Chapter 206: The dwarf version of the ventilator is obtained!
Gretel coughed and vomited, rinsed his mouth and wiped his face. After struggling for a while, he regained consciousness and rushed back to the old dwarf. On the way, he did not forget to pick up a spoon to collect sputum and prepare to go back for bacterial culture experiments.
.
——The sputum entered his own mouth! Who knows what germs are in it! Mycobacterium tuberculosis? Streptococcus pneumoniae? Staphylococcus aureus? Or some mycoplasma? Chlamydia? Fungus?
Don't let him get infected!
Gretel hit himself with a healing spell with his backhand. He was worried after thinking about it, but it was another healing spell. His care for himself ended here: the old dwarf was obviously hypoxic just now, how is his recovery now, and does he need further treatment?
You have to confirm it with your own eyes before you can rest assured.
He rushed over all the way. Master Tarbot had already been helped up and was sitting on a stool sipping water. Two dwarf priests, one on the left and one on the right, accompanied the teacher. When he saw Gretel running over, he was thrown away.
Language】The priest immediately jumped up and made room for him:
"Hey, thank you so much just now!"
The old dwarf also stood up slowly while holding on to the table. Gretel quickly bent down to help him: "Master, let's sit outside? If you can't breathe smoothly, it's best not to sit inside. It's full of smoke..."
"No need, I'm fine like this." The old dwarf slowly raised a smile. Gretel was anxious: "Master!!!"
"Okay, okay, I listen to you." The old dwarf slowly patted the back of his hand. Once, twice. The corners of his eyes were slightly curved between his white beard and white hair. That smile was the same as when their mentor was seriously ill and his disciples begged him for treatment.
, exactly the same.
After patting twice, the old dwarf let go of Gretel and took the hands of the two disciples and walked out. A large group of dwarves followed in the tavern, carrying tables, moving chairs, lighting torches, and waiting for the old man to settle down on the hillside outside.
The refreshing mountain breeze blew in waves, and the tired face of the old dwarf gradually relaxed.
Gretel sat down in front of the old dwarf. Observing carefully, he saw that the old man's lips and fingernails were no longer blue, but his breathing was still rapid. The two dwarf priests looked on eagerly, being thrown away from [Language Proficiency].
The one came closer and asked carefully:
"Mr. Pastor, is there anything you can do to help the teacher? We have done everything we can..."
"Don't smoke, don't drink, breathe more fresh air, and don't sleep in a place with poor air circulation at night." Gretel looked at them seriously:
"And take some expectorant medicine regularly to help cough up phlegm. I am not good at medicine. I will write a letter to Elder Wood. You can take the letter to Oak Ridge and ask him for medicine. And..."
There is also oxygen! For respiratory failure secondary to chronic lung disease, respiratory failure caused by interstitial pulmonary fibrosis, etc., although oxygen therapy cannot cure the disease, it can effectively improve the patient's comfort and improve the oxygen box!
Gretel felt around in his pocket and took out his precious little test tube and the potassium permanganate in the test tube:
"Use the gas inside as a spell-casting material, gather the same type of gas together, and put it in a bubble spell to let people breathe. Who knows this spell - or divine spell?"
The two dwarves looked at each other. They looked at Grete with a blank expression, and Grete looked at them with a blank face, like another scumbag tutoring a scumbag to do a problem. Didn't I understand clearly... I obviously told Elder Wood to listen.
, he figured it out quickly, right?
"I can give it a try." Beside the long table, Elder Talbot coughed a few times and suddenly spoke. The two dwarf priests turned around in shock: "Teacher!"
The old dwarf waved his hand. He looked at Gretel seriously:
"But, how do I know that the magical technique is used correctly and that the gas gathered here is the one in the tube?"
"Yes!" The two dwarf priests nodded. The tube was empty, colorless and odorless. Even if it took half a day of effort, how would you know that the magic was used correctly? Without any proof, it always makes people confused...
