  • Patent number: 9687638
    Abstract: The invention relates to a swallowable medication capsule capable 200 of dispensing fluid medicine stored in a medication compartment 211 through a valveless exit hole 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.

  • Patent number: 9616206
    Abstract: 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.

  • Patent number: 8585878
    Abstract: An apparatus and method for electrochemical fluid analysis comprises a chamber (1202) having a depth dimension for accommodating a volume of a fluid under test, first and second electrodes (A1) disposed within the chamber and extending along the depth dimension in spaced relation with each other, and a soluble solid, such as an annealed polymer, e.g. EUDRAGIT occupying a lateral gap between the first and second electrodes. The rate of dissolution as monitored by electrochemical impedance spectroscopy (EIS) of the soluble solid within the fluid depends on the chemical concentration of a corresponding analyte present in solution in the fluid. In one embodiment a silicon-based integrated circuit device defining an upper margin includes an array of electrodes disposed along said upper margin to permit direct exposure of the electrode array to the fluid under test. The device is constructed using CMOS technology.
