§ 8. Mr. Errollasked the Minister of Health why, in view of the fact that 80 per cent. of deaf aids now manufactued are one-piece aids, he has decided on a two-piece aid for free supply to the deaf under the National Health Service.
§ Mr. BevanThe decision has been taken owing to the disproportionate cost involved in using the miniature batteries required for one-piece aids.
§ Mr. ErrollIn view of the fact that the Government aid is being manufactured on a mass production basis surely it is possible to make a one-piece aid on a cheaper basis?
§ Mr. LipsonCan the Minister say when these will be available?
§ Mr. BevanThat is another question. I have said that they will be available when the National Health Service starts on 5th July next year.
§ 9. Mr. Errollasked the Minister of Health what scales of spares and replacements have been allowed for to service the two-piece deaf aid now being manufactured for free supply to the deaf.
§ Mr. BevanThe general basis adopted has been an annual replacement rate of 25 per cent., with a higher rate for valves owing to their shorter life.
§ Mr. ErrollCan the Minister say why a very much higher rate of replacement was decided upon in the case of his unit than is customary in normal commercial practice?
§ Mr. BevanI understood that British valves are being used in order to save dollars and we could not be sure what the experience with them will turn out to be.
§ Mr. ErrollHas not the instrument been properly tested?
