The efficacy of the mixture was controversial. Its use was not longer accepted after 1931 though it was not until 1945 that Somnoform was reported to be an “irrational” mixture.” (ref.2) In practice a capsule of Somnoform was cracked into a higher chamber and with the aid of a breaking device in a lower changer the liquid dropped into a large rubber bag that hung off the base of the inhaler system. The inhaler was placed over the nose a mouth cover was used to prevent respiration through the mouth; intake of air was controlled by a valve close to the mask. | Medical Technology | Instruments | Surgical | Medical Technology | Chemicals & medications | Anaesthesia | metal | 18.5 | 8.7 | 5.3 | http://source.techno-science.ca/artifacts-artefacts/images/2014.0037.001.aa.cs.png | http://source.techno-science.ca/artifacts-artefacts/images/2014.0037.001.aa.cs.thumb.png |
