Description
Technical Field
[0001] This application relates to the field of medical device technology, and more particularly to a digital operating room. Background Technology
[0002] Digitalization is the future direction of hospital development. A digital operating room refers to the application of modern technology to the operating room environment, utilizing hardware and software facilities to establish a complete operating room information data system. A digital operating room perfectly integrates purification engineering with digital information technology, systematically integrating all patient information in the best way. This allows surgical staff to obtain comprehensive patient information, more imaging support, precise surgical navigation, and smooth external communication, providing a more accurate, safer, and more efficient working environment for the entire surgery. It also provides a reliable channel for surgical observation, surgical teaching, remote teaching, and remote consultation, thereby creating a high success rate, high efficiency, high safety in the operating room and enhancing external communication.

Sequential power supplies usually only support 220V AC, and devices with other voltage requirements need to use OEM adapters or external voltage conversion devices. Both of these methods require multiple OEM adapters and voltage conversion devices, resulting in complex wiring and difficulty in maintenance. Utility Model Content

The first conversion module 12 includes an AC / DC conversion module that converts AC power into DC power. For example, the second power source is 12V DC power. This application does not limit the conversion method of the first conversion module 12, such as a transformer conversion method or a switch conversion method.

The first output terminal 17 is an AC output interface, and the second power input terminal 18 is a DC input interface. The AC output interface and DC input interface are electrically connected to the AC / DC module of the peripheral device. The AC / DC module converts 220V AC power to 12V DC power and re-inputs the 12V DC power into the power management unit 1. The DC input interface is electrically connected to the second conversion module 13 (i.e., the DC / DC module) and the first output interface 14 inside the power management unit 1. The DC / DC module converts the 12V DC power to 5V DC power (or 3.3V DC power). The DC / DC module is electrically connected to the second output interface 15. The first output interface 14 is used to power devices requiring 12V DC power, such as video processors, fans, fiber optic transceivers, and power indicator lights. The second output interface 15 is used to power devices requiring 5V DC power, such as controllers.
