摘要:
A method of manufacturing a thin-walled polyurethane article includes dipping a shaped former into a coagulant solution and subsequently dipping the shaped former into an aqueous-phase polyurethane/plasticizer dispersion wherein the unplasticized polyurethane has a mean particle size of between about 0.5 .mu.m and 1.0 .mu.m and wherein the plasticizer causes the polyurethane particles to swell until they have a mean particle size of between about 1.5 .mu.m and 3.0 .mu.m. Articles so produced have a thickness of between 0.03 mm to 1.0 mm, a tensile strength of between 17 MPa and 60 Mpa and an elongation at break of greater than 650%.

A two layer flexible article includes a first layer of polyvinyl chloride (PVC) and a second layer of polyester polyurethane which incorporates a texturizing agent. The article preferably is a glove formed by the method of dipping a hand shaped form into a first bath containing a PVC plastisol and a second bath containing a polyester polyurethane emulsion incorporating a texturizing agent and a slip agent. In a finished glove of the present invention the PVC layer forms the outside or patient contacting surface and the polyester polyurethane with the texturizing agent and the slip agent incorporated therein forms the inner user contacting surface. Gloves of the present invention are substantially donnable without the need for donning powders.

Containers for sterile gloves having long cuffs folding over the palms, leaving the fingers exposed beyond, are disclosed such that, upon opening, only the crease of each long cuff/palm overfold can be manually grasped. In one preferred embodiment, sterile containers initially covered with removable film are designed with single openings covered by slit film to dispense multiple surgical or examination gloves. Inside the containers, the overfolded cuffs of successive gloves are folded under the flexed fingers of the first and every succeeding glove, such that the user can serially extract externally sterile gloves by grasping the crease of each long cuff/palm overfold. One bare hand grasps the crease to glove the other. Then, the ungloved hand grasps the crease of the next glove, such that the fingers of the gloved hand can be inserted under the cuff/palm overfold to glove the bare hand. As results, the external surfaces of each extracted glove are never touched by a bare finger or any other contaminated object before use on a patient. Such containers can dispense specified numbers of examination or surgical gloves. In another embodiment, multiple pairs of surgical or examination gloves, each pair with thumbs apposed toward the palms, can be dispensed with the palms touching in separate sterile envelopes, each of which unseals to expose only the creases of the cuff overfolds. Such sterile envelopes can be boxed separately or in rolls from which each package is easily separated.
摘要:
A low cost, disposable hand protector that provides a barrier between either hand and an item being handled comprises a thin contact sheet having overlying elements forming openings arrayed around a palm area for the fingers and for either thumb. The openings are formed by overlayer panels or webs which are themselves of thin sheet material. The topmost protector on a stack can be fitted on with a single insertion motion of the hand, and conforms to the hand while providing a barrier against contamination of an item being handled. The protector is released equally easily by a single motion.
