Problems solved by technology

However, the detection process involves transferring the sample from the sample processing device to the detection device, which requires multiple steps to complicate the detection process
In addition, the sample is generally transferred by means of a pipette or a plastic straight straw. During the transfer of the sample, the sample may accidentally drip or the excess sample may overflow from the sample hole due to uncontrolled sample dripping, thereby Lead to biological contamination of the environment; it may also cause inaccurate test results due to inaccurate transfer of sample volume due to i

Embodiment 1

[0065] Figure 1.1 and Figure 1.2 A device of the invention is described. The sample collection and detection auxiliary device includes a test paper card holder and a reagent carrying device 4 .

[0066] The assembled test paper card holder is composed of a lower bottom 1, an upper cover 2, a detection test paper 3 and a card holder 5. There is a storage slot for fixing the detection test paper on the lower bottom 1, and the detection test paper 3 is fixed in the detection test paper storage tank of the lower bottom 1 according to the upper alignment method, and the detection test paper is clamped and fixed by the positioning rib to avoid its internal and external sliding. When fastening the upper cover 2 and the lower bottom 1, the interference fit is carried out through the positioning fastener 1.1 at the end of the lower bottom and the positioning fastener 2.1 at the end of the upper cover to ensure that the upper cover 2 and the lower bottom 1 are completely sealed; 5 F...

Embodiment 2

[0072] Figure 2.1 and Figure 2.2 A device of the invention is described. The sample collection and detection auxiliary device includes a test paper card holder and a reagent carrying device 4 .

[0073] The assembled test paper card set is composed of a lower bottom 1, an upper cover 2, and a detection test paper 3. There is an accommodating slot for fixing the test paper on the lower bottom 1. Fix the test paper 3 in the test paper accommodating slot of the lower bottom 1 according to the upper alignment method and clamp it tightly. When the upper cover 2 is fastened with the lower bottom 1, the The end positioning fastener 1.1 and the upper cover end positioning fastener 2.1 perform interference fit to ensure that the upper cover 2 and the lower bottom 1 are completely sealed;

[0074] The reagent carrying device 4 can be pre-packed with a certain amount of liquid, and it can be heat-sealed with a parafilm or sealed with a cover to ensure that the device has no liquid l...

Embodiment 3

[0079] Figure 3.1 and Figure 3.2 A device of the invention is described. The sample collection and detection auxiliary device includes a test paper card holder and a reagent carrying device 4 .

[0080] The assembled test paper card holder is composed of a lower bottom 1, an upper cover 2 and a detection test paper 3. There is a storage slot for fixing the detection test paper on the lower bottom 1, and the detection test paper 3 is fixed in the detection test paper storage slot of the lower bottom 1 according to the upper alignment; when the upper cover 2 and the lower bottom 1 are fastened, pass The end positioning fastener 1.1 and the upper cover end positioning fastener 2.1 perform interference fit, and at the same time, the lower bottom tail positioning fastener 1.1 and the upper cover tail positioning fastener 2.1 also perform interference fit, based on the transition between the top and tail of the cover body Fit tightly to ensure that the upper cover 2 and the lower...

Abstract

The invention discloses a detection auxiliary device, which is used for assisting detection test paper to bear a sample and displaying a detection result, and comprises a reagent bearing device and a test paper clamping sleeve mutually inserted. When the test paper clamping sleeve is clamped with the reagent bearing device, the sample suction section of the test paper is immersed into a sample solution of the reagent bearing device to finish sample bearing work.

Description

Technical field: [0001] The invention belongs to the technical field of rapid diagnosis and detection, and in particular relates to a detection auxiliary device. Background technique: [0002] In current medical diagnostic products, the detection of various sample types to be tested (nasopharyngeal secretions, saliva, urine, blood, sweat, etc.) usually requires pre-processing of samples, usually through a separate The sample processing device is used to pre-process the sample to be tested (dilute or elute the sample) to obtain a sample that is more suitable for detection. Manually transfer the sample from the sample processing device to the sampling hole equipped with the test strip detection device, wait for the reaction time to end, and then observe with the naked eye or read the test result with the aid of an instrument. Judging whether the sample contains the target to be detected according to the test results, the above method is now a relatively mature and common meth...
