A method and solution for perioperatively inhibiting a variety of pain and inflammation processes at wounds from general surgical procedures including oral / dental procedures. The solution preferably includes multiple pain and inflammation inhibitory at dilute concentration in a physiologic carrier, such as saline or lactated Ringer's solution. The solution is applied by continuous irrigation of a wound during a surgical procedure for preemptive inhibition of pain and while avoiding undesirable side effects associated with oral, intramuscular, subcutaneous or intravenous application of larger doses of the agents. One preferred solution to inhibit pain and inflammation includes a serotonin2 antagonist, a serotonin3 antagonist, a histamine antagonist, a serotonin agonist, a cyclooxygenase inhibitor, a neurokinin1 antagonist, a neurokinin2 antagonist, a purinoceptor antagonist, an ATP-sensitive potassium channel opener, a calcium channel antagonist, a bradykinin1 antagonist, a bradykinin2 antagonist and a mu-opioid agonist.

A method and solution for perioperatively inhibiting a variety of pain and inflammation processes at wounds from general surgical procedures including oral / dental procedures. The solution preferably includes at least one pharmacological agent that is a soluble receptor tyrosine kinase, and optionally additional multiple pain and inflammation inhibitory agents at dilute concentration in a physiologic carrier, such as saline or lactated Ringer's solution. The solution is applied by continuous irrigation of a wound during a surgical procedure for preemptive inhibition of pain and while avoiding undesirable side effects associated with oral, intramuscular, subcutaneous or intravenous application of larger doses of the agents.

A closed system irrigation connector for use with both 3-way and 2-way urinary catheters is disclosed. The connector fits all urinary catheters and accepts continuous irrigation sets as well as all bulb, piston, and Toomey catheter tip irrigation syringes. The connector eliminates the use of catheter plugs and reduces the mess and leakage often associated with present urinary catheter irrigation procedures. The connector converts an open procedure to a closed system procedure protecting the patient from outside contamination to reduce urinary tract infections as well as the clinician from potentially infectious body fluids. It comprises an assembly of a plastic housing with an internal silicone diaphragm slit valve and a plastic entrance port that are unitized in assembly by sonic welding. The entrance port forms a tapered wedge lock engagement with irrigation sets as well as catheter tip irrigation syringes.

he present invention relates to a device for unpowered irrigation and fertilization, and to an unpowered pot cultivation system using same, which are capable of performing continuous irrigation and fertilization to a pot by using a single supply source without consuming electric or mechanical energy. The system comprises: a pot holder provided with a collecting recess in which water or a nutrient solution can be collected, and configured such that the bottom of the pot can be immersed in water; a water tank holder on which a water tank can be seated; a linking passage connecting the water tank holder to the pot holder; a valve unit mounted on the water tank so as to be opened and closed by means of the movement of a moving member; and a water level controller configured to move the moving member according to fluctuations in the water level of the collecting recess, in order to uniformly maintain the water level in the collecting recess.

The invention provides a method for manufacturing a continuous micro water amount irrigation pipe, a continuous micro water amount irrigation pipe manufactured by the method, a method for irrigating by using the continuous micro water amount irrigation pipe, and application of the continuous micro water amount irrigation pipe to agricultural irrigation. The method for manufacturing the continuous micro water amount irrigation pipe comprises the following steps: preprocessing filling materials; mixing the preprocessed filling materials with high-pressure polyethylene resin by preset ratio of parts by weight to manufacture filling granule materials; manufacturing the filling granule materials into a preformed pipe; leading the preformed pipe into a high-temperature extraction machine to be continuously extracted to manufacture the continuous micro water amount irrigation pipe. The method can be used for manufacturing the continuous micro water amount irrigation pipe of which the pipe wall is provided with micro holes. After the continuous micro water amount irrigation pipe is filled with water, the water can leak out of the micro holes, the water yield is accurate and can be adjusted, and the continuous irrigation by the micro water amount through the way of continuous water supply for 24 hours is realized for crops in a full life circle way.

An agricultural potassium-fertigation method for emitter-irrigation potassium-plus fertigation feeds a potassium-plus nutrient feedstock comprised of potassium formate and additional yield-assist constituent(s) and water to an active emitter-irrigation system discontinuously, at levels of 0.15 to 50 gal. / min, during one to six nonconsecutive irrigation days during a crop cycle.
