Chapter 493 Blood Pressure Monitor, Make a Magic Version! (Bugfield Leader Adds 8 Updates)
Trapping the spy was a success!
With a pet peeve out of the way, Grete was able to happily continue visiting the booth. He took out a large amount of gold coins, packed up half a ton of rubber balls (and set a target for one ton of rubber for the coming year), and bought a whole cart of branches, leaves, flowers, plants, and various animals:
branches with small clusters of white flowers, soft leaves, and gray bark stripped from the trees, which the natives are said to have used to cure swamp fever;
The slurry extracted from the brightly colored frogs can paralyze and paralyze people;
Palm-long, fist-thick, brown fruit as hard as wood, with a bunch of bean-shaped seeds clustered inside;
There is also a brown flower that is regarded as a "sacred flower" by the natives of the New World and can rotate around the sun...
Of course, in the end, Grete asked the Archmage to help him find the owner of the long skirt and asked if he could let Cerela try on the skirt - if the size was right, it would be best if he could buy it.
When he asked what kind of decoration the skirt was made of, the seller responded readily:
"Jade bug! - Oh, that is a local bug, very beautiful, known as the 'rainbow eyes'. This skirt is decorated with its elytra. It is said to be a princess's wedding dress, three hundred A female worker worked for a whole year..."
"Ah! Take it away! Take it away!"
Miss Silver Dragon jumped back reflexively. Such a beautiful decoration is actually an insect carapace! That little, dirty thing!
Think about the feeling of wearing a skirt, as if your whole body is crawling with bugs, and your whole body is not good!
Although she is not afraid of this thing - these bugs can't hurt her, at best it's just a breath of dragon's breath - but it's so disgusting!
She jumped out so fast that she knocked over the tea tray in front of her, causing tea to flow all over the table. Serila ignored it, turned around and ran away. Gretel smiled apologetically and spread his palms. The seller smiled understandingly:
"Ah, that's normal, young lady—"
The two parties shook hands, exchanged contact information, and agreed to visit frequently in the future before ending the exhibition. After leaving the exhibition hall, Grete did not return to the hospital, but rushed to the Mage Tower in a hurry:
"Mr. Norwood! Mr. Norwood! Please do me a favor!"
Mr. Norwood emerged from the laboratory. This magician of the transformation system, following Gretel, his fortunes turned around and he successfully passed the level and advanced to the fifth level mage. Currently he is very high-spirited, leading two apprentices to study hard, and is heading towards the sixth level.
After staying in the Master's Tower for nearly a year, the gray hair on his temples has become less, his waist is straighter, he walks brisker, and his voice is louder. When he looked at Gretel, his eyes were bright and full of enthusiasm:
"Mr. Nordmark? What's the matter?"
The boss has summoned!
There’s a new topic!
You can publish papers again!
Master Nordmark is very generous. For the topics he throws out, he will assign at most one corresponding author, and maybe not even the corresponding author...
"Look at these rubbers!" Gretel summoned two mage hands, enlarged and bold versions, and held them together. He patted the space bag and poured out a handful of rubber balls:
"Please help me, treat them with sulfur and make them into airbags - about the size of an airbag that can be held in one hand, connected to a tube, and then connected to a long, thin airbag..."
Grete wrote and wrote, and told Master Norwood the general structure of the inflatable parts of the old mercury sphygmomanometer. Master Norwood squeezed the rubber ball and nodded:
"I know that sulfur treatment is used, and "The Philosopher's Stone" has published relevant papers. Unfortunately, the things made are bulky, and the long tubes and thin sheets are a bit troublesome. What you want, boss, needs further research. When do you want it, boss? "
"The sooner the better... uh..."
Gretel's voice became smaller and smaller. Although he is not engaged in materials science, he also knows that the four major sinkholes of biochemical environmental materials cannot be easily achieved. Researchers need to work hard, and bosses need to be more patient.
Relying on a transformation mage and leading two apprentices, if you want to put forward demands today and get results tomorrow, wake up, the requirements are too high.
"It doesn't matter, I'll try a few more sets." Master Norwood took up the task considerately:
"Boss, is it enough to just use sulfur? Do you need to use anything else? How much sulfur do you need to add? You saw the archmages processing it at that time. How did it be done? Does it need to be heated?"
Gretel almost ran away. When he was in the dwarf kingdom, he was responsible for coming up with ideas, and the Archmage of the Change Department was responsible for handling them. He actually watched the process. Basically, sulfur flew up, rubber balls flew up, and they were kneaded, fused, and stretched by an invisible hand...
Then there was nothing more. Then, all the gaskets, sealing rings, and various other things that Grete needed were made. What kind of temperature control and what kind of material ratio does not exist.
Grete had to find a way on his own. He counted them one by one with his fingers:
“You don’t have to use only sulfur, you can try all kinds of sulfur compounds;”
"The dosage of sulfur...you can try it from 1% to 40%. Different dosages seem to produce different rubber;"
"Temperature... it can also be immersed in a sulfide solution, vulcanized at room temperature, or hot vulcanized... I don't know the specific temperature, but you can try it in hot water, steam, or hot air; "
"You can also try adding something else, for example, the nitrocellulose I made some time ago..."
