Chapter 494 A New Tool for Torture, the Invasive Blood Pressure Monitor!

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

Wizard Norwood and Aurora answered in unison. The two looked at each other, and Master Norwood raised his hand to signal Aurora to speak first:

Tsk, no matter what, Aurora is also the boss's first mage follower and a fellow disciple of the boss. Let him answer this kind of question - if resources are needed, it is their own family, which is more convenient to collect wool.

Seeing Master Norwood retreating humbly, Aurora continued without thinking. He raised his hand enthusiastically, and [Silent Phantom] spread out in the air, outlining straight lines and arcs:

"You know that our plastic energy department has a branch that studies force fields... Since we want to study force fields, we must measure 'force'. Then, this is the configuration -"

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

On the force field wall, readings popped up one after another.

"This thing is also used when making golems or similar magical creations in the transformation system. Engraving it on a special magic plane will show the magnitude of the force." Mr. Norwood continued steadily:

"The alchemy workshop has finished parts for sale, and I happen to have a few here. If sir, I will bring them after dinner."

It is best to have finished parts. After dinner, a group of people gathered around Grete's laboratory, watching him remove the plunger of the syringe, fill it with physiological saline, and install the finished parts for measuring the force field on the top of the syringe. Raise the dog's legs and insert a needle——

"It's moving! It's moving!"

The magicians cheered:

"Really blood pressure! - Hey, it's changing!"

Grete carefully adjusted the height of the dog's legs to ensure that the finished parts were at the same level as the dog's heart on the experimental bench. The magic array emits a curtain of light, with lines and numbers going up and down, changing constantly——

Although the standards are different and cannot directly display the number of millimeters of mercury, the changes in diastolic and systolic blood pressure can be clearly seen.

"Look, the one with the highest number is the systolic blood pressure, and the one with the lowest number is the diastolic blood pressure." Gretel pointed to the light screen and explained to Cerela:

"As long as the normal value of blood pressure is measured, when a person is particularly irritable or dizzy, or when the weather is suddenly cold, or when a berserker becomes a mad warrior, you can measure the blood pressure and you will know how much it exceeds the standard. Or, measure My blood pressure was too low when I came out. It was probably due to excessive blood loss..."

"Interesting! Let me try it!"

Cerira pulled out the syringe, dropped a healing spell, and found another sheep. Gretel quickly 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 insertion of the needle is wrong. You may have punctured the blood vessel..."

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

Gretel guided me very patiently. Seeing that Serila had finally succeeded in getting the needle, and observing the waveform with a happy face, he found every opportunity and explained to Anivia, who was following closely with a worried look on her face:

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

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

"Let me check my blood pressure..."

Cerela looked innocent. Before he finished speaking, 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 in silver on the top of the syringe...

All turned into ashes and disappeared.

Girl, don’t you know how corrosive the dragon blood is?

"Well……"

Cerira stuck out her tongue sheepishly. Gretel ignored his invasive blood pressure monitor and rushed forward to hold Cerrela's arm. One hand was pressing hard to stop the bleeding, and the other hand was condensing healing skills, desperately pressing on the bleeding area...

Drawing a line elsewhere is nothing, but here it is an artery! artery!

Even if there is a puncture, bandaging alone cannot stop it. Pressure must be applied to stop the bleeding!

Well, although after the silver dragon turned into an elf, Gretel didn't know whether his blood pressure would maintain the strength of a dragon or what the direction of his blood vessels would be...

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

Gretel: "..."

Okay, Dragon Clan, resilient and willful.

"I'm sorry, I broke your things..." Cerela squatted on the ground and picked at the ashes. She was sure that there was nothing worth saving. She looked up with guilt on her face. Looking left and right, his wrist flicked, and several gems jingled down:

"Well, I'll apologize... let's do another one..."

"...Forget it, this thing needs to be changed anyway." Gretel rubbed his brows, took Serira back to the laboratory, and captured Aurora again:

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

Now this number looks really annoying...if it is not changed into millimeters of mercury, or how many hectopascals, it is completely useless!

The first request was not difficult, it just took some time to measure and adjust the magic circle. Aurora took care of it and said he could handle it. As for carving parts, as long as you contribute a little, someone will be able to do it.

The latter one is not so easy:

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

"MOSS is okay." Ta Ling's stern electronic voice interrupted in time.

But Taling couldn't carry it around on his back. Grete sighed, and Mr. Norwood asked in due course:

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

Remember that you placed the order for rubber just to make this thing. Now that there is a new plan, can we still make rubber?

After all, there are thousands of recipes, and it’s still scary to try them one by one...

"Do it." Gretel sighed:

"Mr. Norwood, the sphygmomanometer I am making now is an invasive sphygmomanometer, which is inserted into a person's artery; the one made of rubber tube is a non-invasive sphygmomanometer, which can be measured without opening an opening in the human body. If you are Would the patient rather have a cut in his body or be surrounded by a rubber airbag?"

Then decisively choose the air bag! Master Norwood suddenly understood, rolled up his sleeves and went to work. Grete promised him that the rubber products and patents he made would be his in name, and he would publish the paper and give him half of the income.

That’s 50%!

The boss lives in the mage tower, spends the boss's budget, and does the tasks given by the boss. Once you make something, you can still get half of the income!

Where can I find such a good boss?

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

Adjustments came and went, Grete tested it with a water column, and the reading was finally accurate. The next step was——

"Now that the animal experiments are done, who should we turn to for the human experiments?"

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

Hospital?

After being beaten, smashed, and robbed in the past, the hospital's business has been sluggish recently and it has returned to a deserted state.

Workhouse?

In order to test the new equipment, they went to the workhouse to capture the poor people and poke a hole in each of their arteries. Gretel felt that since he couldn't do such a thing, he should wait until Mr. Norwood's rubber was ready.

While he was struggling, Archmage Grom came to see him and was overjoyed to see this new blood pressure monitor. Without any hesitation, I brought a batch of blood pressure monitors and parts, as well as magic array blueprints...

Three days later, he was very happy and came over to brag to Gretel:

"Gretel! This thing you made is so useful! Do you still remember the assassin you caught last time? Everyone is doubtful whether what he confessed before is true. As soon as your thing is plugged in, Guess what, he was shaken!”

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

Even so, he became curious and followed Archmage Grom there to see what was new. High-level infiltrators caught by the council are always sent directly to the Tower of Babel, where they are suppressed by the magic circle and guarded by the tower spirit. The control department and the illusion department jointly tortured each other, and the prophecy department was responsible for verifying the answers...

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

He spread his right hand forward, and inserted a needle into his forearm near his wrist. Blood poured into the needle, and the numbers on the light screen went up and down, changing constantly.

Opposite him, an unknown magician sat upright, pointing at the light screen, and threatening the other person:

"Look, your blood pressure has risen...you're nervous! Being nervous means that what you just confessed must not be true!"

Gretel:! ! !

Wait, your lie detector is too cruel! And if it is kept plugged in, without heparin saline flushing, the blood will coagulate quickly! What anticoagulation did you use? The anti-coagulation magic of the necromancy system?

In addition, relying solely on blood pressure data is inaccurate!

He quietly retreated to the door. After the magician in charge of the torture exited, he cautiously made a suggestion:

"Well, actually, electrocardiogram, blood pressure monitor, and brain waves are used together to detect lies more efficiently... But I don't have the data, so I have to accumulate it from scratch..."
