Description

Laboratory instrument coupling system and method based on handheld intelligent terminal

The present invention relates to the field of laboratory testing technology, and in particular, to a laboratory instrument coupling system and method based on a handheld intelligent terminal. Background technique

When using various information systems, such as LIMS (Laboratory Information Management System), ELN (Electronic Laboratory Notebook), and LIS (Laboratory Information System), the laboratory generally needs to collect test results from various laboratory analytical instruments. , used to generate test reports or experimental reports. In all types of laboratories, the analytical instruments used can be divided into three categories according to the type of data interface they are configured, including instruments with PC workstations, instruments without a PC workstation but with an RS232 data interface, and without any Instrument for data interface. Some of these instruments, although not equipped with an RS232 interface but with a printer interface, can be converted to an RS232 interface and classified as an instrument without a PC workstation but with an RS232 data interface. Instruments without any data interface include test methods that do not have actual instruments, but simply use human senses to directly give decision data, such as color observations. Such "instruments" can be classified as instruments without any data interface.

At present, the instrument coupling technology for the purpose of automatic data acquisition can better solve the problem of the connection of instruments with PC workstations, but for the automatic data acquisition of instruments without PC workstations with RS232 interface, the instruments are all RS232 interface with cable directly with information The serial port of the client PC of the system is connected. This type of instrument connection is used during data acquisition. Because the instrument has no data input and confirmation equipment in the near future, the laboratory operator needs to move back and forth between the instrument and the client PC to match the sample ID. In order to avoid frequent movements of people, placing a PC next to each instrument requires a lot of PCs and a large number of laboratory countertops. Even so, each PC requires a long boot time and requires operator input each time. The user name and password requirements are also cumbersome for the operator, so most operators are reluctant to accept this automatic data collection, and prefer to manually use these instruments without a PC workstation with an RS232 interface and without any data. The interface instruments are treated together, that is, the test results of the instruments are first recorded on paper, and then the results are input into the information system through the client PC. This method of manually transcribed data greatly increases the error rate and may not be related to Laboratory specifications.

How to improve the data input efficiency and quality of these instruments with RS232 interface and instruments without any data interface is one of the biggest difficulties faced by laboratory informationization for many years. Summary of the invention

A laboratory instrument connection system based on a handheld intelligent terminal provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. In the following description, a number of different aspects of the invention will be described, however, it will be apparent to those skilled in the art that the invention may be The specific numbers, configurations, and sequences are set forth for clarity of explanation, but it is obvious that the invention may be practiced without these specific details. In other cases, in order not to confuse the invention, for some well known Features will not be elaborated.

The present invention uses a handheld intelligent terminal configured with data acquisition software, such as a tablet computer, a handheld PC, a personal digital assistant (PDA), and a smart mobile phone (smartphone) to analyze various instruments of the laboratory with an RS232 interface. The data is automatically and conveniently input into the information system. At the same time, the handheld intelligent terminal can be used to quickly and conveniently input the data of instruments without any data interface, so that the laboratory can achieve a convenient, accurate and efficient paperless level.

The present invention uses a handheld intelligent terminal equipped with instrument data input software and equipped with a bar code scanning device and/or a radio frequency (RFID) tag reading device, interconnected by a wireless signal and an instrument-connected server, and then analyzed with an RS232 interface. The instrument is connected to the instrument connection server through RS232 to TCP/IP protocol converter. The instrument connection server is connected with the server of the laboratory information system to share security information such as user name and password (the instrument connection system and related laboratory information system can generally Share one server, but you can also use different servers). When the operator conducts sample analysis test next to the analytical instrument, it only needs to scan the instrument's coded label with a hand-held intelligent terminal, such as a barcode label or a radio frequency label, and then scan the sample code label, and then use the instrument to analyze and test the sample. The test results are automatically collected by the protocol converter and transmitted to the handheld smart terminal. The operator presses the button to confirm that the data is automatically collected, and the test result is immediately written into the database of the information system, thereby completing the automatic data acquisition process for the instrument with the RS232 interface.

For an analytical instrument without any data interface, the handheld smart terminal is used to scan the instrument coded label, and then the coded label of the sample is scanned, and the data input box is automatically displayed on the handheld smart terminal. After the operator analyzes the sample with the instrument, the test result is directly input through the keyboard of the handheld intelligent terminal, and then confirmed, that is, the input of the test result is completed. Specifically, the handheld smart terminal used in the present invention should be equipped with a camera in order to enable reading of the barcode. If the bar code scanning requirements are high, a dedicated barcode reader can be equipped. If you need to read the RF tag, you should have a corresponding RF tag reader. The device can be equipped with at least one wireless component, such as Wi-Fi and Bluetooth, to communicate with the server, depending on the specific laboratory requirements. If the device needs to work in a remote area, consider implementing a 3G/4G cellular mobile communication component for long-distance wireless connectivity.

