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 operation, 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 for interfering with the mitosis process of tumor cells through a low-intensity, medium-high frequency and alternating electric field generated by a special electric field generator. Studies have shown that electric field treatment has remarkable effects 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 mitosis 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. CN219290450U discloses an electric field generating device, which includes a shell, an MCU circuit board with a socket and a battery assembly that is mutually matched with the socket, and the like.

In this embodiment, the housing (not numbered) comprises an upper shell 20, a lower shell 30 assembled with the upper shell, and an inner support 60 between the upper shell 20 and the lower shell 30. The upper shell 20 and the lower shell 30 are assembled and fixed vertically to form a cylindrical shape with open ends in front and back. The cover (not numbered) comprises a front cover assembly 10 and a rear cover assembly 40, the front cover assembly 10 is fixed at the front end opening of the upper shell 20 and the lower shell 30, and the rear cover assembly 40 is fixed at the rear end opening of the upper shell 20 and the lower shell 30. The front cover assembly 10, the upper shell 20, the lower shell 30 and the rear cover assembly 40 together form a cavity (not numbered), and the inner support 60 and the circuit boards 70 fixed on the inner support 60 are located in the cavity (not numbered). The electric field generating device 100 is also provided with a battery assembly 50 which is detachably assembled in the housing (not numbered), and the battery assembly 50 is used to power the circuit boards 70.

[0029] In combination Figure 3 and Figure 4 As shown, the inner support 60 in Figure 3 and Figure 4 is placed with the bottom surface facing upward. The inner support 60 has an upper battery compartment 61, the lower shell 30 has a lower battery compartment 31 corresponding to the upper battery compartment 61, the inner support 60 is assembled with the lower shell 30 vertically, and the upper battery compartment 61 of the inner support 60 and the lower battery compartment 31 of the lower shell 30 together form a battery compartment 101 with an opening 102 at one end. The battery assembly 50 is inserted and accommodated into the battery compartment 101 through the opening 102. The inner support 60 is provided with a through hole 62 (see Figure 6 ) communicating with the upper battery compartment 61 at the corresponding position, and a circuit board 70 is provided with a socket 71 protruding into the upper battery compartment 61 from the through hole 62. The through hole 62 and the opening 102 are located at opposite ends of the battery compartment 101, and the battery assembly 50 is inserted horizontally into the battery compartment 101 through the opening 102 and electrically connected with the socket 71 to power the circuit boards 70.

[0030] The electric field generating device 100 also includes several buffer members 90, which are disposed on corresponding portions of the housing (unlabeled) located in the battery compartment 101. In this embodiment, two buffer members 90 are respectively disposed on opposite sides of the housing (unlabeled) in the battery compartment 101, close to the socket 71. The buffer members 90 may be made of a flexible and soft material such as silicone. At least a portion of the structure of the buffer member 90 protrudes into the battery compartment 101. When the battery assembly 50 is inserted, the buffer member 90 directly contacts the battery assembly 50 to slow down the insertion or sliding speed of the battery assembly 50, thereby reducing the impact force on the battery assembly 50 and preventing damage to the socket 71 due to the impact of the battery assembly 50.

[0031] In this embodiment, the buffer member 90 is fixed to the inner bracket 60 and protrudes into the upper battery compartment 61. Specifically, the inner bracket 60 has two side walls 63 arranged opposite to each other and spaced apart, and the two side walls 63 and the corresponding parts of the inner bracket 60 surround to form the upper battery compartment 61. One buffer member 90 is fixed on each side wall 63. It is understood that there is no limit to the specific number of buffer members 90, but preferably there are an even number of buffer members 90 arranged symmetrically on the two side walls 63.

[0032] refer to Figure 5 , Figure 6 and Figure 7 As shown, please note that the inner supports 60 are all placed with their bottom surfaces facing upwards. The buffer 90 is generally a strip-shaped block structure, including a fixing part 91 and a buffer part 92 that protrudes from one side of the fixing part 91 and is generally arc-shaped. The fixing part 91 is fixed to the side wall 63, and the buffer part 92 protrudes into the upper battery compartment 61 to contact the battery assembly 50. The surface of the buffer part 92 that protrudes into the upper battery compartment 61 is arc-shaped so that the buffer part 92 does not obstruct the insertion of the battery assembly 50 when it initially contacts the battery assembly 50.
