Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a reagent strip which can be used for transmission colorimetry and scattering colorimetry. Background Art

[0002] At present, colorimetric tubes are used in chemical analysis of samples. The colorimetric tubes after the reaction are photometrically detected by instruments to determine the chemical composition of the samples. Colorimetric tubes are widely used in environmental testing (such as river water quality testing), food quality testing, medical testing or testing in other industries. Portable colorimetric tubes are small in size and can be carried out to test samples on site. They are real-time and convenient.

[0003] In a biochemical analyzer, the reagent strip is used not only for storing reagents, but also for colorimetric function of a reaction cup when used with a biochemical analyzer. The existing analyzer is equipped with a stirrer that extends into the reaction cup for automatic stirring, which increases the equipment cost. In addition, the existing multi-portion reagent bottle is mainly composed of a bottle body and a bottle cap. This type of reagent bottle occupies a large space and has a high processing cost. After the multi-portion reagent bottle is opened for use, the reagent is in contact with the air, and its stability decreases. In view of this, researchers in this field have designed a reagent strip that can be used for transmission colorimetry and scattering colorimetry. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a reagent strip which is easy to use and has high stability and can be used for transmission colorimetry and scattering colorimetry, and the sample and the reagent are mixed evenly by cooperating with the rotating action of the analyzer, so as to facilitate sample addition and colorimetry.

[0005] The technical solution of the utility model is: a reagent strip that can be used for transmission colorimetry and scattering colorimetry, comprising a reagent strip body and a sealing film layer, wherein the sealing film layer is correspondingly covered on the reagent strip body, the reagent strip body comprises a plurality of reagent chambers arranged in parallel, and the two side walls of the reagent chambers are symmetrically provided with mixing slopes inclined inwardly, a mixing colorimetric area is provided between the two slopes, and the middle parts of the mixing slopes on both sides are protruding inwardly and provided with convex rib mixing structures.

[0006] It can be seen from the above scheme that the reagent strip body is used to store multiple reagents through a plurality of reagent chambers, and at the same time has the colorimetric function of a reaction cup. The convex rib mixing structure cooperates with the instrument action to complete the liquid mixing, and the plurality of reagent chambers facilitate the subpackaging of the reagents. The coating layer is used for packaging. The utility model saves space, solves the problem of poor stability of multiple reagents after opening the bottle, and improves the accuracy of the test results. The reagent strip provided by the utility model is a multifunctional reagent strip. In addition to realizing the function of storing the reagents itself, when used with the instrument, it also has the colorimetric function of the reaction cup. Through the convex rib mixing structure and the rotating action of the instrument, it can also complete the mixing of samples and reagents.

[0007] The convex rib mixing structure includes a convex block, an arc portion is provided at the end of the convex block, mixing inclined walls are provided on both sides of the arc portion, and a reaction area is provided between two groups of the mixing inclined walls. It can be seen that the mixing inclined walls are used for the reagent solution and the sample solution to be detected to impact and mix together, and then fall into the mixing colorimetric area to react, which is convenient for subsequent transmission colorimetry or scattering colorimetry.

[0008] The upper surface of the reagent strip body is provided with sealing layer edges protruding toward both sides, and the sealing film layer is correspondingly adhered to the sealing layer edges. It can be seen that the sealing layer edges facilitate the sealing film layer to be more tightly sealed.

[0009] A rectangular area is provided on the sealing film layer, and a barcode is provided on the rectangular area. It can be seen that the barcode on the sealing film layer is used to scan and identify information. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] like Figures 1 to 4As shown, the utility model is a reagent strip that can be used for transmission colorimetry and scattering colorimetry, including a reagent strip body 100 and a sealing film layer 200, the sealing film layer 200 is correspondingly covered on the reagent strip body 100, the reagent strip body 100 includes a plurality of reagent chambers 110 arranged in parallel, the two side walls of the reagent chamber 110 are symmetrically provided with mixing slopes 120 inclined inwardly, a mixing colorimetric area 111 is provided between the two slopes 120, and the middle parts of the mixing slopes 120 on both sides are both protruding inwardly and provided with convex rib mixing structures. In this embodiment, the reagent strip body 100 is arranged in a row and is composed of ten groups of reagent chambers 110, the outer wall of the reagent chamber 110 is provided with an inwardly concave groove corresponding to the convex rib mixing structure, and the reagent strip body 100 is made of plastic material.

[0016] The convex rib mixing structure includes a convex block 300, an arc portion 310 is provided at the end of the convex block 300, and mixing inclined walls 320 are correspondingly provided on both sides of the arc portion 310, and a reaction area 330 is provided between two groups of the mixing inclined walls 320. In this embodiment, the mixing inclined walls 320 are inclined outward from the arc portion 310, the convex block 300 is located in the middle of the mixing inclined surface 120, and the arc portion is convex to the middle of the reagent chamber 110.

[0017] The upper surface of the reagent strip body 100 is provided with sealing edges 130 protruding toward both sides, and the sealing film layer 200 is correspondingly adhered to the sealing edge 130. In this embodiment, the sealing film layer 200 is made of plastic film paper.

[0018] The sealing film layer 200 is provided with a rectangular area 210 , and a barcode is provided on the rectangular area 210 . In this embodiment, the barcode is printed on the rectangular area 210 , and the printed sealing film layer 200 is sealed on the reagent strip body 100 .

[0019] The working process of the utility model is as follows: when performing a colorimetric operation on a reagent strip, the reagent strip is placed in a reaction disk on a biochemical analyzer, and driven by rotation, the reagent solution in the reagent chamber 110 and the dripped sample solution to be tested jointly impact the convex rib mixing structure on the inner walls on both sides, so that the reagent and the sample solution are fully mixed and then reacted, which is convenient for transmission colorimetric operation, increases the mixing effect, and improves the accuracy of the test results.

[0020] When it is necessary to sample the reagent stored in the reagent chamber 110, the sampling needle is inserted into the reagent chamber 110 through the sealing film layer 200 to drip the sample solution to be tested. The operation is simple. When a single reagent chamber is injected with the sample solution, after the end of the reagent strip body 100 is coated and sealed by the sealing film layer 200, the utility model directly pierces the coating layer 200 to enter when in use. Since the pierced pores are small, the reagent in the reagent strip body 100 has less contact with the external air, thereby ensuring the stability of the reagent.

[0021] The reagent strip provided by the utility model is a multifunctional reagent strip, which realizes the function of storing reagents itself and also has the colorimetric function of a reaction cup when used with an instrument. The reagent strip cooperates with the instrument to complete the liquid mixing, and then realizes the colorimetric function through transmission colorimetry or scattering colorimetry. In addition, after the liquid is packaged, the reagent strip is coated and packaged. Compared with the design of a bottle with a screw cap, this reagent strip saves space and is easy to use. It solves the problem of poor stability of common multi-dose reagents in primary medical care after opening the bottle, and saves costs.

[0022] It should be noted that the reagent strip of the present invention is not only used for storing reagents, but can also be used in conjunction with an analytical instrument to perform transmission colorimetry and scattering colorimetry.

[0023] Finally, it should be emphasized that the above is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
