Since different test samples require different substances for their detection, different test types are required for different test types. For example, if you want to test blood sugar, you need to take a blood glucose test strip, and if you test uric acid, you need to take a uric acid test strip. In addition, to ensure the correctness of the test results, test pieces that have not expired must be used. The detection machine of the prior art usually uses an additional calibration chip to store the calibration data such as the test piece type, batch number and shelf life. When performing the test, the calibration wafer corresponding to the test test piece type and the batch number is inserted into the test machine, the test machine reads the correction information in the correction wafer, and displays the test piece type, the test piece batch number, the shelf life, and the like. On the testing machine, the user confirms whether the test piece to be used is the same as the type, batch number, and correction information displayed on the machine, and whether the test piece exceeds the service life. In addition, since the correction wafer can also carry the detection value correction information of the test piece to which the batch number belongs, it is necessary to perform detection using a test piece of the same number as the correction wafer to ensure the most accurate detection result.

The correctness and protection of the operator from biological contact with biological specimens. In addition, this design can also avoid the disadvantage of being difficult to remove due to poor design of the test strip.

Referring to FIG. 1A, the optical reader 4 is disposed inside the casing 1 for reading the identification information in the optically readable pattern 22 of the test strip 20, and the reading is located on the test strip 20. The optically readable pattern 22 can be read in two ways. First, while the transporting mechanism 3 moves the test strip 20 into the interior of the casing 1, it is read by the optical reader 4 on a path preset by the transport mechanism 3. The optically readable pattern 22 of the test strip 20 is tested. Alternatively, after the test strip 20 is moved by the transport mechanism 3 to a predetermined path end point, the optically readable pattern 22 of the test strip 20 is read by the optical reader 4. Further, it is preferable that the optical reader 4 and the detection signal reader 5 are provided on the upper and lower sides of the path set in advance by the transport mechanism 3.

Referring to FIG. 1B, the optical reader 4 may also be disposed at the side of the housing 1. This arrangement is designed such that the optically readable pattern of the test strip 20 is read by the optical reader 4 before the test strip 20 is placed in the transport mechanism 3. In addition, the optical reader 4 can also read the medical record barcode or ID barcode of the test subject corresponding to the test strip 20, thereby confirming whether the test strip 20 is owned by the test subject, and has the effect of correcting again. The subject is integrated with the data of the test strip 20. In addition, the optical reader 4 is detachably detachable from the housing 1 for user convenience. The detached optical reader 4 can be communicated to the test strip reading device 100 by wireless transmission or wire transmission.

Such an optically readable pattern 22 on the test strip carries information such as the type, batch number, expiration date, and reagent correction data corresponding to the lot number of the test strip, and is read by the test strip reading device. The method of information can effectively avoid the user's misuse of the expired test strip 20 due to manual confirmation or manual input of the test strip related data, which leads to waste of the sample, or even affects the analysis result. The correctness.

The detection signal reader 5 is disposed inside the casing 1 for reading the fluid detection signal emitted by the fluid reaction zone 21 of the test strip 20, wherein the fluid detection signal can detect the photoreaction signal or the electrochemical reaction signal. There are also two ways in which the detection signal reader 5 reads the fluid detection signal. First, the detection test piece 20 can be read by the detection signal reader 5 in a predetermined path while the detection test piece 20 is moved into the casing 1, and the fluid detection signal emitted from the test piece 20 can be read. The second is that after the test strip 20 is moved by the transport device 3 to the end point of the preset path, the detection signal reader 5 reads the fluid detection signal from the test strip 20.

The control module 6 includes a database module 61 and an operation module 62. The database module 61 is a fluid detection signal data storing a plurality of types of test strips, for example, fluid detecting data required for various types of blood glucose, total cholesterol or uric acid.

Moreover, the operation module 62 can further interrupt or allow the detection signal reader 5 to read the fluid detection signal emitted by the detection test strip 20 according to the use period data of the test strip 20.

For example, when the blood glucose test is performed, after the test strip 20 is sent to the test strip reading device 100, the optical reader 4 reads whether the type of the test strip 20 belongs to the blood glucose test, and simultaneously reads Information such as the lot number and the expiration date of the test piece contained in the optically read pattern 22 is automatically compared by the test strip reading apparatus 100. After the data of the test piece type and the expiration date are confirmed, the detection signal reader 5 reads the fluid detection signal emitted by the test strip 20. After the test strip reading apparatus 100 confirms that the test strip 20 is a test piece for blood sugar test, the blood pool test-related fluid detecting signal data is provided by the database module 61, and then optically read in conjunction with the detecting test piece 20. The reagent calibration data on the pattern 22 and the fluid detection signal sent from the detection test strip 20 read by the detection signal reader 5 are sent to the operation module 62 for calculation, and finally the blood glucose detection result is obtained.
