[0001] This invention belongs to the field of blood testing technology, and specifically relates to a blood testing device and a blood testing method. Background Technology

[0002] Blood tests are also used to analyze blood cells and are one of the most widely used instruments in hospital clinical laboratories. With the rapid development of computer technology in recent years, blood cell analysis technology has also shifted from three-part differential analysis to five-part differential analysis, and from two-dimensional space to three-dimensional space. Moreover, we have noticed that many of the five-part differential analysis technologies of modern blood cell analyzers use the same technologies as today's very advanced flow cytometers, such as scattered light detection technology, sheath flow technology, laser technology, etc.

[0003] Currently, blood testing devices are used by inserting a test tube containing blood into the blood testing probe to perform the test. However, the probe needs to be manually cleaned repeatedly during use, and it is difficult to clean it thoroughly.

[0004] Therefore, it is necessary to invent a blood testing device and a blood testing method to solve the above problems. Summary of the Invention

Multiple cleaning channels are opened inside the side wall of the cleaning tube, and several spray holes are opened between the cleaning channels and the inner wall of the cleaning tube.

[0008] Furthermore, a pressure sleeve is slidably fitted onto the surface of the connecting bend, and an L-shaped pressure rod is fixedly connected to one side of the pressure sleeve. A groove matching the connecting bend, the pressure sleeve, and the L-shaped pressure rod is opened inside the auxiliary plate, and a first spring is provided between the bottom of the L-shaped pressure rod and the groove.

[0009] Furthermore, the connecting bend has multiple first limiting balls movably inserted into the side wall at the insertion position of the plug tube. A first slider is fixedly connected to the surface of the first limiting ball. The connecting bend has a groove matching the first slider on the side wall at the insertion position of the first limiting ball, and a first sliding rod is provided inside the groove. The first slider is slidably connected to the first slider, and a second spring is sleeved on the surface of the first sliding rod. A first limiting groove matching the first limiting ball is formed on the surface of the plug tube.

[0010] Furthermore, the top of the cleaning tube is provided with a probe hole, and the side wall of the probe hole is provided with a drying groove. Two drying semi-rings are slidably arranged inside the drying groove, and the inner wall of the drying semi-rings is provided with drying cotton. The drying cotton is connected to the drying semi-rings by an adhesive method. The two drying semi-rings can completely wrap the side wall of the blood detection probe with the drying cotton.

[0011] Furthermore, a first push rod is movably inserted into the top of the cleaning tube near both ends. A push block is fixedly connected to one side of the first push rod. One end of the push block extends into the drying tank. The bottom of the push block and the surface of the drying semi-ring are both set in matching arc shapes. A third spring is provided at the bottom of the first push rod.

[0012] Furthermore, a second slider is fixedly connected to the bottom of each of the two drying semi-rings, and a second slide rod is fixedly connected inside the drying trough and slidably disposed with the second slider, and a fourth spring is sleeved on the surface of the second slide rod.

[0013] Furthermore, a positioning block is movably inserted into the other side of the first push rod, and a fifth spring is connected between the positioning block and the inside of the first push rod. The cleaning tube is provided with a positioning groove that matches the positioning block at the position where the first push rod is inserted, and the distance between the positioning groove and the positioning block is equal to the distance the drying half-ring moves.

[0014] Furthermore, a second push rod is movably inserted into each of the two sides of the cleaning tube at the position of the positioning groove. The end of the second push rod near the positioning groove is fixedly connected to a pushing protrusion that matches the positioning groove. A sixth spring is connected between the second push rod and the inner wall of the cleaning tube.

[0015] Furthermore, a test tube baffle is fixedly installed on the surface of the auxiliary plate. The test tube baffle is U-shaped, and a second limiting ball is movably inserted into the inner walls on both sides. A seventh spring connects the second limiting ball and the test tube baffle. A threaded block is fixedly connected to one end of the auxiliary plate. A groove matching the threaded block is opened on the side wall of the analyzer body, and a threaded rod is installed inside the groove. A drive motor is installed at one end of the threaded rod, and the threaded rod is threadedly connected to the threaded block.

