Abstract
An information carrier reader assembly is presented having a first antenna, a second antenna electrically connected to the first antenna, the first antenna attached to a first area of a medicament delivery device, where the medicament delivery device has an information carrier having a fourth antenna wherein the first antenna is positioned so as to enable transmission between the fourth and the first antenna. The information carrier reader assembly further has an information reader provided with an third antenna and being operably arranged to a second area of the medicament delivery device, wherein the second antenna is attached to the second area of the medicament delivery device, enabling a transmission between the second antenna and the third antenna.
Core Innovation
The invention relates to an information carrier reader assembly for a medicament delivery device, where the medicament delivery device comprises an information carrier comprising a fourth antenna. A first antenna is attached to a first area of the medicament delivery device and positioned to enable transmission between the fourth antenna and the first antenna. An information reader is provided with a third antenna and operably arranged to a second area of the medicament delivery device.
A second antenna is attached to the second area of the medicament delivery device to enable transmission between the second antenna and the third antenna. The first antenna is positioned adjacent a proximal end, and the second antenna is positioned adjacent a distal end. The first antenna, second antenna, third antenna, and fourth antenna are spaced a longitudinal distance along a length of the medicament delivery device apart from one another and enclosed inside the medicament delivery device.
The information carrier reader assembly is arranged in a separate unit releasably attachable to the medicament delivery device. The third antenna of the information reader is configured to read the second antenna when the separate unit is connected to the medicament delivery device. Metal coil antennas are interconnected via conductive conduits, and in variants the antenna parts are disposable while other parts are reusable, with example embodiments for syringes and motor-driven medicament delivery devices including a cassette and main body interface.
Claims Coverage
The document provides two independent claims, with inventive features centered on two spatially separated antennas within the medicament delivery device and a releasably attachable reader unit that reads a second antenna via a third antenna.
Two spatially positioned antennas enabling transmission across proximal-to-distal areas
The first antenna is attached to a first area of a medicament delivery device that comprises an information carrier comprising a fourth antenna, and the first antenna is positioned so as to enable transmission between the fourth and the first antenna; an information reader provided with a third antenna is operably arranged to a second area of the medicament delivery device, and the second antenna is attached to the second area of the medicament delivery device to enable a transmission between the second antenna and the third antenna.
Proximal and distal placement with longitudinal spacing and enclosure
The first antenna is positioned adjacent a proximal end of the medicament delivery device, the second antenna positioned adjacent a distal end of the medicament delivery device, and the first antenna, second antenna, third antenna, and fourth antenna are spaced a longitudinal distance along a length of the medicament delivery device apart from one another between the proximal end and the distal end of the medicament delivery device, with the first antenna, second antenna, third antenna, and fourth antenna enclosed inside the medicament delivery device.
Releasably attachable separate unit where the third antenna reads the second antenna
The information carrier reader assembly is arranged in a separate unit releasably attachable to the medicament delivery device, wherein the third antenna of the information reader is configured to read the second antenna when the separate unit is connected to the medicament delivery device.
Medicament delivery device with proximal antenna reading an information carrier in a medicament container
A medicament delivery device comprising a first antenna attached to a first part of the medicament delivery device adjacent a proximal end; a second antenna electrically connected to the first antenna and attached to a second part adjacent a distal end, wherein the first part is arranged to accommodate a medicament container that comprises an information carrier readable by the first antenna; and an information carrier reader assembly operably arranged to the second part, configured to communicate with the second antenna.
Across the independent claims, the core coverage is for a medicament delivery device having first and second antennas positioned at proximal and distal ends with longitudinal spacing, enclosed inside the device, and an information carrier reader assembly implemented as a separate releasably attachable unit in which a third antenna reads the second antenna when connected.
Stated Advantages
Overcomes excessive read distance when an attachable recording unit is located remotely from an information carrier on an RNS/medicament container.
Documented Applications
RFID/NFC information carrier reader assembly for medicament delivery devices, including syringes with an RNS and motor-driven medicament delivery devices with a reusable main body and disposable cassette.
Contactless transfer across a cassette-to-main-body interface in the example embodiments.
