Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to an energy focusing structure and a treatment device thereof. Background Art

[0002] Currently, in the medical field, some research results have been achieved in using microwaves or millimeter waves to relieve pain. The principle of a millimeter wave therapy device is that millimeter waves with a specific frequency resonate with human cells, thereby affecting the physiological functions of cells. In some medical scenarios, it is used to relieve pain, promote wound healing, etc. For example, in the treatment of soft tissue injuries, the energy of millimeter waves can stimulate the metabolism of local cells and accelerate the repair process of damaged tissues. For some chronic pain diseases, such as arthritis, the millimeter wave therapy device may reduce the patient's pain perception by regulating nerve conduction and local inflammatory responses.

[0003] The paper published by Oxford University Press in 2006: "Low-Intensity Electromagnetic Millimeter Waves for Pain Therapy, doi:10.1093 / ecam / nel012" proves that electromagnetic wave signals in the low-energy millimeter wave and microwave frequency bands can reduce pain through mechanisms such as local body heating, resonance of the body, blood, and ganglion structures.

[0004] The paper published by the University of Cambridge in 2011: "Millimeter-wave interactions with the human body: state of knowledge and recent advances", doi:10.1017 / S1759078711000122, focuses on analyzing the research results in the electromagnetic, thermal, and biological aspects in the range of 30 - 100 GHz, especially within 60 GHz.

[0005] The paper published in 2017: "Transmission Array of a Focused Microwave Thermotherapy System for Leg Diseases", doi: 10.1109 / APEMC.2017.7975466, discusses the functions and mechanisms of a microwave thermotherapy system, and the experimental results prove that electromagnetic wave thermotherapy has a certain therapeutic effect on leg diseases.

[0006] The adjuvant therapy products of German company ENOVIS (website: https: / / enovis.com) also generate electromagnetic waves or magnetic fields through active circuits and act on the lesion area, or encapsulate the active circuit and a loop antenna into forms such as knee pads and lumbar supports, which are fixedly worn on different parts of the body to produce therapeutic effects.

[0007] Existing products usually need to generate corresponding electromagnetic wave signals through an external power supply for treatment. Due to limited usage scenarios, they are inconvenient to carry, have high manufacturing costs and failure rates. Researchers are trying to generate electromagnetic waves through passive devices to inhibit pain. The researchers mainly conduct research through Transmit array Antenna (TMA). TMA technology usually requires a radio frequency source to be set at the focus of the TMA lens to form a planar beam. In medical applications, irregularly scattered electromagnetic waves need to be focused, and in addition, medium matching for the skin and body needs to be achieved to avoid a large amount of reflection and energy loss of electromagnetic waves on the skin surface. In TMA design, a common method is to arrange similar unit structures periodically, usually at intervals of a quarter wavelength, to direct electromagnetic waves. Some designs provide tunable devices on the unit structure to achieve program control.

[0008] A paper published in IEEE in 2022: 《A Brief Review and Comparison Between Transmitarray Antennas, Reflectarray Antennas and Reconfigurable Intelligent Surfaces》, doi: 10.1109 / TOCS56154.2022.10016145. This paper studied the advantages and disadvantages of TMA technology. TMA technology has unique advantages in millimeter-wave application scenarios due to its characteristics of high frequency, narrow bandwidth, and using feed.

[0009] US Patent No. US10707570 reveals a passive pain relief technology. By setting a patch coated with capacitive material, the patch includes capacitive material and provides additional capacitance to reduce the conduction of nerve electrical signals. This product does not require power supply, but needs to be placed on the path extending from the pain area to the cranial nerve. The pain inhibition mechanism for deep pain points in the technical solution is not obvious.

[0010] The paper "A Compact PCB Gasket for Waveguide Leakage Suppression at 110 - 170 GHz" published in IEEE in 2020, doi: 10.1109 / IMS30576.2020.9224023, proposed a thin - film structure for near - field electromagnetic wave control. The design application scenario of this solution is different from that of the present invention, and this design is also achieved by periodically arranging unit structures.

[0011] However, in today's society, especially in cities, electromagnetic wave radiations of different frequency bands such as Wi - Fi, mobile networks, FM, and satellite GPS widely exist. How to focus various electromagnetic wave radiations in space and form a planar beam, and then relieve pain and assist in treatment, has become a research topic worthy of study.

