Cardiopulmonary drainage collector with blood transfer adapter

Claim 2

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.

Claim 3

A drainage collector according to claim 1, wherein said means of controlling suction comprising an adjustable controller combined with a visual indicator to indicate the level of applied suction in direct response to the adjustable controller.

Claim 4

A drainage collector according to claim 1 including a high negative suction relief valve.

Claim 5

A drainage collector according to claim 3 wherein said positive pressure relief valve and said high negative suction relief valve are operatively associated with said second opening exit.

Claim 6

A drainage collector according to claim 1, said chamber comprising separate first and second chamber sections disposed side by side and interconnected by an overflow passage extending between the upper portions of said chamber sections, said liquid seal disposed in said first chamber section and said downstream terminal portion of said chamber being the upper portion of said second chamber section.

Claim 7

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.

Claim 8

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.

Claim 9

A drainage collector according to claim 6 wherein a high negative suction relief valve is provided in said control module.

Claim 10

A drainage collector according to claim 6 wherein the opening and patient tube juncture are connected by a removable screw coupling.

Claim 11

A drainage collector according to claim 6 wherein the transfer means comprises a puncturable seal.

Claim 12

A drainage collector according to claim 6 wherein the transfer means comprises a removable seal cap.

Claim 13

A drainage collector according to claim 6 wherein the collector comprises at least first and second chamber sections.

Claim 14

A drainage collector according to claim 11 with a first chamber section housing the liquid seal and a second overflow chamber section connected to the first chamber section.

Claim 15

A drainage collector according to claim 6 wherein the collector is a blow molded rigid container and the suction control module is a separate unit attached to the exit port of the blow molded container.

Claim 16

A drainage collector according to claim 6 wherein the suction control module further houses said positive pressure relief valve and a high negative suction relief valve.

Claim 17

A drainage collector according to claim 6 wherein means are provided on the collector for hanging the collector at bedside.

Claim 18

A drainage collector according to claim 6, said chamber comprising separate first and second chamber sections disposed side by side and interconnected by an overflow passage extending between the upper portions of said chamber sections, said liquid seal disposed in said first chamber section and said control module disposed above the upper portion of said section chamber section.