"I have a solution for this." Grete thought for a while, continued to dig into his pocket, and took out a complete set of alchemy equipment from the space bag. He set it up on site, conducted experiments on site, and collected a tube of carbon dioxide on site:
"Try this?"
The old dwarf took the test tube and concentrated on performing magic to gather the gas in an empty beaker. After the spell was cast, Gretel lit a candle and poked it into the beaker. The candle flame did not waver, but a plume of black smoke came out.
, quietly extinguished.
"Yes, that's it!" Grete held his hand. He took out the earliest tube of potassium permanganate and heated it carefully to allow the potassium permanganate to decompose into oxygen. When the powder in the bottle changed from purple to gray-black, Grete added
He handed it to the old dwarf and told him earnestly:
"First release a bubble technique for yourself...Put the gas collected this time in the bubble technique and breathe by yourself!"
The old dwarf was doubtful. But looking at Grete's earnest eyes, he still raised his hand and tried the method for himself. Soon, his face turned rosy and he let out a long breath.
"How is it? Teacher, how is it?"
"much better……"
The old man's voice was brisk. Grete squatted next to him and quickly added:
"It's best to inhale this gas every day. - When you use a large magic spell and feel very tired and out of breath, or when you keep coughing and can't sleep at night, it's best to inhale it. I can't say it can cure it, but it can help.
People feel much more comfortable.”
The two dwarf priests nodded and almost clicked out the afterimages, one on the left and one on the right, grabbing Gretel and thanking him a thousand times. Gretel thought for a while:
"By the way, it's best not to use the bubble technique. It's too small and will be inhaled in a while, and the subsequent exhaust gas will be harmful to people. It's best to put a tube near the nose and connect a bellows behind it, one by one.
Click to inject the gas. As long as there is a dedicated person to inflate the bellows, the elderly can also inhale the gas when they are tired or asleep..."
He spread out his paper and pen, brushed and drew a schematic diagram of an oxygen tube and an oxygen pump. After drawing, he said:
"It is best not to use people to pull the bellows, as it is easy to over-ventilate. Get a mechanical transmission device at the back and use water or any force to push it... For example, get a water tank to release water, push the bellows and pull it... However, I will do this
It’s no longer possible…”
"We can do this!" Both dwarf priests laughed. "Making this kind of thing is our specialty!"
Grete pushed the pen and paper cleanly.
I give you paper and pen, Master, please draw!
A large group of dwarves started working at the same time, dividing the work and cooperating. Gretel was only responsible for calculating the tidal volume, the speed of pushing and pulling the bellows each time, and the air supply volume. He handed over the data and went straight to bed. Early the next morning, he saw something strange
The ventilator - or in other words, the oxygen supply bellows...
At the front is a tightly-fitting mask. According to Grete's requirements, two one-way valves were specially made to facilitate the discharge of exhaust gas. There is a rubber tube behind the mask. If the mask is removed, the tube can also be directly fixed in the patient's nostrils.
beside.
There is a bellows with a spring attached to the back of the pipe, and something similar to a waterwheel is constantly rotating beside it, pulling and pushing the bellows. And what pushes the waterwheel is a wine barrel with a faucet——
The wine barrel is filled with clean water, and the water level is always maintained at the highest point to ensure that the flow rate remains unchanged, the impact force remains unchanged, and the bellows can be pulled at a uniform speed. There is a taller and fatter wine barrel next to it, connected to the former through a siphon
, there was a dwarf standing nearby, pouring water into the tall wine barrel...
This... this is really a nice thing... at least it's semi-automatic...
Gretel's eyes shone and he smiled at the dwarf priest.
"This...can you make another one for me...I can use it to save other people..."
He took out his money bag. Before he could untie the string at the mouth of the bag, his palms were already firmly pressed:
"Why are you giving us money? You are our good brother. I can make something and ask for your money! Wait, I will make it for you tonight!"
yeah!!!
The dwarf version of the ventilator is available!
In the future, as long as you reach level 5, learn the oxygenation magic, or find a way to get a liquid oxygen tank, you can give people oxygen!
Great Brand Hospital, a powerful rescue tool, is available again!
