Zhang Liang did not go to Qin Dada again. Since he decided to find out the truth of the matter, he would not do anything to cause trouble for himself.
He first found the little nurse who had helped him change his dressing before. The little nurse opened her mouth when she saw him, and said in shock: "No, here you go again? You just left and disabled yourself again?"
Zhang Baobao rolled his eyes angrily and said helplessly: "Don't make trouble, I have something to ask you."
The little nurse looked at Zhang Badan suspiciously and saw that he was not joking, so she asked, "What's going on?"
Zhang Liang asked seriously: "I want to ask you if you know anything about the old beggar you sent to the hospital before."
The little nurse didn't expect Zhang Liang would ask her this. She said with some confusion: "Why are you asking him? It seems that his condition suddenly worsened last night and he died without resuscitation, eh? By the way, I remember it seemed like last time
You just asked me about this person, you don't really have anything to do with him, do you?" After saying that, he looked at Zhang Baoan with suspicion.
Zhang Baolian's eyes lit up after hearing this, and he asked, "Then can you tell me the specifics of what happened yesterday?"
The little nurse was a little surprised as to why Zhang Liang was so interested in this matter, but it was obvious from the look on his face that he had no intention of answering her questions, so she had no choice but to say: "I don't know much about the specific situation. The person responsible for caring for that patient is
, I only know that it seemed that at midnight last night, for some reason, the emergency call button in the ward rang, and when the doctor on duty rushed to the ward, he found that he had died. That's all I know."
Zhang Baoli was a little confused after hearing this, and then asked: "What about Mrs. Qin? Isn't she taking care of her in the ward?"
The little nurse shook her head and said: "Then I don't know, but it seems that Dada was not there when the doctor arrived. He came back after a while. Maybe he went to the bathroom. Who would have thought that it would only take such a while?
, this will happen.”
Zhang Liang did not fully believe what the little nurse said, but he didn’t say anything more. He just said thank you and planned to leave. The little nurse asked curiously: "Why are you asking about this? What relationship do you and him have?"
What’s the relationship?”
Zhang Liang did not answer her. When he was about to go out, he suddenly turned around and asked: "By the way, I have another question. Do you know the cause of his death?"
The young nurse thought for a while and said, "I actually heard this from another nurse who was present yesterday, saying that the cause of death seemed to be suffocation."
Suffocated? Zhang Baoan nodded and left.
The little nurse looked at Zhang Liang's back and murmured in a low voice: "It's strange that this man is so interested in an old beggar. Could it be that he is his long-lost second uncle?" As he spoke, he was amused by his own thoughts.
.
Zhang Liang did not know that the little nurse complained about him. At this moment, he was reviewing in his mind the news he had just heard from the little nurse. When the old beggar had an accident, Mr. Qin was not sure whether he was in the ward. The doctors saw him in the ward.
He only rushed over after receiving emergency call instructions, which led to two completely opposite directions of development.
If Qin Dada was in the ward, she would not have watched the old beggar die before calling out, unless she was the one who wanted to harm the old beggar.
And if Mr. Qin was not in the ward, then either the old beggar himself pressed the emergency button because his injury suddenly worsened, or a third person appeared in the ward, murdered the old beggar and then pressed the button to call the doctor.
No matter how Zhang Liang thought about it, he felt that the second scenario was impossible. First of all, just talking about the old beggar himself, with his sanity, even if something happened to him, he might not know how to press the emergency button to call a doctor.
; Secondly, if there is a third person who wants to harm the old beggar, then he can completely escape immediately after harming the person. There is no need to press the emergency button to call the doctor. Firstly, someone may catch him committing the crime, and secondly, if the doctor comes
After giving first aid to the old beggar and reviving the old beggar, wouldn't his work be in vain? For him, it would be more advantageous for him to let the old beggar's death be discovered as late as possible.
Judging from these two points, the second hypothesis can basically be eliminated, leaving only the first hypothesis, which is that Qin Dada was always in the ward.
