Abstract

The present disclosure relates to an activation system for a supplemental device that is attached to an existing design of a medicament delivery device, where the removal of a protective cap or other covering from the medicament delivery device pulls a blocking element from between electrical contacts to close a circuit between a battery module and a power source, thus activating the battery module. The supplemental device can further have a transmitter for communicating information about the use of the medicament delivery device to an external device, such as a smart device. Memory storage elements can also be included having unique identification data. The present disclosure also relates to a medicament delivery device having attached the supplemental device.

First claim

The invention claimed is:

1 . A system for activating a supplemental device attached to a medicament delivery device, the system comprising:
a medicament delivery device comprising:
a housing;
a medicament container positioned within the housing; and
a dose delivery outlet accessible through a terminal end of the housing,
a removable cap attached to the housing such that the dose delivery outlet is prevented from being accessible unless the cap is fully removed from the medicament delivery device; a supplemental device comprising:
a battery module attached to the housing or to the cap, wherein the battery module comprises: a battery; a contact pad; and a switch operatively connected to the battery and the contact pad, wherein a part of the switch is directly connected to the cap when the battery module is attached to the housing or where a part of the switch is directly connected to the housing when the battery module is attached to the cap; and
a communication module connectable to the battery module or included as part of the battery module, and configured to transmit data to an external device, wherein the data comprises information directly related to a status of the switch, wherein the switch is initially in a first state where the communication module is prevented to receive power from the battery and where movement of the cap relative to the housing changes the switch to a second state where the battery provides power to the communication module,
wherein the switch further comprises a biasing component that exerts a force that biases the contact pad towards a contact surface operatively associated with the battery, and a strip of material operatively connected with the battery or contact pad, and
wherein the strip of material is configured to allow the cap to be separated first from the housing before being removed from the battery module.

2 . The system of claim 1 , wherein the switch is configured to be in the first state only once.

3 . The system of claim 1 , wherein the switch is prevented to transform from the second state back to the first state.

4 . The system of claim 1 , wherein removal of the strip of material from the battery module starts the data transmission by the communication module.

5 . The system of claim 4 , wherein the strip of material comprises insulating material such that the strip prevents electricity conduction.

6 . The system of claim 5 , wherein the part of the switch comprises the strip material and is connected to an outside or inside surface of the cap or of the housing.

7 . The system of claim 1 , wherein the attachment of the battery module and of the communication module are permanent such that the housing and the battery module are disposable and are prevented to be separated from each other without destroying the housing or the modules.

8 . The system of claim 1 , wherein the battery module or the communication module comprises one or more sensors configured to detect a motion of at least one of the components of the medicament delivery device.

9 . The system of claim 1 , wherein the system further comprises a sensor module connectable to any other module and wherein said sensor module comprises one or more sensors configured to detect a motion of at least one of the components of the medicament delivery device.

10 . The system of claim 9 , wherein any of the modules is removable from the housing and is reusable.

11 . The system according to claim 1 , wherein the battery module or the communication module comprises a recorder configured to obtain and store data information about the medicament delivery device.

12 . The system of claim 11 , wherein the data transmission by the communication module starts when the recorder receives power from the battery.

13 . The system of claim 1 , wherein the system further comprises a logging module connectable to any other module or included as part of any other module, and wherein the logging module is configured to start tracking motion of the medicament delivery device when the cap is removed.

14 . The system of claim 1 , wherein the system further comprises a memory module connectable to any other module or included as part of any other module, and wherein the memory module is configured to store the data and the communication module is configured to transmit the data wirelessly to the external device.

15 . A system comprising a supplemental device attached to a medicament delivery device, wherein the medicament delivery device comprises:
a housing having a proximal end and a distal end; and a removable cap attached to the proximal end of the housing that prevents user access to an outlet of a medicament container when positioned within the housing unless the cap is fully removed from the medicament delivery device, and wherein the supplemental device comprises: a battery module attached to the housing or to the cap, where the battery module comprises: a battery; a contact pad; a switch operatively connected to the battery and the contact pad, where a part of the switch is directly connected to the cap when the battery module is attached to the housing or where a part of the switch is directly connected to the housing when the battery module is attached to the cap; and a communication module connectable to the battery module or included as part of the battery module, and configured to transmit data to an external device, where the data comprises information directly related to a status of the switch, wherein the switch is initially in a first state where the communication module is prevented to receive power from the battery and where movement of the cap relative to the housing changes the switch to a second state where the battery provides power to the communication module, wherein the switch is prevented from transforming from the second state back to the first state, and wherein the switch includes a strip of material operatively connected with the switch, the strip of material being configured to allow the cap to be separated first from the housing before being removed from the battery module.

16 . The system of claim 15 , wherein removal of the cap from the housing causes movement of the strip of material which electrically connects the battery to the communication module.

17 . The system of claim 16 , wherein the strip of material comprises an insulating material that prevents electricity conduction between the contact pad and the battery.

18 . The system of claim 16 , wherein the part of the switch comprises the strip material and is connected to an outside or inside surface of the cap or of the housing.

19 . The system of claim 16 , wherein the switch further comprises a biasing component that exerts a force that biases the contact pad towards a contact surface operatively associated with the battery.
