When a lifting mechanism moves a trace element detector 5 into the storage box 1, a protective plate 3 at its upper end protects the inside of the moving cavity, thus protecting the interior of the storage box 1. A moving cavity is located on the upper side of the storage box 1, and the protective plate 3 is snapped into the inside of the moving cavity. A lifting mechanism is fixed to the rear end inside the storage box 1, and a vertical plate 4 is fixed to the front end of the lifting mechanism. The upper side of the vertical plate 4 is fixedly connected to the lower side of the protective plate 3. The interior of the vertical plate 4 is provided with a clamping mechanism.

In this application, the specific process and detection system technology of how the trace element detector 5 detects blood are not described in detail. This part of the technology is a conventional technical means in this field. Waste liquid collection box 9 is fixed at the lower end of the inside of the storage box 1. A moving tube 10 is slidably connected to the upper side of the waste liquid collection box 9. A collection cover 11 is fixed to the upper side of the moving tube 10. A discharge tube 12 is fixed to the left side of the waste liquid collection box 9.

[0022] Symmetrical mounting blocks 15 are fixed to the front side of the disassembly cover 2. The side walls of the two mounting blocks 15 are threaded with mounting bolts. The mounting blocks 15 are fixedly connected to the front side of the storage box 1 by the mounting bolts. When it is necessary to repair the equipment inside the storage box 1 or to install or disassemble some structural components, it is necessary to open the disassembly cover 2.

[0023] The lifting mechanism includes a strip plate 16, the rear side of which is fixedly connected to the rear end of the inner wall of the storage box 1. A lead screw 17 is rotatably connected inside the strip plate 16 via a bearing. A first motor 18 is fixedly fixed to the upper side of the strip plate 16. The upper end of the lead screw 17 is fixedly connected to the output end of the first motor 18. A lifting block 19 is threadedly connected to the rod wall of the lead screw 17. The side wall of the lifting block 19 is slidably connected to the inner wall of the strip plate 16. A symmetrical fixing rod 20 is fixed to the front side of the lifting block 19. The front end of the symmetrical fixing rod 20 is fixedly connected to the rear side of the vertical plate 4. The first motor 18 is a forward and reverse motor. The first motor 18 drives the lead screw 17 at the output end to rotate. The lead screw 17 drives the lifting block 19 threadedly connected to the rod wall to move. The lifting block 19 drives the fixing rod 20 to move. The fixing rod 20 drives the vertical plate 4 to move. Thus, the vertical plate 4 drives the trace element detector 5 to move.

[0024] The clamping mechanism includes two movable blocks 21. The front side of the vertical plate 4 is provided with symmetrical sliding grooves. Both movable blocks 21 are slidably connected inside the sliding grooves. Springs 22 are fixed to the side walls of both movable blocks 21.

The upper end of the telescopic cylinder 27 is fixedly connected to the lower side of the second fixed block 26. The moving mechanism can drive the upper collection cover 11 to move upward, so that the collection cover 11 moves to the outside of the detection head 6, which is convenient for collecting disinfectant. The disinfectant can also be sprayed out through the disinfection nozzle 35 inside the collection cover 11 to sterilize and disinfect the detection head 6.

[0026] A sealing mechanism is fixed to the side wall of the collection hood 11. The sealing mechanism includes a fixing box 28, which is fixedly connected to the left side of the collection hood 11. A second motor 29 is fixed inside the fixing box 28. A rotating rod 30 is fixed to the output end of the second motor 29. A mounting bracket 31 is fixed to the upper end of the rotating rod 30. A sealing plate 32 is fixed to the right side of the mounting bracket 31. The sealing plate 32 is slidably connected to the upper side of the collection hood 11. In order to prevent the disinfectant and the blood after testing inside the waste liquid collection box 9 from emitting an unpleasant odor, when the device is not needed, the rotating rod 30 at the output end can be rotated by the second motor 29. The rotating rod 30 drives the mounting bracket 31 at the upper end to rotate. The mounting bracket 31 drives the sealing plate 32 at the upper end to rotate and protect the upper end of the collection hood 11.

