Centralized control, test and diagnosis of medical equipment in digital operating room based on Hongke PCA interface card
Digital operating room is the product of the development of computer information technology, biomedical engineering technology and modern medical technology. Using the digital port transformation of the existing equipment in the operating room, through digital network integration, the centralized control workstation controls the intraoperative medical equipment, and interacts with the network information inside and outside the hospital in real time. The schematic diagram of digital operating room is shown in the figure below.
Challenge
Problems faced by digital operating room
1. The number of medical equipment is large, and centralized control is difficult
In the existing operating room, there are many kinds of medical equipment, and the control panels of various equipment are quite different. Moreover, most of various operating room equipment are independent units, and there is no external unified communication interface, which brings compatibility problems. Secondly, the communication quality of centralized control is also directly related to the safety and efficiency of surgery. The communication between centralized control workstation and controlled equipment must be real-time, accurate and stable. To sum up, the centralized control of digital operating room is difficult.
2. Medical equipment is precise and expensive, and the maintenance cost is high
Medical equipment is complex and expensive. In case of communication failure, the equipment is generally replaced or waiting for professional maintenance. The corresponding failure causes are often unclear and the maintenance methods are not systematic, resulting in high maintenance time cost, high maintenance cost, resource waste and other problems. Therefore, it is necessary to introduce a set of effective medical equipment testing and diagnosis scheme.

Centralized control, test and diagnosis of medical equipment in digital operating room based on Hongke PCA interface card
1. Centralized control
In order to realize the centralized control with high compatibility and security, can bus is selected as the communication protocol between equipment and equipment in the digital operating room and between equipment and main control. This requires the transformation of the digital port of the existing equipment in the operating room and the introduction of can interface, while the PCA interface card plays the role of "reformer". Its schematic diagram is shown in the figure below. PCAN can connect with medical devices through a variety of different interface types, such as USB, PCI, PCIe, minipcie, m.2, RS232, etc., quickly introduce standard can interface for medical devices and connect to can bus network. At the same time, the secondary development package provided by PCAN interface card can help developers flexibly realize the sending and receiving of can data, which is stable and reliable.
2. Test and diagnosis
Since the CAN bus structure is adopted to realize the construction of digital operating room, that is, the bottom sensors and actuators, medical equipment nodes and main control terminals are connected through can communication to realize information sharing and comprehensive management, a set of test and diagnosis system can also be developed for CAN bus, as shown in the figure below. The test and diagnosis system is based on PC and PCA, From bottom to top, it is composed of hardware, driver, software and application. Connected to the can network of the digital operating room through the can cable, the data of all nodes can be collected, and through data analysis and fault judgment, the current operation status of all medical equipment can be displayed intuitively, and the excitation signal can also be injected into any equipment node for function and stability test. As a can access point, PCA not only realizes the bottom can data transmission and collection, but also has the can fault prompt function. It is the bottom basic hardware to realize test and diagnosis. In particular, PCA can also enter the single listening mode to monitor the operation of the equipment as a listener, which will not have any impact on the can network, and can find and record intermittent faults in real time.
