Reservoir module for a drug delivery system
First Claim
1. A medicament reservoir module for attachment to a pumping unit containing pumping means and control mechanism for a drug delivery system, said reservoir module, comprising:
- a housing adapted for releasable connection to said pumping unit and for supporting a vial of liquid medicament intended for use in said drug delivery system, said vial having length and being closed at one end by a base and having an open second end and a penetratable vial stopper movable as a piston in said vial;
an adaptor, including;
a collar having first means for attachment to said vial stopper and having second means for attachment to a medicament delivery tube;
a hollow needle mounted to said collar for penetrating said stopper when a vial is connected to said adaptor by said first means for attachment;
a flexible medicament delivery tube means having a first end connected to said second attachment means for movement with said adaptor, and a second end portion releasably fixed in relation to said housing for operative pumping engagement with said pumping means when said pumping unit is connected to said housing, said tube means being resilient and having clack between said second end portion thereof and said adaptor, permitting said adaptor to move a distance at least equal to the length of said vial.

Abstract
A medicament reservoir module for attachment to a pumping and control module includes a conventional medicament vial closed at one end by a penetrable stopper, which is inserted to operate as a piston in the vial. A hollow needle, attached to an adaptor that releasibly connects to the stopper, pierces the stopper and provides a medicament flow path via a slack length of flexible tubing from the vial to a peristaltic pump in the pumping and control module. A housing supports the vial, encloses the adaptor, hollow needle, and slack tubing, and releasibly connects to the pumping and control module. Thereby, a detachable reservoir module is provided, permitting quick and reliable resupply of medicament directly from filled standard vials.

11. A medicament reservoir module for attachment to a pumping unit containing pumping means and control mechanism for a drug delivery system, said reservoir module, comprising:
-
a first housing for supporting a vial of liquid medicament intended for use in said drug delivery system, said vial having length and being closed at one end of a base and having an open second end and a penetratable stopper mounted as a piston in said vial; an adaptor including;
a collar having first means for attachment to said vial stopper, and having second means for attachment to a medicament delivery tube;a hollow needle mounted to said collar for penetrating said stopper when a vial is connected to said adaptor by said first means for attachment; a second housing adapted for releasable connection at a first interface with said pumping unit and at a second interface with said first housing; a flexible medicament delivery tube means in said second housing, said tube means having a first end connected to said second attachment means for movement with said adaptor, and a second portion releasably fixed in relation to said second housing for operative pumping engagement with said pumping means at said first interface when said pumping unit is connected to said second housing, said tube means being resilient and having slack between said second end portion thereof and said adaptor, permitting said adaptor to move a distance at least equal to the length of said vial. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
