Because they were both busy, Wei and Kang only stayed in their hometown for four or five days before returning.
Although the time was short, I met everyone I needed to meet and spent some rare leisure time.
Overall, it was a worthwhile trip and I left with wonderful memories.
The relationship between the young couple has also become better. They are inseparable all day long, immersed in tenderness and sweetness.
On his first day at work after returning, the two of them stood at the door and said goodbye for ten minutes, which made him even late.
Wei Kang walked down the long corridor with an aftertasteful smile on his lips.
When he arrived at the door, he found 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 system is ready."
Lu Tingfeng was waiting at the door early in the morning to announce the good news. He was holding 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 the entire set of equipment.
"The color ultrasound system, various probes, wireless chargers, 10-inch tablets, and couplant are all here. The software system has also been adapted."
The portable color ultrasound instrument lies quietly on the table. It is light and thin in appearance, has a silver-white metallic texture, and is very finely made, just like a handicraft.
Hold it in your hand and hold it tightly. No matter which angle you look at it, it has a sense of 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 the current battery level, functional mode and other information, so that you can see the status of the device without turning it on.
Holding it in your hand, you can easily perform touch operations by gently swiping your fingers on it.
There is the Sanqing logo on the bottom of the handle. Press and hold to start the device, and press and hold again to turn it off.
"It looks very beautiful and has a sense of technology. Come and see how it works."
The appearance of the equipment is simply the embodiment of the design drawings, and Wei Kang is very satisfied with it, as it perfectly fits his aesthetic.
Lu Tingfeng started the device, then turned on the tablet, and soon it was automatically connected to the color ultrasound system.
"The color Doppler ultrasound instrument has a built-in wireless connection module, which is configured at the factory and can automatically connect to the tablet after it is turned on."
"The screen of the tablet is 2K, 90Hz high refresh rate, and has a built-in 128G memory. It can store a large number of images and can also be connected to an external hard drive. It can also be used as a tablet with simple functions or a portable monitor when nothing happens."
"This tablet is relatively large and needs to be connected to charge, 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, which can fully charge the battery in just 20 minutes. 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. ”
After speaking, he picked up an ultrasound probe, applied a little disinfectant coupling agent on it, and placed it directly on his neck.
There are arteries in the neck, which can verify many functions of the product.
Coupling agent is an essential consumable for color Doppler ultrasound equipment, because there is generally air in contact between the skin and the equipment, which can hinder the transmission of ultrasonic waves into the human body. If there is no coupling agent to connect the probe and the human body, the high-definition imaging effect will be affected.
After the probe is attached, a fan-shaped black and white interface immediately appears on the flat screen, which is the area for ultrasound monitoring.
Lu Tingfeng slid his fingers and clicked. He didn't know what operation he made to adjust. Soon the screen flashed and was replaced by a beating image.
"Mr. Wei, this is an image of an artery. Because the blood is flowing, it causes the blood vessels to tremble 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 carotid artery blood flow, which is clearly marked. If you look at the liver or kidneys, they will also be marked in red and blue. The direction of blood flow is clear at a glance.”
He adjusted it again, and colorful muscles and cortical textures, as well as the flow of blood, appeared on the display.
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 greater the number of channels, the higher the grade of color ultrasound. There are clear requirements for the physical channels of high-end color ultrasound, which must be higher than 128.
Of course, the quality of the image does not entirely depend on the probe, graphics processing, algorithms and hardware circuits, etc., which will also affect the image quality.
However, the channel number of the probe is the basis, just like a monitor. When the resolution is low, no matter how you optimize the picture, it will not make it clearer.
The probe used by Lu Tingfeng has 256 physical channels. With key imaging technology and multi-modal technology, it can achieve such a good imaging effect.
"Mr. Wei, this is 4D real-skin rendering technology. The image is more three-dimensional, more lifelike, and the picture is clearer. It is generally used to check the baby inside the pregnant woman's body. When used on my neck, it is really overkill."
The so-called 4D function actually adds the dimension of time to the three-dimensional image, allowing you to see real-time dynamic graphics of the organs in the human body.
If you want to see what the baby is doing in the mother's belly, only a color ultrasound with 4D function can do it.
In short, 3D is a three-dimensional graphic, and 4D is a real-time dynamic image. These are very important detection methods for obstetricians and gynecologists and clinicians.
"Mr. Wei, this portable color ultrasound machine is so easy to use. I have never seen such an awesome product. I never thought that medical equipment could be so small and convenient."
"This idea of making products is absolutely groundbreaking. Using it is like switching from a functional phone to a smart phone."
Lu Tingfeng showed it hard, getting more and more excited, and his mouth was full of words of praise.
