Chapter 711 Rabbit and Camelia

Chapter 712 Rabbit and Camelia

None of the doctors mentioned that the syringe would reduce the patient's pain.

Joseph interrupted everyone's admiration and asked, "So, who can make this thing?"

Lamarx thought, "A watchmaker. They can process very fine parts."

"Jeweler." Perna said, "The most complicated part of this syringe is the hollow needle. I have seen the Queen's hair ornaments, and the barrel on it is hollow."

Joseph immediately remembered his mother's warship hair ornament, and the barrel on it was only slightly thicker than a toothpick.

He nodded and said, "Call the watchmaker and jeweler. Oh, and borrow two locksmiths from my father."

Thanks to the developed rail transit system in Paris today, only one hour later, seven royal craftsmen arrived at the Paris Pharmaceutical Factory.

These top French craftsmen gathered around the standard drawings redrawn by the Crown Prince, discussed for more than ten minutes, determined the division of tasks, and then laid out the tools and began trial production.

The jeweler rolled the silver sheet into a hollow tube as thick as a toothpick, burned it to red, and then slowly stretched it by clamping the two ends.

As the silver tube continued to grow longer, the diameter became thinner.

But when it was only half the thickness of a toothpick, it suddenly broke in the middle.

The jeweler was not discouraged, and quickly threw away the waste and started the next attempt...

The syringe was originally given to the locksmith to make with brass, but it was soon discovered that melting-casting was too time-consuming, and finally decided to use fusible tin instead.

Although Joseph knew that tin usually contains a small amount of lead, if only a few injections were made, the harm should be minimal, so he did not interfere.

After all, speed is the most important thing at the moment.

Two hours later, a dark silver syringe that was slightly thicker than the locksmith's thumb and had a somewhat crude shape was placed in front of Joseph.

For ease of processing, the needle was directly welded to the tin syringe.

The push rod and the piston are a whole oak stick - this is the easiest solution to meet the sealing requirements.

In short, everything seemed a bit makeshift.

But the silver needle was not a makeshift one. After the jeweler tried dozens of times, he finally stretched its diameter to a level close to that of the later intramuscular injection needle.

Joseph tested it with clean water and confirmed that the syringe was usable. He immediately gave it to Perna for fumigation and disinfection.

More than ten minutes later, Dr. Lamarck, at the suggestion of the crown prince, reduced the amount of penicillin to 0.8 grams. He excitedly and unfamiliarly picked up the world's first syringe and prepared to inject Camelia.

Joseph noticed that Lamarck's assistant brought the liquid used to dilute penicillin, and hurriedly asked cautiously: "Dr. Lamarck, what is this?"

"Please rest assured, it's distilled water."

For doctors in the 18th century, this was definitely a huge improvement. Usually, doctors would directly dilute the medicine with clean water, or even with water from the Seine...

Lamarck had heard the crown prince talk about medical disinfection knowledge after all.

However, Joseph still felt something was wrong, but he couldn't remember it for a moment, so he had to watch Lamarck dilute the medicine and suck it into the syringe very unfamiliarly.

Then, the needle that seemed frighteningly thick to Joseph was inserted into the vein on the inside of Camelia's elbow by Lamarck with great precision.

After all, he was the top surgeon in Europe, and his hands were accurate and steady.

Watching the medicine being slowly injected into the maid's body, Joseph suddenly slapped his forehead, remembered what he had forgotten just now, and said anxiously:

"Stop! Stop! No skin test..."

Lamarck was startled and hurriedly pulled out the needle.

Joseph looked at the position of the putter, and it was probably less than a quarter, which was okay.

Lamarck said nervously: "You just said, skin test?"

"Yes, penicillin may cause allergies, and a small dose skin test should be performed first."

"But the rabbits have been injected many times, and there has never been an allergic reaction."

"That's because they are lucky..."

After observing for more than ten minutes, Joseph was relieved to confirm that Camelia had no signs of allergy. He was about to let Lamarck continue the injection, but he saw Camelia frowning and kept shouting "pain".

Perna hurried to comfort her: "Your Highness has given you a special medicine, and you will get better soon. Do you feel a headache or chest pain?"

"No..." The maid shook her head weakly, "It's my arm, it hurts."

Perna rubbed the area near the needle hole for her and whispered: "It's just a prick, it's okay."

"No, the whole arm hurts..."

Joseph frowned. He remembered that allergies would cause rashes, edema, and difficulty breathing. Camelia's symptoms did not seem to be allergic symptoms.

He suddenly slapped his forehead again and looked at Lamarck: "It seems that the medicine should be diluted with saline."

"Saline?"

"It's 0.9% saline."

"Why?"

"It seems to be some osmotic pressure..."

Joseph only remembered that the intravenous injections in his previous life were diluted with saline or glucose. He once asked the doctor why he did this, and the answer he got was to increase the electrolyte concentration, otherwise it would be very painful.

Lamarck blinked in confusion: "Your Highness, but when I used rabbits for experiments before, I used distilled water, and the effect was very good."

If the maid still had the strength at this time, she would definitely protest against the idea of ​​treating her as a "human-shaped rabbit".

Joseph sighed: "Is the rabbit struggling hard?"

"It seems, yes."

"It hurts." Joseph gestured to the hospital bed, "Camelia is like this."

Lamarck's eyes widened, obviously not understanding, but out of trust in His Royal Highness the Crown Prince's medical skills, he immediately nodded and said: "You mean, 0.9% saline should be used?"

"Yes, remember the salt needs to be filtered through multiple layers."

"Okay, Your Highness. I'll go get ready."

Fortunately, the equipment in the laboratory of the pharmaceutical factory was very complete. After more than ten minutes, an assistant brought over half a cup of filtered salt water.

Lamarck calculated the amount of salt that needed to be added based on the volume of distilled water in the syringe, weighed it and sucked it into the syringe.

The silver needle pierced Camelia's arm again, injecting all the penicillin into her blood vessels.

Joseph recalled that she had not eaten seriously for several days, and said to Lamarque: "Doctor Lamarque, please prepare some more glucose and give her an injection."

"glucose?"

Joseph frowned. Could it be that glucose has not been discovered yet?

He tried to describe: "It's the kind of special sugar extracted from grapes, without sweetness..."

Lamarck suddenly understood: "You mean the kind of sugar discovered by Mr. Graf? I have read his paper.

"I have to look through the information, and it seems that it requires multiple purifications using raisins."

Joseph breathed a sigh of relief: "Then I'll trouble you."

At 4 o'clock in the afternoon, Camelia woke up from a deep sleep, and her complexion was obviously not as bad as before.

Perna took her temperature, then waved the thermometer excitedly: "Thank God, it's 38.3 degrees!"
