I can extract side effects

Because they were busy, Wei Kang and Wei Kang only stayed in their hometown for four or five days before returning.

Although the time was short, I met all the people I should see, and spent a rare leisure time.

Overall, it was a worthwhile trip and left good memories.

The relationship between the young couple is also better, and they are like glue all day long, immersed in tenderness and sweetness.

On the first day when he came back to work, the two said goodbye to each other at the door for ten minutes, which made him late.

With a smile on his lips, Wei Kang walked along the long corridor.

When he reached the door, he realized that Lu Tingfeng was already waiting for him.

"Why are you here? Is there something urgent?" Wei Kang was a little surprised.

"Mr. Wei, the prototype of the portable color ultrasound instrument is ready."

Lu Tingfeng was waiting for the good news at the door early in the morning. He held a plastic bag in his hand and said happily.

"Ready? It's pretty fast, come in."

After entering the door, Lu Tingfeng put the bag on the table and took out all the equipment.

"Color ultrasound equipment, various types of probes, wireless charger, 10-inch tablet, couplant, are all here. The software system has also been adapted."

The portable color Doppler ultrasound instrument is quietly lying on the table, with a light and thin shape, showing a silver-white metal texture, and the workmanship is very fine, just like a handicraft.

Hold it in your hand and hold it tightly. No matter from which angle you look at it, it has a technological beauty without any flaws.

The position of the handle is equipped with a sensor. As long as you touch it, the small screen at the top will display information such as the current battery level and function mode, so that you can see the status of the device without turning it on.

Hold it in your hand, and slide your fingers gently on it, you can easily perform touch operations.

There is a Sanqing logo on the bottom of the handle. Press and hold to start the device, and press and hold again to turn it off.

"The appearance is very beautiful, with a sense of technology, let's operate it."

The appearance of the equipment is simply the embodiment of the design drawing, and Wei Kang is very satisfied with it, which perfectly fits his aesthetics.

Lu Tingfeng turned on the device, then turned on the tablet, and soon it was automatically connected to the color ultrasound system.

"The color ultrasound instrument has a built-in wireless connection module, which is configured at the factory and can be automatically connected to the tablet after it is turned on."

"The tablet's screen is 2K, 90Hz high refresh rate, built-in 128G memory, can store a large amount of images, and can also be connected to an external hard drive. It can also be used as a simple tablet computer or a portable display when there is nothing to do."

"This tablet is relatively large and needs to be charged with a cable, but we are equipped with a universal type C interface, which can share the charger." Lu Tingfeng explained: "The color ultrasound instrument can be charged directly on the wireless charger."

"Wireless charging uses the fast charging function, and it only takes 20 minutes to fully charge the battery. We have implemented a dynamic energy-saving function in the software. Under normal circumstances, it can run continuously for about 8 hours, which is enough for doctors to use outside for a whole day. gone."

After speaking, he picked up an ultrasound probe, smeared a little sterile gel on it, and stuck it directly on his neck.

There are arteries in the neck, which can verify many functions of the product.

Coupling agent is a necessary consumable for color Doppler ultrasound equipment, because generally there is air in the contact between the skin and the equipment, which can hinder the transmission of ultrasonic waves into the human body. If there is no couplant to connect the probe and the human body, it will affect the high-definition imaging effect.

After the probe was attached, a fan-shaped black and white interface immediately appeared on the screen of the tablet, which is the area for ultrasound monitoring.

Lu Tingfeng slid and clicked with his finger. He didn't know what he did to adjust it. Soon the screen flashed and was replaced by a jumping image.

"Mr. Wei, this is the arterial image. Since the blood is flowing, it drives the blood vessels to vibrate slightly, so the image is also moving."

"And look here," Lu Tingfeng pointed to the red part in the middle of the graphic, and explained: "The red part is the blood flow of the carotid artery, which is clearly marked. If you look at the liver or kidney part, it will also be marked with red and blue. The direction of blood flow is clear at a glance."

He adjusted again, and colored muscle and cortical textures, as well as blood flow, appeared on the monitor.