In fact, he was not very impressed when he first looked at the drawings. It was not until he personally experienced it after the prototype was made that he understood the abnormality of this product.
Its powerful functions and convenient operation really put it far behind competing products.
It can be said that the ones that are stronger than it are not as portable as it is, and the ones that are more portable than it are not as strong as it.
Powerful yet small, it is the ultimate product. It is an epoch-making product.
Medical devices are a multi-disciplinary product, involving software, hardware, medicine, sensors and other fields. The products produced have a very high technical content and can be said to be a perfect fusion of machinery and medicine.
Color ultrasound is a high-end medical equipment that integrates multi-disciplinary advanced technologies such as acoustic materials, information detection, electronic technology, microcomputer technology, image processing, precision technology, etc.
Even though he has been in the industry for more than 20 years, he does not dare to say that he knows everything. He can only scratch the surface.
Even a small amount of progress in such an interdisciplinary field is not easy and often requires engineers to work hard for many years to achieve it.
As for making a portable color Doppler ultrasound instrument like Sanqing, you can imagine how difficult it is and how advanced the technology is.
Wei Kang smiled and was very satisfied with the results displayed: "It's great. It seems that we can enter the next stage soon."
"Color ultrasound equipment is a Class II medical device and is subject to clinical trials. However, our ultrasound equipment is a highly mature and low-risk product that meets the requirements for exemption from clinical trials and is also included in the exemption catalog promulgated by the state, so you You can go directly to the hospital to try it out.”
Lu Tingfeng said confidently: "I already have a plan for this. The previous portable monitors sold well and have accumulated a good reputation. Customers also recognize the Sanqing brand. So I just need to push forward as usual."
"First send a batch of samples to the hospital for trial use, and then make adjustments based on feedback. Once the product is used and there are no problems, it can be officially sold."
"I believe that any hospital that has tried it will be deeply impressed by this product and will definitely not worry about selling it."
Seeing his complacent look, Wei Kang couldn't help but smile: "I hope so."
****
Lu Tingfeng walked into the elevator happily, pressed the floor button, and waited for the elevator to start.
The work report just now was very successful, especially the imaging effect demonstrated on myself, which left a deep impression on President Wei.
Just as the elevator door was about to close, it suddenly opened again with a ding.
A woman with a big belly and wearing protective clothing walked in. She was in her early thirties, with beautiful features and very loose clothes.
Her eyes lit up when she saw Lu Tingfeng: "Mr. Lu, long time no see. What have you been busy with lately?"
Lu Tingfeng recognized that this was a supervisor from the finance department, and he had many interactions with him, so he quickly said hello.
"It turns out to be Miss Zhou. I've been working on a new project recently, but you're pregnant with your second child again. You moved quickly enough. How many months have you been here?"
Zhou Juan smiled: "Many female colleagues are pregnant this year, and I'm a little excited. Thinking about it, they are right. One child is a bit lonely, and it's better to have two children with you. No, it's already 30 weeks. .”
"Haha, that's good. Having more children means more blessings." Lu Tingfeng said with a smile.
Zhou Juan glanced at the bulging plastic bag in his hand and asked curiously: "What new equipment have you developed?"
Speaking of this, Lu Tingfeng suddenly got excited and talked endlessly.
"This is a new achievement of our equipment department. The fully digital portable color ultrasound instrument is very compact and convenient. It can be used to examine various organs of the body anytime and anywhere. It can not only examine abdominal organs such as the heart, liver and kidneys, but can also be used in obstetrics and gynecology. Fetal examination..."
Zhou Juan was confused as he kept spouting professional terms one after another, but she still understood the word color ultrasound and knew that it was a device that could check fetal development.
When I usually go for a prenatal check-up, I have to go into the color Doppler ultrasound room every time and move something on my belly to see what the baby looks like in my belly.
So, her eyes shone brightly and she said, "Can this clearly see the child in my belly?"
Lu Tingfeng's voice stopped suddenly and he nodded: "Yes, not only can you see clearly, but you can also see real-time dynamic images of the fetus."
"Wow!" Zhou Juan said with a surprised look on her face: "The color Doppler ultrasound machine I saw when I went to the hospital was very big. It needs to be placed in the room. How can it be accommodated in such a small bag in your hand?"
"Haha," Lu Tingfeng said with disdain, "Of course, otherwise we can say that this is an epoch-making scientific and technological achievement."
"That's great, why don't you give it to me to try? They are all from the same company, so you should be able to try them out." Zhou Juan rubbed her hands excitedly, smiled and came over.
Lu Tingfeng pondered for 3 seconds before saying, "Okay, but you have to follow me to the testing room. I can't give you anything directly."
Zhou Juan nodded excitedly: "Okay, let's treat it as a free prenatal check-up."
