Needle storage magazine with status indication
A magazine ( 18 ) that stores a plurality of needles ( 56 ) configured to engage a medication pen ( 2 ) for medication delivery, the magazine ( 18 ) comprising a magazine housing ( 20 ) enclosing a removable array ( 26 ) having a plurality of hub chambers ( 22 ) each enclosing one of a plurality of needle hubs ( 50 ), a connector ( 28 ) in each of the plurality of huh chambers ( 22 ), each connector ( 28 ) engages one of the plurality of needle hubs ( 50 ), a plurality of peel tabs ( 30 ) each sealing one of the plurality of hub chambers ( 22 ), and an electronic indicator ( 62 ) to identify a status of the plurality of needle hubs ( 50 ), wherein the electronic indicator ( 62 ) identifies how many of the plurality of needle hubs ( 50 ) are unused.
1. A magazine that stores a plurality of needles configured to engage a medication pen for medication delivery, the magazine comprising:
a magazine housing enclosing
a removable array having a plurality of hub chambers each enclosing one of a plurality of needle hubs;
a connector in each of the plurality of hub chambers, each connector engaging one of the plurality of needle hubs; and
an inertial measurement unit that detects vibration, rotational movement or other gesture movement experienced by the magazine that exceeds a threshold amount.
2. The magazine of claim 1 , wherein the inertial measurement unit comprises an accelerometer.
3. The magazine of claim 1 , wherein the inertial measurement unit comprises a gyroscope.
4. The magazine of claim 1 , wherein the inertial measurement unit triggers operation of a circuit board of the magazine when a predetermined vibration value is exceeded.
5. The magazine of claim 1 , wherein the inertial measurement unit is calibrated to initiate operation of the magazine.
6. The magazine of claim 1 , wherein the inertial measurement unit activates a controller on a circuit board of the magazine from a sleep state and activates peripherals of the circuit board.
7. The magazine of claim 1 , wherein the inertial measurement unit is configured to detect vibration, rotational movement or other gesture movement generated by snapping a used needle hub onto the connector of the magazine array when the used needle hub is returned to the magazine housing.
8. The magazine of claim 1 , wherein the inertial measurement unit is configured to detect vibration, rotational movement or other gesture movement generated by an adapter snapping onto a needle hub prior to removing the needle hub from the connector of the magazine array for medication delivery.
9. A magazine that stores a plurality of needles configured to engage a medication pen for medication delivery, the magazine comprising:
a magazine housing enclosing
a first removable array and a second removable array, each (1) linearly arranged and (2) having a plurality of hub chambers each enclosing one of a plurality of needle hubs;
a connector in each of the plurality of hub chambers, each connector engaging one of the plurality of needle hubs; and
an electronic display indicating at least one of a battery level, a use status, a current condition, and a number of needle hubs; wherein
the electronic display is disposed between the first removable array and the second removable array.
10. The magazine of claim 9 , wherein
when the first removable array is removed from the magazine housing, the electronic display indicates a reduced number of needle hubs.
11. The magazine of claim 9 , wherein the use status comprises a time when a most recent needle hub of the plurality of needle hubs was removed from the magazine housing.
12. The magazine of claim 9 , wherein the current conditions comprises a current date or time.
13. The magazine of claim 9 , wherein the electronic display identifies how many of the plurality of needle hubs are unused.
14. The magazine of claim 9 , wherein the electronic display identifies a number of the plurality of needle hubs that are in the removable array.
15. The magazine of claim 9 , further comprising a controller that determines a projected replacement time of the magazine.
16. The magazine of claim 15 , wherein the projected replacement time is displayed on the electronic display.
17. The magazine of claim 9 , further comprising a controller that determines a projected replacement time of the removable array.
18. The magazine of claim 17 , wherein the projected replacement time is displayed on the electronic display.