The resolution of the screen is very high, the display effect is very good, the image is very clear, the number of channels of the visible probe is very high, and the scanning function is very powerful.

The ultrasound probe is the core factor that determines the imaging quality, and the number of physical channels is the most important parameter of the probe. Generally speaking, the larger the number of channels, the higher the grade of color Doppler ultrasound. There are clear requirements for the number of physical channels of high-end color Doppler ultrasound, which must be higher than 128.

Of course, the quality of the image does not depend entirely on the probe, graphics processing, algorithms and hardware circuits, etc., will also affect the image quality.

However, the number of channels of the probe is the basis, just like a display, when the resolution is low, no matter how much you optimize the picture, it will not make it clearer.

The probe used by Lu Tingfeng has 256 physical channels, coupled with key imaging technology and multi-modal technology, it is possible to have such a good imaging effect.

"Mr. Wei, this is 4D real skin rendering technology. The image is more three-dimensional, more realistic, and the picture is clearer. It is generally used to show pregnant women to check the baby inside. It is really a sledgehammer to use it on my neck."

The so-called 4D function is actually based on the three-dimensional image, adding the dimension of time, so that you can see the real-time dynamic graphics of the internal organs of the human body.

If you want to see what the baby is doing in the mother's womb, only a 4D color Doppler ultrasound can do it.

In short, 3D is a three-dimensional image, and 4D is a real-time dynamic image, which is a very important detection method for obstetrics and gynecology and clinicians.

"Mr. Wei, this portable color ultrasound instrument is so easy to use. I have never seen such a powerful product. I never thought that medical equipment could be so small and convenient."

"This idea of ​​making products is absolutely groundbreaking. It's like switching from a functional phone to a smart phone."

Lu Tingfeng showed off vigorously, becoming more and more excited, and his mouth was full of praise.

In fact, when he first saw the blueprints, he didn't have a deep feeling. It wasn't until after the prototype was made and he experienced it himself that he realized the abnormality of this product.

With its powerful functions and convenient operation, it really leaves the competing products far behind.

It can be said that what is stronger than it is not as portable as it is, and what is more portable is not as strong as it is.

It is strong and small, and it is an epoch-making product.

Medical equipment is a multi-disciplinary product, involving software, hardware, medicine, sensors and other fields. The products produced have very high technical content, which can be said to be the perfect fusion of machinery and medicine.

Color Doppler Ultrasound is a high-end medical equipment integrating acoustic materials, information detection, electronic technology, microcomputer technology, image processing, precision technology and other multi-disciplinary advanced technologies.

Even though he has been in the industry for more than 20 years, he dare not say that he understands everything, he can only scratch the surface.

Even a little progress in such an interdisciplinary field is not easy, and it often takes years of hard work by engineers to achieve it.

To make a portable color ultrasound instrument like Sanqing, one can imagine how difficult it is and how advanced the technology is.

Wei Kang chuckled, and was also very satisfied with the displayed results: "It's very good, it seems that we can enter the next stage soon."

"Color ultrasound equipment belongs to the second class of medical devices. It is reasonable to conduct clinical trials. However, our ultrasound equipment is a product with high maturity and low risk. It meets the requirements for exemption from clinical trials and is also included in the national test exemption catalogue. Therefore, You can go directly to the hospital for a trial."

Lu Tingfeng said confidently: "I already have a plan for this. The previous portable monitor sold well, and it has accumulated a good reputation, and customers also recognize the Sanqing brand. So I just need to proceed as usual."

"First send a batch of samples to the hospital for trial use, and then adjust according to the feedback. After the product has been used without any problems, it can be officially sold."

"I believe that as long as the hospitals that have tried it will be deeply impressed by this product, they will definitely not worry about selling it."

Seeing his smug look, Wei Kang couldn't help laughing: "I hope so."

*****

Lu Tingfeng happily walked into the elevator room, pressed the floor button, and waited for the elevator to start.

The work report just now was very successful, especially showing the imaging effect on himself, which left a deep impression on Mr. Wei.

