Medicament injection device with lockout feature
View Patent ↗A lockout feature for an injection device includes a time lock that prevents a user from administering a dose of medicament prior to a pre-determined time interval. The lockout feature can interface with a cap and dose setting module to prevent removal of the cap or it can work to disable the dose delivery module to prevent an injection from occurring.
1. A safety injection system comprising,
a multi-dose delivery module having a distal end for accepting a needle and a proximal end for setting a dose;
a removable cap configured to cover the distal end of the dose delivery module; and
a time lock operatively connected to the cap and the multi-dose delivery module
where the time lock is configured such that when the cap is placed on the distal end of the dose delivery module after a first injection,
the time lock prevents a user from removing the cap to perform a second injection unless predetermined conditions exist.
2. The safety injection system according to claim 1 where the time lock is time controlled.
3. The safety injection system according to claim 1 where the time lock is settable.
4. The safety injection system according to claim 1 where the time lock is opened and closed by a controller.
5. The safety injection system of claim 4 where the controller is part of the multi-dose delivery module or part of the cap.
6. The safety injection system according to claim 5 where the controller is configured to receive a signal from an electronic circuit.
7. The safety injection system of claim 6 where the signal can be wired or wireless.
8. The safety injection system according to claim 6 where the electronic circuit is part of cap, the multi-dose delivery module, a personal computer, a remote computer, a remote server, or a combination of same.
9. The safety injection system according to claim 4 where the controller is programmable.
10. The safety injection system according to claim 4 further comprising an alert sub-system in communication with the controller.
11. The safety injection system of claim 10 where the alert sub-system is configured to provide a user of the safety injection device with an audible, visual or tactical or combination audible/visible, audible/tactical or visual/tactical signal.
12. The safety injection system according to claim 4 where the controller is in communication with an analytical device that is configured to monitor or test a physiological characteristic of a user of the safety injection system.
13. The safety injection system according to claim 7 where the lock has an override feature to allow a user to unlock the device after inputting one or more predetermined signals into a controller.
14. The safety injection system according claim 1 , wherein the safety injection system is configured to permanently close the time lock after a set or settable time.
15. The safety injection system according to claim 1 with an energy supply for actuating the time lock, wherein the safety injection system is configured to open the time lock when the energy left in the energy supply underruns a set threshold.
