Problems solved by technology

This type of device has the following deficiencies: 1. The penetration depth of far-infrared rays is extremely shallow, neither can penetrate the skin, nor can it penetrate subcutaneous fat and muscle tissue. hot
2. Prolonged exposure to temperatures above 46°C will cause skin burns in most parts of the human body, while cells in muscles and other tissues will partially die at 43°C. Therefore, the temperature in the infrared cabin must be limited to 45°C. below ℃
The normal body temperature of the human body is 37°C, and the temperature difference is only about 8°C, which determines that the above-mentioned heat transfer process is very slow, the temperature rises very slowly, and the heating time is very long
3. It is unbearable for the patient's body to be placed in a sealed infrared cabin at around 45°C for a long time
Therefore, the patient must be administered general anesthesia for treatment, which poses additional risks
4. This kind of whole body hyperthermia equipment cannot be used for regional deep hyperthermia, which has great limitations

Embodiment 1

[0021] Embodiment 1: Microwave whole-body or regional heating method, output 30 phase-independent microwaves from an incoherent microwave source and send them to 30 array elements corresponding to the electromagnetic lens antenna array, each array element is more evenly distributed around the human body and in the A pseudo-uniform microwave field is formed around the human body, and the distribution or uniformity of the microwave field is adjusted by means of electrical scanning to implement whole-body or regional deep heating. See the following embodiment 2 for relevant working parameters.

Embodiment 2

[0022] Example 2: Microwave whole body or area heating devices such as figure 1 As shown, it includes an incoherent microwave source 2, an electromagnetic lens antenna array 1, a computer information processing system 3, and a temperature measurement system 4, and the electromagnetic lens antenna array 1 is installed on figure 2 Shown support frame 5 (this support frame is made of figure 2 The shown bottom frame and the upper frame above it are composed of 30 array elements 6, and the incoherent microwave source 2 has corresponding 30 output ports, outputting 30 phase-independent microwaves, with a total output power ≤ 3.0KW , and the output power sent to each port is <400W; the operating frequency is 2.45G (can be selected in the range of 0.5-10G); each element of the electromagnetic lens antenna array 1 is composed of a radiator and an electromagnetic lens, each Each array element 6 is correspondingly connected with an output port of the incoherent microwave source 2, and...

Abstract

A microwave method for heating whole or local body features that the multiple channels of microwave are output from noncoherent microwave sources to the electromagnetic lens antenna array consisting of multiple electromagnetic lenses to generate a pseudounifor microwave field around human body, and its uniformity is regulated by electric scanning for heating whole or local body. Its apparatus is composed of an electromagnetic lens antenna array, noncoherent microwave sources, temp measuring system consisting of temp sensors, and computer control unit.

Description

technical field [0001] The invention relates to a method and a device for whole body or regional heating of a human body by microwaves. Background technique [0002] Hyperthermia has become one of the important methods in the comprehensive treatment of advanced cancer, and whole body hyperthermia is also more widely used by doctors. Traditional whole-body hyperthermia devices at home and abroad all use far-infrared heating systems, which are four walls of cabin-shaped devices that distribute far-infrared heating materials. This small cabin can accommodate one person lying in it, leaving only the head outside the small cabin. The far-infrared devices distributed on the four walls emit far-infrared waves to heat the skin of the human trunk and limbs. Due to the effect of heat conduction, the heat of the skin is gradually transferred to the subcutaneous fat and muscle tissue. As the temperature of the muscle tissue rises slowly, the blood in the muscle tissue is also heated, ...