Seeing that the elevator door was about to close, it suddenly opened again with a ding.

A woman with a big belly and wearing a protective suit walked in. She was in her early thirties, with beautiful features and very loose clothes.

When she saw Lu Tingfeng, her eyes lit up: "Mr. Lu, long time no see. What have you been up to?"

Lu Tingfeng recognized that this was a supervisor of the finance department. He usually had a lot of dealings with him, so he hurriedly greeted him.

"So it's Miss Zhou. I'm busy with a new project recently, but you're pregnant with your second child again. You're quick enough. How many months has it been?"

Zhou Juan smiled: "Many female colleagues are pregnant this year, and I am also a little bit moved. Thinking about what they said, one child is still a bit lonely, and it is good for two children to have a companion. No, it has been 30 weeks .”

"Hehe, that's good, more children, more blessings." Lu Tingfeng said with a chuckle.

Zhou Juan glanced at the bulging plastic bag in his hand, and asked curiously, "What new equipment have you researched?"

Speaking of this, Lu Tingfeng suddenly got excited and talked endlessly.

"This is a new achievement of our equipment department. The all-digital portable color Doppler ultrasound instrument is very small and convenient. It can check various organs of the body anytime and anywhere. It can not only check the abdominal organs such as the heart, liver and kidney, but also be used in obstetrics and gynecology. Fetal examination of..."

The technical terms in his mouth jumped out one after another, Zhou Juan was in a fog, but she still understood the word color ultrasound instrument, knowing that it was a device that could check the development of the fetus.

When I usually go for antenatal checkups, I have to go into the color ultrasound room every time, and use something to move around on the belly, so that I can see the appearance of the baby in the belly.

So, she brightened her eyes and said, "Can this see the baby in my stomach clearly?"

Lu Tingfeng's voice stopped abruptly, and he nodded, "Yes, not only can I see clearly, but I can also see the real-time dynamic image of the fetus."

"Wow!" Zhou Juan said with a look of surprise: "I went to the hospital and saw a very large color ultrasound instrument. If you want to put it in the room, can it fit in such a small bag in your hand?"

"Hehe," Lu Tingfeng said with a look of disdain, "Of course, how about this is an epoch-making scientific and technological achievement."

"Great, why don't you give it to me for a try? It's all from the same company, so you should be able to try it out." Zhou Juan rubbed her hands excitedly and approached with a smile.

Lu Tingfeng pondered for 3 seconds before saying: "Yes, but you have to follow me to the testing room, I can't give you the things directly."

Zhou Juan nodded excitedly: "Okay, let's treat it as a free prenatal checkup."

Lu Tingfeng's footsteps paused, his face darkened, and he thought that if it wasn't for the clinical experiment data, I wouldn't let you try it so casually.

When the two came to the testing room of the equipment department, they happened to see a group of people surrounding it.

On the small bed in the middle lay a young man, his clothes lifted up, exposing his chest.

Wang Dali stood aside, applying coupling agent to the ultrasound probe.

While wiping it, he comforted, "Be patient, the coupling agent is a bit cold, I'm too lazy to heat it up with a heater, anyway, you're a big man, it's okay to cool down a little bit."

As he spoke, he pressed the probe to the young man's chest: "Look, everyone, the high-end and high-end heart color Doppler ultrasound examination has begun. If you don't see nothing, don't look at it."

On the opposite wall, a 50-inch display screen was hung, displaying his operations in real time.

It can be seen that there are various inspection items in the catalog, in addition to the heart, there are also abdominal, urinary, mammary gland, fetus, bone and so on.

Wang Dali tapped the handle of the color Doppler ultrasound instrument lightly, and selected the item of heart examination.

A fan-shaped black and white interface soon appeared on the screen, and the picture was constantly changing.

"Hey! This is the heart. Sure enough, young people are good. The heart beats so powerfully."

Everyone could tell at a glance that it was a beating heart, and immediately someone laughed and made a joke.

Wang Dali swiped again, and red and blue color blocks appeared on the original black and white image.

