Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to a magnetic shock therapeutic apparatus. Background Art

[0002] Magnetic seizure therapy (MST) is a treatment method that uses a repetitive transcranial magnetic stimulation (rTMS) device and coil to generate a series of magnetic pulses of a certain intensity while the patient is under general anesthesia to induce convulsive seizures. Compared with electroconvulsive therapy (ECT), MST has a shorter duration of epileptic seizures, lower EEG amplitude during the seizure, and less post-ictal inhibition, so there are fewer subjective side effects and a faster recovery direction.

[0003] Existing MST devices have greater power requirements than standard rTMS devices. In order to meet the high power requirements of MST devices, companies such as MagStim and MagVenture use multiple rTMS devices stacked together to build MST treatment devices. However, the stacking of multiple standard rTMS devices will greatly increase the cost of MST devices. On the other hand, due to the large power output of MST devices, the heat generated by the devices is often very concentrated, resulting in very high heat generation of the host, especially the magnetic stimulation coil. When in use, the MST device generally outputs continuously for 10 seconds or 8 seconds, and then needs to be shut down for more than half an hour to cool down, resulting in low treatment efficiency.

[0033] Please refer to Figure 1An embodiment of the present invention provides a magnetic shock therapy apparatus, which specifically includes a host 1 and N magnetic pulse coil modules 2 electrically connected to the host 1, wherein N is a non-zero natural number.

The magnetic field control module 11 is connected to each magnetic pulse coil module 2, and is used to drive the magnetic pulse coil module 2 to generate a corresponding alternating pulse magnetic field according to a set magnetic field mode.

[0035] It should be noted that the magnetic field control module 11 can be used to generate a driving current with a specific timing and frequency according to the set magnetic field mode, so as to cooperate with the magnetic pulse coil module 2 to generate an alternating pulse magnetic field with a frequency of 0 to 100 Hz and an intensity of 0 to 4 T, thereby effectively stimulating the user's convulsion attack.

[0036] The temperature control module 13 is used to control the temperature values ​​of the host 1 and the N magnetic pulse coil modules 2 within a set temperature range.

[0037] It should be noted that, in this embodiment, the set temperature range is specifically 15 degrees Celsius to 45 degrees Celsius.
