Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and mainly relates to a steady-state output frequency millimeter wave therapy device. Background Technology

[0002] Millimeter wave therapy devices, as medical devices that utilize millimeter wave energy for disease treatment and rehabilitation, have been widely used in various clinical fields such as orthopedics, rehabilitation medicine, and dermatology due to their significant efficacy in soft tissue injury repair, inflammation reduction, and pain relief. Millimeter wave therapy devices emit millimeter waves through oscillating elements, which are then irradiated onto the patient via a radiator. The core of its therapeutic effect lies in the precision of the output energy frequency. Only when the device operates at a specific optimal frequency can the millimeter waves produce the best resonance effect with human tissue cells, thereby maximizing the stimulation of the body's own repair mechanisms and achieving ideal therapeutic results.

[0003] However, in practical applications, the output frequency stability of millimeter-wave therapy devices faces multiple challenges. First, the diverse usage scenarios significantly impact the device's frequency: in different clinical environments, such as operating rooms, rehabilitation wards, and home care, the intensity of electromagnetic interference and the stability of the power supply voltage vary. These external factors directly cause fluctuations in the operating state of the oscillation circuit, leading to frequency deviation. Second, changes in ambient temperature and humidity are crucial factors that cannot be ignored: the core oscillation components of millimeter-wave therapy devices are extremely sensitive to temperature and humidity. Increased or decreased temperature alters the physical parameters of the components, while changes in humidity can affect the insulation performance and heat dissipation efficiency. Both factors combined cause the frequency to deviate from the preset value. Furthermore, the aging phenomenon after long-term use further exacerbates the frequency instability problem: with increasing usage time, the parameters of components such as capacitors and inductors in the circuit drift, the contact resistance of connectors gradually increases, and the efficiency of the heat dissipation system decreases. These cumulative aging effects cause the frequency stability of the device to continuously deteriorate.

[0004] The aforementioned frequency deviation directly impacts the therapeutic efficacy and safety of millimeter-wave therapy devices. When the output frequency deviates from the optimal operating frequency, not only will the expected therapeutic effect fail to be achieved, but it may even cause unnecessary stimulation or damage to human tissues due to abnormal energy distribution. Currently, existing technologies for adjusting the frequency of millimeter-wave therapy devices mostly employ periodic calibration, meaning that professionals manually adjust the device after a period of use. This method is not only cumbersome and costly to maintain, but it also cannot respond in real-time to dynamically changing usage environments and device conditions, making it difficult to ensure that the frequency remains at the optimal operating point during treatment. This severely restricts the reliability and accuracy of millimeter-wave therapy devices in clinical applications. Therefore, developing a technical solution that can monitor and automatically adjust the output frequency to the optimal operating frequency in real time has become an urgent need to improve the performance of millimeter-wave therapy devices. Utility Model Content

[0005] This invention provides a steady-state output frequency millimeter wave therapy device to solve the problem that the working frequency of existing millimeter wave therapy devices may deviate, resulting in the inability to accurately output the optimal working frequency.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A steady-state output frequency millimeter wave therapy device includes a device body, the device body including a shell with an inner cavity, and further including a coupling detector, a frequency divider, a counter, a drive module and a microcontroller arranged in the inner cavity of the shell;

[0008] The coupling detector is arranged around the radiator to detect the millimeter-wave frequency radiated at the radiator location. The frequency divider is used to divide the millimeter-wave frequency to reach the detection range of the counter. The counter is used to count the divided millimeter-wave frequency. The microcontroller is used to process the counting signal to solve for the real-time operating millimeter-wave frequency detected by the coupling detector. The drive module is used to receive the control signal from the microcontroller and convert it into a drive signal to drive the oscillation element.