[0016] This invention also discloses a blood detection method using a blood detection device, characterized by comprising the following steps:

[0017] S1: When testing blood, place the test tube containing blood inside the test tube baffle on the surface of the blood testing auxiliary device, push the second limiting ball to retract, so that the test tube enters the interior of the test tube baffle, and then start the drive motor to drive the threaded rod to rotate, which drives the auxiliary plate to move through the threaded block, so that the blood testing probe is inserted into the test tube to test the blood.

[0018] S2: After the test is completed, the drive motor reverses, the auxiliary board returns to its original position, the test tube is removed, and the test report is printed by the analyzer.

[0019] S3: When the blood test is completed or another blood test is required, use the blood test auxiliary device to clean the blood test probe. Take out the cleaning tube used to clean the blood test probe, manually press the L-shaped pressure rod to move the pressure sleeve downward, exposing the position where the first limiting ball and the connecting bend are inserted. Then insert the insertion head at the bottom of the cleaning tube into the inside of the connecting bend, and let the first limiting ball enter the first limiting groove. Then release the L-shaped pressure rod to return the pressure sleeve to its original position, thereby connecting and fixing the cleaning tube and the connecting bend.

[0020] S4: Start the drive motor to move the auxiliary plate upwards along the cleaning tube until the blood test probe is fully inside the cleaning tube. This will cause the first push rod to be squeezed, pushing out the two drying semi-rings and allowing the drying cotton to wrap around the blood test probe. Then, stop the drive motor and start the pressure water pump to spray the cleaning solution inside the disinfection and cleaning tank into the cleaning tube through the connecting bend and plug tube. The inlet at the bottom of the cleaning tube is blocked by the stopper ball, allowing the cleaning solution to enter the cleaning channel and then spray out through the spray hole to clean the blood residue on the blood test probe.

[0021] S5: After cleaning is completed, the cleaning fluid inside the cleaning pipe is pumped back into the disinfection cleaning water tank by a pressure water pump. During this process, the ball is dropped onto the mesh frame to facilitate the extraction of the cleaning fluid inside the cleaning pipe.

[0022] S6: Reverse drive motor, which drives the auxiliary plate to return to its original position. During the return process, dry cotton is used to wipe the surface of the blood test probe from top to bottom to achieve the cleaning effect of the blood test probe.

[0023] S7: When the cleaning tube is completely removed from the position of the blood test probe, remove the cleaning tube using the method in step S3, and press the second push rod to return the two drying half-rings to their original positions, and then proceed with the next blood test.

[0024] The technical effects and advantages of this invention are as follows:

[0025] 1. This invention assists in blood testing, allowing for automatic testing simply by placing a blood-filled test tube into it. After testing, a cleaning tube can be attached to complete the cleaning process. Mechanical cleaning is more thorough, improving subsequent testing results, increasing cleaning efficiency, and making it convenient to use.

The cleaning tube 402 has multiple cleaning channels 409 inside its side wall, and multiple spray holes 410 are provided between the cleaning channels 409 and the inner wall of the cleaning tube 402. The auxiliary plate 401 is also fixedly provided with a test tube baffle 21. The test tube baffle 21 is U-shaped, and a second limiting ball 22 is movably inserted into both inner walls. A seventh spring 23 is connected between the second limiting ball 22 and the test tube baffle 21. A threaded block 24 is fixedly connected to one end of the auxiliary plate 401. The analyzer body 1 has a groove matching the threaded block 24 on its side wall, and a threaded rod 25 is provided inside the groove. A drive motor 26 is provided at one end of the threaded rod 25, and the threaded rod 25 is threadedly connected to the threaded block 24.

[0043] When performing a blood test, a test tube containing blood is placed inside the test tube baffle 21 on the surface of the blood testing auxiliary device 4. The second limiting ball 22 is pushed to retract, causing the test tube to enter the test tube baffle 21. Then, the drive motor 26 is activated, causing the threaded rod 25 to rotate. This rotation, via the threaded block 24, moves the auxiliary plate 401, thereby inserting the blood testing probe 3 into the test tube to perform the blood test.

[0044] like Figure 1-7As shown, a pressure sleeve 411 is slidably fitted onto the surface of the connecting bend 404. An L-shaped pressure rod 412 is fixedly connected to one side of the pressure sleeve 411. A groove matching the connecting bend 404, the pressure sleeve 411, and the L-shaped pressure rod 412 is opened inside the auxiliary plate 401.

