摘要:
A medicament delivery device, which comprises a driving mechanism and a housing (1) having a reservoir (2), which is at least partly filled with a substance and which is sealed at least on one side with a flexible wall (21). The driving mechanism is adapted to press a piston (23) against the flexible wall (21) thereby releasing the substance from the reservoir (2) through an opening (25) in the reservoir (2). This provides for a safe and reliable medicament delivery device.
摘要:
The invention relates to an electronic pill (102) for delivery of a medication (104) inside a mammal. The electronic pill (102) comprises a reservoir (106) for releasing the medication (104) in response to a predefined level of pressure. Furthermore a primary elastic element (108) is comprised for applying said predefined level of pressure to the reservoir (106) via a piston (110) upon release from the piston (110) of its constrained position. The piston (110) in its turn, when in constrained position, induces a predefined level of stress in the primary elastic element (108) by accordingly deforming it. The electronic pill (102) comprises a mechanism (114) for changing, upon actuation, from a constraining configuration in which the piston (110) is maintained at its constrained position to a releasing configuration in which the piston (110) is released. The mechanism (112) limits the displacement of the piston (110) during changing between said configurations to a level which is substantially smaller than the deformation introduced in the primary elastic element (108).

An electronic capsule (100) is provided. The capsule (100) has a discrete drive element (300) comprising: a housing (109), electronics for making the electronic capsule (100) operable, a pumping mechanism (115) for dosing and displacing a substance, a power source (105) for powering the electronic capsule (100) and enabling the electronics and the pumping mechanism (115) to operate, and a locking mechanism (130); and a discrete payload element (200) comprising: a housing (109), a reservoir (210) for storing the substance, one or more openings (250) in the housing (109) for releasing the substance from the reservoir (210) and a locking mechanism (230) for engaging the drive element locking mechanism (130). Engagement of the drive element locking mechanism (130) with the payload element locking mechanism (230) secures the drive element (300) to the payload element (200), thereby making the electronic capsule (100) operable and specific.

摘要:
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.
摘要:
An ingestible electronic capsule (100) for introduction into the bodily lumen comprises a circuit board with at least one electronic component (4, 5, 7, 8, 9, 11, 12, 13, 14). The circuit board is formed from a flex foil (10), thereby reducing the number of components and improving the robustness and reliability of the ingestible electronic capsule (100).
摘要:
A medicine reservoir (10) is provided for use with a drug delivery device (50). The medicine reservoir (10) is arranged for comprising a drug (13) and comprises a dispensing hole (15) for dispensing the drug (13) into an environment of the drug delivery device (50). The medicine reservoir (10) further comprises a deformable plug (14) which plug (14) is removable by pressure caused by a dispensing action of the drug delivery device (50).
摘要:
The invention relates to a swallowable medication capsule capable 200 of dispensing fluid medicine stored in a medication compartment 211 through a valveless exit holt 207. A vent hole 206 enables ventilation of an actuator cavity 212 which houses an actuator used for displacing a surface 205 which separates the medication cavity 211 and the actuator cavity 212. By locating the vent and exit holes close to each other so that contact with contracting parts of the gastrointestinal tract and the exterior surface 221 is not able to prohibit a pressure passageway between the vent and exit holes, creation of a pressure difference of pressures in the medication and actuator cavity is prohibited.
摘要:
A drug delivery device (50) is provided comprising a drug reservoir (10) and a piston (11). The drug reservoir (10) is provided for comprising a drug and comprises a flexible wall (22) and a dispensing hole (15) for dispensing the drug into an environment of the drug de delivery device (50). The piston (11) is provide for pressing against the flexible wall (22) to compress the drug reservoir (10) for pushing an amount of the drug through the dispensing hole (15). An adhesion interface (51) between a surface of the piston (11) and the flexible wall (22) prevents sliding between the surface of the piston (11) and the flexible wall (22).
