A method and graphical user interface are disclosed for controlling collecting fluid from a patient. A graphical user interface in at least one first user interface element displays on a display unit information related to at least one first collection container connected to a first suction channel, and in at least one second user interface element displays information related to at least one second collection container connected to a second suction channel. Also information regarding fluid collected from a patient to at least one of the collection containers may be displayed in a third user interface element.

An assembly is disclosed for collecting fluid during a medical or a surgical operation. The assembly can include a canister having an openable lid and a collection liner. The collection liner can include a closed bag portion and an inlet for a collection container. The inlet has a first end and a second end, which opens into the bag portion. The bag portion is placed inside the canister. The first end of the inlet for a collection container extends from between the edge of the canister and the edge of the lid to the outside of the canister when the lid is closed.

A fluid delivery Y-site is described that is configured to receive and control delivery of two or more fluid flows. Fluid flow is controlled within a chamber by a valve and float. Flow of a primary fluid into the chamber is reduced or halted by the movement of a valve. The valve may occlude a first flow port into the chamber in response fluid flowing from a second flow port into the chamber. A float is moveably disposed within the chamber and configured to engage the valve in response a fluid flow into the chamber from the second flow port. As fluid flow from the second flow port into the chamber is reduced or ceases, the valve and float allow the flow from the primary flow port to once again enter the chamber and exit from an outlet port.

A manifold apparatus and method of opening a valve in a medical/surgical waste collection unit. The manifold includes a base at a proximal end with the base defining an opening off center from an axis of the manifold. The manifold further includes two arcuately spaced tabs, each subtending arcs having different arcuate lengths. The manifold is positioned such that the tabs mate with at least two slots of a lock ring of the waste collection unit so as to cause the opening of the manifold to be, upon insertion into a bore of the waste collection unit, in a specific rotational alignment in the bore. The manifold is rotated within the bore to cause a valve disk to move between a first position in which the valve disk blocks fluid flow through the receiver and a second position in which the valve disk allows fluid flow through the receiver.

A canister lid (100) for a canister (600) includes an annular perimeter (101) surrounding an interior portion (102). Rather than completely surrounding the interior portion, the annular perimeter is instead interrupted by a suction conduit (103) defined by a suction duct (104) separating a first lobe (105) and a second lobe (106). The suction duct (104) intersects the annular perimeter such that the first lobe is disposed interior of the annular perimeter while the second lobe is disposed exterior to the annular perimeter. The canister lid can further include one or more ports (110,111) extending from the interior portion.

Apparatus to treat an eye with an ophthalmic laser system comprises a patient interface having an annular retention structure to couple to an anterior surface of the eye. The retention structure is coupled to a suction line to couple the retention structure to the eye with suction. Liquid is added above the eye to act as a transmissive medium. A coupling sensor is coupled to the suction line to determine coupling of the retention structure to the eye. A separate pressure monitoring circuit having a much smaller volume than the suction line is connected to the annular retention structure to measure suction pressure therein. A system processor coupled to the monitoring pressure sensor includes instructions to interrupt firing of a laser when the pressure measured with a monitoring pressure sensor rises above a threshold amount.

An apparatus is disclosed for collecting liquid from a patient. The apparatus can include positions for collection containers. A manifold is disclosed which includes a housing, and at least one port for connecting to a patient and more than one port for collection container tubes extending from the manifold to a collection container. The ports include valves which are individually operable.

The apparatus can include positions for collection containers, a pressure sensor and a manifold having a housing, at least one port for connecting to a patient, more than one port for collection container tubes extending from the manifold to a collection container and a by-pass channel for connecting to the pressure sensor.

A wound treatment appliance is provided for treating all or a portion of a wound. In some embodiments, the appliance comprises an impermeable flexible overlay that covers all or a portion of the wound for purposes of applying a reduced pressure to the covered portion of the wound. In other embodiments, the impermeable flexible overlay comprises suction assistance means, such as channels, which assist in the application of reduced pressure to the area of the wound and removal of exudate from the wound. In other embodiments, the wound treatment appliance also includes a vacuum system to supply reduced pressure to the wound in the area under the flexible overlay. In yet other embodiments, the wound treatment appliance also includes wound packing means to prevent overgrowth of the wound or to encourage growth of the wound tissue into an absorbable matrix comprising the wound packing means. In still other embodiments, the appliance may include a suction drain. In other embodiments, the appliance may include a collection chamber to collect and store exudate from the wound. In yet other embodiments, a suction bulb may be used to provide a source of reduced pressure to an impermeable overlay that covers all or a portion of the wound. Finally, methods are provided for using various embodiments of the wound treatment appliance.
