Chest tube drainage system
First Claim
1. A suction device comprising:
- a pump operatively connected to a power supply;
a desiccant material in a desiccant chamber fluidly connected to the pump;
a tube fluidly connected to the desiccant chamber through a tube connection;
a terminus having a first lumen and a second lumen fluidly connected to the tube on an end opposite the tube connection, the first lumen and the second lumen sharing a same wall; and
a plurality of fenestrations positioned through the first lumen and the second lumen to allow air and liquid to flow between the first lumen and the second lumen;
wherein the first lumen is larger than the second lumen to permit a higher flow rate in the first lumen than in the second lumen.

Abstract
A system for draining the chest cavity of a patient subjected to a traumatic chest injury and/or to surgery within the chest. The system includes a small, portable suction device and a chest tube with an improved terminal structure. A number of embodiments of the suction device are disclosed; the first (with two variations) a small, completely disposable, bottle-shaped assembly comprising a motor/pump section, a power section, and a desiccant filled chamber, the second (also with two variations) a small box shaped assembly with a disposable desiccant pouch and a power supply that mounts to a battery charger positioned on an IV pole. A number of chest tube terminus structures are disclosed, including multi-lumen structures having high-airflow and low-airflow lumens as well as “dead” and “live” lumens. Fenestrations are variously positioned between and through the lumens in order to collect coagulated components of the extracted fluids and prevent them from clogging the primary flow tube and restricting or preventing continuous airflow.

18. A suction device comprising:
-
a pump operatively connected to a power supply; a desiccant material in a desiccant chamber fluidly connected to the pump; a tube fluidly connected to the desiccant chamber through a tube connection; and a terminus having a first lumen and a second lumen fluidly connected to the tube on an end opposite the tube connection, the first lumen and the second lumen sharing a same wall; wherein said first and second lumens comprise a central suction tube and a dead space in an interior of said terminus, wherein said central suction tube has fenestrations between said central suction tube and said dead space that allow communication between said central suction tube and said dead space. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