I understand, the boss has an idea and is not sure how to achieve the effect. As for the operational ability, let alone talking about it. Master Norwood nodded, took the bag of rubber, shook off the draft paper, and drew a grid of Boss Boss:
"Go check the papers first!" he shouted to his two apprentices:
"Angela, go check the paper! Berry, go buy all the rubber products on the market! Speed up!"
The two apprentices agreed. One ran out of the mage tower, summoned a magic horse, and rushed to the trading hall of the White Tower; the other ran to the information center of the mage tower, went to find Mr. MOSS, and looked through the list of papers.
Mr. Norwood himself raised his rough, calloused palms that were no longer cracked and began to scratch his head:
Hey, how many combinations are there of different compounds, different dosages, different ratios, and different temperatures... at least thousands, right?
I don’t know if the boss will agree to recruit a few more apprentices...
No, the boss will definitely agree. The boss doesn’t care about this. The key is whether Mr. Lin En will agree and whether the income of the Mage Tower can sustain it.
You know, cultivating a transformation magician is just a matter of piles of materials!
Mr. Norwood rolled up his sleeves and began to make an experiment plan, make a list of materials, gather the experimental equipment, and prepare to work. Serila followed curiously and walked in, looking left and right. For a long time he couldn't figure out the reason, so he turned back and asked Gretel:
"Gretel, what did you ask him to do? What...is this thing for?"
She carried the decomposed drawing of the design and swiped it, making a lot of noise. Gretel has come up with something new again! After throwing myself in the hospital and crawling alone on the top of a mountain for so long, I finally found something new!
"This... Oh, blood pressure monitor." Grete was concentrating on cutting open the chest wall of a dog, and after a while he glanced back. Absently, he threw out a name and returned his attention to the operation:
All blood samples are placed in the Tower of Sleeplessness. He didn't want to draw blood one by one in his mage tower, try to cross-match blood to test blood types, and then use [Identify Bloodline] to draw signal diagrams. I had no choice but to pick up half of the experiments I had done when I was in the hospital and do them:
Creation of a model of patent ductus arteriosus in dogs.
Thanks to the rabies research institute, the council captured a lot of rabid dogs for him. Naturally, they also caught a bunch of normal stray dogs. As the owner of the hospital and the leader of the project, Grete used two dogs to make animal models. That was not a problem at all.
Unfortunately, all previous experiments failed.
Hope it works this time. Grete's men steadily cut open the dog's skin, subcutaneous tissue, and muscles, used a thoracotomy to open the ribs, cut the upper pericardium along the vagus nerve, and exposed the pulmonary artery...
Serira looked on beside her and didn't dare to breathe. She automatically stood farther away and put on a mask on herself. After a while, I saw that Gretel had finished separating the two blood vessels, stopped to take a rest, and quickly raced against time to ask:
"What is blood pressure?"
"It's just the pressure of the blood." Grete stared at the yellow dog's jugular vein that had been separated and exposed, thinking about how long to cut it. After hearing Cerrela's question, he pointed to the descending aorta that had been exposed after the mediastinal pleural wall was violently cut open:
"When the heart beats, it puts a lot of pressure on the blood and shoots it into the arteries. The arteries contract step by step to provide pressure, so that the blood can be sent to all parts of the body. I made this thing to measure the pressure of the blood. .”
Cerela popped up a secret eye and stared at the slightly beating blood vessels, looking curious and nervous at the same time. Grete pointed to that section of artery:
"If you insert a tube into it and connect it to an upright glass tube, you will see the blood keep going up - the higher it goes, it means how high the blood pressure is. But in that case, you might A glass tube two to three meters high is needed..."
Grete's lips curved into a smile. A blood pressure of 130 mm of mercury is approximately equal to 1767 mm of water, which is 1.7 meters. If unfortunately, the patient's blood pressure reaches 230 mmHg, then the glass tube needs to be more than 3 meters high.
Such a tall glass tube is not troublesome at all - if the glass tube is thin, it is possible to suck blood up through capillary action alone; if it is thicker, for example, a tube with a diameter of 1 square centimeter, one stroke can be 170 ml or even 300ml. With so much blood rushing out, how can it be stuffed back into the blood vessels?
...Speaking of which, the doctor who first measured the animal's blood pressure drew 270 centimeters of blood from the horse's carotid artery. Did he get it back in the end?
"If you don't want such a tall glass tube, you have to use a U-shaped tube and put mercury on the other end. But mercury is troublesome and highly toxic. It's best not to use invasive ones..."
"Then, why can't we use magic?"
Gretel was stunned. Serira pointed at the beating blood vessel, and pressed down gently with her white fingertips, as if pressing on a column of blood spurting out of nothingness, feeling its pressure:
"Can you use a tube and insert it directly into the blood vessel, and connect the other end to the magic array - the amount of pressure it receives will be directly displayed by the magic array?"
Gretel:? ? ?
Very good, girl, are you a self-taught person and can you directly come up with invasive blood pressure monitoring?
It's a good idea. I'll ask later if there is a magic circle that directly displays pressure...
