Quantitative detection reagent kit

Abstract

The present invention provides a quantitative detection reagent kit, belonging to the field of detection technology, which includes a kit body, a detection test paper, an absorbent strip, and an end cap. When detecting a sample, the quantitative detection reagent kit of the present invention can be used to sample a sample using a sampling head, and then the end cap can be attached to the end of the kit body. At this time, the sampling head is inserted into the piston cap inside the end cap to mix the sample and the reagent. Then, by inverting the kit body and the end cap (typically, the metering cavity is inverted vertically, with the detection hole located at the bottom), the mixed reagent flows into the metering cavity through the leak hole, and the mixed reagent is brought into contact with the detection test paper at the detection hole for detection. If there is too much liquid in the metering cavity, it will flow out of the metering cavity through the overflow hole at the bottom and be absorbed by the absorbent strip, preventing environmental pollution caused by excessive mixed reagent leaking from the metering cavity.

Description

[Technical Field]

[0001] The present invention is in the field of detection technology, and more particularly relates to quantitative detection reagent kits. [Background technology]

[0002] Fecal hemoglobin, also known as fecal occult blood, is currently considered a tumor marker for rectal and colon cancer in clinical practice and is a very useful diagnostic indicator. Fecal occult blood is an early warning sign of gastrointestinal abnormalities. When the amount of bleeding is small, the appearance of the stool may not change abnormally and may not be discernible with the naked eye. Therefore, the condition of the sample can only be determined after detecting it with a detection reagent. Current detection methods involve sampling the sample with a sampling head, then adding a mixture of the sample and reagent to a test strip for reaction testing. However, many conventional detection reagent kits have the problem of making it difficult to determine the amount of mixture that comes into contact with the test strip during testing. Using too little mixture can affect the test results, while using too much mixture can easily lead to environmental pollution due to sample leakage. Summary of the Invention [Problem to be solved by the invention]

[0007] In one possible implementation, the end of the support partition abuts against the inside of the mounting disc, and the support partition and the mounting disc are of a one-piece structure.

[0008] In one possible implementation, a connecting passage is further installed between the opening of the metering cavity and the leak hole, and the number of the connecting passage is matched with the number of the leak hole.

[0009] In one possible embodiment, a plurality of blocking posts are further installed on the inner wall of the receiving groove, and a blocking post is also installed at the mouth of the connecting passage.

[0016] In order to clarify the technical problem, technical solution and beneficial effects of the present invention, the present invention will be described in more detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are merely for the purpose of illustrating the present invention and are not intended to limit the present invention.

[0017] 1 to 4, the quantitative detection reagent kit provided by the present invention will now be described. The quantitative detection reagent kit includes a kit body 1, a detection test paper 2, a liquid-absorbing strip 3, and an end cap 5. A sampling head 9 and a liquid leakage hole 8 are provided at one end of the kit body 1, and a metering cavity 4 is provided inside. The metering cavity 4 has a first end connected to the liquid leakage hole 8 and a second end provided with a detection hole 401. An overflow hole 402 is provided at the bottom of the metering cavity 4 to prevent excess mixed reagent. The overflow hole 402 is provided at a distance from the detection hole 401. A detection test strip 2 is provided inside the kit body 1 and is arranged along the longitudinal direction of the kit body 1. An end of the detection test strip 2 enters the metering cavity 4 through the detection hole 401. An absorbent strip 3 is provided in the kit body 1 and is arranged at a distance from the detection test strip 2. It is used to absorb and store excess mixed reagent. One end of the absorbent strip 3 enters the metering cavity 4 through the overflow hole 402. An end cap 5 is attached to the end of the kit body 1, and a piston cap is provided inside to store the reagent.

