Description

Ultrasonic therapy system and its application Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to an ultrasonic treatment system and applications thereof. Background Art

[0002] Bats carry hundreds of giant viruses, including SARS, rabies, Ebola, and the novel coronavirus. However, their viral loads are relatively small, causing no symptoms, allowing them to coexist with the viruses. Even more surprising is bats' lifespan, which is significantly longer than similar-sized land mammals. The reason for bats' longevity—their ability to control inflammation—may offer new approaches to delaying aging.

[0003] What biological mechanisms make bats so unique that they can withstand a wide range of viruses and ensure their safety? The innate immune response senses cytoplasmic DNA and foreign RNA, responding with upregulation of interferon genes and production of other inflammatory cytokines such as TNF-α. Bats have undergone evolutionary adaptation, weakening their ability to sense cytoplasmic DNA through loss of the PYHIN gene and mutations in regulatory sites within STING.

[0004] In bats, expression of TNF-α and other inflammatory cytokines is reduced, while anti-inflammatory cytokines such as IL-10 are upregulated. Furthermore, activation of the NLRP3 inflammasome is suppressed in bats, leading to reduced production of IL-1β and IL-18 and enhanced RNA sensing. Furthermore, bats constitutively express TNF-α, enhance interferon gene expression, and possess enhanced autophagy. Taken together, these adaptive changes in bats enable them to tolerate viruses while suppressing inflammatory responses.

[0005] Alterations in immunity, leading to increased viral tolerance and reduced inflammation, underlie bats' longevity. Consequences of these changes include a reduction in inflammation-related diseases such as atherosclerosis, arthritis, neurodegeneration, and cancer. Thus, immune changes extend bat lifespan.

[0006] Research on bats reveals that they are one of the few mammals that use ultrasound to locate and prey. Others include naked mole-rats, which also coexist with numerous viruses and are known for their exceptional longevity. Therefore, the ability of bats and naked mole-rats to tolerate viruses, suppress inflammatory responses, and maintain longevity may be related to ultrasound.

[0087] The technical solution proposed by the present invention is to use ultrasound to stimulate the body's immune effect.

[0088] Ultrasound stimulation alters the body's immune system, triggering a series of immune responses, including increased interferon alpha expression, viral tolerance, and enhanced inflammation control. Based on bats' ability to transmit ultrasound and other related physiological characteristics, the inventors developed a specialized ultrasound therapy system.

[0089] The main parameters of the instrument are as follows:

[0090] Frequency: 20KHz~50KHz

[0091] Sound intensity: 0.1-1.6W / cm 2

[0092] The main evaluation indicators are as follows:

[0093] Interferon α, interferon β, interferon γ, CD4+ T cells, CD8+ T cells, TNF-α, IL-10, IL-1β, IL-15, IL-18

[0094] The main immune effects of this instrument can be used in the following aspects:

[0095] Anti-tumor

[0096] Antiviral

[0097] ●Prevent and improve inflammatory aging and prolong life

[0098] Treating autoimmune diseases

[0099] The inventors designed relevant animal experiments, using ultrasound to stimulate the body and verify its immune effect.

[0100] Experiment 1 designed a mouse liver tumor model. After more than a year of animal experiments and repeated optimization of technical parameters, the treatment group showed a 42% increase in interferon α, 35% increase in interferon β, 34% increase in interferon γ, a 72% increase in CD4+ T cells, and a 42% increase in IL-15 compared to the control group. Tumor cell growth was also suppressed. These experiments demonstrate that ultrasound stimulates the immune system, leading to the production of interferon and the increase in other beneficial immune factors and cells, thereby inhibiting tumor cells.

[0101] Experiment 2 designed a normal mouse model. After a series of animal experiments, the treatment group showed decreased TNF-α expression, increased anti-inflammatory cytokine IL-10, and decreased pro-inflammatory cytokines IL-1β and IL-18 compared to the control group. These changes may help control inflammation, delay aging, and treat autoimmune diseases.

