Abstract
The present invention relates to a method for obtaining lot variation information of a diagnostic cartridge, and to an in vitro diagnostic device using the same method. The method of the present invention includes obtaining item information and lot information of the diagnostic cartridge; generating a QR code having an internet address for obtaining lot variation information using the obtained item information and lot information; and displaying the QR code on the display.
Core Innovation
The invention relates to an in vitro diagnostics device including a display and a storage, for obtaining lot variation information of a diagnostic cartridge. A diagnostic cartridge is scanned to obtain item information and lot information, and the obtained item information and lot information are used to check whether corresponding lot variation information exists in the storage.
In response to determining that the lot variation information does not exist in the storage, the control unit generates a first QR code including an internet address for obtaining lot variation information using the obtained item information and lot information. The first QR code is displayed on the display for scanning by a mobile device, and a second QR code is received from the service server through the internet address, where the second QR code includes the lot variation information.
The lot variation information is extracted from the second QR code and stored in the storage for analyzing the diagnostic cartridge. The diagnostic cartridge is analyzed using the stored lot variation information.
Claims Coverage
Two independent claims are identified: a method claim and a device claim. Both claims share the core workflow of scanning a diagnostic cartridge to obtain item information and lot information, checking storage for lot variation information, and, if absent, retrieving lot variation information using a QR-code workflow linked to an internet address and a service server, then storing it for subsequent analysis.
Retrieving lot variation information via QR code with internet address when absent in storage
A method for obtaining lot variation information of a diagnostic cartridge, comprising scanning the diagnostic cartridge to obtain item information and lot information, checking in storage whether lot variation information corresponding to the obtained item information and lot information exists, and in response to determining that the lot variation information does not exist in the storage generating a first QR code including an internet address for obtaining lot variation information, displaying the first QR code for scanning by a mobile device, receiving a second QR code displayed on the mobile device including the lot variation information obtained from a service server through the internet address, extracting and storing the lot variation information from the second QR code in the storage, and analyzing the diagnostic cartridge using the stored lot variation information.
IVD device with dual scanners, QR-code internet retrieval, storage, and cartridge analysis
An in vitro diagnostics device comprising a first scanner for scanning a diagnostic cartridge to obtain item information and lot information, a storage for storing item information, lot information, and lot variation information, a second scanner for scanning a QR code containing lot variation information, a control unit configured to check whether lot variation information corresponding to the obtained item information and lot information exists in the storage, and in response to determining that the lot variation information does not exist in the storage generate a first QR code including an internet address for obtaining lot variation information using the obtained item information and lot information, receive via the second scanner a second QR code displayed on a mobile device including the lot variation information obtained from a service server through the internet address, extract the lot variation information from the second QR code and store the extracted lot variation information in the storage, and a display for displaying the QR code including the internet address, wherein the control unit is further configured to analyze the diagnostic cartridge using the stored lot variation information.
The independent claims cover a method and a corresponding IVD device architecture that retrieve missing lot variation information through a QR-code workflow using an internet address and a service server, then store the lot variation information for cartridge analysis.
