A wound dressing comprising a backing layer and a skin facing layer and an absorbent pad, wherein the absorbent pad is sandwiched between the backing layer and the skin facing layer, and the two layers constitutes an envelope, the absorbent pad has an expansion of surface area, when fully expanded, of at least 10%, and wherein the surface area of said envelope is at least 10% larger than the surface area of the non-expanded absorbent pad. The envelope provides room for expansion of the absorbent pad without buckling or folding of the absorbent pad.

The invention discloses a medical composite dressing for wound repair. The dressing comprises an inner layer which is in contact with a wound, a middle layer and an outer layer. The dressing is characterized in that: the inner layer is a chitosan / polyvinyl alcohol / oxidized sodium alginate blended nano-fiber antibacterial layer; the middle layer is an aerogel moisture absorption layer prepared by subjecting a sodium alginate / polyvinyl alcohol / sodium carboxymethyl cellulose nanofiber membrane to shearing and freeze-drying treatment; and the outer layer is a non-woven fabric breathable layer, andthe inner layer, the middle layer and the outer layer are compounded through medical glue. According to the composite dressing, the mechanical property of the dressing is improved by utilizing an electrostatic spinning technology. Meanwhile, the nanofiber membrane prepared according to the electrostatic spinning technology and the nanofiber membrane aerogel obtained through aftertreatment have high porosity and large surface area, the excellent breathability can be achieved while the high moisture absorption and moisture retention performance is guaranteed, exudate diffusion is reduced, the skin is kept clean, and the dressing can be widely applied to recovery treatment of various wounds.

An ergonomic, contoured urinal floor mat for use with wall-urinals with the purpose of positioning a user center, up and toward a wall-urinal so as to prevent urine spillage and drippings from reaching floor below a wall-urinal. The floor mat consists of a heavy duty, permanent material with topside anti-slip and floor conforming anti-skid surfaces and is designed with three unique contouring angles which, in combination, elevates heels above toes, spreads legs, pushes toes outward, pulls heels inward, and creates a lift in the inner arch of the foot. The system also incorporates a replaceable drip tray, located between the users' legs and the urinal lip (to catch the inevitable last drops), a topside perimeter gutter (for complete urinal misses), and underside seal (to prevent liquids seepage under mat). If spills do occur, the overall contouring guides liquid into the gutter and keeps the topside foot areas dry.

A laminated layer fuel cell includes a solid polymer electrolyte layer, a pair of catalyst layers, and a pair of gaseous diffusion electrode layers, one of the pair of catalyst layers and one of the pair of gaseous diffusion electrode layers being formed on one side of the solid polymer electrolyte layer, and the other of the pair of catalyst layers and the other of the pair of gaseous diffusion electrode layers being formed on the other side of the solid polymer electrolyte layer, wherein the one of the pair of catalyst layers and the one of the pair of the gaseous diffusion electrode layers constitute a composite electrode layer, and the composite electrode layer has an amount in a range of 10000 to 12000 ml·mm / cm2 / min of air flow permeation in the thickness direction in a dried state.

The present invention provides a drum-type washing and drying machine which can reliably prevent the intruding of washing foam generated in drum into the places of heating unit, air supplying unit, etc. which are concealed in an air supplying and heating channel at a state of overmuch foam generation. The drum-type washing and drying machine can respectively detect the overmuch foam generation through setting a first electrode (62) and a second electrode (64) which are used for detecting the foam generated in the washing course at a warm air supplying channel (61) homogeneous to the downstream side of air supplying and heating channel (67) and a dehumidifying unit (63) homogeneous to the upstream side, thereby reliably preventing the infusing phenomenon generated by the adhering of washing foam on the air supplying and heating channel (67) and an air supplying fan (66), and increasing the reliability of the heater and air supplying fan.

The invention discloses a fresh ginger / breeding ginger overwintering storage method, comprising the following steps of building a cellar for storage on the indoor ground in a surrounding way; paving a ground film on the bottom of the cellar, covering the ground film and the inner walls of the cellar with dry straw, and stacking breeding ginger layer by layer in the space surrounded by the dry straw in a way of separating the layers of breeding ginger with the dry straw; after the completion of stacking the breeding ginger, covering the top part of a ginger stack with the dry straw, and wrapping the outer walls of the cellar with a plastic film for sealing; implementing overwintering management. According to the fresh ginger / breeding ginger overwintering storage method, the problem that when a traditional outdoor cellar storage method for the breeding ginger is adopted, frost damage or heat damage is likely to occur during the overwintering process is solved; the loss of the breeding ginger during the storage period is effectively decreased.

The inventive disclosure contained herein is generally directed to a class of medical bandages that in many embodiments are effective in the treatment of various types of tissue burns, whether be burns due to thermal burns, sun exposure, or rashes. Such products can include a plurality of specialized bandages and wraps that incorporate an extremely thin layer of thermally conductive metal (often aluminum) at the base of a substrate adapted to be in direct contact with a burn wound, while manufacturing the top side of the aluminum substrate to have a heat-dissipation-enhancing topography to help cool burns faster by enhancing thermal-convection properties. The bandage can also feature a thermochromic indicator for users to realize the thermal-cooling status of a burn to which a bandage has been applied.
