Cities: from Heavy Locomotives to Industrial Overlords

Lu Junyi complained, and her eyes fell on an ambulance not far away.

beep... beep... beep... beep...

The warning lights of the ambulance were flashing all the time.

There was a traffic police car in front of the ambulance, and the lights of the police car were flashing all the time.

In such a situation that the front and back are blocked for several kilometers, it is not that the driver will not give way, but that there is no place to give way at all.

Even if he moved out a little, the ambulance couldn't get through at all.

It was an ambulance and a traffic police car. Obviously, the ambulance was carrying patients or important medical supplies.

Unfortunately, this viaduct has no emergency lanes.

The entire line of traffic jams can't move, and the traffic police can't do anything about it!

Just be in a hurry!

After hesitating for a moment, Lu Junyi opened the car door, looked at the traffic jams that had no end and no end, and then walked to the ambulance and the traffic police car.

beep... beep... beep... beep...

The warning lights of the ambulance are constantly flashing, which means that there are lives waiting for first aid.

At this time, a middle-aged policeman also got off the traffic police car.

The middle-aged policeman looked at the long traffic jam, and was very helpless. He could only keep going through the walkie-talkie, hoping that the headquarters could arrange for an iron rider to come and help as soon as possible.

Lu Junyi came over, looked at the middle-aged policeman, and said, "Police, may I ask, what's the situation?"

"Is this ambulance transporting patients waiting for first aid?"

The middle-aged policeman said, "No."

"The ambulance was loaded with panda blood waiting to be rescued."

Panda blood is also Rh-negative blood, and Rh is the first two letters of the foreign name of Rhesus-Macacus.

Human red blood cell blood group consists of more than [-] blood group systems, ABO and Rh blood group are the two blood group systems most closely related to human blood transfusion.

When there is a D blood group substance (antigen) on a person's red blood cells, it is called Rh positive, which is expressed by Rh (+); when there is a lack of D antigen, it is Rh negative, which is expressed by Rh (-).

Human blood type is usually determined by antigens composed of certain heritable glycoproteins and sugar chains on the surface of red blood cells.

Existing scientific research has found that RhD-positive people account for the vast majority of the world's population, and RhD-negative is very rare.

For example, in Asia, more than 99.5% of people are RhD positive, and less than [-] in [-] people are RhD negative, so it is called "panda blood".

"The No. [-] Hospital of Donghai City was bleeding heavily when the baby was born. The blood type of the pregnant woman is RhD negative, which is panda blood. Therefore, the No. [-] People's Hospital of Donghai City asked the Donghai City Blood Management Office for help. The blood bank urgently called a batch of pandas. The blood went to the Third Hospital of Donghai City."

"But I didn't expect to be blocked in the middle of the road, hey! Life!"

For people with panda blood type, there are three methods of blood transfusion.

One is to donate through well-meaning people who are also "panda blood".

The second is that the patient draws his own blood in advance in case of emergency.

The third is a one-time emergency input of RhD-positive blood.

However, the third blood transfusion method does not have much effect on the panda blood personnel, and can only be used in an emergency.

Bleeding during pregnancy?

This made Lu Junyi's heart skip a beat!

Worried!

This... a little careless, is one corpse and two lives.

It's not easy for a woman!

Every time you give birth to a baby, you are wandering between life and death, and you are going through hell.

Especially for a woman with this panda blood type, it is even more great.

Because once there is heavy bleeding, the lack of Rh-negative blood may be dead in minutes.

Donghai City is an international metropolis, and has always been active with loving volunteers with Rh negative and A blood types. Therefore, Donghai City has established an unpaid blood donation volunteer alliance for Rh negative rare blood types and A blood to collect panda blood for emergencies.

In other cities, there may not be panda blood.

Even so, the supply of panda blood is in short supply, and the demand for Rh negative blood cannot be met in time.

This pregnant woman is lucky.

Because when she needed panda blood, there happened to be a stock of panda blood in the blood bank.

But she was unfortunate.

There was a big traffic jam when the blood was being transported.