[0027] A first inlet pipe 33 is fixed to the upper right side of the detection head 6. A first switch valve is fixed to the wall of the first inlet pipe 33. An external thread is provided at the right end of the first inlet pipe 33. An annular pipe 34 is fixed inside the collection cover 11. A disinfection nozzle 35 is fixed to the inner wall of the annular pipe 34. A second inlet pipe 36 is fixed to the right side of the annular pipe 34. A second switch valve is fixed to the wall of the second inlet pipe 36. An external thread is provided at the right end of the second inlet pipe 36. When the detection head 6 is used up, some blood will remain inside. At this time, the connecting threaded pipe 42 can be connected and fixed to the first inlet pipe 33. By starting the second pump body 40, the disinfectant in the disinfectant container 38 is discharged into the interior of the first inlet pipe 33 and into the interior of the detection head 6 for sterilization. A placement plate 37 is fixed to the upper right side of the inner wall of the storage box 1. A disinfectant container 38 is fixed to the upper side of the placement plate 37. A disinfectant adding tube 39 is fixed to the right side of the disinfectant container 38. A second pump body 40 is fixed inside the disinfectant container 38.

The threaded pipe 42 is compatible with the first inlet pipe 33 and the second inlet pipe 36.

[0028] Ultraviolet germicidal lamps 43 are fixed to the left and right ends of the inner wall of the storage box 1. When not in use, the interior of the storage box 1 can be sterilized and disinfected by the ultraviolet germicidal lamps 43.

[0029] Working principle: In use, the storage box 1 and its internal equipment can be directly carried to the corresponding usage location. The first motor 18 is started, which drives the lead screw 17 at the output end to rotate. The lead screw 17 drives the lifting block 19, which is threaded onto the rod wall, to move upwards. The lifting block 19 then drives the front fixed rod 20 to move upwards, which in turn drives the front vertical plate 4 and protective plate 3 to move upwards. The vertical plate 4 then moves the front trace element detector 5 to the top of the storage box 1. The blood to be tested is placed in the appropriate container and positioned at the bottom of the detection head 6. The first pump body 8 is then started, and the first pump body 8 pumps the blood to be tested... The test liquid is drawn into the nebulizer 7, atomized, and discharged into the trace element analyzer 5 for trace element detection. After use, the trace element analyzer 5 is moved to the storage box 1 by the lifting mechanism. The connecting threaded pipe 42 is connected and fixed to the first liquid inlet pipe 33. The second pump body 40 is started, and the second pump body 40 discharges the disinfectant in the disinfectant container 38 into the detection head 6, thereby sterilizing and disinfecting the inside of the nebulizer 7 and the first pump body 8. The disinfectant is collected through the collection hood 11 and finally stored in the waste liquid collection box 9. Disconnect the threaded pipe 42 from the first inlet pipe 33 and connect and fix it to the second inlet pipe 36. By activating the telescopic cylinder 27, the telescopic cylinder 27 drives the second fixed block 26 to move upward, and the second fixed block 26 drives the moving pipe 10 to move upward, so that the moving pipe 10 drives the upper collection cover 11 to the outside of the detection head 6. The second pump body 40 is activated again, and the second pump body 40 discharges the disinfectant inside the disinfectant container 38 into the interior of the annular pipe 34 through the second inlet pipe 36, and discharges it through the disinfection nozzle 35 on the side wall of the annular pipe 34 to sterilize and disinfect the outer wall of the detection head 6. After the disinfection is complete, the second motor 29 is activated, and the second motor 29 drives the rotating rod 30 and the mounting bracket 31 at the output end to rotate. The mounting bracket 31 drives the sealing plate 32 to rotate, thereby sealing the upper end of the collection cover 11.
