A wound irrigation system includes a first fluid including an ion rich compound having free available ions; and a second fluid including an oxidation-reduction potential increasing compound, the second fluid housed separately from the first fluid. Mixing the first and second fluids in a charging area forms an ionically charged fluid with an oxidation-reduction potential higher than a wound site oxidation-potential. The ionically charged fluid increases antimicrobial activity of the wound upon application.

Disclosed are various embodiments for an anti-reflux enema bag having a pulley restrictor that acts as a waterflow restrictor, where the enema bag is leakproof, easy-to-clean, and provides a steady flow of solution. An enema bag system includes an enema bag, a nozzle comprising a nozzle outlet, and an anti-reflux coupler positioned between the enema bag and the nozzle through which the solution passes from the enema bag to the nozzle outlet. The anti-reflux coupler comprises an inlet for receiving at least a portion of the solution from the enema bag; an outlet for expelling the solution into the nozzle; and a check valve configured to prevent reflux of the solution from the nozzle. The enema bag system further comprises a pulley restrictor configured to selectively control a speed at which the solution is introduced into the nozzle and expelled from the nozzle outlet.

A medical syringe with at least three ports, in conjunction with a urinary catheter, can be used for closed manual irrigation of a bladder. The three syringe ports are located on a port body. Each of the three syringe ports can be manually selected by rotating a barrel that has a closed end located inside the cup-shaped port body. Rotation of the barrel inside the port body occurs about an axis that is aligned with the central axis of the hollow cylindrical barrel. The system is configured to selectively fill the syringe with an input fluid, irrigate the bladder by passing fluid into and out of the urinary catheter, and drain bladder contents into a drainage vessel without ever needing to remove the syringe from the catheter.

Described is a phacoemulsification device for eye surgery that generally comprises an ultrasonically vibrating aspiration needle that withdraws ocular material from inside of the eye. The ocular material withdrawn from the eye is equally replaced with irrigation fluid provided through irrigation ports in an irrigation sleeve surrounding the aspiration needle. In the event the aspiration needle stops withdrawing ocular material, such as if it becomes occluded with a chunk of ocular material, irrigation fluid is directed to the outside of the eye via at least one irrigation aperture to keep the eye cool where the needle is ultrasonically vibrating.

A cap and container assembly is disclosed which may be used for human body cavity irrigation or other liquid dispensing activities. The cap may include a first channel extending from a base through a neck portion to an opening in a tip portion of the cap. A side body defining a second channel may extend from the first channel near the neck portion of the cap to an opening at a distal end of the side body. An axial dimension of the tip portion may extend at an angle relative to an axial dimension of the neck portion. Liquid may flow out of the first channel under the influence of gravity and as a result of control of air flow into the second channel.

Fluid management in surgical procedures. At least some of the illustrative embodiments are methods including: supplying fluid to a surgical site inside a patients body, drawing fluid from the surgical site through a first instrument by a first pump at a first flow rate, the first flow rate during the drawing responsive to expected or actual visibility within the surgical site; and then performing a surgical resection within the surgical site using the first instrument, the performing the surgical resection changes the first flow rate; and adjusting, by a fluid management system after the surgical resection, the first flow rate responsive to the expected or actual visibility within the surgical site.

Disclosed are various embodiments for an anti-reflux enema bucket system that is leakproof, easy to disassemble and clean, prevents reflux, has components that can be independently cleaned and sanitized, and controls a rate at which water is expelled from a nozzle outlet. In various embodiments, the enema bucket system includes an enema bucket having an opening at a top for filling the enema bucket with solution, a nozzle comprising a nozzle outlet, an anti-reflux coupler positioned between the enema bucket and the nozzle through which the solution passes from the enema bucket to the nozzle outlet; and tubing fluidly coupling the enema bucket, the anti-reflux coupler, and the nozzle. A pulley restrictor may selectively control a speed at which the solution is introduced into the nozzle and expelled from the nozzle outlet.

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.

Various arrangements of fluidics systems are disclosed. In one arrangement, an aspiration circuit for a fluidics system is disclosed that selectively controls aspiration. The aspiration circuit comprises an aspiration line operatively connected to a surgical instrument, an aspiration exhaust line operatively connected to a waste receptacle; an aspiration vent line connected at a first end to the aspiration line; and a selectively variable vent valve operatively connected to the aspiration vent line. The variable vent valve may be selectively moved to vary aspiration pressure within the aspiration line. Other fluidics systems are disclosed that include a selectively positionable irrigation valve that may also be incorporated into a fluidics system that includes a variable vent valve.

A cap and container assembly is disclosed which may be used for human body cavity irrigation or other liquid dispensing activities. The cap may include a first channel extending from a base through a neck portion to an opening in a tip portion of the cap. A side body defining a second channel may extend from the first channel near the neck portion of the cap to an opening at a distal end of the side body. An axial dimension of the tip portion may extend at an angle relative to an axial dimension of the neck portion. Liquid may flow out of the first channel under the influence of gravity and as a result of control of air flow into the second channel.
