Hearing Aids 24. Dr. Segal asked the Minister of Health whether he will arrange, before the present output of Medresco hearing aids is doubled, to effect certain improvements in the existing type of this apparatus, especially with regard to lightness and ease of portability. Mr. Bevan Yes, Sir. Certain improvements have already been incorporated, but for the time being the size and weight will remain unchanged. Consideration is already being given to the reduction of size and weight of the aid and batteries. Dr. Segal Is my right hon. Friend aware that the best type of this hearing apparatus is equipped with miniature batteries? Could he make apparatus of this type available as an alternative under the National Health Scheme? Mr. Bevan No. Mr. Cobb Would my right hon. Friend please see that not too many changes are made for the time being so as to ensure that speed is not taken off the production of existing models? Mr. Bevan Changes are not being allowed to interfere with production. Research is going on so that in the next phase of production we shall be able to fit in the improvements. Colonel Stoddart-Scott As there are many better types of apparatus on the market than this one, would the Minister agree to allow people to purchase their own, and make a grant in aid? Mr. Bevan All the information I receive at the moment is that those who are using these aids are highly contented with them. I do not propose to give any more grants in aid in any direction.
