Description

Warmer and method of implementing the same

[0001] The present invention relates to a heating device and a method for operating the same, and more specifically, to a heating device and a method for operating the same that uses microwaves to generate heat of a specific temperature inside the human body so as to selectively eliminate bacteria and viruses only at the site of infection.

[0002] Modern medicine has advanced treatments for various diseases through technological progress. However, there are still many limitations in the fundamental treatment of intractable diseases caused by bacterial and viral infections, particularly diseases such as cancer. Representative technologies generally used to treat cancer and viral diseases include radiation therapy, proton therapy, and heavy ion therapy. While these treatments are effective to some extent, each carries distinct limitations and side effects.

[0003] Radiation therapy is a technique that destroys cancerous tissue by irradiating cancer cells with radiation energy generated by accelerating electrons. Although this method is relatively widely used, it has the following problems.

[0004] First, radiation affects not only cancer cells but also surrounding normal tissues. This can cause serious side effects on organs and tissues and significantly reduce the patient's quality of life after treatment.

[0005] Second, while radiation is effective in areas close to surface tissues, it is difficult to access tumors located deep inside the body.

[0006] Third, there is a high possibility of the disease recurring because cancer cells are not completely eliminated.

[0007] Furthermore, proton therapy is a method of irradiating cancer cells with an energy beam generated by accelerating protons (hydrogen nuclei) to 60% of the speed of light. It utilizes the unique characteristic of protons, the 'Bragg Peak,' to deliver high concentrations of radiation exclusively to cancer tissue. This method is evaluated as having fewer side effects and higher therapeutic efficacy compared to radiation therapy. However, proton therapy also has the following problems.

[0008] First, proton therapy equipment is very expensive, and the infrastructure required for its installation and operation is limited. Therefore, the potential for treatment is limited worldwide.

[0009] Heavy ion therapy is a technology that accelerates carbon ions, which are heavier than protons, to 70% of the speed of light and irradiates them onto cancer cells. It is known to deliver more powerful energy compared to radiation and proton therapy and has excellent cancer cell killing capabilities. However, heavy ion therapy also has the following disadvantages.

[0010] First, patients with metastasis are excluded from treatment, and it is used restrictively only for early-stage cancer patients.

[0011] Second, heavy ion therapy equipment is more expensive than proton therapy, and side effects may occur in some patients.

[0012] The existing treatments mentioned above primarily work by utilizing radiation to physically destroy cancer cells or inhibit their growth. However, this approach fails to address the following fundamental problems.

[0013] First, radiation, proton, and heavy ion therapies all have limitations in penetrating deep into the body, so treatment is limited to specific areas within the body.

[0014] Second, it fails to eliminate bacteria and viruses identified as major causes of cancer, and therefore, the risk of recurrence remains.

[0015] Third, radiation therapy and proton therapy have a negative long-term impact on patients' lives due to damage to normal tissues and serious side effects.

[0016] The goal of modern medicine is to simultaneously enhance the safety and efficacy of patient treatment. To achieve this, treatment technologies capable of selectively eliminating cancer cells, bacteria, and viruses without damaging normal tissues are required.

[0017]

[0018] The present invention aims to provide a heating device and a method for implementing the same, which uses microwaves to generate heat of a specific temperature inside the human body to selectively eliminate bacteria and viruses only at the site of infection.

[0019] In addition, the present invention aims to provide a warmer and a method for operating the same that eliminate normal tissue damage and side effects occurring in conventional radiation, proton, and heavy ion therapies, and enable safe treatment for patients.

[0020] In addition, the present invention aims to provide a warming device and a method for implementing the same, which utilizes a principle of inducing pain in the affected area during the treatment process to rapidly diagnose the infected area and enable early treatment of the disease.

[0021] In addition, the present invention aims to provide a heating device having versatility that can be utilized not only for bacterial and viral infectious diseases but also for intractable diseases such as vascular diseases (e.g., angina pectoris) and a method for implementing the same.

[0022] In addition, the present invention aims to provide a warmer and a method for implementing the same, which can be established as a medical device that can be safely used over the long term by completely blocking harmful waves generated during the treatment process.

[0023] In addition, the present invention aims to provide a warming device and a method for implementing the same, which is effective in treating vascular diseases such as angina pectoris through the function of opening blood vessels blocked by high heat, and which can accelerate the recovery of patients by improving blood flow and removing inflammation.

Furthermore, it will be readily apparent that the objects and advantages of the present invention can be realized by the means and combinations thereof set forth in the claims.

