Device for completely immersing an endoscopy capsule floating on a surface of a liquid in a patient into the liquid by separating the endoscopy capsule from the surface of the liquid, having - an endoscopy capsule comprising a fixedly integrated magnetic element with a magnetic dipole moment ( m), - a solenoid system for generating a magnetic field and/or a magnetic gradient field for magnetic guidance of the endoscopy capsule, - a control unit with technical hardware and software means for controlling the supply of current to individual coils of the solenoid system, wherein - the technical software means in the control unit contain software for controlling the supply of current to the individual coils of the solenoid system, which software controls the solenoid system such that to separate the endoscopy capsule from the surface of the liquid the solenoid system for generating the magnetic field and/or the magnetic gradient field for magnetic guidance of the endoscopy capsule generates a brief force curve (F_mag(t)) with at least one force pulse (F_mag1, F_mag2, F_mag3) onto the endoscopy capsule, the direction of the force pulse (F_mag1, F_mag2, F_mag3) being substantially perpendicular to the surface of the liquid, wherein the brief force curve (F_mag(t)) is calculated in advance, depending on parameters characterising the endoscopy capsule, in particular the geometry, surface characteristics and alignment of the capsule longitudinal axis relative to the water surface, and parameters characterising the liquid, in particular temperature, chemical composition, clarity and viscosity, such that after the brief force curve (F_mag(t)) has been generated the endoscopy capsule - is completely immersed and - is located just below the surface of the liquid, and the brief force curve (F_mag(t)) is automatically generated after being triggered by an operator. - an endoscopy capsule comprising a fixedly integrated magnetic element with a magnetic dipole moment ( m), - a solenoid system for generating a magnetic field and/or a magnetic gradient field for magnetic guidance of the endoscopy capsule, - a control unit with technical hardware and software means for controlling the supply of current to individual coils of the solenoid system, wherein - the technical software means in the control unit contain software for controlling the supply of current to the individual coils of the solenoid system, which software controls the solenoid system such that to separate the endoscopy capsule from the surface of the liquid the solenoid system for generating the magnetic field and/or the magnetic gradient field for magnetic guidance of the endoscopy capsule generates a brief force curve (F_mag(t)) with at least one force pulse (F_mag1, F_mag2, F_mag3) onto the endoscopy capsule, the direction of the force pulse (F_mag1, F_mag2, F_mag3) being substantially perpendicular to the surface of the liquid, wherein the brief force curve (F_mag(t)) is calculated in advance, depending on parameters characterising the endoscopy capsule, in particular the geometry, surface characteristics and alignment of the capsule longitudinal axis relative to the water surface, and parameters characterising the liquid, in particular temperature, chemical composition, clarity and viscosity, such that after the brief force curve (F_mag(t)) has been generated the endoscopy capsule - is completely immersed and - is located just below the surface of the liquid, and the brief force curve (F_mag(t)) is automatically generated after being triggered by an operator.
