Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a battery assembly, an electric field generating device and a tumor electric field therapeutic apparatus. Background Art

[0002] At present, the treatment methods for tumors usually include surgery, radiotherapy and chemotherapy, but they all have corresponding disadvantages. For example, radiotherapy and chemotherapy can produce side effects and kill normal cells. Using electric fields to treat tumors is also one of the current research and development frontiers. Tumor Treating Fields (TTF) is a method of applying low-intensity, medium-frequency alternating electric fields to cancer cells, thereby interfering with the process of cancer cell mitosis, inhibiting cancer cell mitosis, and inducing cancer cell apoptosis, thereby achieving a therapeutic effect. Studies have shown that electric field therapy is effective in the treatment of glioblastoma, non-small cell lung cancer, and malignant pleural mesothelioma. The electric field applied by this method can affect the aggregation of tubulin in dividing cancer cells, prevent the formation of spindles in dividing cancer cells, inhibit the mitotic process of cancer cells, and induce cancer cell apoptosis.

[0003] The electric field therapy device for treating tumors usually includes an electric field generating device and an electrode patch electrically connected to the electric field generating device. The electrode patch is applied to the skin of the human body corresponding to the lesion so that an alternating electric field is applied to the tissue area where the tumor is located for electric field tumor treatment. In order to facilitate mobility, the electric field generating device is powered by a rechargeable battery, but the battery life of a single rechargeable battery is short, about two hours. When the tumor electric field therapy device is used for a long time for tumor electric field therapy, the battery needs to be replaced regularly. The existing electric field generating device generally uses an open battery compartment to accommodate the battery. The battery is assembled on the electric field generating device in a pluggable manner and accommodated in the battery compartment. The battery can be easily replaced to ensure that the tumor electric field therapy device can continue to work for a long time. However, since the battery and battery compartment on the existing electric field generating device are usually exposed on the outside of the shell, the aesthetics is poor. In addition, dust will accumulate on the heat dissipation air intake holes on the existing electric field generating device, which will cause excessive heat. Summary of the invention

[0084] In a specific embodiment, Figure 8 , Fig. 9 As shown, the number of the battery cells 34 is one or more. When the number of the battery cells 34 is multiple, the single power supply time of the battery assembly 3 can be increased, and the structure and assembly process of the battery assembly 3 are simplified.

[0085] In a specific embodiment, Figure 1 , Figure 8 , Fig. 9 As shown, the battery assembly 3 is a rechargeable battery, which can be taken out and charged regularly when the tumor electric field therapy device is used for a long time for tumor electric field therapy, and has a simple structure and is easy to use.

[0086] In a specific embodiment, Figures 8 to 12 As shown, the locking portion 4 includes a battery lock buckle 41. The battery lock buckle 41 includes a first elastic body 411 and a plurality of lock bodies 412. Each lock body 412 is arranged along the radial direction of the top receiving groove 311 of the battery middle shell 31, and the plurality of lock bodies 412 are arranged along the circumference of the top receiving groove 311. The first end of each lock body 412 is radially movably inserted through the side wall of the top receiving groove 311 and the side wall of the battery top shell 32 and inserted into the side wall of the battery sleeve 14. The second end of each lock body 412 is radially movably arranged in the top receiving groove 311, and the top of each lock body 412 is provided with a bevel groove 4121. The first end of the first elastic body 411 is arranged at the second end of one lock body 412, and the second end of the first elastic body 411 is arranged at the second end of another lock body 412 arranged opposite to the lock body 412.

[0087] In a specific embodiment, Figures 8 to 12 As shown, the upper end surface of the first end of the lock body 412 is a horizontal surface, and the lower end surface thereof is a guide inclined surface 4123 inclined away from the battery assembly 3, which can facilitate the first end of the lock body 412 to be radially movable through the side wall of the top receiving groove 311 and the side wall of the battery top shell 32 and be inserted into the side wall of the battery sleeve 14. In a specific embodiment, as Figures 8 to 11As shown, the locking part 4 also includes a battery unlocking button 42.

The inclined surface of the inclined groove 4121 fits the inclined surface of the inclined block 4211, so that the vertical movement of the button body 421 is linked to the radial movement of the lock body 412. The bottom of the button body 421 is provided with a first accommodating cavity 4212, and the top accommodating groove 311 is provided with a second accommodating cavity 312. The first end of the second elastic body 422 is arranged in the first accommodating cavity 4212, and the second end of the second elastic body 422 is arranged in the second accommodating cavity 312. The elastic force of the second elastic body 422 is smaller than the elastic force of the elastic portion 2 .

[0088] More specifically, when the battery assembly 3 is inserted into the battery sleeve 14, the first ends of the multiple lock bodies 412 of the battery lock buckle 41 radially extend into the side wall of the battery sleeve 14, thereby fixing the battery assembly 3, and the elastic part 2 is in a compressed state. When the battery unlocking button 42 is pressed, the battery unlocking button 42 moves vertically downward, and its inclined block 4211 also moves vertically downward, and the inclined surface of the inclined block 4211 slides along the inclined surface of the inclined surface groove 4121, giving the lock body 412 a radially inward thrust, so that the first ends of the multiple lock bodies 412 of the battery lock buckle 41 are radially retracted and separated from the side wall of the battery sleeve 14, and the elastic part 2 is reset to eject the battery assembly 3 axially.

[0089] Specifically, when the battery assembly 3 is inserted into the interior of the battery sleeve 14, the inclined surfaces of the first ends of the multiple lock bodies 412 are utilized, and the first ends of the multiple lock bodies 412 are first radially retracted to cause the first elastomer 411 to be compressed, and then the first ends of the multiple lock bodies 412 are radially extended out of the side walls of the top accommodating groove 311 and the side walls of the battery top shell 32 and inserted into the corresponding grooves on the side walls of the battery sleeve 14, thereby fixing the battery assembly 3 and the elastic part 2 is in a compressed state. When the top of the button body 421 is pressed, the bottom slopes of the multiple inclined blocks 4211 are driven to slide downward along the slopes of the multiple inclined grooves 4121, thereby driving the first ends of the multiple lock bodies 412 to radially retract (move in the direction away from the side wall of the battery sleeve 14) until the first ends of the multiple lock bodies 412 are separated from the battery sleeve 14, and the elastic part 2 is reset to axially pop out the battery assembly 3, thereby achieving the actual effect that the battery unlocking button 42 can drive the battery lock buckle 41 to unlock, but the battery lock buckle 41 cannot drive the battery unlocking button 42.

[0090] In a specific embodiment, Figure 1 , Figure 7 , Figure 8 , Fig.10 , Fig.11 As shown, the elastic modulus of the second elastic body 422 is smaller than the elastic modulus of the elastic portion 2 , which can prevent the battery unlocking button 42 from being unable to be pressed.
