Chapter 8 Chapter 8 Micro Monitor

By the time Frances and Posov arrived in the hall, the medical conference had already begun.All personnel are present, including the astronauts and more than two dozen engineers and scientists supporting Operation Rama.In addition, four newspaper reporters and a group of TV station staff were also present. Nicole de Jardin, wearing his usual gray flight suit, stood on the podium ahead, holding a laser pointer.Next to her, a tall Japanese man in a blue jacket listened carefully to questions from the audience below. Nikol greeted Posov and introduced to the Japanese: "Dr. Hamamatsu, this is our commander, General Vanar Posov of Russia; this is space reporter Frances Sabatini .”

She turned to the two later introductions and said: "This is the famous Dr. Hamamatsu, who designed this human body monitoring system that will be used in operations. The micro-monitors of this system will be implanted in the body of each team member. " Posov held out his hand: "It's very nice to meet you, Dr. Hamamatsu." He said, "Mrs. de Jardin has introduced your masterpiece to us many times." "Thank you." After shaking hands with Posov, Dr. Hamamatsu bowed to him, "It is a great honor to contribute to Operation Rama." Frances and General Posov found two vacant seats and the meeting resumed.

Next to the small podium, next to a 1:1 wall chart, there is a row of buttons.Nicole touched one of the keys with a laser beam, and a three-dimensional holographic image of human blood circulation appeared in front of the podium.Veins are blue, arteries are red, and some small white light spots circulate in the blood vessels, showing the direction and speed of blood flow. "The Life Sciences Directorate of the International Space Agency finally approved the use of this new monitor implanted in the human body in Operation Rama last week to provide timely comprehensive data on the human body for the entire life monitoring system." Nicole said, "After a long period of time, It was not until the end of the research that they fully recognized the importance of this kind of detection. This system can detect all kinds of abnormalities in each tested team member in a timely manner, even if it is a completely invisible clue.

"We are fortunate that with this instrument, I, as life science officer, and you, can do our job more conveniently. During the operation, you can avoid the routine scan checks that were previously planned. In up to 100 During the 1-day operation, the miniature lateral monitor only needs to be implanted once, at most twice, and does not need to be replaced." "How to solve the rejection reaction caused by a long time?" asked a doctor in the audience. "In the breakout session this afternoon, I will explain this in more detail," she replied. "For now, I can only explain briefly. The key to rejection is the change of four or five parameters, including acidity. Change. The outside of this micro-monitor is covered with a special chemical substance. This chemical substance is sampled from the implantation point of the human body, tested and analyzed, and then artificially synthesized. In other words, when the monitor is implanted Once in place, they will exhibit the same biochemical characteristics as other tissues. Those chemicals are slowly released from the monitor and seep out, forming a thin outer membrane on the outside, making them completely different from the surrounding biochemical characteristics. Consistent, so as to avoid rejection."

"Of course, I have already implanted this kind of thing in my body first." Nicole said, turning to face the holographic human blood circulation image, "A set of micro-monitors is injected from here, from the left arm, you see. These independent micro-monitors are guided to 32 different positions in the human body according to predetermined routes, and then they will be automatically embedded in the cells and tissues." When she said this, she saw many flickering light spots suddenly appeared in the holographic image, entering the body from the left arm and spreading to the whole body. Four enter the brain, three enter the heart, four enter the endocrine system, and the rest are distributed in various organs from the eyes to the toes.

"Each micro-monitor can sample and analyze those important physiological parameters through a set of microscopic sensors, and then store and record them; through the scanner, we can read out these data. In actual operation, I hope that every day Send out all your personal health data. Micro-monitors can store data for up to four days if needed." Nicole stopped, looked at everyone, and said, "If you have any questions, you can ask them .” "Okay, let me ask a question." Richard Walkerfield, sitting in the front row, said, "I think this system can collect tens of thousands of megabytes of data, which is very simple; the difficulty is how to Abnormal signals found in these data cannot be judged manually. I want to know how you do it."

"Your question hits the nail on the head, Richard," Nicole said with a smile, picking up a flat, rectangular object with many buttons on it. Data collected in different ways. We can display all the data at once, or read the data selectively, or even read only the data with warning marks..." Nicole saw that everyone was puzzled, so he said: "Okay, let me explain in more detail. All instruments have a reference 'standard value' when comparing data. Of course, due to everyone Individual differences, this value is not the same; at the same time, this value also allows a floating tolerance. When a measured value exceeds the range of this tolerance, it will generate a warning file and put a warning mark on the data .So, we can just read the data with these red flags. If an astronaut feels fine, I usually just look to see if there are red flags."

"However, if your measured value exceeds the specified value," Gallos interjected, "hey, you're welcome! This micro-monitor will activate its emergency transmitter, turn on its full power, and emit a terrible The sound of 'Wow, Wow...'. I have experienced how powerful it is. During a test, because the tolerance was not adjusted correctly, it screamed desperately. At that time, I thought: 'It's over, it's over, I'm going to die Already!'” Gallos was the team's deputy science officer, and his words caused a burst of laughter. "No instrument system is foolproof," continued Nicole, "so calibration data is especially important. We have carefully checked everyone's medical records and entered them into the system. However, only The accuracy of the data cannot be finalized until the micro-monitor is actually implanted. Today, we will implant the instrument; during the simulation training that starts on Tuesday, we will do a test run; and if necessary, we will update the standard value before the launch of the spacecraft .”

Everyone is a little apprehensive at the thought of embedding these weird things in the human body for a long time.Think about it, this thing is like a spy, entrenched in key places of your body, sending information, isn't it too scary? But General O'Toole's question was even more unsettling. "Nicole," he asked earnestly, "can you tell us how you can ensure that these things are placed exactly where they are intended and that they don't mess around in your body. More importantly, in case What if one fails?" "Of course, Michael," she replied politely, "I asked the same questions before putting these things in me. Simple, you don't leave the medical facility until you're sure you've put them in the right place." room."

Nicole looks to be about 35 years old, with bronze skin, dark brown almond eyes and thick black hair. Her face is always full of confidence and awe-inspiring arrogance.She continued: "From experience, one or two micromonitors do wander around, but it's easy to track them. After entering the correction command, they can be moved to the intended place. What to do if it fails? Experts Several different methods have been designed to solve it. First, each micrometer has a self-test program to check the voltage of the sensor, twenty times a day, and if a problem is found, the micrometer will immediately shut down. In addition, the micrometer Two very strict comprehensive self-inspections are also carried out. If the self-inspection fails, the preset program will be triggered, the chemical liquid will be secreted, dissolved and self-destructed, and finally absorbed by the body. This process has been confirmed by rigorous experiments. The body is completely harmless, so you don't have to worry."

Nicole finished her introduction and stood silently before her colleagues, watching them; no one said a word. "Any questions?" She asked after a while, a little awkwardly. "Well, whoever wants to do it first can stand next to the robot nurse. Be brave, everyone: I finished the implant last week." surgery, who will be next?" Frances stood up. "Okay! Let's start with the beauty Sabatini." Nicole said happily, and she gestured to the camera crew, "point the lens at this simulated image, and it will actually demonstrate these 'electronic bugs' swarming Great scene in Vessels."
