Methods, devices, and systems for laser eye surgery generally make use of a console that interchangeably accepts multiple types of eye treatment cassettes. The cassettes enable one or both of displacement-based or vacuum-based aspiration. The console and the cassette may communicate to establish the functionality of the installed cassette by utilizing a component indigenous to the operation of the cassette. A dual-mode cassette may include a separable holding tank for enabling vacuum-based aspiration. A displacement-based pump may be provided to drain the holding tank while the vacuum system continues to aspirate fluids. A vacuum sensor for controlling the flow of aspirated fluids may have three ports for communicating with a handpiece, a displacement-based pump, a vacuum-based pump, or an irrigation source. The handpiece may be vented during vacuum-based aspiration by opening a vent valve interposed between the handpiece and the vacuum source.

A system and method of collecting and disposing of fluid during a medical procedure. Fluid is drawn from a fluid source into a first reservoir in communication with a vacuum source. The fluid passes through an open fluid transfer valve into a second reservoir in communication with the vacuum source. While the fluid continues to be drawn into the first reservoir, the fluid transfer valve is closed after a predetermined volume of the fluid passes into the second reservoir. The fluid collected in the second reservoir is measured and evacuated from the second reservoir. The fluid transfer valve is opened and the steps are repeated until the medical procedure is completed while the first reservoir remains in uninterrupted communication with the vacuum source during the medical procedure such that fluid is capable of continuing to be drawn into the first reservoir without interruption.

A surgical collection assembly for filtering material from liquid obtained during surgery. A jar having an inlet and an outlet each adapted for connection to a suction line. A set of orientation features to position an upper portion of a collection basket within the jar such that an upper portion of the collection basket does not impede a flow of material entering the jar through the inlet. A bottom surface with a pattern of recessed paths in the bottom surface, the pattern of recessed paths connected to the outlet. A plunger assembly that may be reversibly attached to the jar so that a distal end of a plunger may be used to compress collected material within the collection basket to help remove fluid from the collected material. For certain uses, the surgical collection assembly may have a simple jar lid without an integrated plunger.

A system, method, and apparatus for the collection of surgical/wound fluid from a subject patient with the capability of simultaneous fluid removal from a plurality of such wounds and/or wound through the utilization of a single pump device worn by such a patient. Such a system, method, and apparatus allow for such a single pump device to collect surgical/wound fluid within a single site collection component attached to or associated with such a single pump device. Multiple fluid transfer lines may be incorporated with the single pump device leading to such plurality of wounds and/or wound sites for greater versatility and comfort for the subject patient, as well as cleaner removal capabilities than in the standard apparatus systems and method currently undertaken within the industry.

A medical waste collection system for collecting medical waste material, and a manifold for filtering the waste material and/or coupling a suction tube to the system. The system may include a receiver in which the manifold is configured to be inserted in a proximal direction to facilitate an inlet mechanism moving correspondingly in the distal direction. The manifold may include an arm, a spine, a lock element, and/or a catch each having a surface with a relative position in the proximal-to-distal direction. The rim and the catch may be spaced apart by a void, and the rim may be positioned below the catch. The housing may include a body portion, a first leg extending proximally from the body portion, and a second leg spaced apart from the first leg to define the void. The rim may be on the first leg, and the catch may be on the second leg.

Manifold for a medical/surgical waste collection assembly. A shell includes a proximal end base, and a lip extending proximally from the proximal end base. The lip extends around an outlet opening defined in the proximal end base that is off-centered to a longitudinal axis of the shell. A cap including a cap head is coupled to a side wall of the shell. A drip stop may be seated within a space defined by the lip to cover the outlet opening. An arcuate section of the lip may be flush with an adjacent section of the side wall. The cap head may define a through hole, and a flapper valve unit may be coupled to the cap head with another component having ears extending through the through hole. A fence may extend from the cap head and configured to be grasped by a user.

A manifold for a medical/surgical waste collection assembly. The manifold includes a housing shaped to be removably received within a manifold receiver of the medical/surgical waste collection assembly. An inlet fitting is coupled to the housing and adapted to be coupled with a suction line. An outlet opening is in fluid communication with the inlet fitting to define a fluid communication path from the suction line to the outlet opening and through a filter. The manifold includes a data carrier storing data useable to regulate operation of the medical/surgical waste collection assembly. The data carrier may include a radiofrequency identification tag having memory storing data suitable for determining whether the manifold is usable with the medical/surgical waste collection assembly. The RFID tag is adapted to be in electronic communication with a data reader when the manifold is coupled with the manifold receiver for communicating the data from the manifold.

A system (1) for collecting liquid, including a main collecting chamber (10), a main duct section (11, 12, 13) connected to the main collecting chamber (10) in a fluid-communicating manner, and an auxiliary collecting chamber (20, 30, 40). The system (1) has an auxiliary duct section (21, 38, 39) connected to the auxiliary collecting chamber (20, 30, 40) in a fluid-communicating manner for connection to the main duct section (11, 12, 13). The main duct section (11, 12, 13) and the auxiliary duct section (21, 38, 39) form a duct (35, 36, 37) when the main duct section is connected to the auxiliary duct section. A water-soluble closing component (14, 15, 16) closes the duct (35, 36, 37). A hygienic collecting device for liquid, which has a short evacuation time and a flexible collection volume, is provided with the system (1).

A medical device can include a reservoir for creating a vacuum and storing fluid, an input port for receiving the fluid from a patient, an input valve that prevents the fluid from flowing from the reservoir through the input port, and a connector. The connector can have a locking interface that mates with a needleless syringe, and a valve that opens to permit flow of the fluid through the connector when connected to the needleless syringe but closes to prevent the flow when not connected. Other aspects are described and claimed.

A fluid management system including a pass-through fluid volume measurement system to provide continuous measurement of fluid returned from a surgical site during transit to a waste collection system. The pass-through fluid volume measurement system eliminates the need to physically replace full fluid collection containers during the medical procedure with new, empty fluid collection containers.
