Patent CA-2685583-A1 (CA)
Inventor: SZYMANSKI MAREK
IPC: B67D99/00
Filed: 2008-04-21
Abstract: This disclosure relates to a liquid dispensing apparatus for dispensing a liquid from a flexible bag. The apparatus has a support for supporting the flexible bag in use and a mounting adapted for receiving a proximal portion of the flexible bag, for progressive movement relative to the support toward s an outlet located at a distal portion of the flexible bag. As the flexible bag is progressively wound up, liquid is squeezed from the proximal portion to the distal portion to dispense liquid from the outlet in a controlled ma nner in use. This allows desired and precise dosage portions of liquid to be squeezed from the bag and direct dosing from the flexible bag amongst other advantages.

Inventor: BECKER KIM
IPC: A61M25/00
Filed: 2009-05-20
Abstract: 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.
