Abstract

Disclosed is a dispensing system. The dispensing system includes a dispensing unit to dispense therapeutic fluid, and a validation mechanism to enable operation of the dispensing unit based, at least in part, on a determination of whether operation of the dispensing device is authorized.

Claims

1. A system for dispensing a therapeutic fluid to a body of a user, the system comprising:

a reservoir to contain the therapeutic fluid;

a cannula insertable into the body of the user, providing a fluid path between the reservoir and the user'"'"'s body;

a driving mechanism configured to engage with the reservoir to dispense the therapeutic fluid;

a processor controlling the driving mechanism;

a first ID marker for authenticating at least a portion of the system;

an ID reader for reading the first ID marker and for providing a signal to the processor; and

a power source to provide power to at least one of the driving mechanism and the processor,

wherein the processor enables one or more functions of the system based on the signal received from the ID reader, and

wherein the system includes a dispensing unit which includes the reservoir, the driving mechanism and the first ID marker,

wherein the system includes a remote control unit which includes the ID reader,

wherein both the remote control unit and the dispensing unit identify communications between each other with a specific key,

wherein the specific key is shared and set by the units via a second ID marker being read by the ID reader of the remote control unit to pair the units and once paired the remote control unit and the dispensing unit communicate only with each other and no other unit.

2. The system of claim 1, further comprising a sensor for monitoring analyte levels.

3. The system of claim 1, wherein the dispensing unit comprises at least two portions, a first portion having the first ID marker and a second portion having another ID reader.

4. The system of claim 3, wherein the first portion interacts with the second portion.

5. The system of claim 1, wherein the ID reader includes an RFID reader and the first ID marker includes an RFID tag.

6. The system of claim 1, wherein the first ID marker includes a rewriteable memory.

7. The system of claim 1, wherein the first ID marker includes a barcode and the ID reader includes a barcode reader.

8. The system of claim 1, further comprising a database storing information related to reading of the first ID marker, at least a portion of the signal received from the ID reader comprises information, and the processor compares at least some of the information received from the ID reader with at least some of the information stored in the database.

9. The system of claim 1, further comprising a disabling mechanism to disable subsequent reading of the first ID marker after a connection between at least one first portion of the system with at least one second portion of the system.

10. The system of claim 9, wherein the disabling mechanism subjects the first ID marker to an overload of electrical power.

11. The system of claim 10, wherein the disabling mechanism is induced by the ID reader.

12. The system of claim 1, wherein the first ID marker is a bar code.
