Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a lateral flow chromatography diagnostic product for early pregnancy and ovulation. Background Art

[0002] Early pregnancy and ovulation test kits are diagnostic products used to detect early pregnancy in women. They measure the concentration of HCG (human chorionic gonadotropin) in the urine of pregnant women to confirm pregnancy. Ovulation test kits measure the concentration of LH in urine, and the LH concentration on the test strip determines whether a woman is in the optimal ovulation period.

[0003] For user convenience, pregnancy and ovulation test kits are typically designed to be loaded directly with urine, eliminating the need for a urine cup or straw, making the test more convenient and hygienic. However, to ensure that the test strips within the pregnancy test kit are loaded with urine evenly, stably, and in sufficient amounts during the test, a nylon fiber absorbent element is installed at the front of the test kit. This absorbent element absorbs large amounts of urine in a short period of time and ensures that the urine is transferred to the test strips at a uniform and stable flow rate.

[0004] However, the absorbent components of typical pregnancy and ovulation lateral flow diagnostic products are limited in size and cannot absorb large amounts of urine at once. Therefore, the user must hold the pregnancy and ovulation test pen in a raised position and continuously allow urine to flow onto the front absorbent component for approximately 20 seconds. This ensures that sufficient HCG or LH is present on the test strip to bind to latex antibodies and form a test line. If sample loading is interrupted or insufficient during the test, insufficient binding of HCG or LH to latex antibodies can affect the accuracy of the test results, potentially leading to errors. Utility Model Content

[0005] In order to solve the above problems, the utility model proposes an accessory structure that meets the needs of rapid sampling of early pregnancy and ovulation detection pens, which can transport HCG or LH hormones in urine to the test line on the test paper at a uniform and stable chromatography speed, and combine with the latex antibodies therein to present stable test results.

[0006] To achieve the above purpose, the present invention proposes:

[0007] An accessory structure that meets the needs of rapid sample loading for early pregnancy and ovulation test pens includes a test pen body with a accommodating cavity formed inside the test pen body. One end of the test pen body is a liquid inlet end, and a plurality of liquid inlet holes are opened on both sides of the liquid inlet end. The liquid inlet holes are interconnected with the accommodating cavity, and the plurality of liquid inlet holes form a honeycomb structure.

[0008] Preferably, the accommodating chamber inside the detection pen body consists of two parts, namely a first accommodating chamber and a second accommodating chamber, and the first accommodating chamber and the second accommodating chamber are interconnected.

[0009] Preferably, the first accommodating cavity accommodates a water absorbing member, and the second accommodating cavity accommodates a test paper.

[0010] Preferably, the liquid inlet end corresponds to the position of the first accommodating cavity.

[0011] Preferably, the detection pen body is provided with a first window at one end where the second accommodating cavity is provided, and the first window is communicated with the second accommodating cavity.

[0012] Preferably, the detection pen body is further provided with a second window at one end where the second accommodating cavity is provided, and the second window is communicated with the second accommodating cavity.

[0013] Preferably, a raised portion is provided at the middle position of the detection pen body.

[0014] Preferably, the detection pen body consists of a first cover body and a second cover body connected to the first cover body, the first cover body is provided with a plurality of jacks along the outer peripheral side, the second cover body is provided with a plurality of plugs along the outer peripheral side, and the plugs are adapted to the jacks.

[0015] Preferably, the liquid inlet holes are respectively provided on the same end of the first cover body and the second cover body.

[0016] Preferably, the first window and the second window are provided on the other end of the second cover.

[0017] Beneficial effects of the utility model:

[0018] The structure of the utility model is simple. When testing, the user only needs to pour urine on the honeycomb structure at the front end of the test pen to complete the sampling. The liquid inlet end is provided with a liquid inlet hole, through which the urine to be tested can enter the receiving chamber. The first cover, the second cover and the water absorbent cooperate with each other to form a space that can store a sufficient amount of urine (a large amount of urine can be stored in this space by utilizing the tension of water). The urine is continuously provided to the test paper for absorption, and the HCG or LH hormone in the urine is transported to the test line on the test paper and combined with the latex antibody therein until the test is completed and a stable and reliable test result line is displayed.

