On the other end of the video, Tang Jinnan said with thin lips, "Mom, I have something to trouble you."

Ms. Tang Yue put down the scented tea and waved to the person who had just entered. The person immediately retreated consciously. She curled up her legs, clasped her hands around her chest and sighed, "Oh, it's not easy. My son still remembers that he has a mother. I thought he had forgotten it long ago."

"You call mom when you have something to do, but you don't even call when you don't have anything to do. Haha."

Tang Jinnan was not surprised by Ms. Tang Yue's reaction. He selectively ignored it and said, "I sent you a few photos via email. Take a look."

"...Why, find me a daughter-in-law for me to take a look." Ms. Tang Yue said as she turned on the computer next to her. She was stunned when she saw the photo. It was not a daughter-in-law, but a machine.

She continued to complain while browsing, "All day long, it's either medicine, machines, or research."

"You left for more than half a year without a word. The first time you contacted me was to ask me to help you make fake information to deceive Li Jiantian."

"The second time, it was to show your mother a bunch of machines. You want to piss me off by telling me how devoted you are to research, right?"

Ms. Tang Yue glanced at her son in the video.

Tang Jinnan said in a good-tempered voice, "Nothing. Contacting you is no different from telling the teacher where I am."

Ms. Tang Yue frowned.

Tang Jinnan didn't wait for her to speak again, and said directly, "The thing in the picture is a modified version of a heart rate monitor. It weighs no more than two kilograms. The monitoring accuracy is currently more than 90%. It has not been formally tested on a large scale on patients with myocardial infarction."

Ms. Tang Yue was stunned, "You said two kilograms?"

As the top family in the imperial capital, the Tang family is not only well-informed, but also has a wide range of business.

Most of the medical equipment in major hospitals in Central City is provided by the Tang family. What kind of equipment a heart rate monitor is can be afforded, but it is not convenient not to consider it. Ms. Tang Yue knows better than anyone that if such an improved device with an accuracy rate of more than 90% appears, then Tang Yue can almost imagine how much convenience it will bring to today's society.

"What specific detection rate do you mean?"

"Is it the problem of being able to diagnose physical and cardiovascular diseases, or..."

"Check the email." Tang Jinnan said briefly.

He sent all the equipment information in the email.

Ms. Tang Yue spent half an hour to read it. It is different from the electrocardiograph used in medical equipment. This one is closer to a home portable device. However, Ms. Tang Yue was a little disappointed. "The accuracy rate is 90% when used on four people, which is useless."

Four people, the base number is too small.

It must pass clinical trials and be used on cardiovascular and cerebrovascular patients, and the number of patients must exceed three digits. The accuracy rate must reach at least 50%, which means that it must be able to detect more than 50 out of 100 myocardial infarction patients to pass the test.

At the same time, it should not only be used on patients who have already been found to have problems. After all, when patients take medicine for treatment, their body values ​​will fluctuate differently from those of ordinary people. Therefore, it must also be tested on patients who have not been diagnosed. The accuracy rate must also reach 50% under the three-digit base to pass.

"So we have to experiment." Tang Jinnan said calmly.
