Title: Endoscope instrument having reduced backlash during insertion
Inventor: SMITH KEVIN W
IPC: A61B1/018
Filed: 2000-10-12
Granted: 2009-12-22
Abstract: An endoscopic instrument has a portion having an outer surface with a non-circular cross-sectional shape. The non-circular cross-sectional shape may be provided to the instru-ment by providing peripheral projections or fins along the length of the portion or by providing the periphery of the portion with a polygonal shape. Where fins are used, the fins are preferably quite small and only have a minimal effect on the fluid flow cross sec-tional area between the interior of the working channel and the en-doscopic instrument. The resulting instrument has significantly re-duced backlash while maintaining adequate fluid flow in the work-ing channel. According to a second embodiment of the invention, a portion of the interior of the working channel of the endoscope has an interior surface having a non-circular cross-sectional shape by the inclusion of a plurality of radially spaced and inwardly directed ribs or by being polygonally shaped. The resulting endoscope re-duces the backlash of an endoscopic instrument inserted therein while maintaining adequate fluid flow in the working channel.

Abstract: L'invention concerne des matières avec des niveaux élevés de matière insaponifiable résultant en des hydrolysats avec des propriétés uniques. On a découvert que l'application d'un procédé d'hydrolyse à des matières, en particulier, des matières avec un niveau élevé d'insaponifiables (à savoir au moins 6 % du poids total de la matière) produit un produit avec des propriétés sensiblement différentes des produits résultant de la saponification classique de matières avec moins de 6 % en poids d'insaponifiables. Les hydrolysats résultant résistent à la fois au retrait physique et aqueux de la peau et des cheveux, présentent une propriété tensioactive très particulière, et ne sont pas des agents moussants avec de l'eau. Les hydrolysats peuvent selon la présente invention être utilisés afin d'améliorer les performances des produits cosmétiques et pharmaceutiques. Ces hydrolysats sont des agents bioactifs et des excipients naturels alternatifs dans des applications topiques de matières, en particulier, dans l'application de matières sur la peau ou les cheveux de patients, et fournissent un support significatif pour les matières supportées.

Abstract: The invention relates to chemical and pharmaceutical industry and medicine, namely, to the method of obtaining immunotropic, apyrogenic, non-toxic, non-resistant preparations possessing high antiviral activity towards RNA- and DNA-viruses and under multiple infection, these preparations being obtained from animal material (soft roe of sturgeon fish or salmon fish, calf thymus, chicken blood, pig spleen). To obtain immunotropic antiviral pharmaceutical preparations possessing high therapeutic activity towards RNA-and DNA-viruses defatted soft roe of sturgeon fish or salmon fish, or calf thymus, or chicken blood, or pig spleen are ground and homogenized in citrate-salt solution. Homogenate is incubated in presence of detergent; sodium chloride concentrated solution is added to the reaction mix under continuous stirring and high temperature. The reaction mix is cooled, sonicated under standardized conditions, then it is treated with sorbent and detergent, filtrated and concentrated. DNA-Na white amorphous precipitate is isolated from concentrate with ethanol, DNA-Na molecular mass is 270-500 kD, hyperchromic effect is not lower than 37%, protein content is less than 1%. DNA-Na precipitate is dried and dissolved in standardized transition metal solution to make 1.5% solution with hyperchromic effect not lower than 10%, the solution is sterilized by baro-membrane method and poured under sterile conditions in therapeutic doses (75 mg). Water-soluble salts of transition metals Zn, Co, Fe, Mn, Sb are used to obtain immunotropic antiviral preparations. DNA-Na to metal ratio in the preparation is within range 50-500:1-2. Immunotropic non-resistant apyrogenic preparations possess antiviral activity towards RNA- and DNA-viruses and their combined presence.
