After the aquatic father donated blood, with the support of the aquatic life, he had already gone home to rest.

Chen Yi hurriedly took the bottle containing blood into the house, a little dark room, Tiger Niu took her father's rough hand in the house, and gently stroked her cheek. The dog's mother looked at her husband with gentle eyes, she was a good person before hunting, how can she say that she was injured when she was injured?

Goudan held a long wooden stick, hurriedly ran in from the outside, the wooden stick is about two meters long, it looks like it was newly felled, it should be a locust tree, and there is a Y-shaped opening at the top of the stick, which is the dog Dan according to Chen Yi's requirements, so that it is convenient to wait for the blood transfusion.

When designing the blood transfusion bottle, I found a cloth strip that could fix the two ends of the bottle, threaded the cloth strip into it, and tied the threads of the cloth strip together, which could just fix the bottle in the groove of the wooden stick.

The doctor walked in with a plate containing a strip of cloth and many bits and pieces. Chen Yi originally planned to directly transfuse the dog's father without changing the needle, because he couldn't test whether the blood type matched, and the needle for blood transfusion was actually useless, for the sake of hygiene, he still changed the needle with a new one.

In the blood transfusion, there is a simple version of the flow regulator tied not far from the needle, Chen Yi opened the regulator to the maximum, and the doctor on the side was slow and confused, and asked Chen Yi what is the name of this thing? and other principles.

"This little thing, the master told me that it is called a flow regulator, as the name suggests, it is a small organ that can adjust the speed of blood transfusion, the principle of this organ is actually very simple, mainly controlled by a small ring inside, the groove on the outside, the smaller and narrower the lower it is, when the small ring is pressed down on the transfusion channel, it will make the runoff of its blood transfusion smaller to achieve the control effect." In order to let the doctor see clearly, Chen Yi asked the doctor to approach and observe carefully.

"Is there a requirement for a blood transfusion?" The more the doctor looks at it, the more he feels that such a thing, if it can be promoted, how many lives can be saved, God bless my Dayuan, God bless my Dayuan, Brother Chenyi must be God to see that our Dayuan is suffering, and he must be a messenger sent by God to save us.

"The speed of blood transfusion for people with different physiques will be different, children have to use small needles for blood transfusion because the blood vessels are relatively delicate, and the blood transfusion must be turned on the flow regulator to the slowest to prevent the blood vessels in the body from being harmed, and adults can use large blood transfusion needles, because the blood vessels of adults have been developed, and the blood vessels are relatively wide."

Blood vessels? The doctor thought for a while, and finally understood, because it is a pipe containing blood, so it is called blood vessels! I'm really a genius, no matter what, I must let Brother Chenyi promote this kind of life-saving device, and when I return to the palace, I won't let the five bodies admired by the imperial doctors fall to the ground. Thinking that the imperial doctors were going to bow down to their artifacts, the doctor laughed as he thought, and transparent liquid flowed out of the corners of his mouth.

"Doctor? How did you? Hu Niu looked at the doctor who was smirking, and couldn't help but pull the doctor's placket, and the doctor hurriedly wiped his mouth with the placket. His face couldn't help but turn red.

There was already blood left out of the needle, dripping in the bowl, Chen Yi thought to himself that the air in the blood duct should be drained, Chen Yi closed the flow regulator to the bottom, and the blood in the needle stopped flowing out.

took out a white cloth, tied it to the wrist of the dog's father with a white cloth, clenched his hand into a fist shape, Chen Yi gently patted the surface of the fist, looked at the back of the palm with a slight burst of blood vessels, and could clearly see it on the back of the hand, clamped a white cloth strip with tweezers, dipped in some wine in the bowl containing wine, wiped the surface of the back of the hand clean, slowly inserted the needle into the blood vessel, and finally fixed the needle on the back of the hand with a cloth strip, and pushed the flow regulator on the blood vessel to the middle position, which can be vaguely seenRed blood in the chicken intestines is slowly pouring from the bottle into the dog's father's big body.

Looking at the doctor on his side, he told him clearly the mystery and principle, and his precautions, the doctor jumped up and patted his thigh, and excitedly said some compliments, and the people outside the courtyard also returned home under the persuasion of Chen Yi.

Chen Yi took the wooden stick in his hand and asked the dog to take out the contents of the pot outside and put it on a clean plate for later use.

When the blood transfusion was finished, Chen Yi pulled out the needle, and the doctor couldn't wait to take the thing from Chen Yi's hand, and took it in his hand to observe it carefully.

The heart of the dog Dan family seems to jump out, wandering, wandering but unable to find an exit, only knowing that they will face the most anxious moment of their lives, their hearts are pounding, their hearts are going up and down, and their mood is not calm like a turbulent lake.

Chen Yi walked out of the house, I don't know when the sky was full of dark clouds, as if it was about to rain heavily, Chen Yi's heart could also rain happily, let the rain wash away all his unhappiness in this world.

"Brother Chenyi, I have a reluctant request, I hope Brother Chenyi can agree."

The doctor in the town, looking at Chen Yi who was standing at the door in a daze, thought for a while and still insisted on his teeth and planned to tell Chen Yi what he thought in his heart, after all, it was related to thousands of people, and it was also related to the blood and sweat soldiers guarding the frontier, and the happiness of thousands of families.

The doctor in the town told Chen Yi everything in his heart, Chen Yi didn't think about it, and agreed to the doctor's request, Chen Yi couldn't bear to let the soldiers sacrifice like that because of the backward medical conditions, they didn't get good treatment, and they couldn't bear to let the white-haired people send the black-haired people, and they couldn't bear to let a complete family be broken like this.

The doctor in the town, after hearing this, put his hands together, bowed deeply to Chenyi, and then said a word of thanks, and also told Chenyi his true identity.

Chen Yi only knew that the original doctor in the town was surnamed Huang, the imperial doctor of the imperial court, and he came to the town just to go home to save his relatives, and he was going to return to the imperial capital in a month's time, and invited Chen Yi to go to the imperial capital with him and introduce him to the current emperor.

"Brother Chenyi, my father woke up, come and see, come and see." The dog ran over excitedly laughing and crying, and said to Chen Yi with his hands dancing.