[0102] The present invention is further illustrated by way of examples below, but the present invention is not limited to the scope of the examples. Experimental methods in the following examples where specific conditions are not specified were performed according to conventional methods and conditions, or selected according to the product specifications.

[0103] Example 1 Ultrasound therapy system

[0104] The ultrasonic treatment system of the present invention consists of a main unit and a treatment head.

[0105] The host part includes the following modules (the schematic diagram is shown in Figure 1):

[0106] Display module: It is mainly composed of an LCD screen. Human-computer interaction is achieved through the LCD screen. The parameters of ultrasound treatment can be set through the LCD screen, including frequency, sound intensity, time, duty cycle, etc., and the function of starting and stopping ultrasound treatment is provided.

[0107] Signal module: Generates ultrasonic fundamental frequency signal through DDS. The main control unit generates the electrical signal that drives the ultrasound based on parameters such as frequency, sound intensity, time, and duty cycle.

[0108] Power supply module: It is mainly responsible for converting AC power into DC voltage and providing constant DC voltage for various components.

[0109] Output module: uses MOS tube to amplify the output signal.

[0110] Matching module: matches the output electrical signal with the transducer to achieve consistency in voltage and current phase.

[0111] The treatment head is mainly generated by the piezoelectric vibrator, which is then output through the tool head. Both the piezoelectric vibrator and the tool head are designed to be half the wavelength. It includes the following modules:

[0112] Piezoelectric ceramics: Piezoelectric ceramic chips are components that convert electrical energy into mechanical energy and are the core components of ultrasonic therapy systems. This device's piezoelectric ceramics utilize four annular ceramic chips made of P42 material. P42 piezoelectric ceramics have high acoustic-to-electricity conversion efficiency and are suitable for immunotherapy. The number of these four annular piezoelectric ceramic chips is calculated based on the required acoustic power. Too few chips will produce too little power and fail to achieve the desired immunotherapy effect. Increasing the thickness of each chip increases the difficulty of manufacturing the piezoelectric chip, hindering immunotherapy. Piezoelectric chips have positive and negative poles, and the four chips need to be arranged alternately during installation, as shown in Figure 2.

[0113] The horn tool head can be designed in various shapes depending on the treatment needs. For example, a rectangular shape can be used for spleen treatment. Alternatively, a spherical design can be used to enhance transducer focus, as shown in Figure 3. The structure of a horn tool head with a rectangular output surface is shown in Figure 4; the structure of a spherical output surface is shown in Figure 5.

[0114] The horn tool head can be replaced to suit different output waveform requirements. For example, it can be designed into honeycomb, needle, ball head, etc. Note that the design of the horn needs to meet the theoretical requirements of half wavelength.

[0115] The output surface of a conventional horn tool head uses metal to directly contact the skin, which is not conducive to immunotherapy. This solution adds a thin layer of silicone rubber to the output surface, which prevents direct metal contact with the skin and also facilitates ultrasonic coupling, while preventing the thermal effects of ultrasound from being directly transmitted to the human skin.

[0116] The thick and thin transition of the horn tool head adopts a tangent circular surface transition method, which makes the transmission efficiency of ultrasound on the horn higher.

[0117] The horn tool head also has a flange for mounting the housing. The flange is located at the node point to minimize the impact on the transducer vibration. A schematic diagram is shown in Figure 6.

[0118] Front cover: Made of aluminum alloy.

[0119] Rear cover: Made of stainless steel.

[0120] Housing: Designed in cylindrical shape, convenient for handheld operation.

[0121] Set screws: These fasten the modules together. These screws must have a certain amount of prestress within a certain range. Double-stacked self-locking washers or disc washers are recommended; C-shaped washers are generally not recommended to prevent loosening during use. Use a torque wrench to ensure the torque is within the prestress range.

