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

Chapter 1098 The legendary biodialysis machine of the natural department? !

Tumor lysis syndrome?
A large number of necrotic cells burst on the spot, and the cytoplasm is discharged into the body, increasing the load on the kidneys, leading to kidney failure?

In this case, Gretel hardly had to use his brain.There is a treatment that fits this symptom perfectly:

Let's have a dialysis!
Acute renal failure, come to dialysis!

Chronic renal failure, come to dialysis!

Acute drug poisoning, poison poisoning, in short, dialysis is all right!
Another name for hemodialysis is artificial kidney. Originally, this artificial kidney was used to carry everything for the real kidney!
Of course, dialyzers are not so easy to make.Semi-permeable membranes, dialysate, blood pumps, heparin pumps, and various control and monitoring equipment, each of which has a big barrier to overturn.

Of course, Gretel didn't expect that he could pass all the barriers by rubbing his hands.Just a semi-permeable membrane can make him die——

However, isn't Elder Fahim still here?

Legend!
A natural legend!

A person who has gone through a long period of time, a person who has seen a lot, has been stationed in the rich forest for many years, and has an extraordinary understanding of the rich species in the rainforest, the legend of the elf!

If in this world, the manufacture of bio-semipermeable membranes belongs to the profession of "bioalchemy", then Elder Fasim may be a figure at the academician level.

Apart from……

"What is a semipermeable membrane?"

"Uh……"

Gretel scratched his head, Gretel tangled, Gretel hesitated.

A semipermeable membrane is a membrane that only allows certain molecules and ions to diffuse in and out.Generally speaking, the semipermeable membrane only allows ions and small molecular substances to pass through, while biological macromolecules cannot pass through the semipermeable membrane freely.

The semi-permeable membrane used in hemodialysis machines only allows small molecules with a molecular weight below 1.5 and some middle molecular substances to pass through, while macromolecular substances with a molecular weight greater than 3.5 cannot pass through.

Therefore, proteins, bacteria, viruses, blood cells, these things cannot be separated out through the semi-permeable membrane...

——Great, first explain to Elder Fasim what a molecule is and what a molecular weight is.

"Uh...it's just a membrane, or a filter...big things can't get through, only small things can get through..."

"How big? How small?"

"This one……"

Grete felt from the bottom of his heart that the city's nine-year compulsory education, or 12-year basic education, is really very useful.

A person who has completed high school can basically understand what a semi-permeable membrane is without any effort.

——And here, even if Elder Fahim is a legendary master, he would have to rack his brains to explain it, starting from the most basic concepts...

He flipped through the papers, from atoms, to molecules, to ions.From the smallest potassium ions, sodium ions, and calcium ions, to large molecules, such as proteins...

Oh, what concentration, osmotic pressure, the same thing, you have to explain clearly.

Fortunately, as a former emergency doctor, he has a brilliant tongue, explaining the etiology and treatment methods to patients and their families who have not received complete basic education, which is a basic skill.

As he explained, he drew pictures and used metaphors for everything from overfertilizing plants and burning their roots, to hands wrinkling after soaking for too long.

As he talked, Elder Fahim's brows loosened a little bit:
"So that's how it is!——Isn't this the root of a plant? It absorbs water from the soil, absorbs what you said—nitrogen, phosphorus, and potassium—all kinds of things, and spreads from the root to the trunk, and then from the trunk to the branches and leaves..."

Gretel nodded vigorously.That's right, the epidermis of plant roots is equivalent to a semi-permeable membrane!Use the concentration difference of the solutions on both sides to absorb water into the plants...

Elder, it's great that you can understand!
"Since this is the case, I will discuss it with the plants... Let me think about it, who should I talk to..."

Gretel watched Elder Fahim get up and leave, shaking three times, and walked out of the laboratory.Wait, Elder Fahim, you want to discuss with the plants, what do you mean?
Do you want plants, even magic plants, to evolve on the spot and create a semi-permeable membrane for you?

Gretel was also very curious about what method a legendary master of the natural department would use to achieve this goal, so he couldn't help but chased him out.Without saying a word, follow behind to see:
Elder Fahim walked not too fast, but not too slow either.He stopped for a while and touched the grass on the ground, then turned around and touched a bush next to the shade.

Nodding, shaking his head, nodding again, shaking his head again, before he knew it, he walked into the depths of the jungle.

Gretel followed behind with one foot high and one foot low.Elder Fahim's walking speed seemed not fast, and he kept walking and stopping, but he followed for less than half an hour before he was out of breath and his steps became heavier and heavier.

Seeing that the elder had no intention of stopping at all, he turned into a black bear on the spot and ran up.Hey, fortunately, I learned Transfiguration from Ashe Moonsong, and walking in the forest in the form of a bear is really much more convenient...

