Transcranial Magnetic Stimulation (TMS) is a non-invasive method used to stimulate nerve cells in the brain. This technique uses magnetic fields to induce weak electrical currents in specific regions of the brain. TMS is particularly used for treating psychiatric disorders such as treatment-resistant depression, anxiety, Parkinson’s disease, and neurological conditions such as migraines and chronic pain. During a TMS session, a magnetic coil is placed on the scalp near the targeted brain area. The electrical current passing through the coil generates magnetic fields that penetrate the brain and stimulate neurons. This stimulation can modify neural activity and help correct abnormal brain functions.
TMS offers many advantages due to its non-invasive nature and the fact that it does not require surgery or psychotropic drugs. It is often used as an alternative or complementary treatment for patients who do not respond to conventional therapies.
In the industrial design of a Transcranial Magnetic Stimulation (TMS) device, with a high requirement for serviceability, attention to several key aspects is essential to ensure not only optimal performance but also comfort and safety.
The use of appropriate manufacturing methods is one of the first considerations. For limited production, the use of 3D modeling, rapid prototyping, and sheet metal fabrication can help accelerate the design and evaluation process. Regarding serviceability and component separation, the design should allow for easy maintenance and repair. This includes the use of modular connections, screws, and standard fasteners that enable simple replacement and servicing of various components. In addition, the design should ensure that parts can be easily detached and replaced to minimize maintenance time and cost.
Reducing the device weight compared to previous models is also highly important. To achieve this, the use of lightweight and durable materials such as reinforced plastics or thin but structurally optimized metal sheets is recommended. These materials help reduce the overall weight without compromising strength and durability. Furthermore, the design may include hollow structures or other lightweight engineering approaches to reduce total device mass. Ease of transportation must also be carefully considered. The device should be designed with ergonomic handles or wheels for easy movement. Its dimensions and weight should allow for convenient transportation and handling by users.
To protect high-voltage components, the design must include safety covers and protective enclosures that minimize access to these areas and prevent accidental contact with hazardous parts. This significantly enhances device safety and reduces potential risks.
Finally, the device monitor or display should be designed with adjustable angle capability so that users can easily view device status and settings. The adjustment mechanisms should be easy to operate and stable, ensuring that the monitor remains securely positioned during use and provides an optimal viewing experience for the operator. With these features, the TMS device can effectively and safely perform its function while delivering an optimal user experience for both patients and medical staff.
