People with asthma and other respiratory problems should use an inhaler. Inhalers release medicine into the nostrils. Breathing freely will do that. There is no guarantee that the exact dose of medicine will be released each time they are used. Regular inhalers have a slight fluctuation in the dose of medicine released each time they are filled. The Digi haler releases the drug in a precisely defined dose without any such hassle. It works via Bluetooth connectivity. This digital inhaler has been developed by ‘Teva’ company of Britain under the brand name ‘Go Resp Digi haler’. The Digi haler is available in two models. One model emits 55/14 micrograms while the second model emits 118/14 micrograms. The price of this Digi haler is 3099 dollars (Rs.32,709/-).
