The VBM automatically checks the contents of every blister cavity and makes a comparison with the prescribed medicines and the model library. Using various software algorithms, the VBM and quickly and accurately checks the shape, colour and number of pills. This technology has proved very successful in verifying medicine pouches and it has been adapted for use in the VBM to check blister cards.
We have implemented RFID technology in several stages of the process, making it safer and more accurate. Every cartridge has an RFID tag making it possible to identify it in the VBM machine. Characteristics of each cartridge can be saved in the database and help the VBM to operate more efficiently. All blister card holders are also equipped with RFID chips, making it also possible to identify the trays.
The VBM’s critical areas are protected from dust – as soon as the blister card is filled, it is covered. This cover stays in place until the tray is sealed with the blister carton. Dust meters are placed in the cartridge towers so that when a certain level of dust or pollution is reached, the system warns the operator that the tower needs cleaning.
The VBM uses specially developed software to control the filling and checking of the blister cards. Constant monitoring of the process is made clear via the user interface. Control by touch screen makes it easy to operate the machine.
The original prescription is transferred from the host system to the VBM database by specially developed software.
The required tablets for one dose are dispensed by the cartridges.
Any remaining medicine or other medication is dispensed by the MDA tray.
All medicines are checked by the visual controller. The contents of each cup in the blister card are photographed for future reference.
Only the correct dosage will be placed in the each cup. When the blister card is filled, the VBM completes the process and the card leaves the machine for action by the operator.