Elder Fahim turned around and around.Hold down a tree, bow your head, meditate, and shake your head; grab another vine, bow your head, meditate, and shake your head again.Seeing that Gretel was following up, he smiled and waved to him:

"Grete, you really have a problem for me! Those plants that can grow semi-permeable membranes are either too big to be moved; or they are small. The filtration ability is too poor and the speed is too slow. Oh, trouble..."

Gretel: "...Hurr, snort, snort..."

If you bring up this topic, I'll just...

I have no common language with you...

"Oh, your Transfiguration, you can't maintain the animal form and talk at the same time? This is not good, it will cause serious trouble..."

Gretel: "Hurrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrs. times, year time but also times to be more

"Speaking of which, there was once an elf who wanted to find an animal companion, so she went to the forest to look for it. She saw a black bear with a tall figure and lustrous hair, and felt that it was very suitable for her vision, so she jumped up and rode on the bear's back. Want to tame it..."

Having said that, I already laughed out loud.Gretel looked at him inexplicably:
"Snoring?"

"Ah, this is a joke that has been circulating among elves for a long time. You haven't heard it. In fact, that black bear, who is a servant of nature, is wandering in the woods as a bear..."

Gretel: "..."

Elder, I always feel that what you are talking about is not suitable for young people to listen to!

He simply changed back to human form and walked to the elder.Standing on tiptoe, I looked around:
"Elder, if you want to find plants that meet the requirements, why don't you go to the pond? I remember that when Nevis was going to do the drinking water purification project, the members of the Natural Church gave birth to a group of aquatic plants... Theirs Filtration and purification are very strong..."

"Isn't this what I'm looking for..."

Two hours later, Gretel controlled a huge floating disc—not so much a floating disc, but rather a lotus vat—staggering, walking beside Elder Fahim.

The floating plate was filled with a small half tank of mud and a large tank of water, in which grew two cattails, a water lily, and some plants he didn't know very well.It was all communicated by Elder Fahim, and it was confirmed that it is generally suitable and can be used for hemodialysis:

"Gretel, you can't do this." Elder Fahim looked at Gretel with a look of hatred:
"Can't cast spells in bear form? This control is too weak. You must at least have a simple spellcasting ability! As a last resort, if you rush out of the encirclement with your teammates on your back, you must at least run while throwing healing spells and supporting yourself The ability of the barrier!"

Gretel's answer was to summon a phantom horse and get on the horse.

"Elder, I know, I will practice in the future..." He hummed with a bitter face:
"In the future, in the future! You see, I am a healer, I have so many things to study..."

The aquatic plants staggered and followed Gretel to the laboratory.Under Gretel's expectant eyes, a cattail plant sprouted and grew leaves, and a green stalk protruded out, stretching out to the edge of the experimental animal's cage...

"Come on, try it out."

The elder opened his mouth to command.Gretel was stunned:

"how to use?"

"Just use this tender stem! Insert it and see if it can filter..."

"...No, elder, wait a minute, where's the dialysate? I haven't prepared the dialysate yet!"

"Let it come with dialysate! Let's try it first..."

Gretel tried hard to turn his head, and two vines were born, which were respectively connected to the puncture needle.One pierced the artery, and the other end of the vine shook, and the cattail's tender stem immediately opened a hole and grew together with it;
Another grows with the other end of the cattail stalk, waiting for the blood to filter and gurgle out into a rabbit vein.One old and one young, plus Serila and Lin Ge, surrounded the rabbit, watching eagerly:

"...No. The blood cells can't flow through. Elder, the micropores inside the stalk must be bigger."

Elder Fahim shook his head and reached out to touch the cattails.A green light flashed, and the cattails seemed to change, but they didn't seem to change, but the vines leading to the veins did appear bright red.

"...No. It can't absorb the things you want."

This time, Elder Fahim shook his head by himself.He touched the cattail again, a green light flashed, the tender stem of the cattail suddenly became thicker, and liquid began to flow inside.

"No, the blood is starting to coagulate...Elder, can this cattail receive anti-coagulation spells? I don't know?...Then I'll give it a try first..."

Cattail, dialysis, failed.

Water lilies, dialysis, failure.

Duckweed, dialysis, failed.

Water hyacinth, dialysis, failure...

"No, these plants are too weak." After trying all the aquatic plants he could think of, Elder Fahim sat on the ground dejectedly, his white beard dripping wet:

"Plants that are too weak can't communicate with me well, and can't bear too many changes... I need stronger plants... I need high-level magic plants..."

"Then, Elder..." Gretel silently raised the oak stick in his hand:

"Is it okay to use it?"

"You are too weak." Elder Fahim turned his head after only one glance:

"It's too late today, and I'm tired. Get up early tomorrow, and I'll discuss it with Gu Shu..."

The next morning, Gretel watched in amazement as the old tree shook its branches, and a green twig grew out, which penetrated into the rabbit's abdomen.