But if Qin Dada had been in the ward, why didn't she call the doctor as soon as the old beggar was in trouble? If she had acted quickly, the old beggar wouldn't have died before the doctor arrived. Could it be, really
Did she deliberately want to kill the old beggar?
Thinking of this, Zhang Badan suddenly felt a tightness in his chest. He really couldn't imagine the reason why Qin Dada did this. It seemed that if he wanted to find out the truth of the matter, he could only go to Qin Dada and ask him face to face.
So, Zhang Badan walked to the nurse's station where Qin DaDa usually stayed.
Along the way, Zhang Bao thought about a lot of things to say, thinking about how to say something that would not make Daddy Qin angry, which made him feel a little bit of a headache in the end. However, when he came to the nurse station, he found that he still thought too much, because Daddy Qin had no idea at all.
Not there.
Zhang Liangliang breathed a sigh of relief unknowingly. He didn't know when he started to be afraid of facing Qin Dada and communicating with her. Maybe it was because he couldn't get over the hurdle in his heart. Although Qin Dada is not here now, his
His questions were not answered, but Zhang Liang felt somewhat relaxed.
He pushed open the door of the nurse's station and walked in, found a chair and sat down, closed his eyes and rubbed his face, and began to sort out the clues in his mind.
The little nurse said that the old beggar died of suffocation. Although Zhang Baobao is not a medical student, he also knows that human breathing is achieved by lungs. Speaking of lungs, Zhang
The bad guy suddenly thought that Mr. Qin had said before that the old beggar’s lungs were also injured and there was severe fluid accumulation. Could it be because of this? But didn’t it mean that all the fluid in the lungs had been drained out? Or was it that the lungs had accumulated fluid?
The fluid does not only need to be extracted once, but needs to be extracted at any time? If this is the case, could it be that Qin Dada did not help the old beggar remove the fluid from his lungs in time, which caused him to suffocate?
Thinking of this, Zhang Liang stood up and started to scan around the nurse's station, wanting to see if there were any syringes or anything like that. But as soon as he took a look, he stopped, and then smiled to himself, because he thought
, even if I find it, what's the use? Firstly, I don't know how it works. Secondly, even if I have this thing, I can't tell whether it was used last night.
Thinking about it, Zhang Baoan sat down again. At this time, he suddenly thought of someone.
This person’s name is Song Dongxi, a classmate of Zhang Liangliang’s in high school. At that time, the two were at the same table and considered best friends. Because his name sounds similar to “delivery”, there was also a “courier” in the class.
nickname.
Later, after passing the college entrance examination, Zhang Badan was admitted to a university in City S to study mechanics, while Song Dongxi was admitted to a medical school in City Z to study medicine. After graduation, Song Dongxi returned to their hometown of Q City and became a doctor. Although it took a long time
It hasn't been long yet, but it seems to be doing well now.
When he thought of him, Zhang Liangliang felt his eyes light up instantly. Yes, besides Bai Jingwen and Qin Dada, he also knew a person who was studying medicine. If there were many questions he didn't understand, just ask him.
So Zhang Baoan immediately took out his cell phone, found Song Dongxi's number and dialed it.
Although the two of them have not been in the same area for four years, they get together every time they return to their hometown during the winter and summer vacations, so their friendship is not far apart.
Soon, the other end of the phone was connected, and a voice that sounded a little bit ruffian came over: "Hello! Xiao Liangzi? Why are you calling me now?"
Zhang Liang was a little happy when he heard his friend's voice. He replied: "I just met a courier and I thought of you. I just wanted to give you a call to say hello!"
The two chatted on the phone for a while. After chatting for a while, Zhang Baoan finally remembered the business and asked: "Hey, let me ask you something. If a person has fluid in his lungs, how should he treat it?
Can it be cured in one go?”
Song Dongxi said in surprise: "What's wrong? Are you sick?"
Zhang Liang scolded: "Get out! I'm healthy, but someone I know has this disease, so I'm asking you."
Song Dongxi said: "Oh, but you asked the wrong person when you asked me, and I don't know either!"
