Abstract
A drainage collector capable of draining and collecting fluid especially blood from the cardiopulmonary system during and after a surgical operation. A drainage sump is provided with a liquid seal to prevent outside air from entering the cardiopulmonary space. A dry suction control means with a built in positive pressure relief valve and high negative relief valve is incorporated within the drainage collector. Further, a blood transfer adapter is provided such that collected blood can be readily transferred to either a blood bag or to an autotransfusion device for recirculation of processed blood back into the patient.
Claims16
A drainage collector capable of draining and collecting body fluids from a patient especially blood from a surgical site, said collector comprising a closed collection chamber having first and second openings, said first opening adapted for attachment to a drainage tube from the surgical site, a sump provided within a lower portion of the chamber and adapted for receipt of said drainage tube, said sump providing a liquid seal to prevent reflux of air from entering said patient tube yet permitting air from the patient tube to escape into said chamber and wherein body fluids directed into said sump upwardly rise towards a downstream terminal portion of said chamber, an air passageway in the downstream terminal portion of said chamber permitting the escape of collected gases through said second opening, said second opening forming an exit from the chamber in air communication with said air passageway, dry means operatively associated with said exit for controlling suction applied to said chamber via said second opening, said chamber including a positive pressure relief valve, and said chamber further incorporating transfer means wherein collected body fluid can be aseptically transferred or emptied therefrom.
A drainage collector capable of draining and collecting body fluids from a patient especially blood from a surgical site, said collector comprising a closed collection chamber having first and second openings, said first opening in the upper portion thereof, a drainage tube adapted for connection to said first opening, said drainage tube further extending inside said chamber, the juncture between said drainage tube, said first opening in the collector, and the interior extending drainage tube forming an air tight seal, said interior extending drainage tube in fluid communication with the lower portion of the collector, means for adding fluid to the lower portion of said chamber to form a liquid seal between the interior drainage tube and the lower portion of the chamber, an upper portion of the collector acting as a passageway for escaped air from the interior drainage tube, said upper portion including said second opening in turn forming a chamber exit port adapted for connection to a suction control module for selectively controlling the level of applied suction to the collector, said suction control module comprising a variable dry controller in combination with a visual indicator to show the level of suction being applied in response to the variable action of the controller, an exit port on said suction module for connection to an external suction source, said control module including a positive pressure relief value, said collector further comprising a transfer means in the lower portion of said chamber wherein collected body fluid can be aseptically transferred or emptied therefrom, said transfer means positioned above the level of the liquid seal such that body fluids from the collector may be continuously drained from the collector down to the level of the liquid seal.
