Fecal management methods and apparatuses (e.g., devices, systems, etc.) are described herein. The fecal management apparatuses may apply one or more fecal removal cycles of suction and irrigation (and in some examples air) to actively remove fecal material. The apparatus may control the timing of delivery of the fecal removal cycles as well as the parameters of the applied suction, irrigation and/or air within and between fecal removal cycles.

A waste collection unit including a waste container, and vacuum source to collect medical waste into the waste container. The vacuum source is disposed within a sound attenuating enclosure that defines an enclosure inlet for receiving cooling air and an enclosure outlet for discharging warmed cooling air. The sound attenuating enclosure is at least partially formed of a sound-absorbing material and may define a pocket for receiving a first end of the vacuum source. The first end of the vacuum source may engage a seat of the sound attenuating enclosure to provide a cooling air barrier. The seat may define a bottom portion of the pocket. Internal geometries of the sound attenuating enclosure may be shaped to define another air path that does not pass through the vacuum source. A plenum may be attached to the sound attenuating enclosure and define a plenum chamber to collect the warmed cooling air.

A surgical irrigation cassette comprises a cassette housing, a portion of a pump, and fluid pathways. The housing defines a chamber therein and a first console connector including a first pneumatic connector port. The pump portion includes an intake side of the pump and an output side of the pump. The fluid pathways are disposed at least in part within the chamber. A first fluid pathway, in an installed position, connects the intake side of the pump with a supply fluid container. A second fluid pathway, in an installed position, connects the output side of the pump and a handpiece. A third fluid pathway, in an installed position, connects the handpiece and a waste container A fourth fluid pathway, in an installed position, connects the first console connector and the waste container.

An aspiration system to control vacuum pressure in an ultrasonic surgical handpiece to result in improved control responsiveness during aspiration. The system comprises a console including a vacuum pump. The system includes a cassette comprising a joint that divides a vacuum path into at least two flow paths. A first joint port couples to a first flow path. A second flow path is coupled to a second joint port, a third flow path is coupled to a third joint port, and a fourth flow path is coupled to a port on a surgical waste receiver. A first sensor senses pressure in the fourth flow path and provides a waste receiver pressure signal. A second sensor senses pressure in the third flow path and provides a tip pressure signal. The controller controls a position of a first vent valve and a second vent valve based on the waste receiver pressure signal and the tip pressure signal, respectively.

A surgical cassette/pack usage tracker for tracking a number of uses for a cassette/pack to prohibit uses from exceeding a maximum amount. A usage tracker system engages with or scans a portion of the cassette/pack to determine the number of uses. In illustrative embodiments, an implement interacts with a film in the cassette after each use and determines remaining uses for the cassette/pack. In other embodiments, an implement interacts with a rotatable wheel that rotates with each use, the implement configured to permit the tracker to identify the number uses and determine remaining uses for the cassette/pack. When a maximum usage amount is reached, the tracker system may issue a warning, eject or reject the cassette/pack and/or disable the surgical device from further use.

Devices, systems, and methods interface a cassette with an eye treatment system console to provide coupling between the console and an eye treatment probe. The console may receive the cassette using a driven axial translation linkage that inhibits rotation of the cassette. The cassette may facilitate accurately positioning of a pressure sensor relative to a the console by allowing sliding movement between the sensor and a cassette body. Multiple peristaltic drives may be mounted to the console so that their rotors rotate about a common axis. An integrated mount structure may support and/or position components of the console which will interface with cassette, and an axially compressible vacuum connector of the console seal to a tapered vacuum coupler of the cassette.

A waste collection unit for collecting waste material. A reservoir is supported on a portable cart for storing a liquid on the portable cart when positioned away from a docking station. A sprinkler may be coupled to the waste container and in fluid communication with the reservoir. The sprinkler is configured to direct the liquid from the reservoir towards the waste container. The reservoir is configured to receive additional liquid from the docking station to urge the liquid from the reservoir towards the sprinkler. A prefill pump may be supported on the portable cart and in fluid communication with the waste container and operable to convey the liquid from the reservoir to the waste container. A controller may be in electronic communication with a valve assembly to control flow of the liquid from the docking station into at least one of the reservoir and a second waste container.

A surgical system for the treatment of ocular problems including a surgical cassette, a surgical console operatively coupled to the surgical cassette and further including a processor, a vacuum source positioned in-line with a vacuum regulator and a mass air flow controller, and a tank fluidly connected to the mass air flow controller, wherein the processor is configured to calculate an air flow set point in accordance with a received at least one user-defined fluid flow rate set point; and wherein the mass air flow controller modulates air flow from the tank to the vacuum source in accordance with the received the air flow set point to meet a user-defined fluid flow rate.

A system for processing fluids and filling a container with a product includes a disposable fluid circuit and reusable hardware configured to accept the disposable fluid circuit. The disposable fluid circuit includes a spinning membrane separator, first and second syringes, and a flow control cassette. The reusable hardware includes a drive coupled to the spinning membrane separator, first and second syringe pumps, the first and second syringes coupled to the first and second syringe pumps respectively, and a controller. The system also includes a syringe pump for filling low-volume containers, which syringe pump may be one of the first and second syringe pumps, or may be a third syringe pump. The syringe pump for filling low-volume containers may include a filtered vacuum/pressure source and a position detector.

The present disclosure is directed to a modular, multi-specialty pump system. The pump system includes a pump console with a motor and a sensor and a removable pump cassette attached to the pump console. The pump cassette includes a cassette identifier and the sensor can detect the cassette identifier and adjust at least one operating parameter of the motor depending on the detected cassette identifier of the pump cassette.