Zhang Liang was surprised and said, "You're a medical student and you don't know this?"
Song Dongxi said helplessly: "Brother, those who study medicine are also divided into majors, okay? I studied testing, not clinical practice. How can I understand this!"
Zhang Liang was a little disappointed and had no choice but to say: "Okay, I didn't ask!"
Song Dongxi may also feel a little embarrassed, and said: "But I can help you ask. I have a friend who is in the clinic. The leader of their department is the director of clinical medicine. I can ask him, or let him ask for you.
."
Zhang Buli thought, another director? I have a director here, and he might still be my father-in-law! But he still said: "Thank you, by the way, ask your friend, if the effusion is not drained out, what will happen?"
It will not cause death by suffocation."
When Song Dongxi heard this, he was immediately confused. He asked: "Why am I a little confused? Didn't we just talk about the problem of fluid accumulation in the lungs? Why did it turn into suffocation and death now? Are you like this?
The more you talk about it, the more terrifying it becomes! Brother, you must be in trouble!"
Zhang Baoliang couldn't help but smile bitterly when he heard the somewhat exaggerated voice on the phone. Did he get into trouble? Speaking of which, it really had nothing to do with him. If he was to blame, it was his damn curiosity and that
The so-called "sense of justice" does not mean that the trouble is caused by him, but that the trouble is caused by him.
Zhang Liang hesitated again and again, but decided to tell Song Dongxi what happened. He briefly told Song Dongxi what had happened since he met Song Jiao and suffered a car accident. After hearing this, Song Dongxi was so surprised that he couldn't open his mouth from ear to ear.
After Zhang Liang finished speaking, he sighed helplessly and said: "Originally, you know my character. I have to take a detour when encountering a dog. But this time, for some reason, I just can't get over it!"
Song Dongxi also said with some disbelief: "You don't even dare to write about your experience in a novel like this. It's too weird. Oh no, it's too nonsense! Why do you think you, a man in science and engineering, are getting involved in these things!"
Zhang Liangliang didn't seem to want to discuss this topic any more, so he could only say, "Anyway, you can ask for me, just think it's just my free time, just playing around."
Song Dongxi sighed and said: "Come on, let me ask you first, and I will tell you when there is news." Then he was silent for a moment, and then continued in a serious tone: "Hey, I said, you can take it easy.
, don’t play yourself into it!”
Zhang Baolan felt warm in his heart and said with a smile: "Don't worry, don't you understand me? I'm very timid!" The two chatted for a few more words and then hung up the phone.
Putting away his cell phone, Zhang Badan was about to leave. Anyway, there wouldn't be any new progress if he continued the investigation today. The moment he turned around, something suddenly came into his eyes, making him stop.
It was a ventilator, placed in the corner of the nurse's station. Half of the machine was blocked by other things. If you didn't look carefully, you wouldn't even notice its existence.
The moment Zhang Liang saw it, a bold idea popped into his mind - could this be the ventilator that the old beggar used before he died?
This idea suddenly excited Zhang Badian. The more he thought about it, the more likely he felt that this was a possibility, so he quickly walked over and took a closer look.
In fact, Zhang Badai's idea is very simple. Since the old beggar suffocated to death, it is nothing more than a human problem on the inside, and a machine problem on the outside. Since the human problem cannot be explained clearly, let's check if there is a problem with the machine.
!
Zhang Baoli pulled the ventilator to a spacious place and looked at it carefully with his butt raised. However, he soon became disappointed again because he found that he could not understand how this thing was used at all!
For something you don’t understand, you may not understand what it does even if you think about it all your brains. But fortunately, Zhang Baobo’s mechanical knowledge comes in handy at this time. Although the working principle of the ventilator
He didn't understand it, but he slowly figured out the mechanical structure.
To put it simply, it consists of an oxygen supply device and a tube that transports oxygen. At least in Zhang Liang's eyes, he can only see these things.