"Blood flow signal! It's very clear!" Someone exclaimed again.

Red represents the direction of blood flow to the probe, and blue represents blood flow away from the probe, which is a function of high-end color Doppler ultrasound.

With the rotation of the probe, the entire structure of the heart clearly appears on the screen.

You can see the remaining holes, you can see the thickening of the valves, you can see the left and right ventricles of the heart, and the blood flow through these places.

Everyone held their breath and looked carefully. This was the first time they saw the heart structure of the human body in the office.

I used to see this thing in the color ultrasound room of the hospital, and I would lie on the bed and glance at it from a distance. It was impossible to see it so carefully.

Now, they can watch as long as they want.

"Hey, you guys are enough, my butt hurts from lying down for so long, I don't have any secrets anymore."

The young man lying there grew impatient and began to curse.

At this time, Lu Tingfeng who was standing at the door coughed lightly.

The audience fell silent, so quiet that a needle could be heard falling on the ground.

Wang Dali turned his head with difficulty and squeezed out a smile: "Head, you are back, is Mr. Wei satisfied with his work?"

Lu Tingfeng said with a stern face, "I've only been gone for a while, and you've let yourselves go."

Wang Dali smiled and was about to speak.

Lu Tingfeng waved his hand and introduced Zhou Juan beside him.

"This is Miss Zhou from the Finance Department. She is more than seven months pregnant and wants to use a color Doppler ultrasound to see the baby in her stomach. Wang Dali, since you are so hardworking, you can do it."

The lying young man sat up straight, and rolled down swiftly without wiping off the gel remaining on his chest.

Zhou Juan chuckled: "Your work atmosphere is quite lively and interesting." After speaking, she lay down.

With a serious face, Wang Dali picked up a probe protruding like a goose egg, coated it with gel, and slowly slid it on her stomach.

Soon, a picture appeared on the screen again.

However, this time the picture was clearer. Everyone could see that the outline of a baby appeared in the middle of the screen.

Zhou Juan was lying on the bed, looking at the big screen opposite, with a gentle smile on her face.

Lu Tingfeng frowned and said, "Dali, you talk a lot, why don't you explain to Miss Zhou."

Wang Dali gave a dry laugh, and said slowly, "You can see that this is a real three-dimensional image, very clear."

"Moreover, our color Doppler ultrasound machine can also intelligently detect the face of the fetus, and then display it. Look, this is the face of a baby. It's so cute and touching. Just looking at it makes my heart drunk."

Looking at the baby's immature face, Zhou Juan's eyes became tender, and she couldn't help murmuring: "Baby, Mommy is here to see you."

After a while, Wang Dali continued, "Let's see what the baby is doing."

He manipulated it, and the screen suddenly moved.

I saw the little baby moving around on the screen, suddenly stretched out his little hand, and touched it in the direction of the probe.

"Ah, it moved, he moved." Zhou Juan cried out excitedly, and immediately covered her mouth.

From the eyes of everyone in front of the screen, it seemed that the little baby wanted to reach out and give everyone a high five.

"Wow!" Immediately someone cheered: "The baby is too sensible, and will give us high fives."

Everyone laughed and felt heartwarming.

Of course they don't know, such a small baby actually doesn't understand this at all, but they are stimulated by the ultrasound probe and feel that there is something here, so they want to reach out and touch it.

"Wow, I see, he is a beautiful little boy." Wang Dali suddenly called out.

Everyone immediately smiled knowingly, it turned out that he turned the screen again, revealing the baby's gender.

Ordinary three-dimensional color Doppler ultrasound requires a doctor to distinguish these, but 4D color Doppler ultrasound can clearly and intuitively see gender characteristics.

Surprised and delighted, Zhou Juan covered her mouth and cried out: "Wow, that's great, I already have a daughter, and this time I really have both sons and daughters."

Most doctors would not intentionally disclose the gender, and she herself could not understand the color Doppler ultrasound images, and she didn't care about it, so she still didn't know the baby's gender.

I didn't expect to get a surprise today.
