A trans-anal irrigation (TAI) system adapted for self-use includes an irrigation head supplied with water from a reservoir by a pump or by gravity feed. The irrigation head has either internal or external structures for releasably retaining the head in a user's rectum during the water flow portion of a TAI process. A guide member arm may be provided for manipulating the irrigation head for both insertion and removal. The irrigation head is reliably attached to the guide member arm. The guide member arm may include an integral manual pump.

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. In one example embodiment, a system for providing negative-pressure and instillation to a tissue site may comprise a negative-pressure device and an instillation device. The negative-pressure device may comprise a negative-pressure source and a controller electrically coupled to the negative-pressure source. The instillation device may comprise a dosing valve having a dosing chamber including a dosing outlet configured to be fluidly coupled to a fluid port and a dosing inlet configured to be fluidly coupled to a source of instillation solution. The dosing valve may also have a working chamber including a biasing element operably engaged to the dosing chamber and configured to be fluidly coupled to the negative-pressure source. In some embodiments of the system, the instillation device may further comprise a wireless transceiver configured to communicate with the controller, and at least one sensor coupled to the wireless transceiver to provide a signal indicative of an operating condition of the dosing valve, and wherein the wireless transceiver is configured to communicate the at least one signal to the controller.

A low-cost and simple-to-use system and method to facilitate a prophylactic pleural lavage protocol at the time of thoracostomy tube placement for traumatic hemothorax in order to reduce the need for secondary intervention for the management of retained hemothorax. The invention may be used in conjunction with existing chest tubes and be administered at the time of initial chest tube placement, and continued at the bedside (by a bedside nurse) over the duration of chest drainage, as necessary. The system includes an operator device that semi-automatically administers a pleural lavage protocol consisting of saline instillation, and suction to slow the clotting process, prevent “gelling” of blood, and maintain drainability.

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.

Subject matter of the invention is a method for determining the difference in height level between a medical fluid pump and the body cavity of a patient for the correction of the measurement of the fluid pressure existing at the outlet end.

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.

An irrigator system for delivering a volume of fluid from a fluid source to an abscess or wound. The irrigator system includes a fluid source connector for removably connecting to the fluid source, a fluid delivery nozzle for delivering the fluid to the abscess or wound, and a shield removably positioned around the fluid delivery nozzle to protect the fluid delivery nozzle.

A fluid management system may include an inflow pump configured to pump fluid from a fluid supply source to a treatment site within a patient at a flow rate; and a controller configured to operate at a target flow rate in a flow control mode. In the flow control mode, the controller may be configured to maintain the target flow rate while monitoring a measured pressure communicated to the controller from a pressure sensor. When the measured pressure reaches a preset pressure threshold, the controller may be configured to automatically switch from the flow control mode to a pressure override mode in which the controller automatically reduces the flow rate below the target flow rate to return the measured pressure at or below the preset pressure threshold.

Featured is a closed loop surgical system including one or more control units that are configured to form a fluid control subsystem for fluid control and a device control subsystem for controlling a surgical device. The two control subsystems in combination provide an automatic self-managed closed loop system for the control of fluid into and out of the surgical site by means of intelligent communication and for maintaining a preselected pressure desired by the surgeon. In particular embodiments, this is accomplished by utilizing empirically correlated motor speed and load measurements, based on supplied current, from the surgical resection device when using its specific resection capability. For example, automatically adjusting fluid flow responsive to changes in loading of a surgical device or automatically sensing a load change for the surgical device during a surgical procedure and automatically changing (increasing or decreasing) fluid flow responsive to the load change.

A system for managing fluid levels in phacoemulsification surgery is disclosed. The system comprises a surgical console having at least one system bus communicatively connected to at least one computing processor capable of accessing at least one computing memory associated with the at least one computing processor, and at least one sensor associated with the surgical console for providing at least one signal indicative of the presence of liquid, wherein the at least one sensor is in communication with at least one level sensing device of a cassette associated with the surgical console.
