The problem with these early mist producing inhalers was that they required manpower to create the flow needed to create the mist. As with other industries, the ability to control electricity changed everything. Marketers soon started playing with the idea of creating an electric nebulizer.
The first one to enter the market was produced by Weil in Frankfort.
It was a compact unit, meaning it was a combination compressor and nebulizer. The comperssor created the electricity that created the flow to turn the solution of water and medicine to a mist.
According to "Hugh Smyth, in his book, "Controlled Pulmonary Drug Delivery," it was a "110-120 volt machine was supplied in UK by Riddle to nebulize bronchovydrin (papaverine and eumydrine)." (1, page 68)
Bronchovydrin also had adrenaline (epinephrine) and atropine in it. It was a solution used to provide quick relief of an asthma attack. I really had a hard time finding any other information on it, although it was used by lifelong asthmatic Harold Beck.
The electric nebulizer of the 1930s was epensive, so the physician may prefer to have the patient use a nebulizer where the flow is generated by hand power, like it was prior to the electric device. One option would be the Adrenaline Inhaler or the Devilbiss No. 40 Glass Nebulizer.
Considering the bulkiness and cost of this machine, it was common for a pharmacist to own one, and for patients in need to visit that pharmacist. (3)

ReplyDeleteI'm so excited right now, I just have to share my testimony on this Forum.. The feeling of being loved takes away so much burden from our shoulders. I had all this but I made a big mistake when I cheated on my wife with another woman and my wife left me for over 4 months after she found out.. I was lonely, sad and devastated. Luckily I was directed to a very powerful spell caster Dr Emu who helped me cast a spell of reconciliation on our Relationship and he brought back my wife and now she loves me far more than ever.. I'm so happy with life now. Thank you so much Dr Emu, kindly Contact Dr Emu Today and get any kind of help you want..
