I can extract side effects

"President Lu, start the machine!"

Everyone looked at Lu Tingfeng eagerly.

This exciting moment, like the button to launch a rocket, has to be completed by the leader.

"Okay." Lu Tingfeng laughed, took the portable defibrillator without hesitation, plugged it in, and pressed the power button.

Sanqing's logo flashed by, and it took only a second to enter the work interface.

The defibrillator is different from other equipment, and the faster the startup speed, the better.

The patient's heart has stopped beating, and rescue needs to be started immediately. If it takes 30 seconds to turn on the device at this time, the doctor will already start smashing the device.

At first, there are no parameters on the screen, only a wizard icon that shows how to use the defibrillator for first aid.

"Who will be the first to try?"

Lu Tingfeng installed the electrodes, glanced around, and asked.

Of course, he didn't want to give normal people a random test, but to test the detection effect of the electrode pads.

One end of the electrode sheet can be inserted into the interface on the back of the device, and the other end is two patches that can be attached to the chest and back for ECG detection and analysis. Only when a patient's cardiac arrest is detected can defibrillation be performed.

If it is a normal beating ECG, it is impossible to use the machine for defibrillation, so as to avoid misoperation to the greatest extent.

This is very important for defibrillators.

You know, people in cardiac arrest can use a defibrillator, but if a normal person is electrified, the power may be lost immediately.

Because the defibrillation shock is equivalent to giving the heart a restart command. If a normal person receives an electric shock, if the shock falls on the vulnerable area of ​​the myocardium, it will directly induce ventricular fibrillation, which is equivalent to stopping the heartbeat. .

This is a matter of life and death, and misoperation control must be done well.

Moreover, during the process of cardiopulmonary resuscitation, chest compressions usually affect the detection and analysis of the ECG. After the electrodes are attached, it can effectively avoid the interference of chest compressions on the ECG and improve the accuracy of heart rhythm analysis.

In this way, there is no need to reduce the number of chest compressions, but a two-pronged approach, defibrillation and compressions are performed together, and the patient can be rescued as soon as possible.

Soon someone volunteered, lay on the sofa bed, lifted his clothes up, revealing his entire smooth chest.

After the electrodes were attached, a detailed electrocardiogram appeared on the working interface of the portable defibrillator, and the analysis began.

At the same time, the voice of "Please do not touch the patient" is issued to guide the next step.

The special feature of the automatic external defibrillator (AED) is that it can automatically analyze the patient's signs and judge whether it is suitable for defibrillation, and if it is suitable, it can also automatically adjust the appropriate voltage.

In this way, even non-medical personnel can get started.

Obviously, this is a healthy person, so it was immediately concluded that defibrillation was not needed.

The defibrillation button is always gray, does not change color, and cannot be used.

Even the "one-button defibrillation" physical button on the side cannot be pressed down.

If it is a real cardiac arrest patient, the portable defibrillator will intelligently adjust the discharge power to perform automatic and precise defibrillation.

This reduces the defibrillation energy, greatly reducing the possibility of heart damage and skin burns.

Of course, manual defibrillation can also be selected so that detailed settings can be made using the "Defibrillation" button.

"Yes, security is still guaranteed."

Lu Tingfeng nodded in satisfaction.

Everyone checked the electrocardiogram again, and there was nothing wrong, so this step of the test was considered passed.

At this time, charging is also completed, and the battery indicator on the defibrillator turns green.

"Okay, then you can test the discharge function."

Lu Tingfeng tore off the electrodes, entered a code on the device, and entered the engineer mode.

This time the defibrillation button can be operated, and it will automatically discharge when pressed.

It is reasonable to discharge 200-400 times for a full charge to meet the requirements.

Of course, a discharge here must be calculated according to the lowest current.

"This is fun, I'll try it."

"I'm coming too."

Everyone tried the discharge operation one after another and had a great time.

"Ahem, everyone, don't forget to assemble a few more prototypes for testing, and find a CRO institution for animal clinical trials."

Seeing that a group of subordinates were having a good time, Lu Tingfeng ordered with a straight face.

After the registration of a third-class medical device such as AED, it needs to pass animal experiments and compare with similar products before it can pass the review and go on the market.

In terms of anatomical structure, the heart structure and blood circulation system of pigs are similar to those of humans, and the chest size is also relatively similar to humans, so animal experiments on defibrillators are generally carried out on pigs.