The tube that transports oxygen is made of something similar to a rubber tube. There are two tubes connected to the oxygen supply device. Zhang Zaobao studied for a long time before he figured out that one was an exhalation tube and the other was an intake tube.
Later, the two tubes are combined into one, and finally there is a mask, which is used to fasten to the patient's face. A more vivid expression is a Y-shape.
Zhang Baoyou looked at it for a long time and felt that he couldn't tell anything just by looking at it, so he decided to find a power socket and turn it on to give it a try.
He looked around and found that there was a power strip under the computer on his desk. He carried the ventilator to the computer desk, plugged in the ventilator, and heard the machine immediately beep.
.
Zhang Boi looked at the oxygen supply box. There was a small screen and a few buttons on it. The screen was now on. There were several numbers written on it, which were probably values such as temperature, humidity, and air pressure. Zhang Boi thought, what?
How can I make this thing vent its anger? Is it possible to vent its anger just by taking it with me?
He tried pressing a few buttons, but there was no response. At this time, he discovered that there was a rather large knob next to these buttons. What was it for?
Zhang Baoyou tried to twist it, and suddenly, the ventilator made a gentle "buzz" sound, and then started to work.
Done! Zhang Baoan thought to himself. He picked up the end of the mask and gently covered it on his palm. He immediately felt a gentle airflow blowing out.
Huh? It seems that the ventilator should be fine, which means that the old beggar did not suffocate due to the ventilator.
Zhang Baojun sat down on the ground, looking a little frustrated. He tried all the clues he could think of, but in the end he still found nothing. A deep sense of frustration came over him in vain. He even felt that he was so persistent in trying to figure it out.
You know this is a stupid act.
After feeling sorry for himself for a while, Zhang Badou stood up again and tried to turn off the breathing machine and put it back on. However, he might have gotten up too hard and the blood supply to his brain was insufficient. He stumbled and almost fell down. His hand accidentally touched the oxygen supply connector.
The air pipe on the device box suddenly made Zhang feel that the mask in his hand seemed to have no air flow!
At first he thought the gas pipe had been knocked off, but when he looked carefully, he saw that the gas pipe was still well connected to the oxygen supply box. What was going on?
Zhang Badai quickly checked the tube carefully. There was no problem with the tube from the mask to the connection part of the Y-shaped tube. There was also no problem with the exhalation tube end of the Y-shaped tube. However, when inhaling
At this end of the pipe, Zhang Baoli discovered that there was a crack about one centimeter long near the root of the pipe!
At first glance, this crack was made artificially. Because it is too close to the root, the hardness of the pipe makes the crack completely closed at ordinary times. Therefore, there is almost no air leakage under normal use. However, due to poor tension, I pulled hard just now.
The crack is forced to open, so the gas immediately leaks from the crack, so that there is almost no gas output from that end of the mask.
It turned out to be like this! There was a burst of ecstasy in Zhang Baoan's heart, and finally he discovered the clue. Now it can basically be concluded that the problem lies with this machine. As long as one more thing is proved, the old man can basically be found out.
The cause of the beggar’s death is to confirm that this ventilator is the one the old beggar used before!
How to prove this? Zhang Baolan's brain was working at a rapid speed. It has been less than 24 hours since the old beggar died in the middle of the night yesterday. Generally used ventilators must be disinfected, and masks and even air tubes that come into contact with patients must be disinfected.
They must all need to be replaced, and this ventilator is placed in the corner like this. Obviously, it has not had time to perform these operations. The cracks on the tube also prove this. This is the most powerful evidence! So,
As long as data such as the old beggar's fingerprints or DNA can be extracted from the mask, it can be proved that the user of this ventilator is the old beggar!
Zhang Liang felt that his thinking was extremely clear now, and he made a decisive decision. No matter what, the tube and mask must be taken away!
So he got up and wanted to turn off the ventilator, and then find a way to remove the tube. But after searching for a long time, he couldn't find the switch. Finally, he was cruel and unplugged the power strip.
Come down.
However, the next moment, the piercing alarm sounded in vain in this empty nurse station!
