The kit in the embodiment has the advantages of simple installation method, easy operation, convenience for production of the kit, and simple and reliable structure of the installed kit.

The present application also provides a kit assembled by the method of any of the embodiments. For a specific installation method, please refer to the description of the fourth embodiment, which is not repeated herein. In this embodiment, the microporous sheet 20 in the installed reagent kit is located at one side of the via hole 12 close to the front pool 11, so that when the reagent kit performs sample detection, the microporous sheet 20 can be tightly attached to the kit body 10 under the action of the pressure of the sample, thereby improving the accuracy of the sample detection.

Front cell electrode 113 is fixed to fixing plate 112 of front cell 11 away from rear cell 13, and rear cell electrode 132 is fixed to side plate 131, and side plate 131 is connected to side wall 114 of front cell 11. The front cell electrode 113 and the rear cell electrode 132 are fixed in a simple manner and are convenient to assemble. In addition, the front cell electrode 113 and the rear cell electrode 132 may be electrode plates, which are respectively fixed to the fixing plate 112 and the side plate 131 by being inserted and fixed with glue, so that the front cell electrode 113 and the rear cell electrode 132 are not easily loosened, thereby improving the reliability of the reagent kit.

Further, the cross-sectional area of the rear cell 13 is gradually reduced toward the pressure-applying cell 15 to increase the speed of sample detection.

For other structures of the kit, please refer to the descriptions of the first to third embodiments, which are not repeated herein.

The embodiment of the present application further provides a point-of-care testing (POCT) blood cell analyzer, which includes the kit of any one of the foregoing embodiments and a detection seat matched with the kit, and the POCT blood cell analyzer is used for analyzing a blood sample. For the specific structure of the kit, please refer to the drawings of the foregoing embodiments and the related text descriptions, which are not repeated herein.

The above description is only an embodiment of the present application, and is not intended to limit the scope of the present application, and all equivalent structures or equivalent processes performed by the present application and the contents of the attached drawings, which are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
