Since the present invention discloses a test strip reader, the basic structural principles of the biodetection process, the related test strips, and the mechanism actuation used therein have been known to those of ordinary skill in the related art, and therefore, Description, no longer a complete description. At the same time, the drawings referred to in the following texts express the structural schematics related to the features of the present invention, and need not be completely drawn according to the actual size, which is first described.

First, please refer to Fig. 1, which is a schematic diagram of the test strip reader of the present invention. As shown in FIG. 1, the test strip reader 10 includes a housing 100, a display 200, a transport mechanism 300, a barcode reader 400, an optical reader 500, a motherboard 600, an operation switch 700, and an input keyboard. 800 and interface device 900 and the like. In the present embodiment, the display 200, the transport mechanism 300, the barcode reader 400, the optical reader 500, the operation switch 700, the input keyboard 800, and the interface device 900 in the test strip reader 10 are both flexible. The flexible bus is electrically connected to the motherboard 600. Of course, the display 200, the transport mechanism 300, the barcode reader 400, the optical reader 500, the operation switch 700, the input keyboard 800, and the interface device 900 in the test strip reader 10 can also be directly electrically connected to the motherboard 600. Secured together. All of the above are embodiments of the present invention.

Further, in the test strip reader 10 of the present invention, a firmware unit 30 is further included as shown in Fig. 1B. The firmware device 30 is electrically connected to the electrical connection end 610 of the motherboard 600, and includes a circuit substrate (not shown), and an electrical connection end 32 is formed at one end of the circuit substrate for electrical connection. The connection terminal 610 is electrically connected; at the same time, the database module of the firmware device 30 is further provided with a database module 34 and a computing module 36, wherein the database module 34 stores a plurality of photoreactions for detecting the test strips. equation.

Next, the operation of the test strip reader 10 of the present invention will be described. The display 200 is disposed on the housing 100 and can be used to display a detection state or a detection result. The transport mechanism 300 is configured to carry a test strip 20 disposed with a bar code and horizontally move according to a preset path, so that the test strip 20 can be automatically moved into or removed from the housing 100; The bar code on the 20 can be scanned, so the transport mechanism 300 of the present invention can be a transparent carrier or a transparent carrier at the position where the test strip 20 is carried, or placed on the test strip 20 A bare structure is formed; therefore, the barcode reader 400 disposed in the housing 100 can quickly and stably scan the barcode on the test strip 20 to read the barcode information on the test strip 20. The type of the barcode on the test strip 20 may be a one-dimensional barcode (One Dimensions Barcode) or a two-dimensional barcode (Two Dimensions Barcode), and the barcode information stored in the barcode includes: a test strip. Correction information for category 20, date of manufacture, manufacturing lot number, expiration date, or lot number.

In addition, the barcode reader 400 of the present invention has the following two reading modes. The first reading mode is: when the detecting test strip 20 is moved into the casing, the conveying mechanism 300 moves according to a preset path, and The barcode information on the test strip 20 can be simultaneously read during the moving process; the second read mode is: when the test strip 20 is moved to the end of the path by the transport mechanism 300, the read test strip 20 is read again. Barcode information. Obviously, after the bar code reader 400 reads the bar code information on the test strip 20, the type of the test strip 20, the date of manufacture, the manufacturing lot number, and the effective date can be correctly known according to the content of the bar code information. Or correction data for the batch number. Therefore, in the process of detection, it is possible to effectively avoid misuse of test samples that are incorrect or have expired to ensure the correctness of the test results. After confirming that the test strip 20 is still within the expiration date, the barcode reader 400 transmits the category information of the test strip 20 to the computing module 36 on the firmware device 30 for selecting the library module 34. Corresponding light reaction equations and performing their subsequent detection procedures.

It is further explained that the detection procedure may be partially different with different detection test pieces. In the cold light detection mode, the light emission reaction is self-luminous, so that the light signal reaction can be generated without irradiating the light source. The fluorescent detection method needs to be irradiated by a light source to cause energy conversion after the energy is received and generate an optical signal reaction. For example, when the material on the test strip 20 is a luminescent material, the illuminating reaction can be generated without irradiation of the light source device; and the test strip 20 using the fluorescent method for coloring needs to pass through. After the irradiation of the light source device, the fluorescent material on the test strip 20 is caused to generate an optical signal reaction. Therefore, a light source device (not shown) can be selectively disposed in the test strip reader 10 of the present invention. Taking the fluorescent detecting method as an example: when the detecting test piece 20 is determined by the barcode reader 400 to be a fluorescent color detecting test piece 20, the detecting test piece reading machine 10 provides a light source detecting test. The sheet 20 is continuously irradiated, and then the specific light reaction parameters on the test strip 20 are read by the optical reader 500 and transmitted to the arithmetic module 36 on the firmware unit 30.

