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

Chapter 494 A new tool for torture, an invasive blood pressure meter!

"A magic circle to measure pressure? Of course there is."

Magister Norwood and Aurora answered in unison.The two looked at each other, and Master Norwood raised his hand, motioning for Aurora to say first:

Tsk, no matter what, Aurora is also the boss's first mage follower and the boss's fellow disciple.Let him answer this kind of question - in case they need resources, they are also their own family members, so it is more convenient to collect wool.

Seeing that Master Norwood retreated modestly, Aurora didn't even think about it, and continued to talk.He raised his hand excitedly, and [Silent Phantom] unfolded in the air, outlining straight lines and arcs:
"You know that our evocation department has a branch that studies force fields... Since we want to study force fields, we must measure 'force'. Then, this is the configuration—"

A single configuration, lines, planes, and three-dimensional structure, is so complicated that it makes people dizzy.Aurora pulled out a force field wall and stood by the wall at the end of the restaurant. Magic missiles, wind blades, and flame rays hit it in turn.

On the wall of the force field, one after another, jump out of the reading.

"The transformation system will also use this thing when making puppets, or making similar magical creations. Engraving it on a special magic plane can show the magnitude of the force." Mr. Norwood continued steadily:
"The alchemy workshop sells finished parts, and I happen to have a few here. If you need it, sir, I'll bring it after dinner."

It is best to have finished parts.After dinner, a group of people gathered in Gretel's laboratory, watching him remove the plunger of the syringe, fill it with saline, and install the finished parts for measuring the force field on the top of the syringe.Elevate the dogleg, insert one needle——

"Move! Move!"

The magicians cheered:

"Blood pressure is real! - Hey, it's changing!"

Gretel carefully adjusted the height of the dog's legs to ensure that the height of the finished part and the dog's heart on the test bench were at the same level.The magic circle shoots out a light curtain, the lines and numbers go up and down, changing constantly——

Although the standards are not the same and the mmHg cannot be directly displayed, the changes in diastolic and systolic blood pressure can already be seen clearly.

"Look, the highest number is the systolic blood pressure, and the lowest number is the diastolic blood pressure." Gretel pointed to the light curtain and explained to Celera:

"As long as the normal value of blood pressure is measured, then when people are particularly irritable, dizzy, or when the weather is suddenly cold, or when a berserker goes berserk, measure the blood pressure, and you can know how much it exceeds the standard. Or, measure The blood pressure is too low when it comes out, it is likely that there is too much blood loss..."

"Interesting! Let me try!"

Cerilla pulled out the syringe, dropped a healing spell, and found another sheep.Gretel hurriedly stopped her:
"Wait! You can't mix needles! Get another one!"

"Hey, why not?"

"...you inserted it in the wrong place...this is a vein, not an artery..."

"The angle of the needle is wrong, you are piercing the blood vessel..."

"The angle is too high! It's too high! Lower it!"

Gretel guided with considerable patience.Seeing that Cerilla finally got the needle successfully, and observed the waveform with a happy face, he saw the stitches, and explained to Aniviya who followed her step by step, with a worried face:

"Invasive blood pressure monitoring is a very useful monitoring method in clinical practice. Since you have chosen the path of being a healer, you'd better learn it too. I'll write down the operation essentials later—Cerilla, what are you doing!!!"

Miss Yinlong pulled out the syringe, replaced a needle, and pierced her left wrist with her backhand!

"I measure my blood pressure..."

Celia looked innocent.Before the words fell, the bright red blood rushed out of the needle and shot to the top of the syringe...

There were a few soft sounds, the needle made of stainless steel, the glass syringe, and the magic circle etched with silver on the top of the syringe...

All turned into ashes and disappeared.

Girl, don't you know how corrosive the dragon's blood is?
"Uh……"

Celia stuck out her tongue embarrassingly.Gretel didn't care about his invasive sphygmomanometer, and rushed forward to hold Cerilla's arm.With one hand pressing hard to stop the bleeding, the other hand condensed healing skills, pressing desperately to the bleeding place...

Drawing a line in other places is nothing, but here is an artery!artery!
Even if a wound is poked, it cannot be stopped by bandaging alone, and pressure must be applied to stop the bleeding!

Uh, although after the silver dragon becomes an elf, whether the blood pressure will maintain the intensity of the dragon, and what the direction of the blood vessels is, Gretel is not very clear...

The white light was broken away as soon as it fell.Cerilla pressed the center of her left forearm with her right thumb, raised her arm, and licked it back and forth twice.When I put down my hands again, my wrists and arms were smooth and crystal clear, with no trace of blood, scars or subcutaneous bleeding.

Gretel: "..."

Come on, dragon family, strong resilience, willful.

"Sorry, I broke your things..." Cerilla squatted on the ground and picked up the ashes, making sure that there was nothing worth saving. She looked up with guilt on her face.Look left, look right, with a flick of the wrist, a few gems clang down:

"Well, I'll pay... Let's make another one..."

