I bought these for my 100-year-old grandmother. They do reduce the amount of air she swallows and since they do remain full/filled she struggles less in taking the first sip. thank you very much for this!!
Straws with a discreet, built-in valve that makes drinking easier, sold in a pack of 10|||ARK's One-Way Straws make drinking easier for individuals with a weak suck, oral motor difficulties, and/or problems generating and maintaining suction. Each straw features a built-in valve that controls the direction of fluid one-way - fluid flows up into the straw, but does not empty back into the cup. With fluid remaining at the top of the straw, less air is ingested and less effort is required to drink. Users therefore tend to experience less coughing and choking while consuming more fluids. Because the valves are built-in, these straws provide both convenience for the caregiver and discretion for the user. They save time and labor for the caregiver/therapist while increasing independence, dignity, and hydration for the individual.
