Irrigation is the application of controlled amounts of water to plants at needed intervals. Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall. Irrigation also has other uses in crop production, including frost protection, suppressing weed growth in grain fields and preventing soil consolidation. In contrast, agriculture that relies only on direct rainfall is referred to as rain-fed or dry land farming.
Irrigation and drainage based on hydrodynamic unsaturated fluid flow
InactiveUS6918404B2Improve the level ofHigh porosityPipeline systemsMachines/enginesEnvironmental engineeringPorous microstructure
Irrigation and drainage systems are disclosed, including a saturated zone and at least one pipe in communication with the saturated zone. The pipe(s) can be configured to comprise a tubarc porous microstructure for conducting water from the saturated zone to an unsaturated zone in order to drain the water from the saturated zone. The water can be delivered from the saturated zone to the unsaturated zone through the tubarc porous microstructure, thereby permitting the water to be harnessed for irrigation or drainage through the hydrodynamic movement of the water from one zone of saturation or unsaturation to another.

Removable adapter for phacoemulsification handpiece having irrigation and aspiration fluid paths
Current phacoemulsification handpieces require rigorous cleaning after each procedure because the aspiration and irrigation pathways for fluids are integral to the handpiece. According to the present invention, a removable horn extension and nosecone may be used with a phacoemulsification handpiece to allow for disposable fluid pathways exterior to the handpiece. This will reduce the cleaning time and effort, reduce cross-contamination, and increase the lifespan of the handpiece. Furthermore, the current invention allows different horn extensions to be used to excite different motions at the tip of the handpiece, depending on the preference of the surgeon.

Automated laparoscopic lens cleaner
An apparatus and method for cleaning the objective lens of a laparoscope, endoscope, or coeloscope during surgery and also removing the solution and debris during and after the cleaning. The result is obtained by using a rigid hollow split sheath for the scope. The split sheath has two separate channels. One channel is for irrigation and the cleaning fluid flows through this channel to be directed onto the lens. The other channel is for suction to remove the solution and debris during and after the cleaning. Control buttons located at the operator's end activate the irrigation and suction functions. The control buttons for irrigation and suction are fabricated into an existing valve type device which can regulate either of these functions. In addition, two ports, one for irrigation and one for suction emerge from the operator's end to connect to the appropriate tubing for irrigation and suction. A rubber ring device screws down at the operator's end allowing the surgeon to secure the sheath to the scope and prevent any leakage of the standard carbon dioxide gas used to distend the abdomen for operative laparoscopy in the patient.

Cannula that provides bi-directional fluid flow that is regulated by a single valve
A cannula useful for endoscopic surgery. The cannula includes an outer tube in which an inner tube is removably seated. A surgical instrument can be positioned at the surgical site through the inner tube and irrigation fluid can be flowed to the surgical site through the inner tube. The tubes are spaced from each other to form a channel through which fluid can be selectively withdrawn from the surgical site. Fluid flow to and from the surgical site through the cannula is controlled by a valve assembly that has a single valve cock. The valve cock can be positioned to allow maximum irrigation flow / no suction flow or no irrigation flow / maximum suction flow. Bores internal to the valve cock are shaped so that, while the suction flow is initially incrementally increased, the irrigation flow is at a constant level.
