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

Chapter 600 Want to see the blood flow of the heart?Develop new magic, you pay

Gretel was not angry when the patient's family asked for more proof.

The right to know of patients or their family members is their due right.Otherwise, if you say that my child has a ventricular septal defect, is he a ventricular septal defect?

You say he has cervical erosion, but he still has cervical erosion!How many Pu-type hospitals and unscrupulous doctors deceive patients like this!
Moreover, ensuring patients' right to know can also improve compliance and thus improve treatment outcomes.Not to mention major surgery, when a nurse gives an injection, he must first explain to the patient what he is doing.

In his previous life, if he wasn't so busy that he couldn't fly, he would take the film, take the checklist, draw the schematic diagram of the operation, and explain it to the patient carefully...

Can't explain, explain clearly, that's the doctor's problem, not the patient's.

But, cardiovascular angiography...how on earth is this thing going to be done?
Cardiovascular angiography, the principle is actually very simple.It is nothing more than injecting a contrast agent into the blood vessel, letting it flow with the blood, and then turning on the X-ray.

The contrast agent is developed under X-ray, and at the same time, the process of developing the heart and blood vessel cavity is photographed by methods such as rapid filming, television photography or tape video.

However, for Gretel in this world, the difficulty is extremely high.Without him, without developer.

The contrast agent used for cardiovascular imaging in the previous life, such as diatrizoate meglumine, such as Uvism, iohexol, Omnipaque...

When the doctor writes a prescription, it can be picked up from the pharmacy, so there is no need to worry.But now, where can I find it?
hand rub?

Just kidding!
For example, non-ionic contrast agents for children, such as iohexol.

Its chemical name is 5-[acetyl(2-dihydroxypropyl)amino]-N,N'-bis(3-dihydroxypropyl)-2-triiodo -3-phthalamide...

If it was silver nitrate, silver ammonia solution, or iodine, Gretel rubbed it with his hands to see.With such a complex compound, he had only one idea:
Probably after becoming a legend, live another 500 years, the technology of this world can produce this stuff, right?
So Gretel had to find another way.Since he couldn't open the chest, let the patient's family members see the heart defect under direct vision;
The contract cannot be terminated with the snake, and the patient's family members can see the condition of the heart through the eyes of the snake;

Explain it to them with EKGs, X-rays and echocardiograms, and they don't understand...

So, use vines, or other methods, to send a secret magic eye into the heart, so that people can see what's going on in the heart?
Or, is there some other way?
Gretel thought hard for a long time, finally raised his brows, and looked at Viscount Alwyn who was sitting across from him.As soon as his expression changed, he obviously heard Viscount Alwyn let out a long breath...

Alas, poor parents in the world.Obviously she was really afraid of him, afraid that he would turn his back on him and not treat him, so he had to bite the bullet and ask...

Gretel tried his best to smile, making himself look amiable.He slowed down and said softly:
"The magic that shows the direction of blood flow in the heart, we don't have it yet. So, I think Mr. Ling's condition is okay. If you are willing to wait, I can try my best to study it, but—"

"Any conditions are fine! If you want money or someone, just say it!"

Viscount Alwin nodded repeatedly.The generous big hand patted his chest hard, making a dull sound of bang bang bang.

This man in his thirties has a straight waist and a military look in his gestures. He should look like a knight.However, there are strands of hair on the sideburns, but there are already gray hairs early.

... It is impossible to ask someone, and there is no one here who can help you.Money is really important, after all, a new research needs research funds no matter what...

Gretel smiled and spoke softly.Of course, the purpose is to try not to let the opponent jump up and run away:

"However, since this magic was developed solely for your needs, I'm afraid I have to ask you to bear the research funding."

"This……"

Viscount Alwyn's expression froze.Master Nordmark's request is absolutely reasonable in terms of reason:
After all, it was his own request to show the direction of blood flow in the heart, and the magician was willing to study spells for him, which had already given him great face.Which magician doesn't have more than a dozen or twenty items in his hands, and if you say you want to study them, they will jump in the line for you?

But afford research funding?Just kidding, that's the research of magicians!If it goes well, burning [-] to [-] gold coins is not a problem at all, isn't it going well?
If it doesn't go well, it will be a bottomless pit, filling his entire viscounty territory, and he doesn't know if it will be filled.

Gretel also saw his hesitation.He coughed lightly:
"Don't worry, I will try to reduce the research cost. In this way, I will not charge the cost of casting spells, and you only need to bear the cost of high-value consumables, is that okay? — If you are not at ease, you can also send personnel to supervise the use of consumables..."

Speaking of this, Viscount Alwyn really couldn't shirk anymore.He laughed and stood up:

"What did you say, the mage. You specialize in researching spells for us. I don't trust you anymore. What have I become? No supervision, the first research funding, I will pay 1000, no, 2000 gold coins first?"

It's nice to hang out with rich people.Two thousand gold coins, I don't know how much cost can be saved, which can be used to supplement the treatment expenses of the poor.

Gretel smiled brightly.

He retreated to the back building, rolled up his sleeves, and began to try angiography.Well, the first plan is to use the secret eye to try to enter the heart...