[0009] It has the following beneficial effects: The working frequency of the millimeter wave therapy device is radiated outward by the radiator, and the coupling detector is arranged around the radiator, which can directly detect the real-time millimeter wave frequency at the location of the radiator and capture the original signal of the current working frequency from the source. The drive module is directly associated with the oscillation element. When the microcontroller determines that there is a frequency deviation, it will output the corresponding control signal. The drive module converts the signal into a drive signal that the oscillation element can respond to, and finally makes the output frequency of the oscillation element approach the optimal frequency until the deviation is eliminated.

Users can simply unlock the door panel to open it when taking or putting in items, and close and lock it after use. It is simple to operate and requires no additional tools.

[0014] Furthermore, the housing is provided with heat dissipation holes that communicate with the inner cavity, and a cooling fan located in the inner cavity is provided at the heat dissipation holes.

[0015] It has the following beneficial effects: The cooling fan maintains a low temperature environment inside the cavity by expelling hot air through the heat dissipation holes, ensuring that each component works stably within the rated temperature range and avoiding inaccurate monitoring data due to high temperature.

[0016] Furthermore, the housing is provided with a power socket and a power switch, the power switch being used to control the on / off state of the power socket.

[0017] It has the following beneficial effects: the device can be powered by connecting an external power source to a power socket on the casing via a wire, and the power switch can control whether the external power source can power the device.

[0018] Furthermore, a display is detachably mounted on the outside of the housing.

[0019] It has the following advantages: The detachable design allows only the monitor to be removed for repair or replacement without disassembling the main body of the device, thus avoiding long-term downtime of the entire device due to monitor repair.

[0020] Furthermore, a movable base is provided at the bottom of the main body of the device.

[0021] It has the following benefits: the mobile base enables easy movement of the device without the need for multiple people to carry it, allowing the device to quickly respond to treatment needs in different scenarios.

[0022] Furthermore, the movable base includes a mounting base and rollers mounted on the mounting base, and the main body of the device is mounted on the mounting base. Attached Figure Description

[0030] like Figures 1-5 As shown, a steady-state output frequency millimeter-wave therapy device includes a main body, which includes a housing 9 with an inner cavity 17. The device also includes an oscillating element 1, a radiator 2, a coupling detector 3, a frequency divider 4, a counter 5, a microcontroller 6, and a drive module 7 arranged within the inner cavity 17 of the housing 9. The oscillating element 1 emits millimeter waves, which are then used to treat the patient via the radiator 2. In this embodiment, there are two radiators 2. The coupling detector 3, frequency divider 4, counter 5, microcontroller 6, and drive module 7 are electrically connected in sequence, and the drive module 7 is electrically connected to the oscillating element 1.

[0031] The coupling detector 3 is arranged around the radiator 2 to detect the millimeter wave frequency radiated at the location of the radiator 2. The frequency divider 4 is used to divide the millimeter wave frequency to reach the detection range of the counter 5. The counter 5 is used to count the divided millimeter wave frequency. The microcontroller 6 is used to process the counting signal to solve for the real-time working millimeter wave frequency detected by the coupling detector 3. The drive module 7 is used to receive the control signal of the microcontroller 6 and convert it into a drive signal to drive the oscillation element 1 to work.

[0032] The coupling detector 3 is positioned directly around the radiator 2, enabling it to acquire the actual millimeter-wave frequency output by the radiator 2 in real time. The frequency deviation of the millimeter-wave therapy device is the deviation between the actual output frequency and the preset optimal frequency. By detecting the real-time radiation frequency of the radiator 2 at close range, the coupling detector 3 can obtain the true operating frequency data from the source, providing the original basis for subsequent deviation judgment.

[0033] In this embodiment, the detection capability of counter 5 has an upper limit. Frequency divider 4 converts the high-frequency millimeter-wave signal into a low-frequency signal that counter 5 can recognize through fixed-ratio frequency division, ensuring the validity of subsequent counting. Counter 5 then converts the frequency-divided low-frequency signal into a digital counting result. This allows microcontroller 6 to deduce the actual millimeter-wave frequency from the counting result, providing a calculable data basis for quantitative analysis of the offset.

