Title
(EN) METHOD OF STERILIZING PREFILLED SYRINGE MEDICINES
(FR) PROCEDE DE STERILISATION DE MEDICAMENTS DANS DES SERINGUES PRE-REMPLIES
Abstract
(EN)
The invention provides a method of sterilizing a chemical and an injector in a prefilled syringe and keeping them in sterilized condition, said method comprising mounting a liquid leakage preventive cap (1) on a tip end of an injector (2) in a prefilled syringe, filled with a chemical and mounting a sliding plug (3) in an opening at a rear end of the injector to prevent liquid leakage of the prefilled syringe, securing the prefilled syringe, which mounts thereto the liquid leakage preventive cap (1) and the sliding plug (3), by means of a securing container (6), sealing the securing container (6), to which the prefilled syringe (2) is fixed, by means of a poromeric and bacteria impermeable nonwoven paper or fabric to sterilize a chemical (5) in the prefilled syringe (2), the prefilled syringe (2) and the securing container at the same time. The securing container (6) is enclosed by a bag-shaped nonwoven paper or fabric (7). Alternatively, the securing container (6) may have an opening, and the opening may be sealed by the nonwoven paper or fabric (11). According to the invention, it is possible to manufacture a prefilled syringe kit readily at low cost in a sterilized manner and keep the sterilized condition.
(FR)
Procédé permettant de stériliser des substances chimiques et un dispositif d'injection contenus dans une seringue pré-remplie et de maintenir ces éléments à l'état stérile. Ce procédé consiste à monter un capuchon de protection contre les fuites de liquide (1) sur l'extrémité antérieur d'un dispositif d'injection (2) d'une seringue pré-remplie, remplie d'une substance chimique, puis à monter un bouchon coulissant (3) dans l'ouverture située à l'extrémité postérieure du dispositif d'injection, pour interdire la fuite de liquide hors de la seringue pré-remplie, à fixer cette seringue comprenant désormais le capuchon (1) et le bouchon coulissant (3) dans un contenant d'immobilisation (6), à enfermer ce contenant d'immobilisation (6) dans lequel la seringue pré-remplie est fixée, à l'aide d'un papier ou d'une étoffe non tissé poromérique imperméable aux bactéries pour stériliser la substance chimique (5) contenue dans la seringue (2), la seringue elle-même (2) et le contenant au cours d'une seule et même opération. Le contenant (6) est enfermé dans un papier ou dans une étoffe (7) non tissé en forme de sac. Selon une variante, le contenant (6) peut comporter une ouverture pouvant elle-même être obturée par du papier ou une étoffe non tissé (11). Grâce à ce procédé, il est possible de réaliser pour un coût modéré une seringue pré-remplie en kit dans des conditions stériles, et de préserver cet état stérile.
