Objective To explore ways to interconnect the host with small medical instruments so that the network of small medical instruments can be finally realized. Methods This article proposes the use of Universal Serial Bus (USB) to achieve the interconnection of the host and the small medical instrument, and also solves the most critical technology in this program, that is, how to use the USB bus to achieve real-time data acquisition and transmission of medical signals. Work includes hardware design, firmware design, driver design, and application design. As a result, real-time data acquisition and transmission of medical signals was realized using USB bus, laying the foundation for the next step in achieving the interconnection of medical instruments and hosts. Conclusion It is feasible to use universal serial bus to interconnect the host with small medical instruments.
