Abstract:
An apparatus for establishing and maintaining a positive atmospheric pressure surgical field for use in reducing bleeding during surgical procedures comprising:(a) an enclosure constructed and arranged to define a chamber, the chamber sized to permit at least one member of a surgical team to be completely contained therein, the chamber having an opening to permit access to a surgical site of a patient from within the enclosure, the opening constructed and arranged to surround and form an air-tight seal about the surgical site of the patient thereby enclosing the surgical site within the chamber while excluding the rest of the patient from the chamber; and(b) a gas mechanism for delivering gas to said chamber to provide a positive gas pressure therewithin, said gas mechanism being capable of delivering sufficient gas volume to said chamber to cause said chamber to fill with said gas and establish an air pressure field within the enclosure which is greater than the air pressure outside the enclosure, the positive gas pressure providing the surgical site with an air pressure sufficient to inhibit bleeding and which is greater than that which the patient is exposed to outside the enclosure, said gas mechanism providing an exchange of air to maintain the concentration of gases as desired.
