Description

Microwave radiation whole body thermotherapy device

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 heating treatment to the human body.

Background

The heat treatment is a method for quickly and uniformly raising the temperature of a human body by means of external energy so as to kill diseased cells or activate the immune system of the body to work and further treat diseases, and has the effects of activating the immune function, improving the basal metabolism, improving the blood circulation, assisting the radiotherapy and chemotherapy, selectively killing tumor cells and the like. The thermal therapy can be divided into local thermal therapy and whole body thermal therapy in terms of treatment form. Local hyperthermia is suitable for targeted treatment of local lesions, such as local pain, benign tumors, etc. The whole body thermotherapy is not only suitable for treating local focus, but also has good adjuvant therapy effect on the whole body diseases with seriously damaged immunologic function, such as large-scale operation, diabetes late stage, late stage diffuse type tumor, AIDS and the like. In particular to high-temperature whole-body thermal therapy of tumors, which kills tumor cells by changing the temperature of a human body without damaging normal tissues and has small side effect compared with radiotherapy, chemotherapy and the like, thereby being worthy of green therapy in clinic.

The existing thermotherapy methods include biological method, body surface conduction heating method, extracorporeal circulation heating method, and extracorporeal 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 body surface conduction heating method is a treatment method of directly contacting a human body by utilizing a heat source medium to transfer heat into the human body, such as a blanket wrapping method, a hot water bath method and the like, and has the defects of overlong heating time and very limited effect, and cannot quickly and effectively increase the core temperature of a heating object; 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 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 with electromagnetic waves having permeability to the human tissue, and radiation sources suitable for the external radiation method mainly include infrared and microwave. The external radiation method belongs to non-invasive therapy, has relatively low risk and small side effect, and is an important method adopted by the existing thermotherapy.

For hyperthermia by external radiation, the disadvantages of local hyperthermia are twofold. On one hand: the subcutaneous fat tissue of human body has rare blood vessels and poor heat dissipation capability, and the temperature rise speed of the fat tissue is faster than that of muscle tissue and viscera tissue under the condition of simultaneously absorbing the energy of the radiation source. After a period of heating by a single or local radiation source, the tumor tissue in the deep part has not reached the effective treatment temperature (42.5 ℃), while the adipose tissue near the polar plate has reached the tolerance limit (45 ℃), and if the heating is continued, the adipose tissue in the vicinity of the polar plate can be burnt by hard fat, so that the overheating of fat can be relieved only by stopping the machine or reducing the power, but the curative effect is seriously influenced. On the other hand: since the external radiation method directly heats the internal tissues of the human body by using the penetrability of electromagnetic waves, the temperature of the target part in the human body is difficult to monitor on the premise of not 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.

Theoretically, whole body thermotherapy can avoid the problem of temperature rise speed difference between adipose tissues and other tissues, and meanwhile, the body temperature can be monitored by adopting a conventional body temperature detection method (detecting oral cavity temperature, submerged temperature, intra-anal temperature and the like), but the premise is that the whole body is heated to be uniform enough.

The existing whole body thermotherapy equipment based on the external radiation method in the market at present is infrared radiation thermotherapy equipment, but the infrared ray has weaker ability to penetrate human tissues, and even if the infrared ray is near infrared ray (or short-wave infrared ray with the wavelength of 0.76-1.5 mu m), the penetration depth of the infrared ray into the human tissues is only 5-10 mm (design and realization of photoelectric protection control, Chenqixu, the graduation design of the southern charging institute of technology, 2013, 11 months and 7 days). Therefore, the infrared thermotherapy instrument has the problem of serious uneven longitudinal heating when used for carrying out whole body thermotherapy, and the condition that the monitored body temperature is low but the body surface temperature exceeds the skin bearing limit exists, 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 penetrating power, the microwave has better penetrability and can relatively deeply penetrate into a human body. The microwave is adopted to irradiate the human body for thermal therapy, so that the problem of uneven longitudinal temperature can be effectively solved. However, the existing microwave thermotherapy radiation head has the characteristics of narrow 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. Therefore, the microwave thermotherapy instruments currently on the market are all devices for local thermotherapy (such as BSD-400 type devices and BSD-2000 type thermotherapy machines manufactured by certain American company, RF-8 thermotherapy machine manufactured by certain Japan company, UHR-2000 type thermotherapy machine manufactured by certain Hunan company, SR1000 tumor microwave thermotherapy machine system manufactured by certain Shenzhen company, and the like).

If a large number of existing microwave thermotherapy radiating heads are used in combination to realize whole body thermotherapy, the problems of concentrated central temperature and low edge temperature of the radiating head radiating area exist, and the problem can cause the situation that the comprehensive body temperature of the whole body does not meet the treatment requirement, and the center of each radiating head radiating area exceeds the bearing limit of human tissues. How to realize microwave whole body thermotherapy is still an unsolved technical problem at present.

Detailed Description

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.
