Description

Technical Field

[0001] The utility model relates to the technical field of laboratory sample processing, and particularly relates to a pre-processing adapter turntable for a laboratory. Background Technique

[0002] At present, before a hospital conducts a blood test on a clinical patient, it is necessary to first centrifuge a blood specimen using a centrifuge, which is a conventional medical device. A number of test tube jacks are provided on the adapter of the centrifuge. After inserting the test tube containing the blood specimen into the test tube jack of the adapter, and then loading the adapter into the centrifuge, the blood specimen can be centrifuged.

[0003] In existing laboratory pre-processing systems, similar functional modules such as the adapter storage function, adapter transfer function, sample tube balancing and problem sample tube storage function are often independent of each other. Therefore, when using a centrifuge, multiple devices are required, which occupies a large space and is not convenient for taking and placing the adapter or sample tube. At the same time, it takes a certain amount of time to transfer and adjust the adapter between the devices corresponding to each functional module and the centrifuge, and the pre-processing work efficiency is not high. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, a pre-processing adapter turntable for a laboratory is now proposed, which solves the problems of using multiple devices when using a centrifuge in the above background technique, occupying a large space, and being inconvenient for taking and placing the adapter or sample tube.

[0005] To achieve the above object, the present utility model proposes the following technical solutions for implementation:

[0011] Further, each group of limiting posts includes two limiting posts symmetrically arranged with respect to the adapter storage position, and a sample tube bracket is provided at the sample tube storage position for storing balanced sample tubes or problematic sample tubes.

[0012] Further, a driving assembly is further included. The driving assembly includes a driving motor fixed on the mounting plate, and a driving wheel rotatably connected to the mounting plate and fixed to the turntable bottom plate. The driving motor is in transmission connection with the driving wheel.

[0013] Further, a guide roller is provided on the mounting plate. A guide groove is provided on the roller surface of the guide roller, and a guide rail is provided on the inner side of the driving wheel. The guide rail is engaged with and in rolling connection with the guide groove.

[0026] A turntable structure is set up. The rotation of the turntable drives the adapter to rotate, enabling the storage of the adapter and the simultaneous allocation of its position in two functional areas. The structure is compact. The adapter turntable can not only store the adapter 2, but also adjust the position of the adapter 2 through rotation, facilitating the cooperation with the robotic arm to place the adapter on it into the centrifuge, or take the adapter in the centrifuge and place it on the turntable, or rotate the empty adapter 2 to the position for receiving the sample tube, and transfer the adapter 2 after centrifugation to the sample tube download position for subsequent processes, realizing the storage, picking up, and transfer of the adapter 2 while rotating. It can also store the balancing sample tube and the problem sample tube through the sample tube storage position, achieving multiple functions with a relatively small volume. A placement opening 3 leading directly to the centrifuge is opened at the center of the turntable bottom plate 1. The adapter 2 can be taken out from the adapter storage position and then pass through the placement opening 3 to reach directly above the center of the turntable bottom plate 1 to the centrifugation working position, shortening the time and space for the adapter 2 to reach the centrifugation working position and improving the pre-processing efficiency.

[0027] Preferably, positioning columns are also provided on the turntable bottom plate 1, such as Figure 3 shown. The positioning columns are arranged within the adapter storage position, fixed in a conical shape above the turntable bottom plate 1.

[0028] This application can be but is not limited to being applied in the laboratory pre-processing system, realizing the storage and transfer of the centrifuge adapter 2, the function of receiving the sample tube, and the storage functions of the problem sample tube and the balancing sample tube, and preparing for the sample centrifugation and subsequent processes after centrifugation in the laboratory pre-processing system.

[0029] In the laboratory pre-processing adapter turntable of this embodiment, the first limiting component includes a limiting plate 4 arranged above the turntable bottom plate 1, and a clamping groove matching the shape of the adapter 2 is opened on the limiting plate 4.

[0037] In the laboratory preprocessing adapter turntable of this embodiment, the limit column group includes two limit columns 5 symmetrically arranged about the adapter storage position, and a sample tube holder 6 is provided on the sample tube storage position to store balancing sample tubes or problem sample tubes, and the storage and retrieval function is realized by cooperating with the rotation of the turntable bottom plate 1.

[0038] Specifically, the snap-in groove and the limiting column 5 are not in direct contact with the adapter 2, and a gap of 1-2 mm is left between the two and the adapter 2 to prevent over-positioning. Preferably, the top of the limiting column 5 is set as a smooth semicircular head.

In this embodiment, three guide rollers 10 are arranged and distributed in an array along the center of the through hole, so as to provide rotation support for the driving wheel 9 while making the driving wheel 9 evenly stressed and maintaining stable rotation.

[0044] Preferably, the guide roller 10 is composed of a bearing and a mounting seat, wherein two guide rollers 10 are fixed on the mounting plate 7 through the mounting seat, and one guide roller 10 can adjust the distance from the center of the opening of the mounting plate 7 through the corresponding waist-shaped grooves on the mounting seat and the mounting plate 7 to ensure the meshing effect of the guide rail 11 and the guide groove.

[0045] In the laboratory pretreatment adapter turntable of this embodiment, a positioning assembly is provided on the mounting plate 7, and the positioning assembly includes a position sensor 12 fixed on the mounting plate 7, and the position sensor 12 is used to sense the positioning column 13 fixed on the turntable bottom plate 1 to determine the position of the turntable bottom plate 1.

The first position sensor is located on the inside to detect the positioning column 13 installed on the inner side of the turntable base plate 1 to determine the rotation angle of the turntable, and then determine the position of the adapter 2. The second position sensor is located on the outside to detect the positioning strip installed on the edge of the turntable base plate 1. The positioning strip is set individually, which is equivalent to the zero point of the turntable, so as to facilitate the calibration of the turntable.

[0048] The positioning component is set to detect and locate the important positions of the adapter turntable during the working process, ensuring that the adapter turntable rotates to the correct position and ensuring reliable operation.
