How about Kangjuren oxygen generator?

First of all, it depends on whether you are interested in the brand, because the prices of different brands of oxygen generators are too different, and the better ones are basically imported.

The price is relatively high, like imported time-honored brands, but expensive. Slightly close

Like a fish jumping, a turtle jumping.

These brands can also make do.

At present, the most important thing to buy an oxygen generator is to look at its oxygen production. You can feel it yourself or read the instructions. The amount of oxygen required by different patients can be large or small. The normal oxygen generator is 3L-5L.

Larger 10L is also available.

Finally, look at the size and noise of oxygen generator. You can grasp this by yourself. It's best to keep your voice down, because patients with loud voices can't sleep.

Just hands ... exhausted.
