DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0018] Some terms are used to refer to specific components in the specification and subsequent claims. It is to be understood by the those of ordinary skill in the art that the hardware manufacturers may use different terms to describe the same component. The components in the specification and subsequent claims are not distinguished by their names, but by the difference in the function. The term comprising throughout the specification and subsequent claims is an open-ended term, so the term comprising is to be construed as comprising, but not limited to.

[0019] FIG. 2 and FIG. 3 are respectively a structural exploded view and a lateral cross-sectional view of a screening test paper reading system of the invention. As shown in the drawings, the screening test paper reading system 20 of the invention comprises a screening test paper 21, a test paper carrier 22, a delivery unit and a reading unit 26. The screening test paper 21 is provided with a plurality of reaction zones 211 thereon for reacting with a plurality of specific samples (e.g., urine or blood, etc.), and changing their own color. The test paper carrier 22 is provided with a bearing groove 221 thereon for accommodating the screening test paper 21 and the screening test paper 21 is fixed on the test paper carrier 22. The test paper carrier 22 is provided with a plurality of positioning parts 222 (referring to positioning points) and a gearing part 223 (e.g., a rack) thereon. The delivery unit has a driving device 25 (e.g., a DC motor or a stepper motor) and a detection device 24. When the detection device 24 detects a plurality of positioning parts 222 on the test paper carrier 22, the driving device 25 is activated and the test paper carrier 22 may be moved to a corresponding position by gearing part 223 so that the reading unit 26 retrieves a color signal on each the reaction zone 211. In the above embodiment, the specific samples comprise saliva, urine, blood, excrement, water, food, toxic and hazardous substance or microorganism. The detection device 24 may be an infrared detector, optical detector, laser detector or image sensor. The reading unit 26 may be an optical wavelength spectrometer or spectrum analyzer.

[0020] In addition, in order to enable the test paper carrier 22 will not be detached from or offset from the driving device 25 when the test paper carrier 22 is moved, the delivery unit is further provided with a caging device 23 to make the test paper carrier 22 limited to a form opening in the caging device 23 as the test paper carrier 22 moving for achieving the above purpose. The form opening of the caging device 23 may be replaced with C or opening.

[0021] Following the above-mentioned embodiment, as determining a value of urine glucose of a patient, a screening test paper specifically for urine glucose can be directly used to determine the value. The urine to be determined contacts with a reaction zone 211 of the screening test paper 21 in a form of drip or infiltration, and the component in the reaction zone 211 reacts with the urine to be determined and changes the color of the reaction zone 211. In addition, the reaction zone 211 may contain a variety of determining zones to determine glucose, protein, pH value, latent blood value or other physiological values in urine to achieve an effect of multiple values with one screening. After the urine to be determined contacts and reacts with the reaction zone 211 of the screening test paper 21, the screening test paper 21 may be provided in the bearing groove 221 of the test paper carrier 22, and the test paper carrier 22 is inserted into a spectrum analyzer (i.e., the screening test paper reading system 20 of the invention).

[0022] When the test paper carrier 22 is inserted to a certain depth, the detection device 24 may detect a plurality of positioning parts 222 on the test paper carrier 22 (shown as dot appearance on the test paper carrier 22 in FIG. 2), at this time the screening test paper reading system 10 of the invention may determine that there is a screening test paper inserted and carrying out screening operations is desired, and the driving device 25 such as a DC motor or a stepper motor is activated and the test paper carrier 22 may be moved to the corresponding position by the gearing part 223 such as a rack. Generally speaking, it is an aspect of sucking up the test paper carrier 22. Because the specifications of the screening test paper 21 and the moving distance of the test paper carrier 22 driven by the driving device 25 are fixed or predetermined, it will be quite accurate for the test paper carrier 22 to move to the corresponding position for the reading unit 26 to retrieve the color signal of each reaction zone 211, which is positioning in one time. Next, the reading unit 26 may retrieve the color signal of each reaction zone 211, and the color signal is treated by a spectrometer to achieve a purpose of fast screening.

[0023] Moreover, because the screening test paper 21 is provided in the bearing groove 221 of the test paper carrier 22 that is not the way of directly contacting with the spectrum analyzer, the screening test paper 21 is protected by the test paper carrier 22, and not easy to wear.

[0024] It is to be understood by the those of ordinary skill in the art that the above preferable embodiments of the invention are described in detail and the various possible modifications and alterations of the embodiments could be made, without departing from the scope and spirit of the invention. The various embodiments such as caging unit are not limited by the way carrying out the embodiments in the specification.
