With the rapid development of hospitals, the demand for medical equipment in hospitals is increasing. Modern medical equipment has become a medical equipmentIt is an important symbol of hospital modernization and a powerful means for major hospitals to participate in market competition. In order to improve the medical level and market competitiveness, more and more high-quality, precision and advanced medical equipment have been put into use, which has continuously promoted the development of advanced medical technology.However, the use of high-end medical equipment also brings new challenges to doctors due to complex operation. In the use of equipment, doctors often need the technical personnel of the equipment manufacturer to give operation guidance. Moreover, the manufacturer may have to send technical personnel to the hospital site for equipment update and maintenance, which will not only consume a lot of time and labor cost, but also affect the normal use of the hospital and delay the timely treatment of patients.

Facing the needs of real-time operation guidance and efficient operation and maintenance of medical equipment, aiming at the hospital private network environment and domestic well-known remote control brand sunflower, a physical layer remote control solution - control A2 is given.

The deployment of control A2 is simple and easy to use. Just connect the power supply to the control, connect one end of the USB data cable provided by the control to the control usb-b interface, and the other end to the medical equipment (virtual mouse and keyboard function), connect the HDMI adapter line to the control and medical equipment (output the master image of the controlled equipment), and then connect it to the control A2 through the hospital external network special line or 4G network card, After the medical equipment end is ready, the manufacturer's technicians only need to install the sunflower remote control software and remotely connect the control through the functions of [desktop control], [camera], [SSH] to realize the efficient remote operation and maintenance and operation guidance of the medical equipment.

Flexible Internet access, not limited by the hospital's private networkSunflower control A2 supports three networking modes: wired, WiFi and 4G network card, which does not change the network environment of medical equipment. Whether it is connected to the network cable or connected to the Internet through WiFi or network card, it is control A2 that receives the network signal, which is independent of the medical equipment network and gets rid of the problem of limited hospital network.Plug and play, the hospital controls the use right

As a pure hardware external remote control tool, control A2 is small and exquisite, plug and play. If doctors need operation and maintenance troubleshooting in case of operation problems or equipment faults, they only need to connect control A2 to the medical equipment and notify the manufacturer's technicians for remote connection. After use, the hospital can unplug the control in time. The whole process is led by the hospital to ensure the safety of medical information.High compatibility, not limited by equipment systemControl A2 is the physical layer link of intelligent hardware. It does not need to install any software and is compatible with a variety of operating systems. No matter what operating system is used for medical equipment, it is not limited by the system and can quickly realize intelligent remote control.

With camera and whiteboard, remote guidance is more convenientThe USB interface of control A2 supports an external camera. In the remote operation guidance, the camera can help the technicians of the equipment manufacturer understand the operation details of the doctor in real time and help the technicians better carry out remote guidance; In particular, with the sunflower remote control software, the "whiteboard" function can be opened in the remote control, and the operation demonstration can be carried out through the whiteboard, so that technicians can solve the operation problems more conveniently and intuitively when guiding doctors to operate the equipment remotely.Cross platform use, mobile phone / tablet / PC remote operation anytime, anywhere

Sunflower supports flexible login on mobile phones, iPads, PCs and other platforms. No matter where the technicians are, they can quickly log in to the sunflower control terminal through their portable devices as long as they have a network, so as to provide doctors with remote operation guidance and equipment operation and maintenance in real time.It is worth mentioning that the sunflower data transmission adopts AES / RSA 256 bit asymmetric algorithm encryption and double authentication of user information, which realizes the encryption protection of user information and session, and comprehensively ensures the information security of the hospital.Through the sunflower control A2 solution, medical equipment manufacturers have perfectly solved the problems of remote operation and maintenance and operation guidance of medical equipment. Control A2 is simple and easy to use, with low cost, greatly saving operation and maintenance cost, and the deployment is flexible and highly controllable, meeting the strict requirements of the hospital for safety problems and realizing mutual benefit and win-win.

Moreover, as a powerful physical layer remote control hardware, sunflower control A2 has been successfully practiced in the fields of remote consultation, remote operation live broadcast, remote operation and maintenance of medical information management system, and provides a simple, easy-to-use, safe and reliable low-cost solution for telemedicine.About sunflower remote control

Power supply standardIEC 60601-1:2005 and accompanying documents specify the safety and basic functional requirements of the power supply. The standard appears in the form of ANSI / AAMI document in the United States and in the form of "euronorm" in Europe and around the world, with some local differences. Since January 2021, the latest revision (a1:2012, a2:2020) has updated the standard, deleted outdated references, corrected errors and made it better consistent with IEC 62368-1. The current medical EMC standard IEC 60601-2 is the 4th Edition.Built in medical power standard

AC powered medical devices can have "built-in" power supplies or lower power external adapters. If it is an internal product, the product designer should consider high voltage and high energy, and usually choose to buy a "medically certified" power supply. However, the final product is the product certified for this application, so there are other considerations, such as labels, connectors, internal wiring of power supply and fuses.

Due to grounding, external wiring and interference from other noise sources, the built-in power supply conforming to EMC standards cannot be guaranteed to pass the test. A common practice is to add another EMI filter at the AC inlet, which may be included in the connector. However, it should be noted that the leakage current limit should not be exceeded. For the most stringent CF product rating, the leakage current limit can be as low as 10 a. The leakage of external filter may directly lead to the internal leakage of AC power supply, there is a risk of interaction between external filter and internal filter, and may even worsen EMI.

Secure power solutionsThe safe solution should select the target application and specify a power supply with 2 x MOPP certification and EMC compatible performance. For example, power supplies from recom racm230-g, racm550-g and the recently released racm-1200v series.Their peak or rated power is 230W, 550W and 1200W respectively. When fans are not allowed (usually in medical environments), these products can be floor cooled. All products have 2x MOPP / 250V AC rating to prevent leakage to ground (racm550 / 1200). The safety barrier in each recom power supply is shown in Figure 2.

Figure 2: safety fence racm230 / 550 / 1200 seriesFigure 3: a 2x MOPP DC / DC converter provides SIP / SOP isolationUsing a medically certified power supply (such as the power supply of recom) is a reliable way to ensure that the safety and EMC standards required by various medical application environments are met. It would be a lower overall cost approach if development, certification costs and time to market were taken into account.

Recom is a good choice when selecting AC / DC power supply for medical equipment.
