Conan: The Mechanic

In the afternoon, Qianyu was making spare arrows for Wuhen Umbrella when she suddenly heard a phone call.

"Qianyu?" Hoshino Kaede's voice came, sounding very weak. "Open the back door of your house...the back door..." He hung up the phone after saying that.

"?" Qian Yu was in a daze, but saw a light on the board next to the workbench come on.

This light is connected to an infrared sensor system at the back door - does Kaede Hoshino mean that he is at the back door?

Qianyu hurriedly came to the back door, looked at the backyard iron gate from the optical cat's eye on the door, and saw Hoshino Kaede kneeling against the iron gate.

Why is he here? The front door is unlocked, why doesn't he go to the front door?

"Hoshino?" Qianyu quickly opened the back door and ran over. "What’s wrong with you?"

Hoshino Kaede did not respond to him.

Chiyu touched Hoshino Kaede's nose, and after confirming that he was still breathing, he immediately opened the iron door and dragged Hoshino Kaede into the house.

Chiba had never seen Kaede Hoshino in such a state—in fact, the term changed to "human" is completely valid—so he chose to ask for foreign aid.

"Do you have a sphygmomanometer at home?" Gregory said, with his legs on the table and half lying on the armchair. "measure it."

A minute later, Qianyu measured a reading of 60/40—70 was systolic blood pressure and 40 was diastolic blood pressure, both of which were far below normal values, and even far below normal low blood pressure values.

"Does your friend have a history of hypotension before?" Gregory snorted and continued to ask. "Is there any disease related to blood vessels? What is the disease state?"

"As far as I know, there is none. The state of the disease is unknown, but it should be a sudden discomfort while walking."

"Have you run out of norepinephrine (now called norepinephrine.) in the luxury home medical kit you bought from Cornflower Central Hospital?"

"It hasn't been consumed."

"Remember the injection technique I taught you?"

"Eh..." Qianyu blushed. "Remember..."

Some time ago, when Qianyu went to review the gunshot wound in the Takeda Shingen treasure case, she was pulled by Gregory, who was understaffed by nurses, to go to the top shift and learned painless injections by the way - at the cost of a nurse who made a mistake. The cost of a few pinholes and a dessert.

"Give him a shot of norepinephrine, remember to add normal saline to dilute to 10 ml," Gregory's voice relaxed. "It's just low blood pressure, and it's probably caused by too much antidepressant."

"Anti-depressants?" Qian Yu confirmed with a frown as she went to get the family medical kit. "You mean he's on antidepressants?"

"It may also be a sedative or antihypertensive drug," Gregory said leisurely. "But sedatives are generally out of reach, and antihypertensive drugs are not for people who don't have vascular-related diseases -- heart disease. Considering the current economic downturn in Japan, aren't antidepressants a very reasonable explanation?"

"Uh... well, let me confirm..." Qianyu came to Gregory with the medicine box, and was suddenly stunned when she looked at the epinephrine bottle in the medicine box. "Is it epinephrine or norepinephrine?"

"Norepinephrine!" Gregory's voice suddenly became severe. "Hiting epinephrine will strengthen the beta receptors, resulting in lower blood pressure, which will kill him!"

"Understood," Chiyu turned on the hands-free mode, took out a pair of plastic gloves, and then took out a norepinephrine canister and a saline canister. "The pharmacology of epinephrine is to activate both alpha and beta receptors, but because of the drug-induced blockade of alpha receptors, epinephrine primarily activates beta receptors - which causes vasodilation and further lowers blood pressure. So it must be Alpha receptors are stimulated alone using norepinephrine, which primarily activates alpha receptors and blocks beta receptors."

Insert norepinephrine and saline into a disposable syringe with a blunt needle at the end of the pusher plug, and install a new set of disposable needles on the syringe, so that a ready-to-use norepinephrine injection tool is installed Done.

"It sounds like it's ready," Gregory's voice came from the phone. "Do you remember why the pusher of the syringe is so long?"

"In order to puncture the plastic tube and facilitate the mixing of the medicines inside," Qianyu pushed the syringe down, the blunt needle immediately pierced the saline tube and the norepinephrine tube, and the two liquids immediately mixed. "The vein is shot at a low speed, the included angle is 30 degrees, and the needle penetrates two-thirds of the way - oh!"

Chiba suddenly picked up the alcohol bottle in the medicine box and sprayed the back of Hoshino Kaede's hand a few times. "I almost forgot to disinfect it just now..."

After disinfecting, Chiba grabbed Hoshino Kaede's hand and found the vein on the back of her hand without much effort. "found it..."

The needle accurately pierced the vein in the area covered with alcohol, and slowly injected the drug into Hoshino Kaede's vein - although it was slow, it had already surpassed the most commonly used intravenous drip of norepinephrine. Speed, direct injection is just to ensure that Hoshino Kaede lives without worry.

"Okay, this needle should last until the ambulance arrives~www.NovelMTL.com~ Gregory's voice became more leisurely again." Open the door, so that when the medical staff arrives, it is easier to carry people directly. car. "

After speaking, the phone hangs up.

When Chiba opened the door and the iron door together and walked back, he found that Hoshino Kaede had opened his eyes.

"Looks like I'm still alive..." Hoshino Kaede said weakly.

"You're still alive mainly because I still have norepinephrine to play here," Qianyu frowned. "You're basically safe when the ambulance arrives."

"Thanks to you for saving my life..." Hoshino Kaede smiled bitterly.

"By the way, are you taking antidepressants?" Qianyu suddenly remembered what Gregory had said before and asked.

"No!" Hoshino Feng was stunned.

"Your blood pressure is 60/40," Chiba showed Kaede Hoshino the previous results on the sphygmomanometer. "It's clearly not normal."

"I was thrown by my prey before..." Hoshino Kaede shook his head helplessly. "I'm careless. The tea that guy handed me probably contained a large dose of sedative. I felt something wrong on the way home, and I tried my best to get to you..."

"The tea handed to you?" Qian Yu raised her eyebrows. "Your relationship is so good, but you want to hunt him down? You won't be carrying out the task of the inspection team, will you?"

"No," Hoshino Kaede shook his head. "I was in trouble when I was helping Haiyuan Ai to deal with the identity issue. The guy who was originally with me and didn't make the river water set me up."

At this moment, the phone rang again—the caller was Ai Haibara.

As soon as the phone was connected, Haibara's anxious voice came over.

"Qianyu, Mr. Hara was killed!"

In the distance, the sound of an ambulance sounded.
