Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is useful for automatic analyzers such as biochemistry analyzers and hematology analyzers. This relates to a sample rack that is transported while holding several sample containers. Sample rack The container holds multiple sample containers and is transported along a belt line, etc., and then The sample is dispensed from the sample container into the reaction container.

0002

[Conventional technology]

Used in facilities that use automated analyzers such as biochemistry analyzers and blood analyzers. Sample containers, such as sample cups and blood collection tubes, may vary depending on the purpose of analysis and the amount of sample collected. There are various types. Therefore, the analyzer may limit the sample containers that can be used, or The rack also depends on the sample container, for example, for a 2ml cup, 13mm in diameter x 75m in depth. Dedicated specimens such as 16 mm diameter x 100 mm deep blood collection tubes. We are responding by creating a rack.

[Problem that the idea aims to solve]

The sample rack has only one size of sample holding holes, so It is very difficult to use different sample racks depending on the samples that come in during routine laboratory work. It is complicated. In addition, in some cases, sample containers may only be held in a portion of the sample rack. Sample racks may be transported in a state where the Ru. In addition, if the analyzer is systematized, it should be removed from the host computer. It is necessary to perform the analysis according to the worksheet provided, so place the sample in the sample container that was in the sample rack. Samples may have to be transferred manually from blood collection tubes, which can prevent sample mix-ups. Which mistakes are likely to occur? This invention allows one type of sample rack to easily accommodate various sample containers. The purpose is to provide a sample rack that can

[Means to solve the problem]

The sample rack of the present invention has a circular cross section for holding sample containers, and is vertically oriented. Multiple holes are provided with equal diameter, and the front side of each hole is marked with the smallest diameter of the sample container to be used. A cut is made from the top edge to the bottom of the hole with a width smaller than the diameter of the object. A leaf spring is provided that pushes the sample container in the direction of the cut.

【Example】

Figure 1 shows a sample rack of one embodiment, (A) is a partial front view, and (B) is its X- FIG. 3 is a cross-sectional view at an X-ray position. Figure 2 shows the sample rack of the same example holding blood collection tubes. (A) is a partial plan view, (B) is a partial front view, ( C) is a sectional view taken along line Y-Y in (A). The sample rack 2 has a vertical section with a circular cross section to hold blood collection tubes as sample containers. A plurality of perpendicular holes 4 are provided, and the diameters of each hole 4 are set to be equal. A notch 6 is provided on the front surface of the hole 4 over the length from the top of the hole 4 to the bottom of the hole. The width of this cut 6 is smaller than the diameter of the smallest blood collection tube used. width is set. Push the blood collection tube inserted into the hole 4 in the direction of the notch 6 to secure it. A leaf spring 8 is provided for determining the position. The upper end of the leaf spring 8 is fixed to the upper end of the hole 4. The lower end of the leaf spring 8 is provided in the hole 4 so that it can expand and contract in a directional manner. It is adapted to move along the guide groove 10.

[0006] The diameter of blood collection tubes commonly used in testing laboratories ranges from 13 to 16 mm. It belongs to the surrounding area. The state in which the blood collection tube is inserted into the hole 4 is shown in FIG. straight Blood collection tubes 12a to 12c with different diameters are each cut in each hole 4 by a leaf spring 8. It is pressed in the direction of 6 and is held fixed. The blood collection tubes 12a to 12c are A barcode label is attached that displays the body number and measurement items. hole cut Step 6 reads the barcode labels affixed to the blood collection tubes 12a to 12c. It also serves as a window for reading with a reading device. Position S in Figure 2 is below the sample nozzle. Indicates the descending position.

[0007] If you use a blood collection tube with a diameter in the range of 13 mm to 16 mm, Set the size of hole 4 of sample rack 2 to be slightly larger than 16 mm in diameter. The incision 6 is set to have a width narrower than the diameter of the smallest blood collection tube, 13 mm.

[0008]

[Effect of the idea]

In the sample rack of this invention, all holes for holding sample containers are set to the same diameter. However, a cut smaller than the diameter of the smallest sample container is made on the front surface, and the sample container is placed inside the hole. A leaf spring that presses in the direction of the cut is installed, so it can be used in inspection rooms with different diameters. You will be able to set up all blood collection tubes. Therefore, as before A procedure such as manually dispensing from a blood collection tube into a sample cup of the size that matches the sample rack. This eliminates the need for manual labor and reduces human error. Even when performing specimen recognition using barcodes, blood collection tubes are fixed with leaf springs. Since it does not rotate inside the hole, it prevents reading errors by barcode readers. Can also be done.
