Pump cassettes, wound-treatment apparatuses and methods. In some embodiments, a pump cassette comprises: a pump body having a pump chamber, an inlet valve in fluid communication with the pump chamber, and an outlet valve in fluid communication with the pump chamber; a diaphragm coupled to the pump body such that the diaphragm is movable to vary a volume in the pump chamber; and an identifier configured to store one or more properties of the pump cassette such that the identifier is readable by an automated reader to determine the one or more properties. In some embodiments, the pump cassette is configured to be removably coupled to a wound-treatment apparatus having an actuator such that the actuator can be activated to move the diaphragm.

A system includes a pump, an inlet sensor, an outlet sensor, and a controller. The pump is configured for pumping fluid in a phacoemulsification system. The inlet sensor is coupled with an inlet port of the pump and is configured to sense an inlet temperature of the fluid at the inlet port. The outlet sensor is coupled with an outlet port of the pump and is configured to sense an outlet temperature of the fluid at the outlet port. The controller is configured to take a responsive action based a difference between the inlet temperature and the outlet temperature crossing a defined threshold.

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 fluid pump system having a first fluid pump for pumping fluid from a source to a surgical site and a second fluid pump for removing fluid from the surgical site at a first predetermined rate, wherein said fluid pump system intermittently operates in conjunction with a surgical tool which, when operational, removes fluid from the surgical site at a second predetermined rate greater than said first predetermined rate, the improvement including a sensor for sensing a predetermined parameter of the surgical tool and providing an output signal indicating that the surgical tool is operating; and an actuating means responsive to said output signal to actuate said second fluid pump to remove fluid from the surgical site at second predetermined rate.

In one embodiment, an irrigated medical system includes a medical tool, an irrigation line configured to fluidically connect an irrigation reservoir storing irrigation fluid to the medical tool, and provide at least some of the irrigation fluid to the medical tool, a force sensor configured to be coupled with the irrigation reservoir, and provide a signal responsively to a force exerted by the irrigation reservoir on the force sensor over time as irrigation fluid in the irrigation reservoir is depleted, and a controller configured to find an irrigation rate of the irrigation fluid flowing in the irrigation line responsively to the signal.

Described herein is a safety system that works collectively with an automated fluid drain control apparatus and systems and clinical experts to establish protocols and methods for given patient populations to ensure that the drainage of fluid from patients is both safe and effective. It further enables the transportation of drain orders from systems external to the drain system and returns to them the drainage data on a periodic basis for inclusion into the patient chart.

A system for aspirating thrombus that includes an aspiration catheter, a tubing set connected to the aspiration catheter, a pressurization element configured to couple to the tubing set and further configured to pressurize fluid from a first fluid source or allow pressurized fluid from the first fluid source to be transferred through a supply lumen of the aspiration catheter, and a sheath through which the aspiration catheter can be advanced.

An extension conduit for use with a system for aspirating thrombus includes a passageway extending between a distal end and a proximal end of the extension conduit, and a combined hydraulic and electrical control carried on the extension conduit and configured to be activated by a user to activate an electric switch while opening a valve to allow flow through the passageway.

An apparatus for use with a cartridge having an outer surface shaped to define a ridge includes a rigid piece of material configured to lock the cartridge in place by resting against the ridge, a button, configured to move the rigid piece of material from the cartridge, thereby unlocking the cartridge, upon a pushing of the button, one or more motors, and a mechanical coupling mechanism, configured to mechanically couple the motors to the cartridge while the cartridge is locked in place. Other embodiments are also described.

An apparatus for mechanically coupling a motor to a rotor includes an outer ring including an inner surface shaped to define multiple recesses, an inner ring disposed within the outer ring and shaped to define multiple compartments having respective outer openings, which face the outer ring, and respective inner openings opposite the outer openings, and multiple gripping elements disposed within the compartments, respectively. The inner ring is configured to receive the rotor while the compartments are aligned with the of recesses, by virtue of the gripping elements sitting at least partially within the recesses. The outer ring is configured to couple with a shaft coupled with the motor such that rotation of the shaft by the motor causes the compartments to become misaligned with the recesses, thereby causing the outer ring to push the gripping elements, through the outer openings, against the rotor, through the inner openings.
