Chapter 1 Intelligent System Requirements Analysis

Intelligent system is an indispensable and important system under the digital hospital platform, playing a role in bearing, maintenance and support, the deepening design of the weak current system of the smart hospital is an important part of the construction of the intelligent system, the design and construction of the intelligent system must stand on the large platform of the digital hospital to consider, to meet the requirements of digital applications, the future development needs of a digital hospital, so that the weak current system can truly provide support for the development of the smart hospital in the direction of the digital hospital.

1.1 Peculiarities of hospitals

The reason why hospital buildings are different from ordinary buildings can be analyzed from three aspects: the diversity of modern hospital building functions, the easy pollution of the hospital environment, and the particularity of the human environment, which is also the basic starting point for the construction of intelligent hospital information system.

Differences in personnel needs:

Patients with l disease need a comfortable medical and living environment;

l Medical and medical technicians need a good working environment;

Managers need an efficient management environment.

Differences in business needs:

l Medical clinical information, clinical experience, clinical decision support;

l Monitoring of the operation of medical facilities and equipment;

l Medical management information, management experience, management decision support.

Equipment, facilities and instruments have different needs:

l Wide range of information collection and many types of information collection;

l Monitoring of ambient air quality and medical gas;

Grounding protection and electromagnetic shielding of medical instruments;

l Automatic control of pneumatic pipeline transmission of medical supplies;

l Information system support for clinical business.

1.1.1 Diversity of building functions

Hospital buildings are a special architectural group that distinguishes them from other buildings due to their medical particularity. In addition to general facilities/equipment, there are also a large number of sophisticated medical instruments and medical equipment in the hospital building. The main function of the hospital is to treat the sick and save lives, and at the same time shoulder the responsibility of teaching and scientific research. Therefore, the hospital is a place where information, knowledge and high technology are highly distributed. In view of this particularity, we fully consider the development trend of medical examination instrumentation, medical process informatization and medical information integration of modern medicine, and build a systematic and comprehensive platform for this development.

1.1.2 Pollution of the environment

A hospital is a place where people flow around with a wide range of patients, and a large number of biological and chemical reagents, as well as radioactive equipment and materials, are stored and used in the hospital. Therefore, the hospital is also a biological, chemical, radioactive prone area of contamination. Therefore, the intelligent system of environmental monitoring should fully take into account the above factors in the planning and design, and should take intelligent monitoring and other means to block the transmission of various pollution routes in view of the flow of various groups of people in the hospital building, the exchange of air, and the isolation of polluted areas and clean areas. Therefore, in addition to ensuring that patients are provided with qualified medical services, modern hospitals must also provide a safe medical environment and working environment for patients, medical staff, and management personnel.

1.1.3 The particularity of the human environment

A modern hospital is a social environment composed of patients, medical staff, administrators, and patients' families. Modern hospitals operate 24 hours a day, and some patients seek medical treatment and live in hospitals for a long time, and hospitals are also one of the environments they rely on to survive; and the social composition of patients is complex, religious beliefs and living habits are very different, and the needs of the hospital environment are also different. At the same time, the hospital is also an environment where all medical staff work for a long time and some medical staff live.

In the current social environment of advocating "people-oriented", how to fully embody the service concept of "humanistic medical care", "humanistic service" and "humanistic environment" of modern hospitals, in order to realize a comfortable medical environment for patients, a good working environment for medical staff and an efficient business environment for managers, this is the main issue to be solved by the intelligent hospital information system.
