Abstract
Description
Technical Field
[0001] This application relates to the field of medical testing technology, and in particular to a convenient testing device for reagent test strips. Background Technology
[0002] In medical diagnosis, environmental monitoring, and food safety testing, reagent-based test strips are widely used due to their convenience. For example, in the medical field, common early pregnancy test strips and blood glucose test strips, as well as test strips for water pH and certain pollutants in environmental testing, all provide convenient methods for rapid detection.
[0003] Traditional testing methods mostly involve immersing the test strip in the sample or adding a drop of sample to the test strip, then waiting for the reaction and visually observing the color change of the test strip to determine the result. However, it's difficult to guarantee that the time, method, and amount of contact between the test strip and the sample are completely consistent each time, which may affect the accuracy and repeatability of the test results. Utility Model Content

The reagent adding component includes a dropper located in the bottom box, and an isoelectric tube is provided at the lower end of the dropper. A test strip is also provided in the housing, and the end of the test strip is located in the isoelectric tube.

[0008] Preferably, the upper box includes a detachable upper cover mounted on the bottom shell, the upper cover having an observation port, and the upper end of the drip nozzle passing through the upper cover and flush with the upper surface of the upper cover.
[0009] Preferably, the test strip includes an observation section disposed in the test strip slot, the observation section being located below the observation port, and a drainage section being provided at the end of the observation section.
[0010] Preferably, two scale lines are arranged on the droplet port, the upper scale line is at the same horizontal plane with the observation section, and the lower end of the drainage section is between the two scale lines.
[0011] In summary, the present application has the following beneficial technical effects:
[0012] By using the reagent adding assembly and the test paper, the amount of reagent added can be accurately controlled by using the two scale lines on the droplet port, and the reagent is added to the upper scale line, so that the volume of the reagent for detection is relatively fixed, the error caused by inconsistent addition amount in the traditional detection method is effectively reduced, and the accuracy and repeatability of the detection result are improved. Different from the traditional test paper immersion or sample dropping method, the contact between the equilateral tube and the test paper in this design is fixed, the user only needs to add the reagent into the feeding port, the difference caused by manual operation is reduced, the detection process is more standardized, and the reliability of the detection result is improved. Compared with the prior art, the contact method is standardized, and the detection accuracy is high. BRIEF DESCRIPTION OF DRAWINGS

A test paper card slot is mounted on the end of the bottom shell 101 away from the chamber, the test paper card slot is composed of a plurality of different stoppers 102, which is used to limit and pad the test paper 4.
[0020] With reference to Figure 3 , the test paper 4 comprises an observation section 401 mounted in the test paper card slot, and a drainage section 402 is bent at the end of the observation section 401.

A seat is mounted at the bottom of the chamber to fix the equal position tube 302, so as to prevent the reagent adding assembly 3 from shaking. Two scale lines are provided on the drop port 301, the straight tube end of the drop port 301 has a diameter of 7mm, the distance between the two scale lines is about 4mm, and the volume is about 0.15ml, which is about 3 drops of reagent. The upper scale line is at the same horizontal plane as the observation section 401, and the lower end of the drainage section 402 is located between the two scale lines, and the length of the extension is about 2mm-3mm.
