[0031] Embodiments of the present application are described below with reference to the accompanying drawings.

[0032] Embodiments of the present application are described below with reference to the accompanying drawings.

[0033] One embodiment of the present application relates to a reagent cartridge 100. As shown in Figure 1 and Figure 2 The reagent cartridge 100 includes a cartridge body 1 having a plurality of chambers 10 extending through the cartridge body 1, each chamber 10 being configured to inject a fluid. The chamber 10 has an outlet end 11 formed at the bottom of the cartridge body 1. The cartridge body 1 can be cylindrical, and the chamber 10 extends through the cartridge body 1 along the axial direction of the cartridge body 1. As shown in the figure, the chamber 10 has an outlet end 11 formed at the bottom of the cartridge body 1, and the chamber 10 also has an inlet end 12 formed at the top of the cartridge body 1. The cartridge body 1 can also have other shapes, and the chambers 10 can be arranged around the axis of the cartridge body 1 or according to other rules.

[0034] As shown in Figure 1 and Figure 2As shown, the reagent bin 100 further comprises a fixed plate 2 and a sealing gasket 3. The fixed plate 2 and the sealing gasket 3 can be locked by screws, and the sealing gasket can be a rubber gasket. The fixed plate 2 is connected to the bin body 1 and located at the side of the bin body 1 having the outlet end 11. The fixed plate 2 has a plurality of first through holes 20, which are arranged one by one in correspondence with the number of the chambers 10. The sealing gasket 3 is clamped between the fixed plate 2 and the bin body 1, and the sealing gasket 3 is provided with a plurality of second through holes 30, which are arranged one by one in correspondence with the number of the chambers 10. The second through holes 30 are arranged so that the injection needle does not need to be punctured to form a cavity, but is directly inserted into the chamber 10 through the second through hole 30, preventing the sealing gasket 3 from being expanded to affect the use effect due to the injection needle inserted to form a hole.

[0035] In addition, as shown in Figure 1 and Figure 2 , the second through hole 30 is used for being inserted by the injection needle, and the injection needle is in interference fit with the sealing gasket 3.

[0036] The bin body 1 is provided with a plurality of chambers 10, and a plurality of reagents can be directly injected into the chambers 10. The sealing gasket 3 and the fixed plate 2 are arranged at the bottom of the bin body 1. When the injection needle is inserted into the chamber 10 through the first through hole 20 and the second through hole 30, the sealing gasket 3 cooperates with the injection needle to allow the reagent to flow out of the injection needle and not to leak from other places. The reagent bin 100 can accommodate a plurality of reagents at one time, and is directly installed on the urine test instrument to achieve one-time installation of a plurality of reagents. When replacing, it is not necessary to replace each bottle one by one, but only to disassemble the whole, which is simple and convenient to operate, reduces the operation frequency, prevents the reagents from being placed in the wrong place, reduces the error rate, reduces the assembly difficulty, and improves the efficiency.

[0037] In addition, as shown in Figure 1 and Figure 2 , a sealing film 5 is clamped between the fixed plate 2 and the sealing gasket 3. Before the reagent bin 100 is used, the sealing film 5 is not punctured to cover the outlet end 11. After the reagent bin 100 is installed on the urine test instrument, the injection needle of the urine test instrument punctures the sealing film 5 to enter the chamber 10 from the second through hole 30. The sealing film can be a plastic film or a thin film, which covers the second through hole to prevent liquid from flowing out, and the injection needle can be punctured for use at a later stage.

[0038] In addition, as shown in Figure 1 and Figure 2 , a groove is arranged around the bottom of the bin body 1, and the sealing gasket 3 is at least partially embedded in the groove.

[0039] Further, as shown in Figure 1 and Figure 2As shown, each first through hole 20 and each second through hole 30 is coaxially arranged with the corresponding outlet end 11. In some embodiments, the bottom of the cartridge body 1 is provided with a mounting channel, and the chamber 10 is arranged around the outer periphery of the mounting channel. Other components on the urine test instrument are inserted into the mounting channel to achieve installation of the reagent cartridge 100.

[0040] Further, as shown in Figure 1 and Figure 2 , the reagent cartridge 100 further comprises a leak-proof member 4 arranged in the chamber 10, for preventing fluid from leaking out of the inlet end 12.

