Problems solved by technology

In 2005, the US FDA approved implantable vagus nerve stimulation as an antidepressant therapy, but it is expensive and has a serious risk of postoperative infection, so it cannot be effectively promoted
[0003] On the one hand, the range of diseases currently guided by ear vagus nerve stimulation therapy is relatively wide, such as epilepsy, diabetes, insomnia, depression, etc., and the pathogenesis of many different diseases is different, but it is obviously unreasonable to choose the same stimulation parameters
On the other hand, the range of stimulation parameters currently available for the treatment of depression is relatively large (1.5Hz-120Hz), and the definition of effective stimulation parameters is vague

Embodiment 1

[0050] 1. Hardware side:

[0051] 1) The ear vagus nerve stimulation system also includes a personal ear point positioning module and an ear vagus nerve stimulator;

[0052] Personal auricular point positioning module: Use 3D technology to scan the patient's ear, capture micron-resolution 3D images of biological tissues, and print to form a patient-specific ear canal model;

[0053] The ear vagus nerve stimulation system is to fix the ear vagus nerve stimulator in the patient's ear canal model by printing the personal auricular point positioning module, wherein the ear vagus nerve stimulator includes an array signal generator; the array signal generator in the present invention consists of several The electrode is constituted, and the diameter of the electrode is 1 cm.

[0054] 2) MCU: the core processor on the hardware side. The function is as follows:

[0055] A. Drive the Bluetooth module to receive data instructions from the user's mobile device, change the pulse mode a...

Abstract

The invention relates to the technical field of a system for treating depression based on 3D printing ear molds. The system comprises a nervus auricularis vagi stimulation system, a mobile equipment module, a hospital PC terminal, a maintenance terminal and a cloud server, wherein the nervus auricularis vagi stimulation system comprises a pulse detecting module, a bluetooth module, a state displaymodule, a power supply module, a DC-DC adjustable voltage-increasing voltage-stabilizing module, a first voltage increasing module, a second voltage increasing module, a third voltage increasing module and a data processing module; and the stimulus frequency is 15-30Hz, the output current is 1-10mA ( 250 omega load impedance), the output power is 0.1-0.3VA ( 250 omega load impedance ), the pulsewidth is 0.2ms + / - 30%, and the treatment course is timed to 20-40min. According to the system for treating depression, provided by the invention, stimulus parameters are set, so that data in brain waves and the depression can be well combined for analysis, and the effect of stimulation for treatment is exerted.

Description

technical field [0001] The invention relates to an ear vagus nerve stimulation system, in particular to a system for treating depression based on 3D printed ear molds. Background technique [0002] At present, the number of people suffering from depression in the world has reached 322 million. The upcoming China Brain Project will also list depression as a key disease for research. In 2005, the US FDA approved implantable vagus nerve stimulation as an antidepressant therapy, but it is expensive and has a serious risk of postoperative infection, so it cannot be effectively promoted. Studies have shown that the concha concha region is the only area on the body surface where the vagus nerve distributes, and the concha concha region has 100% vagus nerve distribution. Compared with other parts of the outer ear, it can activate the vagus nerve more accurately and produce obvious antidepressant effects. At the same time, the distribution area of ​​the vagus nerve is just the key p...
