This person named Zhang Fei is not a character from "Romance of the Three Kingdoms", 

but a university teacher with an elegant appearance. 

He comes from the School of Science and Art at Zhejiang University of Technology and is a lecturer in the Department of Industrial Design.

The experience of getting sick with a fever and hanging intravenous drip inspired Teacher Zhang

 to invent a miraculous drip hanging device - the infusion monitoring device. 

This device is now in use in hospitals and can monitor infusion time, drip rate, and even remotely. 

With this device, Teacher Zhang has obtained several invention patents.

Cold, fever, drowsiness. Who will take care of the IV drip that the patient is hanging

Entering Zhang Fei's studio, what was displayed in front of him were not pleasing foreign trade design works, 

but white display devices with hooks underneath, each hanging a common drip bag in the hospital.

Is this a medical laboratory? Zhang Fei smiled and said that these are the products he had been developing for 4 years, 

the "Infusion Monitoring System" instrument. The principle of the "infusion monitoring system" is very simple, 

which uses technologies such as gravity sensing and wireless networks to monitor the remaining amount and drip rate of liquid in the bottle.

Speaking of the invention of the "infusion monitoring system", Teacher Zhang is particularly touched. 

At the beginning of 2008, Hangzhou was extremely cold due to heavy snow, and I fell ill with a fever. 

I went to the hospital alone to see a doctor and felt very tired while hanging an IV drip in the infusion room. 

I wanted to sleep very much, but I was afraid that the liquid in the drip bottle would be finished. 

I forgot to call a nurse to pull out the needle and had to hold on, "recalled Teacher Zhang. 

At that time, Teacher Zhang was thinking that if there were an infusion monitoring device,

it would be great to issue a reminder when it was almost finished. After returning, 

Teacher Zhang gathered a team with this idea to start research and development. Conduct research and market research.

Three years of hard work and hard work have finally paid off

At the beginning, Teacher Zhang conducted extensive market research and studied the market response of this type of product. 

Later, he also went to domestic medical exhibitions to learn about the trends of medical equipment. 

He found that research on this area is not yet mature in China, and there are almost no manufacturers producing such a complete set of similar instruments.

After returning from the Medical Expo, Teacher Zhang's confidence doubled: "I worked on it for 9 months and finally released the first version,

but after trying it out, more than 100 problems still appeared." Teacher Zhang did not give up, 

but continued to research, recorded all these problems, and solved them one by one. 

There are 7 people in my team, all of whom are technical personnel. As long as they discover problems,

they will solve them immediately, "said Teacher Zhang. Only by solving the existing problems can this project be completed.

After three years of repeated improvement, in 2010, Zhang Fei finally completed the entire system, applied for a medical device license, 

and put it into market use. The product has been produced, and the next challenge is sales.

For sales, Teacher Zhang is really clueless. "I visited hundreds of hospitals for these instruments," he said. 

He started promoting the products from hospitals in second tier cities in the province, and the earliest one was in Shaoxing. 

At Shaoxing People's Hospital, the products were recognized and immediately started to be tested.

The 'Ringless Ward' in Zhejiang has been approved.

Teacher Zhang's drip hanging artifact has gone viral

Last year, Shaoxing People's Hospital adopted Mr. Zhang's "infusion monitoring system" and renamed its wards as "bell free wards", 

completely breaking away from the routine of ringing the bell to remind nurses to remove needles.

In the corridor of the silent ward in Shaoxing, there are several display screens hanging, which are "infusion monitors". 

The situation of all patients in the ward receiving infusion is clear at a glance, such as "14 beds, remaining 100 milliliters, remaining time of 15 minutes". 

Once you see that there are only 5-10 milliliters left, the monitor will issue a prompt and the responsible nurse will proactively go over to change the patient's saline solution.

In addition to the prompts on the display screen, there is also a complete set of means to provide high-quality services to patients in the ward, 

such as the secondary nurse workstation. Nurses do not sit in the nurse station, but can also receive prompts when pushing the mobile inspection RV.

Teacher Zhang said that nurses holding an Apple i Pod touch can also input the entire program into the Apple i Pod touch, 

so even when nurses go to the bathroom, they can receive prompt messages. 

The biggest advantage of using this management system is to ensure the safety of patients' medication while freeing nurses from tedious work, "said Teacher Zhang. 

In addition to Shaoxing People's Hospital, this system has gradually appeared in multiple hospitals in Hangzhou.

It may take a long time for the infusion monitoring system to be widely popularized, 

but Zhang Fei has great confidence in its products: "In the next five years, I will continue to improve, and I believe there will be a market

Product design is designed to solve problems and provide convenience. 

The appearance is simple and elegant, which can be accepted by most people. This is my design philosophy, "explained Teacher Zhang.
