What are the common medical equipment used by the elderly? Which brand is more recommended ah

It seems that you are more concerned about the elderly as I am, I'll say it, oxygen concentrator, blood pressure monitor, therapeutic instrument, respirator, hearing aids, oximeter, nasal aspirator, phlegm inhaler and so on are very likely to be used by the elderly, to recommend a very good brand, the medical pulse, which is specializing in this area, the quality is very good, I gave the family to the elderly to buy this brand of blood pressure monitors, hearing aids and respiratory machines, are very good to use.
