Problems solved by technology

It is easy to leak when the sample is mixed and the lid is opened, and there is an odor during the whole process of dropping the sample and interpreting the results, etc., which will affect the testing personnel.
Since sampling is usually done by non-professionals, the amount of sampling is often too much, which affects the test results

Embodiment 1

[0044] Embodiment 1: shell structure

[0045] Such as figure 1 The upper cover of the middle shell 1 and figure 2 The middle and outer casings 6 together form the complete casing of the kit, that is, the outer packaging.

[0046] Such as figure 1 Inner shell inner concave ring 2 figure 2 The middle and inner concave ring 5 are large and small and adapt to form a closed cover.

[0047] Such as figure 2 The inner cavity body 3 is the main shell of the reagent box, and the figure 2 round hole 4 and figure 2 The inner cavity body 7 fixes the sampling rod.

Embodiment 2

[0048] Example 2: Sampling stick

[0049] Such as image 3 The middle 10 is an undercut, and there are 12 undercuts at the upper end of the sampling rod. Such as image 3 Middle 11 is the cylinder at the front end of the sampling rod, such as image 3 Middle 8 is the thread at the front end of the sampling rod: in order to ensure sufficient sample volume, lengthen the thread length and deepen the thread groove. image 3 Middle seal groove 9 with Figure 5 The sealing ring 29 is suitable in size.

Embodiment 3

[0050] Embodiment 3: detection reagent bottle main body

[0051] Such as Figure 6 Top bezel 13 with Figure 6 The bottom ring opening 19 is all plastic-sealed with aluminum foil. When using the kit, tear off the top 13 aluminum foil plastic seal.

[0052] Such as Figure 6 top groove 14 with image 3 Combined with the undercut 10, the sampling rod is locked after sampling to prevent unnecessary repeated sampling.

[0053] Such as Figure 6 Seal ring groove 15 with Figure 9 The sealing ring 28 is suitable in size.

[0054] Such as Figure 6 Desiccant storage tank 17: After the desiccant is placed, the sealed space where the test strip is located can be kept dry;

[0055] Such as Figure 6 Inclined baffle 18 of the tube body: guides the main body of the detection reagent bottle to be conveniently loaded into the main shell of the kit.

[0056] Such as Figure 7 Test strip draw-in slot seat 23: install and detect the test strip, the length and width of the test stri...

Abstract

The invention provides an integrated device and method for rapidly detecting fecal transferring. The integrated device is characterized by comprising a sampling rod, a detection reagent bottle body, areagent bottle body shell and a pricking pin. The integrated device is simple and convenient in sample detection, and does not need a complex sample treatment process; the detection process is carried out in a closed environment, so that there is no peculiar smell, and the detection process is friendly to non-professionals (such as family users or non-clinical laboratory doctors); and the workload of professionals can be reduced, and a large number of samples can be rapidly processed. By designing the integrated device, the excrement sampling amount is constant, and the consistency of detection results is improved; sample feeding is integrated with sample detection, so that operation is simplified; detection and result interpretation are both completed in the closed isolated space, peculiar smells are isolated, and the method and device are friendly to operators.

Description

technical field [0001] The invention relates to a detection device, in particular to a rapid detection device and a detection method for a biological sample. Background technique [0002] Routine fecal occult blood test can detect a small amount of gastrointestinal bleeding, which is helpful to clarify the cause of gastrointestinal bleeding. When gastrointestinal bleeding, especially a small amount of bleeding from upper gastrointestinal lesions, the hemoglobin in the blood is reacted by gastric acid, digestive enzymes and bacteria, resulting in a decrease in the antigenicity of hemoglobin, which has a negative impact on the detection of hemoglobin by the double-antibody sandwich method, and is prone to "false." Negative”, leading to missed diagnosis. During gastrointestinal bleeding, transferrin in the blood will also enter the gastrointestinal tract. Because of its strong antibacterial ability in the intestinal tract and its stability is higher than that of hemoglobin, th...
