When Yang Heng configured what culture medium and what agar, Sun Daochang and several other Dao Masters got busy, and even put Yang Heng aside, to be honest, when Yang Heng moved his professional knowledge, he suddenly found that he didn't know anything, and he couldn't even help at all.

At this time, even if it was Du Niang's upper body, Yang Heng couldn't help, so he just stared at the side, and he didn't even know if what they were doing was right.

What should I do, Yang Heng always felt that there was something in his mind that he had not thought of.

By the way, how is this penicillin used, it won't be applied to the wound like those penicillium, and if it is some diseases, there is no wound, this, how did the doctors in the previous life use it, it seems to be a powdery object, packed in a sealed glass bottle, dissolved with distilled water when used, and then injected into the skin or blood vessels.

By the way, this syringe is not yet there, so Yang Heng has a goal again, now for him, this penicillin is the most important thing, not to mention other places, that is, the workers of his family, once there is a bruise, a treatment is not timely, or even the treatment is not in place, it will cause infection, and many people have lost their ability to work.

There are also soldiers, they are on the battlefield, or on the training ground, once injured, there will be bacterial infection, that is also a fatal thing, although the injury is not very serious, but most of them have become disabled, this is still the result of alcohol disinfection, if there is this penicillin, how much will it reduce such disabilities.

Syringe. Naturally, it is the oldest glass syringe ever made. This doesn't have much technical content. As long as the glassworkers are careful, a lot can be made. Scales, don't use them temporarily, this, you need to let Sun Daochang study it himself, how many scales should be used.

Needles, stainless steel is impossible, but there is silver. Even gold.

This one was made by the jewellers, and they also worked out how to add something to make the gold and silver harder.

What else, distilled water, saline, glucose water, when Yang Heng personally made these things, he felt that this simple medical device. And some preparations are still very simple, but for high-temperature disinfection. He specially arranged personnel to make a high-pressure boiler, so that these medical devices can be well sterilized at high temperatures.

"Xiaoyou, look, isn't it like this, ah, what, how can it be like this?" That is, when Sun Daochang happily came out with some white powder wrapped in paper, he suddenly found that these things began to melt.

"That, Daochang Sun, I don't know if this is what I want, but looking at it like this, it should be like, this thing needs to be sealed and stored in a glass bottle, otherwise it will melt quickly due to moisture."

"Oh, I mean, is there a glass bottle?" "This needs to be made freshly, but we can first use a small test tube to fill it, and then plug the test tube mouth with a cork to see if it can be stored, Sun Daochang, how did you test this?"

"It works, every time we use some small animal cuts to test it, none of them will cause inflammation, and this state should meet your requirements."

"So, okay, Daoist Sun, shouldn't we find a real person to test it?" "Real person, try it, let the old man come first," he said with a knife and wanted to cut his arm.

"Hey, I said, Daochang Sun, don't be so anxious, this real person test, you don't need to do this, since you don't have anything to do with the animal test, then leave it to me next."

Saying this, Yang Heng took out a syringe, put the needle on, then used an alcohol cotton ball to eliminate the poison, took out a bottle of distilled water, pumped a tube of water, pierced it into the cork, and slowly injected the water into the powder......

"Little friend, what are you?" "Daochang Sun, you will know the Tao later, come, come here." Yang Heng pointed to a guard and said, since Sun Simiao has already tested it with animals, it proves that these things are not poisonous, but he is not allergic, he can't guarantee it, but he knows the allergy test, even if it is allergic, it is just a small place.

"Xiaoyou, why don't you let Lao Dao come, Lao Dao wants to feel the effect of this medicine." "Okay then, Daoist Sun, you're optimistic." ……

Under Yang Heng's explanation, he injected a little potion into Sun Daochang's arm, and even drew a circle with paint.

"Daochang Sun, if there is no reaction within half an hour, it proves that it has been successful, and we can marry someone who is suffering from inflammation to conduct a test." At this time, the microscope made by Yang Heng could not observe anything like bacteria, so Yang Heng still called some bacterial infections inflammation, at least, in this era, there is no responsibility to find fault with him.

During the waiting time, Yang Heng explained to Sun Simiao the use of this needle, and even the precautions, "Oh, Sun Daochang, I forgot, there is still something that can be made, we can slowly infuse into the blood vessels." When Yang Heng was explaining the injection, he remembered the matter of hanging a drip again, this is also very easy to do, but it is just a matter of a few tubes.

"Xiaoyou, don't worry, let's study this thoroughly first." "Well, okay, I'm in a hurry, mainly because I'm worried about some of our workers, you see that once they are injured and infected, they basically lose their ability to work, I'm anxious, when there was no penicillin before, I wasn't in a hurry, I was in a hurry, and there was no way, but with this thing, can I not be in a hurry?"

"Ha Luha, Xiaoyou, I understand your feelings, now that the time is up, shouldn't we have the next step of the test?" "You two, go and bring over a man who has been injured and not healed." "Little friend, let's go by ourselves, don't let them toss the injured person."

"Then, okay, Daochang Sun, didn't I see that your eyes were bloodshot, you haven't slept peacefully for a long time, right?" "It's okay, it's okay, it's not a problem." "Sun Daochang, this can't be done, if your body collapses, it can't be done, you have to know Lu Dao, this medical research still depends on you." Yang Heng was taken aback, if Sun Simiao's lifespan was reduced because of his arrival, it would be really a sin, a sin.

"Don't worry, Xiaoyou, Lao Dao's body is Lao Dao, and Lao Dao knows his own Dao, and he can still do it if he lives to be a hundred years old." "Okay, in that case, Chief Sun, you should pay attention to yourself."

is worthy of Sun Simiao Sun Divine Doctor, and then Yang Heng directly gave him the needle and asked him to operate, he actually completed Yang Heng's steps meticulously, this is the real doctor.

"Xiaoyou, shouldn't it be injected subcutaneously next, this person shouldn't be allergic." "Well, I think so." If you want to say that Sun Simiao can do it, it is much more skilled than Yang Heng, let Yang Heng do it, it is really too stupid, he pricked Sun Simiao's arm with blood before, and Sun Simiao, whether it is a skin test or a subcutaneous injection, it is all done in one go, and this injured person doesn't even feel anything.

"Sun Daochang, this, how did you do it, why can't I do it." "Hehe, this, Lao Dao can do dry needles, this is actually no different from dry needles, naturally, Lao Dao is very proficient." Lao Dao said with a smile.

Then he stopped talking, but carefully observed the wounded man in front of him. "Well, yes, this person's mental state is starting to improve, although there is nothing to see from the wound, but Lao Dao obviously feels that he should wake up soon."

"Oh, suffocate me, where am I?" Sure enough, it didn't take long for the wounded man to wake up with a loud scream, Yang Heng and Sun Simiao looked at each other and smiled, and succeeded. (To be continued......)
