Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The following description is made in detail for the application of the principles of the present invention with reference to the accompanying drawings.
The kit comprises a separation column 1 and a detection column 2 which are connected with each other, and is connected together through a thread structure 4 which is arranged on the outer wall of the separation column 1 and the inner wall of the detection column 2 and matched with each other. The inner cavity of the separation column 1 is filled with a chromatographic column 101 for separation, and a quantitative reagent for detection is placed in the detection column 2. The collected sample is added into the liquid to be detected obtained after being separated by the chromatographic column 101 from the upper end of the separation column 1, and the liquid to be detected flows into the detection column 2 from the lower end of the separation column 1 for detection, and the chromatographic column 101 is selected according to the components of the separated liquid.
The detection column 2 comprises a liquid receiving cavity 201 at the upper end and a detection cavity 202 at the lower end, a detection reagent for detection is placed in the detection cavity 202, and an openable sealing mechanism is arranged at the joint of the detection reagent and the detection cavity 202.
The bottom end of the separation column 1 is a funnel structure 100, the funnel structure 100 is inserted into the liquid receiving cavity 201, and the distance from the bottom end of the funnel structure 100 to the sealing mechanism is constant. When the liquid level of the separated detection liquid received from the liquid receiving cavity 201 contacts with the bottom end of the funnel, the internal and external air pressures are balanced, and the detection liquid at the upper end stops flowing downwards. The sealing mechanism is then opened to allow the separated liquid to be analyzed and detected to flow into the detection chamber 202 to react with the detection reagent.
The sealing mechanism comprises a first isolation sheet 301 and a second isolation sheet 302 which are tightly attached to each other, the first isolation sheet 301 rotates relative to the second isolation sheet 302, a window 305 is arranged at the position, deviating from the center of a circle, of the first isolation sheet 301 and the second isolation sheet 302, and the first isolation sheet 301 and the second isolation sheet 302 rotate to realize the superposition or closing of the two windows 305.
The diameter of the window 305 is smaller than or equal to the diameter of the first spacer 301 or the second spacer 302, and is located in a semicircular region.
During the rotation, the detection chamber 202 performs a parallel rotation with a constant height with respect to the liquid receiving chamber 201. Specifically, the positions of the contact walls of the detection cavity 202 and the liquid receiving cavity 201 comprise a groove and a flange 303 which are mutually clamped.
And the limiting mechanism is connected with the sealing mechanism and comprises a through hole arranged at a position corresponding to the groove or the flange 303 and a shaft pin 304 inserted into the through hole. After a certain amount of detection liquid is obtained in the liquid receiving cavity 201, the user pulls out the shaft pin 304, so that the detection cavity 202 can be rotated, the windows 305 on the first spacing sheet 301 and the second spacing sheet 302 are overlapped, and after the detection liquid rapidly flows into the detection cavity 202, the detection cavity 202 is rapidly rotated, so that the windows 305 on the first spacing sheet 301 and the second spacing sheet 302 are staggered with each other, and the upper end of the detection cavity is prevented from flowing in with new detection liquid. Meanwhile, the test can be performed by adding a certain amount of detection liquid into the detection cavity 202 for multiple times by controlling the opening of the sealing mechanism.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