Lu Tingfeng paused and his face darkened, thinking if it was for the clinical trial data, I wouldn't let you try it so casually.
The two came to the testing room of the equipment department and saw a bunch of people gathered inside.
There was a young man lying on the small bed in the middle, his clothes lifted up, exposing his chest.
Wang Dali stood aside and was applying coupling agent to the ultrasound probe.
While wiping it, he comforted: "Please bear with it, the coupling agent is a bit cold, and I'm too lazy to use a heater to heat it up. Anyway, you are a big man, and it will be fine if you cool it down a few times."
As he spoke, he pressed the probe against the young man's chest: "Look, everyone, the high-end and high-end cardiac color ultrasound examination has begun. It's not in vain."
On the opposite wall, a 50-inch display screen hung, showing his operations in real time.
As you can see, there are a variety of examination items on the catalog, in addition to the heart, there are also abdominal, urinary, breast, fetal, skeletal, etc.
Wang Dali gently tapped the handle of the color Doppler ultrasound machine and selected the cardiac 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 some people immediately started laughing and joking.
Wang Dali swiped again, and red and blue color blocks appeared on the originally black and white image.
"The blood flow signal! It's very clear!" Someone else exclaimed.
Red represents the blood flow toward the probe, and blue represents the blood flow away from the probe. This is a high-end color ultrasound function.
As the probe rotates, 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 them.
Everyone held their breath and looked carefully. This was the first time they saw the human heart structure in an office.
I used to see this thing in the color ultrasound room of the hospital, and I always glanced at it from a distance while lying on the bed. It was impossible to look at it so carefully.
Now, they can watch it for as long as they want.
"Hey, hey, that's enough. My butt hurts from lying down for so long. Damn, I don't have any secrets anymore."
The young man lying there became impatient and began to curse.
At this time, Lu Tingfeng, who was standing at the door, coughed lightly.
The whole place fell into silence, so quiet that you could hear a pin drop.
Wang Dali turned his head with difficulty and forced a smile: "Tou, you are back. Are Mr. Wei satisfied with your work?"
Lu Tingfeng said with a straight face: "I have only been gone for a short time, and you have already let yourself go."
Wang Dali smiled sarcastically and was about to speak.
Lu Tingfeng waved his hand and introduced Zhou Juan next to him.
"This is Miss Zhou from the Finance Department. She is more than seven months pregnant. She wants to use a color ultrasound to see the baby in her belly. Wang Dali, since you are so enthusiastic, you can do it."
The young man who was lying down suddenly sat up and rolled down quickly without even having time to wipe the remaining coupling agent on his chest.
Zhou Juan chuckled lightly: "Your working atmosphere is quite lively and interesting." After that, she lay down.
With a serious look on his face, Wang Dali picked up a protruding probe like a goose egg, applied coupling agent, and slowly slid it on her belly.
Soon, a picture appeared on the screen again.
However, this time the picture was clearer, and 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 it to Beauty Zhou?"
Wang Dali laughed dryly and said slowly: "As you can see, this is a real three-dimensional image, very clear."
"Moreover, our color ultrasound machine can intelligently detect the face of the fetus and then display it. Look, this is the face of the baby. It is so cute and moving. It makes me drunk just by looking at it."
Zhou Juan looked at the baby's tender face, her eyes became tender and watery, and couldn't help but murmured: "Baby, mommy is here to see you."
After a while, Wang Dali continued: "Let's see what the baby is doing."
He operated it, and the screen suddenly moved.
I saw the baby moving around on the screen, and suddenly stretched out his little hand and touched it in the direction of the probe.
"Ah, it's moving, he's moving." Zhou Juan cried out excitedly, and then immediately covered her mouth.
To the people in front of the screen, it seemed like the baby wanted to reach out and give everyone a high-five.
"Wow!" Someone immediately cheered: "The baby is so sensible, he even gives us high fives."
Everyone laughed and felt heartwarming.
Of course, they didn't know that such a young baby didn't understand this at all. He was just stimulated by the ultrasound probe and felt that there was something here, so he wanted to reach out and touch it.
"Wow, I saw it, it's a beautiful little boy." Wang Dali suddenly shouted.
Everyone suddenly smiled knowingly. It turned out that he had rotated the screen again to reveal the gender of the baby.
Ordinary three-dimensional color ultrasound requires a doctor to distinguish these, but 4D color ultrasound can clearly and intuitively see gender characteristics.
Zhou Juan was surprised and happy, covering her mouth and shouting: "Wow, that's great, I already have a daughter, and this time I really have both children."
Most doctors would not disclose the baby's gender intentionally, and she couldn't read color ultrasound images, and she didn't care about it, so she still didn't know the baby's gender.
Unexpectedly, I got a surprise today.
