Disclosed are irrigation systems and methods, which can be used for rectal/anal irrigation. One example system includes a reservoir for an irrigating liquid, a probe for arrangement in a user, tubing providing fluid communication between the reservoir and probe, and an electrical pump for indirectly pumping irrigation liquid from the reservoir to the probe through said tubing. The electrical pump is controllable to assume a plurality of predetermined flow rates. The system includes an electrically operable valve to continuously control a degree of openness of the tubing, a flow sensor to measure an actual flow rate of the irrigation liquid in the probe, and a controller to obtain a desired flow rate, and control the flow rate of the electric pump to one of the plurality of flow rates exceeding the desired flow rate, and to continuously regulate the electrically operable valve based on the measured actual flow rate.

The present patent application relates to a device for rinsing body cavities, as they are used, for instance, in the hysteroscopy, that determines, by using flow sensors, the introduced and discharged amount of rinsing liquid. Based on these flow measurements, it can be determined whether a relevant amount of liquid has been left in the patient.

A wound therapy system includes an instillation fluid canister configured to contain an instillation fluid, a pump fluidly coupled to the instillation fluid canister and operable to deliver the instillation fluid from the instillation fluid canister to a wound, a user interface configured to receive user input indicating one or more geometric attributes of the wound, and a controller electronically coupled to the pump and the user interface. The controller is configured to determine a volume of the wound based on the user input, determine a volume of the instillation fluid to deliver to the wound based on the volume of the wound, and operate the pump to deliver the determined volume of the instillation fluid to the wound.

Surgical tools are provided herein that are configured to apply suction and irrigation at a surgical site during the course of a surgical procedure. A surgical tool can include a handle that has a suction flow path configured to provide suction therethrough and an irrigation flow path configured to provide irrigation therethrough. The suction flow path and the irrigation flow path can share a common path along at least partial lengths thereof. An elongate shaft can extend distally from the handle and can have an inner lumen that is in communication with the suction flow path and the irrigation flow path. The inner lumen can thus be configured to provide suction from the suction flow path to a surgical site to remove matter therefrom and to provide irrigation from the irrigation flow path to the surgical site to provide fluid thereto.

An ophthalmic irrigator-aspirator has a handpiece with aspiration and irrigation openings through its distal end. A tip component connects to the handpiece and has an aspiration cannula. A flexible sleeve has an annular hub for watertight connection to the handpiece or a base portion of the tip. The sleeve has an intermediate portion that forms a channel for an irrigation fluid along the exterior of the cannula to an irrigation port in the sleeve. The distal end portion of the sleeve is sized for a watertight connection over the distal portion of the cannula. Such distal end portion of the sleeve has an aspiration port in communication with the cannula aspiration port. The sleeve proximate, intermediate, and distal portions are integral with each other and are formed of a resilient material that allows the sleeve to be tightly fitted on the handpiece or tip base portion and the cannula.

A medical/surgical lavage unit including internal ribs that extend into a void space of a suction tube attached to the lavage unit.

A weighing system for medical applications may include a basin that has a base and a sloped sidewall that collectively form a bounded cavity with open top surface that receives and holds the material to be weighed. The basin may be free floating above the weighing device within a restricted range of travel. In some examples, the weighing system includes a thermal treatment device to adjust the temperature of the material in the basin. The rate at which heat is delivered to the basin may vary depending on the weight of the contents in the basin.

A lavage handle for facilitating at least one of an irrigation function and a suctioning function at a target zone preferably includes a portable body, a power-operated fluid-displacing mechanism in communication with said body wherein said fluid-displacing mechanism has one of a first operating mode for inducing outward irrigation of fluid towards the target zone and a second operating mode for inducing inward suction of fluid from the target zone. An actuation mechanism is located at said body and operable communicated with said fluid-displacing mechanism such that said fluid-displacing mechanism is selectively operated in at least one of said first operating mode and said second operating mode. The actuation mechanism may include an irrigation-inducing mechanism and/or a suction-inducing mechanism.

Systems, apparatuses, and methods for instilling fluid to a tissue site in a negative-pressure therapy environment are described. Illustrative embodiments may include a pneumatically-actuated instillation pump that can draw a solution from a solution source during a negative-pressure interval, and instill the solution to a dressing during a venting interval. A pneumatic actuator may be mechanically coupled to a disposable distribution system that can provide a fluid path between the solution source and a distribution component. A bacterial filter may be disposed in the fluid path between the actuator and the distribution component to prevent contamination of the actuator during operation. The distribution system may be separated from the actuator and disposed of after operation, and the actuator may be re-used.

A method for maintaining anterior chamber intraoperative intraocular pressure (IOP) is provided by receiving and/or detecting variables of a surgical system and utilizing those variables to monitor intraoperative IOP. Determining an IOP in real time during a surgical procedure either provides a notification to an eye surgeon or allows a target IOP of the anterior chamber of a patient's eye to be set and maintained.
