Vacuum Bed
A vacuum bed is a device sometimes used in BDSM play. A person is placed in a latex envelope spanned by a frame and a suction pump or floor vacuum removes most of the air in the envelope. The frame can be either a simple rectangle of pierced PVC pipes, joined by PVC joints, or three-dimensional frames of various sizes, with a similar PVC construction. There are several ways that the vacuum bed can be designed to facilitate breathing. The most common is a tube running from outside of the vacuum bed into the person's mouth. A second option is a reinforced hole that is positioned so that the mouth protrudes. A third option is a reinforced gasket through which one forces the entire head. Incorporating a related fetish, some vacuum beds use a gas mask A gas mask is a mask used to protect the wearer from inhaling airborne pollutants and toxic gases. The mask forms a sealed cover over the nose and mouth, but may also cover the eyes and other vulnerable soft tissues of the f ...

A vacuum is a space devoid of matter. The word is derived from the Latin adjective ''vacuus'' for "vacant" or " void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a ''perfect'' vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is considerably lower than atmospheric pressure. The Latin term ''in vacuo'' is used to describe an object that is surrounded by a vacuum. The ''quality'' of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. ...
