Abstract
A drainage system, the drainage system comprising a container having an interior and a mouth, the mouth comprising an outer surface and an opening, a frangible seal covering the opening, a cap secured to the mouth and in fluid communication with a drainage line, the cap having an inner surface configured to engage with the outer surface of the mouth, an O-ring located at least partially between the outer surface of the mouth and the inner surface of the cap and configured to form a fluid seal between a space defined by the cap and the space located externally of the drainage system, and a retaining ring circumferentially engaging the cap.
Claims20
A drainage system comprising:
- a container having an interior, a mouth comprising an outer surface, an opening and a shoulder where the container widens to an increased internal volume;
- a frangible seal covering the opening, the frangible seal having a surface perpendicular to the outer surface of the mouth;
- a cap secured to the mouth and in fluid communication with a drainage line, the cap comprising a body having an inner surface configured to engage with the outer surface of the mouth and a sleeve that is monolithic with the body and that extends away from the mouth;
- an O-ring located around the mouth and between the outer surface of the mouth and the inner surface of the cap such that the O-ring forms a fluid seal between a space defined by the cap and environment surrounding the drainage system;
- and
- a retaining ring formed separately from the cap that is configured to be radially aligned with the O-ring and coaxial with the O-ring to provide a constricting force on the O-ring;
- wherein the body of the cap comprises a stop that is monolithic with the body, the stop extending outward from the mouth and along the shoulder, the retaining ring resting on the stop when the retaining ring is radially aligned with the O-ring.
A drainage system, the drainage system comprising:
- a container having a mouth with a first surface surrounding an opening and a shoulder where the container widens to an increased internal volume;
- a cap secured to the mouth that comprises a body and a sleeve that is monolithic with the body and extends away from the mouth, the cap having an inner surface configured to engage with the first surface of the mouth;
- a drainage line located distally of the cap and in fluid communication with a space defined by the cap;
- and
- an O-ring located between the first surface and the inner surface and configured to retain a vacuum within the drainage system;
- and
- a retaining ring formed separately from the cap that is radially aligned with the O-ring and coaxial with the O-ring to provide a constricting force on the O-ring;
- wherein the body of the cap comprises a stop that is monolithic with the body, the stop extending outward from the mouth and along the shoulder, the retaining ring resting on the stop when the retaining ring is radially aligned with the O-ring.
A method for draining a fluid from a patient with a drainage system, the method comprising:
- placing a distal end of a drainage line into contact with a target fluid, wherein a proximal end of the drainage line contacts and provides for fluid communication with a cap that includes an inner cap surface, the cap comprising a body and a sleeve that is monolithic with the body and that extends away from outward from the body in a direction that is perpendicular to an outer surface of a mouth of a drainage container;
- moving the body proximally into engagement with the mouth of the drainage container such that an O-ring provides a seal between an outer surface of the mouth and the inner cap surface;
- and
- sliding a retaining ring proximally over the sleeve and the body of the cap such that the retaining ring is radially aligned with the O-ring and coaxial with the O-ring to provide a constricting force on the O-ring;
- wherein the body of the cap comprises a stop that is monolithic with the body, the stop extending outward from the mouth and along the shoulder, the retaining ring resting on the stop when the retaining ring is radially aligned with the O-ring.
