Anti-bedsore air cushion bed jet or up and down which has its own characteristics! ~ Please give your opinions! ~

Hello, anti-bedsore air mattress spray is actually useless! You have a misunderstanding. Fluctuation and injection are actually one, which means that the bedsore prevention bed must fluctuate. Without fluctuation, bedsores can't be prevented at all! The main rules of fluctuation type are 1, 3,5. . A group of singular numbers, 2, 4 and 6. . . Even numbers are grouped together. When odd-numbered air cells protrude, even-numbered air cells are suppressed; When even air cells protrude, odd air cells are suppressed. Generally, it circulates once every 5-8 minutes (no matter what brand, it is basically this rule). As for the jet type, it's actually useless! I am a salesman of a factory, and I know a little about this. Generally, domestic manufacturers, no matter what they say, actually stick a needle into each air chamber regularly (some manufacturers are regular, some manufacturers are rough), so that when patients lie in bed, they usually spread a small mattress or stall on the air cushion, so that jet is basically useless! So personal advice, if you buy it, you can buy it fluctuating! These are just my personal suggestions! Thank you, if you need anything, you can leave me a message!
