It's not that hard to open a hospital in another world, right?

Chapter 209 The dwarf version of the ventilator is here!
Gretel coughed and vomited, rinsed his mouth and wiped his face. After tossing for a while, he recovered and rushed back to the old dwarf.On the way, I did not forget to pick up a spoon to collect the sputum, and prepare to go back to do the bacterial culture experiment.

——The phlegm entered his own mouth!Who knows what germs are in there!Mycobacterium tuberculosis?Streptococcus pneumoniae?staphylococcus?Or what mycoplasma?Chlamydia?fungus?
Don't get infected!

Gretel threw himself a healing technique with a backhand, thinking about it, it was another healing technique.His concern for himself ended here: the old dwarf was obviously hypoxic just now, how he is recovering now, and whether he needs further treatment, he has to confirm with his own eyes before he can rest assured.

As he rushed all the way, Master Tarbert had already been helped up and was sitting on a stool drinking water. Two dwarf priests, one on the left and the other on the right, accompanied the teacher.Seeing Gretel rushing over, the priest who had been thrown [Language Proficiency] immediately jumped up to make room for him:
"Hey, thank you just now!"

The old dwarf also supported the table and got up slowly.Gretel quickly bent down to help him: "Master, let's sit outside? If you can't breathe well, it's best not to sit inside, it's smoky..."

"No need, I'm fine like this." The old dwarf slowly raised a smile.Gretel panicked: "Master!!!"

"Okay, okay, I'll listen to you." The old dwarf patted the back of his hand slowly.Once, twice.With white beard and white hair, the corners of the eyes were slightly curved, and the smile was exactly the same as when their mentor was seriously ill and the disciples begged for treatment.

After clapping twice, the old dwarf let go of Gretel, and walked out holding the hands of the two disciples.A large group of dwarves in the tavern followed, carrying tables and chairs, lighting torches, and waiting for the old man to settle down on the hillside outside.The refreshing mountain wind blew in waves, and the tired face of the old dwarf gradually relaxed.

Gretel sat down in front of the old dwarf.Observing carefully, the old man's lips and fingernails were no longer bruised, but his breathing was still short.The two dwarf priests watched eagerly, and the one who had been thrown [Language] moved closer and asked cautiously:

"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 no ventilation at night." Gretel looked at them seriously:
"And take some phlegm medicine regularly to help cough up phlegm. I'm not good at medicine. I'll write a letter to Elder Wood. Take the letter to Oak Ridge and ask him for medicine. And there is..."

There is oxygen!For respiratory failure secondary to chronic lung disease and pulmonary interstitial fibrosis, although oxygen therapy cannot cure the disease, it can effectively improve patient comfort and oxygenation!
Gretel fumbled in his fanny pack, and took out his precious little test tube, and the potassium permanganate in the test tube:
"Use the gas inside here as a spell-casting material, gather the same kind of gas together, and put it in the bubble technique to let people breathe. Who will do this spell—or divine spell?"

The two dwarves looked at each other.They stared at Gretel with blank faces, and Gretel looked at them with blank faces, like another scumbag tutoring a scumbag with a problem.Is it because I didn't explain it clearly... When I explained it to Elder Wood, he figured it out quickly, didn't he?
"I can give it a try." Elder Talbert coughed softly at the edge of the long table and suddenly spoke.The two dwarf priests turned their heads 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 the gas gathered is the one in the pipe?"

"Yes!" The two dwarf priests nodded their heads.The tube is empty, colorless and odorless, even if you use half a day's strength, how do you know that you have used the magic spell correctly?Can't see the proof, always makes people feel at a loss...

"I have a solution for this." Gretel thought for a while, then continued to rummage through his pockets, and took out a complete set of alchemy equipment from the interspatial bag.On-site erection, on-site experiments, and a tube of carbon dioxide collected on site:
"Try this?"

The old dwarf took the test tube and concentrated on performing the magic, collecting the gas in an empty beaker.After casting the spell, Gretel lit a candle and poked it into the beaker. The candle flame didn't flicker, and a plume of black smoke rose, which was quietly extinguished.

"That's right, this is it!" Gretel clapped his hands.He dug out the earliest tube of potassium permanganate and heated it carefully to let the potassium permanganate decompose to produce oxygen.When the powder in the bottle turned from purple to gray-black, Gretel handed it to the old dwarf, and instructed earnestly:

"You release a bubble technique for yourself first... the gas collected this time, put it in the bubble technique, and breathe by yourself!"

The old dwarf was dubious.But looking at Gretel's earnest gaze, he still raised his hand and tried a trick 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.Gretel squatted beside him and hurriedly added:

"It's best to inhale this gas every day. ——When you feel very tired and breathless after using a large magic spell, or when you cough and can't sleep at night, you'd better inhale it. I can't say it's cured, but it can People are much more comfortable.”

The two dwarf priests nodded and were about to point out afterimages, one on the left and one on the right, grabbing Gretel and thanking him very much.Gretel thought for a while:
"By the way, it's best not to use air bubbles. It's too small, and it will be sucked out in a while, and the exhaust gas that follows will be harmful to people. It's better to put a tube near the nose, with a bellows behind it, and blow it out one by one. Beat the gas. As long as there is a special person to inflate the bellows, the old man can also breathe this gas when he is tired or asleep..."

He spread out a pen and paper, brushed, and drew a schematic diagram of an oxygen tube and an oxygen pump.After drawing, he said:
"It's best not to pull the bellows by people, because it's easy to over-ventilate. Put a mechanical transmission device behind it, and push it with water power, or any force... For example, get a water tank to fill the water, push the bellows to pump and pull... But, this is what I want I can't..."

"We can do this!" Both dwarf priests laughed. "It's our specialty to make stuff like this!"

Gretel simply pushed the pen and paper away.

Pen and paper for you, God, please draw!

A large group of dwarves worked at the same time, dividing labor and cooperating.Gretel is only responsible for calculating the tidal volume, the speed at which the bellows are pushed and pulled each time, and the volume of air supplied.As soon as he handed in the data, he went straight to sleep. Early the next morning, he saw a strange-looking ventilator—or, in other words, an oxygen bellows...

At the front is a tightly fitting mask. According to Gretel's request, two one-way valves are specially made to facilitate the exhaust gas.A gum tube is attached to the back of the mask. If the mask is removed, the tube can also be fixed directly next to the patient's nostrils.

A bellows with a spring is attached to the back of the pipe, and a thing like a waterwheel keeps turning beside it, pulling and pushing the bellows.But what drives the waterwheel is a wine barrel with a tap——

The wine barrel is filled with clear water, and the water level is always maintained at the highest point, so as to ensure that the flow rate and impact force remain unchanged, and the bellows can be pulled at a constant speed.A taller and fatter wine barrel was poked next to it, connected to the former through a siphon, and a dwarf stood beside it, pouring water into the tall wine barrel...

This... this is really a nice thing... at least semi-automatic...

Gretel's eyes lit up, 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 purse.Before pulling off the rope at the mouth of the bag, the palm of your hand has been firmly pressed:

"Why do you give money! You are our good brother, if you make something, you can still ask for your money! Wait, I will do it for you tonight!"

yeah! ! !
The dwarf version of the ventilator is here!
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 inhale oxygen!

The Great Hospital, the first-aid weapon, is here again!
