Based on the above problem, the utility model provides a location urine analysis test paper device, its each part constitute as shown in figure 1: a test paper substrate 100; a plurality of project paper blocks 200 arranged on the test paper substrate 100, wherein the project paper blocks 200 are used for bearing test samples; and a positioning detection hole 110 disposed on the test paper substrate 100 and used for cooperating with a predetermined reflective optical coupler sensor 500 (as shown in fig. 2) to position the test paper substrate 100.
The utility model discloses a set up location inspection hole 110 on test paper substrate 100 to urine analysis test paper device, through cooperating with predetermined reflection type optical coupling sensor 500, thereby it is right urine analysis test paper device advances line location, when askew strip takes place for location urine analysis test paper device, reflection type optical coupling sensor 500 can not normally realize the sensing effect, consequently sends out the police dispatch newspaper and reminds the detection people to stop urine detection analysis instrument operation, avoid appearing the testing result and have the mistake or detect the problem that sample sequence number and result correspond the mistake.
In specific implementation, as shown in fig. 1, the utility model is provided with a project paper block 200 on the test paper substrate 100, wherein the project paper block 200 is used for bearing a test sample, namely urine of a patient, for performing photoelectric detection; the test paper substrate 100 is further provided with a positioning detection hole 110, the positioning detection hole 110 is matched with a preset reflective optical coupling sensor 500 (as shown in fig. 2), so as to limit the positioning detection hole 110, when the positioning urine analysis test paper device is skewed, the extensions on four sides of the positioning detection hole 110 (i.e., the test paper substrate 100) shield the reflective optical coupling sensor 500, so as to block normal propagation of a reflected signal, and when the reflective optical coupling sensor 500 cannot normally receive a signal, the reflective optical coupling sensor sends an alarm, so as to achieve an effect of positioning the test paper substrate 100.
Further, the positioning detection holes 110 are provided at both left and right ends of the test paper substrate 100, and the positioning detection holes 110 are respectively provided at least one on the left and right of the test paper substrate 100, in one embodiment, as shown in fig. 2, when the test strip substrate 100 is provided with one positioning detection hole 110 on each of the left and right sides, two ends of the test paper substrate 100 are respectively provided with a reflective optical coupler sensor 500 matched with the positioning detection hole 110, that is, the strip substrate 100 is positioned on both the left and right sides, and when the urine analysis strip is misaligned, at least one end of the test paper substrate 100 may block the normal reflected signal of the reflective optical coupler sensor 500, therefore, the positioning detection hole 110 and the reflective optical coupling sensor 500 can be matched to effectively detect the condition of the bending of the positioning urine analysis test paper device.
In the practical application process, the farther the two positioning detection holes 110 are separated from each other, the better the detection effect on the skew condition, because the farther the position moving distance from the geometric center point of the test strip substrate 100 is, when viewed from the moving locus of the positioning urine analysis test strip device, the same skew angle is, the longer the position moving distance is, and therefore, when the distance between the two positioning detection holes 110 is longer, the more the positioning detection holes 110 deviate from the predetermined position in the case of skew, the greater the probability that the extensions on the four sides of the positioning detection holes 110 (i.e., the test strip substrate 100) block the reflective optical coupling sensor 500 is, and therefore, the better the positioning effect is generated when the two positioning detection holes 110 are separated from each other; meanwhile, in other embodiments of the present invention, the number of the positioning detection holes 110 and the reflective optical coupling sensors 500 cooperating with the positioning detection holes 110 may be increased according to different structures of the urine analysis and detection instrument, so as to further improve the detection accuracy of the skew strip.

Further, the item paper blocks 200 are sequentially arranged on the test paper substrate 100 at intervals from left to right, and the advantage of the interval arrangement is that when a liquid dropping machine drops a test sample on the item paper blocks 200, the situation that the sample to be tested is not dropped due to the fact that a liquid dropping instrument is not stretched in place may occur, and the situation that the sample to be tested is dropped may occur, and the situation that the sample to be tested cannot be detected by a probe in a certain test instrument due to the fact that the sample is not dropped uniformly may occur, so that the test result is inaccurate, and the test paper is wasted; and the utility model discloses in, through setting up the project paper piece 200 interval, marked the target point in other words, make the tester conveniently inspect whether waiting to examine the sample among all project paper pieces 200 and drip evenly to guarantee that every project paper piece 200 that needs to detect can not appear missing in the testing process and examine or other inaccurate circumstances of detection take place.
Further, as shown in fig. 1, the item paper block 200 is located between the positioning detection holes 110 at the left and right ends of the test paper substrate 100, so that continuous dropping of the sample to be detected can be ensured in the dropping process, the possibility that the sample to be detected drops on the local part of the test paper tray is reduced, mutual pollution between the samples to be detected is avoided, or stains after drying up hinder normal transportation of other urine analysis test papers.
Further, the test paper substrate 100 for positioning the urine analysis test paper is further provided with a mark part 300, the mark part 300 is arranged on the outermost side of one end of the test paper substrate 100, as shown in fig. 1, a certain distance is arranged between the mark part 300 and the item paper block 200, and the positioning detection hole 110 on the right side of the test paper substrate 100 is arranged between the mark part 300 and the item paper block 200, so that the situation that the mark part 300 is difficult to identify or is polluted due to mistaken dripping on the mark part 300 when a sample to be detected is dripped is avoided.
Further, the marking part 300 is provided with a color different from that of the test paper substrate 100 on the upper side for easy recognition, and the marking part 300 can be recognized by a preset photosensitive sensor, that is, when the test paper substrate 100 is placed in a wrong position up and down or left and right, when the test paper substrate 100 is transported by a test paper tray and passes through the preset photosensitive sensor, the photosensitive sensor cannot recognize the preset color, that is, the test paper substrate 100 is placed in a wrong position, so that alarm correction is performed, and the problem of detection results caused by the wrong placement of the test paper substrate is prevented.
