[0028] In view of the problems in the prior art that the sampling device is relatively large in volume, prone to bending and entering the sample, and the applicable detection methods are single, etc., the present utility model provides a brand-new reagent kit, which changes the traditional liquid addition mode and sampling method, integrates liquid addition and sampling, and realizes that the sampling needle can be folded and stored through the structure, automatically punctures the reagent seal, greatly reduces the packaging volume, and is convenient for customers to use; the test kit integrates chromatography and turbidimetry, greatly increasing the applicable range of test items. The following describes the present utility model with specific embodiments.

[0029] Embodiment 1

[0030] Please refer to Figures 1 to 3 , Embodiment 1 provides a reagent kit, which includes a reagent storage component and a reaction cavity component. The reaction cavity component includes a first chamber 10, a second chamber 9, and a third chamber 11. The first chamber 10 is used to receive a first reagent and a sample, and provides a reaction site for the first reagent and the sample. The second chamber 9 communicates with the first chamber 10 and is used to receive a second reagent. The third chamber 11 communicates with the first chamber 10 and is used to flow the reaction liquid in the first chamber 10 into the third chamber 11. The first chamber 10 is locally communicated with the second chamber 9 and the first chamber 10 is locally communicated with the third chamber 11 in a common cutting plane direction. The reaction cavity component can be rotated to move the first reagent, the second reagent and the sample between the first chamber 10 and the second chamber 9, and the first chamber 10 and the third chamber 11; as Figure 4 shown.

[0031] The reagent storage component includes a first reagent accommodating chamber 1 for storing a first reagent and a second reagent accommodating chamber 2 for storing a second reagent. The reaction chamber component is provided with a first puncturing needle and a second puncturing needle respectively opposite to the first reagent accommodating chamber 1 and the second reagent accommodating chamber 2. The reagent storage component can be inserted into the reaction chamber component. When the reagent storage component is inserted into the reaction chamber component, the first puncturing needle and the second puncturing needle puncture the sealing parts of the first reagent accommodating chamber 1 and the second reagent accommodating chamber 2 and insert into the first reagent accommodating chamber 1 and the second reagent accommodating chamber 2, so that the first reagent and the second reagent flow into the first chamber 10 and the second chamber 9 respectively.

[0032] In the kit of this embodiment, the first chamber 10 and the second chamber 9, and the first chamber 10 and the third chamber 11 are not completely connected, nor are they completely separated, but are partially connected. It can be understood that the connecting part of the two chambers that need to be connected is on the common section plane of the two chambers. In this way, it not only ensures that the liquids in each chamber will not be mixed with each other, but also can be smoothly mixed when the liquids in the two chambers need to be mixed. The liquid here can be a certain reagent, or a mixed liquid after mixing or chemical reaction of multiple reagents, etc.

[0033] For the convenience of detection, the first chamber 10 is provided with a first detection port, the third chamber 11 is provided with a second detection port, and the third chamber 11 is separated into a detection chamber and a waste liquid chamber through the second detection port, and the detection chamber is communicated with the second chamber 9.

[0034] The reaction chamber component is provided with a card slot 14, and the reagent storage component is provided with a clamping part 13 for locking with the reaction chamber component. The reaction chamber component is provided with a positioning rod 16, and the reagent storage component is provided with a positioning groove 15. When the reagent storage component is inserted into the reaction chamber component, the positioning cylinder is inserted into the positioning groove 15.

[0035] In order to prevent the puncturing needle 5 from causing partial or complete blockage of the puncture port, which is not conducive to the outflow of the reagent. In some embodiments, the first puncturing needle and the second puncturing needle are of a hollow structure, which allows the first reagent and the second reagent to flow out smoothly. When the reagent flows out from the puncture port, it can also flow out from the hollow hole in the middle of the puncturing needle 5, saving time.

[0036] Furthermore, in order to improve the storage convenience and use convenience of the kit, the reagent storage component further includes a sampling part. The sampling part includes a sampling arm 3 and a sampling needle 4 provided at the end of the sampling arm 3. The sampling needle 4 can sample by the siphon principle. The sampling arm 3 is located on the side of the reagent storage component and can rotate 180° along the insertion direction of the reagent storage component.

[0037] When not in use, the sampling arm 3 can be rotated so that the sampling needle 4 faces upward, which is convenient for storage. When in use, the sampling arm 3 is rotated so that the sampling needle 4 faces vertically downward. As shown in Figure 1 , the sampling needle 4 is brought close to the sample, and sampling is carried out by the siphon principle. After sampling is completed, it is inserted into the reaction cavity component. The reaction cavity component locks the reagent pack through an inverted buckling device. After the test is completed, it is disposed of as medical waste together. The reaction cavity component forms different flow channels through an intermediate partition to separate the reagents. The puncturing needle 5 includes a first puncturing needle and a second puncturing needle. The first puncturing needle punctures the sealing films of the first reagent accommodating cavity 1 and the second reagent accommodating cavity 2. The first reagent flows into the first chamber 10 through the hole in the middle of the first puncturing needle and is mixed with the sample. The second reagent flows into the second chamber 9 through the hole in the middle of the second puncturing needle. After shaking the reaction cavity component to make the first reagent and the sample react completely, the second reagent is added to the first chamber 10 by rotation and mixed. If the instrument determines that turbidimetry test is required, the test will be directly carried out through the optical path at the first test port 6. After the test is completed, the reaction cavity component is rotated to drain the waste liquid into the third chamber 11. An absorbent material 7 is provided in the waste liquid chamber of the third chamber 11, which can be any material with strong water absorption such as sponge, cotton, paper, gel, etc. If the instrument determines that chromatography test is required, the reaction cavity component will be rotated to make the reacted reagent flow through the second test port 8 into the absorbent cotton in the third chamber 11, so as to leave the microspheres used for the test to fill the second test port 8. The instrument judges the measured value of the sample according to the different degrees of reflection of the microspheres.

[0038] Furthermore, when the waste liquid flows into the waste liquid chamber, if the waste liquid chamber is sealed, the discharge of the waste liquid will inevitably cause the air in the waste liquid chamber to be squeezed, and the waste liquid is mostly various chemical substances after chemical reactions and may continue to react. This phenomenon will be more serious for waste liquids that generate gas. In order to prevent the air pressure in the waste liquid chamber from rising and causing the waste liquid to not be discharged, the reaction cavity component further includes a fourth chamber 12, and the fourth chamber 12 is communicated with the waste liquid chamber for discharging the air in the waste liquid chamber into the fourth chamber 12.

[0039] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
