I heard that Tesla built a ventilator to support the front line? look carefully/closely ...

In March this year, Musk, who was overwhelmed by the COVID-19 epidemic, got an accurate hint from Mayor new york on Twitter. The mayor said that he is the owner of Tesla and likes this company very much, so Tesla should produce ventilators ... It is also quite awesome to think about this logic carefully. ...

What can Musk say? Yes, of course. And claimed that Tesla has an air conditioning system, Space? x？ There is a life support system. Since Dyson can build a ventilator by vacuum cleaner technology, it seems that I can build a ventilator by air conditioning system. It's all about breathing

Of course, compared with Ford and GM being named by the president, Tesla is only named by the mayor, and his burden seems to be lighter.

Later, the people who ate melons found that Musk imported a batch of ventilators from China. ...

Well, people who eat melons at home laughed at Musk's boasting. In the end, China had the final say. When evil capitalism failed at a critical moment, Tesla released a video to prove that he was using Model? 3? The parts of the ventilator are developed!

On the whiteboard shown in the video, the system structure diagram of this ventilator is drawn, in which orange is Tesla's auto parts, blue is medical parts, and gray is other parts. At least from this picture, the usage rate of Tesla and ventilator parts is quite high.

From the video, we can see that the mixer, main engine, heater, monitor and other parts of this ventilator use Tesla cars.

From a video, Tesla's ventilator seems to be passable.

At this time, a famous person will be on fire: "Tesla can be a ventilator, why don't China car companies make it?" "China car companies will also make masks, which have no technical content, and high-tech ones will not ..."

People who say such things are really ... well, let's talk briefly. Why is it so difficult for car companies to build ventilators today?

■? It's really difficult to build a ventilator!

This is a schematic diagram of the ventilator in Baidu Encyclopedia. It looks simple, but it's not!

Look at the hardware first. According to the video of Weibo @ explaining X-PLAN, the ventilator needs the following hardware:

Microcomputer, high-precision pressure sensor, air mixer, electromagnetic valve, compressor, medical pressure detector, etc.

Even if these hardware suppliers can solve it, even in the car, you should know that the most critical components of the ventilator are the following two.

Let's look at the interpretation of professionals. According to the legend of Zhihu netizens, the legal representative of the medical device company @ Ventilator Craftsman, the core of the ventilator is the motor and the underlying algorithm, and these two things happen to be the housekeeping skills of medical device manufacturers, both of which are closed; Similar to Tesla's own AP and FSD, it is difficult for laymen to get it.

Then there is the algorithm. I believe Tesla knows clearly that its AP and FSD are powerful in complex algorithms and have the ability to iterate constantly, so that it can achieve a unique NOA.

So is the ventilator. How to switch the pressure? How to establish an accurate flow control system? How to improve and reduce the pressure according to the degree of obstruction and airflow of patients?

In addition, professional manufacturers with many years of experience in producing medical devices can also attack COVID-19 accurately. For example, Yuyue, a domestic ventilator brand, has rushed to Hubei to help more than 7,000 non-invasive ventilators, and made many optimizations for the epidemic situation, such as making ventilators more targeted at COVID-19 patients, better ensuring the stability of equipment under high pressure, and optimizing algorithms based on a large number of epidemic clinical data, which are not something that car companies can learn in a short time.

Yu Yue said that even if they have increased the production capacity several times for the epidemic, it may take as long as 40 days for professional medical equipment manufacturers to produce a ventilator.

To sum up, the production of ventilators is a matter of great pressure on hardware, software, technology and time, which is different from the production of masks.

■? American hospitals received Tesla's ventilator?

Some overseas netizens took photos, and the American hospital received a ventilator with Tesla logo, and it also said, "Thank you? What about you? Tesla's slogan expressed gratitude.

Isn't this amazing? The front foot just released the video of self-developed ventilator on YouTube, and the back foot ventilator was sent to the front-line medical staff?

Just when the special blow began to climax, witty netizens found that this ventilator was Tyco PB840…… ... ...

I also found Tyco's PB840 on the Internet, and it's really similar by comparison.

Moreover, it was previously reported that Tesla will cooperate with medical device manufacturers such as Medtronic to produce ventilators.

However, as netizens said, Tesla definitely didn't just assemble the ventilator and label it. We should also systematically study the technical standards of production and assembly before sending the "Tesla" ventilator to the front line. After all, life is a matter of life, so we can't be careless.

■? Do you really use China car companies to produce ventilators?

Think about when domestic car companies switched to producing masks. At that time, when the epidemic broke out, it was difficult for mask companies to return to work, and citizens could not buy masks at all. Now the domestic epidemic has stabilized, Hubei is gradually returning to work, and Wuhan is about to be unsealed; Domestic medical equipment manufacturers can basically meet domestic demand, and even receive foreign orders or provide humanitarian assistance. Therefore, there is no need for car companies to switch to areas with high learning costs and high industry barriers that they are not good at at at this time. Besides, their sales are not good these months, so let them produce a few cars first.

In fact, whether it is Tesla, Ford or GM in the United States; BYD, Wuling and GAC in China, as the "lifeblood of the national economy", should be on their heads when the country needs them. From ancient times to the present, the phrase "Wuling must build what people need" is definitely not a slogan. Car companies all over the world are trying their best to contribute to their motherland. This attitude and spirit is worth learning from every industry, every company and even everyone.
