Patent

CA 2721100

An assembly (100) for wetting a medical device (101) is provided. The assembly has a package (110) for a medical device (such as a catheter) and a compartment (155) for a fluid medium (such as a saline solution containing an antimicrobial agent). This assembly includes a device (160) for removing covering parts of a barrier-film. The covering parts (171,172) of the barrier film are used to cover the inlet (130) to the package and the outlet (149) from the compartment prior to use. The barrier-film (170) also includes a pulling part (373,573) which is used for pulling at the covering parts. The film-removal device uses different mechanisms to remove the film. For example a toothing mechanism (163,164), a swivel arm (361), a wedge-mechanism (561) and a screw-and-spindle mechanism (761) can be used. All mechanisms are able to transfer a movement in one direction for connecting the inlet with the outlet into a pulling force in a transverse direction for removing the covering parts of the barrier film. This way the user only needs to apply pressure in one direction to get the assembly ready for use. The mechanisms may all include a reel, which is used for winding the pulling part of the barrier film around it. Furthermore, a method for wetting a medical device and a method for manufacturing an assembly are provided.

La présente invention concerne un ensemble (100) destiné à humidifier un dispositif médical (101). Lensemble comprend un conditionnement (110) pour dispositif médical (tel quun cathéter) et un compartiment (155) pour milieu fluide (tel quune solution saline contenant un agent antimicrobien). Cet ensemble comporte un dispositif (160) destiné à retirer les parties couvrantes dun film barrière. Les parties couvrantes (171, 172) du film barrière servent à couvrir lorifice dentrée (130) du conditionnement et lorifice de sortie (149) du compartiment avant utilisation. Le film barrière (170) comprend aussi une partie traction (373, 573) qui sert à tirer les parties couvrantes. Le dispositif de retrait de film utilise différents mécanismes afin de retirer le film. Il est possible dutiliser, par exemple, un mécanisme de dentelure (163, 164), un bras pivotant (361), un mécanisme de calage (561) ainsi quun mécanisme à broche et à vis (761). Tous les mécanismes sont capables de transférer un mouvement dans une direction pour relier les orifices dentrée et de sortie en vue dexercer une force de traction suivant une direction transversale afin de retirer les parties couvrantes du film barrière. Ainsi, lutilisateur na plus quà exercer une pression dans une direction pour que l'ensemble soit prêt à lemploi. Les mécanismes peuvent tous comprendre une bobine sur laquelle peut être enroulée la partie traction du film barrière. De plus, linvention porte aussi sur un dispositif médical et un procédé de fabrication dun tel ensemble.