Different AED products will set different energy levels. Generally, 10 pigs are needed for each energy level, and 20 pigs are needed for 2 energy levels.

Sanqing's AED is a new product, and it needs to be compared with the products already on the market, so 40 pigs are needed. Each pig does 30 experiments, and at least 1,200 experiments must be completed before it can be used on humans.

Such animal clinical trials consume a lot of time and money, so it is no wonder that some equipment factories with insufficient strength want to take shortcuts.

But now pharmaceutical companies and device factories, if they have money, have already outsourced all these trivial and lengthy clinical trials to CRO companies.

The equipment team quickly installed ten prototypes for more stringent verification to ensure that all functions are correct.

Just at this time, a group of newly recruited engineers also arrived.

With a lot of extra manpower on hand, Lu Tingfeng divided into different project teams to tackle the four types of equipment simultaneously.

In addition to these four new projects, two old projects also need maintenance and continued development.

Moreover, Lu Tingfeng also had a new plan in mind. Since Sanqing's current equipment products are all portable, he wanted to build on this and gradually invest in manpower to develop professional equipment for hospitals.

Sanqing's existing portable automatic defibrillator (AED) is quite different from the professional defibrillator used in hospitals.

The defibrillator in the hospital is the kind that people often see on TV. When the doctor rescues the patient, he holds something like an electric iron in his hand, and then presses it on the patient's chest. The shock can make people jump from the bed stand up.

It is generally manual defibrillation, has more features and functions than an AED, and is a larger device, often the size of a suitcase, and must be used by trained medical professionals.

The AED can be used by medical staff, by personnel who have received relevant first aid training, or even by ordinary people under the guidance of professionals.

The applicable scope and crowd of AED are undoubtedly wider.

The biggest difference between the two is that the AED automatically analyzes the patient's heart rhythm and makes a decision on whether to defibrillate.

However, the defibrillator must be decided and operated by a doctor based on the ECG indicators, which requires professional medical knowledge.

The defibrillator also has some other monitoring functions, such as: synchronized cardioversion, pacing, and even some plug-ins can measure blood pressure, blood oxygen saturation, end-tidal carbon dioxide, and so on.

Although the defibrillator is incomparable in price with hundreds of thousands or millions of medical equipment, its technical content is not low.

Don't think it's just a simple way to electrify a patient, but how and when to electrify is very important.

Otherwise, wouldn't it be simpler to just pull the two wires directly from the power outlet?

With just such a device, the market capacity has reached several billion!

Lu Tingfeng was still quite envious.

The monitoring function is the strength of Sanqing, so as long as these functions are added to make a medical defibrillator, it should not be a big problem.

Of course, he is just thinking about it now, and his main idea is to use it on the military medical all-in-one machine. It is necessary to make four samples of the new equipment as soon as possible, and then carry out the integrated design and make a medical box to complete a complete set of finished products.

When the engineer was making samples, he was not idle, but based on the actual combat exercises he experienced in the 120 Hospital, he made improvements and redesigns.

There are not many improvements in hardware, mainly using wear-resistant, durable, anti-vibration and anti-drop materials.

The software has to be adjusted according to some minor requirements of the military.

The main thing is to make it easy to understand, easy to use, and to simplify the program as much as possible to get it done within 3 steps.

In this aspect, he needs to personally check and try to meet the needs of customers.

Time flies, and because a group of new engineers are recruited, the manpower is very abundant, so the progress of the project is also fast.

On the basis of existing materials, after more than half a month, the prototypes of all four devices were all made.

*****

"Mr. Wei, the sample of the military medical all-in-one machine has been made, how do you see it?"

Lu Tingfeng put a suitcase in his hand on the desk and said vigorously.

The case is painted in camouflage patterns and is made of thick hard plastic throughout. It is about the size of a 14-inch hand luggage.

"Oh? Made it so soon?" Wei Kang was a little surprised.

"Isn't it that a large number of people have been recruited recently? They are all skilled workers who jumped over from other equipment factories. They can get started right away, so they made it very quickly."

With a click, Lu Tingfeng unscrewed the buckle and opened the suitcase.

Then gently rotate 180 degrees to show the whole interior in front of the boss.

Wei Kang's eyes lit up immediately, and he saw that the box was divided into three parts: upper, middle and lower, and all the equipment was sorted and placed neatly inside.

The upper part is the case cover, a thin layer, and a 10-inch screen hangs in the middle, which is the display screen of a portable color ultrasound. There are several pockets and hooks on the left and right, where some items such as hoses, gauze, and tourniquets can be placed.

