11 beds, 80 milliliters remaining, 10 minutes remaining... "

These days, Uncle Zhang Honggen went to Shaoxing People's Hospital to hang saline solution and found several" infusion monitors "hanging in the corridor. 

The situation of patients receiving infusion in the ward was clear at a glance. 

Once the saline solution was only 10 milliliters left, the monitor would give a prompt, 

and the responsible nurse would immediately go to the patient to change the saline solution and remove the needle. 

The patient did not need to ring the bell to remind the nurse.

The infusion room has been equipped with an infusion monitoring system, 

and the hospital ward has also been renamed as the "Ringless Ward". 

The designer of this infusion monitoring system is Professor Zhang Fei from the Design Department of the School of Science and Art at Zhejiang University of Technology.

If it weren't for the fever in 2008, Zhang Fei, who specializes in industrial design,

would never have thought of developing such a medical device. 

That time when Zhang Fei was sick and hung on salt water, he was alone in the hospital without the nurse by his side. 

He felt physically uncomfortable but mentally tense, staring at the salt water bottle all the time and not daring to relax. 

Almost everyone has had the experience of hanging saline solution in the hospital. Every few minutes, 

they would look up at the bottle, worried that the saline solution had hung up, and the nurse would just leave without anyone to help them remove the needle. 

Is there an instrument that can automatically monitor the infusion situation and alert nurses of the urgent need to change the suspension bottle?

Watching the drops of saltwater fall, Zhang Fei's mind came up with the idea of inventing an infusion monitoring device. 

By using instruments to monitor the remaining time, drip rate, and even remote control of infusion, many problems can be solved, ensuring medication safety, 

allowing patients to rest assured, and nurses to avoid work omissions.

Just do what you say. Zhang Fei went to the hospital to observe the working habits of nurses and even specifically 

went to the medical equipment expo to see the trends of various manufacturers. According to the research results, 

there are no domestic or foreign manufacturers producing this type of instrument, let alone hospitals using such equipment. "

I want to be the first person to eat crab.

In order to invent this instrument, he visited thousands of hospitals, but of course, 

he was rejected countless times. After more than nine months of research and development, the first version was finally released, but through trial use, 

more than a hundred problems still appeared. "Zhang Fei did not give up, but continued to study, recording all these problems and solving them one by one. 

There are seven people in my team, all of whom are technical personnel. As soon as problems are discovered, everyone will solve them immediately.

After designing the instrument, Zhang Fei established a company, applied for a patent for the "infusion monitoring system" 

and a medical device license, explored sales channels, and spent several years before finally putting it into use. 

Nowadays, in addition to Shaoxing People's Hospital, this system has gradually been promoted in multiple hospitals in Hangzhou.
