Figure 1, in General, presents a block diagram of the claimed system.

Utility Model Implementation

The claimed solution, in fact, reveals the model of the so-called smart chamber.

The automated information system of this chamber integrates the available information resources of the clinic and the engineering communications of the patient's chamber, which include: medical information systems of the clinic; system for archiving and storing medical images; food ordering system; ward curtain management system; chamber lighting control system; climate control system of the chamber; Interactive Internet access system; interactive tv.

To ensure the integration of diverse types of information and engineering systems of the clinic, a comprehensive software and hardware solution has been developed that ensures the fulfillment of the entire list of automation tasks, as well as allowing further expansion of the system's functionality by increasing executive elements. The hardware of the patient room includes two personal computers. The first PC is the “Patient Chamber Server” and provides access, visualization and management of automated software and hardware. The second PC provides the user with an intuitive interactive user interface and transfers the actions to the server of the patient’s room.

Media content is transferred to the ward through the local area network (LAN), a specialized set-top box is used to decrypt it. An LCD TV with Internet access is used to visualize media content and as a monitor of a patient’s ward server.

Management of engineering systems is carried out according to the X10 protocol used, in particular, in the development of Smart Home projects. This protocol allows transmitting control commands over a 220 V high-voltage network, which allows laying specialized communications for transmitting control commands. The X10 command translation module provides the conversion of engineering communications control commands transmitted by the patient’s chamber server into X10 protocol commands that are transmitted via a high-voltage network to actuators providing control of a specific device. Network-controlled devices include lighting control devices, curtain control devices, and climate control devices.

The ward provides access to the Local Area Network (LAN) of the clinic, which integrates all the medical information resources available in the clinic, as well as a WiFi network that allows mobile devices to access the network.

The main software of the information system of the patient’s room is the software Visual Desktop Control (VDC) developed as part of the project. VDC software consists of two interconnected components: the VDC WCF Service and the VDC User Interface. To manage engineering communications, an ECM11 interface module control driver was developed, and a reader control driver, in particular, smart cards, was developed to provide a process for authorizing users in information systems.

The management service of the server of the patient’s room is an executive element and implements the control logic of various technological processes, as well as the function of executing the actions of virtual controls. The service is implemented using the Windows Communication Foundation (WCF) technology. The service uses the TCP protocol as a data exchange protocol, which allows increasing the speed of data exchange between the service and client applications. Specialized drivers have been developed to control peripheral devices, a smart card reader, and a module for translating control commands into the X10 protocol. The server management service interacts with the drivers, sending commands received from the client for execution, and also intercepts events of changes in driver states.

The graphical user interface provides users with a virtual graphical interface implemented using the Windows Presentation Foundation (WPF) technology. To interact with the server management service, the graphical user interface interacts with the WCF client, which transfers control commands to the server for subsequent execution.

The developed system allows you to access the medical information system (MIS) to the extent that the rights granted to the user provide. Differentiation of access rights occurs at the user level provided by the developers of the information system. In order to ensure the protection of information, as part of the project, an authorization algorithm was developed using RFID tags, radio frequency or infrared tags, a barcode or personalized smart cards.

In this case, an example of authorization using smart cards is given, when for authorization the user does not need to enter a username and password, just insert a personal card into the smart card reader. In this case, the server management service automatically determines the presence of a card in the reader, reads the personal user code from a smart card. Next, the MIS database is accessed to verify user rights. If user rights allow authorization in the MIS, it automatically starts and authorizes. If the user is not granted the right to use the MIS, the presence of the card in the reader will be ignored by the system. The medical information system operates in authorized mode only if the user card is in the smart card reader. If the card is removed from the reader, the server management service automatically intercepts this event and closes all connections to the medical information system.

When a user works with a medical information system using a tablet PC, the server will process and transmit events of cursor movement and keystrokes of the keyboard of the tablet’s virtual user interface to the MIS graphical user interface. Thus, for full-fledged work with MIS, the user does not need the presence of a hardware keyboard connected to the server and a hardware mouse.

Management of engineering communications is carried out by the server of the patient's chamber. The server receives control commands from the tablet. Each command contains an operation code and an executive device code, the patient chamber server management service transmits them to the ECM11 control module driver. Then, the ECM 11 transmits the commands to the X10 protocol and transfers them to the actuators via a high-voltage network.
