The placement plate 132 can be used to place the test card, and the shaft of the disc 13 is connected to the output shaft of the drive motor 5 through a synchronous belt assembly.

[0023] First, the operator removes the mounting frame 131 from the disc 13, puts the four test cards into the four placement plates 132 respectively, and then snaps the mounting frame 131 back onto the disc 13, so that the test cards are under the rear sampling tube 4. Then, a patient's urine sample is placed in the notch of the fixing seat 2, and the urine sample is under the right sampling tube 4. The servo motor 12 is started to drive the screw rod 121 to rotate forward, and the screw rod 121 rotates forward to drive the limit frame 7 to move downward, and the limit frame 7 moves downward to drive the sampling tube 4 to move downward, and the right sampling tube 4 moves downward and contacts the urine. The servo motor 12 is turned off, and the screw rod 121 stops driving the limit frame 7 to move downward, and the sampling tube 4 also stops moving downward, and then the right electric push rod 11 is started, and the extension and contraction of the right electric push rod 11 The rod is extended to drive the right movable plate 9 to move upward, and the right movable plate 9 drives the right U-shaped limit rod 10 to move upward. The upward movement of the right U-shaped limit rod 10 drives the piston rod of the right sampling tube 4 to move upward, so that the right sampling tube 4 extracts urine. When a proper amount of urine is extracted from the right sampling tube 4, the right electric push rod 11 is closed, and the servo motor 12 is started to drive the screw rod 121 to reverse. The screw rod 121 reverses and drives the limit frame 7 to move upward and reset, which also makes the sampling tube 4 move upward and reset. The right sampling tube 4 is reset and out of contact with urine. Then the driving motor 5 is started to drive the rotating seat 3 to reverse ninety degrees. The reverse rotation of the rotating seat 3 drives the sampling tube 4 to reverse. The sampling tube 4 with urine extracted is reversed to the top of the detection card, and the next sampling tube 4 is reversed to the fixed seat 2, take out the urine container placed in the fixing seat 2, put the next urine container into the notch of the fixing seat 2, turn off the driving motor 5, the rotating seat 3 stops driving the sampling tube 4 to reverse, at this time, start the servo motor 12 again to drive the screw rod 121 to rotate forward, so that the limiting frame 7 moves downward to drive the sampling tube 4 to move downward, the sampling tube 4 filled with urine moves downward to approach the detection card, and the right sampling tube 4 moves downward to contact the urine, turn off the servo motor 12, and then start the electric push rod 11 on the rear side, the telescopic rod of the electric push rod 11 on the rear side shortens and drives the rear movable plate 9 to move downward, because the sampling tube 4 is limited by the limiting frame 7, the rear movable plate 9 drives the piston rod of the rear sampling tube 4 to move downward through the rear U-shaped limiting rod 10, The rear sampling tube 4 pushes out the urine and drips it onto the detection card for detection. At the same time, the right electric push rod 11 is started to drive the right movable plate 9 to move upward, which makes the right U-shaped limit rod 10 drive the piston rod of the right sampling tube 4 to move upward, and the right sampling tube 4 extracts the urine. In this way, the next urine sample can be extracted and collected while the urine is dripping on the detection card, so that the next urine sample can be extracted without waiting for the urine to drip, thereby meeting the needs of continuous detection and improving the efficiency of urine detection. When the urine dripping is completed, the servo motor 12 is started to drive the screw rod 121 to reverse and drive the limit frame 7 to move upward and reset, which makes the sampling tube 4 move upward and reset, and then the urine sample in the fixed seat 2 is replaced again.Start the driving motor 5 to drive the rotating seat 3 to reverse 90 degrees, so that the next sampling tube 4 is reversed to the right and the sampling tube 4 with urine is reversed to the back side. At the same time, the reversal of the driving motor 5 also drives the disc 13 to reverse 90 degrees through the synchronous belt assembly. The reversal of the disc 13 drives the mounting frame 131 to reverse, and the mounting frame 131 drives the placement plate 132 to reverse 90 degrees. The reversal of the placement plate 132 drives the detection card to reverse 90 degrees, which makes the next detection card reverse 90 degrees and be under the sampling tube 4. This is repeated, urine can be continuously dripped on the detection card, and the detection card is switched. When the four sampling tubes 4 are used once, the detection of four urine samples is completed, the mounting frame 131 is removed from the disc 13 to place the detection card with urine dripping, and the new mounting frame 131 is removed from the disc 13 to place the detection card with urine dripping. The frame 131 is snapped back onto the disc 13, and then the U-shaped limit rod 10 is pushed to swing, the torsion spring 101 is compressed, the U-shaped limit rod 10 swings and disengages from the piston rod of the sampling tube 4, and the sampling tube 4 stops being limited by the U-shaped limit rod 10, and the used sampling tube 4 can be taken out from the rotating seat 3 for replacement, and the sampling tube 4 is disengaged from the limit frame 7, and the new sampling tube 4 is put back between the rotating seat 3 and the limit frame 7, and the U-shaped limit rod 10 is released. Due to the action of the torsion spring 101, the U-shaped limit rod 10 swings back to contact with the piston rod of the sampling tube 4, and the urine can continue to be tested. At the same time, the test results of the removed test card can be viewed after a period of time.

[0026] Initially, the water inlet end of the water pump 144 is connected to a container containing disinfectant and an external discharge pipe of the water outlet pipe. The water pump 144 is first started to discharge an appropriate amount of disinfectant into the cavity 14, and the disinfectant contacts the brush holder 141. The water pump 144 is turned off, and then the stepper motor 142 is started to drive the brush holder 141 to rotate.

The rotation of the rotating shaft 146 drives the wiping block 148 and the rotating blade 147 to rotate, and the rotating blade 147 rotates. The air is blown upward, and the blown air contacts the wiping block 148. The air flows in the wiping block 148 to form an airflow. Then, when the used sampling tube 4 is reversed to the top of the brush holder 141, the limiting frame 7 moves downward to drive all the sampling tubes 4 to move downward. The used sampling tube 4 moves downward into the cavity 14, and the used sampling tube 4 contacts the brush holder 141. The brush holder 141 rotates to clean and disinfect the outer wall of the sampling tube 4 with the disinfectant.
