Chapter 191 188. I'll show you something more fun

Just as Vienna was looking forward to this open-air operation, Kawei and his experimental team became very interested in a machine just produced from the Laslow Foundry. To be precise, it should be except Kawei.

For others outside, Kawei's interest is pretending.

After all, this thing has been with him since he studied medicine, and more than 40 years have passed.

"This thing is really interesting." [1]

Savalin pinched a rubber ball, felt the pressure generated by a circle of cuffs on his left upper arm, swept away the haze of the experiment a few days ago, and shouted excitedly: "Look, look, it's now up to 160!!!

”

"Can you hear the sound?" Koch sat next to him, looking curious.

"Well, I can hear some more." Savalin wore a stethoscope and pinched the ball a few more times, "It's here, it's 180, and the sound will disappear immediately!"

“It really disappeared???”

"It disappeared, all the pulsation sounds of blood vessels disappeared!" Savalin was very excited. "This cuff was like a big hand, pinching the blood vessels of my entire arm to close."

"Try it for me!"

"Don't be anxious. I have to slowly release it as written in the instructions." Savalin found the air-discharge valve on the ball, and his eyes found the scale of the mercury, and continued, "Relaxed it while still

I also have to look at the scale and listen to the sound in the stethoscope."

“How many do you want to put?”

"I don't know." Savalin looked at the description in the instruction manual again, "I just said that when my blood pressure reaches my level, I can hear the sound in my ears, and the mercury will shake up and down."

"It's amazing. It's much simpler than the metal blood pressure stent I used before." [2]

"Shh"

Savalin's attention is now all focused on his eyes and ears, fearing that he will miss this historic moment.

The liquid level above the mercury slowly falls as the gas in the cuff is lost, and the pressure on the outer ring of Savalin's left upper limb is also slowly weakening. No one knows when the brachial artery will resume its pulsation, and no one knows the stethoscope.

Can the sounds match?

All unknowns disappeared under the sound of a crisp arterial blood vessel impact.

"Here's here!!!" Savalin was particularly excited, "Merglass is also moving, it's really moving, this is the change of pressure in the blood vessels, dong, dong, dong."

This pulsation continued to a lower level and then disappeared into his ears. In addition to Kavi, Savalin became the first person to try to use this blood pressure monitor and successfully recorded it.

Your own blood pressure value.

"It's not bad, very interesting." After untiing his cuff, he was still a little unfulfilled. "When the pressure was raised to 180, it seemed like he was in the dark. It was not until the moment the blood vessels stretched out the bondage.

The feeling of breaking away from the quiet night.”

"Try it for me, too."

Savalin took off the stethoscope and pushed the entire machine in front of Koch: "Although the structure and principle are simple, it still requires a little trick to operate. Pay special attention to the speed of deflation, not too fast or too slow.

.”

"Yeah, understand!"

Koch also learned it and copied it according to his words. He quickly got a very good experience: "It's not bad, I feel that when the sound appears, I can sense the impact in my blood vessels."

"It seems that I will feel the first time." Savalin nodded, "Why do I try again."

"Hey? Shouldn't it be my turn now?" Matic stood aside and couldn't hold back, "It's agreed to be one person once."

"Okay OK, I'll try it after you've played it."

The blood pressure monitor turned around several times in the hands of the three of them, and only came to an end after Kawei came back from the dean's office: "The laboratory we applied for expansion has been approved, and the dean promised that half of the floor on the third floor will be under my jurisdiction.

.”

"So awesome!"

"That's great, so you can separate out new animal breeding rooms without having to squeeze together!"

"At that time, not only will there be voles, but also dogs, rabbits, and sheep."

The distribution of the laboratory was expected by Kawei.

In just over a month, Kawei produced several new drugs. Although it has not yet been unanimously recognized by the outside world and Kawei's paper has not been published, the effect of the drug is obvious.

At least it played a very good role in the patient, and no many flaws were found.

Two of these have applied for national patents, and methylene blue cavi has half of them. The effect of adrenal extract is even more amazing. It is only a matter of time before patents are patented. Such a high-yield experimental team is worth allocating to a more advanced laboratory.

The three of them surrounded the laboratory bench and were still discussing the next experimental project. Only then did Kawei notice that they had played the blood pressure monitor for an entire hour and a half: "Why are you still playing?"

"This thing is so fun."

"It's much simpler than the one used in the hospital." Koch put on the stethoscope and came again. "When we start production, we may not be able to afford it, so we naturally have to play more now."