[0026] In one embodiment, the heater further includes an output coupler for controlling the strength of an electromagnetic wave signal generated in the resonant cavity, a filter circuit for removing unnecessary frequencies among the electromagnetic wave signals generated in the resonant cavity, and a vacuum chamber for maintaining an internal space including a cathode and an anode in a vacuum state.

[0027] In addition, a method for operating a heating device to achieve this purpose includes the steps of: stimulating the resonant cavity of the anode by means of a magnet while electrons emitted from the cathode rotate spirally; a step in which the resonant cavity amplifies electromagnetic waves to a specific frequency, after which a filter circuit removes unnecessary frequencies from the electromagnetic wave signal generated in the resonant cavity; a step of adjusting the strength of the electromagnetic wave signal through an output coupler when the electromagnetic wave signal is output by the filter circuit; and a step of emitting the electromagnetic waves generated in the resonant cavity to the outside through an output antenna.

[0028] According to the present invention as described above, there is an advantage in that heat of a specific temperature is generated inside the human body using microwaves, thereby selectively eliminating bacteria and viruses only at the site of infection.

[0039] The aforementioned objectives, signatures, and advantages are described in detail below with reference to the attached drawings, thereby enabling those skilled in the art to easily implement the technical concept of the present invention. In describing the present invention, detailed descriptions of known technologies related to the present invention are omitted if it is determined that such descriptions would unnecessarily obscure the essence of the invention. Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings. In the drawings, the same reference numerals are used to indicate the same or similar components.

[0040] FIG. 1 is a block diagram illustrating the internal structure of a heater according to an embodiment of the present invention. FIG. 2a and FIG. 2b are drawings illustrating a heater according to an embodiment of the present invention.

[0041] Referring to FIGS. 1, 2a, and 2b, the heating device (100) emits microwaves of a specific wavelength (1 mm to 1600 mm) to the affected area and penetrates into the human body.

[0042] In one embodiment, the heating device (100) may be designed primarily based on a medical magnetron. A magnetron is a device that generates microwaves and transmits heat into the human body by emitting electromagnetic waves.

[0043] The heating device (100) includes a negative electrode (105), a positive electrode (110), a resonant cavity (115), a magnet (120), an output antenna (125), a cooling unit (130), an output coupler (135), an insulator (140), a filter circuit (145), and a vacuum chamber (150).

[0044] The cathode (105) is a part that emits electrons and is usually made of a tungsten filament. The cathode (105) is located at the center of the magnetron and serves to emit electrons. When power is supplied to the cathode (105), the filament is heated and emits thermionic electrons. These electrons are accelerated by magnetic and electric fields inside the magnetron.

[0045] When power is supplied to the cathode (105), thermionic electrons are emitted from the heated cathode. In this cathode (105), the electric field of the positive electrode attracts electrons, and due to the magnet, the electrons do not go directly to the positive electrode but move in a spiral trajectory. In this process, the electrons stimulate the resonant cavity to generate electromagnetic waves of a specific frequency.

[0046] In one embodiment, the cathode (105) emits electrons based on [Equation 1]. [Equation 1] represents the amount of electrons emitted from the cathode due to a voltage difference, and electrons begin to be emitted when the voltage exceeds a threshold voltage.

[0049] I e : Discharged current (A),

[0050] β: emission coefficient,

[0051] V e: Voltage between the negative and positive electrodes (V),

[0052] V th : The threshold voltage that initiates electron emission

[0053] The anode (110) attracts electrons emitted from the cathode and generates microwaves of a specific frequency through resonant cavities. This anode (110) is designed as a circular metal ring surrounding the cathode and includes multiple resonant cavities. The resonant cavities are spaces designed to allow electrons to vibrate at a specific frequency. At this time, the frequency and efficiency of the microwaves are determined by the size and arrangement of each cavity.

[0054] The energy conversion of electrons at the anode (110) is as [Equation 2], which is related to the emission of electromagnetic waves. In particular, the Laplace equation or the electromagnetic wave equation regarding the motion and emission of electrons can be used. For example, the wave equation of the electromagnetic wave is as [Equation 2].

[0057] E: Electric field,

[0058] μ: Magnetism,

[0059] ∈: permittivity,

[0060] t: time,

[0061] The resonant cavity (115) serves to generate and amplify electromagnetic waves as electrons move. The resonant cavity (115) consists of small metal chambers arranged inside the anode, each chamber resonating at a specific frequency. These resonant cavities (115) amplify electromagnetic waves by stimulating the electromagnetic field of the resonant cavity as electrons rotate within the magnetic field, thereby generating microwaves of a desired frequency.

[0062] The resonant cavity (115) helps generate and amplify microwaves by causing the electrons to repeatedly stimulate the electric field inside the resonant cavity as the time the electrons stay increases as they are rotated around the magnet (120). For example, without the magnet, the electrons are immediately absorbed by the positive electrode and cannot produce the effect of the electric field, making microwave generation impossible.

