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

Chapter 406 Insert the vine into the heart!
One click, two clicks, three clicks.Extremely slight, almost imperceptible to the naked eye.If it wasn't for the fact that the ammeter was placed on the floating plate, it wouldn't be shaken by the carriage at all. Grete could almost believe that the pointer was shaken wildly.

However, this kind of shaking is also rare.Soon, the ammeter pointer—

Not moving.

"Wow, why didn't you move?"

"Not dead? Are you still angry?"

Two pairs of probing eyes looked at Gretel.Gretel shook his head helplessly:

"I do not know either……"

There are many reasons for not moving.Either the pointer is not sensitive enough; or the friction between the coil and the base becomes larger; or there are too many clutter, and the pointer does not know which way to shake...

More sophisticated instruments are required.However, he won't do it.

In modern society, the social division of labor is becoming more and more detailed.Those who make instruments only make instruments, and those who see a doctor only care about seeing a doctor.Any doctor in the electrocardiogram room, pull them over and let them rub the instrument with their hands, dreaming!
Although the principle of this thing is actually simple.Gretel had heard gossip from his teacher in his previous life that the most primitive electrocardiograph was actually a string-type galvanometer—two strong magnets sandwiching a silver-plated quartz wire.However, the machining accuracy is too high.

The diameter of the quartz wire should be 0.0025mm, and then coated with a layer of silver, can you believe it? !
Accuracy, precision...without precision, everything is false...

Gretel stared at the ammeter that he had finally found out, his eyes were empty, and he almost sighed.By the way, even if he made a string-type galvanometer, it would be useless. The first thing he made weighed 300 kilograms and took up two rooms.

Instead of spending time on this kind of crap, it's better to go to the horn of Thunder with the paper and see which bigwig can help improve it.

Serila sat across from him, stretched out her hand and shook it, and then shook it again.Seeing that he didn't respond, he reached out and caught the wire of the ammeter...

"what?"

Her eyes lit up.Taking a peek at Gretel, he saw that he was still in the empty state, and he quickly untied the wires, two into one, and wrapped around his fingertips.

"Hey, it really has electricity!"

"Yes, there is indeed electricity." Gretel woke up with a start, raised his eyelids, and answered listlessly.

Yinlong, Yinlong, this talent is really amazing. With a wire in your hand, you can feel the current with your body...

However, how to turn the current she felt into an ECG waveform that anyone can see and record?

Gretel shook his head.

Celia shook her head.

The necromancer next to him: ...Although I can't understand what you are talking about, since I can't even understand, I'll just shake my head together...

Bernard driving outside: All three of them shook, do you need me to shake it together?
"If you can't figure it out, you can't figure it out." The silver dragon girl suddenly clapped her hands, her eyes sparkling:
"Don't worry, when we get to Auntie's place, Auntie will definitely have a solution! She has the most powerful magic!"

"This—" Gretel hesitated.Before, Cerilla dragged him away desperately because he couldn't explain the principle of the electrocardiogram. Cerilla wanted to ask her aunt to take a look.However, Gretel's idea was to get things out before then——

No knowledge costs nothing.Please ask a silver dragon, or an adult silver dragon, to help me study the electrocardiogram. I won't be able to pay back the reward if I sell it, right? !

"Oh, it doesn't matter!" The silver dragon girl waved her hands with confidence, and said:
"My aunt is pregnant, and she is not allowed to go out to play. She is so boring! Let's go to her at this time, no matter what, she will definitely welcome it!"

... How long will it take for the silver dragon to embrace the nest? ?If it is more than one year, and it is a healthy dragon, there is no nausea, vomiting, pregnancy-induced hypertension, and gestational diabetes, and it is really boring to be locked in a den...

There must be a road before the car reaches the mountain.It's a big deal, I turned around and hugged the thesis, and applied to the Magic Council for project funding.The research on the electrocardiogram was temporarily stuck in a bottleneck. Gretel held his chin and thought for a moment, put aside his thoughts, and hooked his fingers at the necromancer:

"Do me a favor and move the rabbit over here."

Leon pressed his backhand on the rear compartment panel, squirmed, squirmed, and moved over with the rabbit.Cerilla moved forward a few times, stared at the rabbit she had just rescued, and then looked at Gretel:

"...What are you going to do? You won't have to have another abdominal dissection?"

"No dissection this time." Gretel had a smile on his face, but his eyes were extremely serious.He pressed the rabbit's right hind leg with his left hand, turned out the blade with his right hand, and finished the skin lightly.With the index finger and middle finger of the right hand together, he groped back and forth on the rabbit's groin, feeling the throbbing of the femoral artery.

here it is!

With a lift of the hand, [Magic Trick] accurately dyes the femoral artery.Cleansing technique, iodine, alcohol, after three cleanings, [Delay Pain] falls.

"Cerilla, don't move!"

As he ordered, he wiped the space bag, and the sealed syringe fell into the palm of his hand with the glass case attached.Before everyone could react, Gretel unpacked, took out the syringe, aligned the needle tip at the marked position, and pierced downward at a 45-degree angle.

The silver dragon girl took a small breath.She glanced at Gretel quickly, and quickly covered her lips:

Don't bother me at this time!If the sound is louder and Gretel shakes his hand, that rabbit is about to bleed again!
Fortunately, the needle advanced only a little and then stopped.Gretel withdrew the syringe slightly. Seeing the blood flow out from the end of the needle, his hand trembled, and the magic power gushed out, and he immediately removed the syringe barrel.Celera breathed a sigh of relief, raised her fingertips, white light flickered slightly, and looked sideways at Gretel inquiringly:
are you done?

Want to help with treatment?

Gretel looked down at her.Putting down the syringe, he slapped the space bag again, and a handful of seeds fell into his hand.Soon, a green vine was swaying in the wind, holding a silver thread thinner than a hair, it silently slipped into the needle.

Gretel pursed his lips tightly, his eyes focused.The left hand took out the [Endless Ink Pen] and stuffed it under the rabbit, and the right hand urged the vines to keep moving forward.Go in, go in, the shadow on [Detect Magic] clearly shows that the vine has passed through the needle tube and entered the femoral artery!

Now there is no need to insert a catheter, so the puncture needle does not need to be withdrawn-just in time, there is no need to find ways to find the catheter sheath.Next, the vine took the silver thread and went up with all its strength!
Go against the direction of blood flow, enter the external iliac artery, enter the common iliac artery, enter the abdominal aorta, enter the thoracic aorta—make a bend along the aortic arch, and go straight to the heart!
"It's inserted into the heart!" Cerilla tightly covered her lips, and her fingertips pressed white on the top of her lips.She was short of breath and her eyes were wide open, as if the vine had penetrated not the rabbit's body, but her own heart:

"Gretel, what are you doing? Are you going to kill it?"

"Hush! It won't die!"

It's just a catheter inserted into the heart!The pioneer who created interventional surgery back then inserted a catheter into the heart through the median vein of the left elbow, and took an X-ray, and he lived well!

****
That Dr. Fussman is really amazing...do it yourself and insert it for yourself...
