Rettungsgerät für ertrunkene Schwimmer
In 1926, Dräger introduced the Bade-tauchretter 1926 rescue device. The device is the successor to the very early introduced device Baderetter 1913 of which, unfortunately, no information can be found. It was supposedly discussed in Drager Hefte 12 of June 1913, but unfortunately I have not been able to obtain the document. After 1913 followed the Badetauchretter 1915 which was very similar to the D2 tauchretter but executed without swim bladder. The 1926 badetauchretter was equipped with steel sandals and a neck belt that had to weigh the rescuer down to descend. In the same period, an early Gegenlung was also introduced, distinguished from the badetauchretter by the implementation of the contralong. With the gegenlung, the lung is worn around the neck (as with all later tauchretters) with the bade-tauchretter, the contralung is positioned on the back. The 1913-1915 lifesavers were advised by Dräger to be used up to 30 metres deep, noting if diving that deep required the air not to be flushed out of the contralung. Shallow dives allowed diving on pure oxygen. The unit was therefore offered in a semi-closed version. The Bade-tauchretter was recommended for diving depths of up to 15 metres. A constant flow of oxygen of 1.25 l/min was injected.
Therebreathersite was founded by Jan Willem Bech in 1999. After a diving career of many years, he decided to start technical diving in 1999. He immediately noticed that at that time there was almost no website that contained the history of closed breathing systems. The start for the website led to a huge collection that offered about 1,300 pages of information until 2019. In 2019, a fresh start was made with the website now freely available online for everyone. Therebreathersite is a source of information for divers, researchers, technicians and students. I hope you enjoy browsing the content!
