Problems solved by technology

The radiator is still a broadband radiator, which has a large volume and low efficiency, and still does not solve the above problems
[0007] The above prior art is called microwave acupuncture in the world, and the radiators are very large in size, which is not suitable for the treatment of narrow and small acupuncture points in the human body.

Embodiment 1

[0034] like Figure 1-4 As shown, this embodiment is a schematic diagram of a microwave acupuncture radiator with a center frequency of 433 MHz. The microwave acupuncture radiator includes an open metal shield 1 and a PCB board (dielectric substrate, made of microwave dielectric ceramics) 13 fixed on the opening 3 of the metal shield by screws. The front of the PCB 13 has a microwave antenna 6, The microwave antenna 6 is a rectangular spiral microstrip line. The back or side of the metal shield 1 is provided with a feeder hole 5 through which the coaxial cable passes, and the inner conductor of the coaxial cable is electrically connected to the center of the microwave antenna 6 . Specifically, in this embodiment, the center of the back of the PCB board 13 is provided with a first pad 8, the first pad 8 is electrically connected to the center of the microwave antenna 6 through a metallized through hole 12, and the inner conductor of the coaxial cable Soldering with the first ...

Embodiment 2

[0039] like Figure 6-Figure 9 As shown, the structure of the radiator in this embodiment is the same as that in Embodiment 1, and the center frequency of the antenna is 915 MHz. Wherein, the outer ring size of the metal shielding case 1 is φ18mm, and the size of the circular PCB board is φ16mm. The parameters of the microstrip line are as follows: the line length is 95mm, the line width is 0.2mm, the resistance is about 0.35Ω, the microstrip is spirally wound 6.5 times, and the distance between adjacent microstrip lines is 0.4mm. The parameters of the microstrip line can realize the miniaturization of the microwave antenna with a center frequency of 915MHz within the following range: the line length range is 95mm±1mm, the line width range is 0.2mm±0.05mm, the resistance range is 0.35Ω±0.05Ω, the line The distance range is 0.4mm±0.05mm.

Abstract

The invention relates to a microwave acupuncture and moxibustion radiator. The microwave acupuncture and moxibustion radiator comprises a metal shield hood and a microwave antenna arranged at an opening of the metal shield hood, wherein the microwave antenna is a rectangular spiral microstrip line; and the parameters of the microstrip line are one of the two groups of the parameters: the line length is 180mm, the line width is 0.4mm, and the resistance is 0.35 Ohm + / - 0.05 Ohm, or the line length is 95mm, the line width is 0.2mm, and the resistance is 0.35 Ohm + / - 0.05 Ohm. According to the microwave acupuncture and moxibustion radiator disclosed by the invention, parameters of a microwave ceramic printed board and parameters of the microstrip line in the radiator are key technique of themicrowave acupuncture and moxibustion radiator, and performance indexes of the antenna are directly influenced; the two groups of the parameters correspond to the central frequency of 433MHz and 915MHz; the microwave antenna adopts a narrow strip design, so that the standing-wave ratio is small, the performance is high, the requirements for power are low, and high efficiency and miniaturization can be realized; the microwave acupuncture and moxibustion radiator is a microwave body surface radiator of which the dimension is the smallest in similar products in the world range at present, so thatthe microwave acupuncture and moxibustion radiator is easier to put on some narrow acupuncture points on limbs, and is more suitable for microwave acupuncture and moxibustion to use.

Description

technical field [0001] The invention relates to a microwave acupuncture radiator, in particular to a body surface non-invasive microwave radiator, which can be used for acupuncture, hyperthermia and the like. Background technique [0002] Acupuncture and moxibustion of traditional Chinese medicine originated from ancient times and has a long history. It is a treasure of traditional Chinese medicine. Acupuncture and moxibustion in traditional Chinese medicine have been used to treat diseases for thousands of years. Acupuncture has been recognized all over the world for its good curative effect and no side effects. [0003] Microwave refers to electromagnetic waves with a wavelength of 1 mm to 1000 mm and a frequency of 300 MHz to 300 GHz. Microwave technology is a new technology developed in the 20th century, and it has been widely used in communication, aerospace, medical and many other fields. Due to the thermal effect of microwave and the non-thermal effect of biochemist...
