摘要:
A bolus for administering medicament containing the medicament in a bio-erodible polymer having a shape or size so that it is retained in the rumen for at least two weeks, having a fine mesh completely encasing the bolus, which can contain a heavy metal core to give it weight, or can be in two segments connected by a spring, or a flexible polyurethane band, which changes position after being administered to the animal.
摘要:
A synthetic absorbable hemostatic composition for use in the control of osseous hemorrhage, comprising polydioxanone in a biocompatible base, the polydioxanone having a sufficiently low inherent viscosity such that the composition possesses a putty-like consistency at room temperature. The preferred composition is one in which the polydioxanone comprises between 65% and 75% by weight of the composition.
摘要:
Ultraviolet light absorbing polymer compositions comprising copolymers of 2-Hydroxy-5-acrylyloxyphenyl-2H-benzotriazoles with one or more other monomers copolymerizable therewith, particularly acrylic monomers are useful in the manufacture of occular devices, particularly intraoccular lenses and contact lenses. Polymers of the disclosed benzotriazoles may be added to other organic materials to impart ultraviolet absorbing properties thereo.
摘要:
An absorbable hemostatic composition for use in the control of osseous hemorrhage, comprising a biocompatible fatty acid salt in a biocompatible base, said composition having a putty-like consistency at room temperature. The preferred composition is one in which the fatty acid salt is calcium stearate.
摘要:
The compounds 2'-hydroxy-5'-(hydroxyalkyl)phenyl-2H-benzotriazoles are useful as intermediate alcohols in the preparation of corresponding 2'-hydroxy-5'-acrylyloxyphenyl-2H-benzotriazole monomers, which in turn are copolymerizable with ethylenically unsaturated monomers, particularly acrylic monomers, to impart ultraviolet absorbing properties to the resulting copolymers.
摘要:
A synthetic absorbable hemostatic agent for use in the control of osseous hemorrhage, comprising a copolymer of lactide and glycolide containing from about 30% to 70% lactide on a molar basis, and having a molecular weight such that it possesses a putty-like consistency at room temperature. The preferred agent has a lactide/glycolide molar ratio of 65:35 and a molecular weight of between 2000 and 2500 Dalton. The agent may also be mixed with a biocompatible base.
摘要:
Non-metallic, bio-compatible hemostatic clips of absorbable or nonabsorbable materials are formed by two legs joined with a resilient hinge. One leg terminates in a hook member which secures the other leg when the clip is closed. The clip applier is a forceps-type instrument having channeled jaws especially adapted to receive and close the clip.
摘要:
Vinylsilylalkoxy arylbenzotriazol monomers such as 2-[3'-t-butyl-5'-(3-"-dimethylvinylsilylpropoxy)-2'-hydroxy-phenyl]-5-methoxybenzotriazole are disclosed. These monomers can be incorporated in optically clear silicone polymers to form intraocular lenses, contact lenses, and the like, which have UV absorbing properties.
摘要:
Ultraviolet light absorbing compositions comprising 2-(2'-hydroxy-5'-acryloyloxyalkoxyphenyl(-2H-benzotrizoles, and copolymers thereof with one or more other monomers copolyermizable therewith, particularly acrylic monomers, are useful in the manufacture of ocular devices, particularly intraocular lenses and contact lenses.
