DRUG DELIVERY SYSTEM WITH WIRELESS MONITOR
First Claim
1. A drug delivery system for delivering a drug to the body of a user, the system comprising:
- (a) a drug delivery device including;
(i) a housing;
(ii) a reservoir containing a quantity of the drug, said reservoir being located at least partially within said housing;
(iii) an infusion arrangement for delivering the drug into the body of the user;
(iv) a flow controller for controlling a flow of the drug from the reservoir to the infusion arrangement; and
(v) a first communication device associated with said flow controller and including at least a transmitter, said first communication device transmitting wirelessly information indicative of a current state of operation of said flow controller; and
(b) a remote unit including;
(i) a display;
(ii) a plurality of user input controls;
(iii) a remote unit controller associated with said display and said user input controls; and
(iv) a second communication device associated with said remote unit controller and including at least a receiver, said second communication device receiving said wirelessly transmitted information and supplying said information to said remote unit controller for display on said display,wherein said remote unit is configured to receive user input via said user input controls to define a required change in operation of said flow controller, and wherein said drug delivery device is configured to require tactile intervention by the user prior to said required change in operation being implemented.

Abstract
A portable drug delivery system (10) includes a remote unit (14) which serves as a wireless monitor for a drug delivery device (12). Programming of the drug delivery device (12) can be achieved by use of the remote unit (14), but requires tactile intervention by the user with the drug delivery device, thereby avoiding inadvertent or unauthorized changes to the drug delivery settings via the wireless unit. Also disclosed are configurations for receiving and retaining a drug cartridge (42) within a disposable unit (40) of the drug delivery device, and a kit providing user-selectable form factor for the infusion set used with the drug delivery device, allowing the user to select either an integrated infusion set (112) or an external infusion (106) set for each session of use.

7. A method for operating a drug delivery system for delivering a drug to the body of a user, the method comprising the steps of:
-
(a) providing a drug delivery device including a reservoir containing a quantity of the drug and a flow controller for controlling a flow of the drug from the reservoir to the body of the user; (b) providing a remote unit including a display and a plurality of user input controls; (c) deploying the drug delivery device to deliver the drug to the body of the user in a first defined manner; (d) during operation of the drug delivery device, transmitting wirelessly from the drug delivery device to the remote unit information indicative of a current state of operation of the drug delivery device for display on the display; (e) inputting to the remote unit via the user input controls a required change in operation of the drug delivery device; (f) transferring to the drug delivery device data indicative of the required change in operation; and (g) changing the operation of the drug delivery device in accordance with said data, wherein at least one of said transferring and said changing requires tactile intervention by the user with the drug delivery device. - View Dependent Claims (8, 9, 10, 11, 12)

13. A drug delivery device for delivering a drug to the body of a user, the device comprising a disposable unit for receiving a cartridge containing a drug to be delivered, said disposable unit comprising:
-
(a) a channel for receiving the cartridge containing the drug to be delivered, said channel having an opening and a direction of extension; (b) a loading spring deployed within said channel for applying a loading force on the cartridge when inserted within said channel, said loading force acting along said direction of extension towards said opening; and (c) a retention configuration deployed near said opening, said retention configuration including a plurality of rearwardly directed resilient teeth configured; (i) to retain said loading spring in a pre-compressed state within said channel prior to insertion of the cartridge, (ii) to flex outwards to allow insertion of the cartridge between said teeth, and (iii) to assume a retaining position engaging a recessed portion of the cartridge when the cartridge is fully inserted. - View Dependent Claims (14, 15, 16)
