Background

In recent years, domestic infectious diseases and epidemic situations have been increasing year by year. For the detection of infectious diseases and epidemic situations, the molecular detection is a gold standard, and the sensitivity and the accuracy of the molecular detection are higher than those of an immunodetection method. However, the current nucleic acid detection needs to be supported by a central laboratory and professional instruments and personnel, so that the detection period is long, and even treatment is delayed or infection spread is caused. If a patient suspected of having influenza is detected, at least 1-2 days are required from the arrival at a sampling site, the sample is sent to a central laboratory, and the detection is carried out until the result is obtained, and the disease can rapidly progress or the infection spreads in the period of time; the African swine fever epidemic situation which is seriously popular in the year needs 5-7 days from sample sending to result obtaining of basic-level farms and slaughtering enterprises, detection results are not always waited for, pigs are already sick and dead, and the swine plague can be spread on a large scale without isolation in the period, so that the swine plague situation has more extensive influence. The on-site rapid detection method based on nucleic acid molecule diagnosis can greatly improve the speed and accuracy of on-site detection, which has great significance for epidemic control, prevention and treatment.

However, the detection method based on nucleic acid molecule requires sample pretreatment, and the conventional sample pretreatment method still has the problems of needing professional auxiliary equipment, complex extraction process, easy occurrence of cross contamination and the like, and on the other hand, the on-site rapid detection method based on nucleic acid molecule diagnosis provides higher requirements for the sample pretreatment method.

Referring to fig. 1 to 3, a detection kit 100 according to a preferred embodiment of the present invention includes a first reagent storage sleeve 1, a second reagent storage sleeve 2 connected to the first reagent storage sleeve 1, and a cover 3 screwed to the second reagent storage sleeve 2. The first reagent accommodating sleeve 1 includes a first accommodating groove 11 for accommodating a first reagent and a second accommodating groove 12 surrounding the first accommodating groove 11 for accommodating a second reagent, wherein the first accommodating groove 11 and the second accommodating groove 12 are not communicated, and in this embodiment, the first reagent is a mixture of two reagents. Indeed, in other embodiments, the first reactant may be a separate reagent, which is not specifically limited herein, as the case may be. It is noted that the notches 13 of the first and second receiving

grooves

11 and 12 are disposed toward the cover 3, and the cover 3 is disposed upward when the assay cartridge 100 is placed upright.

In the above, since the first reactant is a mixture of two kinds of reagents, in order to enhance the two kinds of actual activities, the first housing groove 11 has the pointed portion 15, and the pointed portion 15 is provided to protrude from one end of the second housing groove 12. The tip portion 15 is provided for the purpose of: the tip 15 tends to concentrate the heat as the first reactant is heated. The first reactant may be contained within the tip portion 15 and the tip portion 15 may then be heated to increase the activity of the first reactant. In order to facilitate the forward placement of the detection kit 100 when the detection kit 100 is not in use so as to prevent the first and second reagents from flowing out of the first and second receiving

grooves

11 and 12 and then reacting, the detection kit 100 further comprises a base 4 which is sleeved on at least a portion of the outside of the first reagent receiving sleeve 1 and is detachably connected to the second reagent receiving sleeve 2.
