摘要:
An incise drape suitable for use in surgical procedures. The drape comprises a substantially transparent flexible film that has at least a portion of one major surface coated or covered with a pressure sensitive adhesive, and a two liners removably covering the adhesive. Each liner has a handle spaced from the opposite side edges of the film, and a body portion attached to the handle. The body portion of each liner extends along the adhesive from handle in the direction away from the other liner. The drape is repeatedly folded over from the opposite side edges of the film toward the handles so that the drape may be unfolded and the adhesive exposed by pulling the handles apart.
摘要:
A face mask including a face-contacting layer, an outer cover layer, a polymeric microfiber mat disposed between the face-contacting layer and the outer cover layer, and a non-woven fibrous mat disposed between the face-contacting layer and the outer cover layer. The non-woven fibrous mat includes polymeric fibers and a surface energy reducing agent. The face-contacting layer, the cover layer, the polymeric microfiber mat, and the non-woven fibrous mat cooperate with each other to allow gas to pass through the mask while inhibiting the passage of liquid through the mask.

The present invention provides a water-curable resin composition for use in an orthopedic cast composed of a water-reactive alkoxysilane terminated resin, having at least one hydrolyzable group per molecule. The resin composition has a viscosity of no greater than about 500 Pa-s under ambient conditions and contains less than about 1 wt-% of a solvent, based on the total weight of the resin composition.

The present invention provides a narrow orthopedic casting tape which can be handled in longer lengths suitable for economical production of coated fabric products. The narrow casting tape of the present invention is knitted as a wide fiberglass fabric with at least one removable connecting yarn in the length (i.e., warp) direction of the fabric which acts to connect two narrower strips of fiberglass fabric. The removable connecting yarn is subsequently removed from the fabric by a heat treatment process which separates the wider fabric into two narrower fabrics and also heat sets the fabric. Alternatively, the removable connecting yarn may be removed from the fabric by a dissolution process. Narrow fabrics of the present invention can also be constructed of organic yarns.The present invention also provides a tearable orthopedic casting tape which has a high degree of extensibility. The tearable casting tape of the present invention is knitted as a wide fabric, preferably fiberglass, with at least one tearable connecting yarn in the length direction of the fabric which acts to weakly connect two or more narrower fabrics. The tearable connecting yarn is capable of being easily torn or slit causing the fabric to separate into narrower webs.
摘要:
The present invention relates to orthopedic splinting articles and methods for forming orthopedic splints at least part way around an animal body part. The splinting articles comprise a unitary blank formed of an open-celled foam sheet impregnated with a water curable, isocyanate functional, polyurethane prepolymer resin. The blank is dimensioned to extend the length of the body part to be immobilized and to partially, but preferably not completely, extend around the circumference of the body part. Upon activation of the resin impregnated foam sheet and molding the same around the body part, an orthopedic splint is formed. The present invention further relates to the use of such resin-impregnated foam materials as walking heels or laminates betweeen casts and walking heels, as supports for orthotic devices such as arch supports for foot orthotics, and as protective coverings for animal hoofs.
摘要:
Chemically-modified collagen is prepared by reacting native collagen with a di or tri-carboxylic acid halide, di or tri-sulfonyl halide, di or tri-anhydride, or di or tri-reactive active ester coupling agent. The reaction is done in a controlled manner so that the degree of cross-linking is limited. Any remaining lysine epsilon amino groups present in the coupled collagen product may be converted to ureido, .beta.-malicamino carboxyamido or sulfonamido groups by isocyanate, epoxy succinic acid, acid halide, anhydride, sulfonyl halide or active ester aminemodifying agents. The resultant soluble product when dissolved in a physiological buffer provides a viscoelastic solution having therapeutic application in a variety of surgical procedures, particularly in ophthalmic surgery. This viscoelastic solution "melts," i.e., exhibits a dramatic loss of viscosity, when subjected to temperatures of between 32.degree. and 48.degree. C. The resultant insoluble product is suspended in physiological buffer and useful in tissue augmentation. The suspension containing the insoluble product exhibits a dramatic loss in viscosity at temperatures between about 40.degree. and 70.degree. C.

The present invention pertains to nonwoven webs, and multi-component fibers comprising polydiorganosiloxane polyamide as well as method of making microfibers and multi-component fibers comprising a polydiorganosiloxane polyamide copolymer.
摘要:
Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. A spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. A meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. Antishrinkage and antistatic additives are also added to the fibrous webs. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing.
