1 Background and current situation
1.1 BackgroundSince 2009, the State and the Ministry of Health have successively issued "Opinions on Deepening the Reform of the Medical and Health System", "Implementation Plan for Deepening the Reform of the Medical and Health System from 2009 to 2011", "Program for the Construction of a Regional Health Information Platform Based on Health Archives", "Consultation Draft for Electronic Medical Record Standards" solicited and "Electronic Medical Record-based Hospital Information System Construction Plan" and other documents; proposed to establish a practical and shared medical and health information system to promote public health, medical treatment, medical insurance, drugs, financial supervision Informatization construction is the focus, integrating resources, strengthening information standardization and the construction of public service information platforms, and gradually achieving uniformity, efficiency, and interconnection. The construction of medical and health information is an important means and technical support for deepening the reform of the medical and health system, building a service-oriented government, and promoting the healthy development of the medical and health undertakings. In the next three years, governments at all levels are expected to invest 850 billion yuan to implement medical reforms, which is a market with great potential.
According to the requirements of the Ministry of Health, medical institutions and their management units at all levels should gradually establish a patient-centric electronic medical record system and a regionalized electronic health record system to meet people ’s various needs for personal health information. At the same time, The above-mentioned information systems are widely and highly interconnected.
1.2 Status
1.2.1 From paper medical records to electronic medical records
At the beginning and development stage of medical system informatization, each medical institution has basically established independent medical information systems such as HIS, LIS, and PACS for charge management. For medical records, paper-based, hand-written traditional medical records are still used, as shown in the following figure:
Figure 1 One page of paper medical records Figure 2 Medical records bound into volumes
Entering the development of medical informatization today, in order to effectively realize the demand of "clinical information exchange and sharing" in medical institutions, it is urgent to establish a perfect electronic medical record and electronic health file system.

1.2.2 Existing medical records electronic methods
For information such as observation records, consultation records, medical orders, etc. that need to be recorded in real time for patient characteristics, most current electronic methods first form handwritten paper records, and then:
1) Real-time keyboard entry
Disadvantages: increase the work intensity of personnel, and errors are easily generated in the input process;
2) Focus on keyboard entry
Disadvantages: increase personnel costs, unable to achieve real-time and strict medical records;
3) Scanning entry
Disadvantages: increase the workload of personnel, information cannot be structured, resulting in information cannot be queried and counted;
4) Existing tablet input
Disadvantages: not intuitive, poor human-computer interaction.
2 Brief introduction of MCA application program of EVOC terminal
In order to solve the above problems and make the electronic medical record complete in one go, we have launched the EVOC terminal MCA for EHR and EMR systems.
2.1 MCA application block diagram of EVOC terminal
In response to the current status of electronic medical records in China, a doctor workstation platform product dedicated to electronic medical records systems has been developed. The block diagram of this application is shown below.

2.2 MCA main functions
1) Innovative handwriting input function
Historically, due to the large amount of information and the complexity of the types of information entered, the informationization of the medical system has also caused the doctors ’own medical workload to be very large, which has made doctors disagree about the entry of medical records and personal health information.
The innovative handwriting input function provided by EVOC terminal MCA has the following advantages:
User-friendly: computer handwriting is the same as traditional paper handwriting; small learning curve, no need to learn the keyboard, word splitting or pinyin required for traditional keyboard entry; high efficiency and high recognition rate with the help of computer-assisted technology; handwriting retention , Which is never achieved by keyboard input; the real characteristics of the large data input and handwriting retention requirements that are truly suitable for electronic medical record systems;2) One machine with multiple functions
EVOC terminal MCA provides multiple functions such as RFID, 1D / 2D barcode scanning, video, screen rotation, and mobility.
2.3 Main characteristics of MCA
1) Powerful handwriting input function
Handwritten content can be saved as authentic and standard words at the same time; full-screen handwriting recognition; medical order input is humanized, in line with handwriting habits;
2) Information security technology: using the most secure CA certificate technology.
4) High safety: The front panel adopts IP54 protection grade, which is convenient for disinfection; light and anti-drop.
5) Using 10-inch high-brightness LED light-emitting screen, lower power consumption, longer life and better effect.
6) Multi-communication connection function: built-in rich medical field application equipment to meet the interconnection and interconnection of multiple medical equipment.
7) Rich interfaces: 1 USB, 1 COM (232/485), 1 power interface.
8) Hot-plugging of dual battery packs.
3 Examples of MCA application solutions for EVOC terminals
3.1 Application in large hospitals and various information systems and EHR, EMR
The following diagram is the application scheme of EVOC terminal MCA in various information systems and EHR and EMR of a large hospital:

3.2 Application in the community medical system
The MOM message middleware technology is adopted, so that each HIS, LIS, PACS manufacturer can seamlessly integrate the existing system with the digital terminal at a minimum cost, saving costs.
The following is the integration of a community medical system with EMR and EHR systems:
