Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0037] Example 1:

[0038] This invention provides a detection device for detecting Helicobacter pylori urease in human saliva, such as... Figures 1 to 10 As shown, the device includes the main body 1 of the Helicobacter pylori detection device. A protective device is provided on the top of one side of the moving plate 3. The protective device includes two rotating pages 12, two moving protrusions 13, and two moving blocks 14. The protective device is used to protect the quality control sample. The components of the quality control sample are saliva, antiserum reagent, enzyme-linked antibody reagent, and o-phenylenediamine. O-phenylenediamine is the substrate of the enzyme. Other substrates can be replaced here according to the enzyme produced.

[0039] The main body 1 of the Helicobacter pylori detection device has a feed trough 2 starting from the bottom of one side of its outer wall. A movable plate 3 is slidably connected to the inner wall of the feed trough 2. A placement dish 4 for preparing quality control samples is rotatably connected to the top inner wall of one side of the movable plate 3. A sliding frame 5 is fixedly installed on the top of the main body 1 of the Helicobacter pylori detection device. Three sliding blocks 6 are provided on the outer wall of the sliding frame 5. The two sliding blocks 6 closest to the feed trough 2 are slidably connected to the sliding frame 5, and the sliding blocks 6 away from the feed trough 2 are fixedly connected to the sliding frame 5. A sliding rod 7 is fixedly installed at the bottom of each of the three sliding blocks 6. Three sliding rods 7 are slidably connected to a medicine tank 8 on their outer walls. A sealing block 9 is fixedly installed at the bottom of each of the three sliding rods 7. The sealing block 9 is semi-circular in shape. The bottom outlet shape of the medicine tank 8 is the same as the top shape of the sealing block 9. A first spring 10 is fixedly installed at the top of each of the three medicine tanks 8. The tops of the three first springs 10 are respectively fixedly connected to the bottoms of the three sliding rods 7. Two symmetrical fixing rods 11 are fixedly installed at the bottom of the inner wall of the main body 1 of the Helicobacter pylori detection device. The bottom outer walls of the two rotating blades 12 are rotatably connected to the top inner wall of one side of the moving plate 3. Torsion springs are provided at the connection points between the two rotating blades 12 and the moving plate 3. The two rotating blades 12 are located on both sides of the placement dish 4. The inner walls of the two rotating blades 12 closest to the placement dish 4 are slidably connected to the outer walls of two moving protrusions 13. Bolts are threaded onto the inner walls of both sides of the two moving protrusions 13, and the bottoms of the bolts are threaded onto the bottom inner walls of the corresponding rotating blades 12. The bottoms of the two moving blocks 14 are slidably connected to the top outer wall of one side of the moving plate 3. The two moving blocks 14 are respectively connected to the outer walls of the two rotating blades 12. On the side away from the placement dish 4, two symmetrical round rods 15 are fixedly installed on the side of each of the two moving blocks 14 away from the rotating page 12. A second spring 16 is fixedly installed on the side of each round rod 15 away from the moving block 14. The outer wall of the round rod 15 is slidably connected to the inner wall of one side of the moving plate 3. The other side of the second spring 16 is fixedly connected to the inner wall of one side of the moving plate 3. The moving protrusion 13 is semi-teardrop shaped. The bottom of the medicine tank 8 is conical. A third spring 17 is provided between each of the three sliding blocks 6. The third spring 17 is sleeved on the sliding frame 5.

[0040] The working principle of the above components is as follows: When detecting Helicobacter pylori urease in human saliva, firstly, the two moving blocks 14 are pushed away from the placement dish 4, so that the rotating page 12 is no longer squeezed. The torsion spring on the rotating page 12 will push the rotating page 12 to rotate to a position perpendicular to the moving plate 3. At this time, the placement dish 4 will leak out. Then, the saliva extract is placed into the placement dish 4. Then, the moving blocks 14 are released, and the moving blocks 14 will push the rotating page 12 to cover the placement dish 4, thereby preventing dust from entering the placement dish 4. Then, the moving plate 3 is placed into the feed trough 2 and pushed so that the moving blocks 14 contact the fixing rod 11. At this time, it will... Figure 2As shown, the movable block 14 gradually opens along the shape of the fixed rod 11. At this time, the rotating page 12 will open, and the placement dish 4 will leak out again. After the movable block 14 opens, the movable protrusion 13 will contact the bottom of the medicine tank 8 as the movable plate 3 moves. Because the bottom of the medicine tank 8 is conical, the bottom of the medicine tank 8 will press the movable protrusion 13 away from the placement dish 4. At this time, the movable protrusion 13 will push the medicine tank 8 and the sliding block 6 to move to another medicine tank 8. Continue to push the movable plate 3 to move the two medicine tanks 8 to the last medicine tank 8. The sliding block 6 connected to the last medicine tank 8 is fixedly connected to the sliding rod 7, so it can no longer be pushed. When the three medicine tanks 8 move, the moving protrusion 13 will squeeze the first medicine tank 8 upward, and the medicine tank 8 will squeeze the second spring 16 upward. At this time, the bottom of the medicine tank 8 will no longer be in contact with the sealing block 9, and the medicine in the medicine tank 8 will flow to the placement dish 4 from the bottom of the medicine tank 8. When the user continues to push the moving plate 3, the moving protrusion 13 will squeeze the three medicine tanks 8 upward, so that each medicine will quickly and sequentially enter the placement dish 4, thereby shortening the reaction time between the medicine and saliva. At the same time, because the moving protrusion 13 is teardrop-shaped, when the highest point of the moving protrusion 13 touches the bottom of the medicine tank 8, the medicine tank 8 will gradually come into contact with the sealing block 9, thereby preventing the medicine from leaking.

