Description

Microwave radiation system for microwave whole body thermotherapy

Technical Field

The utility model belongs to the technical field of medical equipment, a human heating treatment technique is related to, in particular to a device for carrying out whole-body heating treatment to the human body.

Background

Thermotherapy is a method for artificially raising body temperature to kill diseased cells or activate the immune system of the body to prevent and treat diseases, and has the functions of activating immune function, improving basal metabolism, improving blood circulation, assisting radiotherapy and chemotherapy, selectively killing tumor cells and the like.

The existing thermotherapy methods include biological method, extracorporeal circulation heating method, body surface conduction heating method, and external radiation method. The biological method induces the body to generate heat by injecting toxin and bacteria into the body of a patient, and has great safety problem because the heating time and temperature are uncontrollable; the extracorporeal circulation warming method is to draw blood out of body with blood pump, heat to certain temperature and return to body, and belongs to invasive treatment. The body surface conduction heating method is a treatment method in which a heat source medium is directly contacted with a human body to transfer heat into the human body, such as a blanket wrapping method, a hot water bath method, and the like, and it is difficult to achieve an intended effect because the core temperature of the heated object in the body cannot be rapidly and effectively raised.

The external radiation method is a thermal therapy method for raising the temperature of human tissue by irradiating the human body from the outside of the human body using electromagnetic waves having permeability to the human tissue as radiation signals, and radiation sources mainly include infrared and microwave. The method utilizes the penetrability of radiation signals to directly heat the internal tissues of the human body, is easier to reach the target temperature compared with a heating mode of heating the skin and then conducting the skin inwards, belongs to non-invasive therapy, has relatively low risk and small side effect, and therefore, the external radiation method is an important method adopted by the existing thermotherapy.

However, since the external radiation method directly heats the tissue inside the human body by utilizing the penetrability of electromagnetic waves, the temperature of the target site inside the human body is difficult to monitor without invading the human body. Although it is possible to determine by trial and error how long a particular device is irradiated at what radiation power to achieve the target effect, it is still difficult to grasp the treatment effect due to individual differences of patients and there is a certain risk that, in order to prevent and control the risk, the radiation power and the radiation time of the device must be set below the ideal values found by the experimental conclusions, with the result that the target treatment effect is difficult to achieve.

An alternative solution to this problem is: the whole body of a patient is uniformly heated, the body temperature is monitored by adopting a conventional body temperature detection method (detecting the oral cavity temperature, the submerged temperature, the temperature in the anus and the like), and the output power and the working time of the thermal therapy equipment are intelligently controlled according to the real-time body temperature, so that the human body is accurately controlled at the target temperature, and an ideal thermal therapy target is realized while the risk is effectively prevented and controlled.

The difficulty with this solution is how to achieve uniform warming of the entire body of the human body.

Aiming at the problem of how to realize uniform heating of the whole body of a human body, the infrared whole body thermotherapy equipment adopts the solution that infrared radiators are uniformly arranged, such as thermotherapy devices disclosed in Chinese patent publication Nos. CN2621638 and CN2618571, and the infrared heat source whole body thermotherapy machine disclosed in the Chinese patent application publication No. CN109985312A is also used for enhancing the uniformity of infrared rays irradiated to the human body by diffuse reflection based on the optical characteristics of the infrared radiators on the basis of uniform arrangement of the infrared radiators.

However, the infrared ray has a weak ability to penetrate human tissue, and even near infrared ray (or short wave infrared ray, wavelength 0.76-1.5 μm) has a penetration depth of only 5-10 mm (design and implementation of photoelectric protection control, chenkuxu, graduation design of south-fill institute of occupational technology, 11/7/2013). Therefore, the infrared thermotherapy instrument has the problem of serious uneven longitudinal heating when used for carrying out whole body thermotherapy, and the situation that the monitored internal body temperature of a human body is low, but the body surface temperature exceeds the skin bearing limit, so that the body surface is easily scalded due to urgent operation. In practice, in order to prevent body surface scald, only low-power slow heating mode can be adopted, so that the whole body thermotherapy adopting infrared radiation has very slow whole body temperature rise process.

Compared with infrared rays with poor human body penetrating capability, microwaves have better penetrability to the human body and can relatively deeply penetrate into the human body. The microwave is adopted to irradiate the human body for thermal therapy, so that the problem of serious and uneven longitudinal heating can be effectively solved. However, the microwave type thermal therapy apparatus has not yet provided an effective solution to the problem of how to achieve uniform heating of the whole body of a human body. Also for this reason, the microwave thermal treatment apparatuses currently on the market are all devices for local thermal treatment (such as BSD-400 type devices and BSD-2000 type thermal treatment machines manufactured by a certain company in the united states; RF-8 thermal treatment machines manufactured by a certain company in japan; UHR-2000 type thermal treatment machines manufactured by a certain company in the south of hu; SR1000 tumor microwave thermal treatment machine system manufactured by a certain company in shenzhen, etc.).

The existing microwave thermotherapy radiating head has the characteristics of narrow wave beam, strong directivity, concentrated radiation range, fast attenuation of radiation intensity from the center to the edge in the radiation range and the like, can be suitable for local thermotherapy, but is difficult to be suitable for whole body thermotherapy.

If the solution of uniformly arranging infrared radiators is given by referring to infrared whole-body thermotherapy equipment, a large number of existing microwave thermotherapy radiation heads are uniformly arranged to realize microwave radiation whole-body thermotherapy, on one hand, the equipment cost can be seriously increased, on the other hand, due to the characteristic that the field intensity distribution center of a microwave antenna in a radiation range is strong and is rapidly weakened to the edge, the problems that the central temperature of an irradiation area of each radiation head is high and the edge temperature is low can exist, and the problem can lead the comprehensive body temperature of the whole body not to meet the treatment requirement, and the center of the irradiation area of each radiation head exceeds the bearing limit of human tissues.

How to realize microwave radiation whole body thermotherapy is a technical problem which is not solved at present.

Detailed Description

The technical solution disclosed in the present invention is further explained and explained with reference to the drawings.

Referring to fig. 1, the reason why the microwave antenna is difficult to uniformly heat the human body is mainly two-fold, and in the first aspect, the electric field distribution of the microwave antenna has the characteristics of high central strength and rapid weakening towards the edge. That is, in the radiation range of the microwave antenna, the radiation intensity of the beam b2 near the edge is significantly weaker than the radiation intensity of the beam b1 near the 90-degree direction, and therefore, in the region where the human body is irradiated, the temperature of the portion near the edge is raised more slowly than the portion near the center, resulting in temperature unevenness of different portions. In the second aspect, since the cross-sectional shape of the human body is approximately elliptical, the incident angle θ 2 of the beam b3 near the edge of the antenna radiation range to the human body is larger than the incident angle θ 1 of the beam b1 near the 90-degree direction to the human body, and therefore, the radiation efficiency of the beam b3 near the edge of the antenna radiation range is lower than that of the beam b1 near the 90-degree direction, and it is determined that the temperature rising speed is fast when the human body is radiated toward the front of the antenna, and the temperature rising speed is slow when the parts closer to the two sides are radiated. The two factors are superposed, so that the problem of uneven heating of the microwave radiation thermotherapy is further aggravated.

Similarly, the radial section radiation angle of each antenna array is larger than the corresponding included angle of the target human body area. The supplemental beam of each antenna array reinforces the portion between the two adjacent antenna arrays where the radiation intensity is relatively weak.
