use the system. The functional software at this layer needs to
provide requirements to the service management layer, and
then form a more complete and accurate requirement for the
platform as a service layer for development, and support the
isolation of different user data and related configurations to
ensure the security and privacy of medical data.
2) Service Management Layer
This layer is the core part of the medical cloud IoT and the
foundation of the medical service layer. It ensures that the
entire medical information system can operate safely and
stably, and provides functions and technologies in mainte-
nance, multiple management, and other aspects. This layer
can play a good role in communicating with users, fully
understand and analyze user needs, which is conducive to the
medical platform as a service layer to avoid or eliminate early
errors early, thereby improving the efficiency and quality
of software development and reducing development costs.
At the same time, this layer can also collect and screen
all software in the medical platform as a service layer, and
publish the screened software in the medical software as a
service layer.
3) User Layer
Users at this level refer to users of medical information
sharing systems, including medical institutions at different
levels, disease control centers, community clinics, and so
on. Users can access the user layer through the interface
of mobile phones, computers, and other terminal devices,
and will become a member of the cloud after access. While
enjoying the services provided by cloud computing, users can
also transmit their own resources to the cloud for other users
to use, to realize real data sharing and resource sharing. For
doctors, access to the cloud network can track and obtain
patient information, treatment plans, treatment details, etc.
in real-time, while patients can choose any medical institu-
tion for treatment according to their own conditions through
the cloud network. More importantly, experts from different
medical institutions can conduct collaborative consultation
for severe patients or difficult and miscellaneous diseases
through a cloud network, which greatly improves the pos-
sibility of curing patients and solving medical problems.
