Problems solved by technology

[0005] The purpose of the present invention is to provide a non-invasive radiative whole-body hyperthermia method with body surface cooling. For the first time, the combined effect of cooling on the human body surface and deep radiation is used to increase the heating range, thereby avoiding body surface burns as much as possible. The heat is introduced into the body to solve the problem of easy burns on the body surface in the existing radiant whole-body hyperthermia

Embodiment Construction

[0027] The present invention for the first time improves the heating range by means of the combined effect of cooling on the human body surface and deep radiation, so as to introduce heat into the body as much as possible under the premise of avoiding body surface burns. The heating of the body results from the energy of the focused radiation source and the heat absorption and conduction of the tissues. The exponential distribution of radiation energy from the outer layer to the body core and its energy accumulation on the body surface limit the total radiation energy. Increasing radiant power will cause excess energy and burns on the body surface. In order to avoid body surface burns, the total radiation energy must be reduced, resulting in a decrease in heating efficiency. Therefore, the present invention adopts body surface cooling measures through ice packs, cold water bags, phase-change materials and low-temperature cooling fluid circulation system to improve the accepta...

Abstract

The invention relates to a surface-cooling non-invasive radiation whole-body thermocuring method, in particular to a non-invasive radiation whole-body thermocuring method by introducing a large amount of radiation power into the deep issues of human bodies quickly through surface-cooling technology to prevent surfaces from being burned and increase radiation power. In the method, a radiation heating system is combined with a surface-cooling system, so that low-attenuation electromagnetic radiation on the surfaces is taken away, and high dose of infrared, microwaves, radio frequency and energyradiation of electromagnetic wave probes of each frequency range are radiated to the deep parts of the human bodies for heating to realize the non-invasive radiation whole-body thermocuring. The method breaks through the technical route that improvement is performed through aspects of a heating mode, heat source control and the like in the prior art technically, introduces ultralow-temperature cooling for the first time to offset the local radiation of the surfaces and prevent overheating and empyrosis; simultaneously, the non-invasive radiation whole-body thermocuring is performed by utilizing a deep radiation heating source so as to improve power which can be accepted by organisms and prevent the surfaces from being burned substantially.

Description

technical field [0001] The present invention relates to a medical method, in particular to a method of rapidly introducing a large amount of radiation power into the deep tissue of the human body by using body surface cooling technology, avoiding burns on the body surface and increasing the radiation power, and a non-invasive radiation whole-body hyperthermia method, which is especially suitable for tumors Whole-body hyperthermia in patients. Background technique [0002] At present, among various major diseases faced by human beings, malignant tumors are one of the most lethal diseases. It is against this background that whole body hyperthermia came into being. This method achieves tumor treatment by raising the body temperature to 39-43°C and triggering secondary biological effects. The mechanism of whole-body hyperthermia is to selectively kill cancer cells by artificially raising body temperature by using thermal effects. It is a promising treatment method for controlli...
