Description

TECHNICAL FIELD

[0001] The utility model relates to a tumor electric field treatment device and electric field generating device thereof. BACKGROUND

[0002] At present, the treatment methods of tumors mainly include surgery, radiotherapy, chemotherapy and the like, but all have corresponding shortcomings, such as side effects of radiotherapy and chemotherapy, and killing of normal cells. The use of electric field to treat tumors is also one of the current research frontiers, and tumor electric field treatment is a tumor treatment method that generates an electric field through a special electric field generator to interfere with the mitotic process of tumor cells at low intensity and high frequency. Studies have shown that electric field treatment has a significant effect in the treatment of diseases such as glioblastoma, non-small cell lung cancer and malignant pleural mesothelioma. The electric field applied by this method can affect the aggregation of tubulin, prevent spindle formation, inhibit the mitotic process, and induce apoptosis of cancer cells. At the same time, the electric field intensity and the use time become key factors in the treatment process.

[0003] A common tumor electric field treatment device for tumor electric field treatment includes an electric field generating device and a pair of electrode patches. The electrode patches are attached to the body surface at the tissue region where the patient's lesion is located. The electric field generating device generates an alternating current signal and transmits the alternating current signal to the electrode patches to alternately generate an alternating electric field between each pair of electrode patches, thereby treating the tissue region where the patient's lesion is located. Chinese Utility Model Patent No. CN216536557U discloses an electric field generating device including a housing, a main control board, a fan, a battery and the like. The housing includes a front cover, a rear cover, an upper shell and a lower shell. The main control board, the fan and the battery compartment for installing the battery to supply power to the main control board are fixed in the housing. To ensure the close combination and assembly stability of the housing and the main control board, screws are mostly used for connection. If all are fixed by screws, corresponding screw holes, studs and screw installation operation spaces need to be designed, which results in time-consuming assembly process and affects assembly efficiency.

[0004] Therefore, it is necessary to improve the existing tumor electric field treatment device and electric field generating device thereof. UTILITY MODEL CONTENTS