Take out the magic equipment, summon the arcane eye, adjust the size.The diameter is reduced from 1 inch to 1 cm, to 5 mm, to 3 mm...

I can't shrink anymore.He has already reached the limit, and if he wants to shrink again, he has to wait until he has reached level 7, learned the spell of the Mystic Eye, and the dismantling is successful.

And a diameter of 3 mm...Grete came out and walked around, looked at the rabbit in the cage, and shook his head:
This will definitely not pass through the radial vein of the rabbit, and it will burst in an instant.Going through the child's radial vein, or radial artery, doesn't seem like a good idea.

The first plan failed.Gretel made persistent efforts and tried the second solution:
Inject spell energy into the rabbit for development.

Medical common sense: You can use non-invasive inspection methods, but don’t use invasive inspection methods.If you can take medicine, you don’t need injections, if you can take intramuscular injections, you don’t need intravenous injections…

Every time you jump over a barrier, you will bring an exponentially rising risk.

He immobilized the rabbit with anesthesia, and then condensed a mass of healing energy and sent it into the rabbit's radial vein. In the meditation vision of [Detect Magic], the mass of energy entered the rabbit's body, immediately dispersed on the spot, and spread outward along the muscles and bones...

In the meditation field of vision, it seems that a small group of fireworks is lit up.As for running along the blood vessels and taking pictures of the blood vessels, sorry, they don’t exist.

Uh……

It seems, it seems, really can only inject magic potions...

Alright, here's the third plan.Gretel took a deep breath, and solemnly wrote down in the experiment record:

"Inject magic potion into the blood vessels of experimental animals, and then use [Detect Magic] to observe its flow route. The choice of magic potion must be reliable and cheap under the premise of ensuring safety—"

There are many types of potions in the wizarding world.Taking standard potions as an example, the cheapest first-tier potions, such as Leaping Potion and Spider Walking Potion, are sold in the trading hall of the White Tower all year round, and the price is stable at 50 gold coins;

Slightly more advanced potions, such as Insight Potion, Swimming Potion, and Stealth Potion, as long as there is no sudden and large demand, the price is stable at 150 gold coins.Adventurers buy them all year round, and there is an endless stream.

But Gretel didn't think about that at all.Most of the above potions are for drinking, and a small part is for smearing - if there is any problem, the gastrointestinal barrier is blocked.If you really want to inject it into muscle blood vessels, the safety is very worrying.

and so--

"Bring a bottle of [heal minor injuries] potion!"

A bottle of [Healing Minor Injuries] potion is also 50 gold coins, the average price.What?Treat minor injuries?

What kind of potion do you need for minor injuries? You can lick it yourself for a three- to four-centimeter cut, so you won't need to use healing techniques.Adventurers who work hard outside in the wind and rain are really not so precious.

Gretel did it himself, lined up a row of syringes, and sucked the medicine into the syringes. [Treatment of minor injuries] Potions are sold in standard bottles, one and a half inches high, and the thickness of a thumb.Potion content...

10 ml.

Aspirate 1 ml and inject it into the leg muscle of a rabbit. [Detect Magic] Can see magic images, but very blurry.

Draw another 1 ml and inject it into another rabbit.After five groups, no abnormalities were observed, and another 2.5 ml was drawn and injected into the leg muscles of the sixth rabbit...

Well, the 1ml version makes 5 and the 2.5ml version makes 6.

After 11 rabbits were finished, they were observed for 1 hour, and there was no abnormality, and the increase in invasive blood pressure was within the normal range.Passed the first pass of the safety test, and the validity test is temporarily in doubt.

100 gold coins, soaring with wings.

Gretel compared the weight of the rabbit and the little boy, and felt that 2.5 milliliters should be about the same—anyway, the contrast agent used for pediatric cardiovascular angiography is only tens of milliliters.He geared up and started to do the next step:
Draw 1ml of [Treatment of Minor Injuries] potion and inject it into the lower end of the rabbit's femoral artery...

[Detect Magic] When it falls, the images of magic energy light up slightly along the blood vessels.It hadn't flowed halfway through the pretibial artery, and it was so sad that it was too faint to see.

It's okay, as long as you can see it.Grete made persistent efforts and did 5 sets of 1ml version in a row, and then 6 sets of 2.5ml version in a row.The conclusion is that the safety is acceptable, but the contrast effect is not good.

The magic energy content is too little, 2.5ml of healing potion, the pretibial artery can't be seen if it doesn't run out.

The second one is 100 gold coins, soaring with wings.

So should I increase the push pressure, or switch to a better healing potion? [Treat moderate injuries] Potion, 300 gold coins per bottle...

For the sake of money, Gretel decided to check the safety of angiography first.He took the fifth bottle of [Healing Minor Injuries] potion, and directly used the vine to go up the blood vessel and lead to the rabbit's heart.

One, two, three, potion injection, start!
The experiment has just started, and the 250 gold coins have been burned away.

Magic research is so expensive.Fortunately, the benefactor paid the bill, otherwise...

My body finally got better, and I was sure that the fever had passed, except for a little cough.Now continue and add more...

Ask for subscription, ask for monthly pass, ask for recommendation ticket, ask for book review, ask for various...
