The Bruck Inhaler is a modification of the Clover Inhaler, designed by Lambert Bruck. Bruck added a glass dome which enabled the level of ether to be monitored during administration. This was a revolutionary change as it removed guess work from the process.The inhaler is oval shaped with two halves. One half should be made of glass [missing] to allow observation of the ether level. A vertical cross tube, 22mm in diameter passes between the face-piece and the bag [broken]. There is a stopcock for admission of oxygen or nitrous oxide opposite the bag attachment. There is a central tube, 28mm in diameter, with controllable ports on either side.The Bruck Inhaler is a modification of the Clover Inhaler, designed by Ludwig Bruck.
