The present utility model relates to portable readers (scanning devices) intended for capturing and decoding bar codes of various types, applied on different parts and components of products, preferentially on containers and test tubes in a medical analytical institution, with the aim of identification and tracking of their life cycles and with capability, if it is necessary, of simultaneous fixing the date, time, and geographical coordinates of a place of scanning.
2D bar codes present portable informative files of large density and capacity, and provide access to large amounts of information without reference to an external database. That is, 2D technology of bar coding makes it possible to store all or a major portion of necessary information in a bar code itself. 2D bar codes take a matrix form mainly and do not employ traditional bars/spacings for information encoding. Instead of conventional technique of determination of the width of a bar, for matrix bar codes, in order to conduct information encoding, are utilized the yes-no or the 1/0 constructs (i.e. the “on/off’ design). There is a great number of varieties of 2D bar codes (for example: P0P417, MaxiCode, DataMatrix).
A code structure supports encoding of the maximum number in a range from 1000 to 2000 symbols in one code with data density from 100 to 340 symbols. Each code contains start and finish groups of bar codes, which increase the height of a bar code.
2D bar codes readers, as opposite to conventional bar codes scanning devices, capture their image at first, then analyze an obtained form, and only after that extract and decode a bar code. Devices that employ analysis of a video imagery are necessary for effective reading of matrix codes. These devices, however, are capable to read conventional bar codes as well. Technology of analysis of a video imagery offers possibilities for reading signatures, for optical recognition of characters, and that like. It is known that for reading and decoding bar codes, applied on various products, are utilized scanning devices of various types.

Relevant information is displayed on the touch-sensing screen 3 and, further, depending on a user scenario, is used for transmitting to the MIS 8.
At the same time, hands of a user are not occupied with the device that makes it possible for a medical user to continue necessary procedures with a patient and/or with specimens of a patient without interruptions. In addition, the claimed device, by implementing the above-mentioned key features, allows a user to carry out the following.
Identification of a patient.
A user has an option to browse information about a patient or procedures (order) prescribed for a patient. The following scenarios are feasible for that purpose.
The orders list search.
On the touch-sensitive screen 3 are displayed the main menu (not shown in figures), on which are shown:
- the menu for selection of a model of search of the procedure (hereinafter referred as order) scheduled for a patient, according to an identifier associated with a patient, for example, according to a patient’s unique number or to an order itself;
- the personalized list of orders, meant for fulfillment by a medical user of the claimed device.
A user addresses to the home screen and chooses an active user account search.
In this case, the module 4 of interaction with external information systems requests the MIS 8 for the list of orders nearest to the date of the visit, assigned for this user, as well as the list of orders recently fulfilled by this user. Acquired information is displayed in a form of the list of orders. By browsing the order at least the following information is available:
• full name and a photo of a patient;
• the scheduled date and time of the visit;
• types of tests, prescribed to fulfill the order.
A client identifier search. A user addresses to the home screen and chooses a scanned number search in the menu. A video imagery captured by the digital camera 2 of the device is displayed on the screen. When scanning a bar code becomes available a browse button, by pushing on which the module 4 of interaction with external information systems addresses to the MIS 8 for acquisition of the list of orders associated with the information acquired from the bar code.
The result of such search may comprise the list of orders, in which a bar code acts as:
• an identifier of a client;
• a number of an order;
• a code of a test tube.
According to signals sent by the real-time clock 7 or according to information received from the external information system, the module 4 of interaction with external information systems sets the date and time of scanning.
If it is needed, scanning can be repeated for each bar code. Re-scanning of the same bar code updates a timestamp of scanning. The totality of scanned bar codes may be saved locally in the storage 6 and/or sent to the remote server.
By acquisition of information about the order (medical procedure) prescribed for a given patient, for example, about the type of a test, a user, without removing and switching off the wrist reading device starts the assigned procedure, for example, carries out a prescribed blood test and labels a test tube with a relevant bar code. This bar code is scanned by user with the same digital camera 2 as well, and, with use of the module 5 of processing of frames of streaming video, information about it is saved in the storage 6, and, by means of the module 4 of interaction with external information systems may be introduced to the MIS 8 with association with the present certain client for further use. According to signals sent from the real-time clock 7 or according to information received from the external information system, the module 4 of interaction with external information systems sets the date and time of the specified procedure. If it is needed, the claimed device may be configured in such a way that a user, without removing and switching off the wrist reading device, when making request to the MIS 8, in addition to information about an order, will receive interactive tactile, visual and/or audio prompts, in accordance with the best practices and recommendations given for the preanalytical stage of analysis.
The module 10 of acquisition and processing of information about activities of a user, along with the possibility of saving of information about activities of an user in the storage 6 and sending information about activities of a user to the remote information system, make it possible to track activities of a user in the interface and to complement this information by data received from the real-time clock 7 and the geopositioning system. For that purpose, the module 10 of acquisition and processing of information is capable to record touching the screen 3, pressing buttons, current location and time, to save data in the storage 6 and to transmit them to the external information system.
In this way, the claimed portable reader provides a user with:
• capability of carrying out manipulations with hands, for example, for sampling, simultaneously with scanning a bar code and processing of the information contained in it;
• searching and browsing the information about a patient, which is necessary for identification of a patient and for determination of specimens required to take;
• inputting and editing data about collected specimens, including their accession numbers and time of collection;
• help of the “assistant” that provides interactive tactile, visual and/or audio prompts in accordance with the best practices and recommendations given for the preanalytical stage of analysis.
