Moxa’s Serial-to-wifi Device Server Helps Build Hospital Information Systems

The healthcare industry is rapidly going digital. Reducing human errors and improving operational efficiency are important factors driving the digitalization process, and the establishment of electronic health records (EHR) is the top priority of this process. The development of EHR needs to collect a large amount of data from medical machines scattered in various departments of the hospital, and then convert valuable data into electronic health records. Currently, many hospitals are focusing on collecting data from these medical machines and developing hospital information systems（HIS）.

These medical machines include dialysis machines, blood glucose and blood pressure monitoring systems, medical carts, mobile diagnostic workstations, ventilators, anesthesia machines, electrocardiogram machines, etc. Most medical machines have serial ports, and modern HIS systems rely on serial-to-Ethernet communication. Therefore, a reliable communication system connecting the HIS system and medical machines is essential. Serial device servers can play a key role in data transfer between serial-based medical machines and Ethernet-based HIS systems.

ONE: Three poins for Building a Reliable HIS

 

1: Solve the problem of connecting with mobile medical machines
Many medical machines need to move constantly in the ward to serve different patients. When the medical machine moves between different APs, the serial port to wireless device networking server needs to roam quickly between APs, shorten the switching time, and avoid connection interruption as much as possible.

2: Prevent unauthorized access and protect sensitive patient information
The serial port data of the hospital contains sensitive patient information and needs to be properly protected.
This requires the device networking server to support the WPA2 protocol to establish a secure wireless connection and encrypt serial data transmitted wirelessly. The device also needs to support secure boot, allowing only authorized firmware to run on the device, minimizing the risk of hacking.

3: Protect communication systems from interference
The device networking server should adopt the key design of locking screws to prevent the medical cart from being interrupted due to constant vibration and impact during the movement of the power input. Additionally, features such as surge protection for serial ports, power input and LAN ports enhance reliability and reduce system downtime.

Two: it meets safety and reliability requirements

 

Moxa's NPort W2150A-W4/W2250A-W4 series serial-to-wireless device servers provide secure and reliable serial-to-wireless communication for your HIS system. The series offers 802.11 a/b/g/n dual-band network connectivity, ensuring easy connection of serial-based medical machines with modern HIS systems.

In order to reduce packet loss in wireless network transmission, Moxa’s serial port to wireless device networking server supports fast roaming function, enabling the mobile medical vehicle to realize seamless connection between different wireless APs. Plus, offline port buffering provides up to 20MB of data storage during unstable wireless connections. In order to protect sensitive patient information, Moxa's serial port to wireless device networking server supports secure boot and WPA2 protocol, which comprehensively strengthens device security and wireless transmission security.

As a provider of industrial connectivity solutions, Moxa has designed screw-locking power terminals for this series of serial-to-wireless device servers to ensure uninterrupted power input and surge protection, thereby improving device stability and reducing system downtime.
