Chapter 406 Insert the Vine Into the Heart!

Once, twice, three times. An extremely slight shaking that is almost imperceptible to the naked eye. If it weren't for the fact that the ammeter was placed on a floating dish and would not be shaken by the carriage at all, Grete could almost believe that the pointer was being shaken wildly.

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

Not moving anymore.

"Oh, why aren't you moving?"

"You're not dead? You're obviously still angry?"

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

"I don't 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 has increased; or there is too much clutter, and the pointer does not know which way to swing...

More sophisticated instruments are needed. But, 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 treat patients only treat patients. 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. Grete heard gossip from his teacher in his previous life. The most primitive electrocardiograph was actually a string galvanometer - two strong magnets sandwiched between a silver-plated quartz wire. However, the processing accuracy is too high.

The diameter of the quartz wire should be 0.0025mm, and then it should be coated with a layer of silver. Can you believe it? !

Accuracy, accuracy... Without accuracy, everything is fake...

Gretel stared at the ammeter that was easily rubbed out, his eyes blank, and he almost sighed. By the way, even if he made a string galvanometer, it would be useless. The first thing he made weighed 300 kilograms and took up two rooms.

Instead of spending time fighting this crappy thing, it would be better to go to Thunder Horn with your paper and see who can help improve it.

Serila sat opposite him, stretched out her hand and shook it again. Seeing no response from him, I reached out and touched the lead of the ammeter...

"Huh?"

Her eyes lit up. He peeked at Gretel and saw that he was still in an open state. He quickly untied the wires, merged the two wires into one, and wrapped them around his fingertips.

"Hey, there really is electricity!"

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

Silver Dragon, Silver Dragon, this talent is really amazing. Holding a wire in your hand, you can feel the electric current with your physical body...

But how to turn the current she feels into an electrocardiogram waveform that anyone can see and record with the naked eye?

Gretel shook his head.

Cerira shook her head.

Necromancer on the side: ...Although I don't understand what you are talking about, but since I can't even understand, I still shake my head together...

Bernard, who is driving the car outside: All three of them have shaken, do you need me to shake it together?

"If you can't think of it, you can't think of it." The silver dragon girl suddenly clapped her hands, her eyes shining brightly:

"Don't worry, when we get to my aunt, she will definitely find a way! She has the most powerful magic!"

"This-" Gretel hesitated. Cerira had dragged him away before because he couldn't explain the principle of an electrocardiogram. Cerira wanted to ask her aunt to help her take a look. However, Grete’s idea was to get things out before that——

No knowledge comes without a price. Please ask a silver dragon, or an adult silver dragon, to help me study the electrocardiogram. I won't be able to repay the reward even if you sell it, right? !

"Oh, it doesn't matter!" The silver dragon girl waved her hand confidently and said:

"My aunt is pregnant, and she is not allowed to go out to play. She is bored to death! If we go to her now, no matter what we do, she will definitely welcome us!"

...How long does it take for a silver dragon to nest? ? If it's been more than a year, and you are a healthy dragon with no nausea, vomiting, pregnancy-induced hypertension, or gestational diabetes, being locked up in a den will be really boring...

There must be a road before the car reaches the mountain. At worst, I would go back to the Magic Council and apply for project funding with my thesis in hand. The research on electrocardiograms temporarily hit a bottleneck. Grete held his chin and thought for a moment, then put aside his thoughts and raised his fingers to the Necromancer:

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

Leon put his backhand on the car board behind him, squirming, squirming, and moved over with the rabbit. Cerira moved forward, stared at the rabbit she had just rescued, and then looked at Gretel:

"...What are you going to do? You're not going to have a dissection again, are you?"

"I won't cut my belly open this time." Gretel had a smile on his face, but his eyes were extremely solemn. He held down the rabbit's right hind leg with his left hand, turned out the blade with his right hand, and finished the skinning with ease. The index and middle fingers of the right hand were put together and groped back and forth on the rabbit's groin, feeling the vigorous beating of the femoral artery.

It's here!

Raising his hand, [Magic Trick] accurately dyes the femoral artery with color. Cleansing technique, iodine, alcohol, after three cleanings, [delaying pain] fell.

"Serila, don't move!"

As he ordered, he touched the space bag, and the sealed syringe and the glass box fell into his palm. Before anyone could react, Grete unpacked the package, took out the syringe, aligned the needle tip with the mark, and inserted it 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 disturb me at this time! If the sound gets louder and Gretel shakes his hand, the rabbit will bleed again!

Fortunately, the needle only advanced a little and stopped. Gretel pulled back the syringe slightly, and when he saw the blood flowing out from the end of the needle, his hand shook, magic power surged out, and he immediately removed the syringe barrel. Cerela breathed a sigh of relief, raised her fingertips, the white light flickered gently, and turned her head to look at Grete inquiringly:

are you done?

Do you want help with treatment?

Gretel lowered his head and did not look at her. Putting down the syringe, he tapped the space bag again, and a handful of seeds fell into his hand. Soon, a green vine swayed in the wind, holding a silver thread thinner than a hair, and silently slipped into the needle tube.

Grete pursed her lips tightly and looked intently. He took out the [Endless Ink Pen] with his left hand and stuffed it under the rabbit, and used his right hand to push the vines forward. It's in, it's in, the shadow on [Detect Magic] clearly shows that the vine has passed through the needle and entered the femoral artery!

Now there is no need to insert the catheter, so the puncture needle does not need to be withdrawn - just right, there is no need to find ways to find the catheter sheath. Next, the vines move upward with all their strength, carrying silver threads!

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!

"Inserted into the heart!" Cerela covered her lips tightly, pressing her fingertips above her lips until they turned white. She was breathing rapidly and her eyes were wide open, as if the vine was not inserted into the rabbit's body, but her own heart:

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

"Shhh! It won't die!"

It's just a catheter inserted into the heart! The pioneer who pioneered interventional surgery inserted a urinary catheter into the heart through the median vein of the left elbow and took an X-ray. He was still alive and well!

That Dr. Forsman is so awesome... he did it himself and inserted it...
