Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and specifically relates to a sample storage device for a quantum dot fluorescence immunoassay analyzer. Background Art

[0002] Quantum dot fluorescence immunoassay analyzer is usually composed of one or more of the following: sample addition module, reaction module, optical detection module (fluorescence), data processing module, incubation temperature control module, cleaning and separation module, etc. The principle is generally to convert the fluorescence signal into a digital signal, and the concentration value is calculated by the data processing system.

[0003] The sample tubes used in quantum dot fluorescence immunoassay analyzers are usually specially designed to collect and store samples to be tested to ensure the integrity and stability of the samples, such as human whole blood, serum, plasma, peripheral blood, urine, and feces.

[0004] Current sample tubes cannot be stably fixed on the sample tube rack when in use, because the inner diameter of the placement hole on the sample tube rack is usually larger than the outer diameter of the sample tube, resulting in an inevitable gap between the sample tube and the placement hole after the sample tube is placed. This gap makes it impossible for the sample tube to be firmly fixed on the sample tube rack, and thus it is easy to shake during movement or detection, which can easily affect the progress of the detection. Utility Model Content

[0005] The purpose of the utility model is to provide a sample storage device for a quantum dot fluorescence immunoassay analyzer, which can cleverly fill the gap between the straight tube and the placement hole by utilizing the unique structure of the conical air bag, significantly enhance the fixing stability of the straight tube in the placement hole, effectively avoid the shaking of the straight tube during movement or detection, and ensure the smooth progress of the experimental process.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A sample storage device for a quantum dot fluorescent immunoassay analyzer comprises a straight tube, the bottom inner wall of the straight tube is provided with a conical bottom, the outer wall of the straight tube is provided with a conical airbag, the interior of the conical airbag is filled with an inert gas, a cap is screwed on the top thread of the straight tube, and a sealing component is provided at the bottom of the cap.

[0008] Furthermore, the conical airbag is provided with a wear-resistant layer, a buffer layer and an airtight layer in sequence from the inside to the outside, the wear-resistant layer is fixedly connected to the buffer layer, and the buffer layer is fixedly connected to the airtight layer.

[0009] Furthermore, the outer wall of the conical airbag is provided with anti-slip grooves.

[0010] Furthermore, a top ring is fixed to the bottom of the cap, a hollow rubber elastic ring is arranged on the inner side of the top ring, and a fixing ring is arranged on the outer wall of the straight tube and below the hollow rubber elastic ring.

[0011] Furthermore, a rotating ring is rotatably mounted on the outer wall of the straight tube and located below the fixed ring, and a connecting belt connected to the cover cap is fixed on the outer wall of the rotating ring.

[0012] Furthermore, a sealing ring is fixed on the inner top wall of the cap and is in sealing contact with the top of the straight tube.

[0013] The technical effects achieved by this utility model are:

[0014] The present invention is a practical sample storage device for a quantum dot fluorescent immunoassay instrument. The conical air bag is provided. When a straight tube is placed in a placement hole of a sample tube rack, the unique structure of the conical air bag can cleverly fill the gap between the straight tube and the placement hole, significantly enhancing the fixing stability of the straight tube in the placement hole, effectively avoiding the shaking of the straight tube during movement or detection, and ensuring the smooth progress of the experiment process; the anti-slip grooves provided increase the friction of the outer wall of the conical air bag, thereby improving the stability of holding by hand and the stability of placing in the placement hole, which is relatively practical; the sealing component provided drives the top ring to move downward when the cover cap is rotated, cooperates with the fixing ring, squeezes the hollow rubber elastic ring, causes the hollow rubber elastic ring to expand to both sides, and makes the hollow rubber elastic ring tightly attached to the inner side of the top ring and the outer wall of the straight tube, thereby improving the sealing performance of the cover cap connection.

[0023] like Figure 1 , 2 As shown in Figure 4, a top ring 6 is fixed to the bottom of the cap 5, a hollow rubber elastic ring 8 is arranged on the inner side of the top ring 6, and a fixing ring 7 is arranged on the outer wall of the straight tube 1 and below the hollow rubber elastic ring 8. The structure is simple and the operation is convenient. The sealing performance of the connection between the cap 5 and the straight tube 1 is increased. When the cap 5 is screwed to the top of the straight tube 1, the cap 5 drives the top ring 6 to move downward, the top ring 6 and the fixing ring 7 squeeze the hollow rubber elastic ring 8, and limit the upper and lower surfaces of the hollow rubber elastic ring 8, so that the hollow rubber elastic ring 8 moves to the The two sides expand and fit tightly against the outer wall of the straight tube 1 and the inner side of the fixing ring 7, thereby sealing the straight tube 1, and the sealing effect is relatively good; a rotating ring 9 is rotatably installed on the outer wall of the straight tube 1 and located below the fixing ring 7, and a connecting belt 10 connected to the cap 5 is fixed on the outer wall of the rotating ring 9, which facilitates the connection between the cap 5 and the straight tube 1 and avoids the loss of the cap 5, which is relatively practical; a sealing ring is fixed on the inner top wall of the cap 5, which is in sealing contact with the top of the straight tube 1, further increasing the sealing performance of the connection between the cap 5 and the straight tube 1, which is relatively complete.