"...Forget it, this thing has to be changed anyway." Gretel rubbed his brows, brought Cerilla back to the laboratory, and caught Aurora again:

"Is there any way to change the value? Change the reading to millimeters of mercury, er, equal to the pressure of how many millimeters of mercury? Add a few more functions, for example, to record waveforms and numbers, such as real-time on paper tape Draw it?"

Now this number looks really annoying... If you don't change it to mmHg, or change it to how many hPa, there is no way to use it at all!
The previous requirement was not difficult, it just took some work to measure and adjust the magic circle, and Aurora took care of it all, saying that he could handle it.As for the engraving of parts, as long as the contribution points are thrown out, someone will naturally be able to do it.

The latter is not so easy:

"This kind of real-time recording, I remember that high-level tower spirits can do it... such as Mr. Gregory, or the tower spirit of Tongtian Tower. Otherwise, you can ask MOSS?"

"MOSS is fine." Taling interjected in time with his steady electronic voice.

But Taling can't carry it around.Gretel sighed, and Mr. Norwood asked at the right time:

"Then... can you still make rubber?"

Remember that you placed an order for rubber just to make this stuff.Now there is a new plan, can rubber still be made?
After all, there are thousands of recipes, trying them one by one, it is still very scary...

"Do it." Gretel sighed:

"Mr. Norwood, what I'm making now is an invasive blood pressure monitor, which is inserted into a person's artery; a non-invasive blood pressure monitor made of a rubber tube, which can measure without opening an opening in the human body. If you are Patient, would you like to have an opening in your body, or would you like to be surrounded by a rubber airbag?"

Then choose the airbag decisively!Master Norwood suddenly realized, rolled up his sleeves and went to work.Gretel promised him that the finished rubber products and patents he made would be owned by him in name, that he would publish the papers, and give him half of the income.

That's 50%!
The boss's mage's tower lives, spending the boss's budget, and doing the projects given by the boss.After making something, the income can be divided in half!
Where can I find such a good boss?

The development of Gretel's invasive blood pressure monitor went quite smoothly.It took Aurora three days to re-measure the pressure of the mercury column, compare it with the reading on the magic circle, and modify the subtle structure inside the magic circle.

Adjusting, adjusting, Gretel tested with the water column, and the reading was finally accurate, and the next step is——

"After the animal experiments are done, who should I ask for the human experiments?"

Gretel frowned.He's already tried it on himself: 110/78, pretty healthy.But blood pressure needs to be measured on a large scale to get the normal value range. One or two samples, or even one or twenty, one or two hundred samples, are of no use at all...

Hospital?

After being beaten, smashed and robbed before, the hospital's business has been sluggish recently, and it has returned to the state of being empty.

Workhouse?
In order to test the new device, go to the workhouse to catch those poor people, and poke each person's artery.Gretel felt that he couldn't do this kind of thing, so let's wait until Mr. Norwood's rubber is ready.

While struggling, Archmage Grom came to see him and was overjoyed when he saw this new type of blood pressure monitor.Without any explanation, even the parts of the blood pressure monitor, and the blueprint of the magic circle, they directly collected a batch of them...

Three days later, beaming, came and boasted to Gretel:

"Grete! This thing you made is so useful! Do you still remember the assassin you caught last time? Everyone expressed doubts about whether his confession was true. Once you plugged in that thing, Guess what, he was shaken!"

Gretel:? ? ?Wait, what I made is not a torture tool!

Even so, he became curious and followed Archmage Grom to see what was new.The high-level infiltrators captured by the council have always been sent directly to the Tongtian Tower, suppressed by the magic circle, and guarded by the tower spirit.The Confusion Control Department and the Illusion Department work together to torture, and the Prophecy Department is responsible for verifying the answers...

So the whole scene is clean and not bloody.What Gretel saw was a thin man who was sitting on an iron chair and his whole body was trapped in the iron frame.The head, torso, arms, and legs are all covered by metal shells, only half of the right arm is exposed.

The right hand spread out forward, and a needle was inserted into the forearm near the wrist, blood poured into the needle tube, and the numbers on the light curtain went up and down, changing constantly.

Opposite him, an unknown magician was sitting upright, pointing at the light curtain, threatening him:
"Look, your blood pressure has risen...you are nervous! If you are nervous, it means that what you confessed just now must not be true!"

Gretel: ! ! !

Wait, your lie detector is too cruel!And it has been plugged in and plugged in, without heparin saline flushing, the blood will coagulate soon!What anticoagulation did you use?The anticoagulation magic of the Necromancer?
In addition, blood pressure alone is inaccurate!

He quietly backed out the door.When the magician in charge of the torture quit, he cautiously made a suggestion:
"Well, in fact, electrocardiograms, blood pressure monitors, and brain waves are used together to detect lie more efficiently... But I don't have the data, and I have to accumulate it from scratch..."
