A clinical staff member slowly approached Su Yinghao's left hand with a burning alcohol lamp.

When the alcohol lamp was only 20cm apart from Su Yinghao's left hand, Su Yinghao said excitedly: "You can feel the feeling of being hot, and it will hurt if you get closer!"

"No, the bionic prosthesis has no pain, you will just feel hotter and hotter, and then when it reaches the critical point, the perception chip in the prosthesis explodes."

Even though he said that, the clinical staff stopped their hands and did not let the alcohol lamp continue to approach Su Yinghao.

Chang Cheng looked at the magical scene in front of him and asked in confusion: "What's going on? If you don't have pain, you shouldn't feel the heat? After all, burning sensation is also a kind of pain!"

The staff member shook his head and explained: "The perception of hot and cold is partly tactile and partly pain."

"Only when the temperature is too low or too high, exceeds the safety value and destroys human cell tissue, it will change from touch to pain."

"For example, when you put your hands in a basin of 3℃ of ice water, you will feel cold, but this cold is not so cold that it destroys cell tissue, and you will still feel cold, right?"

"The same goes for heat, and when you put your hands next to the stove, you won't feel the warmth."

"Only when the temperature is too high, such as putting your hands in boiling water, will there be a burning and tingling sensation. This is the pain that leads."

"Under normal circumstances, if you suddenly put your hand in hot water above 42 degrees Celsius, we will feel the hotness. It will be very hot over 50 degrees Celsius. If it is above 60 degrees Celsius, the protein in the tissue will start to deteriorate, and in this case it will be extremely hot and even unbearable."

"But because our bionic prosthesis does not load the pain template, patients will not feel the heat when wearing it. When the temperature exceeds 42 degrees Celsius, they can only feel the temperature of 42 degrees Celsius. Even if the water temperature reaches 60 or 70 degrees at this time, they cannot feel it."

"Similarly, when the room temperature is below -20 degrees Celsius, patients can no longer feel the colder feeling, and the lowest temperature can only feel -20 degrees Celsius."

"But it is worth mentioning that our bionic prosthesis also has IPX-7 waterproofing. Usually, water will not cause short circuit when splashing on the arm. Even if you take a bath, as long as you don't completely soak your arms in water for more than half an hour, there will be no water in it."

"If you shower normally, you can achieve a waterproof effect of 40-50 minutes. Generally, ordinary people will not take a shower for more than 40 minutes, right?"

"When you are in hot springs or bathtubs, your arms are usually not kept in water. As long as you don't soak for a long time, the waterproof performance is enough for daily use."

"Unless patients encounter extreme situations like falling into the water in the ocean, our bionic prosthetics will work normally."

After explaining the reason for temperature perception, the staff did not forget to add: "The working temperature of our bionic prosthesis is at the industrial level and can work between -40 degrees Celsius and 85 degrees Celsius."

"As long as this bionic prosthesis is not placed in a temperature below -40 degrees Celsius and above 85 degrees Celsius, it will not stop working. However, once this limit is exceeded, the electronic components in the prosthesis may be damaged and cannot be repaired. You can only replace it with a new one..."

Chang Cheng nodded with an enlightened look on his face, but he didn't think this limitation was too harsh. Industrial-grade waterproofing and industrial-grade working temperature were enough to cope with daily use.

If a patient really encounters a situation that exceeds these two restrictions, it is no longer important whether the bionic prosthesis will be broken. What he should worry about is whether he can survive!

"Okay, the hard test is almost over, and the results are still very pleasant. In actual use of bionic prosthetics, the feedback from all aspects is very good, and there are no major problems. There are some action commands that seem to be not accurately identified, and some sensors do not perform as they should."

"We will feedback these problems to the company headquarters afterwards and then modify them and resolve them, but Xiao Su's task is not over yet."

The staff in charge of clinical testing closed their own document record book and said to Su Yinghao with a smile on his face: "Next, we will accompany you for a week of daily activities of bionic prosthetic limbs to record and test the daily activities of bionic prosthetic limbs. The products should be used more to discover the shortcomings in daily use and design defects."

"Thank you Xiao Su for your hard work."

Su Yinghao quickly shook his head, held his left hand excitedly, and said in panic: "No, it's not hard at all. If it weren't for Ruikang Medical, I would never have had such a perfect left hand. I would definitely cooperate with your work. You can mention anything you need."

The staff waved their hands and said kindly: "We are helping each other, so we don't have to be so kind. When the entire test is over, this first-generation bionic prosthetic limb will be given to you as a souvenir. After our official version of the product is launched, we will also give you a copy as a reward for this clinical test."

Since the beginning of the test, Su Yinghao's mother has been standing quietly in the corner of the reconstruction room, covering her mouth and watching her son perform a series of hand function tests. When the staff said that the formal product would be given to Su Yinghao, she hurriedly walked forward at a loss and thanked:

"Thank you, thank you very much. I really don't know what method should be used to repay you for this kindness."

"This bionic prosthetic limb is absolutely not cheap. It may cost hundreds of thousands or even millions of dollars to afford it. With our family conditions, it is difficult to get such a sum of money for a while. If you are willing to give us a formal product, I really can't think of how to repay this kind of kindness."

Su Yinghao's mother was about to kneel down as she spoke, which scared the staff of the clinical team and quickly helped Su Yinghao's mother up.

"Mom Su Yinghao, we ordered Mr. Chen to give Xiao Su products. We just told you to tell us. We really can't bear to give us this great gift."

"And even Mr. Chen is unwilling to accept your gift. Xiao Su cooperates with our test work very much. He is so young and has a long road ahead. He should not be discussed or discriminated against because of his disability. We should do this."

"We should give it to you and give it back. This is what you should do. You don't have to have too much burden in your heart."

Su Yinghao's mother covered her mouth and cried bitterly, and nodded with sobs. She knew that what the staff said were excuses to comfort her. She had met a good person!