[0018] The quantitative detection reagent kit provided by the embodiment of the present invention differs from the prior art in that it mainly comprises two parts: a kit body 1 and an end cap 5. A sampling head 9 and a leak hole 8 are provided at the end of the kit body 1, and a metering cavity 4 is provided inside the kit body 1. A first end of the metering cavity 4 communicates with the leak hole 8, and a detection hole 401 is provided at the second end. An overflow hole 402 is provided at the bottom of the metering cavity 4 to prevent excess mixed reagent, and the overflow hole 402 is provided at a distance from the detection hole 401. A detection test strip 2 and an absorbent strip 3 are also provided inside the kit body 1. An end of the detection test strip 2 enters the metering cavity 4 through the detection hole 401, and one end of the absorbent strip 3 enters the metering cavity 4 through the overflow hole 402. In the quantitative detection reagent kit provided by the embodiment of the present invention, when sample detection is performed, the end cap 5 can be attached to the end of the kit body 1 after sampling with the sampling head 9. At this time, the sampling head 9 is inserted into the piston cap inside the end cap 5 to mix the sample and reagent, obtaining a mixed reagent, which may be abbreviated as a mixed reagent. Next, by inverting the kit body 1 and the end cap 5 (generally, the metering cavity 4 is inverted vertically, with the detection hole 401 located at the bottom), the mixed reagent flows into the metering cavity 4 through the liquid leakage hole 8, and the mixed reagent is brought into contact with the detection test paper 2 at the detection hole 401 for detection. If there is too much liquid in the metering cavity 4, it will flow out of the metering cavity 4 through the overflow hole 402 on the bottom surface of the metering cavity 4 and be absorbed by the liquid-absorbing strip 3, preventing environmental pollution caused by leakage of too much mixed reagent from the metering cavity 4.

[0019] The bottom of the metering cavity 4 referred to here refers to the positional relationship when the kit body 1 is placed horizontally; it is merely a nomenclature limitation and does not specify orientation. When performing a measurement, the kit body 1 is generally inverted to a vertical position, and at this time, the bottom of the metering cavity 4 is in a vertical position. The overflow hole 402 and the detection hole 401 are spaced apart, and the maximum capacity of the metering cavity 4 can be controlled by the distance between the overflow hole 402 and the detection hole 401. The control piston cap is fitted into the end cap 5, and a reagent is sealed inside the piston cap. An aluminum plastic film covers the opening of the piston cap to seal it. After the sampling head 9 pierces the aluminum plastic film, the sample and reagent are mixed. The absorbent strip 3 is generally made of an absorbent material, such as absorbent paper or a cotton strip, and is fixed inside the kit body 1.

[0020] 2 and 3, a support partition plate 6 is further installed inside the kit body 1, the detection test strips 2 and the liquid-absorbent strips 3 are installed on both sides of the support partition plate 6, and the metering cavity 4 and the detection test strips 2 are installed on the same side of the support partition plate 6. Specifically, the support partition plate 6 is installed along the axial direction of the kit body 1, dividing the interior of the kit body 1 into two independent regions. The installation of the support partition plate 6 can separate the detection test strips 2 and the liquid-absorbent strips 3, preventing overflowing waste liquid from interfering with the detection of the detection test strips 2 and making it easier to install the detection test strips 2 and the liquid-absorbent strips 3. The metering cavity 4 is formed by surrounding a retaining wall installed on the side of the support partition plate 6 (the retaining wall is generally integrally injection molded with the support partition plate 6), and in this case, the bottom of the metering cavity 4 is the side of the support partition plate 6. The top opening of the metering cavity 4 may be sealed by abutting against the inner wall of the kit body 1, or may be sealed by covering the top opening of the metering cavity 4 with a metering reservoir cap plate, which is also generally made of an absorbent material, such as absorbent paper or absorbent cotton.

[0021] 2 and 3, to facilitate the mixed reagent flowing into the metering cavity 4, an opening is provided at the end of the kit body 1, a mounting disc 7 is further provided at the end of the kit body 1, a receiving groove is further provided on the outer surface of the mounting disc 7, and a sampling head 9 and a liquid leakage hole 8 are both located at the bottom of the receiving groove. Specifically, one end of the sampling head 9 is fixedly mounted at the bottom of the receiving groove and the other end extends away from the end of the kit body 1, the sampling head 9 is located at the center of the receiving groove, and the liquid leakage holes 8 are located on both sides of the sampling head 9, making the overall assembly easier.

[0022] Preferably, an observation hole is further installed on the side of the kit body 1 for observing the display result of the detection test paper 2, which makes it easier to observe the detection result, and the bottom surface of the receiving groove can be configured with two inclined surfaces forming an angle with each other, which can facilitate the mixed reagent to enter the inside of the metering cavity 4 through the liquid leakage hole 8 located at the bottom of the receiving groove after the kit body 1 becomes vertical, making the measurement easier and faster.

[0023] As shown in Figure 4, the end of the support partition plate 6 abuts against the inside of the mounting disc 7, and the support partition plate 6 and the mounting disc 7 are formed as an integral structure. Specifically, the support partition plate 6 and the mounting disc 7 are formed as an integral structure, and the stopper wall surrounding the metering cavity 4 on the side of the support partition plate 6 can be directly connected to the side of the mounting disc 7, preventing leakage of the mixed reagent due to a gap between the metering cavity 4 and the liquid leakage hole 8, making sample detection safer.

