Problems solved by technology

[0004] Among them, the disadvantage of the first method is that it is troublesome for the patient to carry and transport the sample, and the storage time of the sample is limited. If the storage time is too long, the hemoglobin will be degraded, resulting in missed detection.
The disadvantage of the second method is that the sample is exposed during the operation of the doctor, which is easy to cause environmental pollution, and may also cause infection to the operator. At the same time, there is also a cumbersome operation process.
The third method, although there is no obvious cumbersome operation, requires a special laboratory for detection operation, which makes the detection time too long and inconvenient

Embodiment 1

[0079]Embodiment 1: As shown in the figure, this sample collection and detection device includes a collection card 100 and a detection card 1. The detection card 1 is made of plastic and includes an upper plate 4 and a lower plate 2 connected together; the upper plate 4 The bottom is provided with a positioning column 12, and the lower plate 2 is provided with a positioning hole 13 matching the positioning column 12, and the upper plate 4 and the lower plate 2 are connected together through the cooperation of the positioning column 12 and the positioning hole 13. Such a connection is stable and easy to assemble. Described lower plate 2 and through hole 4-1 corresponding position are provided with raised positioning bridge 18, and this positioning bridge 18 has arched bridge deck 11, and bridge deck 11 both sides are provided with bridge railing 19; The width of bridge deck 11 Matches the width of test strip 3. The lower plate 2 is provided with a test strip 3, and the test st...

Embodiment 2

[0088] Embodiment 2: as Figure 16 and Figure 17 As shown, the difference from Embodiment 1 is that the upper surface of the upper plate 4 is composed of two stepped upper and lower planes, and the connection between the two planes is formed to limit the insertion depth of the collection card 100. The upper plane of the retaining wall 10 extends horizontally to form a positioning lock 6 , and a liquid filling hole 7 is opened on the positioning lock 6 corresponding to the through hole 4 - 1 on the lower plane 6 . In this way, the positioning lock 6 is suspended above the through hole 4 - 1 , and there is a gap between the positioning lock 6 and the surface of the upper plate 4 where the collection card 100 is inserted.

Embodiment 3

[0089] Embodiment 3: as Figure 18 and Figure 19 As shown, the difference from Embodiment 2 is that: the two sides of the upper surface of the upper plate 4 are provided with side retaining walls 20 that cooperate with the collection card 100, and the lower plate 2 is provided with a drainage strip corresponding to the through hole 4-1. 21. The drainage strip 21 corresponds to the through hole 4-1 and the sample receiving area 3-4 respectively.

Abstract

The invention relates to a sample testing apparatus and a testing method. The sample testing apparatus comprises a testing card and a collecting card, wherein the testing card comprises an upper plate and a lower plate which are connected together; a testing strip is arranged between the upper plate and the lower plate; the upper plate is provided with a reading window and provided with a throughhole corresponding to the testing strip; the collecting card comprises an upper card and a lower card; a film carrier for carrying samples is arranged between the upper card and the lower card; and the testing card and the collecting card are provided with a socket device and a plug-in device which are mutually matched respectively. The testing method comprises the following steps: collecting samples to the film carrier of the collecting card; inserting the collecting card into the testing card; dripping a testing liquid and making the liquid flow to the testing strip through the film carrierin the collecting card; and reading testing results and so on.

Description

[0001] This application is a divisional application of patent application 200410067068.8. technical field [0002] The invention relates to a medical article, in particular to a sample detection device and a detection method for detecting fecal occult blood. Background technique [0003] Fecal occult blood detection is one of the important means to prevent intestinal diseases. Currently, the immunological method used to detect fecal occult blood adopts the double-antibody sandwich method. This method includes the following steps: the patient collects stool samples by himself and gives them to the doctor. samples for rapid immunoassay. Specifically, there are mainly the following methods. The first is that the patient collects the stool sample in a plastic container containing an aqueous solution at home, and then gives it to the doctor. The doctor adds the aqueous solution containing the sample to be tested dropwise on the test device equipped with a reagent strip, and then...