[0041] Further, as shown in Figure 1 and Figure 2 , the leak-proof member 4 has a through hole 40, and the leak-proof member 4 is slidably arranged along the cavity wall of the chamber 10, and the through hole 40 extends along the extension direction of the chamber 10.

[0042] In addition, as shown in Figure 1 and Figure 2 , the fluid includes a reagent and a liquid seal oil, the chamber 10 is used to inject the reagent and the liquid seal oil, and the liquid seal oil is closer to the inlet end 12 than the reagent. The leak-proof member 4 is inserted into the liquid seal oil, the aperture range of the through hole 40 of the leak-proof member 4 is 0.1mm-10mm, optionally, the aperture range of the through hole 40 of the leak-proof member 4 is 0.1mm-5mm, or 4mm-5mm. In addition, the aperture of the through hole 40 of the leak-proof member 4 is 4.5mm, 4.7mm or 4.8mm. In use, the reagent is injected into the chamber 10 from the inlet end 12, and then the liquid seal oil is injected, and at the same time, the leak-proof member 4 is inserted into the liquid seal oil. In this way, the diameter of the chamber 10 is reduced in the region close to the inlet end 12 while ensuring the storage space in the chamber 10, so that the fluid in the chamber 10 will not shake and leak out of the inlet end 12 when the reagent cartridge 100 is sent, used or overturned. At the same time, the use amount of the seal oil can be reduced, the size of the leak-proof member can be adjusted according to the size of the reagent cartridge, and the leak-proof member can be adapted to various reagent cartridges, or the same leak-proof member can be adapted to reagent cartridges of different sizes, and the leak-proof member is an oleophilic material.

[0043] Further, the outer diameter of the leak-proof member 4 is smaller than the inner diameter of the chamber 10 by 0.1mm-4mm, optionally, the outer diameter of the leak-proof member 4 is smaller than the inner diameter of the chamber 10 by 0.5mm-2mm, and the leak-proof member 4 can descend with the liquid level after the reagent is used.

[0044] A plurality of chambers 10 are arranged around the central axis of the cartridge body 1, and the distances from some of the chambers 10 to the central axis of the cartridge body 1 are different. Specifically, as shown in Figure 3In the embodiment, the center axis of the cartridge body 1 is surrounded by two rings of cavities 10, and the cavities 10 located in the outer ring are located between the two cavities 10 in the inner ring in the radial direction, so that more cavities 10 can be arranged, more reagents can be placed, and the distance from the cavities in the same ring to the center axis of the cartridge body can be equal. In other embodiments, the cavities can be arranged in more forms, and one ring or more than two rings can be arranged.

[0045] In addition, as shown in Figure 3 the top of the cartridge body 1 is provided with a recessed area, and the reagent cartridge 100 further comprises a pulling member 6 arranged in the recessed area. The recessed area can also be arranged on the side wall of the cartridge body 1. In the embodiment, the pulling member 6 can be a bracelet, which is hingedly connected to the cartridge body. When in use, the bracelet can be pulled out of the recessed area, facilitating the installation and removal of the reagent cartridge.

[0046] Further, as shown in Figure 3 the side of the cartridge body 1 is further provided with a limiting member 7, which can be a protruding member. When the reagent cartridge is in use, the limiting member 7 matches the corresponding mounting position, so that the reagent cartridge can be accurately installed, and the cavity position can be aligned with the injection needle.

[0047] Another embodiment of the utility model relates to a urine test instrument, which comprises the reagent cartridge 100 of the above embodiment, and the reagent cartridge 100 is an integral replaceable component.

[0048] The urine test instrument can be used on a toilet or independently, and can be used to obtain a urine sample and mix reagents with the urine sample. The urine test instrument can be used for routine urine tests, such as 14 ascorbic acid tests, including vitamin (C, VC), white blood cells (WBC), urobilin (URO), bilirubin (BIL), occult blood (BLD), nitrite (NIT), pH, protein (PRO), specific gravity (SG), urine ketone (KET), urine glucose (GLU), urine creatinine (CR), urine calcium (CA), and trace albumin (MA) + UACR (urine trace albumin / creatinine ratio) + UPCR (urine protein / creatinine ratio) + urine uric acid comprehensive value (based on CKD-EPI algorithm).

[0049] Understandably, the reagent cartridge 100 can be used in other instruments, such as blood testing instruments, in addition to being used in the urine test instrument in the embodiment.
