I recently purchased an H&H Inhalator, which was used at the East End Hose Co in Derby, CT from the late 1930s until approx. the 1970s. There are hydrotesting dates on the unique "Carbogen" cylinders (MSA's specified mix of 93% oxygen, 7& carbon dioxide. https://en.wikipedia.org/wiki/Carbogen) from the late 1930s and the latest in the mid-1950s. At some point, the case was repainted - many of these cases seem to have aged poorly.

The H&H Inhalator has no positive pressure mechanism - so it must be used with spontaneously breathing patients or with Back Pressure/Arm Lift types of artificial respiration. It was introduced in 1922, and sold at least into the 1950s. The CO2/O2 mix was designed to hyperoxygenate while also stimulating the respiratory drive of the patient to breathe. Use of this device was covered in the early Ohio Trade/Industrial Rescue Squad Manuals as well as the various iterations of thel "First Aid and Resuscitation" manuals put out in cooperation with the American College of Surgeons by C.B. Young in Corpus Christi, TX during the mid-1950s. The 1970 edition of his book does not discuss the unit.

One cool item was that a sales/news photo of the unit in action was included with the sale of my inhalator. It's damaged, but surprisingly sharp/clear in the undamaged areas. I have scanned it in for your viewing pleasure.

Close-ups so you can read the H&H instructions. Excuse the water damage.
