Vacuum Bell (medicine)
The vacuum bell is a medical device used in the treatment of pectus excavatum, one of the most common chest wall defects. The vacuum bell was invented by German engineer Eckart Klobe in order to treat the cosmetic problems associated with the condition, as symptomatic problems caused by pectus excavatum are usually more severe and may require surgery. Currently, there are two leading versions of the vacuum bell (COsta an Klobe) are available, in a range of different sizes in order to allow for the treatment of a range of patients. The device works by establishing a vacuum, of up to 15% below atmospheric pressure, above the patients chest in order to draw the sternum out into a more normal position . Whilst the immediate effects of the device are only temporary as the sternum will revert to its original position after usage, the continued usage of the device is believed to have a permanent impact on the position of the breastbone. Many patients have reported an improved appearance to the sternum after 2–3 years of regular usage.

Famous quotes containing the words vacuum and/or bell:
“No, it wasn’t an accident, I didn’t say that. It was carefully planned, down to the tiniest mechanical and emotional detail. But it was a mistake. It was a beaut. In the end, somehow granted the time for examination, we shall find that our so-called civilization was gloriously destroyed by a handful of vacuum tubes and transistors. Probably faulty.”
—John Paxton (1911–1985)
“The one who should remove the bell is the one who hung it up.”
—Chinese proverb.