"How could I not afford it? I only priced at 50 kronor." Kavey said, putting down the laboratory transfer procedures.

"Only 50?"

"This is the first blood pressure monitor in the world that anyone can use can learn. It is much simpler than the old antique I used before!"

Matic, who was born in a bourgeois family, really doesn't understand why Kavi did this: "According to market laws, this kind of epoch-making work must be sold for 300, no! 500 kroner per unit. This way, it can reflect its due value.

, it can also make people notice the efforts put in by researchers."

"But it costs only 20 kroner, and I'm already selling very expensively," said Kavey.

"You really lack business acumen!!!"

Kawei is definitely not as unbearable as he said, but I think the principle of a blood pressure monitor is not difficult to understand. Imitation products will appear sooner or later after the finished product enters the market. There is no need to set the price too high. In fact, with its mission, Kawei is not

The price may be too high.

"It's okay, it's just some money, so what if it's more."

Kavi smiled, nothing to defend: "By the way, what do you think this machine is used? Is there any improvement? If you have any opinions, I can discuss it with the design team in Laslow Foundry

Make improvements.”

"The measurement method seems simple, but it requires mobilizing the eyes, ears, hands and three parties to act together." Savalin hasn't shown such a gratifying smile for a long time. "It is indeed a good machine. If it finds its purpose, the sales should be very good.

”

The evaluation is reasonable.

Compared with the most commonly used folding blood pressure meter in modern times, the Kavi model cannot be folded and takes up a larger volume. It is easy to operate, in fact, compared with the past, compared with those fool-style electronic products in modern times, this model is clinical.

The blood pressure monitor that has been popular in the first line for more than a hundred years is still a bit complicated.

In fact, it is a problem of design principles, and it can solve all the problems it can solve. The problems it has become meaningless because of its cheap cost and accurate value. So after it was born, all people can do is structure.

The fine-tuning on the top is not necessary to change the kernel at all.

Even the electronic blood pressure meter that has begun to become popular cannot match the sense of calculating blood pressure by hand. The values ​​on the LCD screen are no more intuitive than the sound of blood vessels after they are rushing open.

After all, it adds sound on the basis of the scale value, and presents the pressure in the blood vessels to the examiner in a better way.

"There are many uses, at least when surgery deals with major bleeding in the wound, relying on the relationship between blood pressure and blood volume, the blood loss of the injured can be clarified."

Kavi did not rush to say too much, but changed the topic: "I can discuss the purpose in the future. What I care more about now is your blood pressure. Savalin, what is your blood pressure?"

Savalin handed over his own recording paper, and he wrote down the values ​​and time of each test. The habits accumulated by a large number of experiments are very good, but the values ​​on the paper are not very good, and the quality of these values ​​is also good.

It was soon reflected on Kavi's face.

Systolic blood pressure 154, diastolic blood pressure 92, typical hypertension, if combined with Savalin's age, the prognosis is not optimistic. Of course, hypertension is a chronic disease. If it is considered only, it should be much larger than the average life expectancy. In this era

There doesn't seem to be too pessimistic.

But he is at least half of his "employee". As the "boss", Kawei still needs to take good care of him.

"What's wrong with you?" Savalin thought that his record format or content was not in compliance, so he went up and asked, "Did I record it wrong?"

"It's okay, it's okay."

Kawei didn't know how to tell him, so he could only turn his head and look at Matic and Koch's blood pressure. Both of them had normal blood pressure. He finally breathed a sigh of relief. Kawei put down the recording paper and looked at Savalin. Suddenly

He asked, "By the way, how long have you been working here?"

"It's been two months since the hospital period."

Apart from the awkwardness of animal safety along the way, Savalin was very reassuring in other situations, and he worked very hard: "Why did you suddenly ask this? You might as well want to fire me, right?"

"No," Kawei started chatting with him with a smile, "You spend your time in the laboratory every day, and you often work until late. Now the laboratory has improved, and a new place has been replaced, and the experimental project has been basically completed.

I think I should give you a holiday.”

Savalin is indeed time to rest. This kind of hypertension is likely triggered by staying up late for a long time.

But he himself did not want to rest, because once he rested, he would be lost, and if he lost his job, he would be unearned. Savalin was no more connected and scholarship than Koch, nor was he richer than Matic's wealth. The laboratory was his only

There is a way to make money, so it cannot be broken.

"No, why am I so young for vacation?" he joked. "I'm thinking of buying an apartment on the Ring Road, and then I can go to the theater to listen to opera or something."

"I'll give you paid leave."
