Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, and in particular to an adapter for a sample injection rack of a biochemical immunoassay analyzer. Background Art

[0002] The sample holes of the injection rack of the biochemical immunoassay analyzer commonly used in the prior art are relatively large and fixed in size. Some are equipped with elastic supports to prevent the test tubes from shaking. However, the forces on the four sides of the supports are uneven, which can easily cause the small-diameter sample tubes to deviate from the center position. 1.5mL and 0.5mL centrifuge tubes are often used clinically. These sample tubes have small diameters and low heights and cannot be used directly on the injection rack. The samples must be transferred to a special sample cup, which makes it impossible to automatically scan the instrument. The LIMs two-way transmission is reduced to a one-way transmission, which increases the sample transfer link, increases the cost of consumables, and causes sample volume loss. It is not suitable for testing small samples or precious samples.

[0003] Therefore, it is necessary to provide an adapter for a biochemical immunoassay analyzer sample rack, which is used to fix sample tubes with small diameters and low heights, avoid sample volume loss due to sample transfer, and save costs. Summary of the invention

[0027] like Figure 1 As shown, an adapter for a biochemical immunoassay analyzer sample injection rack comprises an adapter positioning tube 1 and an adapter positioning ring 2 , wherein the adapter positioning ring 2 is arranged on the top of the adapter positioning tube 1 .

[0028] like Figure 2 As shown, the adapter positioning tube 1 includes a positioning tube body 11, a positioning tube positioning groove 14 and a positioning tube limiting ring 13. The positioning tube body 11 is tubular, and the positioning tube limiting ring 13 is horizontally wrapped around the outer wall of the positioning tube body 11. The positioning tube positioning groove 14 is arranged on the inner wall of the positioning tube body 11. A positioning tube opening 12 is provided on the side wall of the positioning tube body 11 along the axial direction of the positioning tube body 11.

[0029] The adapter positioning tube 1 can be embedded in the test tube slot of the biochemical immunoassay analyzer injection rack, and can position the sample tube in the center of the positioning tube positioning slot 14 to prevent deviation; the positioning tube limiting ring 13 protrudes outward from the outer wall of the positioning tube body 11 to limit the depth of the positioning tube body 11 embedded in the test tube slot of the injection rack. The positioning tube opening 12 is the sample barcode scanning area. Put the sample tube into the positioning tube positioning slot 14, and face the sample barcode toward the positioning tube opening 12, so that the instrument can scan the sample barcode, which is suitable for biochemical immunoassay analyzers of various brands.

The positioning ring groove 23 includes a groove side wall and a groove top wall, and the positioning ring inner ring 24 is arranged on the inner wall of the positioning ring body 21.

[0031] A positioning ring opening 22 is provided on the side wall of the positioning ring body 21 along the axial direction of the positioning ring body 21, and the positions of the positioning tube opening 12 and the positioning ring opening 22 correspond to each other. The positioning ring opening 22 has the same function as the positioning tube opening 12, and the positioning ring opening 22 is a sample barcode scanning area. When a small or micro centrifugal sample tube with a smaller tube diameter is placed in the positioning ring inner ring 24, and the sample barcode is directed toward the positioning tube opening 12 and the positioning ring opening 22, the instrument can scan the sample barcode.

[0032] The angle between the positioning tube opening 12 and the positioning ring opening 22 is 60 degrees. Such an angle design can not only position the sample tube firmly in the adapter without deviating from the center, but also display the barcode on the sample tube completely to achieve instrument scanning.

The inner diameter of the groove side wall of the positioning ring groove 23 is the same as the outer diameter of the positioning tube body 11, and the outer diameter of the adapter positioning ring 2 is the same as the outer diameter of the positioning tube limiting ring 13. The positioning ring groove 23 on the positioning ring body 21 is interference-fitted with the top outer side wall of the positioning tube body 11, so that the adapter positioning ring 2 and the adapter positioning tube 1 are tightly combined into one.

[0034] The inner diameter of the positioning ring inner ring 24 is smaller than the inner diameter of the positioning tube positioning groove 14. The inner diameter of the positioning ring inner ring 24 is smaller, so as to be suitable for positioning small and micro centrifugal sample tubes with smaller tube diameters.

[0035] The adapter positioning tube 1 can be used alone, and is suitable for positioning conventional sample tubes to prevent deviation from the center position; the adapter positioning ring 2 needs to be used in combination with the adapter positioning tube 1, and is suitable for small and micro centrifuge sample tubes with smaller diameters.