[0122] The treatment head of the present invention (structure shown in FIG7 ) generates ultrasonic waves after the piezoelectric ceramic is energized. Due to the high density of the stainless steel of the rear cover (about 7.9 g / cm 3 ), while the front cover aluminum alloy has a low density (about 2.8g / cm 3 ), resulting in a large displacement amplitude of the forward-directed ultrasonic output. The amplitude of the output ultrasonic waves is further increased by the front horn tool head, resulting in the treatment head of the present invention featuring high output efficiency and focused ultrasound. Furthermore, the tool head is designed to correspond in size to the treatment area, ensuring that the entire treatment head meets the requirements of immunotherapy.

[0123] Piezoelectric ceramics (structure shown in Figure 8) possess not only piezoelectricity but also dielectric and elastic properties. They are widely used in medical imaging, acoustic sensors, acoustic transducers, ultrasonic motors, and other applications. Piezoelectric ceramics are manufactured using the piezoelectric effect, a process in which mechanical stress causes the relative displacement of internal positive and negative charge centers within the material, leading to polarization. This results in bound charges of opposite sign forming on the surfaces of the material at both ends, giving them a sensitive characteristic.

[0124] The output surface of the horn tool head (structure shown in FIG9 ) is an elongated rectangle, which is designed to a corresponding size according to the shape of the treatment area so that the entire treatment head meets the needs of immunotherapy.

[0125] The ultrasonic waveform output by this device is a pulse-modulated sine wave. The schematic diagram of the sine wave is shown in Figure 10. In Figure 10, the horizontal axis is time and the vertical axis is the output amplitude. The frequency range of the output of this device is 20 to 50 kHz, and the output amplitude, that is, the ultrasonic sound intensity range is 0.1 to 1.6 W / cm 2 The schematic diagram of sinusoidal wave modulation is shown in Figure 11. The duration of transmission in the modulated waveform is the pulse width, the period from one transmission start point to the next is the cycle, and the pulse width divided by the cycle is the duty cycle. The pulse width of this device ranges from 10 to 1000 ms, and the cycle ranges from 20 to 2000 ms, corresponding to a duty cycle of 1 / 2 to 1 / 200. The total treatment time of this device ranges from 60 to 600 s. The ultrasound output of this device also undergoes a smooth transition algorithm, as shown in Figure 12. Each pulse output gradually increases in amplitude, reaching a stable pulse width after reaching the output amplitude. At the end of the pulse, the amplitude also gradually decreases. This output method is more comfortable and more tolerable for patients, while also making the device more stable and less prone to damage. It also better aligns with the characteristics of bat ultrasound output, making the device more realistic. Parameters such as the ultrasound output amplitude and duty cycle can be edited to generate treatment sequences based on treatment needs, making the device more intelligent and user-friendly. If new characteristics of bat ultrasound output are discovered later, the treatment sequence can be modified to continue the bionic design.

[0126] ●The positioning module is used to locate the treatment area and is an optional module. When precise positioning is required, a micro B-ultrasound probe can be used, generally a micro B-ultrasound probe is used. The B-ultrasound probe and the B-ultrasound host work together to detect the internal organs and tissues of the human body. By fixing the probe of the positioning module and the treatment head of the present invention together, the internal organs of the human body can be seen on the image of the positioning module, and the sound channel of the ultrasound treatment can also be determined according to the positional relationship. According to the treatment needs, the appropriate treatment sound channel and the appropriate treatment organ are selected for immunotherapy. The installation method of the positioning module and the treatment head is shown in Figure 13. The schematic diagram of the treatment ultrasound and treatment organs on the image of the positioning module is shown in Figure 14.

[0127] Example 2 Anti-tumor verification of ultrasound therapy system

[0128] The mouse liver tumor model was used to verify that low-frequency, low-intensity ultrasound acts on the body's immune system, stimulating the body's immune response, thereby inhibiting viruses and having anti-tumor effects. The experimental groups are shown in Table 1.

[0130] Note: All experimental mice were inoculated with tumors at the same time, and samples were taken for testing and treatment at the same time. 3 Or if the longest diameter of the tumor is greater than 15 mm, the experiment will be terminated.

Before the experiment, the mice were skin-prepared, and ultrasound was used to locate the treatment site (the spleen) on their skin. The mice were anesthetized and then treated.
