Description

Sample tube storage support and sample analyzer

Technical Field

The invention relates to the field of sample analysis of in-vitro diagnosis, in particular to a sample tube storage bracket and a sample analyzer using the same.

Background

With the rapid development of medical technology, medical examination has become one of indispensable diagnostic tools, and according to the items to be examined, the samples are allocated to the corresponding sample tubes, the sizes and weights of the sample tubes of different models are different, and as the number of the sample tubes stored on the sample tube carrier increases, the weight of the sample tube carrier also increases, which is not convenient for taking the sample tube carrier. The conventional sample tube carrier does not have a holding part, and the movement of the whole sample tube carrier is not convenient.

Furthermore, in order to mark the position of the sample tube, the sample tube carrier is usually provided with a label, which may be a two-dimensional code or a bar code. The position information of the sample tube can be obtained by scanning the label by the scanner of the sample analyzer, i.e. knowing in which slot of the sample tube carrier the sample tube is located. However, when a commercially available sample tube carrier is scanned, a failure that positional information cannot be read may occur.

The slot 21 has an opening 211 formed in a wall thereof.

In the embodiment of the present invention, the slot 21 may fix not only the sample tube, but also an adapter adapted to a specific sample tube, and the label of the sample tube is exposed from the opening 211 so as to read or scan the label, thereby obtaining the detection information of the sample tube.

The bracket handle 3 is a hollow injection structure to reduce the overall weight of the sample storage bracket. The bracket handle 3 further comprises a plurality of reinforcing blocks 32 which are arranged along the bracket handle 3, and the reinforcing blocks 32 are matched with the shape of the connecting part of the bracket handle 3. By providing the reinforcing block 32, the load-bearing capacity of the bracket handle 3 can be improved.

The height of the sample holder 2 is approximately two thirds of the height of the holder handle 3. The rack handle 3 has a rectangular basic shape. In the rectangular contour a C-shaped opening 31 is provided. The open portion of the C-shaped opening faces the side of the rack handle 3 remote from the sample rack 2. The grip portion is formed by the C-shaped opening, and thus a user can grip the sample tube storage rack.

The open portion of the C-shaped opening 31 extends downwardly from one half of the side of the bracket handle. Since the side is a long side of the rectangle, such a structure provides a user with accurate holding positioning and sufficient holding space. When holding the rack handle 3, the user's fingers can be held exactly at the upper half of the side of the handle.

In the conventional O-shaped handle, the user may directly grip the lower half of the side edge when gripping, which may cause the sample tube to tip over when the sample tube storage rack is fully loaded with the sample tube due to the risk of insufficient gripping force of the sample tube or excessive force when lifting.

Here, the half and two-thirds are approximate numbers, and may be located above or below one-half of the side of the rack handle, or may be located above or below two-thirds of the height of the rack handle 3. The structure of the bracket handle of the device accords with human physical engineering, and the hollow injection molding structure reduces the weight of the device.

Further, as shown in fig. 1, a scanning channel 11 is disposed between the sample rack 2 and the rack handle 3, and the width of the scanning channel 11 is at least greater than the widths of the two slots 21.

In the embodiment of the invention, when the sample tube storage rack is placed in the sample bin, the scanning channel 11 is matched with the scanning window on the sample bin for placing the sample tube storage rack, and the scanner scans the sample label and the position label on the sample tube storage rack through the scanning window and the scanning channel 11 of the placed sample tube storage rack. The width of the scanning channel 11 is at least larger than the widths of the two slots 21, so that the scanning range of the scanner is wide enough, and the situation that the scanner misses scanning sample labels on the sample tube storage bracket due to the fact that the scanning channel 11 is too narrow is avoided.

Alternatively, as shown in fig. 1, the bottom of the slot 21 is a hemispherical recess matching with the bottom of the sample tube.

The sample tube, which does not match the size of the insertion slot 21, is fixed to the sample holder 2 by an adapter that matches the sample tube. The bottom of the sample tube is matched with the slot 21 so that the sample tube is stably fixed on the sample rack 2.

In the embodiment of the present invention, the inner wall of the slot 21 is provided with a fixing device 22 for fixing the sample tube, and when the sample tube 4 is inserted into the slot 21, the sample tube passes through the fixing device 22 and is vertically fixed on the sample rack 2.

Optionally, as shown in fig. 3, the fixing device 22 is a plurality of elastic pieces, the elastic pieces are uniformly distributed along the inner wall of the slot 21, and the lower ends of the elastic pieces tilt toward the center of the slot 21 to form a diameter reduction portion inside the slot 21.

In an embodiment of the present invention, the fixing device 22 employs a plurality of elastic pieces uniformly distributed in a circular shape along the inner wall of the slot 21, and the diameter of a virtual circle formed at the lower part of the elastic piece is smaller than the diameter of the slot. When the sample tube is inserted into the insertion slot 21, the tube body of the sample tube is fixed to the sample tube storage rack by the fixing device 22. In the embodiment of the invention, the diameter of the virtual circle formed by the lower end of the elastic sheet on the inner wall of the slot 21 is smaller than that of the sample tube, and when the sample tube penetrates through the virtual circle formed by the elastic sheet and is inserted into the slot 21, the diameter of the virtual circle is smaller than that of the sample tube, so that the tube body of the sample tube generates acting force on the elastic sheet and simultaneously receives the reverse acting force of the elastic sheet, and the sample tube is fixed more firmly. In some embodiments, the elastic sheet is a plastic elastic sheet, and in other embodiments, the elastic sheet is made of metal, which can be selected according to actual requirements. Fig. 3 is only one embodiment of the present invention and should not be construed as limiting the fixation device 22.
