A system and method are disclosed for removing a uterus using a fluid enclosure inserted in the peritoneal cavity of a patient so as to enclose the uterus. The fluid enclosure includes a distal open end surrounded by an adjustable loop, that can be tightened, a first proximal opening for inserting an electrosurgical instrument into the fluid enclosure, and a second proximal opening for inserting an endoscope. The loop is either a resilient band extending around the edge of the distal open end or a drawstring type of arrangement that can be tightened and released. The fluid enclosure is partially inserted into the peritoneal cavity of a patient in a deflated condition and then manipulated within the peritoneal cavity over the body and fundus of the uterus to the level of the uterocervical junction. The loop is tightened around the uterocervical junction, after which the enclosure is inflated using a conductive fluid. The loop forms a pressure seal against the uterocervical junction to contain the conductive fluid used to fill the fluid enclosure. Endoscopically inserted into the fluid enclosure is an electrosurgical instrument that is manipulated to vaporize and morcellate the fundus and body of the uterus. The fundus and body tissue that is vaporized and morcellated is then removed from the fluid enclosure through the shaft of the instrument, which includes a hollow interior that is connected to a suction pump The fundus and body are removed after the uterus has been disconnected from the tissue surrounding uterus.

A patient hydration system and method wherein hydration fluid is administered to a patient and the patient's urine output is measured either by weight or some other suitable way. A controller is responsive to the patient's urine output measurement and configured to control the infusion rate to hydrate the patient based on the patient's urine output. The controller also detects abnormal patient urine output measurements and initiates corrective action in response.

Monocrystalline silicon solaode chemical etching, washing, drying method and integral processor belong to technique field of chemical etching technique and washing. It characterized in that it not only includes water, acid, alkali, but also ultrasonic participates in etching and washing course: it includes following steps: (1) ultrasonic washes and heats in advance, (2) ultrasonic removes damnification layer, (3) ultrasonic makes herbs into wool, (4) ultrasonic rinses, (5) washing with acid to counteract, (6) ultrasonic rinses, (7) cutting water, (8) hot enthalpy to dry. Positive effects of the invention are: adopting ultrasonic to etch and wash, liquid of making wool can be acted with silicon piece, similar coarseness degree can be generated on surface, perfect pyramid pattern can be obtained; it also eliminates kalium, natrium ion from alkalescent solution, and extends service life of silicon piece; pollution can be decreased, energy consumption and water source can be saved greatly, it is a practical invention.

A patient hydration system with a first infusion subsystem for infusing a patient with fluid from a first source and a second infusion subsystem for infusing a patient with fluid from a second source. A urine output measurement subsystem determines the amount of urine output by the patient. A controller is responsive to the first infusion subsystem, the second infusion subsystem, and the urine output measurement subsystem and is configured to control the first infusion subsystem based on the amount of urine output by the patient and/or the amount of infused fluid measured by the second infusion subsystem.

The invention discloses a preparation method of instant oat flour and relates to a preparation method of oat flour. The preparation method comprises the following steps: baking, cleaning, soaking, steaming and cooling oats, serving as raw materials, sequentially; glue milling the oats after pretreatment to prepare oat pulp, carrying out enzymatic hydrolysis, heating, boiling, and killing enzyme; and cooling an enzymolysis liquid, glue milling, homogenizing, drying, sterilizing and packaging a finished product. According to the preparation method disclosed by the invention, with the oats as the raw materials, by virtue of pretreatment, enzymatic hydrolysis technological treatment and spray drying, the instant oat flour which can keep multiple nutritional components and fragrance of oat is prepared; the prepared instant oat flour is moderate in taste, has self flavor of oat, keeps the soluble nutritional components in the oats, is also capable of providing extra plant proteins, fats and soluble dietary fibers and can be directly used for preparing an oat beverage; as macromolecular substances including starch, cellulose and proteins in the oats are hydrolyzed by virtue of an enzyme method, the viscosity of the starch of the oats is lowered, and the problems of water separating, gelation, precipitation and the like caused when the oats are applied to beverages are solved.

An electrosurgical medical device and method for treating cardiac arrhythmias. In one embodiment, an elongate catheter has a distal shaft end or balloon that carries an electrosurgical energy delivery surface comprising at least one electrode with a positive temperature coefficient of resistance (PTCR) surface and/or an electrode with a pressure sensitive variable resistance to provide a smart surface for controlling Rf current flow at the interface of electrosurgical surface and the tissue. The electrosurgical surface then can limit or modulate Rf energy delivery through the surface in response to the temperature of the tissue or the engagement pressure of the surface against the engaged tissue. In operation, the smart electrosurgical surface can prevent arcing at the electrode-tissue interface, and thus control ohmic heating to prevent tissue desiccation, charring and emboli formation.

A process for improving the acid intensity stability of solid acid catalyst containing heteropoly acid or its salt (0.5-100 wt.%) features that said heteropoly acid or its salt has central atom (P or Si) and coordinating atom chosen from W, Mo and V, and there is water in reaction atmosphere.

In accordance with one aspect of the invention a process for applying an abradable coating to a component includes cold spraying an abradable coating material in particles towards a target surface of the component.

A process for the removal of an amine captureable gas from a feed gas stream using an amine solvent, the process comprises (a) contacting the feed gas stream with a lean amine solvent to form a rich amine solvent, wherein heat stable salts are present in the rich amine solvent; (b) stripping amine captureable gas from the rich amine solvent to form the lean amine solvent and an overhead reflux stream; (c) periodically contacting at least a portion of one or both of the lean amine solvent and the rich amine solvent with an anion exchange resin to form a first heat stable salt lean amine solvent; (d) periodically regenerating the anion exchange resin, wherein during the regeneration of the anion exchange resin, at least a portion of the reflux stream is used to wash the amine solvent from the anion exchange resin to produce a second heat stable salt lean amine solvent; and, (e) recycling at least a portion of the first and the second heat stable salt lean amine solvent for use in capturing the amine captureable gas from the feed gas.

The present invention relates to a process comprising the steps of reacting a reactive mixture comprising at least one silicone-containing component, at least one hydrophilic component, and at least one diluent to form an ophthalmic device having an advancing contact angle of less than about 80°; and contacting the ophthalmic device with an aqueous extraction solution at an elevated extraction temperature, wherein said at least one diluent has a boiling point at least about 10° higher than said extraction temperature.

A dispenser for readily attaching to a roll-type toilet-tissue holder and dispensing moist towelettes from a roll of the moist towelettes. The roll-type toilet-tissue holder is disposed in a wall and has a spindle that is axially spring loaded to facilitate insertion into and removal from the roll-type toilet-tissue holder. The dispenser includes a container. The container contains the roll of the moist towelettes to prevent dehydration thereof prior to dispensing, dispenses the moist towelettes from the roll of the moist towelettes contained in the container, and has the spindle of the roll-type toilet-tissue holder pass freely therethrough and attach to the roll-type toilet-tissue holder so as to allow the container to readily attach to the roll-type toilet-tissue holder.
