KLEEFMIDDELSAMENSTELLING VOOR TOEPASSING ROND EEN CHIRURGISCHE AFVOEROPENING VOOR VLOEISTOFFEN.

摘要

Protective sealing compositions in the form of molded rings or sheets for application around surgical fluid drainage openings, which compositions comprise a gelled mixture of a water-absorbing particulate hydrocolloid gum (e.g. Karayagum) and a non-toxic liquid polyhydroxy alcohol (e.g. glycerin or propylene glycol) are provided with increased resistance to the drained fluid (viz. urine or intestinal fluids) by incorporating a small amount of colloidal silica. Fumed silica is preferred. By limiting the amount of silica added appreciable reductions in the wet tack and/or dry tack of the composition can be avoided.
