Horizontal electric field RF heat therapy equipment

Abstract

The horizontal electric field RF heat therapy equipment includes one RF power source, one power feeding circuit, feeders and one resonant cavity. The RF power source is connected through the power feeding circuit to feeders distributed on the resonant cavity; and the resonant cavity includes lockable metal casing and two serial tubular conductors inside the casing. The feeders may be set in different modes, and are preferably connected to both the metal casing and one tubular conductor through insulator in the metal casing. The resonant cavity of the RF heat therapy equipment can generate electric field parallel to human body surface in the body surface layer of the patient and has raised use efficiency and wide applicable use range.

Description

1. Technical field: [0001] The invention belongs to the field of medical physical therapy, and in particular relates to a device for treating diseases by using radio frequency energy. 2. Background technology: [0002] At present, hyperthermia technology has been widely used in the clinic of various diseases, such as gastric cancer, lung cancer, pancreatic cancer, etc., which can be divided into two types: biological hyperthermia and physical hyperthermia. Among them, biological hyperthermia is to use microbial infection to cause self-fever in patients, such as using Plasmodium to cause patients to suffer from malaria and cause fever (Chinese patent named "Using Plasmodium to obtain safe high fever and related clinical parameters of human body", publication number CN1432407A ). Physical hyperthermia is the use of physical methods to produce hyperthermia effects. It achieves therapeutic purposes by directly generating heat in the superficial or deep parts of the patient's bo...

Problems solved by technology

[0003] Another problem existing in the existing radio frequency hyperthermia equipment is that a water bag needs to be filled between the radiator and the patient's body to facilitate the coupling of electromagnetic wave energy, and disease patients, especially those with advanced stages, are generally in poor health, and it is difficult to bear such a heavy medical device for a long time. Water bag, which makes the patient feel very painful during the treatment

[0004] The third problem of the existing radio frequency hyperthermia equipment is that only a part of the radio frequency energy generated by the radio frequency source can be transmitted into the human body, and a part will be radiated into the air, so that the medical staff will be irradiated, especially the operator of the equipment. to adversely affect
