The following note was attached at least: According to my ENT, this type of ear syringes are not the last word, and he advises explicitly of their use from. While rinsing the ears impurities and in this way bacteria can settle in such a syringe, and there is also inside the balloon due to the very small opening, the risk of mold growth. It is better, because we want to be active in ears symptoms themselves, instead at the pharmacy much cheaper a syringe made of plastic (Injekt Solo - 1 - 2 part disposable syringe (20 ml)) to procure. Those who consider it appropriate, may also be a specially designated Health Enterprises use 9555 Acu-Life earwax removal syringe. If deposits form in such transparent syringes inside the piston, so that's easy to spot compared to a bulb syringe. This type syringes should then no longer try to clean when occurring impurities, but dispose of the same.