As described above, the firmware device 30 of the present invention includes a database module 34 and an arithmetic module 36. Various types of light reaction equations for detecting test strips 20 are stored in the database module 34, for example, a light reaction equation for testing blood sugar, cholesterol or hemoglobin. Therefore, when the operation module 36 reads out the barcode information on the test strip 20 through the barcode reader 400, and selects a corresponding light reaction equation from the database module 34 according to the test strip category in the barcode information; The batch correction data in the information is loaded into the photoreaction equation with the specific photoreaction signal read by the optical reader 500, and a detection result is generated after calculation. It should be emphasized here that the detection result in the present invention may be an arithmetic value (value), which may also be raw data that has not been processed. The result of the detection can be displayed via the display 200 or transmitted through the interface device 900. For example, when the test strip 20 is a blood glucose test strip, the test strip 20 is loaded into the test strip reader 10, and the barcode reader 400 automatically reads the test strip 20 at this time. Bar code information, including: category, date of manufacture, manufacturing lot number, expiration date or correction data of the batch number, etc.; then the computing module 36 selects the light of the blood glucose test piece from the database module 34 according to the content of the bar code information. The reaction equation is further loaded into the equation by the batch calibration data and the specific light reaction signal read by the optical reader 500, and the detection result is obtained after the operation. The database module 34 in this embodiment may be a write once memory, or it may be a non-volatile memory component, which is a non-volatile memory component. Can be: a planned read-only memory (OTP-ROM), flash memory, wipeable programmable read-only memory (EPROM) or electrically erasable programmable read-only memory ( EEPROM) and so on.

In the above detection process, the test strip reader 10 determines the various conditions and programs based on the bar code information on the test strip 20, for example, when the barcode reader 400 uses the read test piece. After the time limit is compared with the date of the test day, if the test strip 20 has exceeded the usable period, the test strip reader 10 immediately interrupts the test program and displays the related message on the display 200. For example, if the test strip 20 is a uric acid test strip within a lifetime, when it is loaded into the test strip reader 10, it is judged based on the barcode information read by the barcode reader 400. It is a uric acid test piece and has not exceeded the time limit for use. Then, the light reaction equation of the uric acid test piece is correspondingly extracted from the database module 34 and loaded into the calculation module 36, and then the batch of the test piece is corrected. The data is calculated by calculating the light reaction data taken by the optical reader 500 to obtain the detection result.

In addition, the test strip reader 10 further includes an input keyboard 800 through which an identifier of the subject (for example, an ID card number, a health care card number, a social security code, or a medical record number) is input. When the detection result is displayed on the display 200 or output through the interface device 900, the correlation between the detection result and the subject can be distinguished. In addition, when the bar code information on the test strip 20 cannot be correctly read by the bar code reader 400, the type of the test strip 20, the date of manufacture, the manufacturing lot number, the effective date or the correction of the lot number can also be detected through the input keyboard 800. The data and the like are manually input so that the test strip reader 10 can continue to operate.

Next, please refer to Fig. 2, which is a schematic view showing another side of the test strip reader 10 of the present invention. As shown in FIG. 2, an interface device 900 is disposed on the other side of the test strip reader 10 of FIG. 1 for outputting a detection result. The interface device 900 can be a printer connection.埠910, USB port 埠920, RS232 port (not shown), Bluetooth port (not shown), ZigBee port (not shown) or Wireless USB port (not shown), etc. Configuration. It is obvious that the interface device 900 is electrically connected to the motherboard 600 and is disposed on the housing 100. In particular, the printer port 910 can also be directly connected to a printer module and built into the test strip reader 10 to facilitate the user to print the test results immediately; and the USB connection埠920, RS232 port, etc., can be connected to a personal computer (PC) to store or analyze the test results; and Bluetooth port (not shown), ZigBee port or Wireless USB port, etc. The detection result is transmitted to another device through the corresponding receiver, for example, a remote file server.

Next, please refer to Fig. 3, which is a schematic view of another embodiment of the test strip reader 10 of the present invention. As shown in FIG. 3, the embodiment includes a test strip reader 10 and a firmware device 30, wherein the structure of the test strip reader 10 is the same as that of the embodiment of FIG. 1, and the difference is only in this embodiment. The firmware device 30 of the embodiment can be electrically connected to the electrical connection end 610 on the motherboard 600 via a connection slot 620 on the housing 100. Obviously, the electrical connection end 610 of the embodiment has been disposed on one end of the motherboard 600 (not shown) and corresponds to a connection slot 620 on the housing, so the firmware device 30 can be easily Moreover, it is convenient to electrically connect or remove the electrical connection end 610 on the motherboard 600. When the firmware device 30 in this embodiment is electrically connected to the electrical connection end 610 on the motherboard 600 via the connection slot 620 on the housing 100, the structure is completely the same as that in the embodiment of FIG. 1. For example, the operation of the test strip reader 10 will not be repeated.

In particular, since the firmware device 30 of the present invention is detachably electrically connected to the electrical connection end 610 of the motherboard 600, the firmware can be updated by replacing the firmware device 30. The reader 10 controls the purpose of the program to ensure the stability of the test equipment and the correctness of the test results. In addition, since the firmware device 30 is very small in size, the manufacturer can send the new firmware device 30 to the user via Express, eliminating the risk of shipping the test equipment and the time wasted. For the convenience of users.
