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

Chapter 524 We are not the race that understands blood best

Is the oxygenated version of arterial blood delicious?

That's good.

Amid Viscount Sebesh's endless surprises, Gretel packed up the test tube and smiled slightly:
"So, is this little trick enough to convince your Excellency the Marquis to let him participate in the research and development?"

"It's definitely not enough!" Viscount Sebesh raised half a beaker of blood to the tip of his nose, sniffed it carefully, and then rubbed it carefully with the tip of his tongue:
"The processed blood does taste better, but it's still incomparable with fresh arterial blood! It's sour and has a bad taste~~~"

Oh, that's definitely different.What is carried in the venous blood is the waste of human metabolism, carbon dioxide, excess electrolytes, and various things.Arterial blood carries oxygen and nutrients.

Therefore, the extracorporeal circulation device needs to use a semi-permeable membrane or something to allow oxygen to enter and carbon dioxide to exit, and to filter out uric acid by the way. If you ask me to do it now, I can’t do it~~~
Gretel was unflappable.Uric acid, carbon dioxide, electrolytes, and various ions are all dissolved in blood plasma.If we can't make a semi-permeable membrane, let's separate it and it's over!

"If you think it tastes bad, I have another way. Do you want to try it?"

"want!"

"Okay, go to the hospital!"

There are centrifuges in the hospital.The anticoagulated blood was spun in the centrifuge, buzzing, and one end of blood cells and one end of plasma were perfectly separated.

What kind of stem cells, lymphocytes, white blood cells, platelets, etc., Gretel will not separate them, and release all the blood cells. According to the specific volume, Ringer's solution-that is, normal saline, add potassium chloride and calcium chloride in proportion ——He fell inward with a clatter.

Stir well and centrifuge once to wash away the residual plasma.Then, add Ringer's solution according to the standard hematocrit.

Anyway, in clinical blood transfusion, Ringer's solution is also used to mix blood cells, hum.Then, gurgle and bleed oxygen into it, and process the color into bright red.

"Come on, try-"

Viscount Sebesh accepted it dubiously.Hold it in your hand, shake it gently, and observe the color depth and clarity of the cup of blood, whether there is a hanging cup, whether there are any bubbles...

"Drinking blood from a beaker always feels weird. Can I have a goblet next time?"

no.Gretel rolled his eyes at him.I see you taste your blood in the same posture as tasting wine, I also find it weird!
Viscount Sebesh shook enough blood, brought it to his face, and took a deep sniff.The nasal cavity dilates, trying to draw in the gas molecules above the beaker:
"No smell?"

He frowned, sniffed again in disbelief, and sniffed again, heartbroken, and took a big gulp.Then, turning to Gretel, heartbroken:

"Master Nordmark, you are such a waste! Why is there no flavor at all, bland—like, like—"

"Alcohol?"

Gretel helped him make up a word.Viscount Sebesh looked at him blankly, Gretel turned around and poured a few milliliters of alcohol, and handed him a taste.Mr. Viscount drank it down and nodded vigorously:
"That's right! That's it! It's still the same thing, but it's tasteless! How did you do it! You ruined such a good taste!"

That's for sure.Gretel spread his hands.

It's like distilling alcohol from wine.Those complex aromatic substances - the ingredients that make up the flavor, what esters, what fusel oils, are all left in place.A sip of boredom is like drinking a sip of burning water, taste?what is that?
As for the ingredients that the blood race considers to be flavors, Gretel estimates that most of them are thyroxine, adrenaline, androgen, estrogen, etc., and they are all dissolved in the blood plasma.

The blood cells are separated, rinsed, and all plasma is removed.Then, add the Ringer's solution in proportion...

I'm sorry, it must be bland, and the smell is gone.This is not as good as high-purity vodka, at least it is still strong.

But it's still drinkable.Viscount Sebesh took a sip, took a sip of blood cherishingly, and frowned:
"It's still drinkable, um, it's not comparable to fresh human blood, but it's not bad. You don't know, sometimes when you go out, you don't have blood slaves with you, and you can't find a good hunting target. The blood you suck That stinks..."

Gretel: ...Thanks, I don't want to hear, I don't want to know at all.Can you not tell me your 180 feelings about hunting and blood sucking?
Obviously not.Viscount Sebesh muttered, chattered, drank a sip of blood, and said a few words.After finally pouring, he suddenly let out a long sigh and squatted on the ground like a potato.

Gretel: "...what's the matter?"

"I haven't thought about these practices... I don't understand why it is done like this..." Viscount Sebesh hugged his head and groaned:

"We are not the race that understands blood best..."

... What is so proud of this false name?
Gretel didn't understand at all.However, this did not prevent him from taking advantage of the fire:

"So do you want to participate in my research? - Participate, the research is successful, you are still the race that understands blood best! First author, I will add you!"

"it is good!"

Potatoes germinate, draw strips, and grow taller.Viscount Sebesh jumped up again, gearing up:
"Where do we start?"

Start by verifying your blood type.In other words, start by verifying that the blood family also has blood types.Gretel is still a little sure about this: the vampires, even though they are undead creatures, were once human.Since they are human beings, then, probably, maybe, maybe, they also have blood types?
What's more, they still have rejection reactions.This is also a validation, isn't it?
Viscount Sebesh wrinkled his face and stretched out his right hand.Muttering, chanting non-stop:

"It's a loss, it's a loss, why did you ask you to draw my blood... If I had known that I would do this today, I would bring a descendant here, and it would be over if I let you draw his blood... Hey! Take it easy!"

"I'm already light enough..." Gretel was expressionless, pressing left and right on the inside of his right elbow, right and left.It's not that I want to use force, why is your brachial vein so deflated, it's hard to press it!
Fortunately, his craftsmanship has never been left behind.Emergency first aid, opening of intravenous access and so on, you have to do it when you are in a hurry, you can't always wait for the nurses to do it.After pressing for a while, I finally got the position right, and a needle was inserted into the vein.

then.

then.

Gretel looked at the syringe, at the liquid gurgling out of the syringe, and then at Viscount Sebesh.Your blood is wrong!
Why is the color of the liquid drawn from the blood vessels so light?
Among the patients I have treated, the hemoglobin dropped to 30g/l, which is not so weak!Are you sending me a drop of blood mixed with 5 milliliters of normal saline?
Under his puzzled and accusing gaze, Viscount Sebesh turned his head pale with a pale face:

"What are you looking at me for?—The true blood of the blood race is not so easy to get! Give me some time!"