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Please refer to Figure 1 A cross-sectional view of the energy focusing of the first embodiment of the present invention. The energy focusing structure of the present invention is composed of a surface metal layer 101, a base PTFE layer (Poly tetrafluoroethylene) 102 and a VIA via 103. Metal layers 101 are arranged on the upper and lower surfaces of the base PTFE layer 102. Metal patterns are provided on the surface of the metal layer 101. Further, the upper and lower layers are connected by the VIA via 103. The typical thickness of the base PTFE layer is 0.125 mm - 1 mm, and the metal patterns can be adjusted according to the thickness of the base PTFE layer as needed.

[0032] Preferably, PTFE coatings with a thickness of not more than 0.25 mm can be added to the upper and lower surfaces of the base PTFE layer 102 respectively, and the PTFE coatings can play a role in protecting the internal patterns.

[0033] Figure 2 is a cross-sectional view of the energy focusing structure of the second embodiment of the present invention. On the basis of Figure 1 , two layers of base PTFE layers are stacked as the base, and circular or other-shaped metal patterns are arranged on the upper and lower layers respectively. The size of the metal patterns changes with the pattern position. The energy focusing structure is composed of four TMA sub-arrays. Each TMA sub-array is composed of four similar 64-element TMAs. The radius parameter of each matrix is generated by a fourth-order Bessel function in cooperation with the radio frequency simulation results. A 3% random error is added to each generated radius size matrix, thereby reducing the antenna side lobe.

[0034] Each of the TMA sub-arrays is composed of circular metal antenna elements. The radius sizes (unit: mm) of the circular metal antenna elements are shown in the following table. The element spacing is 8 mm, and the outermost spacing is connected by vias, and there are no vias for the middle elements:

[0035] Further refer to Figure 3 The radio frequency simulation schematic diagram of the energy focusing structure of the present invention, Figure 4 The side simulation schematic diagram of the energy focusing structure of the present invention, Figure 5 The radiation schematic diagram of the energy focusing structure of the present invention and Figure 6Electric field distribution diagram of the energy focusing structure of the present invention. The operating frequency of the energy focusing structure of the present invention is 0.3 - 6.8 GHz. It can be found through radio frequency simulation at a frequency of 5.8 GHz that for a parallel beam radiation source, the energy focusing structure of the present invention produces a concentrated focusing effect. For the skin medium, the penetration ability exceeds 15 cm. The side simulation results prove that the energy after aggregation is about 0.2 V / m, which meets the national electromagnetic compatibility standard and has beneficial effects.

[0036] Furthermore, the energy focusing structure of the present invention is sewn onto protective devices such as knee pads, neck guards, and lumbar supports to form a treatment device with an internal energy focusing structure, enabling the energy focusing structure to be close to the skin. In daily life, energy can be guided into the painful area through electromagnetic wave focusing. The energy focusing structure can also be sewn into products such as band-aid tapes to promote local wound healing or relieve pain.

[0037] Due to the passive design of the energy focusing structure of the present invention, the application scenarios include but are not limited to wearable products in the civilian field, such as clothing, bedding, etc.; various transportation seats, sofas, etc. in public places; cold-proof and warm-keeping clothing and facilities in the military field; various patch products in the medical field; promoting seed germination and greenhouse facilities in the agricultural field and water treatment; and various patch products in the medical beauty field. In these fields, by adopting the energy focusing structure of the present invention, the comfort of users, the yield of crops, the wound healing speed, the drug absorption effect, etc. can be effectively improved. The applicant will not enumerate them here.

[0038] The present invention uses a flexible material to form a pain inhibition patch, and realizes the filtering and focusing of environmental electromagnetic waves through a special antenna layout design, so as to achieve the purpose of a low-energy electromagnetic wave therapeutic instrument. The patch directly acts on the surface of the diseased skin, and the passive design is easy to place.

[0039] The center frequency of the energy focusing structure of the present invention is related to the element size. This design can change the element size and perform electromagnetic simulation to change the treatment frequency, so as to improve the auxiliary treatment effect for different lesions.

[0040] The energy focusing mechanism of the present invention has a wide range of application scenarios, and the production materials are not limited to PTFE and metals, but can also be various composite materials, such as any one or a combination of steel alloys, magnesium alloys, aluminum alloys, copper alloys, composite plastics, crystals, meteorites, or bian stones, or can also be a plate made of a low electromagnetic loss composite material.
