Chapter 182: The birth of a medical catheter? A long way to go
Grete is very satisfied with his research direction.
In medicine, there are too many places where various tubes are used. Those used from above include nasogastric tubes, gastric tubes, tracheal intubations, gastroscopes, and fiberoptic bronchoscopes; those used from below include urethral catheters, anal canals, and gastroscopes.
Scope; inserted into the wound, such as drainage tubes placed during various wound healing periods, such as drainage tubes after thoracotomy and abdominal puncture...
Another example is infusion catheters, hemodialysis catheters, angiography catheters, catheters for interventional therapy...
In the past, Grete didn't have silicone, latex, or medical plastic, so he couldn't make any kind of tubes. Now that he has mastered the skills of plant growth, he can even rub it with his own hands!
In my mind, a large area of the "available" part of the healing skill tree lit up...
Although he is still not good at infusions, mainly because he cannot produce liquids that are pure enough to ensure sterility, but when the patient is suffocated and needs a tracheal intubation, or is unconscious and unable to eat, he needs a nasogastric tube.
It’s no longer difficult for him!
Gretel's eyes were bright and full of excitement, and he smiled happily at Elder Wood. Elder Wood looked at him confused:
"...What on earth did you give birth to?"
He looked down at the vine again. If Gretel only produced a hollow tube, he wouldn't be so surprised. After all, he had induced labor twice before. One was inserted into the stomach, and the other was simply inserted into the intestines.
They all played a role that cannot be ignored, and the second effect was particularly immediate. The question is, what is this in Grete’s hand?
The overall thickness is uniform, and the diameter is about half the diameter of the little fingernail. The end held in the hand is forked, and the two ends after the fork are extremely swollen. The length and thickness are almost the same as the little finger.
A round ball swelled out near the end of the other end. Moving forward, the top did not open, but was closed into a round drop shape. On the contrary, two symmetrical holes were opened near the end, about the length of a fingernail.
, rice grain shape, can be seen from one side to the other without difficulty.
Elder Wood thought about it, but couldn't figure out what it was. Looking at Grete again, he had raised the tube in his hand to his mouth, pinched the end of the branched "Y" shape, and directed it to the other branch.
Blow hard...
After blowing and blowing, the slightly deflated ball bulged up little by little, and then exploded with a "pop" sound...
Exploded...
"How old are you for blowing up balloons?"
Elder Wood shook his head.
Gretel lowered his arms in annoyance and pursed his lips.
At first, he wanted to make the simplest ordinary single-lumen urinary catheter. As he was doing it, he decided to challenge his control and made a double-lumen single-balloon urinary catheter.
Looking at it now, I can see that it was created, but the air bag was not strong enough and it exploded before being inflated much...
This is not possible! The material is not strong enough. If it explodes during clinical application, he will not dare to think about the troubles that will follow...
Gretel touched the vine in his hand again. The fingertips felt prickly and not smooth enough. Not to mention not as good as silicone rubber and natural latex, even the most basic PVC pipe couldn't keep up. This thing can't be used.
The foreign body feeling is too strong...
"Elder, why did this vine grow...is it hairy on the outside?"
"The grass seeds you used have hairy stems on them!"
Elder Wood looked at him speechlessly. How did this child learn common sense? Knowing plants, observing animals, and understanding nature are all basic lessons. Servers of the God of Nature are already familiar with them before becoming a priest's apprentice. Why?
Are you a level 2 priest and haven’t started yet?
Can’t recognize the type of grass seeds?
"Then...what should I do if I want it to be smoother?"
"Change seeds!"
Elder Wood took Gretel into the back room and stood in front of a large cabinet. The design of the cabinet was exactly the same as the cabinet in the magic materials store - that is to say, it was exactly the same as the medicine cabinet in the Chinese medicine store. Elder Wood casually opened a cabinet
When Grete stretched out his head to look at the drawer, he felt dizzy.
The drawer is seven to eight inches wide, three to four inches high, and more than a foot deep. There are three compartments in the pharmacy. Elder Wood has about ten compartments here. There are plant seeds lying in each compartment. If you glance over, there is no duplicate.
…
Some are scattered about seven or eight, and some are piled up to the point where they are about to stand out on the grid;
There are those that are as big as the tip of a pin and can fly when you blow a breath, and there are those that are as big as a soybean, or even the size of a thumb;
Some have smooth surfaces, some have pitted surfaces, and some have fluff or even pods;
Some are dark black, some are black and white, and some are colorful and green...
To make matters worse, there are no labels.
Not a piece of paper.
"Elder..." Grete's face turned pale. He opened a drawer, but he didn't recognize it. He opened another drawer, but he still didn't recognize it. At least there was something he recognized in the third drawer, it should be an acorn, "Ice Age"
"There is a strong sense of presence in that animated movie; in the fourth drawer, I don't recognize anything...
I major in clinical medicine! Not in agricultural botany!
Such a big cabinet has 56 drawers spread across the board, and it is conservatively estimated to have several hundred grids, each grid contains a type of seed...
"Elder...these seeds...which one is which? Why aren't they even named?"
"No need to stick it! You can ask it yourself! Only if you can communicate can you use it. If you can't communicate, it's useless if you take it!"
Gretel: "..."Can't communicate...
If you can't communicate, just try the same thing. Grete looked at Elder Wood helplessly, and Elder Wood gestured to him, indicating "take it as you like." Take it as you like? Currently, it is spawned once, and it consumes about the same as a second-level spell, one day.
After trying five times, maybe... a hundred days, you're done trying?
One hundred days is one hundred days! Gretel suddenly felt proud. He asked the barbarian to drag over his backpack, without any courtesy, take ten seeds from this grid and eight seeds from that grid. There are more seeds in this grid, so grab one.
A lot of...
"You just use this bag to carry things?"
The old magician suddenly walked in. He glanced at the backpack in Gretel's hand, and his face was full of words: it was half a person tall, made of leather and coarse cloth, and attached to a thick belt. Because it was often put down on the ground, the appearance
It's a bit dirty. In short, ordinary adventurers and warriors, rangers can still see it if they carry it, mages carry it...
It really ruins the image.
"Well, I usually don't carry this thing on my back..." This backpack was designed by Grete himself, imitating the structure of a mountaineering bag. It is carried by a barbarian during a short trip, and when it comes to a long trip, the barbarian needs to carry a big bag, so he
I can also recite:
"I usually use this fanny pack..."
"How much can such a small pocket carry?" Master Tolga raised his eyebrows again. Before Grete could protest, he waved his sleeves and fluttered a small cloth bag:
