Description

Technical Field

[0001] The utility model relates to the technical field of medical electronic equipment, in particular to an automatic sample rack transport device. Background Art

[0002] With the development of modern medical device technology, fully automatic transmission of samples has been widely used in testing instruments. Taking the chemiluminescent immunoassay analyzer as an example, the traditional sample introduction device mainly relies on the track to drive the sample rack to move, completing the sample rack injection, identification, code scanning, sampling, and sample output process. However, in actual use, the sample rack is prone to shaking due to unstable track transmission, causing the sample to be tested to spill out of the sample tube due to inertia, thereby contaminating the sample introduction device.

[0003] Moreover, the tracks will become loose after running for a period of time, causing the sample rack to be transmitted at an uneven speed during the transmission process, causing the originally horizontal sample rack to slowly tilt, making it impossible for the sample rack to be sent horizontally into the scanning area for identification, causing a malfunction, and causing the instrument to report an error and pause, which is not conducive to the smooth progress of the detection work. Utility Model Content

[0004] The utility model aims to provide a sample rack automatic transport device to solve the above-mentioned deficiencies of the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A sample rack automatic transport device comprises a sample introduction component, a basket lifting component and a blocking component;

[0007] The sample injection assembly comprises a base, a carrying track and a carrying trolley arranged on the base;

[0008] The basket assembly comprises a basket body and a handle, the basket body is provided with a plurality of sample channels with one end open, the sample rack is placed in the sample channel and can enter and exit the sample channel;

[0009] The blocking assembly includes a baffle plate with one end arranged at the opening of the sample channel and capable of limiting the position of the sample rack, and a pressing plate connected to the other end of the baffle plate;

[0010] The pressing plate is rotatably connected to the bottom surface of the basket body through a rotating mechanism; the rotating mechanism can drive the baffle to rotate in a direction away from the opening, so that the sample rack can be taken out from the opening;

[0011] The base is provided with a basket body placement area, a positioning block and a fixing spring are provided in the placement area, and a positioning hole is provided on the basket body at a position corresponding to the positioning block.

[0012] Furthermore, the rotating mechanism is a rotating shaft, the bottom surface of the basket body is provided with a space for accommodating the pressure plate, and the positioning block can be inserted into the positioning hole and abut against the pressure plate.

[0013] Furthermore, limit blocks are arranged on the left and right sides of the placement area of ​​the basket body, the positioning block is fixed on the limit blocks, and the fixing spring is installed on the inner wall of the limit block to clamp the basket body.

[0014] It can be seen from the above technical scheme that the utility model installs a blocking component at the lower part of the basket body, which can effectively fix the position of the sample rack and prevent the sample rack from shaking during the transportation of the basket; at the same time, the closing of the baffle on the blocking component is controlled by the gravity of the basket body itself. When the pressure plate of the blocking component is pressed on the positioning block, the baffle can be opened downward with the rotating shaft as the center, providing a passage for the transportation of the sample rack, and can be reset by a torsion spring; while ensuring the transportation efficiency, the spatial layout of the instrument transportation device is reduced, and the instrument production cost is reduced.

[0021] A preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1 The sample rack automatic transport device shown includes a sample introduction component, a basket assembly and a blocking component. Specifically, the sample introduction component includes a base 1, a transport track 2 and a transport trolley 3 arranged on the base.

[0023] like Figure 2As shown, the basket assembly includes a basket body 4 and a handle 5. The basket body 4 is provided with a plurality of sample channels 6 with one end open. The sample rack is placed in the sample channel 6 and can enter and exit the sample channel 6. The basket body 4 described in this preferred embodiment is provided with ten sample channels 6. Each sample rack can hold five sample tubes and can carry a large number of samples to be tested at one time.

[0024] like Figure 3 As shown, the blocking assembly includes a baffle 7 with one end arranged at the opening of the sample channel 6 and capable of limiting the sample rack, and a pressure plate 8 connected to the other end of the baffle 7; the pressure plate 8 is rotatably connected to the bottom surface of the basket body 4 through a rotating mechanism 10; the rotating mechanism 12 can drive the baffle 7 to rotate in a direction away from the opening, so that the sample rack can be taken out from the opening; at the same time, when the pressure plate 8 is not subjected to external force, the baffle 7 can limit the sample rack through the rotating mechanism 9 and its own gravity; the rotating mechanism 9 described in this preferred embodiment is a rotating shaft, and the bottom surface of the basket body 4 is provided with a space for accommodating the pressure plate 8.

[0025] The base 1 described in the preferred embodiment is provided with a basket body placement area, in which a positioning block 10 and a fixing spring 11 are provided. A positioning hole is provided on the basket body 4 at a position corresponding to the positioning block 9, and the positioning block 10 can be inserted into the positioning hole and abut against the pressure plate 8.

[0026] like Figure 4 and 5 As shown, U-shaped limit blocks are arranged on the left and right sides of the placement area of ​​the basket body described in this preferred embodiment, the positioning block 10 is fixed to the inner bottom surface of the limit block, and the fixing spring 11 is installed on the inner wall of the limit block to clamp the basket body from the front and rear directions.

[0027] In specific use, the inspector first manually places the sample tube on the sample rack, and then puts the sample rack into the sample channel 6 of the basket body 4 in turn. The baffle plate 7 of the blocking assembly limits the sample rack to ensure the stability of the sample rack and prevent the sample tube from tilting and causing the sample to overflow. Then, the inspector holds the handle 5 of the basket assembly 4 to keep the basket body 4 in a horizontal state and slowly places the basket body 4 in the basket parking area. During the lowering process, the basket body 4 slowly presses against the fixing spring 11, so that the basket body 4 is fixedly clamped in the basket parking area. At the same time, the pressure plate 8 is affected by gravity and conflicts inward with the positioning block 9 of the basket parking area, so that The pressing plate 8 drives the baffle plate 7 to rotate in a direction away from the opening with the rotating shaft as the rotation center, so that the sample rack can be taken out from the opening; the sample to be tested enters the transport trolley 3 along with the sample rack, and the transport trolley 3 transports the sample to be tested to a designated position on the transport track 2. After the sample information is read and the sample is sampled, the sample is transported back to the basket body 4 by the transport trolley 3 to complete the entire automatic sampling process; after the basket body 4 is taken out from the basket parking area, the pressing plate 8 resets the baffle plate 7 through the rotating shaft under the action of its own gravity, and restores the limiting function of the sample rack; the above process is repeated to achieve efficient transportation of the sample to be tested.

[0028] The above-described embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
