Abstract
A suction bottle for aspirating would secretions containing a small quantity of a pressure-adjusting liquid selected so that its vapor pressure conforms to a desired vacuum level. The vacuum level is maintained until the suction bottle is almost completely filled. If the liquid dissolves in the aspirated secretions, the vacuum level will decrease. The vacuum level can be varied by changing the temperature. The bottled can be made with thinner walls than bottles used heretofore because the risk of deformation during sterilizing is reduced as the inside pressure rises with the increase in temperature. For the purpose of connecting a suction bottle with a connecting tube joined with a wound draining system, provision is made for a connection system embodied as a suction controlling device.
