Description

Screening test paper reading system

The invention relates to a screening test paper reading system, in particular to a screening test paper reading system that can achieve the effects of rapid screening and protection of the screening paper.

According to people, as human beings pay more and more attention to their physical health, screening, including physiological screening or environmental screening, has become a very hot topic. FIG. 1 is a schematic diagram of a conventional screening test paper. As shown in the figure, the screening test paper 10 is provided with a reaction zone 11. When the user drops the specimen on the reaction zone 11, the reaction zone 11 will chemically react with the specimen, and the color of the reaction zone 11 will change. The user can judge whether the specimen is normal or not according to the color change and contrast color of the reaction zone. However, the accuracy of recognizing color changes through the human eye is very poor, so when performing precision screening, most of them are performed with a spectrum analyzer.

However, when using a spectrum analyzer for screening, the user avoids manually placing the screening test paper at the corresponding position for the spectrum analyzer to capture the color signal of the reaction zone. This will not only easily cause the screen testing paper to wear out. , It is more likely to cause the dilemma of inaccurate placement and unrecoverable, and waste a lot of time in adjusting the position of the screening test paper, so it is difficult to be called practical.

Certain terms are used in the description and the scope of subsequent patent applications to refer to specific elements. It should be understood by those with ordinary knowledge in the art that hardware manufacturers may use different names to refer to the same component. The scope of this specification and subsequent patent applications does not take the difference in names as a way to distinguish components, but rather uses the difference in functions of components as a criterion for distinguishing components. "Inclusion" mentioned throughout the specification and subsequent claims is an open-ended term and should be interpreted as "including but not limited to."

Figures 2 and 3 are the results of the screening test paper reading system of the present invention. An exploded view and a side cross-sectional view are as shown in the figure: The screening test paper reading system 20 of the present invention is mainly composed of a screening test paper 21, a test paper carrier 22, a conveying unit, and a reading unit 26. The screening test paper 21 is provided with a plurality of reaction zones 211, which can generate chemical reactions on a number of specific specimens (such as urine or blood, etc.) and change its own color. The test paper carrier 22 is provided with a bearing slot 221 for receiving the screening test paper 21 and fixing the screening test paper 21 to the test paper carrier 22. The test paper carrier 22 is further provided with a plurality of positioning portions 222 (general designated points) and a linkage portion 223 (which may be a rack). The conveying unit has a driving device 25 (which may be a DC motor or a stepping motor) and a detection device 24. When the detection device 24 detects a plurality of positioning portions 222 on the test strip carrier, the driving unit The device 25 is activated and moves the test strip carrier 22 to a corresponding position through the linkage unit 223, so that the reading unit 26 captures the color signals on the respective reaction areas 211. The specific specimen in the above embodiment may be The application range is saliva, urine, blood, feces, water, food, toxic and harmful substances or microbial reactions. The above-mentioned detection system 24 series can be replaced with infrared detectors, light detectors, laser light detectors or images. The sensor, the reading unit 26 is an optical wavelength spectrometer or a spectrum analyzer.

In addition, in order to prevent the test strip carrier 22 from being detached from or shifted from the driving device 25 when moving, the conveying unit is further provided with a limiting device 23, wherein the operation mode makes the test strip carrier 22 move, where The test strip carrier 22 is restricted to slide inside the "ㄈ" -shaped opening of the stopper 23 to achieve the above purpose. The appearance of the opening of the stopper 23 can be further replaced with an opening such as "C" or "ㄇ".

Continuing the above embodiment, if the urine glucose value of the patient is to be tested, if it has been determined that the screening test paper obtained is dedicated to urine glucose, the test can be directly performed, that is, the reaction zone between the urine to be tested and the test paper 21 211 makes contact (usually by dripping or infiltration), the components in the reaction zone 211 will chemically react with the urine to be detected, and change the color of the reaction zone 211. In addition, the reaction zone 211 may include a plurality of different detection zones for detecting glucose, protein, pH value, occult blood value, or other physiological values in urine to achieve the effect of screening multiple values at one time. After the urine to be tested comes into contact with the reaction zone 211 of the screening test paper 21, the screening test paper 21 can be placed in the loading slot 221 of the test paper carrier 22, and the test paper carrier 22 can be inserted into the spectrum analyzer (i.e., the present invention 20).

When the test strip carrier 22 is inserted to a certain depth, the detection device 24 will detect a plurality of positioning portions 222 on the test strip carrier (see the appearance of the dots on the test strip carrier 22 in FIG. 2). The screening test paper reading system 10 will determine that the screening test paper is inserted to perform the screening operation. The driving device 25 will be started. The driving device 25 is a DC motor or a stepping motor, and the transmission device is a rack. The linking unit 223 drives the test paper carrier 22 to the corresponding position, which is similar to the state that the test paper carrier 22 is inhaled. Because the specifications of the screening test paper 21 and the distance that the driving device 25 uses to drive the test paper carrier 22 are fixed or set parameters, the test paper carrier 22 is moved to a reading unit 26 to capture each reaction zone. The corresponding position of the color signal on 211 will be quite accurate, and it will be positioned once. Subsequently, the reading unit 26 captures the color signals on each reaction zone 211 and performs spectroscopic processing to achieve the purpose of rapid screening.

Furthermore, since the screening test paper 21 is placed in the bearing groove 221 of the test paper carrier 22 and is not in direct contact with the spectrum analyzer, it is protected by the test paper carrier 22 and is not easily worn.

After explaining the above-mentioned preferred embodiments of the present invention in detail, those skilled in the art can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the patent application described below, such as various implementation modes of the limit unit It is not limited to the implementation of the examples in the description.