[0063] The microwave generated in the above-mentioned resonant cavity (115) is emitted externally through the output antenna (125). That is, the electromagnetic wave amplified to a specific frequency inside the resonant cavity (115) is transmitted to the output antenna (125) through the output coupler. Thus, the output antenna (125) transmits the microwave to an external system (e.g., radar, medical device) through a waveguide.

[0064] The resonant frequency within the resonant cavity (115) can be expressed by the resonant frequency formula. The resonant cavity (115) is generally associated with frequency f.

[0069] The magnet (120) generates a strong magnetic field to cause electrons emitted from the negative electrode to move along a circular orbit rather than moving in a straight line. The magnet (120) consists of a permanent magnet or an electromagnet installed outside the positive electrode of the magnetron. The magnetic field controls the movement of electrons to enable the generation of electromagnetic waves within the resonant cavity, and the spiral trajectory of the electrons enables efficient microwave generation.

[0070] The magnet (120) above rotates electrons around the resonant cavity, increasing the time the electrons stay in the cavity. This causes the electrons to repeatedly stimulate the electric field inside the resonant cavity, thereby helping to generate and amplify microwaves. For example, without the magnet, electrons are immediately absorbed by the positive electrode and cannot produce an electric field effect, making microwave generation impossible.

[0071] The magnet (120) above forms magnetic field lines for electrons. The magnetic force is expressed as [Equation 4] by the Lorentz force law.

[0079] The output antenna (125) emits microwaves generated in the resonant cavity to the outside. This output antenna (125) is connected to a waveguide that guides microwaves in a specific direction inside the magnetron.

[0080] The output antenna (125) transmits microwaves output through a waveguide to an external device (e.g., radar, medical device), and is designed to be optimized to maximize the stability and efficiency of the output.

[0081] The electromagnetic wave emission of the output antenna (125) can be expressed in relation to the antenna gain as in [Equation 5].

[0082] [Mathematical Formula 5]

[0083]

[0084] G: Antenna gain,

[0085] A: Antenna area,

[0086] λ: wavelength,

[0087] The structure of the output antenna (125) above is as shown in FIG. 2b. The output antenna (125) performs the function of emitting electromagnetic signals from the heater (100) to the outside. The output antenna (125) mainly has a circular structure and radiates high-frequency energy generated inside the output antenna (125) in a specific direction to provide a signal necessary for work using it.

[0088] As shown in FIG. 2b, the dimensions corresponding to the upper part of the output antenna (125) represent the size of the connection part or the length of the fixing pin. The dimensions of 5.0 mm and 2.0 mm are designed so that the antenna fits precisely when combined with the magnetron body, allowing microwaves to be transmitted without loss.

[0089] The vertical length of the output antenna (125) is 12.0 mm and is designed to take into account the mechanical stability of the output antenna (125) and the efficiency of microwave emission. Only when this length is properly adjusted can microwave emission be optimized and the radiation pattern be maintained uniformly.

[0090] The height of the output antenna (125) is 18.0 mm, and the output antenna (125) provides sufficient space to emit electromagnetic waves generated by the magnetron to the outside. This dimension ensures stable signal emission without interference with the antenna's position and other components.

[0091] As described above, the output antenna (125) radiates high-frequency electromagnetic waves generated by the heater (100) into the external environment. This allows microwaves required for radar, microwave ovens, etc., to be efficiently transmitted. The design and dimensions of the output antenna (125) are very important factors as they determine the strength and direction of the radiated signal. In addition, the circular structure helps to ensure uniform emission of electromagnetic waves so that they are radiated only in a specific direction.

[0092] Accordingly, the output antenna (125) is an important component of the heater (100), and maximizes microwave emission efficiency according to the above dimensions and structural characteristics, and implements the designed performance exactly.

[0093] The cooling unit (130) releases heat generated during the operation of the magnetron to maintain the stability of the heater (100). This cooling unit (130) is designed in an air-cooled or water-cooled manner, and water cooling is mainly used in high-output magnetrons.

[0094] The cooling unit (130) maintains the high heat generated when the cathode and anode are in operation.

[0095] In one embodiment, the cooling unit (130) is installed around the cathode (105) and the anode (110) in the form of an air-cooled or water-cooled cooling system to release heat generated during operation.

[0096] In one embodiment, the cooling unit (130) releases heat according to the amount of heat transfer as in [Equation 6].

