Description

Technical Field

[0001] This utility model belongs to the field of luteinizing hormone detection technology, specifically relating to luteinizing hormone (LH) test strips. Background Technology

[0002] CN 203551569 U, entitled "A Combined Detection Kit for Luteinizing Hormone and Urinary Tract Infection", includes a first substrate (10), a chromatography membrane (6) disposed on one side of the first substrate (10), an opaque protective membrane (3) disposed at the front end of the chromatography membrane (6), an arrow (2) disposed at the front end of the opaque protective membrane (3); a conjugate pad (1) disposed at the front end of the arrow (2); a detection line (4) and a control line (5) are also disposed sequentially on the chromatography membrane (6), and an absorbent pad (7) is disposed at the rear end of the chromatography membrane (6). It also includes an infection indicator detection area (8). The infection indicator detection area (8) is attached to a second substrate (11) or composite to any surface of the first substrate (10). A luteinizing hormone and urinary tract infection detection kit includes a first substrate (10), a chromatography membrane (6) is disposed on one side of the first substrate (10), a conjugate pad (1) is disposed at the front end of the chromatography membrane (6), and a sample pad (9) is disposed in front of the conjugate pad (1); a detection line (4) and a quality control line (5) are disposed sequentially on the chromatography membrane (6), and an absorbent pad (7) is disposed at the rear end of the chromatography membrane (6); an infection indicator detection area (8) is disposed on the lower surface of the first substrate (10). Its shortcomings are as follows: In this luteinizing hormone and urinary tract infection combined test kit, the luteinizing hormone test strip has an absorbent pad attached to one end of the chromatographic membrane (reaction pad). Since the effective absorption of the absorbent pad (sample solution from the sample pad, conjugate pad, etc.) relies on the effective contact area between the absorbent pad and the reaction pad, the luteinizing hormone test strip with the absorbent pad attached to the reaction pad has a relatively high failure rate (there are relatively many products where the test line (T line) and the control line (C line) are not colored or have a faint color). Utility Model Content

[0003] Design objective: To overcome the shortcomings of the prior art, this paper designs a luteinizing hormone (LH) test strip that not only reduces the failure rate of the LH test strip but also has good performance.

[0004] Design scheme: To achieve the above design objectives.

[0005] 1. The outer casing has a sample solution window on one side of its upper surface and an observation window on the other side of its upper surface. A test strip is located inside the outer casing, and the reaction pad in the test strip has a luteinizing hormone (LH) detection line and a LH control line. The sample pad in the test strip faces the sample solution window, and both the LH detection line and the LH control line face the observation window. The test strip is characterized by comprising a substrate, a sample pad, a conjugate pad, a reaction pad, a first absorbent pad, and a second absorbent pad. The substrate is composed of a sample pad, a bonding pad, a reaction pad, and a first absorbent pad on its upper surface. The lower surface of one end of the sample pad overlaps with the upper surface of one end of the bonding pad, the lower surface of the other end of the bonding pad overlaps with the upper surface of one end of the reaction pad, and the lower surface of the other end of the reaction pad overlaps with the upper surface of one end of the first absorbent pad. The upper surface of the first absorbent pad is provided with a second absorbent pad, and the lower surface of one end of the second absorbent pad overlaps with the upper surface of the corresponding end of the reaction pad. This design is one of the technical features of this utility model. The purpose of this design is as follows: a sample liquid window is provided on one side of the upper surface of the outer shell, and an observation window is provided on the other side of the upper surface of the outer shell. A test strip is provided inside the outer shell, and the reaction pad in the test strip has a luteinizing hormone (LH) detection line and a LH control line. The sample pad in the test strip faces the sample liquid window, and both the LH detection line and the LH control line face the observation window. The test strip is characterized by being composed of a substrate, a sample pad, a conjugate pad, a reaction pad, a first absorbent pad, and a second absorbent pad. The upper surface of the substrate has the sample pad, conjugate pad, reaction pad, and first absorbent pad. The lower surface of one end of the sample pad is connected to the conjugate pad... The upper end face of the first absorbent pad overlaps with the upper end face of the other end of the first absorbent pad, and the lower end face of the other end of the first absorbent pad overlaps with the upper end face of the first absorbent pad. The upper end face of the first absorbent pad is provided with a second absorbent pad, and the lower end face of one end of the second absorbent pad overlaps with the upper end face of the corresponding end of the reaction pad. Since both the first absorbent pad and the second absorbent pad overlap with the reaction pad, the effective contact area between the absorbent pad and the reaction pad is greatly increased, thereby reducing the failure rate of the luteinizing hormone test strip. In addition, the second absorbent pad is located on the upper end face of the first absorbent pad, so it will not increase the area required for the luteinizing hormone test strip.

[0006] 2. The sample pad is composed of a first sample pad layer and a second sample pad layer. The upper surface of the first sample pad layer is provided with the second sample pad layer. The upper surface of the second sample pad layer is provided with multiple through holes that penetrate both the upper and lower surfaces of the second sample pad layer. The design of the lower surface of one end of the first sample pad layer overlapping the upper surface of one end of the conjugate pad is the second technical feature of this utility model. The purpose of this design is that the sample pad is composed of a first sample pad layer and a second sample pad layer. The upper surface of the first sample pad layer is provided with the second sample pad layer. The upper surface of the second sample pad layer is provided with multiple through holes that penetrate both the upper and lower surfaces of the second sample pad layer. The lower surface of one end of the first sample pad layer overlaps with the upper surface of one end of the conjugate pad. The upper surface of the second sample pad layer is provided with multiple through holes. The through holes can prevent the sample liquid dripping through the sample liquid window from splashing, thereby improving the usability of the luteinizing hormone (LH) test strip.

[0007] 3. The design of the outer shell, consisting of an upper shell and a lower shell that can interlock, is the third technical feature of this utility model. The purpose of this design is that the outer shell, consisting of an upper shell and a lower shell that can interlock, facilitates the production and assembly of the luteinizing hormone (LH) test strip.

[0008] Technical Solution: A luteinizing hormone (LH) test strip includes a test strip and a housing. One side of the upper surface of the housing has a sample window, and the other side has an observation window. The housing contains the test strip, and the reaction pad within the test strip has a luteinizing hormone detection line and a luteinizing hormone quality control line. The sample pad in the test strip faces the sample window, and both the luteinizing hormone detection line and the luteinizing hormone quality control line face the observation window. The test strip consists of a substrate, a sample pad, and a reaction pad. The substrate comprises a sample pad, a bonding pad, a reaction pad, a first absorbent pad, and a second absorbent pad. The upper surface of the substrate is provided with the sample pad, the bonding pad, the reaction pad, and the first absorbent pad. The lower surface of one end of the sample pad overlaps with the upper surface of one end of the bonding pad. The lower surface of the other end of the bonding pad overlaps with the upper surface of one end of the reaction pad. The lower surface of the other end of the reaction pad overlaps with the upper surface of one end of the first absorbent pad. The upper surface of the first absorbent pad is provided with the second absorbent pad, and the lower surface of one end of the second absorbent pad overlaps with the upper surface of the corresponding end of the reaction pad.

[0009] Compared with the prior art, the luteinizing hormone (LH) test strip of this invention can not only reduce the failure rate of luteinizing hormone test strips, but also has a better effect. Attached Figure Description
