Title:
注射可能な薬物送達デバイスの投与量制御システムおよび関連の使用方法
Document Type and Number:
Japanese Patent JP7455107
Kind Code:
B2
Abstract:
The invention relates to a dose control system configured for an injectable drug delivery device. The device comprises a disk-shaped diametral single-dipole magnet (9) attachable to a rotatable dose wheel, a housing removably attachable to the proximal extremity of the drug delivery body and comprising at least a first and a second magnetic field measurement means (8). An integrated control unit (2) is connected to the magnetic field measurement means and is configured to process information received therefrom. The magnetic field measurement means are located in the housing in a displaced axial relationship relative to the longitudinal axis of the drug delivery body and the magnet. The magnet is configured to co-rotate with the dose setting wheel and the integrated control unit is configured to provide a normalized vector with regard to the displaced axial relationship of the magnetic field measurement means, said normalized vector being derived from the measured magnetic field generated by the rotation of the magnet and measured by the magnetic field measurement means. A dose setting is calculated from said normalized vector.
