Description

Technical Field

[0001] This utility model relates to the field of diagnostic testing technology, specifically a homocysteine ​​detection kit. Background Technology

[0002] Homocysteine ​​(Hcy) is an independent risk factor for cardiovascular and cerebrovascular diseases, stroke, cognitive impairment, and pregnancy complications, making its clinical detection crucial. Common detection methods include enzyme cycling, fluorescence, and chromatography, with enzyme cycling being widely used due to its simplicity and high sensitivity.

[0003] Existing enzymatic Hcy detection kits typically contain multiple reagent bottles (such as R1 reagent, R2 reagent, calibrators, etc.). These reagent bottles are individually packaged, requiring manual opening, aspiration, and transfer multiple times during use. This can easily increase the complexity of the operation, cause cross-contamination, and lead to errors. To address this, this technical solution designs a homocysteine ​​detection kit. Utility Model Content

[0004] The purpose of this invention is to provide a homocysteine ​​detection kit to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a homocysteine ​​detection kit, comprising a kit, a base, and a top cap; The reagent kit has multiple reagent compartments arranged in a ring in the middle. The reagent compartment is provided with pre-set channels at the top; The reagent kit has a lifting channel at its center, and a lifting puncture component is installed inside it. The puncture assembly includes a puncture plate and a puncture needle connected thereto, the puncture needle corresponding to a pre-set channel position.

[0006] Preferably, the puncture assembly further includes a spring elastically connected in the lifting channel, a spring plate fixing the top of the spring, a connecting rod connecting the spring plate and the puncture plate, and a pressing block disposed on the top of the puncture plate.

[0007] Preferably, the pre-formed channel is made of an easily puncturable sealing material, including a rubber stopper or a foil film.

[0008] Preferably, the reagent kit has at least one external detection tool storage compartment on its circumferential outer wall, which has a foam board adapted to the detection tool inside, and a door is hinged to one side of the external detection tool storage compartment.

[0009] Preferably, the reagent kit has an I-shaped structure with a box opening at the top that extends downwards to the upper part of the reagent compartment.

[0010] Preferably, the reagent compartment has an arc-shaped cross-section.

[0011] Preferably, the reagent kit, base, and top cover are made of a light-proof material.

[0012] Compared with the prior art, the beneficial effect of this utility model is that all reagent compartments can be opened simultaneously by pressing a single point, avoiding multiple openings; The pre-formed channels are sealed until use, and the liquid is extracted directly after the puncture needle punctures the channels, thus preventing cross-contamination. The integrated design of the external testing tool storage compartment and reagent compartment reduces the risk of tool loss; The I-shaped base structure and spring-driven automatic reset design ensure reliable operation. The box is made of light-proof material and has a sealed structure to ensure the long-term stability of reagents during storage. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 A homocysteine ​​detection kit includes a kit 10. Within the kit 10, multiple reagent compartments 15 are formed by a series of equally spaced, ring-shaped partitions. Each reagent compartment 15 stores different types of detection reagents, such as: Reagent R1: R1's main function is to dilute the sample and provide an optimal reaction environment; its main components include a buffer system, reducing agent, coenzyme / substrate, and stabilizer. Reagent R2: Contains a core enzyme system used to initiate an efficient enzyme cycle reaction and generate a detectable signal; its main components include the core enzyme system (Hcy-specific enzyme, SAH methyltransferase, coupled indicator enzyme, etc.), signal detection-related substances, etc.; calibrators, quality control materials, etc. The reagent compartment 15 has a sealed top and a pre-placed channel 18. The pre-placed channel 18 is made of an easily puncturable sealing material. The reagent compartment 15 has an arc-shaped cross-section. A lifting channel 16 with a top opening is opened on the upper side of the center of the reagent kit 10. A set of puncture components is elastically installed inside the lifting channel 16. The puncture components are raised and lowered by manual pressing, and then cooperate with the pre-placed channel 18 on the top of each reagent compartment 15 to realize the synchronous puncture and opening of the pre-placed channel 18. This enables the reagent kit 10 to store and open and retrieve individual test reagents simultaneously.

[0023] In embodiments of the present invention, easily puncturable sealing materials typically include rubber stoppers, tin foil films, etc. The reagent kit 10 is designed with an "I"-shaped structure. It has a base 11 at the bottom to increase the stability of placement and a top cover 12 at the top. The top cover 12 has a box opening 13 in the middle. The bottom of the box opening 13 extends downward to the upper part of the reagent compartment 15, thus maintaining sufficient operating space in the upper part of the reagent compartment 15. The puncture component can move freely up and down along this operating space, and space is provided for the entry and exit of external tools.

[0024] In one embodiment of the present invention, at least one external detection tool storage compartment 14 is uniformly provided on the outer wall of the reagent kit 10. A door is hinged to one side of the external detection tool storage compartment 14. A foam board is provided inside the external detection tool storage compartment 14. The shape of the foam board is set according to the shape of the detection tool to be stored, that is, to ensure that the detection tool can be stably positioned inside the external detection tool storage compartment 14. The testing tools include sample dilution cups, quantitative pipettes, and pipettes. The materials of reagent kit 10, base 11, and top cover 12 can be selected from plastic, glass, etc., according to requirements. At the same time, according to the storage requirements of the test reagent, it is designed to protect it from light, that is, to prevent it from being exposed to strong external light when it is stored, which may cause it to deteriorate.

[0025] In a preferred embodiment of the present invention, the puncture assembly includes a spring 19 elastically connected inside the lifting channel 16. A connecting rod 21 is mounted on the top of the spring 19 via a spring plate 20. A puncture plate 22 is mounted on the top center of the connecting rod 21. A puncture plate 24 is mounted on the bottom of the puncture plate 22 at the position corresponding to the pre-set channel 18 on the top of each reagent chamber 15. A pressing block 23 is mounted on the top center of the puncture plate 22. When the spring 19 is in a free state, the control 24 is moved away from the pre-set channel 18. When it is necessary to detect and take the reagent inside the reagent chamber 15, the pressing block 23 is manually pressed downward, and then the control 24 is simultaneously brought into contact with the corresponding lower pre-set channel 18 to puncture it, thereby opening the top of the reagent chamber 15. Then, the liquid is taken out through an external suction tube or other tools.

[0026] The working principle of this utility model is as follows: the pre-set channels 18 at the top of each reagent compartment 15 are sealed by rubber plugs / tin foil film of easily puncturable material. The puncture component is in a high position under the action of spring 19, and the puncture needle 24 is away from the pre-set channels 18. The user presses the pressing block 23 at the top of the puncture plate 22, pushes the connecting rod 21 down, and the puncture plate 22 drives the puncture needles 24 of the ring array to press down synchronously, puncturing the pre-set channels 18 of all reagent compartments 15. Spring 19 stores energy under pressure, and spring plate 20 provides downward momentum cushioning.

[0027] After puncture, the external suction tube is inserted into the reagent compartment 15 through the box opening 13 to directly draw out reagents such as R1 and R2.

[0028] Reset and protection: After releasing the pressing block 23, the spring 19 pushes the spring plate 20 upward, causing the puncture needle 24 to exit the reagent chamber 15; When the top cover 12 is closed, the opening 13 of the box is covered to prevent contaminants from entering.

[0029] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
