Description

Fool-proof assembly structure of sampler and kit Technical Field The utility model relates to the technical field of biochemical immunoassay, in particular to a foolproof assembly structure of a sampler and a kit. Background The full-automatic biochemical immunity analyzer is one device for completing biochemical immunity related item inspection at the same time. The automatic detection is realized by installing the kit on the fixed seat and then moving the fixed seat to different stations of the full-automatic biochemical immunity analyzer. In order to be matched with the full-automatic biochemical immunity analyzer, a sample cavity, a detection cavity and the like are arranged on the kit. The Chinese patent publication No. CN209535773U discloses a detection kit, which comprises a kit main body and a reagent card cover, wherein the kit main body is provided with a test paper storage part, a detection cavity, a reagent containing part for containing reagents and a sample cavity, the reagent card cover is matched with the kit main body, the reagent card cover is provided with a card cover containing position matched with the reagent containing part, a card cover detection position matched with the detection cavity, a sampling position and a sample suction position, the sampling position is provided with a sampling head assembly, the sample suction position is provided with a sample suction part, and the sampling head assembly comprises a sampling head main body, a cone opening arranged on the sampling head main body, a sampler communicated with the cone opening and a handle arranged on the sampling head main body. The whole sampling head assembly of the detection kit in the prior art is square, the direction identification degree is low, and the direction misjudgment is easy to generate when a user assembles the assembly. When the sampling head assembly is assembled on the sampling placement position in an incorrect direction, the problems of 1, the stability of assembly are easily caused by the fact that the sampling head assembly is not firmly assembled with the reagent kit main body, the sampling head assembly is easily separated from the reagent kit main body, 2, the detection flow is interrupted, if a blood sample is stored in the sampling head assembly, the follow-up detection cannot be normally carried out due to the separation, and 3, the biosafety risk is that the blood sample can leak and pollute the inside of a detection instrument, and if the blood sample carries pathogens, cross contamination or user exposure risk can be further caused. Accordingly, the prior art is still in need of improvement and development.