[0099] Q: Heat transfer rate,

[0100] k: thermal conductivity,

[0101] A: Heat transfer area,

[0102] T1: High temperature,

[0103] T2: Low temperature,

[0104] d: thickness of the material,

[0105] The output coupler (135) supports guiding a portion of the microwaves generated in the resonant cavity (115) to the output antenna and emitting them outward. The output coupler (135) is part of a waveguide connected to the output antenna and stably transmits the output signal.

[0106] This output coupler (135) is located between the resonant cavity (115) and the output antenna (125) and optimizes the directionality and efficiency of the microwave. The output coupler (135) is designed to transmit the microwave signal to the outside without distortion.

[0107] The insulator (140) provides electrical insulation between the cathode (105), the anode (110), and the power supply. This insulator (140) is made of ceramic or a high-heat-resistant insulator. The insulator (140) prevents short circuits in the internal circuit when high voltage is applied and protects the internal vacuum environment, thereby increasing electron emission efficiency.

[0108] The filter circuit (145) removes noise generated during the operation of the heater (100) and generates a pure microwave signal. The filter circuit (145) consists of a high-frequency filter and a power filter, and maintains the stability of the power input and output signals.

[0109] The vacuum chamber (150) maintains the interior of the heater (100) in a vacuum state, providing an environment in which electrons can move smoothly. This vacuum chamber (150) is designed as a sealed structure surrounding the cathode, anode, and resonant cavity.

[0110] The vacuum chamber (150) eliminates air resistance during electron movement, thereby minimizing factors that hinder the emission and movement of electrons and reducing electric field loss to increase microwave generation efficiency.

[0111] FIG. 3 is a flowchart illustrating an embodiment of the method of operating a heating device according to the present invention.

[0112] Referring to Fig. 3, in step S310, electrons emitted from the cathode stimulate the resonant cavity of the anode as they rotate in a spiral by the magnet.

[0113] In step S320, after the resonant cavity amplifies the electromagnetic wave to a specific frequency, a filter circuit removes unnecessary frequencies from the electromagnetic wave signal generated in the resonant cavity.

[0114] In step S330, when an electromagnetic wave signal is output by the filter circuit, the strength of the electromagnetic wave signal is adjusted through the output coupler.

[0115] In step S340, electromagnetic waves generated in the resonant cavity are emitted to the outside through the output antenna.

[0116] As shown in FIG. 4b, the heating housing is equipped with a cooling unit, which efficiently releases heat generated from the magnetron. The cooling unit (130) releases heat generated while the heating unit (100) is operating to the outside, thereby preventing the device from overheating. The cooling unit (130) ensures the stability of the magnetron through efficient heat management and prevents failures caused by overheating.

[0117] Several small holes are arranged in the heating housing and serve as vents for airflow. The vents expel heat generated inside the magnetron to the outside and prevent the system from overheating. Additionally, the vents ensure that internal components do not rise excessively through proper airflow.

[0118] The size of the heater housing is 71.5 ± 2.0 mm. The heater housing provides sufficient space for other components to be safely mounted inside. In addition, the size of the heater housing is appropriately adjusted according to the location or environment where the magnetron is to be installed.

[0119] The heater housing blocks electromagnetic waves and acts as an insulator to prevent high-voltage components inside the magnetron from leaking out. This plays a crucial role in enhancing the safety of the magnetron and ensuring the safety of users and the surrounding environment. Therefore, the heater housing prevents the emission of high voltage and high-frequency electromagnetic waves and protects internal components from mechanical damage.

[0120] The heating housing has a 71.5mm connection point. This secures other components and allows internal components to be safely positioned. This connection point provides mechanical stability and protects internal components from external impacts.

[0121] In other words, the heater housing interacts with internal components, such as the cathode, anode, and output antenna. If the heater housing is well-designed, it can increase the electromagnetic emission efficiency of the magnetron and properly dissipate heat, thereby maximizing the performance of the device.

[0122] Although the present invention has been described by the embodiments and drawings described above, the present invention is not limited to the above embodiments, and various modifications and variations are possible from this description by those skilled in the art to which the present invention pertains. Accordingly, the concept of the present invention should be understood only by the claims set forth below, and all equivalent or analogous variations thereof shall be considered to fall within the scope of the concept of the present invention.

[0123] FIGS. 4a and FIGS. 4b are drawings for explaining the housing of a heater according to one embodiment of the present invention.

[0124] Referring to FIGS. 4a and 4b, the top and side dimensions of the heater housing are 64 ± 0.5 mm and 60 ± 0.5 mm, respectively, as shown in FIG. 4a. This heater housing is designed with a structure in which internal components act as shields for internal electronic devices and electromagnetic waves from the external environment, and dissipate heat. The top structure also serves to facilitate heat dissipation by taking into account airflow.
