Digital and integrated hospital operating room is the integration, upgrading, expansion and mining of facilities and functions of common laminar flow operating room on the basis of hospital digital construction. By using the information network platform built by hospital digital construction, the operating room and the information network inside and outside the hospital are integrated, the operating room equipment and facilities and the overall function of the hospital are improved To a new level, it can not only provide a good operating environment for patients, but also provide perfect conditions for innovation, communication and development of surgery and minimally invasive surgery, and promote the improvement of professional technology level.
So, how to build a digital and integrated operating room? It is generally divided into two stages: design and construction. The details are as follows:
design phase
1. Determine the objectives and build a signal management platform

In the stage of hospital design, the goal of constructing digital and information operating room is established. In order to integrate all signals into the digital system of the operating room, the brand models and signal output interface types of the common medical equipment in the operating room are analyzed. In many hospital investigations, it is found that anesthesiologists hope that ECG monitoring signals can be shared to provide judgment basis for surgeons; chief surgeons or deputy surgeons hope to get PACS Image Information; internship assistants hope to get real-time endoscopic image, surgical field image and other learning information. In order to meet the needs of everyone, it is necessary to build a signal management platform in the operating room.
2. Adjust measures to local conditions and arrange operating room reasonably
The graphic design of operating room is also closely related to the construction of digital and information system. The positioning of the operating room shadowless lamp and the surgical suspension tower involves the layout of the suspension bracket and the suspension display. For the orthopedic operating room and other rooms that need to use C-arm machine, we can use a separate set of parent-child shadowless lamp and a display spring arm at the same time. For rooms without special requirements, use the center mounted child and mother shadowless lamp with display spring arm, reserve the video signal line used by the monitor on the anesthesia suspension tower, and reserve the video signal line used by the cavity mirror on the surgery and cavity mirror suspension tower.
3. Meet the requirements and install the information display terminal
As the terminal carrier of CIS access and equipment signal, the information display terminal installed on the surgical wall bears multiple functional requirements. Therefore, in the operating room, we should use a variety of types to meet the size of different operating rooms and the needs of different types of operating rooms.
4. One for use and one for standby, laying signal source cable
In the early stage of operating room construction, it is necessary to reserve all signal cables and consider the possibility of cable repair and replacement. The position of the signal output terminal shall be determined according to the position of the reserved cables in the early stage, and all cables shall be collected to the information display terminal or the integrated cabinet to realize the signal playback. In addition, the signal cable maintenance in operating room and the development of follow-up medical equipment should also be considered. The signal source cable of medical equipment should adopt the layout principle of "one for use and one for standby", and four category 6 network cables should be reserved for the expansion and upgrading of equipment in the future.
Construction management stage
1. Embedded digital equipment
In the construction phase of the project, in order to meet the environmental control requirements of the operating room, all digital equipment needs to be embedded in the wall for installation. Therefore, it is recommended to use the way that the front panel can be opened, and reserve the box at the back as the installation space for the display screen, system host, video distributor and cable. This design can eliminate the problem that CIS computer host must be placed in the operating room, and make the net use area of the operating room increase effectively. At the same time, infrared scanning gun and signal input interface can be set on the front panel, which not only reduces the floor space of the equipment, but also hides all the cables, so that the sterile environment control in the operating room has a new level. The color of the information display screen shall be the same as that of the wall panel, and the overall dimension shall be customized from the manufacturer according to the module of the wall panel in the operating room, so as to ensure the beauty and facilitate the later upgrading.
2. Set up information display terminal

The positioning of the information display terminal also needs to be combined with the actual use of the operating room. As a terminal to access CIS and equipment signals, it needs to meet the double considerations of CIS operation input of itinerant nurses and the convenience of chief scalpel doctors to obtain medical equipment information at the same time. The information terminal is set on the opposite wall of chief scalpel doctors, and the 24 "display is closer to the work scope of patrol nurses and the comprehensive information panel area of operating room, both of which are used. At the same time, physical keys are set on the panel of information display terminal to facilitate one key switching of equipment signal source.
3. Add signal distributor
For 55 "display, if it needs to support 4K resolution ultra-high definition, it can display 4 channels of signals to medical workers on the screen at the same time. Therefore, a signal distributor can be installed at the back end to support 4 split screen display. At most one operating room is equipped with 19 signal cables of different models to connect all operating room equipment output images in series. During the installation of frequency divider, a series of compatibility problems such as signal output type, resolution, refresh rate, etc. of different equipment manufacturers need to be solved.
Digital and integrated operating room can improve the utilization rate and work efficiency of equipment; optimize the working process and reduce the operation cost; improve the quality of medical service; enhance academic exchanges and cooperation, strengthen the construction of talent team; provide network value-added services, create the hospital brand; improve the level of hospital management, which is a new model of modern hospital operating room construction, and also the necessity of future operating room development The trend.
