The pretreatment mechanism includes a vortex oscillator and a centrifuge, wherein the vortex oscillator is located on one side of the detection body, the cooling structure is located between the vortex oscillator and the oven and is connected to the detection body, the centrifuge is located between the oven and the sampling platform, the sample loading area is located on the side of the detection body away from the vortex oscillator, and the detection structure is located below the sample loading area.

[0003] In the above scheme, the test paper is placed in the test paper slot for detection, but only one detection can be performed at a time, and multiple detections cannot be performed, so there is no detection alignment group, resulting in reduced detection accuracy. To this end, a tumor fluorescence tomography detection device is proposed. Utility Model Content

[0004] The utility model aims to solve the problems raised by the background technology and provides a tumor fluorescence tomography detection device.

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

[0006] A tumor fluorescence tomography detection device comprises a base, a test tube oscillator is fixedly provided on one side of the top of the base, and a detection mechanism is provided on the other side of the top of the base; the detection mechanism comprises a containing tube, a liquid outlet pipe and a turntable, a bracket is fixedly provided on the top of the base, the containing tube is fixedly provided on the top of the bracket, the liquid outlet pipe is fixedly provided on the bottom of the containing tube, and a switch valve is provided on the tube wall of the liquid outlet pipe, the turntable is horizontally located below the containing tube, and the bottom center of the turntable is rotatably connected to the top of the base through a rotating shaft, and a limiting mechanism is provided on one side of the turntable; a plurality of evenly distributed test paper placement tables are fixedly provided at the top edge of the turntable.

[0007] Preferably, the limiting mechanism includes a U-shaped plate, a limiting rod, a first spring and a limiting ring, the U-shaped plate is fixedly arranged on the top of the base, the limiting rod is vertically inserted in the top of the U-shaped plate, the first spring is arranged on the rod wall of the limiting rod, the limiting ring is fixedly arranged on the side wall of the turntable, and the upper end of the limiting rod is plugged into the limiting ring.

[0008] Preferably, there are multiple limit rings, and the positions of the multiple limit rings are arranged in a one-to-one correspondence with the positions of the multiple test paper placement tables.

[0009] Preferably, the limiting rod is a T-shaped rod.

[0010] Preferably, the test paper placement table includes a fixed table and a movable table, and test paper placement grooves are provided on opposite sides of the fixed table and the movable table, the bottom of the fixed table is fixedly connected to the top of the base, and installation grooves are provided on opposite sides of the fixed table and the movable table, and the same telescopic rod is fixedly provided between the insides of the two installation grooves, and a second spring is provided on the rod wall of the telescopic rod, and the two ends of the second spring are respectively fixedly connected to the side walls of the two installation grooves.

[0011] Preferably, the plurality of test paper placement tables can be rotated to the bottom of the liquid outlet tube in sequence.

[0012] Compared with the prior art, the utility model provides a tumor fluorescence tomography detection device, which has the following beneficial effects:

[0013] 1. The tumor fluorescence tomography detection device is provided with a containing tube, a liquid outlet pipe, a turntable, a switch valve, a rotating shaft and a test paper placement table. When the switch valve is opened, the sample inside the containing tube is discharged through the liquid outlet pipe and drips onto the test paper inside the test paper placement table, thereby enabling tumor fluorescence tomography detection. At the same time, the turntable can rotate around the rotating shaft, so that multiple test paper placement tables are rotated to the bottom of the liquid outlet pipe in turn, thereby enabling multiple groups of test paper detection, and facilitating control detection, thereby improving the accuracy of detection.

[0014] 2. The tumor fluorescence tomography detection device is provided with a U-shaped plate, a limit rod, a first spring and a limit ring. Since the position of the turntable is movable, the first spring applies elastic force to the limit rod so that the upper end of the limit rod is inserted into the interior of the limit ring, which can limit the position of the turntable and increase the stability of the test paper placement table.

[0015] 3. The tumor fluorescence tomography detection device is provided with a fixed table, a movable table, a test paper placement slot, a telescopic rod and a second spring. The test paper can be placed in the test paper placement slots on the fixed table and the movable table. When the test paper needs to be taken out, it is only necessary to pull the movable table so that the telescopic rod and the second spring are stretched. At this time, the test paper placement slots on the fixed table and the movable table are separated, thereby facilitating the removal of the test paper. After the test paper is taken out, the external force on the movable table is released. At this time, the elastic force of the second spring causes the fixed table and the movable table to merge.

[0016] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model can perform multiple groups of sample detection and can perform comparative detection to improve the accuracy of detection. BRIEF DESCRIPTION OF THE DRAWINGS
