Thank you so much!
I have contacted BMPI by email and now I'm waiting for their reply. Also I am in charge of a export&import company in Shanghai, now I am going to do business with BMPI about this kind of products.
Again thank you for your kingly comments.
What you are looking for is VERY-VERY easy. Its called a laryngectomy tube. Your fathers insurance company should be able to locate a plastic or latex tube to fit him comfortably. Other wise, the internet is riddled with companies that offer them. However, a professional should be available to recommend the appropriate size and length. BE sure to see only a speacilist in this field like a Respiratory Therapist or an ENT specialist. PA's, NP, and nurses are usually not specially trained airway management and rarely covers their scope of practice.
Singer Inc is a popular company here in Boston. They are supplied by Boston Medical. They are amoungst the top in the country.