[0034] The drive module 7 is directly associated with the oscillating element 1. When the microcontroller 6 determines that there is a frequency offset, it will output a corresponding control signal. The drive module 7 converts the signal into a drive signal that the oscillating element 1 can respond to, so that the output frequency of the oscillating element 1 moves closer to the optimal frequency until the deviation is eliminated.

[0035] In this embodiment, the driving module 7 is a driving module that changes the oscillation frequency or amplitude by adjusting the input voltage. The digital control signal output by the microcontroller 6 is converted from digital to analog to obtain an analog voltage. The driving module 7 amplifies, filters, or regulates this voltage and outputs a stable driving voltage to the oscillation element 1 to realize frequency modulation or start / stop control.

[0036] In other embodiments, the driving module 7 is a driving module that changes the oscillation frequency or amplitude by adjusting the input current. The microcontroller 6 sets the target current value through a control signal, and the driving module 7 adjusts the output current in real time through a current feedback circuit to ensure that the oscillating element 1 operates under constant current conditions and avoids frequency deviation due to current fluctuations.

[0037] In other embodiments, the driving module 7 is a driving module 7 that requires periodic pulse signal triggering to operate. The pulse control signal output by the microcontroller 6 is amplified by the driving module 7 to generate a high voltage or high current pulse, which triggers the oscillation element 1 to oscillate within a specific time period, thereby realizing pulsed millimeter wave output.

[0038] In this embodiment, the shell 9 can be made of plastic or metal. The metal can be stainless steel or aluminum alloy.

[0039] In this embodiment, as Figure 5 As shown, the housing 9 contains a storage cavity 18, which can hold personal belongings or treatment items. When receiving millimeter-wave therapy, patients can temporarily place personal items such as mobile phones, keys, wallets, and glasses in the storage cavity 18. The storage cavity 18 provides built-in storage space, eliminating the need for patients to search for additional storage areas. Furthermore, compared to simply leaving items in a corner, the built-in storage cavity 18 reduces the risk of items being lost, accidentally bumped, or dropped.

[0040] Meanwhile, millimeter wave therapy involves auxiliary items, and the storage cavity 18 can be specifically used to store these items, allowing medical staff or users to quickly access them before and after treatment without having to frequently travel between the treatment area and the storage room, thus shortening preparation time.

[0041] In this embodiment, as Figures 2-5 As shown, the housing 9 has a door panel 11. One side of the door panel 11 is hinged to the housing 9, and the other side is fixed to the housing 9 by a locking mechanism. By locking the door panel 11 to the housing 9, the storage cavity 18 forms a sealed space. With one side hinged and the other fixed by the locking mechanism, the user only needs to unlock the door panel 11 to open it when taking or placing items, and close and lock it after use. The operation is simple and requires no additional tools. After the door panel 11 is fixed by the locking mechanism, the storage cavity 18 forms a physically enclosed space, preventing personal belongings or treatment items from accidentally falling out during treatment if the equipment moves, tilts, or is accidentally touched by the user.

[0042] In this embodiment, the locking mechanism can be a snap-fit, magnetic attraction, key lock, etc.

[0043] In this embodiment, as Figures 2-4 As shown, the housing 9 has heat dissipation holes 10 communicating with the inner cavity 17, and a cooling fan 19 located in the inner cavity 17 is installed at the heat dissipation holes 10. The cooling fan 19 rotates, blowing hot air from the inner cavity 17 to the outside of the housing 9, thereby reducing the temperature inside the inner cavity 17 and protecting the various electronic components within it. The coupling detector 3, frequency divider 4, counter 5, microcontroller 6, and other components inside the inner cavity 17 are all precision electronic components, and their performance is sensitive to temperature. The cooling fan 19 maintains a low-temperature environment in the inner cavity 17 by expelling hot air through the heat dissipation holes 10, ensuring that each component operates stably within its rated temperature range and preventing inaccurate monitoring data due to high temperatures.

