Vol 6 Chapter 3359: How to replace internal consumables

【Revision】

"Have the artificial kidneys and artificial lungs been developed here?" Brother Ma decisively changed the subject and asked, pointing to the smart bionic artificial kidneys and smart bionic artificial lungs displayed on the booths on both sides.

Wu Hao nodded slightly when he heard this and said: "These two products have also been developed and are currently in the clinical trial stage.

In fact, compared to intelligent bionic artificial livers, the technologies of these two products are more mature. In fact, they all already have extracorporeal circulation system products. What we do is to reduce these huge extracorporeal circulation equipment to a size that can be installed in patients, thereby helping patients overcome the disease and return to normal life. "

"I'm afraid this won't be successful by simply shrinking it." Mr. Zhang couldn't help but said after hearing this.

Of course, Wu Hao nodded and said: "Any breakthrough in medical technology is never easy, especially when it involves such a complex and sophisticated system of the human body.

This is indeed not a matter of simply shrinking the device. The first thing we face is to maintain the stability and functional integrity of the device while ensuring that it is small enough to be implanted in the patient's body. "

Wu Hao glanced at everyone, and then explained: "Whether it is an artificial lung or a hemodialysis equipment that replaces kidney function, they are all very large.

How to reduce such a huge device to a small size and then implant it into the patient's body to replace the original organ is the core problem we face.

In order to overcome this problem, your project team went through countless tests and improvements before finding a breakthrough and overcoming the problem in one fell swoop.

After hearing Wu Hao's answer, everyone nodded. We are full of confidence in Wu Hao's team and full of expectations for the future of intelligent bionic organs.

Everyone present heard this and frowned, obviously realizing the indirectness of the question. Everyone pondered for a moment, then looked at Wu Hao, waiting for my explanation.

I paused for a moment, glanced at the smart bionic artificial kidneys and artificial lungs under the booth, and continued: "Of course, just reducing the size of the equipment is enough.

You have to find a way to replace the filtration systems of those organs without harming or harming the patient.

The filtration system of the smart bionic artificial lung needs to be replaced every eight to seven years, while the filter material of the smart bionic artificial kidney has a shorter service life, about two to eight years. "

But the two artificial organs are implanted in the patient's body, and how to replace them becomes a small problem. "

It must be just a single component. Is there any problem in miniaturizing a single device? But it must be miniaturizing the entire system, which is only a little bit difficult.

Looking at the people who were full of curiosity, Qin He spoke with a bit of pride and continued with a smile: "Using the latest nanotechnology and biological materials to miniaturize each component of the equipment while ensuring their durability. Functionality is affected.

If so, its filtering effect may be slightly reduced.

Rather than going deep into the patient's body through the trachea and urinary tube, it can reach directly into the intelligent bionic artificial liver and intelligent bionic artificial kidney implanted in the patient's body to facilitate the replacement of filter materials.

Seeing this, Qin He said with a purple smile: "How to replace the filtration systems of those two organs is indeed a difficult problem.

In this regard, Wu Hao said with a smile: “Smart bionic artificial liver and smart bionic artificial kidney use the same type of filter material, so their service life is also the same.

At present, your mainstream direction is to simplify the process of replacing the filter system through minimally invasive surgery, thereby reducing the harm to the patient.

And that also creates a problem. Whether it is the air filter element or filter of the air conditioner or the filter element of the water purifier, they are all consumables and need to be cleaned and replaced regularly.

Basically speaking, in addition to the need to replace the filter material every few years, in daily life, those patients are basically about seven times the same as abnormal people. You think that price should be acceptable to both the patients and their families.

That's also a huge challenge, and your team has put in a huge effort in that regard. "

That question was also the focus of everyone's attention. After hearing Mr. Li's question, everyone also looked at Wu Hao.

The same goes for smart bionic artificial livers and smart bionic artificial kidneys. They do not have their own filtration systems and need to be replaced regularly.

Of course, there are still many problems with that technology, such as how to reduce the size of the filter material, how to replace the filter material, etc.

After answering the question, Wu Hao then said: "Of course, whether it is replaced every eight to seven years or every two to eight years, it may be perfect enough for those patients, and they may suffer some pain, but in any case It is much weaker than losing your life, relying on expensive ecmo to maintain your life, or having to go to dialysis every few days to maintain your life.

But in your opinion, it is still perfect enough. You hope to be able to develop lossy replacement filter materials, or even artificial organs with replacement filter materials, so as to cure those patients once and for all, so that we can recover as before and live like abnormal people. "

The function of the lungs is to carry out gas exchange outside the blood, exhale waste gases such as carbon heptaoxide, and absorb oxygen.

Speaking of that, Qin He glanced at everyone, and then sighed and said: "Of course, there is no problem. It doesn't matter whether it is a smart bionic artificial lung or a smart bionic artificial kidney. They are different from the artificial ones behind. The liver, artificial heart, and even electronic prosthetic eyes are the same, because those two organs are the blood circulation organs of the human body.

You also need to solve the compatibility issue of the devices to ensure that they can perfectly integrate with human tissue and avoid rejection.

It cannot be said that every detail of it embodies the hard work and wisdom of your team. "

It is complicated to replace the filter material of the internal filtration system of the smart bionic artificial liver and smart bionic artificial kidney through minimally invasive surgery, thereby reducing the harm to the patient. "

I glanced at everyone and saw the look of surprise on our faces, and then continued: "Besides this, you are also exploring a new technology, which is not a lossy filter material replacement technology.

But you suspect that through continuous efforts and exploration, you will be able to find an ineffective replacement method so that patients do not need to worry about replacing the filter system when using those smart bionic organs. "

The kidneys are used to filter and metabolize waste from the blood.

The air filter element of the air conditioner and the water purification filter of your tap water have basically similar functions.

"Mr. Wu, how long can the filter materials of those two artificial organs be used? If they are replaced too frequently, it will be too happy for the patient, and it will only increase the cost. After hearing this, Mr. Li asked Wu Hao immediately.

Because they are implanted in the patient's body, they can be replaced directly like traditional replacement methods.
