Summer is coming, and Lianhai City has entered the rainy season.

After the summer solstice, it rained lightly for two days in Lianhai City, and the sky finally cleared up on the evening of the third day.

The staff of the Marina Hospital, which is located by the sea, are leaving work one after another, and only a few doctors on duty are still at their posts.

Xiao Chen of the laboratory department was on the night shift today, and he began to deal with the work after handing over to his colleagues.

Xiao Chen, named Chen Yaozu, is 23 years old this year, and has just entered the hospital to work after applying for a job.

The night shift is relatively easy, with only the occasional blood routine for a few emergency patients.

The blood collection tube was put into the centrifuge, pressed the start button, and listened to the centrifuge start to hum, Xiao Chen watched videos and dramas with his mobile phone while staying by the centrifuge.

"Bang ......"

There was a sudden crunch in the centrifuge, followed by the sound of rumbling debris hitting the inner wall of the centrifuge at high speed.

Xiao Chen came back to his senses from the video and chuckled in his heart.

Not good, listening to this sound should be the centrifuge tube broken.

Xiao Chen hurriedly pressed the stop button, and the centrifuge that was rotating at high speed slowly stopped.

When I opened the lid of the centrifuge, it was a mess inside.

The rotor inside the centrifuge is still spinning at a low speed, the inner walls are blood-red everywhere, and there are many debris from the blood collection tube at the bottom.

Alas, this happened again.

Xiao Chen felt that his head was big, the centrifuge of the laboratory department was broken before, and he temporarily found a spare one from the warehouse, but the centrifuge tube of the centrifuge was not very compatible with the blood collection tube used in the current laboratory department, and the centrifuge tube wall was much longer than the blood collection tube, and the blood collection tube should be completely put into the centrifuge tube wall before the centrifugation began, otherwise the centrifuge tube cap would often be stuck on the outer edge of the centrifuge tube wall, and the blood collection tube would rupture in the case of high-speed centrifugation.

Two days ago, he just made the same mistake, before putting the blood collection tube into the centrifuge, the cap of the blood collection tube was stuck on the stainless steel tube wall of the centrifuge, resulting in high-speed centrifugation, the cap of the blood collection tube fell off, and the tube body hit the centrifugal arm and shattered.

During the night shift, there was no one else around, and Xiao Chen wanted to cover up this matter, so he found the patient who was waiting for the results at the door of the laboratory department to collect blood again, and cleaned up the slag of the blood collection tube in the centrifuge, and sprayed the centrifuge with alcohol to disinfect the centrifuge.

On the second day of work, no one noticed anything unusual.

In the first few days, Xiao Chen was still apprehensive and always worried about concealing his experimental mistakes, but after a few days or even more than a month, everything was normal, and Xiao Chen himself gradually forgot about it.

On Saturday, Xiao Chen asked his girlfriend to come to the house for dinner.

Xiao Chen's father died in a car accident when he was very young, and he has been living with his mother, and he met his girlfriend Xiao Zhang when he was in college.

The two have been in love for four or five years, and their mother urged them to get married.

Chen's mother is a typical housewife, she pulled her son to grow up alone, and now her son works, and she also retires from the workplace, but she is not idle, and after retirement, she found a cleaning job to help her son save for a down payment to supplement the family.

Chen's mother cooked a table of good dishes, and at the dinner table, she talked to her son and future daughter-in-law about whether they had a good house and how much they needed for a down payment.

Xiao Chen: "Mom, you don't have to worry about the house, Jingjing and I can solve it by ourselves." ”

Chen's mother: "How to solve it yourself?" How much money can you both save when you just start working? Now that the house price is so expensive, buy an ordinary 3 bedroom and 2 living room house in our coastal area, and the down payment is at least 600,000 yuan. ”

Xiao Zhang: "Auntie, I have discussed with Yaozu, there is no need to buy such a big one, let's buy a 2-bedroom and 1-living room house to live in." ”

Chen's mother immediately objected, "How can that work?" The house with 2 bedrooms and 1 living room is too small, and there will be children who can't live in the future, and now the two-child policy has been released, at least two children, so if you want to buy it, you can buy 3 bedrooms and 2 living rooms, once in place, I will help you out with the down payment. ”

"Mom, if you give us a down payment, we are gnawing at the old." Xiao Chen said with a smile.

"Ahem, cough, cough ......" Chen's mother didn't know if it was because she was emotional or something else, she coughed one after another, and finally endured it before she continued, "Aren't they all like this now?" The old one helps the younger one make a down payment, and the two of you repay the loan yourself. If you are allowed to save for a down payment, when will you be able to buy a house and get married? Now this is basically the case in our city, if it is in the countryside, the parents also have to build a good house for their son, and marry a daughter-in-law to fulfill their responsibilities. You don't have to be embarrassed, I'll take care of your children when you have children in the future, cough cough cough ......"

Xiao Zhang hurriedly patted her future mother-in-law on the back and asked worriedly, "Auntie, what's wrong with you?" Coughing so badly, you weren't like this the last time you came. ”

Xiao Chen also came up to pat his mother on the back, and at the same time complained and worried, and said, "Mom, I told you last time, don't go to work part-time, take care of it at home when you retire, and go to square dance with the neighbor's aunt, quit the cleaning job you were looking for, it's too tired." ”

Chen's mother steadied her breath, "That job was introduced to me by a sister of mine, doing cleaning work in the Grand Theater, it's very easy, and you can listen to their newly rehearsed opera for free, this job can't be done by others......

Before she finished speaking, Chen's mother coughed violently again, and this time she covered her mouth with her hand to prevent the coughed droplets from splashing on the table in front of her.

Xiao Chen stretched out his hand to test Chen's mother's forehead, and the temperature was a little high.

"Mom, you have a fever?!"

Chen's mother touched her forehead, "It seems to be a little, I was drenched in the rain when I came back the night before, maybe I caught a cold." ”

Xiao Chen found a thermometer from the drawer and measured it for his mother, 37 degrees 6, and it was indeed a low-grade fever.

Chen's mother started coughing in the past two days, and now she has a low-grade fever again.

"Mom, come with me to the hospital tomorrow for a check-up." Xiao Chen asked.

"You don't need to go to the hospital for a small cold, just take some cold medicine yourself, tomorrow weekend, you and Xiao Zhang go to see the house, I won't go, I still have classes on the weekend, come back and tell me after I see it."

"Mom, the cleaning work of the Grand Theater is too tiring, I have to go on weekends, and I only have 4 days off a month, you might as well quit, you see that I am also working now, and I can still give you living expenses every month."

"Your mother, am I the one who can be idle? Say no more, you guys go to see the house tomorrow. ”

"Oh, Mom, do you still have cold medicine at home?"

"Yes, you brought it back last time, and you haven't finished it yet."

Xiao Chen knew his mother's temper, once she decided that it was difficult to change, Xiao Chen no longer persuaded her, and on the weekend, according to Chen's mother's request, the two young people went to see the house, and Xiao Chen's mother rested at home.
