Wherein, for more stable snatching sampling pipe, first clamping face 2311 and second clamping face 2321 can be configured into the arcwall face with the outer wall complex of sampling pipe for the area of contact of first clamping face 2311 and second clamping face 2321 and sampling pipe is bigger, weak defect when avoiding snatching.

The configuration of the robot 200 is not limited to the above-described configuration, and the above-described embodiment is not to be construed as limiting the present application, and other robots 200 may be used to perform the operation of grasping the sampling tube, for example, four-axis, six-axis, eight-axis, and the like robots may be used.

Referring to fig. 3 and 5, the sampling tube rack 300 is provided with a plurality of tube slots 301, the tube slots 301 are used for fixing the sampling tubes, wherein the tube slots 301 can be configured to match with the outer diameter of the sampling tubes to prevent the sampling tubes from shaking in the tube slots 301, and further, in order to fix the sampling tubes, the sampling tubes can be relatively fixed with the tube slots 301 in an interference fit manner. In this embodiment, as shown in fig. 5, the sampling tube holder 300 has a substantially circular structure and has a loading surface 311, the tube slot 301 is opened on the loading surface 311, and the loading surface 311 is disposed substantially perpendicular to the direction in which the sample retention pins 20 are disposed, so that the sampling tube can be aligned with the sample retention pins 20 when the sampling tube is disposed in the tube slot 301. The sample retention needle 20 is aligned, that is, the axial direction of the sample retention needle 20 corresponds to the mouth of the sampling tube.

With reference to fig. 5, the plurality of tube slots 301 are arranged on the loading surface 311 in a circular array (i.e. a circular array), the sampling tube rack 300 includes a first driving device 320 and a loading platform 310, the loading surface 311 is formed on the loading platform 310, the first driving device 320 is used for driving the loading platform 310 to rotate (rotate), i.e. the first driving device 320 is used for driving the loading platform 310 to rotate around a central line perpendicular to the loading surface 311, during the rotation of the loading platform 310, the plurality of tube slots 301 rotate therewith, so as to adjust the positions of the tube slots 301, and further adjust the sampling tubes in the tube slots 301 to positions suitable for being grasped by the manipulator 200. I.e. the first driving means 320, as a driving mechanism for driving the loading station 310 to move and selectively move the sampling tube to the linear direction of the movement of the robot arm 200. Therefore, the manipulator 200 can grab the sampling tube fixed in the clamping groove 301 in the linear direction to complete puncture and sampling in the process of moving along the linear direction.

In this embodiment, when the loading platform 310 rotates, each tube slot 301 is selectively located in the extending direction of the slide rail 220, and is located on two opposite sides of the slide rail 220 from the sample retention needle fixing part 100. Like this manipulator 200's clamping part 230 is at the during operation, at first move to sampling pipe support 300 department along slide rail 220, snatch the sampling tube that is located slide rail 220 extending direction's tube seat 301, then along slide rail 220 towards leaving a kind needle fixed part 100 and remove, when removing the mouth of pipe that arrives the sampling tube and being located the needle 20 contact that leaves a kind of needle fixed part 100 that leaves a kind, continue to remove, it pierces through the mouth of pipe that the sampling tube and gets into in the sampling tube to leave a kind needle 20 this moment, because the sampling tube is the vacuum tube, under the effect of negative pressure, blood sample in the blood sampling bag enters into in the sampling tube through leaving a kind needle 20. When the collected blood sample reaches the preset volume, the manipulator 200 moves towards the direction of the sampling tube rack 300, the sample retention needle 20 is separated from the sampling tube, and when the manipulator 200 moves to the sampling tube rack 300, the sampling tube is placed into the tube groove 301 and then loosened, so that a sampling process is completed. When the sampling is required to be continued, the mechanical arm 200 is moved away first, the first driving device 320 drives the loading platform 310 to rotate, at this time, the next tube slot 301 moves to the extending direction of the slide rail 220, and the mechanical arm 200 clamps the sampling tube in the next tube slot 301 to perform the next sampling operation. And by parity of reasoning, the batched sampling work is completed.

In addition, in the process that the first driving device 320 starts to drive the loading platform 310 to rotate, the sampling tube which has completed sampling rotates along with the first driving device, the blood sample collected in the sampling tube can be shaken uniformly in the process that the sampling tube rotates, the blood sample is prevented from settling, coagulating and the like, and the subsequent tests of various physiological indexes are facilitated.

Further, as mentioned above, after the sampling is completed, the blood in the sampling tube can be used for detecting various physiological indexes, and in order to improve the detection quality, the blood in the sampling tube needs to be shaken, so that each component in the blood is in a relatively uniform state.
