[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model embodiment discloses a pipette for medical examination.

[0027] The utility model provides Figure 1-4 The medical test pipette shown in the figure comprises a pipette body 1 and a plurality of first pipette tubes 2 and second pipette tubes 3 connected and arranged at the bottom of the pipette body 1, wherein the first pipette tube 2 is a hard plastic tube, and the second pipette tube 3 is a soft tube. A bottom plate 4 is fixedly arranged at the bottom of the pipette body 1, and the bottom plate 4 is slidably sleeved on the outer sides of the plurality of first pipette tubes 2 and second pipette tubes 3, and the pipette openings of the first pipette tube 2 and the second pipette tube 3 are both connected and provided with a suction head 5, and a vertical rod 6 is fixedly arranged at the bottom of the bottom plate 4, and the rod wall of the vertical rod 6 is rotatable. A rotating plate 7 is sleeved, and an adjustment mechanism for adjusting the position of the nozzle of the second pipette 3 is provided between the rotating plate 7 and the second pipette 3. The adjustment mechanism includes a telescopic rod 8, which is fixedly connected to the rotating plate 7. A guide block 9 is fixedly provided at the end of the telescopic rod 8. The guide block 9 is L-shaped and fixedly sleeved on the outside of the second pipette 3. Two symmetrically arranged guide grooves 10 are provided at the bottom of the bottom plate 4. The second pipette 3 is located in the guide groove 10, and the end of the guide block 9 is slidably arranged in the guide groove 10.

[0028] When the pipette body 1 is in use, initially, multiple first pipettes 2 and second pipettes 3 are symmetrically arranged with the suction heads 5 at the four corners. At this time, the liquid in the rectangular position can be pipetted. When it is necessary to transfer multiple liquids in the horizontal position, the rotating plate 7 can be rotated under the support of the vertical rod 6. Under the connection of the telescopic rod 8, the guide block 9 can be pushed and drive the pipette mouth of the second pipette 3 to move under the sliding limit of the guide groove 10. Since the telescopic rod 8 has stable elasticity, the guide block 9 can drive the second pipette 3 to move stably. When the pipette mouths of the multiple first pipettes 2 and the second pipette 3 are horizontally arranged, the position of the rotating plate 7 can be fixed, so that the positions of the multiple suction heads 5 can be determined, thereby ensuring stability during the pipetting process.

[0029] In order to fix the position of the rotating plate 7 before and after the rotating plate 7 rotates, Figure 2-3 As shown, a rotation positioning mechanism for determining the position of the rotating plate 7 is provided between the rotating plate 7 and the base plate 4, and the rotation positioning mechanism includes a positioning rod 11, and a plurality of positioning grooves 12 which are symmetrically arranged in a surrounding manner are provided at the bottom of the base plate 4. The positioning rod 11 is slidably arranged in the rotating plate 7, and the end portion is inserted into the positioning groove 12. An operating ring 14 is hingedly provided at one end of the positioning rod 11 away from the positioning groove 12, and a spring 13 is provided on the rod wall of the positioning rod 11, and the two ends of the spring 13 are respectively fixedly connected to the positioning rod 11 and the rotating plate 7.

[0030] When it is necessary to adjust the position of the second pipette 3, the positioning rod 11 can be pulled through the operating ring 14, so that the positioning rod 11 is away from the positioning groove 12 and the spring 13 is stretched. At this time, the rotating plate 7 can be rotated without restriction. After the positions of multiple suction heads 5 are adjusted, the operating ring 14 is released, so that the positioning rod 11 quickly rebounds and is inserted into the positioning groove 12 under the elastic force of the spring 13, thereby completing the position fixation of the rotating plate 7, ensuring that the positions of the nozzles of multiple first pipettes 2 and second pipettes 3 do not change during the pipetting process, thereby improving the pipetting stability.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
