Project Management

Economics

As of 2016, TMS treatment sessions range from $200 to $300 each². Because each session typically needs to be done several times a week for at least 4-6 weeks, a full round of TMS treatment can eventually cost the patient $5000-$10,000, depending on insurance and other details. Aiming to reduce this cost, we believe that paying a one-time fee for a device that can be used throughout the TMS treatment is beneficial to the consumer. Currently, the bulk of the project costs are due to the software simulations and circuit design process. The Multisim simulation software license has been provided by the University of California, San Diego. Apart from the license, the main cost has been worker-hours. Looking towards the future and the potential construction of a working at-home TMS device, manufacturing costs depend on material quality as well as specific material properties for the housing unit. One such material property involves the ability to efficiently dissipate heat. Moving forward we seek to continue the optimization of a TMS device and hope to see this translate into a more cost-effective solution for patients.

Environmental and Safety

Multisim is strictly a simulation software and therefore has no current environmental impacts. At this stage, no materials or devices were built that could impact the environment and as a result, these factors have not been considered. Further stages for an at home TMS device however could pose environmental impacts since a large device requires a large amount of energy and materials. A battery powered device would require the proper disposal of the battery as well as environmental friendly material to construct all aspects of the machine. Overall, this project possesses minimal concern for the environment.

Safety continues to be the largest concern in constructing this device. Current TMS machines operate at a maximum of 5000 amperes, although the procedure is conducted in a safe environment. Our reduced power device still operates at about 250 amperes, much above the fatal level. Any faulty wiring or possible exposure could is an primary safety concern and must be addressed. The appropriate safety concerns should be addressed in both circuitry and overall device design. In addition, the eventual device must be user friendly to prevent a misuse in the device. Restrictions may be implemented to ensure the device is located on the correct head location, used at appropriate times, and can easily be controlled by the user. These met safety precautions will guarantee a fully functional at home TMS device.
