Sliding type sample adding integrated colloidal gold card box

Abstract

The invention relates to a sliding type sample adding integrated colloidal gold card box comprising a shell; the shell comprises an upper shell body and a lower shell body which are connected with each other, and an overturning handle rotationally arranged between the upper shell body and the lower shell body; a blood sampling capillary tube is arranged in the middle of the overturning handle; reagent paper for detection is arranged in the shell; a blood feeding opening and an observation opening are formed in the upper shell, and the blood sampling capillary tube can be located in the blood feeding opening by the overturning handle; a buffering agent placing box is arranged on the lower shell in the shell, and a buffering agent packaged by a plastic film is arranged in the buffering agent placing box; a sliding rail block is arranged on the side, located on the buffering agent placing box, of the lower shell, a sliding block is arranged in the sliding rail block in a sliding mode, the sliding block comprises a sliding block body arranged in the sliding rail block in a sliding mode, a sliding block head located outside the lower shell is arranged at the end of the sliding block body, sharp thorns are further arranged at the end of the sliding block body, and a buffering agent can be punctured through thorns after the sliding block body moves. The device can achieve the functions of blood sampling, buffer agent adding and detection at the same time.

Description

technical field [0001] The invention relates to a detection box, in particular to a sliding type sample-adding integrated colloidal gold card box. Background technique [0002] Colloidal gold method is that chloroauric acid (HAuCl4) can be polymerized into gold particles of a certain size under the action of reducing agents such as white phosphorus, ascorbic acid, sodium citrate, tannic acid, etc., and become a stable colloidal state due to electrostatic interaction. , forming a negatively charged hydrophobic colloidal solution, which becomes a stable colloidal state due to electrostatic interaction, so it is called colloidal gold. Colloidal gold is also an ideal immune marker in immunoelectron microscopy. [0003] Colloidal gold immunochromatography is a commonly used immunocolloidal gold detection technique. Specific antigens or antibodies are immobilized on the membrane in the form of strips, and colloidal gold labeling reagents (antibodies or monoclonal antibodies) are ...

AI Technical Summary

Problems solved by technology

[0004] The detection box in the prior art generally drips the blood onto the diagnostic test strip after blood collection by a blood collection device, and at the same time adds a certain buffer to react to realize the detection. The agent and the detection box are separated, and three different instruments need to be operated during use, and the efficiency is also low
