APPAREIL OXYGENOTHERAPY PORTABLE - DR. LESIEUR PARIS À ECQUEVILLY

Appareil Oxygenotherapy Portable - Dr. Lesieur paris. Manufactured by J. Mandet, Paris for the French inventor Dr. Lesieur, Paris was undoubtedly ahead of its time. As a progressive physician, active in oxygen therapy, he was able to have to build portable instruments with a pressure gauge. Patients with breathing problems we're able to independently provide themselves with medicinal oxygen. The machine has not been checked for functionality. The pressure cylinder is connected and via mandet regulator and pressure gauge controllable outgoing pressure (IN KILOGRAMMES) readable for registration. If this set was also used for e.g. inhaling other medicinal gases is not known. Presumably circa 1910. Dimension: 24x18x10 cm Weight: 3600 grams