Then, the insertion head 403 at the bottom of the cleaning tube 402 is inserted into the interior of the connecting bend 404, and the first limiting ball 414 enters the interior of the first limiting groove 5. Then, the L-shaped pressure rod 412 is released, allowing the pressure sleeve 411 to return to its original position, thereby connecting and fixing the cleaning tube 402 and the connecting bend 404. The drive is then activated. The machine 26 causes the auxiliary plate 401 to move the cleaning tube 402 upward until the blood detection probe 3 is completely inside the cleaning tube 402, and the first push rod 10 is squeezed to push out the two drying half rings 8, so that the drying cotton 9 wraps the blood detection probe 3. Then the drive motor 26 is stopped and the pressure water pump 406 is started to spray the cleaning solution inside the disinfection cleaning water tank 405 into the cleaning tube 402 through the connecting bend pipe 404 and the plug pipe. The inlet at the bottom of the cleaning tube 402 is blocked by the blocking ball 408, so that the cleaning solution enters the cleaning channel 409 and is then sprayed out through the spray hole 410 to clean the bloodstains remaining on the blood detection probe 3.

[0046] like Figure 1-11As shown, the top of the cleaning tube 402 has a probe hole 6, and the side wall of the probe hole 6 has a drying groove 7. Two drying semi-rings 8 are slidably arranged inside the drying groove 7, and the inner wall of the drying semi-rings 8 is provided with drying cotton 9. The drying cotton 9 is connected to the drying semi-rings 8 by adhesive. The two drying semi-rings 8 can completely wrap the side wall of the blood detection probe 3 using the drying cotton 9.

[0047] After cleaning is completed, the cleaning fluid inside the cleaning tube 402 is re-pumped into the disinfection and cleaning water tank 405 by the pressure water pump 406. During this process, the ball stopper 408 falls onto the mesh frame 407, which facilitates the extraction of the cleaning fluid inside the cleaning tube 402. The reverse drive motor 26 is reversed, causing the auxiliary plate 401 to return to its original position. During the return process, the surface of the blood detection probe 3 is wiped from top to bottom with dry cotton 9 to achieve the cleaning effect of the blood detection probe 3.

The second limiting ball 22 is pushed to retract, so that the test tube enters the test tube baffle 21. Then the drive motor 26 is started, so that the drive motor 26 drives the threaded rod 25 to rotate. Through the threaded block 24, the auxiliary plate 401 is moved, so that the blood testing probe 3 is inserted into the test tube to test the blood.

[0050] S2: After the test is completed, the drive motor 26 reverses, the auxiliary board 401 returns to its original position, the test tube is taken out, and the analyzer body 1 waits for the test report to be printed.

[0052] S4: Start the drive motor 26, causing the auxiliary plate 401 to move the cleaning tube 402 upward until the blood detection probe 3 is completely inside the cleaning tube 402, and the first push rod 10 is squeezed, pushing out the two drying half rings 8, so that the drying cotton 9 wraps the blood detection probe 3. Then stop the drive motor 26, start the pressure water pump 406, and spray the cleaning solution inside the disinfection cleaning water tank 405 into the cleaning tube 402 through the connecting bend pipe 404 and the plug pipe. The inlet at the bottom of the cleaning tube 402 is blocked by the blocking ball 408, so that the cleaning solution enters the cleaning channel 409 and is then sprayed out through the spray hole 410 to clean the bloodstains remaining on the blood detection probe 3.

[0053] S5: After cleaning is completed, the cleaning fluid inside the cleaning pipe 402 is re-drawn into the disinfection and cleaning water tank 405 by the pressure water pump 406. During this process, the ball stopper 408 falls onto the mesh frame 407 to facilitate the extraction of the cleaning fluid inside the cleaning pipe 402.

[0054] S6: Reverse drive motor 26, causing auxiliary plate 401 to return to its original position, and during the return process, dry cotton 9 is used to wipe the surface of blood detection probe 3 from top to bottom to achieve the cleaning effect of blood detection probe 3.

[0055] S7: When the cleaning tube 402 is completely removed from the position of the blood detection probe 3, remove the cleaning tube 402 using the method in step S3, and press the second push rod 18 to restore the two drying half rings 8 to their original positions, and then perform the next blood test.
