Chapter 1: Demand Analysis
In recent years, IT investment in the medical and health industry has increased significantly. The management level in the medical and health field in my country has made considerable progress, and the basic medical information system has been continuously improved. Most of the domestic top three hospitals have adopted HIS and PCS hospital information management systems to realize the management of basic medical data.
However, the hospital is an extremely dynamic working environment, and medical resources and personnel are changing in real time and need to be dealt with in a timely manner. For example, you need to know where the nearest clean infusion pump is during first aid, and you need to find a doctor as soon as possible; you need to know the patient when taking medicine. The lack of such real-time information often leads to delays in treatment and mistreatment, which affects the quality of medical services.
A medical institution that lacks high-resolution asset and personnel monitoring can cause the following problems:
1. Equipment loss. Every year, portable equipment usually loses nearly 20% due to misplacement, theft and other reasons.
2. Manpower waste: material supply and management, nurses, clinicians, every day need to spend a lot of energy to find
3. Patient services are delayed, and the required doctors or equipment cannot be found in time, which delays the rescue time of the injured
4. Low service quality: unable to obtain the patient’s diagnosis and treatment information and asset administrative management information in time, resulting in low efficiency, counterfeit drugs, etc.
5. Low asset utilization rate: the inability to quickly find suitable equipment causes the hospital to stock too many similar materials or lease additional equipment, and most of them are either idle or inefficient in utilization
6. Expired use of equipment: Due to lack of management and preventive maintenance measures for some equipment are not timely, they are at risk of expired use or overuse.
In summary, it can be seen that the lack of real-time monitoring of medical assets and personnel directly affects the quality of diagnosis and treatment services and hospital benefits. Hospitals urgently need to establish a medical dynamic management platform to realize automatic real-time tracking of medical resources such as medical equipment, wards, patients, patient safety, medicines, medical waste, and medical supplies, and build a new generation of medical emergency systems and society based on this. Emergency medical defense system.
Chapter 2: Hewei RFID Medical Information Application System
He is the RFID medical information application system, which realizes the perfect combination of RFID technology, wireless network technology, PDA mobile phone and hospital. Realize real-time tracking and integration of various medical resources such as medical equipment, patients, doctors, etc., so as to reduce the work intensity of medical staff, improve the work efficiency of medical staff, effectively prevent medical accidents caused by operating errors, and increase the utilization rate of medical equipment , Save medical costs and increase safety and other benefits. Push the medical management model to wireless, mobile, and intelligent.
As shown in Figure 1, the main working principle of the system is to use the RFID electronic tag as an identification code and associate it with the controlled target, so as to realize the tracking, positioning and management of the target. RFID electronic tags (wristbands, signs, suction cups, etc.) are attached to the objects, equipment, and personnel to be controlled. The wireless signal sent by the tag in real time is recorded by the radio frequency signal analyzer and sent to the real-time positioning server through the switch. The server uses a patented algorithm to calculate the two-dimensional (three-dimensional) coordinates of the controlled target and sends it to the three-dimensional virtual hospital simulation platform. The simulation platform displays the location and trajectory of assets and personnel in real time, and completes a variety of application functions through integration with HIS, video surveillance and other systems.

Hewei RFID medical information application system mainly implements the following applications:
Figure 2 He is the main application of RFID medical information application system
1 3D virtual hospital
Constructing a virtual hospital with 3D simulation technology makes visual medical management possible.
The 3D virtual hospital simulation platform is based on a 3D graphics engine to visually display 3D virtual images of the prison’s internal environment, buildings, floor structures, pipelines, facilities, equipment, patients, and medical staff. It can be used for 3D simulation, information integration, and Real-time location monitoring, video linkage, and alarm reminders are the core integration platform for the automation of the entire site.
2 Real-time positioning of personnel assets
Use radio frequency identification technology to realize real-time location monitoring of medical equipment, doctors, nurses, patients, etc. Based on real-time location information, it realizes access control security management, medical equipment positioning tracking, patient flow management, patient safety management, staff identification and medical staff positioning, etc.
And for the real-time positioning of personnel assets can provide real-time location information of medical staff, medical equipment, etc., so as to find the required objects in real time, avoiding delays in the treatment time of patients; it can automatically search and locate and manage special patients, such as infectious disease patients, High-risk patients, mental patients, etc., to quickly find targets in any corner of the hospital to prevent the spread of infectious diseases and other malignant accidents; it can quickly locate and find medical equipment that must be regularly scheduled for preventive maintenance and prevent medical treatment. Unnecessary tragedies caused by equipment problems occurred. At the same time, through the graphical interface of the background 3D virtual hospital simulation platform, the staff can conveniently monitor and manage the controlled valuable assets and personnel in real time.
Based on patented positioning technology, Hewei RFID real-time positioning system realizes accurate positioning and tracking of assets and personnel in the wireless network coverage area. The implementation of this system accurately and effectively locates, manages and deploys equipment and personnel in the hospital, enhances the visibility of assets, and achieves maximum utilization and return on investment.
