security solutions

It must be made clear at the beginning that IT, that is, the job of an expert in information technology infrastructure in medical places, is actually the group of guys who specialize in messy but super important things like computers, networks, databases, etc. in hospitals – they are not ordinary computer games, they are all technical tasks that are related to various departments and medical equipment in the hospital all day long!

The IT infrastructure of medical places, simply put, is the "skeleton" of all the information systems of the hospital, including the construction of computer rooms where the server is hidden, the placement and maintenance of computer equipment used by doctors and nurses' workstations, the laying and daily maintenance of network lines connecting the entire hospital, the construction and security protection of databases that store patient medical records. Yes, there are also systems such as electrocardiogram machines and CT scanners that connect to computers, and even the technical guarantees of audio and video required for remote consultation are included! If no one cares about these things and causes some trouble, not only doctors and nurses will feel uncomfortable and frustrated in their work, but even patients may be delayed by the treatment of medical treatment. "Provide global procurement services for weak-current intelligent products!" This sentence is here. It may be useful for these experts to buy things, I guess it is.

So what specific and critical tasks do these experts do in daily life? You will know if I nag you:

1. Daily maintenance and fault repair of hardware equipment : That is, whether it is an all-in-one machine used in the hall registration or a particularly expensive medical computer in the operating room, as long as there is a problem with the hardware objects that use electricity or network, such as the machine cannot be turned on, the blue screen is stuck, the USB interface cannot be plugged in, and nothing can be reacted. When experts receive the call, they have to run over and see what's going on. If they can repair it on site, they will be done immediately. If they really can't handle it, they have to contact a new one or apply for a manufacturer to repair it. They must always restore the equipment quickly and can't be "closed" for too long!

2. The network channel is smooth and guaranteed and safeguarded : The hospital network is very complicated. There are internal networks used by doctors and nurses, and the external network area for guest access in the outpatient halls used by patients' families. Experts must separate and understand these networks of different uses and confidentiality levels clearly and understand. Don't mess around. From time to time, you have to check whether the transmission speed is fast enough and whether the connection will be suddenly disconnected. For example, if the transmission is transmitted by the imaging department, it will be stuck and unable to move halfway, how anxious it is! More importantly, we must beware of the hackers outside who want to sneak in and steal patient information and disrupt the normal hospital medical treatment order, so we have to install various firewall programs, intrusion detection systems, and these "iron fences" that protect the network gate!

3. Software system installation, deployment, upgrade and update : such as the HIS system used in the hospital (a complete set of hospital information management systems, which control hospitalization, registration, and charges), LIS laboratory systems (responsible for blood tests and urine tests), PACS video reading systems (special video viewing software for watching X-rays), these messy core business software with different functions, from the beginning to adjusting settings according to the different working habits of each department such as internal medicine and surgery departments, and the software company has released a new version or patched vulnerabilities to upgrade the system. They have to follow up and do it properly, and they have to do it while teaching the department to use new places!

4. Data backup and archive and emergency backup plan formulation drill : the patient's medical records and various inspection data results are expensive, so experts must regularly arrange to backup these important data systematically and store them in a safe storage disk. If the large hard drive suddenly breaks and can't start, accidentally delete the entire file and cannot be found, and even some unlucky hospitals encounter a particularly large natural disaster and destroy the machine, they can take out the backups they saved before and get the data back and rebuild the system. Of course, after this matter is over, you have to summarize your experience and refine what it is called… Oh, connect with the disaster recovery system plan and organize everyone to practice and operate according to the drill.

A few common questions you ask, listen to what the experts say, I will learn it:

Question: Why do medical IT have to use enterprise-level storage devices that look super expensive when making databases? Can't it be possible to plug in a large-capacity hard drive on a computer?

Answer: This is far from each other and is not the same thing at all! Enterprise-level storage is not only larger than many single hard drives with a single hard drive, but also a huge size. Its continuous high-intensity reading and writing speed is not something that ordinary hard drives can catch up. Take the time of the clinic opening in the morning of our hospital for example. Many doctors' workstations and settlement charging windows must use data to retrieve and refresh the information table at the same time. If you put a normal hard drive on, you will definitely open a page and stare at the screen and wait for a long time to load a red circle and turn around. People are so anxious that they stomp their feet! Moreover, it has many particularly powerful functions to protect data, such as writing data to two unconnected places (called mirrored ones), breaking a hard disk, changing the machine immediately without turning it off, replacing it in the background immediately (it seems to be a magical skill like hot standby), and having a power outage, and a battery cache can save half of the data written (it's called power-down protection anyway). In these aspects, ordinary hard drives are like small rafts and aircraft carriers, which are incomparable and cannot be seen in front of each other, let alone the risk of data loss, the consequences that the hospital cannot afford at all, would be too scary.

Q: Can the hospital network speed be faster? Sometimes you have to wait for dozens of seconds to transmit patient medical record information. I think it's too slow. Is this an expert not doing it?

Answer: If you can't come up, just blame the experts for not being able to do it… The reasons for the network speed and slow lag can be complicated. There may be problems in several aspects! You have to step by step to check: First, you have to see if the network cable has been damaged a lot and the interface is intact. Sometimes you can see if it is inserted in but it is not in place and it is loose. It is disconnected instantly when it is connected to too many devices. If the switch is so tired that it is too exhausted to be busy. Then think about whether the computer of a certain department is accidentally infected with a virus secretly sending something out in the background. Or doctors and nurses are passing large files while watching online movies and P videos. Finally, some old medical equipment and equipment that have not been replaced for a long time. The network interface and protocol are relatively old and slow to crawl like an old turtle. Experts, it is impossible to get along with the current fast network environment. At this time, experts have to think about how to get a balance point to adapt! Anyway, you have to check the Internet crazy on the spot to find out what the problem is. You can’t just blame others for not doing it properly!

I personally think that the job of IT really requires a very meticulous and patient "embroidery skill" to figure out the dense lines and various annoying code configurations, and also has a particularly powerful resistance to stress like the Hercules moving things. After all, if there is a problem with the medical system, it will be a juncture when your life is a little slower. They are like "technical city gate officials" guarding a particularly important city, silently supporting them behind their backs, so that the hospital, a super-large and complex institution, can rotate bit by bit and smoothly. In general, these experts hiding behind the screen and in the computer room have a great contribution to the entire hospital being able to serve patients!