[0024] In addition, the kit body 1 generally adopts a separate structure, and for example, when the kit body 1 is positioned horizontally, the kit body 1 can be divided into an upper housing and a lower housing, and the support partition plate 6 and the mounting plate 7 can be installed between the upper housing and the lower housing, making installation easier.

[0025] 3 and 4, a connecting passage 10 is further installed between the opening of the metering cavity 4 and the leaking holes 8, and the number of the connecting passages 10 corresponds to the number of the leaking holes 8. Specifically, the installation of the connecting passage 10 can delay the time it takes for the mixed reagent to flow into the metering cavity 4, making the operation easier. Moreover, the installation of the connecting passage 10 can make the location of the metering cavity 4 more flexible.

[0026] Preferably, as shown in Figure 4, a plurality of blocking columns are further installed on the inner wall of the receiving groove, and a blocking column is also installed at the mouth of the connecting passage 10. Specifically, the blocking columns are installed at intervals on the inner wall of the receiving groove and at the mouth of the connecting passage 10 to block foreign matter in the sample and prevent the foreign matter from entering the metering cavity 4 and thereby affecting the detection results of the detection test strip 2.

[0027] 4, in some possible implementations, the first end of the metering cavity 4 is tapered, the detection hole 401 is located at the tapered end, a liquid stopper is further located at the detection hole 401, and both ends of the liquid stopper are located at a distance from the inner wall of the metering cavity 4. Specifically, the first end of the metering cavity 4 is tapered, which makes it easier for the mixed reagent to flow and concentrate at the detection hole 401 after the kit body 1 is inverted and turned vertically, and the installation of the liquid stopper can prevent a large amount of liquid from suddenly gushing into the detection hole 401 and leaking, thereby ensuring the accuracy of the measurement.

[0028] 4, the bottom surface of the metering cavity 4 is inclined, and the inclined surface slopes from the first end to the second end of the metering cavity 4. Specifically, the overflow hole 402 is located on the inclined surface, and the bottom surface of the metering cavity 4 is inclined, which makes it easier for the mixed reagent to concentrate in the detection hole 401.

[0029] 3, a fastening structure 11 for connecting the kit body 1 and the end cap 5 to each other is further provided between the end of the kit body 1 and the end cap 5. Specifically, the provision of the fastening structure 11 can improve the sealing performance between the kit body 1 and the end cap 5, and can prevent leakage of the mixed reagent when the kit body 1 is inverted.

[0030] The characteristic fastening structure 11 described above employs a structure as shown in Fig. 3. Referring to Fig. 3, the fastening structure 11 includes a mounting convex ring 111 mounted on the end of the kit body 1 and abutting against the inner wall of the end cap 5, a fastening protrusion 112 mounted on the inner wall of the end cap 5, and a fastening groove mounted on the outside of the mounting convex ring 111. When the end cap 5 is mounted, the outer wall of the mounting convex ring 111 abuts against the inner wall of the end cap 5 to form a tight seal, and the fastening protrusion 112 is engaged in the fastening groove to prevent the end cap 5 and the mounting convex ring 111 from coming apart, ensuring a tight and strong connection between them and providing a better seal.

[0031] The above are merely preferred embodiments of the present invention, and are not intended to limit the present invention. All modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included within the protection scope of the present invention.

[Industrial Applicability]

[0048] Compared with the prior art, the quantitative detection reagent kit provided by the embodiment of the present invention mainly comprises two parts: a kit body and an end cap. The end of the kit body is provided with a sampling head and a leak hole, and the inside of the kit body is provided with a metering cavity, with a first end of the metering cavity connected to the leak hole and a second end with a detection hole.

When detecting a sample, the quantitative detection reagent kit provided by the embodiment of the present invention can be used to detect a sample by using the sampling head, and then the end cap can be attached to the end of the kit body. At this time, the sampling head is inserted into the piston cap inside the end cap to mix the sample and the reagent. Next, by inverting the kit body and end cap (generally, the metering cavity is inverted vertically and the detection hole is located at the bottom), the mixed reagent flows into the metering cavity through the liquid leakage hole, and the mixed reagent is brought into contact with the detection test paper in the detection hole for detection. If there is too much liquid inside the metering cavity, it will flow out of the metering cavity through the overflow hole on the bottom of the metering cavity and be absorbed by the liquid-absorbing strip, preventing environmental pollution caused by leakage due to too much mixed reagent in the metering cavity.
