference between the transmitted power and the reflected power.

[0026] For example, the transmitting power of the ultrashort wave therapy device is set to P2, the reflected voltage of the ultrashort wave therapy device is detected by ADC as U1, the load of the ultrashort wave therapy device in the working state is R1, and then according to Ohm's law , calculate the reflected power P4, and then calculate the difference between the transmitted power P2 and the reflected power P4 to obtain the user received power.

[0027] S103: Calculate target transmission power.

[0028] In one embodiment, the actual reflected voltage of the ultrashort wave therapy device is obtained, the actual reflected power is calculated using Ohm's law, and the ratio of the current transmission power to the actual reflected power is used as the reflection ratio; based on the ratio of the user's received power to the reflection ratio, the next target transmission power is obtained.

[0029] In one embodiment, the actual reflected power is calculated. For example, the actual reflected voltage of the ultrashort wave therapy device is detected by ADC as U2, and the load of the ultrashort wave therapy device in the working state is R2, and then according to Ohm's law , calculate the actual reflected power .

[0030] In one embodiment, the reflectance is calculated using the following formula: In the formula, represents the reflectance, Indicates the current transmission power. Indicates the actual reflected power of this time.

[0031] In one embodiment, after the reflection ratio is obtained, the target transmission power for the next time is obtained based on the ratio of the user's received power to the reflection ratio. Exemplarily, if the user's received power is P6 and the reflection ratio is K, the target transmission power is P6 / K. After the target transmission power is obtained, the transmission power of the ultrashort wave therapy device is adjusted to P6 / K. At this time, the user can receive the radio waves during normal treatment.

[0032] Example 2 In one embodiment, it is considered that the user cannot maintain a completely unchanged sitting posture on the ultrashort wave therapy device, and the sitting posture may change slightly. Since the user is equivalent to a medium when using the ultrashort wave therapy device, the change in posture is actually equivalent to the change in capacitance, which will result in a slight change in the detected reflected voltage U, thereby causing the calculated target transmission power to be inaccurate. Therefore, the target transmission power needs to be corrected again to obtain a more accurate transmission power of the ultrashort wave therapy device.

[0033] In one embodiment, to detect whether the posture of the user on the ultrashort wave therapy device has changed, a pressure sensor may be used to collect the pressure value of the user for judgment. The reason is that when the user uses the same sitting posture to sit on the ultrashort wave therapy device, since the sitting posture has not changed, the pressure value measured by the pressure sensor on the ultrashort wave therapy device will not change much. At this time, it is judged that the sitting posture of the user on the ultrashort wave therapy device has not changed. On the contrary, when the pressure value measured by the pressure sensor on the ultrashort wave therapy device changes greatly, it means that the user's sitting posture on the ultrashort wave therapy device has changed greatly. At this time, it is judged that the user's sitting posture on the ultrashort wave therapy device has changed significantly.

[0034] S201: Collect the user's pressure value.

[0035] Therefore, it is possible to determine whether the target transmission power needs to be corrected according to the change in the pressure value. Specifically, the pressure value of the current user is collected once at every preset time interval, and the pressure value is detected by the pressure sensor on the ultrashort wave therapy device. In this embodiment, the preset time interval is 0.5 seconds. In other embodiments, the preset time interval can be 0.7 seconds or 1 second, etc., which can be adjusted according to the specific implementation situation; S202: Determine whether the target transmission power needs to be corrected.

[0036] In one embodiment, in response to the user's pressure value being less than a preset threshold, the target transmit power is corrected using the historical target transmit power to obtain the next final transmit power. In this embodiment, the empirical value of the preset threshold is 10N, and in other embodiments, the empirical value of the preset threshold may be 15N or 20N, etc., which may be adjusted according to specific implementation conditions.

[0037] S203: Correct the target transmit power to obtain a final transmit power.

[0038] In one embodiment, the target transmit power is corrected using the historical target transmit power to obtain the final transmit power, wherein the correction formula is: ; In the formula, In the formula, Indicates The final transmission power is Indicates the number of times the user pressure value collected in the historical data is continuously less than the preset threshold. Indicates The target transmission power.

[0039] Exemplarily, the pressure value of the current user is collected every 5 seconds. If 4 pressure values ​​were collected before this pressure value is collected, the first pressure value is N1, the second pressure value is N2, the third pressure value is N3, and the fourth pressure value is N4, if the absolute value of the difference between the pressure value N2 and the pressure value N1 is less than the preset threshold, it means that the second pressure value change is less than the preset threshold. Similarly, if the absolute value of the difference between the pressure value N3 and the pressure value N2, and the absolute value of the difference between the pressure value N4 and the pressure value N3 are both less than the preset threshold, the final transmission power of the fifth time is calculated, and the final transmission power is equal to (N1+ N2+ N3+ N4) / 4. Then adjust the transmission power of the ultrashort wave therapy device to the final transmission power, and use the final transmission power to treat the user.

[0040] In other words, the transmission power of the next ultrashort wave therapy device can be predicted based on the pressure value before this time, without having to calculate the target transmission power of the ultrashort wave therapy device in each time period one by one, which reduces the amount of calculation and improves work efficiency.

[0041] It should be noted that if the pressure value of the user measured at any time is greater than the preset threshold, it means that the user's sitting posture has changed significantly and the transmission power needs to be changed significantly. Therefore, it is necessary to recalculate the target transmission power of the ultrashort wave therapy device according to the method for calculating the target transmission power in Example 1.

[0042] Exemplarily, the pressure value of the current user is collected once every 5 seconds. If 5 pressure values ​​are collected before the current pressure value is collected, the first pressure value is Y1, the second pressure value is Y2, the third pressure value is Y3, the fourth pressure value is Y4, and the fifth pressure value is Y5. If the difference between the pressure value Y2 and the pressure value Y1 is greater than the preset threshold, the transmission power of the ultrashort wave therapy device should be recalculated according to the method for calculating the target transmission power in Example 1. If the difference between the pressure value Y3 and the transmission power recalculated last time is less than the preset threshold, the transmission power of the ultrashort wave therapy device for the fourth time can be calculated based on the transmission power corresponding to the pressure values ​​Y2 and Y3.

[0043] Through the above steps, the transmission power of the ultrashort wave therapy device can be adjusted according to the reflection power of the ultrashort wave therapy device and the receiving power of the user, which solves the problem that the material and thickness of the user's clothes will increase the transmission, resulting in more radio waves not being absorbed by the user, thereby achieving a normal treatment level for the user and improving the treatment effect.

[0044] The present invention also provides a method for adjusting the transmission power of an ultrashort wave therapeutic device.

[0045] The system also includes other components familiar to those skilled in the art, such as a communication bus and a communication interface, whose configuration and functions are known in the art and thus will not be described in detail here.
