When the automatic sample introduction unit works, on one hand, the moving mechanism 30 can drive the rotating mechanism 20 to move to the discharging position, so that, for example, the detected sample container 40 can be taken down from the sample tray 10, or the sample container 40 to be detected can be mounted on the sample tray 10, or of course, the sample tray 10 can be integrally detached, and the sample container 40 to be detected can be mounted on the sample tray 10; on the other hand, when the moving mechanism 30 is controlled to operate reversely, the moving mechanism 30 drives the rotating mechanism 20 to move to the warehouse entering position, so that the next detection operation can be carried out; in addition, because the sample tray 10 is provided with the plurality of mounting portions 11 which are sequentially arranged along the top surface edge at intervals and are used for mounting the sample containers 40, the sample liquids of the plurality of sample containers 40 can be respectively detected, the working efficiency is high, and simultaneously, under the rotation driving of the rotating mechanism 20, the positions of the sample containers 40 on the sample tray 10 can be adjusted, so that the preset sample containers 40 can be rotated to, for example, a blending station for blending treatment, and rotated to, for example, a scanning station for code scanning action. Therefore, the automatic sample feeding unit can improve the working efficiency, is convenient to operate, and can be beneficial to realizing the simultaneous detection of different projects.

Referring to fig. 1 to 3, in one embodiment, the mounting portion 11 is, for example, a slot capable of receiving and positioning the sample container 40, and the sample container 40 is positioned by being inserted into the slot, and the position of the sample container can be adjusted by rotating or linearly moving along the horizontal direction along with the sample tray 10 after positioning; when the sample container 40 needs to be replaced, the sample container 40 is directly pulled out from the slot.

The base 51 and the moving mechanism 30 are mounted on a rack, a floor or a table of a workbench, and the rotating mechanism 20 is mounted on the slide rail 52. The moving mechanism 30 is connected to the rotating mechanism 20 through a slide rail 52, and the moving mechanism 30 is used for driving the slide rail 52 to slide on the base 51. Therefore, when the moving mechanism 30 works, the moving mechanism 30 drives the sliding rail 52 to slide on the base 51, and the sliding rail 52 correspondingly drives the rotating mechanism 20 to move, so that the moving mechanism 30 can more stably drive the rotating mechanism 20 to move, and the operation effect is more stable.

The connecting member 341 can move to the position of the second correlation sensor 72 while driving the slide rail 52 to move, and can shield the emitted light of the second correlation sensor 72, so that the second correlation sensor 72 can sense the connecting member 341 and can acquire the specific moving position of the connecting member 341 when sensing the connecting member 341, that is, can acquire the moving position of the sample tray 10 along the sliding direction of the slide rail 52, and for example, calibrate the position at this time as the initial position, so that the moving position of the sample tray 10 along the sliding direction of the slide rail 52 can be controlled more accurately. Of course, the second calibration component 70 may also be a sensing device such as a proximity switch, etc., as long as it can be used for calibrating the moving position of the sample tray 10 along the sliding direction of the slide rail 52, and is not particularly limited herein.

Referring to fig. 1 to 3, in one embodiment, the sample tray 10 is detachably mounted on the rotating mechanism 20.

Referring to fig. 1 to 3, in one embodiment, the sample tray 10 further includes a holding portion 12 at a middle portion thereof. Thus, the sample tray 10 can be easily carried by holding the grip 12 with the hand, and the operation is easy.

Referring to fig. 1 and 4, in one embodiment, the automatic sample injection unit further includes a housing 80. The housing 80 is provided outside the rotating mechanism 20. In this way, the housing 80 can prevent the rotating mechanism 20 from being exposed, and protect the rotating mechanism 20.

The specific example disclosed in the drawings of the present embodiment is three rollers 23, but other numbers and arrangements are certainly possible, and the present invention is not limited herein and is set according to the actual situation. When the rotating mechanism 20 moves to the egress position, the roller 23 is used to interfere with the hatch door of the medical detection device to push the hatch door outward. Therefore, in the process that the rotating mechanism 20 moves outwards to leave the cabin, the rotating mechanism is abutted against the cabin door through the rollers 23 and pushes the cabin door outwards, and therefore damage to the cabin door can be reduced. Specifically, when the rotating mechanism 20 is further provided with the housing 80, the roller 23 penetrates the housing 80 and protrudes outside the housing 80.

In one embodiment, a medical testing device comprises the autosampler unit of any of the above embodiments.