The box is thicker and divided into upper and lower layers, which can be opened by mechanical racks, making the space more stretchable and convenient for taking equipment and medicines.

The middle layer is slightly shallow, with AEDs, simple automatic respirators, and portable monitors on the left and right sides.

The lower floor is relatively deep, and there are three pieces of equipment, a portable color ultrasound, a portable biochemical analyzer, a mini syringe pump, and some commonly used medicines.

Lu Tingfeng explained one by one: "Our equipment and medicines are arranged according to the order of first aid on the battlefield."

"The most important thing in battlefield treatment is to make an accurate judgment on the severity of the wounded as soon as possible."

"The most commonly used is the war trauma scoring method, which is to evaluate the three physiological indicators of the wounded's breathing rate, systolic blood pressure, and coma, as a reference for judging the severity of the injury and determining the order of treatment."

"Stopping the bleeding, restoring breathing and heartbeat are the most important principles of first aid. I put all the hemostatic and bandaging items on the upper floor, and the equipment on the middle floor can help the doctors and nurses give cardiopulmonary resuscitation, so that the wounded can resume breathing as soon as possible."

"As for other equipment and first-aid medicine, I put them on the lower floor. This is more in line with first-aid procedures."

"According to the first aid steps, the vital signs of the patient must be observed and stabilized first, and the first is breathing and heartbeat."

"The wounded can immediately wear a portable monitor to monitor body parameters, and at the same time use a portable defibrillator and a simple respirator for rescue. If the wounded's heartbeat and breathing have stopped, an AED can be used to automatically defibrillate and perform first aid with cardiopulmonary resuscitation.

"If the wounded cannot breathe, the trachea can be cut immediately, a hose can be inserted, and a respirator can be used for assisted breathing."

"The second step is to observe the blood pressure, bandage the wound and stop the bleeding. It is enough to spray the hemostatic agent on the superficial bleeding. If it is a relatively large blood vessel injury, it is necessary to use a tourniquet and a bandage to block the blood flow and stop the bleeding. .”

"The third step is generally to establish an intravenous channel and give rescue drugs such as epinephrine. In this case, a syringe pump will come in handy."

"Finally, if the injury is more complicated, such as being shot in the abdomen, poisoning, etc., it is necessary to dispatch a portable color ultrasound for diagnosis, and at the same time use a portable biochemical analyzer to do a detailed routine biochemical test, and use the results to understand the status of internal organs such as liver and gallbladder. .”

"Unfortunately, some equipment for fractures, such as splints or external fixation braces, can't be put in because of their relatively large volume, and additional equipment may be needed."

"In general, this first aid kit can be considered to meet all aspects of battlefield first aid needs, and it must be able to satisfy the military."

Wei Kang smiled gratifiedly and said, "Old Lu, you are really thoughtful and reliable in your work. I am very satisfied."

"Follow-up things, you can figure it out, take your time, don't worry."

"By the way, the AED is very effective in rescuing sudden death. If it is widely used, it can save many lives. How about it? After the review is passed, a batch of samples will be given to public places in Kunming City and some cities as charity. By the way, let’s popularize the common sense of first aid.”

He looked at Lu Tingfeng, and saw that the other party's eyes were bloodshot, and his expression showed a trace of fatigue, and he couldn't help but moved, "Look at you, your eyes are full of bloodshot eyes, hey, there's no need to fight so hard, don't mess with your body." collapsed."

"Why don't you rest for a while, the 120 side should not be in a hurry, you can wait until later."

Lu Tingfeng was so moved that his nose ached in an instant, and he quickly shook his head: "It's okay, Mr. Wei, I know my own physical condition well, and it will be fine if I rest for two days on the weekend."

"Besides," he raised his wrist, pointed at the smart watch, and said with a smile, "hasn't the watch called the police yet?"

As soon as the voice fell, the red light on the watch flashed crazily in an instant, and the piercing alarm immediately rang through the entire room.

"Warning! Warning! If you suspect myocardial infarction, please stop all actions immediately and go to the hospital for a professional ECG examination."

Lu Tingfeng's smile suddenly froze on his face.

Wei Kang suppressed his laughter and said with a straight face: "Don't be brave, I order you as a superior to go to the hospital immediately."

He looked at the watch on his wrist, and said in a very stern tone: "Ten minutes later, if I still see you in the Sanqing Garden, don't do this project!"