[0019] This design can avoid inaccurate or erroneous test results caused by urine sampling interruption or insufficient sample volume due to user misoperation, reduce the difficulty of user test pen operation, and improve the accuracy and stability of chromatographic diagnostic products.

[0028] Please refer to Figure 1-3 An accessory structure that meets the needs of rapid sample loading for early pregnancy and ovulation test pens includes a test pen body 1. The test pen body 1 is composed of a first cover body 11 and a second cover body 12 connected to the first cover body 11. A accommodating cavity is formed inside the test pen body 1, that is, the accommodating cavity is formed by the first cover body 11 and the second cover body 12 covering and enclosing each other. One end of the test pen body 1 is a liquid inlet end 2, and the liquid inlet end 2 is recessed inward to prevent urine turbulence. A plurality of liquid inlet holes 3 are provided on both sides of the liquid inlet end 2. The liquid inlet holes 3 include a majority of hexagonal liquid inlet holes 3 and a minority of circular center liquid inlets. The liquid inlet holes 3 are interconnected with the accommodating cavity. The plurality of liquid inlet holes 3 form a honeycomb structure. The tension of the liquid can be used to lock urine at the position of the liquid inlet hole 3, thereby increasing the running speed of the liquid and increasing the testing efficiency of the liquid.

[0029] Furthermore, the accommodating chamber inside the detection pen body 1 is composed of two parts, namely a first accommodating chamber 4 and a second accommodating chamber 5. The first accommodating chamber 4 and the second accommodating chamber 5 are interconnected, wherein the first accommodating chamber 4 accommodates a water-absorbing component 6, and the second accommodating chamber 5 accommodates a test paper 7. The water-absorbing component 6 and the test paper 7 are pressed into the first accommodating chamber 4 and the second accommodating chamber 5 by the covering of the first cover body 11 and the second cover body 12.

[0030] In this embodiment, the absorbent member 6 is absorbent cotton, and the test paper 7 is HCG or LH detection test paper 7.

[0031] Furthermore, the position of the liquid inlet end 2 corresponds to that of the first accommodating chamber 4 .

[0032] Furthermore, the detection pen body 1 is provided with a first window 9 at one end where the second accommodating cavity 5 is provided. The first window 9 is communicated with the second accommodating cavity 5. The first window 9 is an observation window. The user can observe the color change of the test line of the test paper 7 through the first window 9 to obtain the test result.

[0033] Furthermore, the detection pen body 1 is provided with a second window 10 at one end where the second accommodating chamber 5 is provided. The second window 10 is communicated with the second accommodating chamber 5. The second window 10 is an anti-siphon window that prevents liquid siphoning.

[0034] Furthermore, a raised portion 8 is provided at the middle position of the detection pen body 1 , and the raised portion 8 acts as a partition to prevent urine from flowing along the outer wall of the detection pen body 1 to the other end.

[0037] Furthermore, the first window 9 and the second window 10 are provided on the other end of the second cover 12 .

[0038] The present invention provides an accessory structure that facilitates rapid sample loading for early pregnancy and ovulation test pens. Through precise mold forming, a stable space capable of storing urine is formed between the test pen body 1 and the absorbent element 6. When a user uses the test pen, the moment urine is deposited on the honeycomb structure at the front end of the test pen, the urine is stored in the space between the test pen body and the absorbent element 6 (the capacity of this space is determined through testing and calculation, and the stored liquid is sufficient to transport the HCG or LH hormones in the urine to the test line on the test paper 7 at a uniform and stable chromatography rate, where they bind to the latex antibodies present therein, resulting in a stable test result line). The urine is then transferred to the test paper 7 via the absorbent element 6 for reaction.
