Description

Technical Field

[0001] The utility model relates to the field of reagent test cards, in particular to a rapid total colony count test card. Background Art

[0002] The rapid total colony count test card is a portable test tool developed based on modern biotechnology and rapid detection principles; it adopts a unique color reaction mechanism and can rapidly perform qualitative and semi-quantitative detection of the total colony count in samples such as food, water quality, and environment in a short time; the test card has the characteristics of simple operation, intuitive results, and fast detection speed, and is suitable for on-site rapid screening and preliminary evaluation;

[0003] However, there are also some technical defects in the existing rapid total colony count test cards; among them, the most significant problem is that it can only perform a single detection on a single sample; this means that each detection can only analyze one sample and cannot process multiple samples simultaneously; this to a certain extent limits the application range and detection efficiency of the test card, especially in occasions where a large number of screening samples are required, and its limitations are more obvious;

[0004] In addition, the existing rapid total colony count test cards cannot perform multiple detections on a single sample. Once the detection of a sample is completed, if re-detection is required, the sample needs to be re-collected and processed, which undoubtedly increases the cost and time of detection; for samples that require continuous monitoring or multiple confirmations, this limitation is obviously disadvantageous. Summary of the Utility Model

[0005] In order to solve the problem that the existing rapid total colony count test cards can only perform a single detection on a single sample, the utility model provides a rapid total colony count test card;

[0006] The rapid total colony count test card provided by the utility model adopts the following technical solutions:

[0007] A rapid total colony count test card includes a housing, a fixing part, and a cover plate. The cover plate is movably connected to the inside of the housing through the fixing part; a turntable is rotatably connected to the bottom inside the housing; a plurality of slots for detecting samples are formed on the top of the turntable, and sample test cards are arranged in the slots for detecting samples; corresponding identification blocks are arranged on the top of the turntable on one side of each sample test card; indicating holes and detection holes corresponding to the sample test cards and the identification blocks are formed inside the cover plate.

[0008] Further, the number of both the sample test cards and the identification blocks is N, N≥2; the sample test cards and the identification blocks are distributed in a circular shaft array on the top of the turntable;

[0009] Furthermore, a retaining ring is integrally formed at the top of the turntable corresponding to each sample test card. The retaining ring is arranged outside the sample test card to prevent the sample from flowing out of the sample test card.

[0010] Furthermore, a gear ring is sleeved on the outer side wall of the turntable; an adjustment hole is formed in the outer side wall of the housing; a regulating wheel is rotatably connected to the bottom inside the housing; one side of the regulating wheel extends to the outside of the housing through the adjustment hole; a tooth groove meshing with the gear ring is formed in the outer side wall of the regulating wheel.

[0011] Furthermore, a limiting ring is integrally formed at the bottom inside the housing; the turntable is arranged inside the limiting ring; a break groove for avoiding the regulating wheel is formed inside the limiting ring.

[0012] Furthermore, a sealing film for sealing the sample test card is respectively pasted on the top of each retaining ring.

[0013] Furthermore, an outer packaging film for sealing the indicating hole and the detection hole is pasted on the top of the cover plate.

[0014] In summary, the beneficial effects of the present utility model are as follows:

[0015] By adding a turntable rotatably connected inside the housing, as well as identification blocks, sample test cards, indicating holes, and detection holes, the present utility model can achieve the purpose of simultaneously detecting the total number of alkaline colonies of multiple samples and detecting the total number of colonies of a single sample multiple times. Through the above design, compared with the prior art in which one test card can only be used for detecting one sample, the present utility model can use one test card for detecting multiple or multiple samples. The user can drop different samples into different sample test cards and record the corresponding identification blocks for each sample test card for detecting the total number of colonies of different samples, increasing the application range and detection efficiency of the test card.

[0016] At the same time, the same sample can also be dropped into different sample test cards for multiple detections, and the data can be summarized and compared to improve the detection accuracy of the data and avoid errors. BRIEF DESCRIPTION OF THE DRAWINGS
