History of Keidel Vacuum
This article doesn't tell how prevalent the keidel vacuum was used in the 1920's and 30's healthcare setting. It would be interesting to find this information out. Also, it would be nice to know when the keidel vacuum became obsolete. I think it was sometime after WWII (maybe 1948ish), but I am not sure. DestinyQx 07:59, 14 February 2007 (UTC)
