Electronic pill comprising a plurality of medicine reservoirs
View Patent ↗Electronic pill ( 1, 11, 21 ) comprising a plurality of medicine reservoirs ( 2, 12, 22 ), each of the reservoirs comprising a discharge opening ( 3, 13, 23 ) covered by a removable cover ( 6, 16, 26 ). The pill comprises at least one actuator responsive to control circuitry for removing the cover from the discharge opening ( 3, 13, 23 ). The actuator can for example be a spring loaded piston ( 4 ) breaking a foil cover when dispensing the medicament. 5 Alternatively, the cover can be a rotatable disk ( 16 ) or cylinder ( 26 ) with an opening ( 17, 27 ) which can be brought in line with the discharge opening of a reservoir under the action of the actuator.
1. An electronic pill comprising:
a plurality of medicine reservoirs, each of the plurality of medicine reservoirs comprising a discharge opening covered by a removable cover;
a plurality of mechanical actuators, each of the plurality of mechanical actuators corresponding to each of the plurality of medicine reservoirs, each of the plurality of mechanical actuators configured to increase a pressure in the corresponding medicine reservoir to force contents contained in the corresponding medicine reservoir out of the respective medicine reservoir, through the respective discharge opening, wherein the removable cover comprises a rotatable member with an opening which can selectively be brought in line with the discharge opening of each of the plurality of medicine reservoirs under the action of an actuator.
2. The electronic pill according to claim 1 wherein the removable cover further comprises a film removable by rotation of the rotatable member.
3. The electronic pill according to claim 1 wherein the actuator is a spiral spring element acting on the rotatable member to move it by discrete steps to bring the opening in the rotatable member in line with a single reservoir with each subsequent discrete step.
4. The electronic pill according to claim 1 wherein the rotatable member comprises a disk having an opening which can be brought in line with the respective discharge opening of each of the plurality of medicine reservoirs.
5. The electronic pill according to claim 1 wherein each of the plurality of mechanical actuators comprises a spring loadable piston in at least a part of the respective medicine reservoir.
6. The electronic pill according to claim 1 wherein each of the plurality of mechanical actuators comprises a memory alloy in at least a part of respective medicine reservoir.
7. The electronic pill according to claim 1 wherein each of the plurality of mechanical actuators comprises a fuse breakable under the action of an applied electric current in at least a part of respective medicine reservoir.
8. The electronic pill according to claim 1 wherein the plurality of medicine reservoirs are longitudinal reservoirs with parallel longitudinal axes and having a cross section corresponding to the discharge opening.
9. The electronic pill according to claim 1 wherein the plurality of medicine reservoirs form adjacent radial cylinder sections.
10. The electronic pill according to claim 3 wherein the rotatable member comprises a disk having an opening which can be brought in line with the respective discharge opening of each of the plurality of medicine reservoirs.
11. An electronic pill comprising:
a plurality of medicine reservoirs, each of the plurality of medicine reservoirs comprising a discharge opening;
a cover comprising a rotatable member with an opening, the cover being movable by an actuator to selectively place the opening in line with the discharge opening of each of the plurality of medicine reservoirs.
12. The electronic pill according to claim 11 wherein the actuator is a spiral spring element acting on the rotatable member to move it by discrete steps to bring the opening in the rotatable member in line with a single reservoir with each subsequent discrete step.
13. The electronic pill according to claim 12 wherein the rotatable member comprises a disk having an opening which can be brought in line with the respective discharge opening of each of the plurality of medicine reservoirs.
14. The electronic pill according to claim 11 wherein the rotatable member comprises a cylindrical wall enveloping the reservoirs and having a slot-shaped opening which can be brought in line with the respective discharge opening of each of the plurality of medicine reservoirs.
15. The electronic pill according to claim 11 wherein the rotatable member comprises a disk having an opening which can be brought in line with the respective discharge opening of each of the plurality of medicine reservoirs.