[0044] Operating electronic components in high-temperature environments for extended periods accelerates the oxidation of internal materials and degrades their insulation properties, leading to shorter component lifespans and increased failure rates. The cooling fan 19 continuously lowers the temperature, slowing down the aging process, reducing hardware failures caused by high temperatures, thereby extending the overall lifespan of the equipment and lowering maintenance and replacement costs.

[0045] In this embodiment, as Figure 4 , Figure 5 As shown, the housing 9 is equipped with a power socket 16 and a power switch 15. The power switch 15 is used to control the on / off state of the power socket 16. In use, the device is powered by connecting an external power source to the power socket 16 on the housing 9 via a power cord. The power switch 15 controls whether the external power source can supply power to the device.

[0046] In this embodiment, as Figures 2-5As shown, a display 8 is detachably mounted on the housing 9. The display 8 can be used to display millimeter-wave frequencies. When the display 8 needs repair, it can be removed and replaced separately. Additionally, to prevent damage to the display 8 during transport, it can be removed from the device. This detachable design allows for repair or replacement of only the display 8 without disassembling the main unit, avoiding prolonged downtime of the entire device due to display 8 repair. A new display 8 can be directly installed.

[0047] The display screen of monitor 8 is a fragile component and is easily damaged by vibration and impact during equipment handling. The detachable design allows monitor 8 to be removed separately before transport, reducing the probability of monitor 8 being subjected to external impacts and protecting its integrity by transporting the main body of the equipment and monitor 8 separately. Furthermore, when the equipment is not in use for extended periods or is being stored, monitor 8 can be disassembled and stored separately in a moisture-proof and dust-proof environment, preventing poor storage conditions of the casing 9 from affecting monitor 8's performance and extending its lifespan.

[0048] In this embodiment, as Figures 2-4 As shown, the bottom of the main body of the device is equipped with a movable base 12, which enables the main body of the device to be moved, facilitating the transfer of the device to multiple treatment locations. The movable base 12 allows for easy movement of the device without the need for multiple people to carry it, allowing the device to quickly respond to the treatment needs of different scenarios.

[0049] Millimeter-wave therapy devices are quite heavy. Manual handling requires multiple people and could lead to damage or injury due to improper force. The movable base 12 replaces sliding friction with rolling friction, significantly reducing movement resistance. A single person can easily push the device, saving labor costs and reducing operational risks.

[0050] In this embodiment, the movable base 12 is equipped with a braking mechanism, which can quickly fix the device after it is moved to the target position, preventing the device from sliding during use and ensuring stability during treatment.

[0051] In this embodiment, the mobile base 12 includes a mounting base 13 and rollers 14 mounted on the mounting base 13. The rollers 14 are located on the lower side of the mounting base 13 and are used to contact the ground. The main body of the equipment is mounted on the upper side of the mounting base 13. The rollers 14 are made of non-slip and wear-resistant material, which can move smoothly on various surfaces such as ceramic tiles, wooden floors, and cement floors, reducing bumps or noise.

[0052] The working process of this utility model is as follows:

[0053] Inside the main body of the device, a drive module 7 and an oscillating element 1 are placed. During operation, the energy output from the oscillating element 1 is transmitted to the radiator 2 via a built-in coaxial cable, and then radiated outwards. At this time, a coupling detector 3 placed near the radiator 2 couples the energy and transmits it backwards to a frequency divider 4. The frequency divider 4 divides the millimeter wave to reach the signal processing range of a counter 5. The counter 5 then processes the signal and transmits it to a microcontroller 6. The microcontroller 6 processes the data to calculate the current radiation frequency of the radiator 2 and displays it on a display 8. When the microcontroller 6 detects a frequency deviation from the optimal operating frequency, it sends a control signal to the drive module 7, causing the drive module 7 to adjust the operating state of the oscillating element 1 and readjust the output frequency to the optimal operating frequency, achieving a steady-state effect.
