Chapter 712 Rabbit and Camelia
However, none of the doctors mentioned that syringes would reduce the pain of patients.
Joseph interrupted everyone's admiration and asked: "So, who can make this thing?"
Lamax thought: "Clockmakers. They can make very special things. Fine parts.”
“Jeweler.” Perna said, “The most complicated part of this syringe is the hollow needle. I have seen the barrel of Her Majesty’s hair ornament. ”
Joseph immediately remembered his mother's warship hair accessory, the barrel of which was only slightly thicker than a toothpick.
He nodded and said: "Call the watchmaker and the jeweler. Oh, and borrow two more 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 their tools and began trial production.
The jeweler rolls a piece of silver into a hollow tube as thick as a toothpick, burns it until it turns red, and then slowly stretches it between the two ends.
As the silver tube grows longer, its diameter also becomes smaller.
But when it reached half the thickness of a toothpick, it suddenly broke in the middle.
The jeweler was not discouraged and quickly threw away the scrap and started the next attempt...
The syringe was originally given to the locksmith to be made of brass, but it was soon discovered that melting-casting It was such a waste of time that I finally decided to use fusible tin instead.
Although Joseph knew that tin usually contained a small amount of lead, if only a few injections were performed, the harm would be minimal, so he did not interfere.
After all, speed is the most important thing right now.
Two hours later, a dark silver syringe slightly thicker than a locksmith's thumb and somewhat crude in shape was placed in front of Joseph.
In order to facilitate processing, the needle is directly welded to the tin barrel.
The pusher rod and the piston are a whole oak stick - this is the easiest solution to meet the sealing requirements.
In short, everything seems a bit crude.
But the silver needle was anything but adequate. After the jeweler tried dozens of times, he finally stretched its diameter to a level close to that of later generations of intramuscular injection needles.
Joseph tested it with water and confirmed that the syringe was usable, and immediately gave it to Perna for fumigation and disinfection.
More than ten minutes later, at the suggestion of the Crown Prince, Dr. Lamarck reduced the dosage 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 had brought the liquid used to dilute penicillin, and asked cautiously: "Doctor Lamarck, is this?"
"Don't worry, it's distilled water. ”
For doctors in the 18th century, this was definitely a huge improvement. Normally, doctors would dilute medicines directly with water, or even use water from the Seine...
After all, Lamarck had heard the crown prince talk about medical disinfection.
However, Joseph still felt that something was wrong, but he couldn't remember it for a while. He could only watch Lamarck dilute the medicine and inhale it into the syringe very unfamiliarly.
Then, the needle, which seemed to Joseph to be terrifyingly thick, was inserted into the vein on the inside of Camelia's elbow by Lamarck with great precision.
After all, he is the top surgeon in Europe, with accurate and steady hands.
Watching the potion being slowly injected into the body of the maid, Joseph suddenly slapped his forehead, remembering what he had forgotten just now, and said anxiously:
"Stop! Stop! No skin test..."
< br>Lamarck was startled and hurriedly pulled out the needle.
Joseph looked at the position of the putter and found that he probably hit less than a quarter of it, 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 I have injected rabbits many times, and there has never been any allergic reaction."
"That's right. They are lucky..."
After observing for more than ten minutes, it was confirmed that Camelia had no signs of allergies. Joseph was relieved. He was about to let Lamarque continue the injection, but saw Camelia frowning. Wrinkled, kept shouting "hurt".
Perna hurriedly went to comfort her: "His Royal Highness has given you 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 her arm, it hurts a lot."
Perna helped her rub the area near the needle and said softly: "It was 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 were not like allergies.
He suddenly slapped his forehead again and looked at Lamarck: "It seems that physiological saline should be used to dilute the medicine."
"Saline solution?"
"It's 0.9% saline."
"Why?"
"It seems to be some osmotic pressure..."
Joseph only remembered that in his previous life, intravenous injections 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, when I experimented with rabbits 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 seriously against this Referring to her as a "big human rabbit".
Joseph sighed: "Is the rabbit struggling hard?"
"It seems, yes."
"It hurts." Joseph gestured to the hospital bed , "That's what Camelia is like."
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 to add more salt Layer filtration.”
“Okay, Your Highness. I’ll get ready.”
Fortunately, the equipment in the pharmaceutical factory’s laboratory is very complete, and an assistant will be there in more than ten minutes. A glass of filtered salt water was brought over.
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 Lamarck: "Doctor Lamarck, please prepare some more glucose and give her an injection."
" Glucose?”
Joseph frowned, maybe glucose hasn’t been discovered yet?
He tried to describe: "It's the kind of special sugar extracted from grapes, it has no sweetness..."
Lamarck suddenly realized: "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 needs to be purified many times with 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 and then waved excitedly Thermometer: “Thank God, 38.3 degrees! ”
