What is the difference between a large hemodialysis machine and a small one? Is the small one not as good as the big one? Is it better to use a big machine or a small one?

The difference is not easy to say, just like whether a Dongfanghong tractor or a Rolls Royce is better. Mainly depends on your use and positioning, because the dialysis machine is used very often, the choice of reliable and safe performance of the machine is still very necessary. It has little to do with the size. There is also whether the design of the machine itself is reasonable. For example, so-and-so machine water and circuit together, it is easy to have problems, you repair the cost of more than earned, rely on what to make money ah.