As shown in Figure 1, in the network where the instrument connection server is located, the RS232 to TCP/IP protocol converter connects the instrument with RS232 interface to the network by wire or wirelessly. Generally, one converter can be connected at the same time. 1 to 4 instruments. Wireless communication with a handheld intelligent terminal is performed by a wireless router connected to the network. An instrument without a data interface can directly input the analysis result using the handheld intelligent terminal. The relevant intelligent data collection software is installed in the handheld intelligent terminal and the instrument connection system server, and the security information such as the user name and password in the related information system can be shared.

As shown in Figure 2, before the operator begins to use the instrument with the RS232 interface for sample testing, the instrument coded label used is scanned using the handheld smart terminal that has been logged in the information system. The server automatically queries the scanned instrument through the information system and displays a list of samples that the instrument can test on the smart terminal. The operator scans the sample code label to be tested with the handheld smart terminal, and the system automatically selects the sample according to the sample code and displays the input box of the test result on the handheld smart terminal.

Depending on the operator's habits and system settings, you can also scan the coded label of the sample before scanning the instrument's coded label. Thus, after scanning the sample coded label, a list of instruments that can be tested for the sample is displayed on the handheld smart terminal. After displaying the input box of the test result, the handheld smart terminal will automatically send a data acquisition request to the instrument connection server. The server will automatically open the RS232 interface of the instrument through the protocol converter. After the instrument completes the test, it will automatically send the test data through the RS232 interface. Some instruments require the operator to send data on the panel of the instrument before sending the data.

The data sent by the instrument is transmitted to the instrument connection server through the protocol converter. Most of the data of this instrument has only one result, and the instrument connection server will automatically send the result to the input box of the handheld intelligent terminal. The data of a few instruments is more complicated, so that the instrument connection server automatically processes and selects the data according to the preset trade-off rules, and sends the selected result to the input box of the handheld intelligent terminal.

Sometimes, in order to transmit the instrument test results to the handheld smart terminal more quickly, under the condition that the processing capability of the handheld smart terminal is sufficiently strong, the input box of the test result can be displayed on the handheld smart terminal, and the handheld smart terminal directly passes The protocol converter automatically opens the RS232 interface of the instrument. After the instrument completes the test, it automatically sends the test data directly to the handheld intelligent terminal through the RS232 interface. In the case where the test data of the instrument is complicated, the handheld intelligent terminal can be used instead of the instrument connection server. The preset trade-off rules automatically process and select these data, and display the selected result in the input box of the handheld smart terminal.

After the operator sees the test result displayed by the handheld intelligent terminal, the test result can be directly confirmed on the panel, and the result will be immediately written into the database of the information system, and the entire test data automatic acquisition process is completed. In order to ensure the reliability of the test result input of such instruments, it can be set in the system that the test results of this type can only be automatically collected from the instrument and cannot be manually input, only after the automatic acquisition fails and the relevant authorization is obtained. You can enter the results directly by hand.

As shown in Figure 3, before the operator starts to use the instrument without the data interface for sample testing, use the handheld intelligent terminal that has been logged in the information system to scan the instrument code label used. The information system automatically queries the scanned instrument and displays a list of samples that the instrument can test on the smart terminal. The operator then scans the sample code label to be tested with the handheld smart terminal, and the information system automatically selects the sample according to the sample code, and displays the input box of the test result on the handheld smart terminal.

Depending on the operator's habits and system settings, you can also scan the coded label of the sample before scanning the instrument's coded label. Thus, after scanning the sample coded label, a list of instruments that can perform the sample related test is displayed on the handheld smart terminal. After displaying the input box of the test result, the operator performs the sample test, and directly inputs the test result displayed by the instrument into the handheld intelligent terminal by keyboard and confirms the key. After confirming, the result will be immediately written into the database of the information system. In the whole test result input process is completed. If you need to further reduce the error rate of manual input, you can set each test result to be manually input 2 times or more. Only after these multiple input results are completely matched, the system will accept this data.

Finally, it should be noted that the above embodiments are only used to describe the technical solutions of the present invention and are not intended to limit the technical methods. The present invention may be extended to other modifications, changes, applications, and embodiments, and thus all such Modifications, variations, applications, and embodiments are within the spirit and scope of the invention.