[0041] At the same time, to prevent the potion tank 8 from moving around unnecessarily, such as Figure 10 As shown, two magnets are installed on the main body 1 of the Helicobacter pylori detection device. When the test is finished, the medicine tank 8 is pushed back to its original position by the second spring 16. At this time, the sliding block 6 will be attracted by the magnet, thus preventing the medicine tank 8 from moving randomly.

[0042] The bottom of the movable plate 3 is equipped with a driving device, which includes a magnet 19 and a gear 20. The driving device is used to drive the stirring rod 18 to rotate.

[0043] A stirring rod 18 is placed at the bottom of the placement dish 4. The bottom of the magnet 19 is fixedly connected to the top of the gear 20. The connection between the magnet 19 and the gear 20 is rotatably connected to the bottom of the moving plate 3. The magnet 19 is magnetically connected to the stirring rod 18. Two symmetrical connecting blocks 21 are fixedly installed at the bottom of the main body 1 of the Helicobacter pylori detection device. One of the connecting blocks 21 has several toothed blocks on the side near the moving plate 3, and the toothed blocks mesh with the outer wall of the gear 20.

[0044] The working principle of the above components is as follows: In order for the medicine to react with saliva more quickly, a drive device is set up. When the moving plate 3 moves to the bottom of the first medicine tank 8, the gear 20 will mesh with the tooth block on the connecting block 21, thereby driving the magnet 19 to rotate. When the magnet 19 rotates, it will drive the stirring rod 18 at the bottom of the medicine tank 8 to rotate, thereby driving the various medicines and saliva to be fully stirred.

[0045] It should be noted that, in order to prevent the medicine from spilling, toothed blocks are only installed at the bottom of the three medicine tanks 8 to control the rotation frequency of the stirring rod 18. At the same time, the stirring rod 18 is also relatively small in size, so as not to cause the liquid to rotate too fast.

[0046] A spring piece 22 is fixedly installed at the bottom of the movable plate 3. The spring piece 22 contacts the outer wall of one side of the gear 20. A hollow copper tube 23 is fixedly installed at the bottom of the movable plate 3. The hollow copper tube 23 contacts the outer wall of one side of the spring piece 22.

[0047] The working principle of the above components is as follows: In order to remind the user that the gear 20 has contacted the tooth block, a spring 22 is set. When the gear 20 rotates, it will push the spring 22. After the spring 22 is pushed, it will hit the hollow copper tube 23, thereby making a sound to remind the user to pay attention to the speed of pushing the moving plate 3, so as to avoid the stirring rod 18 rotating too fast.

[0048] Working principle: When testing human saliva for Helicobacter pylori urease, the rotating flap 12 is opened, saliva is placed into the placement dish 4, and then the rotating flap 12 is closed to cover the placement dish 4 to prevent dust from entering. Next, the moving plate 3 is placed into the feed trough 2 and pushed, causing the moving block 14 to contact the fixed rod 11. The moving block 14 gradually opens along the shape of the fixed rod 11, at which point the rotating flap 12 opens, and the placement dish 4 is exposed again. Simultaneously, the moving protrusion 13 pushes the reagent tank 8 and the sliding block 6 to move towards another reagent tank 8. When the moving plate 3 is continuously pushed, the two medicine tanks 8 will move towards the last medicine tank 8. Since the sliding block 6 connected to the last medicine tank 8 is fixedly connected to the sliding rod 7, the moving protrusion 13 will squeeze the three medicine tanks 8 upward in sequence. As the medicine tanks 8 move upward, the medicine in the medicine tanks 8 will flow from the bottom of the medicine tanks 8 to the placement dish 4. At the same time, the gear 20 will mesh with the toothed block on the connecting block 21 to drive the magnet 19 to rotate. The magnet 19 will drive the stirring rod 18 at the bottom of the medicine tank 8 to rotate, thereby driving the various medicines and saliva to be fully stirred.

[0049] Example 2:

[0050] This invention also provides a method for preparing a quality control sample, which includes the following steps:

[0051] Step 1: Open the rotating flap 12, then place the saliva extract into the placement dish 4, then close the rotating flap 12 to cover the placement dish 4, and then place the moving plate 3 into the feed tank 2;

[0052] Step 2: Push the moving plate 3 to move in the feeding trough 2. The moving block 14 will open along the fixed rod 11 and drive the rotating page 12 to open. At the same time, the moving protrusion 13 will contact the bottom of the medicine tank 8 and push the three medicine tanks 8 upward in sequence, so that the medicine in the medicine tank 8 flows to the placement dish 4.

[0053] Step 3: Then pull the moving plate 3 away from the main body 1 of the Helicobacter pylori detection device, so that the moving protrusion 13 pushes the three medicine tanks 8 upward again, so that the medicine flows into the placement dish 4 again, increasing the amount of medicine and the reaction with saliva.

[0054] Step 4: Finally, remove the movable plate 3, and then push the two movable blocks 14 away from the placement dish 4 to open the rotating page 12. At this time, observe the quality control sample in the placement dish 4.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
