Description
The technical field is as follows:
the invention relates to the field of medical instruments, in particular to a device for diagnosing acute radioactive skin injury.
Background art:
radiotherapy is one of the important means for treating malignant tumor, but it can kill cancer cell effectively and damage normal tissue. In the course of radiotherapy, the skin of the irradiated part is easily damaged by radiation, which is a common complication of radiotherapy. The acute skin injury is effectively prevented and treated, so that the pain of a patient can be reduced, the treatment continuity can be ensured, and the radiotherapy effect is improved. The diagnosis of acute radiation skin injury is mainly based on the irradiated dose and the gradually displayed skin performance, but the irradiation conditions are different due to different ray energies, so that it is difficult to provide a correct universal threshold dose, and the clinical performance is complicated.
Medical research shows that in the early stage of the formation of various diseases, single cells or cell groups of local focuses of a human body begin to generate temperature changes, and the changes are represented by the temperature increase or temperature decrease of the single cells or the cell groups, or the diseases are developed to different degrees along with the increase of abnormal cells and the spread of abnormal temperatures. The change of the temperature of the cells in the early stage of the temperature change is unconscious by the human body, and the self-symptoms which can be detected by the human body are formed only after the abnormal cell temperature reaches a certain amount. The infrared thermal imaging technology can diagnose diseases through the abnormal change of the distribution of the body surface thermal field when the function of human tissues has abnormal physiological changes, and can condition the diseases early in the development of the diseases.
At present, a functional imaging device commonly used in clinic is a thermal infrared imager, and because many factors influencing the distribution of a body surface thermal field and the temperature change exist, a thermography analysis doctor needs to closely combine with other clinical information to eliminate a plurality of interference factors so as to make a diagnosis. Therefore, part of the existing infrared thermal imaging equipment adopts a sealed cabin body and is provided with a constant temperature system, so that the interference of external environmental factors on thermal imaging is reduced, and simultaneously, certain psychological influences of the external factors on patients are reduced, such as stress, anxiety and other psychological influences on the blood circulation state of human bodies, and the inspection results are influenced. The existing cabin body type infrared thermal imaging equipment has narrow cabin door size, is convenient for a single person to get in and out, can quickly form a closed inspection space in the cabin after the door is closed so as to isolate the external temperature and quickly keep the temperature in the cabin constant, and can also protect the privacy of a patient during the clothes removal inspection. However, for some patients with mobility disabilities, after entering the cabin with the help of medical staff, a stool chair needs to be prepared to facilitate subsequent examination of the patient. After the examination, the stool chair needs to be folded to a certain fixed position, and the examination of other following patients cannot be influenced, for example, some patients need to swing postures such as arm stretching and bow positions, so that the existing cabin type infrared thermal imaging equipment cannot meet the requirement of special patients during examination.
